RISK/RETURN SUMMARY
 
ABOUT THE PORTFOLIOS
- -------------------
 
The Portfolios:
 
- -  Are generally offered to institutional investors and clients of registered
   investment advisers.
 
- -  Do not charge sales commissions or "loads".
 
- -  Cost less to own than most mutual funds.
 
- -  Are designed for long-term investors.
 
The Portfolios are no-load and low cost.
 
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 Portfolios that own them, to rise or fall. Fixed income
Portfolios are particularly sensitive to changing interest rates.
 
SOME PORTFOLIOS HAVE SPECIAL STRUCTURES: Certain Portfolios, called "Feeder
Portfolios", do not buy individual securities directly. Instead, they invest in
corresponding mutual funds called "Master Funds". Master Funds in turn purchase
stocks, bonds and/or other securities.
 
   
POSSIBLE COMPLICATIONS: The Master-Feeder structure is relatively new and more
complex. While this structure is designed to reduce costs, it may not do so. As
a result, a Feeder Portfolio might encounter operational or other complications.
    
 
A Master Fund buys securities directly. A corresponding Feeder Portfolio invests
in the Master Fund's shares. The two have the same gross investment returns.
 
MANAGEMENT
- ------------
 
   
Dimensional Fund Advisors Inc. (the "Advisor") is the investment manager for
each non-Feeder Portfolio and all Master Funds. (A Feeder Portfolio does not
need an investment manager.)
    
 
EQUITY INVESTMENT APPROACH:
- -------------------------
 
The Advisor believes that equity investing should involve a long-term view and a
focus on asset class (e.g., small company stocks) selection, not stock picking.
It places priority on limiting expenses, portfolio turnover, and trading costs.
Many other investment managers concentrate on reacting to price movements and
choosing individual securities.
 
NO MARKET TIMING OR STOCK PICKING: In contrast to some other managers, the
Advisor does not take defensive positions in anticipation of negative investment
conditions, or try to pick potentially outperforming securities.
 
PORTFOLIO CONSTRUCTION: Generally, the Advisor structures a portfolio by:
 
1.  Selecting a starting universe of securities (for example, all publicly
    traded U.S. common stocks).
 
                                       3
<PAGE>
   
2.  Creating a sub-set of companies meeting the Advisor's investment guidelines.
    
 
   
3.  Excluding certain companies after analyzing various factors (for example,
    solvency).
    
 
   
4.  Purchasing stocks so the portfolio is generally market cap weighted.
    
 
U.S. Large Company Portfolio buys a Master Fund that is managed differently.
Because this Master Fund is an index fund, its only criteria for holding a stock
is whether the stock is in the S&P 500 Index.
 
In contrast, the Master Fund purchased by the Enhanced Large Company Portfolio
generally invests in S&P futures contracts and fixed income securities.
 
   
Certain Domestic Equity Portfolios use a market capitalization segmentation
approach. Broadly speaking, this technique involves:
    
 
   
1.  Dividing all the companies traded on the New York Stock Exchange ("NYSE")
    into 10 groups or "deciles" based on market capitalization. Stocks in decile
    1 have the biggest market capitalizations and those in decile 10, the
    smallest.
    
 
   
2.  Combining two or more of these deciles into a market cap segment or range.
    
 
   
3.  Generally, considering a stock (it may not necessarily be NYSE traded) for
    purchase only if its market capitalization falls within the range created.
    
 
   
For example, the Large Cap Value Portfolios buy stocks with market caps in the
range defined by stocks in NYSE deciles 1 through 5. Similarly, U.S. 6-10 Small
Company Portfolio purchases stocks with market caps equivalent to those of
stocks in NYSE deciles 6 through 10; thus its name. In fact, the name of each
other Portfolio employing a market capitalization segmentation approach also
includes the NYSE deciles describing its particular market capitalization
segment.
    
 
FIXED INCOME INVESTMENT APPROACH:
- -------------------------------
 
PORTFOLIO CONSTRUCTION: Generally, the Advisor structures a 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.
 
MARKET CAPITALIZATION MEANS the number of shares of a company's stock
outstanding times price per share.
 
MARKET CAPITALIZATION WEIGHTED means the amount of a stock in an index or
portfolio is keyed to that stock's market capitalization compared to all
eligible stocks. The higher the stock's relative market cap, the greater its
representation.
 
   
TAX MANAGED PORTFOLIO STRATEGIES:
    
- ------------------------
 
The Advisor's tax management strategies are designed to minimize taxable
distributions to shareholders. Generally, the Advisor buys and sells a tax
managed portfolio's securities with the goals of:
 
1.  Delaying the realization of net capital gains (e.g., appreciated stocks
    might be sold later).
 
2.  Maximizing the extent to which any realized net capital gains are long-term
    in nature (i.e., taxable at lower capital gains tax rates).
 
3.  Minimizing dividend income.
 
Shareholders of Tax-Managed Portfolios may save on taxes while they hold their
shares. However, they will still have to pay taxes if they sell their shares at
a profit.

INVESTMENT OBJECTIVES, STRATEGIES AND RISKS
- -----------------------------------------
 
DOMESTIC EQUITY PORTFOLIOS:
 
THE U.S. LARGE COMPANY PORTFOLIOS
- -------------------------------
 
U.S. LARGE COMPANY PORTFOLIO
 
- -  INVESTMENT OBJECTIVE: Produce returns similar to those of the S&P 500 Index.
 
- -  INVESTMENT STRATEGY: Buy shares of a Master Fund that invests in S&P 500
   Index stocks in about the same proportions as they are found in the S&P 500
   Index.
 
ENHANCED U.S. LARGE COMPANY PORTFOLIO
 
- -  INVESTMENT OBJECTIVE: Outperform the S&P 500 Index.
 
- -  INVESTMENT STRATEGY: Purchase shares of a Master Fund that generally invests
   in S&P 500 Index futures and short-term fixed income obligations.
 
ABOUT THE S&P 500 INDEX: The Standard & Poor's 500 Composite Stock Price Index
is market capitalization weighted. Its performance is usually cyclical because
it reflects periods when stock prices generally rise or fall.
 
THE U.S. VALUE PORTFOLIOS
- ----------------------
 
U.S. LARGE CAP VALUE PORTFOLIO
TAX-MANAGED U.S. MARKETWIDE VALUE PORTFOLIO
U.S. 4-10 VALUE PORTFOLIO
TAX-MANAGED U.S. 5-10 VALUE PORTFOLIO
U.S. 6-10 VALUE PORTFOLIO
 
- -  INVESTMENT OBJECTIVE(S):
 
   - TAX-MANAGED PORTFOLIOS: Long-term capital appreciation while minimizing
    federal income taxes on returns.
 
   - EACH OTHER PORTFOLIO: Long-term capital appreciation.
 
- -  INVESTMENT STRATEGY:
 
   - TAX-MANAGED U.S. 5-10 VALUE PORTFOLIO -- Purchase value stocks of United
    States companies on a market capitalization weighted basis.
 
   
   - EACH OTHER U.S. VALUE PORTFOLIO -- Buy a Master Fund that purchases value
    stocks of United States companies on a market capitalization weighted basis.
    
 
- -  HOW THE PORTFOLIOS DIFFER: The Portfolios focus on different parts of the
   value stocks universe:
 
   - U.S. Large Cap Value and Tax-Managed U.S. Marketwide Value -- Large
    capitalization stocks.
 
   - U.S. 4-10 Value and Tax-Managed U.S. 5-10 Value -- Mid and small
    capitalization issues.
 
   - U.S. 6-10 Value -- Small cap stocks.
 
   Only the Tax-Managed Portfolios employ the Advisor's tax management
   strategies.
 
   
SMALL COMPANY RISK: Securities of small firms are often less liquid than those
of large companies. As a result, small company stocks may fluctuate relatively
more in price.
    
   
"VALUE STOCKS": Compared to other stocks, value stocks sell for low prices
relative to their earnings, dividends book value.
    
In selecting value stocks, the Advisor primarily considers price relative to
book value.
 
                                       5
<PAGE>
THE U.S. SMALL COMPANY PORTFOLIOS
- -------------------------------
 
U.S. 6-10 SMALL COMPANY PORTFOLIO
TAX-MANAGED U.S. 6-10 SMALL COMPANY PORTFOLIO
U.S. 9-10 SMALL COMPANY PORTFOLIO
 
- -  INVESTMENT OBJECTIVE(S):
 
   - TAX-MANAGED U.S. 6-10 SMALL COMPANY PORTFOLIO: Long-term capital
    appreciation while minimizing federal income taxes on returns.
 
   - EACH OTHER PORTFOLIO: Long-term capital appreciation.
 
- -  INVESTMENT STRATEGY:
 
   - TAX-MANAGED U.S. 6-10 SMALL COMPANY PORTFOLIO -- Purchase small company
    stocks using a market cap weighted approach.
 
   - EACH OTHER U.S. SMALL COMPANY PORTFOLIO -- Buy a Master Fund that does so.
 
- -  HOW THE PORTFOLIOS DIFFER:
 
   The Master Fund in which U.S. 6-10 Small Company Portfolio invests, and
   Tax-Managed U.S. 6-10 Small Company Portfolio, hold stocks of small and very
   small companies. The Master Fund employed by U.S. 9-10 Portfolio exclusively
   buys stock of very small companies. Only Tax-Managed U.S. 6-10 Small Company
   Portfolio employs the Advisor's tax management strategies.
 
   
RISK OF VERY SMALL COMPANIES: Securities of very small firms are often less
liquid than those of larger companies. As a result, the stocks of very small
companies may fluctuate more in price than the stocks of larger companies.
    
 
DFA REAL ESTATE SECURITIES PORTFOLIO
 
- -  INVESTMENT OBJECTIVE: Long-term capital appreciation
 
- -  INVESTMENT STRATEGY: Invest in publicly traded real estate investment trusts
   ("REITS") on a market capitalization weighted basis.
 
   
RISK OF CONCENTRATING IN THE REAL ESTATE INDUSTRY: DFA Real Estate Securities
Portfolio's exclusive focus on the real estate industry may cause its risk to
approximate the risks of direct real estate ownership (for example, a general
decline in real estate prices would cause the Portfolio to lose money).
    
 
INTERNATIONAL PORTFOLIOS:
 
LARGE CAP INTERNATIONAL PORTFOLIO
 
- -  INVESTMENT OBJECTIVE: Long-term capital appreciation.
 
- -  INVESTMENT STRATEGY: Purchase stocks of large, non-U.S. companies on a market
   capitalization weighted basis in each applicable country.
 
Most Portfolios and Master Funds do not hedge their foreign currency risks.
 
                                       6
<PAGE>
   
FOREIGN SECURITIES AND CURRENCIES RISK: Foreign securities prices may decline or
fluctuate because of: (a) economic or political actions of foreign governments,
and/or (b) less regulated or liquid securities markets. Investors holding these
securities are also exposed to foreign currency risk (the possibility that
foreign currency will fluctuate in value against the U.S. dollar). Foreign
currency risk can be minimized by hedging. However, hedging may be expensive.
    
 
DFA INTERNATIONAL VALUE PORTFOLIO
TAX-MANAGED DFA INTERNATIONAL VALUE PORTFOLIO
 
- -  INVESTMENT OBJECTIVE:
 
   - TAX-MANAGED DFA INTERNATIONAL VALUE PORTFOLIO: Long-term capital
    appreciation while minimizing federal income taxes on returns.
 
   - DFA INTERNATIONAL VALUE PORTFOLIO: Long-term capital appreciation.
 
- -  INVESTMENT STRATEGY:
 
   - TAX-MANAGED DFA INTERNATIONAL VALUE PORTFOLIO -- Purchase value stocks of
    large non-U.S. companies on a market capitalization weighted basis in each
    applicable country.
 
   
   - DFA INTERNATIONAL VALUE PORTFOLIO -- Buy a Master Fund that purchases value
    stocks of large non-U.S. companies on a market capitalization weighted basis
    in each applicable country.
    
 
- -  HOW THE PORTFOLIOS DIFFER:
 
Only Tax-Managed DFA International Value Portfolio employs the Advisor's tax
management strategies.
 
THE INTERNATIONAL SMALL COMPANY PORTFOLIOS
- ---------------------------------------
 
   
INTERNATIONAL SMALL COMPANY PORTFOLIO
JAPANESE SMALL COMPANY PORTFOLIO
PACIFIC RIM SMALL COMPANY PORTFOLIO
UNITED KINGDOM SMALL COMPANY PORTFOLIO
CONTINENTAL (EUROPEAN) SMALL COMPANY PORTFOLIO
    
 
- -  INVESTMENT OBJECTIVE (EACH PORTFOLIO): Long-term capital appreciation.
 
- -  INVESTMENT STRATEGY OF THE INTERNATIONAL SMALL COMPANY PORTFOLIO: Invest in
   the Master Funds employed by the other International Small Company
   Portfolios.
 
- -  INVESTMENT STRATEGY OF EACH OTHER INTERNATIONAL SMALL COMPANY PORTFOLIO:
   Purchase a Master Fund that uses a market weighted approach to buy small
   company stocks of a specific country or region.
 
THE PACIFIC RIM SMALL COMPANY PORTFOLIO IS CLOSED TO NEW INVESTMENTS.
INTERNATIONAL SMALL COMPANY PORTFOLIO STOPPED BUYING THE MASTER FUND PURCHASED
BY THAT PORTFOLIO. These actions were taken because the Malaysian government
restricted the ability of foreign investors -- including the Master Fund in
question -- to withdraw their investments from Malaysia.
 
DFA INTERNATIONAL SMALL CAP VALUE
 
- -  INVESTMENT OBJECTIVE: Long-term capital appreciation.
 
                                       7
<PAGE>
- -  INVESTMENT STRATEGY: Acquire value stocks of small non-U.S. companies on a
   market capitalization weighted basis in each applicable country.
 
THE EMERGING MARKETS PORTFOLIOS
- -----------------------------
 
EMERGING MARKETS PORTFOLIO
EMERGING MARKETS VALUE PORTFOLIO
EMERGING MARKETS SMALL CAP PORTFOLIO
 
- -  INVESTMENT OBJECTIVE (EACH PORTFOLIO): Long-term capital appreciation.
 
- -  INVESTMENT STRATEGY: Invest in a Master Fund that buys:
 
   - Emerging Markets Portfolio -- Stocks of larger emerging markets companies.
 
   - Emerging Markets Small Cap Portfolio -- Stocks of smaller emerging markets
    companies.
 
   - Emerging Markets Value Fund -- Value stocks of emerging markets companies.
 
EMERGING MARKETS RISK: Numerous emerging countries have recently experienced
serious, and potentially continuing, economic and political problems. Stock
markets in many emerging countries are relatively small, expensive and risky.
Foreigners are often limited in their ability to invest in, and withdraw assets
from, these markets. Additional restrictions may be imposed under emergency
conditions. Risks generally associated with foreign securities and currencies
also apply.
 
EMERGING MARKETS are countries with more developed economies not yet at the
level of the world's mature economies.

DFA ONE-YEAR FIXED INCOME PORTFOLIO
 
- -  INVESTMENT OBJECTIVE: Maximize total return available from a universe of high
   quality fixed income investments with an average maturity of one year or
   less.
 
- -  INVESTMENT STRATEGY: Purchase shares of a Master Fund that generally acquires
   high quality obligations maturing in a year or less. The Master Fund may,
   however, take a large position in higher yielding securities maturing within
   two years. It also intends to concentrate investments in the banking industry
   in certain cases.
 
   
RISK OF BANKING CONCENTRATION: Focus on the banking industry would link the
performance of the DFA One-Year Fixed Income and/or the Two-Year Global Fixed
Income Portfolios to changes in performance of the banking industry generally.
    
 
DFA TWO-YEAR GLOBAL FIXED INCOME PORTFOLIO
 
- -  INVESTMENT OBJECTIVE: Maximize total return available from a universe of high
   quality fixed income instruments maturing in two years or less.
 
- -  INVESTMENT STRATEGY: Purchase shares of a Master Fund that buys debt
   instruments with maturities of no more than two years. Issuers might include
   the U.S. and other national governments, supranational organizations (e.g.,
   the World Bank) and domestic and foreign corporations. The
 
                                       8
<PAGE>
   Master Fund hedges all foreign currency risks. It also plans to invest
   heavily in the banking industry if particular conditions occur.
 
DFA FIVE-YEAR GOVERNMENT PORTFOLIO
 
- -  INVESTMENT OBJECTIVE: Maximize total return available from a universe of high
   quality fixed income investments maturing in five years or less.
 
- -  INVESTMENT STRATEGY: Acquire obligations of the U.S. government and its
   agencies maturing within five years, and enter into repurchase agreements
   backed by U.S. government securities.
 
DFA FIVE-YEAR GLOBAL FIXED INCOME PORTFOLIO
 
- -  INVESTMENT OBJECTIVE: Maximize total return available from a universe of high
   quality fixed income instruments maturing in five years or less.
 
- -  INVESTMENT STRATEGY: Buy obligations of issuers that might include the U.S.
   and other national governments, supranational organizations and domestic and
   foreign corporations. The Portfolio hedges all foreign currency risks.
 
DFA INTERMEDIATE GOVERNMENT FIXED INCOME PORTFOLIO
 
- -  INVESTMENT OBJECTIVE: Provide a market rate of return and relatively
   predictable income from U.S. Treasury and government agency issues with
   maturities of between five and fifteen years.
 
- -  INVESTMENT STRATEGY: Invest in top quality, low-risk obligations of the U.S.
   government and its agencies, foreign governments and supranational
   organizations.
 
OTHER RISKS
- -----------
 
DERIVATIVES:
- ----------
 
   
Derivatives are securities, such as futures contracts, whose value is derived
from that of other securities or indices. Derivatives can be used for hedging
(attempting to reduce risk by offsetting one investment position with another)
or speculation (taking a position in the hope of increasing return). DFA Two-
Year Global Fixed Income Portfolio and DFA Five-Year Global Fixed Income
Portfolio use long-term foreign currency contracts to hedge foreign currency
risks. The International Portfolios may also do so. In an attempt to achieve its
investment objectives, the Enhanced U.S. Large Company Portfolio uses index swap
agreements and stock index futures to hedge against changes in securities
prices. Hedging with derivatives may increase expenses, and there is no
guarantee that a hedging strategy will work.
    
 
INTRODUCTION OF THE EURO:
- ----------------------
 
   
On January 1, 1999, The European Monetary Union ("EMU") introduced a common
currency, the Euro, replacing its members' national currencies. This development
may affect Portfolios investing directly or indirectly (through Master Funds) in
EMU countries to the extent it changes investment practices, opportunities,
risks and investor behavior or creates administrative problems.
    
 
                                       9
<PAGE>
   
The Advisor and its global custodians are attempting to assure on an an ongoing
basis that Portfolios and Master Funds will remain unaffected by any transition
related disruptions. However, they cannot guarantee that their efforts will
succeed completely. The relative value of the U.S. dollar and Euro will
fluctuate. Accordingly, currency risk (discussed above) will continue to apply
to Portfolio and Master Fund investments in EMU countries.
    
 
SECURITIES LENDING:
- ----------------
 
Non-Feeder Portfolios and Master Funds may lend their portfolio securities to
generate additional income. If they do so, they will use various strategies (for
example, only making fully collateralized and bank guaranteed loans) to reduce
related risks.
 
YEAR 2000 ISSUE:
- --------------
 
   
Unless modified, many computer programs will not properly process information
from the year 2000 on. While the issue is international in scope, there is
particular concern with foreign entities. The Advisor has taken steps designed
to ensure that its computers and those of Portfolio and Master Fund service
providers (e.g., custodians) will operate properly. Portfolios and Master Funds
may be negatively affected if the Advisor's efforts prove inadequate, and/or
Year 2000 problems hurt portfolio securities or economic conditions generally.
    
 
RISK AND RETURN BAR CHARTS AND TABLES
- --------------------------------------
 
   
The Bar Charts and Tables below illustrate the variability of each Portfolio's
returns and is meant to provide some indicator of the risks of investing in the
Portfolios. Shown are changes in performance from year to year, and how
annualized 1 year, 5 year, and since inception returns compare with those of a
broad measure of market performance. Past performance is not an indication of
future results. The U.S. 4-10 Value, Tax-Managed Portfolios, Emerging Markets
Value and Emerging Markets Small Cap Portfolios have not been in operation for a
full year, so no information is available for them.

 (1) Reimbursement fees are charged to purchasers of shares and paid to these
    Portfolios, except in the case of certain purchases permitted to be made by
    exchange. (See "EXCHANGE OF SHARES.") They serve to offset costs incurred by
    a Portfolio when investing the proceeds from the sale of its shares. (See
    "VALUATION OF SHARES-Public Offering Price" for a more complete description
    of reimbursement fees.) The Japanese Small Company, Continental Small
    Company, Pacific Rim Small Company, Emerging Markets, Emerging Markets Small
    Cap Series of the Trust and the Dimensional Emerging Markets Value Fund
    charge a reimbursement fee to purchasers of shares equal to the
    reimbursement fee charged by its corresponding Feeder Portfolio as set forth
    above.
    
 
   
 (2) The reimbursement fee for the International Small Company Portfolio is a
    blended rate, which is based on the current target investment allocations
    among the International Master Funds. Consequently, the reimbursement fee
    for the International Small Company Portfolio will change from time to time
    if the Portfolio changes the target investment allocation in the
    International Master Funds. As of the date of this prospectus, the
    reimbursement fee for the Portfolio equals 0.675% of the net asset

    value of the shares of International Small Company Portfolio. An investor
    may call the Advisor at (310) 395-8005 for the reimbursement fee rate at the
    time of investment.
    
 
   
 (3) Feeder Portfolio
    
 
   
 (4) Effective December 1, 1995, pursuant to the terms of the current
    administration agreement with respect to the U.S. Large Company Portfolio,
    the Advisor agreed to waive its fees and/or assume the expenses of the
    Portfolio to the extent (1) necessary to pay the ordinary operating expenses
    of the Portfolio (except the administration fee); and (2) that the indirect
    expenses the Portfolio bears as a shareholder of the Master Fund, on an
    annual basis, exceed 0.025% of the Portfolio's average net assets. Beginning
    August 9, 1996, in addition to the waiver/assumption effective on December
    1, 1995, the Advisor agreed to assume expenses or waive the fee payable by
    the U.S. Large Company Portfolio under the administration agreement by an
    additional .09% of average assets on an annual basis. Under this
    arrangement, the net expense ratio was 0.15%.
    
 
   
 (5) Effective August 1, 1997, the Advisor has agreed to waive its fee under the
    administration agreement to the extent necessary to reduce the direct and
    indirect cumulative annual expenses of the Enhanced U.S. Large Company
    Portfolio to not more than 0.45% of average net assets of the Portfolio on
    an annualized basis; the Portfolio's direct and indirect cumulative annual
    expenses may exceed 0.45% of average net assets on an annualized basis
    notwithstanding this fee waiver. This arrangement does not extend to the
    fees of the Enhanced U.S. Large Company Series of the Trust. Under this
    arrangement, the net expense ratio was 0.45%.
    
 
   
 (6) "Other Expenses" are annualized estimates based on anticipated fees and
    expenses through the fiscal year ending November 30, 1999. These Portfolios
    and Master Fund had not commenced operations during the period indicated.
    
 
   
 (7) Effective August 9, 1996, the Advisor agreed to waive its administrative
    fee and assume the direct expenses of the Japanese Small Company, United
    Kingdom Small Company, Continental Small Company and Pacific Rim Small
    Company Portfolios to the extent necessary to keep the direct annual
    expenses of each Portfolio to not more than 0.47% of average net assets of
    the Portfolio on an annualized basis; this arrangement does not extend to
    the fees and expenses of the Master Funds. For the fiscal year ended
    November 30, 1998, the Advisor was not required to waive any portion of its
    fee pursuant to such agreement.
    
 
   
 (8) With respect to International Small Company Portfolio, the amount set forth
    under "Management Fee" reflects its portion of the management fee of each
    corresponding International Master Fund, which is equal to 0.10% of the
    average net assets of such Master Fund on an annual basis; the amounts set
    forth under "Other Expenses" and "Total Operating Expenses" also reflect the
    indirect payment of a portion of the expenses of the International Master
    Funds. The Advisor has agreed to waive its administration fee and assume the
    direct expenses of the International Small Company Portfolio to the extent
    necessary to keep the administration fee and direct annual expenses of the
    Portfolio to not more than 0.45% of average net assets of the Portfolio on
    an annualized basis; this arrangement does not extend to the fees and
    expenses of the International Master Funds. The Advisor was not required to
    waive fees or assume expenses for the fiscal year ended November 30, 1998.
    
 
   
 (9) With respect to Emerging Markets Value and Emerging Markets Small Cap
    Portfolios, expenses are annualized based on the period from commencement to
    November 30, 1998.
    
 
    For purposes of waivers and expense assumptions, the annual expenses are
those expenses incurred in any period consisting of twelve consecutive months.
The Advisor retains the right, subject to notification to the Board of Directors
of the relevant Fund, to modify or eliminate the waiver of a portion of its fees
or assumption of expenses in the future.

                                    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, that the Portfolio's operating expenses remain the same and current
reimbursement fees apply. Although your actual costs may be higher or lower,
based on these assumptions your costs would be:

MANAGEMENT AND ADMINISTRATIVE SERVICES
 
    The Advisor serves as investment advisor to each of the Portfolios, except
the Feeder Portfolios, and to each Master Fund. Dimensional Fund Advisors Ltd.
serves as sub-advisor of United Kingdom and Continental Small Company Series of
the Trust. DFA Australia Limited serves as sub-advisor of Japanese and Pacific
Rim Small Company Series of the Trust. Dimensional Fund Advisors Ltd. and DFA
Australia Limited also provide consulting services to the Advisor with respect
to DFA International Small Cap Value Portfolio, Large Cap International
Portfolio, DFA International Value Series, Tax-Managed DFA International Value
Portfolio, Emerging Markets Series, Emerging Markets Small Cap Series and
Dimensional Emerging Markets Value Fund. The Advisor provides each Feeder
Portfolio and International Small Company Portfolio with certain administrative
services. (See "MANAGEMENT OF THE FUNDS.")
 
DIVIDEND POLICY
 
    The Domestic and International Equity Portfolios, except the U.S. Large
Company, Enhanced U.S. Large Company, U.S. Large Cap Value, Tax-Managed U.S.
Marketwide Value and DFA International Value Portfolios, each distribute
substantially all of their own net investment income in December of each year.
U.S. Large Company, Enhanced U.S. Large Company, U.S. Large Cap Value,
Tax-Managed U.S. Marketwide Value, DFA International Value, Tax-Managed DFA
International Value, DFA Intermediate Government Fixed Income, DFA Two-Year
Global Fixed Income and DFA Five-Year Global Fixed Income Portfolios distribute
dividends from their net investment income quarterly. DFA One-Year Fixed Income
Portfolio distributes dividends from its net investment income monthly. DFA
Five-Year Government Portfolio distributes dividends from net investment income
semi-annually. The Portfolios will make any distributions from realized net
capital gains on an annual basis. (See "DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS
AND TAXES.")
 
PURCHASE, VALUATION AND REDEMPTION OF SHARES
 
    Shares of the International Equity Portfolios (except United Kingdom Small
Company, Large Cap International and DFA International Value and Tax-Managed DFA
International Value Portfolios) may be
 
                                       20
<PAGE>
purchased at a public offering price, which is equal to the net asset value of
their shares, plus a reimbursement fee. The reimbursement fee is paid to the
Portfolio whose shares are purchased and used to defray the costs associated
with investment of the proceeds from the sale of its shares. The shares of the
remaining Portfolios are sold at net asset value. The redemption price of the
shares of all of the Portfolios is equal to the net asset value of their shares.
 
    The reimbursement fee for the International Small Company Portfolio is based
on its current target investment allocations among the International Master
Funds in which it invests. The reimbursement fee for the International Small
Company Portfolio will change from time to time if the Portfolio changes the
target investment allocations in the International Master Funds. No
reimbursement fee is assessed in connection with any purchase of shares by
exchange between International Small Company Portfolio and any of the Feeder
Portfolios which invest in the International Master Funds.
 
    The value of the shares issued by each Feeder Portfolio and International
Small Company Portfolio will fluctuate in relation to the investment experience
of the Master Fund(s) in which such Portfolios invest. The value of the shares
issued by all other Portfolios will fluctuate in relation to their own
investment experience. Unlike shares of money market funds, the shares of DFA
One-Year Fixed Income Portfolio will tend to reflect fluctuations in interest
rates because the corresponding Master Fund in which the Portfolio invests does
not seek to stabilize the price of its shares by use of the "amortized cost"
method of securities valuation. (See "PURCHASE OF SHARES," "VALUATION OF SHARES"
and "REDEMPTION OF SHARES.")
 
                          U.S. LARGE COMPANY PORTFOLIO
 
INVESTMENT OBJECTIVE AND POLICIES
 
   
    U.S. Large Company Portfolio seeks, as its investment objective, to
approximate the investment performance of the S&P 500 Index, in terms of its
total investment return. The Portfolio invests all of its assets in U.S. Large
Company Series of the Trust (the "U.S. Large Company Series"), which has the
same investment objective and policies as the Portfolio. U.S. Large Company
Series intends to invest in all of the stocks that comprise the S&P 500 Index in
approximately the same proportions as they are represented in the Index. The
amount of each stock purchased for the U.S. Large Company Series, therefore,
will be based on the issuer's respective market capitalization. The S&P 500
Index is comprised of a broad and diverse group of stocks most of which are
traded on the New York Stock Exchange ("NYSE"). Generally, these are the U.S.
stocks with the largest market capitalizations and, as a group, they represent
approximately 70% of the total market capitalization of all publicly traded U.S.
stocks. Under normal market conditions, at least 95% of the U.S. Large Company
Series' assets will be invested in the stocks that comprise the S&P 500 Index.
    
 
    U.S. Large Company Series may also acquire stock index futures contracts and
options thereon in order to commit funds awaiting investment in stocks or
maintain cash liquidity. To the extent that this Series invests in stock index
futures contracts and options thereon for other than bona fide hedging purposes,
the Series will not purchase such futures contracts or options if as a result
more than 5% of its net assets would then consist of initial margin deposits and
premiums required to establish such contracts or options.
 
    Ordinarily, portfolio securities will not be sold except to reflect
additions or deletions of the stocks that comprise the S&P 500 Index, including
mergers, reorganizations and similar transactions and, to the extent necessary,
to provide cash to pay redemptions of the U.S. Large Company Series' shares. For
information concerning Standard & Poor's Rating Group, a Division of The McGraw
Hill Companies ("S&P"), and disclaimers of S&P with respect to the U.S. Large
Company Portfolio and the U.S. Large Company Series, see "STANDARD &

                     ENHANCED U.S. LARGE COMPANY PORTFOLIO
 
INVESTMENT OBJECTIVE AND POLICIES
 
    Enhanced U.S. Large Company Portfolio seeks, as its investment objective, to
achieve a total return which exceeds the total return performance of the S&P 500
Index. The Portfolio invests all of its assets in Enhanced U.S. Large Company
Series of the Trust (the "Enhanced U.S. Large Company Series"). The Enhanced
U.S. Large Company Series will have the same investment objective and policies
as the Portfolio. Enhanced U.S. Large Company Series may invest in all of the
stocks represented in the S&P 500 Index, options on stock indices, stock index
futures, options on stock index futures, swap agreements on stock indices and
shares of investment companies that invest in stock indices. Investments by the
Series in shares of investment companies are limited by the federal securities
laws and regulations governing mutual funds. The S&P 500 Index is comprised of a
broad and diverse group of stocks most of which are traded on the NYSE.
Generally, these are the U.S. stocks with the largest market capitalizations
and, as a group, they represent approximately 70% of the total market
capitalization of all publicly traded U.S. stocks.
 
    The Enhanced U.S. Large Company Series may, from time to time, also invest
in options on stock indices, stock index futures, options on stock index futures
and swap agreements based on indices other than, but similar to, the S&P 500
Index (such instruments whether or not based on the S&P 500 Index hereinafter
collectively referred to as "Index Derivatives"). The Enhanced U.S. Large
Company Series may invest all of its assets in Index Derivatives. Certain of
these Index Derivatives are speculative and may subject the Portfolio to
additional risks. Assets of the Enhanced U.S. Large Company Series not invested
in S&P 500 stocks or Index Derivatives may be invested in the same types of
short-term fixed income obligations as may be acquired by DFA Two-Year Global
Fixed Income Series and, to the extent allowed by the 1940 Act, shares of money
market mutual funds (collectively, "Fixed Income Investments") (See "INVESTMENT
OBJECTIVES AND POLICIES--FIXED INCOME PORTFOLIOS--Description of Investments").
The Series' investments in the securities of other investment companies may
involve duplication of certain fees and expenses.
 
    The percentage of assets of the Enhanced U.S. Large Company Series that will
be invested at any one time in S&P 500 Index stocks, Index Derivatives and Fixed
Income Investments may vary from time to time, within the discretion of the
Advisor and according to restraints imposed by the federal securities laws and
regulations governing mutual funds. The Enhanced U.S. Large Company Series will
maintain a segregated account consisting of liquid assets (or, as permitted by
applicable interpretations, enter into offsetting positions) to cover its open
positions in Index Derivatives to avoid leveraging of the Series.
 
    The Enhanced U.S. Large Company Series will enter into positions in futures
and options on futures only to the extent such positions are permissible with
respect to applicable rules of the Commodity Futures Trading Commission without
registering the Series or the Trust as a commodities pool operator. In addition,
the Enhanced U.S. Large Company Series may not be able to utilize Index
Derivatives to the extent otherwise permissible or desirable because of
constraints imposed by the Internal Revenue Code of 1986, as amended (the
"Code"), or by unanticipated illiquidity in the marketplace for such
instruments.
 
    It is the position of the Securities and Exchange Commission (the "SEC")
that over-the-counter options are illiquid. Accordingly, the Enhanced U.S. Large
Company Series will invest in such options only to the extent consistent with
its 15% limit on investment in illiquid securities.

                             U.S. VALUE PORTFOLIOS
 
INVESTMENT OBJECTIVES AND POLICIES
 
   
    The investment objective of each of these Portfolios is to achieve long-term
capital appreciation. U.S. Large Cap Value Portfolio, U.S. 4-10 Value Portfolio,
U.S. 6-10 Value Portfolio and Tax-Managed U.S. Marketwide Value will pursue
their investment objectives by investing all of their assets in U.S. Large Cap
Value Series (the "Large Cap Value Series"), U.S. 4-10 Value Series (the "4-10
Value Series"), U.S. 6-10 Value Series (the "6-10 Value Series") and Tax-Managed
U.S. Marketwide Value Series (the "Tax-Managed Marketwide Series") of the Trust,
respectively. These series are collectively called the "Value Master Funds."
Each Value Master Fund has the same investment objective and policies as the
corresponding Value Portfolio. The Tax-Managed U.S. 5-10 Value Portfolio invests
directly in portfolio securities. Ordinarily, each of the Value Master Funds and
Tax-Managed U.S. 5-10 Value Portfolio will invest at least 80% of its assets in
a broad and diverse group of readily marketable common stocks of U.S. companies
which the Advisor believes to be value stocks at the time of purchase.
Securities are considered value stocks primarily because a company's shares have
a high book value in relation to their market value (a "book to market ratio").
In measuring value, the Advisor may consider additional factors such as cash
flow, economic conditions and developments in the issuer's industry. Generally,
a company's shares will be considered to have a high book to market ratio if the
ratio equals or exceeds the ratios of any of the 30% of companies with the
highest positive book to market ratios whose shares are listed on the NYSE and,
except as described under "Portfolio Construction for Tax-Managed Funds," will
be considered eligible for investment. A Large Cap Value will purchase common
stocks of companies whose market capitalizations equal or exceed that of the
company having the median market capitalization of companies whose shares are
listed on the NYSE. The Tax-Managed Marketwide Value Portfolio will purchase
common stocks of companies whose market capitalization equal the market
capitalizations of companies in the 1st through
    
 
                                       23
<PAGE>
   
8th deciles of those companies listed on the NYSE. The 6-10 Value Series will
purchase common stocks of companies whose market capitalizations are smaller
than that of the company having the median market capitalization of companies
whose shares are listed on the NYSE. The 4-10 Value Series will purchase common
stocks of companies whose market capitalizations are equal to the market
capitalizations of companies in the 4th through 10th deciles of those companies
listed on the NYSE. The Tax-Managed U.S. 5-10 Value Portfolio will purchase
common stocks of companies whose market capitalizations are equal to the market
capitalizations of companies in the 5th through 10th deciles of those companies
listed on the NYSE. With respect to the 9th and 10th deciles, the 4-10 Value
Series will only purchase such common stocks when it is advantageous to do so
through block trades with the Advisor's other accounts.
    
 
   
PORTFOLIO CONSTRUCTION
    
 
    The Value Master Funds and Tax-Managed U.S. 5-10 Value Portfolio will
purchase securities that are listed on the principal U.S. national securities
exchanges or traded or the over-the-counter market ("OTC"). Each of the Value
Master Funds and Tax-Managed U.S. 5-10 Value Portfolio is market capitalization
weighted. That is, each security is generally purchased based on the issuer's
relative market capitalization. In this way, the amount of a particular security
owned by a Master Fund or Portfolio is keyed to that security's market
capitalization compared to all securities eligible for purchase.
 
    On not less than a semi-annual basis, for each Value Master Fund and
Tax-Managed U.S. 5-10 Value Portfolio, the Advisor will calculate the book to
market ratio necessary to determine those companies whose stock may be eligible
for investment. For additional information regarding the investment policies of
the Tax-Managed U.S. 5-10 Value Portfolio, including its portfolio structure and
transactions, see "TAX MANAGEMENT STRATEGIES" below.
 
PORTFOLIO TRANSACTIONS
 
    The Value Master Funds and the Tax-Managed U.S. 5-10 Value Portfolio do not
intend to purchase or sell securities based on the prospects for the economy,
the securities markets or the individual issuers whose shares are eligible for
purchase. As described under "Portfolio Structure," investments will be made in
virtually all eligible securities on a market capitalization weighted basis.
 
    Large Cap Value Series and the Tax-Managed Marketwide Series may sell
portfolio securities when the issuer's market capitalization falls substantially
below that of the issuer with the minimum market capitalization which is then
eligible for purchase by that Series. The 4-10, 6-10 Value Series and the Tax-
Managed U.S. 5-10 Value Portfolio each may sell portfolio securities when the
issuer's market capitalization increases to a level that substantially exceeds
that of the issuer with the largest market capitalization which is then eligible
for investment by those Series.
 
    In addition, Large Cap Value Series and Tax-Managed Marketwide Series may
sell portfolio securities when their book to market ratio falls substantially
below that of the security with the lowest such ratio that is then eligible for
purchase by that Series. The 4-10 and 6-10 Value Series and the Tax-Managed U.S.
5-10 Value Portfolio may also sell portfolio securities in the same
circumstances, however, each of those Series anticipates generally to retain
securities of issuers with relatively smaller market capitalizations for longer
periods, despite any decrease in the issuer's book to market ratio.
 
   
    In the case of the Tax-Managed U.S. 5-10 Value Portfolio, management
strategies which may be used by the Advisor in attempts to defer the realization
of net capital gains and to minimize dividend income may, from time to time,
cause deviation from market capitalization weighting. The Tax-Managed U.S. 5-10
Value Portfolio should not be expected to adhere to its market capitalization
weighting with the same precision as the 4-10 Value Series and the 6-10 Value
Series. (See "TAX MANAGEMENT STRATEGIES" below.)

                         U.S. SMALL COMPANY PORTFOLIOS
 
INVESTMENT OBJECTIVES AND POLICIES
 
    Each U.S. Small Company Portfolio, and the U.S. 6-10 Small Company and U.S.
9-10 Small Company Series of the Trust (the "U.S. Small Company Master Funds")
have an investment objective to achieve long-term capital appreciation. The U.S.
Small Company Portfolios provide investors with access to securities portfolios
consisting of small U.S. companies. Company size will be determined for purposes
of these Portfolios and Master Funds solely on the basis of a company's market
capitalization which will be calculated by multiplying the price of a company's
stock by the number of its shares of outstanding common stock.
 
    Each U.S. Small Company Master Fund and Tax-Managed U.S. 6-10 Small Company
Portfolio will invest at least 80% of their assets in equity securities of U.S.
companies and will be structured to reflect reasonably the relative market
capitalizations of their portfolio companies. The Advisor believes that over the
long term the investment performance of small companies is superior to large
companies. Investors which, for a variety of reasons, may choose not to make
substantial, or any, direct investment in companies whose securities will be
held by the U.S. Small Company Master Funds and Tax-Managed U.S. 6-10 Small
Company Portfolio, may participate in the investment performance of these
companies through ownership of a Portfolio's stock. The Tax-Managed U.S. 6-10
Small Company Portfolio seeks to minimize the impact of federal taxes on returns
by managing its portfolio to seek to defer the realization of net capital gains
and may seek to minimize the receipt of dividend income in order to minimized
taxable distributions to investors. For this reason, its investment policies,
including its portfolio structure and transactions, differ slightly from the
Small Company Series. For further information on the Tax-Managed U.S. 6-10 Small
Company Portfolio's investment policies, see "TAX MANAGEMENT STRATEGIES" in this
prospectus.
 
U.S. 6-10 SMALL COMPANY PORTFOLIO
 
    U.S. 6-10 Small Company Portfolio invests all of its assets in the U.S. 6-10
Small Company Series of the Trust (the "6-10 Series"), which has the same
investment objective and policies as the Portfolio. The 6-10 Series will invest
in a broad and diverse group of small U.S. companies having readily marketable
securities. References in this prospectus to a "small U.S. company" means a
company whose securities are traded in the U.S. securities markets and whose
market capitalization is not larger than the largest of those in the small
one-half (deciles 6 through 10) of companies listed on the NYSE. The 6-10 Series
will purchase common stocks of companies whose shares are listed on the NYSE,
the American Stock Exchange (the "AMEX") or traded OTC. The 6-10 Series may
invest in securities of foreign issuers which are traded in the U.S. securities
markets, but such investments may not exceed 5% of the gross assets of the
Series. It is the intention of the 6-10 Series to acquire a portion of the
common stock of each eligible NYSE, AMEX and OTC company on a market
capitalization weighted basis. (See "SMALL COMPANY MASTER FUNDS--Portfolio
Structure.") In the future, the 6-10 Series may purchase common stocks of small
U.S. companies which are listed on other U.S. securities exchanges. In addition,
the 6-10 Series is authorized to invest in private placements of
interest-bearing debentures that are convertible into common stock ("privately
placed convertible debentures"). Such investments are considered illiquid and
the value thereof together with the value of all other illiquid investments may
not exceed 15% of the value of the 6-10 Series' net assets at the time of
purchase.
 
    The Tax-Managed U.S. 6-10 Small Company Portfolio pursues its investment
objective by investing its assets generally in a similar way as the 6-10 Series,
described above. However, the Tax-Managed U.S. 6-10 Small Company Portfolio will
seek to minimize the impact of federal taxes on returns by managing its
portfolio in a manner that will defer the realization of net capital gains and
may minimize the receipt of dividend income. (See "TAX MANAGEMENT STRATEGIES"
below.)
 
                                       25
<PAGE>
U.S. 9-10 SMALL COMPANY PORTFOLIO
 
    U.S. 9-10 Small Company Portfolio pursues its investment objective by
investing all of its assets in the U.S. 9-10 Small Company Series of the Trust
(the "9-10 Series"). The 9-10 Series will invest in a broad and diverse segment
of small U.S. companies having readily marketable stocks, and whose market
capitalization is not larger than the largest of those in the quintile of
companies listed on the NYSE having the smallest market capitalizations
(smallest 20%). The 9-10 Series will purchase stocks of companies whose shares
are listed on the NYSE or AMEX or traded OTC. The 9-10 Series may invest in
securities of foreign issuers which are traded in the U.S. securities markets,
but such investments may not exceed 5% of the gross assets of the Series. There
is some overlap in the companies in which the 9-10 Series and the 6-10 Series
invest. It is the intention of the 9-10 Series to acquire a portion of the stock
of each eligible NYSE, AMEX and OTC company on a market capitalization weighted
basis. (See "SMALL COMPANY MASTER FUNDS--Portfolio Structure.") In the future,
the 9-10 Series may include stocks of small U.S. companies which are listed on
other U.S. securities exchanges. The 9-10 Series is authorized to invest in
privately placed convertible debentures and the value thereof together with the
value of all other illiquid investments may not exceed 10% of the value of the
9-10 Series' net assets at the time of purchase.

U.S. Small Company Portfolios, see "SMALL COMPANY MASTER FUNDS--Portfolio
Structure" and "SMALL COMPANY MASTER FUNDS--Portfolio Transactions."
 
                      DFA REAL ESTATE SECURITIES PORTFOLIO
 
INVESTMENT OBJECTIVE AND PORTFOLIO
 
    The investment objective of DFA Real Estate Securities Portfolio is to
achieve long-term capital appreciation. The Portfolio will concentrate
investments in readily marketable equity securities of companies whose principal
activities include development, ownership, construction, management, or sale of
residential, commercial or industrial real estate. Investments will include,
principally, equity securities of companies in the following sectors of the real
estate industry: certain real estate investment trusts and companies engaged in
residential construction and firms, except partnerships, whose principal
business is to develop commercial property. In the future, the Advisor may
determine to include companies in other sectors of the real estate industry in
the Portfolio.
 
    The Portfolio will invest in shares of real estate investment trusts
("REITS"). REITS pool investors' funds for investment primarily in income
producing real estate or real estate related loans or interests. A REIT is not
taxed on income distributed to shareholders if it complies with several
requirements relating to its organization, ownership, assets, and income and a
requirement that it distribute to its shareholders at least 95% of its taxable
income (other than net capital gains) for each taxable year. REITS can generally
be classified as Equity REITS, Mortgage REITS and Hybrid REITS. Equity REITS
invest the majority of their assets directly in real property and derive their
income primarily from rents. Equity REITS can also realize capital gains by
selling properties that have appreciated in value. Mortgage REITS invest the
majority of their assets in real estate mortgages and derive their income
primarily from interest payments. Hybrid REITS combine the characteristics of
both Equity REITS and Mortgage REITS. At the present time, the Portfolio intends
to invest only in Hybrid REITS and Equity REITS.
 
    It is anticipated that, ordinarily, at least 80% of the net value of the
Portfolio will be invested in securities of companies in the U.S. real estate
industry. The Portfolio will make equity investments only in securities traded
in the U.S. securities markets, principally on the NYSE, AMEX and OTC. In
addition, the Portfolio is authorized to lend its portfolio securities (see
"SECURITIES LOANS"), and to purchase and sell financial futures contracts and
options thereon. To the extent that the Portfolio invests in futures contracts
and options thereon for other than bona fide hedging purposes, the Portfolio
will not purchase futures contracts or options thereon, if, as a result, more
than 5% of its net assets would then consist of initial margin deposits and
premiums required to establish such positions.
 
                                       26
<PAGE>
   
PORTFOLIO CONSTRUCTION
    
 
    The Advisor has prepared and will maintain a schedule of eligible
investments consisting of equity securities of all companies in the sectors of
the real estate industry described above as being presently eligible for
investment. It is the intention of the Portfolio to purchase a portion of the
equity securities of all of these companies on a market capitalization weighted
basis.
 
    The Portfolio will be structured by generally basing the amount of each
security purchased on the issuer's relative market capitalization in relation to
other eligible issuers in the real estate industry. However, even though a
company's stock may meet the applicable criteria described above, it will not be
purchased by the Portfolio if, at the time of purchase, in the judgment of the
Advisor, the issuer is in extreme financial difficulty or is involved in a
merger or consolidation or is the subject of an acquisition which could result
in the company no longer being considered principally engaged in the real estate
business.
 
    If securities must be sold in order to obtain funds to make redemption
payments, such securities may be repurchased by the Portfolio, as additional
cash becomes available to it. However, the Portfolio has retained the right to
borrow to make redemption payments and is also authorized to redeem its shares
in kind. (See "REDEMPTION OF SHARES.") Further, because the securities of
certain companies whose shares are eligible for purchase are thinly traded, the
Portfolio might not be able to purchase the number of shares that strict
adherence to market capitalization weighting might require.
 
    Investments will not be based upon an issuer's dividend payment policy or
record. However, many of the companies whose securities will be included in the
Portfolio do pay dividends. It is anticipated, therefore, that the Portfolio
will receive dividend income. Periodically, the Advisor may expand the
Portfolio's schedule of eligible investments to include equity securities of
companies in sectors of the real estate industry in addition to those described
above as eligible for investment as of the date of this prospectus.

invest in countries which have been authorized, depending on a number of factors
such as asset growth in a portfolio and characteristics of each country's
markets.

*   As of September 10, 1998, the Master Funds and Portfolios that invest in
    Malaysian securities discontinued further investment in such securities as a
    consequence of certain restrictions imposed by the Malaysian government on
    the repatriation of assets by foreign investors such as the Master Funds and
    Portfolios.
 
   
    On September 1, 1998, the Malaysian government announced a series of capital
and foreign exchange controls on the Malaysian currency, the ringgit, and on
transactions on the Kuala Lumpur Stock Exchange, that operated to severely
constrain or prohibit foreign investors, including the corresponding Master
Funds in which certain Portfolios invest their assets, from repatriating assets.
Pursuant to these regulations, the Portfolios and Master Funds were not
permitted to convert the proceeds of the sale of their Malaysian investments
into U.S. dollars prior to September 1, 1999.
    
 
   
    As a consequence of these developments, the Portfolios and Master Funds have
stopped investing additional funds in Malaysia effective September 8, 1998. On
February 4, 1999, the Malaysian government announced the imposition of a levy on
repatriation of portfolio capital. The levy replaced the 12-month holding period
imposed under the September 1, 1998 exchange control rules. The amount of the
levy depends on the duration that funds have been held in Malaysia. With respect
to funds invested in Malaysia prior to February 15, 1999, which includes all the
funds so invested by the Portfolios and Master Funds, profits from investment
made during the 12-month holding period are exempt from imposition of a levy. A
levy will be imposed, however, on the amount of capital that is repatriated.
Although there is some confusion in the market concerning the mechanics of the
levy, it appears that any principal repatriated after one year from September 1,
1998 will not attract any levy. Principal amounts that are repatriated within
one year will be subject to a levy at a decreasing rate, depending on the
duration the principal is held. The Advisor is closely monitoring the situation
to determine when to begin divesting the Portfolios and Master Funds of their
Malaysian assets without adverse effect.
    
 
   
    With respect to the current Malaysian investments owned by the Portfolios
and Master Funds, the Portfolios and Master Funds are presently valuing the
securities at the current market prices of the Malaysian securities and
discounting the U.S. dollar-ringgit currency exchange rate. Pending further
clarification from Malaysian regulatory authorities regarding the controls
identified above, the Portfolios and Master Funds are treating their investments
in Malaysian securities as illiquid.
    
 
   
    As of March 1, 1999, Malaysian securities constitute approximately the
following percentages of the net asset value of the designated Master Funds and
Portfolios: Pacific Rim Series, 26.48%; International
    
 
                                       29
<PAGE>
   
Small Company Portfolio, 4.39%; DFA International Small Cap Value Portfolio,
2.54%; Emerging Markets Series, 6.28%; Dimensional Emerging Markets Value Fund
Inc. (Emerging Markets Value Portfolio), 9.41%; and Emerging Markets Small Cap
Series, 7.87%. Malaysian securities constitute less than one percent of the net
asset value of the Large Cap International Portfolio and the DFA International
Value Series.
    
 
                       LARGE CAP INTERNATIONAL PORTFOLIO
 
INVESTMENT OBJECTIVE AND POLICIES
 
    The investment objective of Large Cap International Portfolio is to achieve
long-term capital appreciation by investing in the stocks of non-U.S. large
companies. The Portfolio intends to invest in the stocks of large companies in
Europe, Australia and the Far East.
 
    Under normal market conditions, at least 65% of the Portfolio's assets will
be invested in companies organized or having a majority of their assets in or
deriving a majority of their operating income in at least three non-U.S.
countries. The Portfolio reserves the right to invest in index futures contracts
to commit funds awaiting investment or to maintain liquidity. To the extent that
the Portfolio invests in index futures contracts for other than bona fide
hedging purposes, the Portfolio will not purchase futures contracts if as a
result more than 5% of its total assets would then consist of initial margin
deposits on such contracts.
 
    The Portfolio will be approximately market capitalization weighted. In
determining market capitalization weights, the Advisor, using its best judgment,
will seek to eliminate the effect of cross holdings on the individual country
weights. As a result, the weighting of certain countries in the Portfolio may
vary from their weighting in international indices such as those published by
The Financial Times, Morgan Stanley Capital International or Salomon/Russell.
The Advisor, however, will not attempt to account for cross holdings within the
same country. Generally, the companies whose stocks will be selected by the
Advisor for the Portfolio will be in the largest 50% in terms of market
capitalization for each country.
 
   
    It is management's belief that the stocks of large companies offer, over a
long term, a prudent opportunity for capital appreciation, but, at the same
time, selecting a limited number of large company stocks for inclusion in the
Portfolio involves greater risk than including a large number of them.
    
 
    The Portfolio does not seek current income as an investment objective and
investments will not be based upon an issuer's dividend payment policy or
record. However, many of the companies whose securities will be included in the
Portfolio do pay dividends. It is anticipated, therefore, that the Portfolio
will receive dividend income.
 
                       DFA INTERNATIONAL VALUE PORTFOLIO
 
INVESTMENT OBJECTIVE AND POLICIES
 
    The investment objective of DFA International Value Portfolio is to achieve
long-term capital appreciation. The Portfolio invests all of its assets in the
DFA International Value Series of the Trust (the "International Value Series"),
which has the same investment objective and policies as the Portfolio. The
International Value Series seeks to achieve its objective by investing in the
stocks of large non-U.S. companies that the Advisor believes to be value stocks
at the time of purchase. Securities are considered value stocks primarily
because a company's shares have a high book value in relation to their market
value (a "book to market ratio"). In measuring value, the Advisor may consider
additional factors such as cash flow, economic conditions and developments in
the issuer's industry. Generally, the shares of a company in any given country
will be considered to have a high book to market ratio if the ratio equals or
exceeds the ratios of any of the 30% of companies in that country with the
highest positive book to market ratios whose shares are listed on a major
exchange, and, except as described below, will be considered eligible for
investment. The International Value Series intends to invest in the stocks of
large companies in countries with developed markets.
 
                                       30
<PAGE>
    Under normal market conditions, at least 65% of the International Value
Series' assets will be invested in companies organized or having a majority of
their assets in or deriving a majority of their operating income in at least
three non-U.S. countries, and no more than 40% of the Series' assets will be
invested in such companies in any one country. The International Value Series
reserves the right to invest in index futures contracts to commit funds awaiting
investment or to maintain liquidity. To the extent that the International Value
Series invests in futures contracts for other than bona fide hedging purposes,
the Series will not purchase futures contracts if as a result more than 5% of
its net assets would then consist of initial margin deposits required to
establish such contracts.
 
    As of the date of this prospectus, the International Value Series intends to
invest in companies having at least $800 million of market capitalization, and
the Series will be approximately market capitalization weighted. The Advisor may
reset such floor from time to time to reflect changing market conditions. In
determining market capitalization weights, the Advisor, using its best judgment,
will seek to eliminate the effect of cross holdings on the individual country
weights. As a result, the weighting of certain countries in the International
Value Series may vary from their weighting in international indices such as
those published by The Financial Times, Morgan Stanley Capital International or
Salomon/Russell. The Advisor, however, will not attempt to account for cross
holding within the same country.
 
    It is management's belief that the value stocks of large companies, over a
long term, a prudent opportunity for capital appreciation, but, at the same
time, selecting a limited number of such issues for inclusion in the
International Value Series involves greater risk than including a large number
of them. The Advisor does not anticipate that a significant number of securities
which meet the market capitalization criteria will be selectively excluded from
the International Value Series.
 
    The International Value Series does not seek current income as an investment
objective and investments will not be based upon an issuer's dividend payment
policy or record. However, many of the companies whose securities will be
included in the International Value Series do pay dividends. It is anticipated,
therefore, that the International Value Series will receive dividend income.
 
                 TAX-MANAGED DFA INTERNATIONAL VALUE PORTFOLIO
 
INVESTMENT OBJECTIVE AND POLICIES
 
    The Tax-Managed DFA International Value Portfolio has the same investment
objective as, and investment policies that are similar to, the DFA International
Value Series. (See DFA INTERNATIONAL VALUE PORTFOLIO--Investment Objective and
Policies" above.) However, the Advisor will manage its portfolio in a manner
that will seek to defer the realization of net capital gains and may minimize
the receipt of dividend income in order to minimize taxable distributions to
investors. These tax management strategies may, from time to time, cause
deviation from market capitalization weightings. The Tax-Managed DFA
International Value Portfolio should not be expected to adhere to its market
capitalization weightings with the same precision as the other Master Funds and
Portfolios. In addition, the investment policies of the Tax-Managed DFA
International Value Portfolio, including its portfolio structure and
transactions, differ slightly from the DFA International Value Portfolio. (For
additional information regarding the investment policies applicable to the
Tax-Managed DFA International Value Portfolio, see "TAX MANAGEMENT STRATEGIES"
below.)
 
                     INTERNATIONAL SMALL COMPANY PORTFOLIOS
 
INVESTMENT OBJECTIVES AND POLICIES
 
    The International Small Company Portfolio, and the Japanese Small Company,
Pacific Rim Small Company, United Kingdom Small Company and Continental Small
Company Series of the Trust (the latter four being referred to hereinafter as
the "International Small Company Master Funds") each have an
 
                                       31
<PAGE>
investment objective to achieve long-term capital appreciation. The
International Small Company Portfolios provide investors with access to
securities portfolios consisting of small Japanese, United Kingdom, European and
Pacific Rim companies. Company size will be determined for purposes of these
Portfolios and Master Funds solely on the basis of a company's market
capitalization which will be calculated by multiplying the number of outstanding
shares of the company that are similar to domestic common stocks by the price of
the company's stock.
 
    Each International Small Company Master Fund intends to invest at least 80%
of its assets in equity securities of its targeted country or region of the
world. The International Small Company Master Funds will be structured to
reflect reasonably the relative market capitalizations of their portfolio
companies. The Advisor believes that over the long term the investment
performance of small companies is superior to large companies and that
investment in the Portfolios is an effective way to improve global
diversification. Investors which, for a variety of reasons, may choose not to
make substantial, or any, direct investment in companies whose securities will
be held by the International Small Company Master Funds, may participate in the
investment performance of these companies through ownership of a Portfolio's
stock.
 
INTERNATIONAL SMALL COMPANY PORTFOLIO
 
    The International Small Company Portfolio seeks to achieve its investment
objective by investing virtually all of its assets in up to four International
Small Company Master Funds in such relative portions as determined by the
Advisor from time to time. For a complete description of the investment
objectives and policies, portfolio structure and transactions for each
International Small Company Master Fund, see "INTERNATIONAL SMALL COMPANY
PORTFOLIOS--INVESTMENT OBJECTIVES AND POLICIES." The International Small Company
Portfolio is designed for investors who wish to achieve their investment
objective of capital appreciation by participating in the investment performance
of a broad range of equity securities of Japanese, United Kingdom, European and
Pacific Rim small companies.
 
    As of the date of this prospectus, the International Small Company Portfolio
invests in the shares of the International Small Company Master Funds within the
following percentage ranges:

Continental Small Company...............................................          20-45%
</TABLE>
 
    The allocation of the assets of International Small Company Portfolio to be
invested in the International Small Company Master Funds will be determined by
the Advisor on at least a semiannual basis. In setting the target allocation,
the Advisor will first consider the market capitalizations of all eligible
companies in each of the International Small Company Master Funds. The Advisor
will calculate the market capitalizations for each International Small Company
Master Fund in the manner described under INTERNATIONAL SMALL COMPANY
PORTFOLIOS--INVESTMENT OBJECTIVES AND POLICIES." In determining the target
allocations, the Advisor, using its best judgment, will seek to eliminate the
effect of cross holdings between companies on a portfolio by portfolio basis and
may take into account the existence of substantial private or government
ownership of the shares of a company. The Advisor may also consider such other
factors as it deems appropriate with respect to determining the target
allocations. The Advisor expects to change the relative weights ascribed to each
International Small Company Master Fund, based on its updated market
capitalization calculations, when it determines that fundamental changes in the
relative values ascribed by market forces to each relevant geographic area have
occurred. To maintain target weights during the period, adjustments may be made
by applying future purchases by International Small Company Portfolio in
proportion necessary to rebalance the investment portfolio of the Portfolio. As
of September 10, 1998, the International Small Company Portfolio discontinued
further investment in the Pacific Rim Master Fund as a consequence of certain
restrictions imposed by the
 
                                       32
<PAGE>
Malaysian government on the repatriation of assets by foreign investors, such as
the International Small Company Portfolio. Under normal conditions, the target
allocations for investment by the Portfolio in the International Small Company
Master Fund are: Japanese Small Company Series--25%; United Kingdom Small
Company Series--20%; Continental Small Company Series--40%; and Pacific Rim
Small Company Series--15%. As of the date of this prospectus, the target
allocations noted above do not reflect current allocations because the Portfolio
is not investing in the Pacific Rim Small Master Fund.
 
JAPANESE SMALL COMPANY PORTFOLIO
 
    Japanese Small Company Portfolio invests all of its assets in the Japanese
Small Company Series of the Trust (the "Japanese Series"), which has the same
investment objective and policies as the Portfolio. The Japanese Series will
invest in a broad and diverse group of readily marketable stocks of Japanese
small companies which are traded in the Japanese securities markets. Generally,
reference in this prospectus to the term "Japanese small company" means a
company located in Japan whose market capitalization is not larger than the
largest of those in the smaller one-half (deciles 6 through 10) of companies
whose securities are listed on the First Section of the Tokyo Stock Exchange
("TSE").
 
    While the Japanese Series will invest primarily in the stocks of small
companies which are listed on the TSE, it may acquire the stocks of Japanese
small companies which are traded in other Japanese securities markets as well.
It is the intention of the Japanese Series to acquire a portion of the stock of
each of these companies on a market capitalization weighted basis. (See "SMALL
COMPANY MASTER FUNDS-- Portfolio Structure.")
 
PACIFIC RIM SMALL COMPANY PORTFOLIO
 
   
    Pacific Rim Small Company Portfolio invests all of its assets in the Pacific
Rim Small Company Series of the Trust (the "Pacific Rim Series"), which has the
same investment objective and policies as the Portfolio. The Pacific Rim Series
is authorized to invest in stocks of a broad and diverse group of small
companies located in Australia, New Zealand and Pacific Rim Asian countries
whose shares are traded principally on the securities markets located in those
countries. As of September 10, 1998, the Pacific Rim Small Company Portfolio
ceased offering its shares to new investors as a consequence of certain
restrictions imposed by the Malaysian government on the repatriation of assets
by foreign investors, such as the Pacific Rim Series.
    
 
   
    Company size will be determined by the Advisor in a manner that will compare
the market capitalizations of the companies in all countries in which the
Pacific Rim Series invests. The Advisor typically will use the appropriate
country indices of the Financial Times Actuaries World Index ("FTW") converted
to a common currency and aggregated, to define "small companies." Generally,
companies with publicly traded stock whose market capitalizations are not
greater than the largest of those in the smallest 30% of companies (8th, 9th and
10th deciles) listed in the FTW as combined for the countries in which the
Pacific Rim Series invests will be considered to be "small companies" and will
be eligible for purchase by the Pacific Rim Series.
    
 
    While the Advisor typically will use the aggregated FTW indices to determine
the maximum size of eligible portfolio companies, portfolio acquisitions will
not be limited to stocks listed on the FTW for any country. The Pacific Rim
Series does not intend to purchase shares of any company whose market
capitalization is less than $5,000,000. The Pacific Rim Series intends to
acquire a portion of the stock of each eligible company on a market
capitalization basis. (See "SMALL COMPANY MASTER FUNDS-- Portfolio Structure.")
 
UNITED KINGDOM SMALL COMPANY PORTFOLIO
 
    United Kingdom Small Company Portfolio invests all of its assets in the
United Kingdom Small Company Series of the Trust (the "United Kingdom Series"),
which has the same investment objective and
 
                                       33
<PAGE>
policies as the Portfolio. The United Kingdom Series will invest in a broad and
diverse group of readily marketable stocks of United Kingdom small companies
which are traded principally on the International Stock Exchange of the United
Kingdom and the Republic of Ireland ("ISE"). Generally, reference in this
prospectus to a "United Kingdom small company" means a company organized in the
United Kingdom, with shares listed on the ISE whose market capitalization is not
larger than the largest of those in the smaller one-half (deciles 6 through 10)
of companies included in the Financial Times Actuaries All Share Index ("FTA").
 
    The FTA is an index of stocks traded on the ISE, which is similar to the S&P
500 Index, and is used by investment professionals in the United Kingdom for the
same purposes as investment professionals in the United States use the S&P 500
Index. While the FTA typically will be used by the United Kingdom Series to
determine the maximum market capitalization of any company whose stock the
Series will purchase, acquisitions by the United Kingdom Series will not be
limited to stocks which are included in the FTA. The United Kingdom Series will
not, however, purchase shares of any investment trust or of any company whose
market capitalization is less than $5,000,000.
 
    It is the intention of United Kingdom Series to acquire a portion of the
stock of each eligible company on a market capitalization basis. (See "SMALL
COMPANY MASTER FUNDS--Portfolio Structure.")
 
CONTINENTAL SMALL COMPANY PORTFOLIO
 
   
    Continental Small Company Portfolio invests all of its assets in the
Continental Small Company Series of the Trust (the "Continental Series"), which
has the same investment objective and policies as the Portfolio. The Continental
Series is authorized to invest in readily marketable stocks of a broad and
diverse group of small companies organized under the laws of certain European
countries (See the list of countries under "INTERNATIONAL PORTFOLIOS--Countries"
above.). Company size will be determined by the Advisor in a manner that will
compare the market capitalizations of companies in all countries in which the
Continental Series invests. The Advisor typically will use the appropriate
country indices of the FTW converted to a common currency, the U.S. dollar, and
aggregated to define "small companies." The FTW consists of a series of country
indices which contain generally the largest companies in the major industry
sectors in proportion to their market capitalization whose shares are available
for purchase by nonresident investors. Its constituents represent about 70% of
the total market capitalization of the respective markets. Generally, companies
with publicly traded stock whose market capitalizations are not greater than the
largest of those in the smallest 20% (9th and 10th deciles) of companies listed
in the FTW as combined for the countries in which the Continental Series invests
will be considered to be "small companies" and will be eligible for purchase by
the Continental Series.
    
 
    While the Advisor typically will use the aggregated FTW indices to determine
the maximum size of eligible portfolio companies, portfolio acquisitions will
not be limited to stocks listed on the FTW for any country. The Continental
Series does not intend, however, to purchase shares of any company whose market
capitalization is less than the equivalent of $5,000,000. The Continental Series
intends to acquire a portion of the stock of each eligible company on a market
capitalization basis. The Advisor may in its discretion either limit further
investments in a particular country or divest the Continental Series of holdings
in a particular country. (See SMALL COMPANY MASTER FUNDS--Portfolio Structure.")
 
                           SMALL COMPANY MASTER FUNDS
 
   
PORTFOLIO CONSTRUCTION
    
 
    Each U.S. Small Company Master Fund and International Small Company Master
Fund (collectively the "Small Company Master Funds") is market capitalization
weighted. That is, each security is generally purchased based on the issuer's
relative market capitalization. In this way, the amount of a particular security
owned by a Small Company Master Fund is keyed to that security's market
capitalization
 
                                       34
<PAGE>
compared to all securities eligible for purchase. The following discussion
applies to the investment policies of the Small Company Master Funds.
 
    The decision to include or exclude the shares of an issuer will be made on
the basis of such issuer's relative market capitalization determined by
reference to other companies located in the same country, except that with
respect to Continental and Pacific Rim Series, such determination shall be made
by reference to other companies located in all countries in which those Series
invest. Company size is measured in terms of local currencies in order to
eliminate the effect of variations in currency exchange rates, except that
Continental and Pacific Rim Series each will measure company size in terms of a
common currency. Even though a company's stock may meet the applicable market
capitalization criterion, it may not be purchased if (i) in the Advisor's
judgment, the issuer is in extreme financial difficulty, (ii) the issuer is
involved in a merger or consolidation or is the subject of an acquisition or
(iii) a significant portion of the issuer's securities are closely held.
Further, securities of real estate investment trusts will not be acquired
(except as part of a merger, consolidation or acquisition of assets.)
 
    If securities must be sold in order to obtain funds to make redemption
payments, such securities may be repurchased, as additional cash becomes
available. In most instances, however, management would anticipate selling
securities which had appreciated sufficiently to be eligible for sale and,
therefore, would not need to repurchase such securities. (See "SMALL COMPANY
MASTER FUNDS--Portfolio Transactions.")
 
    It is management's belief that the stocks of small companies offer, over a
long term, a prudent opportunity for capital appreciation, but, at the same
time, selecting a limited number of such issues for investment involves greater
risk than investing in a large number of them.
 
    Generally, current income is not sought as an investment objective and
investments will not be based upon an issuer's dividend payment policy or
record. However, many of the companies whose securities will be selected for
investment do pay dividends. It is anticipated, therefore, that dividend income
will be received.
 
   
    On a periodic basis, the Advisor will review the holdings of each Small
Company Master Fund and determine which, at the time of such review, are no
longer considered small U.S., Japanese, United Kingdom, European or Pacific Rim
companies. The present policy of the Advisor (except with respect to the 6-10
Series) is to consider portfolio securities for sale when they have appreciated
sufficiently to rank, on a market capitalization basis, more than one full
decile higher than the company with the largest market capitalization that is
eligible for purchase by the particular Small Company Master Fund as determined
periodically by the Advisor. The Advisor may, from time to time, revise that
policy if, in the opinion of the Advisor, such revision is necessary to maintain
appropriate market capitalization weighting.
    
 
                  DFA INTERNATIONAL SMALL CAP VALUE PORTFOLIO
 
INVESTMENT OBJECTIVES AND POLICIES
 
    The investment objective of the DFA International Small Cap Value Portfolio
is to achieve long-term capital appreciation. The Portfolio pursues its
objective by investing in the stocks of small non-U.S. companies that have a
high book to market ratio. The Investment Committee of the Advisor will
initially set the standards for determining whether the shares of a company in
any given country will be considered to be value stocks at the time of purchase.
Securities are considered value stocks primarily because a company's shares have
a high book to market ratio. Generally, such shares will be considered eligible
for investment. In measuring value, the Advisor may consider additional factors
such as cash flow, economic conditions and developments in the issuer's
industry. The Investment Committee will periodically review its standards for
determining high book to market value and will adjust the standards accordingly.
The Portfolio intends to invest in the stocks of small companies in countries
with developed markets. Under normal market conditions, at least 65% of the
Portfolio's assets will be invested in value stocks of small
 
                                       35
<PAGE>
   
companies, organized or having a majority of their assets in or deriving a
majority of their operating income in at least three non-U.S. countries. As of
the date of this prospectus, the Portfolio intends to invest in small companies
which, for purposes of this Portfolio, are defined as companies having no more
than $800 million of market capitalization. The Advisor may reset such ceiling
from time to time to reflect changing market conditions. The Advisor believes
that such maximum amount accounts for variations in company size among countries
and provides a sufficient universe of eligible companies. Currently no more than
40% of the Portfolio's assets is invested in such companies in any one country,
and if this changes, a supplement to this prospectus will disclose such change.
The Portfolio reserves the right to invest in index futures contracts to commit
funds awaiting investment or to maintain liquidity. To the extent that the
Portfolio invests in futures contracts for other than bona fide hedging
purposes, the Portfolio will not purchase futures contracts if as a result more
than 5% of its net assets would then consist of initial margin deposits required
to establish such contracts.
    
 
   
    The Portfolio will be approximately market capitalization weighted. In
determining market capitalization weights, the Advisor, using its best judgment,
will seek to eliminate the effect of cross holdings on the individual country
weights. As a result, the weighting of certain countries in the Portfolio may
vary from their weighting in international indices such as those published by
The Financial Times, Morgan Stanley Capital International or Salomon/Russell.
The Advisor, however, will not attempt to account for cross holding within the
same country.
    
 
    It is management's belief that the stocks of small companies with high book
to market ratios offer, over a long term, a prudent opportunity for capital
appreciation, but, at the same time, selecting a limited number of such issues
for inclusion in the Portfolio involves greater risk than including a large
number of them. The Advisor does not anticipate that a significant number of
securities which meet the market capitalization criteria will be selectively
excluded from the Portfolio.
 
    The Portfolio does not seek current income as an investment objective and
investments will not be based upon an issuer's dividend payment policy or
record. However, many of the companies whose securities will be included in the
Portfolio do pay dividends. It is anticipated, therefore, that the Portfolio
will receive dividend income.

                          EMERGING MARKETS PORTFOLIO,
                      EMERGING MARKETS VALUE PORTFOLIO AND
                      EMERGING MARKETS SMALL CAP PORTFOLIO
 
INVESTMENT OBJECTIVES AND POLICIES
 
   
    The investment objective of both the Emerging Markets Portfolio and the
Emerging Markets Small Cap Portfolio is to achieve long-term capital
appreciation. The Emerging Markets Portfolio invests all of its assets in the
Emerging Markets Series of the Trust (the "Emerging Markets Series"), which has
the same investment objective and policies as the Portfolio. The Emerging
Markets Small Cap Portfolio invests all of its assets in the Emerging Markets
Small Cap Series of the Trust (the "Emerging Markets Small Cap Series"), which
has the same investment objective and policies as the Portfolio. The investment
objective of the Dimensional Emerging Markets Value Fund Inc. ("Dimensional
Emerging Markets Value Fund") is to seek long-term capital growth through
investment primarily in emerging market equity securities. The Emerging Markets
Value Portfolio invests all of its assets in the Dimensional Emerging Markets
Value Fund, which has the same investment objective and policies as the
Portfolio. The Emerging Markets Series, the Emerging Markets Small Cap Series
and the Dimensional Emerging Markets Value Fund are referred to collectively as
the "Emerging Markets Master Funds." Each Emerging Markets Master Fund seeks to
achieve its investment objective by investing in emerging markets designated by
the Investment Committee of the Advisor ("Approved Markets"). (See the list of
countries under "INTERNATIONAL PORTFOLIOS--COUNTRIES" above.) Each Emerging
Markets Master Fund invests its assets primarily in Approved Market equity
securities listed on bona fide securities exchanges or actively traded on OTC
markets. These exchanges or OTC markets may be either within or outside the
issuer's domicile country, and the securities may be listed or traded in the
form of International Depository Receipts ("IDRs") or American Depository
Receipts ("ADRs").
    
 
EMERGING MARKETS MASTER FUNDS CHARACTERISTICS AND POLICIES
 
    The Emerging Markets Series of the Trust will seek a broad market coverage
of larger companies within each Approved Market. This Series will attempt to own
shares of companies whose aggregate overall share of the Approved Market's total
public market capitalization is at least in the upper 40% of such
capitalization, and can be as large as 75%. The Emerging Markets Series may
limit the market coverage in the smaller emerging markets in order to limit
purchases of small market capitalization companies.
 
    The Emerging Markets Small Cap Series of the Trust will seek a broad market
coverage of smaller companies within each Approved Market. This Series will
attempt to own shares of companies whose market capitalization is less than $1.5
billion. On a periodic basis, the Advisor will review the holdings of the
Emerging Markets Small Cap Series and determine which, at the time of such
review, are no longer considered small emerging market companies. The present
policy is to consider portfolio securities for sale when they have appreciated
sufficiently to rank, on a market capitalization basis, 100% larger than the
largest market capitalization that is eligible for purchase as set by the
Advisor for that Approved Market.
 
    The Dimensional Emerging Markets Value Fund seeks to achieve its objective
by investing in emerging market equity securities which are deemed by the
Advisor to be value stocks at the time of purchase. Securities are considered
value stocks primarily because they have a high book value in relation to their
market value. In measuring value, the Advisor may consider additional factors
such as cash flow, economic conditions and developments in the issuer's
industry.
 
    The Dimensional Emerging Markets Value Fund's policy is to seek to achieve
its investment objective by investing in emerging market equity securities
across all market capitalizations, and specifically those which are deemed by
the Advisor to be value stocks at the time of purchase, as described above.
 
                                       37
<PAGE>
    Each Emerging Markets Master Fund may not invest in all such companies or
Approved Markets described above or achieve approximate market weights, for
reasons which include constraints imposed within Approved Markets, restrictions
on purchases by foreigners, and each Emerging Markets Master Fund's policy not
to invest more than 25% of its assets in any one industry.
 
    Under normal market conditions, the Emerging Markets Series will invest at
least 65% of its assets in Approved Market securities; the Emerging Markets
Small Cap Series will invest at least 65% of its assets in small company (as
defined above) Approved Market securities; and the Dimensional Emerging Markets
Value Fund will invest at least 65% of its assets in Approved Market equity
securities that are deemed by the Advisor to be value stocks at the time of
purchase. Approved Market securities are defined to be (a) securities of
companies organized in a country in an Approved Market or for which the
principal trading market is in an Approved Market, (b) securities issued or
guaranteed by the government of an Approved Market country, its agencies or
instrumentalities, or the central bank of such country, (c) securities
denominated in an Approved Market currency issued by companies to finance
operations in Approved Markets, (d) securities of companies that derive at least
50% of their revenues primarily from either goods or services produced in
Approved Markets or sales made in Approved Markets and (e) Approved Markets
equity securities in the form of depositary shares. Securities of Approved
Markets may include securities of companies that have characteristics and
business relationships common to companies in other countries. As a result, the
value of the securities of such companies may reflect economic and market forces
in such other countries as well as in the Approved Markets. The Advisor,
however, will select only those companies which, in its view, have sufficiently
strong exposure to economic and market forces in Approved Markets such that
their value will tend to reflect developments in Approved Markets to a greater
extent than developments in other regions. For example, the Advisor may invest
in companies organized and located in the United States or other countries
outside of Approved Markets, including companies having their entire production
facilities outside of Approved Markets, when such companies meet the definition
of Approved Markets securities so long as the Advisor believes at the time of
investment that the value of the company's securities will reflect principally
conditions in Approved Markets.
 
   
    With respect to the Emerging Markets Series and Emerging Markets Small Cap
Series, the Advisor defines the term "emerging market" to mean a country which
is considered to be an emerging market by the International Finance Corporation.
In determining what countries have emerging markets with respect to the
Dimensional Emerging Markets Value Fund, the data, analysis and classification
of countries published or disseminated by the International Bank for
Reconstruction and Development (commonly known as the World Bank) and the
International Finance Corporation, among other things, will be considered.
Approved emerging markets may not include all such emerging markets. In
determining whether to approve markets for investment, the Advisor will take
into account, among other things, market liquidity, relative availability of
investor information, government regulation, including fiscal and foreign
exchange repatriation rules and the availability of other access to these
markets for the Emerging Markets Series, the Emerging Markets Small Cap Series
and the Dimensional Emerging Markets Value Fund.
    
 
    Each Emerging Markets Master Fund may invest up to 35% of its assets in
securities of issuers that are not Approved Markets securities, but whose
issuers the Advisor believes derive a substantial proportion, but less than 50%,
of their total revenues from either goods and services produced in, or sales
made in, Approved Markets.
 
    The Emerging Markets Master Funds also may invest up to 10% of their total
assets in shares of other investment companies that invest in one or more
Approved Markets, although they intend to do so only where access to those
markets is otherwise significantly limited. In some Approved Markets, it will be
necessary or advisable for an Emerging Markets Master Fund to establish a wholly
owned subsidiary or a trust for the purpose of investing in the local markets.
 
                                       38
<PAGE>
   
PORTFOLIO CONSTRUCTION
    
 
    The Emerging Markets Series' and Emerging Markets Small Cap Series' policy
of seeking broad market diversification means that the Advisor will not utilize
"fundamental" securities research techniques in identifying securities
selections. The decision to include or exclude the shares of an issuer will be
made primarily on the basis of such issuer's relative market capitalization
determined by reference to other companies located in the same country. Company
size is measured in terms of reference to other companies located in the same
country and in terms of local currencies in order to eliminate the effect of
variations in currency exchange rates.
 
   
    Even though a company's stock may meet the applicable market capitalization
criterion for a Series or the Dimensional Emerging Markets Value Fund's
criterion for investment, it may not be included in an Emerging Markets Master
Fund for one or more of a number of reasons. For example, in the Advisor's
judgment, the issuer may be considered in extreme financial difficulty, a
material portion of its securities may be closely held and not likely available
to support market liquidity, or the issuer may be a "passive foreign investment
company" (as defined in the Code). To this extent, there will be the exercise of
discretion and consideration by the Advisor which would not be present in the
management of a portfolio seeking to represent an established index of broadly
traded domestic securities (such as the S&P 500 Index). The Advisor will also
exercise discretion in determining the allocation of investments as between
Approved Markets.
    
 
    Changes in the composition and relative ranking (in terms of book to market
ratio) of the stocks which are eligible for purchase by the Dimensional Emerging
Markets Value Fund take place with every trade when the securities markets are
open for trading due primarily to price fluctuations of such securities. On a
periodic basis, the Advisor will prepare lists of eligible value stocks which
are eligible for investment. Such list will be revised no less than
semi-annually.
 
    It is management's belief that equity investments offer, over a long term, a
prudent opportunity for capital appreciation, but, at the same time, selecting a
limited number of such issues for inclusion in a Series involves greater risk
than including a large number of them.
 
    The Emerging Markets Master Funds do not seek current income as an
investment objective, and investments will not be based upon an issuer's
dividend payment policy or record. However, many of the companies whose
securities will be included in an Emerging Markets Master Fund do pay dividends.
It is anticipated, therefore, that the Emerging Markets Master Funds will
receive dividend income.
 
                            FIXED INCOME PORTFOLIOS
 
DFA ONE-YEAR FIXED INCOME PORTFOLIO
 
   
    The investment objective of DFA One-Year Fixed Income Portfolio is to
achieve a stable real return in excess of the rate of inflation with a minimum
of risk. The DFA One-Year Fixed Income Portfolio invests all of its assets in
the DFA One-Year Fixed Income Series of the Trust (the "One-Year Fixed Income
Series"), which has the same investment objective and policies as the Portfolio.
The One-Year Fixed Income Series will invest in U.S. government obligations,
U.S. government agency obligations, dollar-denominated obligations of foreign
issuers issued in the U.S., bank obligations, including U.S. subsidiaries and
branches of foreign banks, corporate obligations, commercial paper, repurchase
agreements and obligations of supranational organizations. Generally, the Series
will acquire obligations which mature within one year from the date of
settlement, but substantial investments may be made in obligations maturing
within two years from the date of settlement when greater returns are available.
It is the Series' policy that the weighted average length of maturity of
investments will not exceed one year. The Series principally invests in
certificates of deposit, commercial paper, bankers' acceptances, notes and
bonds. The Series may concentrate its investments in obligations of U.S. and
foreign banks and bank holding companies (see "Investments in the Banking
Industry").

<PAGE>
DFA TWO-YEAR GLOBAL FIXED INCOME PORTFOLIO
 
    The investment objective of DFA Two-Year Global Fixed Income Portfolio is to
maximize total returns consistent with preservation of capital. The DFA Two-Year
Global Fixed Income Portfolio invests all of its assets in the DFA Two-Year
Global Fixed Income Series of the Trust (the "Two-Year Global Fixed Income
Series"). The Two-Year Global Fixed Income Series will have the same investment
objective and policies as the Portfolio. The Two-Year Global Fixed Income Series
will invest in 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," 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 which are 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 Series will invest at least 65% of the value of
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.
 
    The Series will acquire obligations which mature within two years from the
date of settlement. Because many of the Series' investments will be denominated
in foreign currencies, the Series will also enter into forward foreign currency
contracts solely for the purpose of hedging against fluctuations in currency
exchange rates. The Series may concentrate its investments in obligations of
U.S. and foreign banks and bank holding companies (see "Investment in the
Banking Industry").
 
DFA FIVE-YEAR GOVERNMENT PORTFOLIO
 
    The investment objective of DFA Five-Year Government Portfolio is to
maximize total returns available from the universe of debt obligations of the
U.S. government and U.S. government agencies. Ordinarily, the Portfolio will
invest at least 65% of its assets in U.S. government obligations and U.S.
government agency obligations that mature within five years from the date of
settlement. The Portfolio will also acquire repurchase agreements.
 
DFA FIVE-YEAR GLOBAL FIXED INCOME PORTFOLIO
 
   
    The investment objective of DFA Five-Year Global Fixed Income Portfolio is
to provide a market rate of return for a fixed income portfolio with low
relative volatility of returns. The Portfolio will invest primarily in
obligations issued or guaranteed by the U.S. and foreign governments, their
agencies and instrumentalities, obligations of other foreign issuers rated AA or
better, corporate debt obligations, bank obligations, commercial paper rated as
set forth in "Description of Investments" and 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 which are
developed countries, such as those countries which are members of the OECD.
However, in the future, the Advisor anticipates investing in issuers located in
other countries as well. Under normal market conditions, the Portfolio will
invest at least 65% of the value of 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.
The Portfolio will invest at least 65% of its assets in obligations which mature
within five years from the date of settlement. Because many of the Portfolio's
investments will be denominated in foreign currencies, the Portfolio will also
enter into forward foreign currency contracts solely for the purpose of hedging
against fluctuations in currency exchange rates.

<PAGE>
DFA INTERMEDIATE GOVERNMENT FIXED INCOME PORTFOLIO
 
    The investment objective of DFA Intermediate Government Fixed Income
Portfolio is to earn current income consistent with preservation of capital.
Ordinarily, the Portfolio will invest at least 65% of its assets in non-callable
obligations issued or guaranteed by the U.S. government and U.S. government
agencies, AAA rated, dollar-denominated obligations of foreign governments,
obligations of supranational organizations, and futures contracts on U.S.
Treasury securities. Since government guaranteed mortgage backed securities are
considered callable, such securities will not be included in the Portfolio.
 
    Generally, the Portfolio will purchase securities with maturities of between
five and fifteen years. The Portfolio will not shift the maturity of its
investments in anticipation of interest rate movements and ordinarily will have
an average weighted maturity, based upon market values, of between seven to ten
years. One of the benefits of the Portfolio is expected to be that in a period
of steeply falling interest rates, the Portfolio should perform well because of
its average weighted maturity and the high quality and non-callable nature of
its investments. The Portfolio is expected to match or exceed the returns of the
Lehman Brothers Treasury Index, without exceeding the volatility of that Index.
 
    The Portfolio may invest more than 5% of its assets in the obligations of
foreign governments. Those obligations at the time of purchase must be either
rated in the highest rating category of a nationally recognized statistical
rating organization or, in the case of any obligation that is unrated, of
comparable quality. The Portfolio also may invest in futures contracts on U.S.
Treasury securities or options on such contracts for the purposes of remaining
fully invested and maintaining liquidity to pay redemptions. However, the
Portfolio will not purchase futures contracts or options thereon if as a result
more than 5% of its net assets would then consist of initial margin deposits and
premiums required to establish such positions.

    1.  U.S. GOVERNMENT OBLIGATIONS--Debt securities issued by the U.S. Treasury
which 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, including the
Federal National Mortgage Association, Federal Home Loan Bank and the Federal
Housing Administration.
 
    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 Investors Services, Inc. ("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.
 
                                       41
<PAGE>
    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 not rated, issued by a corporation having an
outstanding unsecured debt issue rated AAA by Moody's or AAA by S&P, and having
a maximum maturity of nine months.
 
    6.  REPURCHASE AGREEMENTS--Instruments through which the Portfolios purchase
securities ("underlying securities") from a bank, or a registered U.S.
government securities dealer, with an agreement by the seller to repurchase the
security 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 Portfolios 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 Portfolios will
also 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.
 
    The categories of investments that may be acquired by each of the Fixed
Income Portfolios (other than DFA Intermediate Government Fixed Income
Portfolio) and the One-Year Fixed Income and Two-Year Global Fixed Income Series
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 One-Year Fixed Income Series and Two-Year Global Fixed Income Series
will invest more than 25% of their total respective assets in obligations of
U.S. and foreign banks and bank holding companies when the yield to maturity on
these investments exceeds the yield to maturity on all other eligible portfolio
investments for a period of five consecutive days when the NYSE is open for
trading. The Feeder Portfolios that invest in the above Master Funds, the DFA
One-Year Fixed Income Portfolio and DFA Two-Year Global Fixed Income Portfolio,
each have the same policy. This policy can only be changed by a vote of
shareholders. Investments in the Master Funds will not be considered investments
in the banking industry so that a Feeder Portfolio may invest all or
substantially all of its assets in its respective Master Fund. When investment
in such obligations exceeds 25% of the total net assets of any of these Master
Funds, such Master Fund will be considered to be concentrating its investments
in the banking industry. As of the date of this prospectus, (i) the One-Year
Fixed Income Series is not concentrating its investment in this industry and
(ii) the Two-Year Global Fixed Income Series is concentrating its investment in
this industry.

<PAGE>
    The types of bank and bank holding company obligations in which the One-Year
Fixed Income Series and DFA Two-Year Global Fixed Income Series may invest
include: dollar-denominated certificates of deposit, bankers' acceptances,
commercial paper and other debt obligations issued in the United States and
which mature within two years of the date of settlement, provided such
obligations meet each Series' established credit rating criteria as stated under
"Description of Investments." In addition, both Series are authorized to invest
more than 25% of their total assets in Treasury bonds, bills and notes and
obligations of federal agencies and instrumentalities.
 
PORTFOLIO STRATEGY
 
   
    The One-Year Fixed Income Series and Two-Year Global Fixed Income Series
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 Series will be chosen with a view to maximizing anticipated returns, net
of trading costs.
    
 
    The One-Year Fixed Income Series, Two-Year Global Fixed Income Series and
DFA Five-Year Government Portfolio are expected to have high portfolio turnover
rates due to the relatively short maturities of the securities to be acquired.
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. It is anticipated that the annual turnover rate of the Two-Year
Global Fixed Income Series, could be 0% to 200%. While the Fixed Income
Portfolios, the One-Year Fixed Income Series and Two-Year Global Fixed Income
Series acquire securities in principal transactions and, therefore, do 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, as stated above, securities ordinarily will be sold
when, in the Advisor's judgment, the monthly return of a Portfolio, the One-Year
Fixed Income Series or the Two-Year Fixed Income Series will be increased as a
result of portfolio transactions after taking into account the cost of trading.
It is anticipated that securities will be acquired in the secondary markets for
short term instruments.
 
    The DFA Five-Year Global Fixed Income Portfolio will be managed with a view
to capturing maturity risk premiums. Ordinarily the Portfolio will invest
primarily in obligations issued or guaranteed by foreign governments and their
agencies and instrumentalities, obligations of other foreign issuers rated AA or
better and supranational organizations. Supranational issuers include the
European Economic Community, the European Coal and Steel Community, the Nordic
Investment Bank, the World Bank and the Japanese Development Bank. The Portfolio
will own obligations issued or guaranteed by the U.S. government and its
agencies and instrumentalities also. At times when, in the Advisor's judgement,
eligible foreign securities do not offer maturity risk premiums that compare
favorably with those offered by eligible U.S. securities, the Portfolio will be
invested primarily in the latter securities.
 
                           TAX MANAGEMENT STRATEGIES
 
    The Tax-Managed U.S. 6-10 Small Company Portfolio, Tax-Managed Marketwide
Value Series, Tax-Managed U.S. 5-10 Value Portfolio and Tax-Managed DFA
International Value Portfolio (individually, a "Tax-Managed Portfolio or Series"
and collectively, the "Tax-Managed Portfolios and Series") seek to minimize the
impact of federal taxes on returns by managing their portfolios in a manner that
will defer the realization of net capital gains where possible and may minimize
dividend income.
 
                                       43
<PAGE>
    When selling securities, each Tax-Managed Portfolio or Series typically will
select the highest cost shares of the specific security in order to minimize the
realization of capital gains. In certain cases, the highest cost shares may
produce a short-term capital gain. Since short-term capital gains are taxed at
higher tax rates than long-term capital gains, the highest cost shares with a
long-term holding period may be disposed of instead. Each Tax-Managed Portfolio
or Series may, when consistent with all other tax management policies, sell
securities in order to realize capital losses. Realized capital losses can be
used to offset realized capital gains, thus reducing capital gains
distributions. However, realization of capital gains is not entirely within the
Advisor's control. Capital gains distributions may vary considerably from year
to year; there will be no capital gains distributions in years when a
Tax-Managed Portfolio or Series realizes net capital losses. The timing of
purchases and sales of securities may be managed to minimize the receipt of
dividends to the extent possible. With respect to dividends that are received,
the Tax-Managed Portfolios and Series may not be eligible to flow through the
dividends received deduction attributable to holdings in U.S. equity securities
to corporate shareholders, if because of timing activities, the requisite
holding period of the dividend paying stock is not met. Portfolio holdings may
be managed to emphasize low dividend-yielding securities.
 
    The Tax-Managed Portfolios and Series are expected to deviate from their
market capitalization weightings to a greater extent than the other Portfolios
and Master Funds. For example, the Advisor may exclude the stock of a company
that meets applicable market capitalization criteria in order to avoid dividend
income, and the Advisor may sell stock of a company that meets applicable market
capitalization criteria in order to realize a capital loss. Additionally, while
the non-Tax-Managed Portfolios and Series are managed so that securities will
generally be held for longer than one year, the Tax-Managed Portfolios and
Series may dispose of any securities whenever the Advisor determines that such
disposition would be consistent with the tax management strategies of the
Tax-Managed Portfolios and Series.
 
    Although the Advisor seeks to manage each Tax-Managed Portfolio or Series in
order to minimize the realization of capital gains and possible taxable dividend
income during a particular year, the Tax-Managed Portfolio or Series may
nonetheless distribute taxable gains and taxable income to shareholders from
time to time. Furthermore, shareholders may be required to pay taxes on a
Tax-Managed Portfolio's or Series' capital gains, if any, realized upon the sale
of the Tax-Managed Portfolio's or Series' assets to meet redemptions of shares
of the Tax-Managed Portfolio or Series. The redeeming shareholder will be
required to pay taxes on the shareholder's capital gains realized on a
redemption, whether paid in cash or in kind, if the amount realized on
redemption is greater than the amount the shareholder paid for the shares of the
Tax-Managed Portfolio or Series.
 
   
                               PORTFOLIO TURNOVER
    
 
   
    The Enhanced U.S. Large Company and DFA Two-Year Global Fixed Income
Portfolios engage in frequent trading of portfolio securities. A high portfolio
turnover rate may have negative tax consequences to shareholders and may result
in increased trading costs.
    
 
                     PORTFOLIO TRANSACTIONS--ALL PORTFOLIOS
 
    With respect to all Domestic and International Equity Portfolios and the
Master Funds in which such Portfolios might invest, investments will generally
be made in eligible securities on a market capitalization weighted basis.
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 which 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.
 
                                       44
<PAGE>
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 considered an appropriate holding in light of the investment policy of
each Portfolio.
 
                                SECURITIES LOANS
 
    All of the Portfolios and Master Funds are authorized to lend securities to
qualified brokers, dealers, banks and other financial institutions for the
purpose of earning additional income, although inasmuch as the Feeder Portfolios
will only hold shares of a corresponding Master Fund, these Portfolios do not
intend to lend those shares. While a Portfolio or Master Fund may earn
additional income from lending securities, such activity is incidental to the
investment objective of a Portfolio or Master Fund. The value of securities
loaned may not exceed 33 1/3% of the value of a Portfolio's or Master Fund's
total assets. In connection with such loans, a Portfolio or Series will receive
collateral consisting of cash or U.S. government securities, which will be
maintained at all times in an amount equal to at least 100% of the current
market value of the loaned securities. In addition, the Portfolios and Master
Funds 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. In the event of the bankruptcy of
the borrower, the Funds or the Trust could experience delay in recovering the
loaned securities. Management believes that this risk can be controlled through
careful monitoring procedures.
 
                 DEVIATION FROM MARKET CAPITALIZATION WEIGHTING
 
   
    The portfolio structures of each Small Company Master Fund, the Large Cap
International Portfolio, the DFA Real Estate Securities Portfolio, each Value
Master Fund, the International Value Series, the DFA International Small Cap
Value Portfolio and the Tax-Managed Portfolios and Series involve market
capitalization weighting. That is, their investment portfolios are market
capitalization weighted. Deviation from strict market capitalization weighting
may occur for several reasons. The Advisor may exclude the stock of a company
that meets applicable market capitalization criterion if the Advisor determines
in its best judgment that the purchase of such stock is inappropriate given
other conditions. The Advisor does not anticipate that a significant number of
securities that meet the market capitalization criteria will be selectively
excluded from the Large Cap International Portfolio. Deviation also will occur
because the Advisor intends to purchase in round lots only. Furthermore, the
Advisor may reduce the relative amount of any security held from the level of
strict adherence to market capitalization weighting, in order to retain
sufficient portfolio liquidity. A portion, but generally not in excess of 20% of
assets may be invested in interest bearing obligations, such as money market
instruments, thereby causing further deviation from strict market capitalization
weighting. A further deviation may occur due to investments in privately placed
convertible debentures. Finally, the tax management strategies undertaken by the
Tax-Managed Portfolios and Series may cause deviation from market capitalization
weighting.
    
 
    Block purchases of eligible securities may be made at opportune prices even
though such purchases exceed the number of shares which, at the time of
purchase, strict adherence to the policy of market capitalization weighting
would otherwise require. (The 4-10 Value Series intends to purchase common
stocks in the 9th and 10th deciles through block trades only.) In addition,
securities eligible for purchase or otherwise represented in a portfolio may be
acquired in exchange for the issuance of shares. (See "PURCHASE OF SHARES--In
Kind Purchases.") While such transactions might cause a temporary deviation from
market capitalization weighting, they would ordinarily be made in anticipation
of further growth of assets.
 
    Changes in the composition and relative ranking (in terms of market
capitalization) of the stocks which are eligible for purchase take place with
every trade when the securities markets are open for trading due, primarily, to
price fluctuations of such securities. On at least a semi-annual basis, the
Advisor will prepare lists of companies eligible for investment by a portfolio.
Additional investments generally will not be made in securities which have
changed in value sufficiently to be excluded from the Advisor's then
 
                                       45
<PAGE>
current market capitalization requirement for eligible portfolio securities.
This may result in further deviation from strict market capitalization
weighting. Such deviation could be substantial if a significant amount of a
portfolio's holdings change in value sufficiently to be excluded from the
requirement for eligible securities, but not by a sufficient amount to warrant
their sale.
 
                            MANAGEMENT OF THE FUNDS
 
    Dimensional Fund Advisors Inc. (the "Advisor") serves as investment advisor
to each of the Portfolios, except the Feeder Portfolios, and each Master Fund.
As such, the Advisor is responsible for the management of their respective
assets. Investment decisions for all non-feeder Portfolios and all Master Funds
are made by the Investment Committee of the Advisor which meets on a regular
basis and also as needed to consider investment issues. The Investment Committee
is composed of certain officers and directors of the Advisor who are elected
annually. The Advisor provides the Portfolios (except the Feeder Portfolios and
International Small Company Portfolio) and the Master Funds and International
Master Funds with a trading department and selects brokers and dealers to effect
securities transactions. Securities transactions are placed with a view to
obtaining best price and execution. The Advisor's address is 1299 Ocean Avenue,
11th Floor, Santa Monica, CA 90401. For advisory fees that the Portfolios have
incurred for the fiscal year ended November 30, 1998, see "ANNUAL FUND OPERATING
EXPENSES."
 
    The Funds and the Master Funds bear all of their own costs and expenses,
including: services of their independent accountants, 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 their shareholders and directors or trustees, the cost of filing
their registration statements under the federal securities laws and the cost of
any filings required under state securities laws, reports to shareholders, and
transfer and dividend disbursing agency, administrative services and custodian
fees, except as described above with respect to waivers or reductions and with
respect to the U.S. Large Company Portfolio. Expenses allocable to a particular
Portfolio or Master Fund are so allocated. The expenses of a Fund which are not
allocable to a particular Portfolio are to be borne by each Portfolio of the
Fund on the basis of its relative net assets. Similarly, the expenses of the
Trust which are not allocable to a particular Series are to be borne by each
Master Fund on the basis of its relative net assets.
 
    The Advisor was organized in May 1981 and is engaged in the business of
providing investment management services to institutional investors. Assets
under management total approximately $28 billion. The Advisor owns 100% of the
outstanding shares of Dimensional Fund Advisors Ltd. ("DFAL") (see "Investment
Services--United Kingdom and Continental Small Company Series") and beneficially
owns 100% of DFA Australia Limited ("DFA Australia") (see "Investment
Services--Japanese and Pacific Rim Small Company Series").
 
INVESTMENT SERVICES--JAPANESE AND PACIFIC RIM SMALL COMPANY SERIES
 
    Pursuant to Sub Advisory Agreements with the Advisor, DFA Australia, Suite
2001, Level 20 Gateway, 1 MacQuarie Place, Sydney, New South Wales 2000,
Australia, the successor to Dimensional Fund Advisors Asia Inc., has the
authority and responsibility to select brokers and dealers to execute securities
transactions for Japanese and Pacific Rim Small Company Series. DFA Australia's
duties include the maintenance of a trading desk for each Series and the
determination of the best and most efficient means of executing securities
transactions. On at least a semiannual basis, the Advisor reviews the holdings
of Japanese and Pacific Rim Small Company Series and reviews the trading process
and the execution of securities transactions. The Advisor is responsible for
determining those securities which are eligible for purchase and sale by these
Series and may delegate this task, subject to its own review, to DFA Australia.
DFA Australia maintains and furnishes to the Advisor information and reports on
Japanese and Pacific Rim small companies, including its recommendations of
securities to be added to the securities that are eligible for purchase by each
Series.

CONSULTING SERVICES--LARGE CAP INTERNATIONAL PORTFOLIO, DFA INTERNATIONAL VALUE
  SERIES, TAX-MANAGED DFA INTERNATIONAL VALUE SERIES, DFA INTERNATIONAL SMALL
  CAP VALUE PORTFOLIO, EMERGING MARKETS SERIES, EMERGING MARKETS SMALL CAP
  SERIES AND DIMENSIONAL EMERGING MARKETS VALUE FUND
 
    The Advisor has entered into a Consulting Services Agreement with DFAL and
DFA Australia, respectively. Pursuant to the terms of each Consulting Services
Agreement, DFAL and DFA Australia provide certain trading and administrative
services to the Advisor with respect to DFA International Small Cap Value
Portfolio, Large Cap International Portfolio, DFA International Value Series,
Tax-Managed DFA International Value Series, Emerging Markets Series, Emerging
Markets Small Cap Series and Dimensional Emerging Markets Value Fund.
 
                DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES
 
    The policy of the Domestic and International Equity Portfolios, except U.S.
Large Company Portfolio, Enhanced U.S. Large Company Portfolio, U.S. Large Cap
Value Portfolio, Tax-Managed U.S. Marketwide Value Portfolio and DFA
International Value Portfolio is to distribute substantially all of their net
investment income together with any net realized capital gains in December of
each year. Dividends from net investment income of U.S. Large Company Portfolio,
Enhanced U.S. Large Company Portfolio, U.S. Large Cap Value Portfolio,
Tax-Managed U.S. Marketwide Value Portfolio and DFA International Value
Portfolio are distributed quarterly and any net realized capital gains are
distributed annually after November 30. Net investment income, which is accrued
daily, will be distributed monthly (except for January) by DFA One-Year Fixed
Income Portfolio, quarterly by DFA Intermediate Government Fixed Income, DFA
Two-Year Global Fixed Income and DFA Five-Year Global Fixed Income Portfolios,
and semiannually by DFA Five-Year Government Portfolio. Any net realized capital
gains of the Fixed Income Portfolios will be distributed annually after the end
of the fiscal year.
 
   
    Shareholders of each of the Portfolios 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 as to U.S. 9-10 Small Company Portfolio, U.S. 6-10
Small Company Portfolio, Tax-Managed U.S. 6-10 Small Company Portfolio, the
Fixed Income Portfolios, DFA Real Estate Securities Portfolio, U.S. Large
Company Portfolio, and the U.S. Value Portfolios upon written notice to PFPC,
the shareholder selects one of the options listed below. While shareholders of
the Enhanced U.S. Large Company Portfolio will automatically receive all capital
gains distributions in additional shares of the Portfolio, upon written notice
to PFPC, they may receive all income dividends in cash.
    
 
                                       47
<PAGE>
       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.
 
    Certain investments by the Portfolios (or their corresponding Master Fund)
may be subject to special rules which may affect the amount, character and
timing of the income to the investing entity. Some of these rules are referenced
in the statement of additional information. Specifically, prospective investors
should consult the statement of additional information for further information
regarding the extent to which distributions from a Portfolio may be eligible for
the dividends received deduction or whether certain foreign tax credits may be
available to an investor in a Portfolio.
 
    Whether paid in cash or additional shares and regardless of the length of
time a Portfolio's shares have been owned by shareholders who are subject to
U.S. federal income taxes, distributions from long-term capital gains are
taxable as such. Dividends from net investment income or net short-term capital
gains will be taxable as ordinary income, whether received in cash or in
additional shares. For those investors subject to tax, if purchases of shares of
a Portfolio are made shortly before the record date for a dividend or capital
gains distribution, a portion of the investment will be returned as a taxable
distribution. Shareholders are notified annually by the Funds as to the U.S.
federal tax status of dividends and distributions paid by the Portfolio whose
shares they own.
 
    Dividends which are declared in October, November or December to
shareholders of record in such a month, but which, for operational reasons, may
not be paid to the shareholder until the following January, will be treated for
U.S. federal income tax purposes as if paid by the Portfolio and received by the
shareholder on December 31 of the calendar year in which they are declared.
 
    The sale of shares of a Portfolio is a taxable event and may result in a
capital gain or loss to shareholders subject to tax. Capital gain or loss may be
realized from an ordinary redemption of shares or an exchange of shares between
two Portfolios. Any loss incurred on 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.
 
    In addition to federal taxes, shareholders may be subject to state and local
taxes on distributions and on sales of shares of a Portfolio. Distributions of
interest income and capital gains realized from certain types of U.S. government
securities may be exempt from state personal income taxes.
 
    A Portfolio is required to withhold 31% of taxable dividends, capital gains
distributions, and redemptions paid to shareholders who have not complied with
IRS taxpayer identification regulations. You may avoid this withholding
requirement by certifying on the account registration form your proper Taxpayer
Identification Number and by certifying that you are not subject to backup
withholding.
 
    The tax discussion set forth above is included for general information only.
Prospective investors should consult the statement of additional information.
Prospective investors should also consult their own tax advisers concerning the
federal, state, local or foreign tax consequences of an investment in a
Portfolio.
 
                               PURCHASE OF SHARES
 
CASH PURCHASES
 
    Investors may purchase shares of any Portfolio by first contacting the
Advisor at (310) 395-8005 to notify the Advisor of the proposed investment. 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
Funds
 
                                       48
<PAGE>
reserve the right to reject any initial or additional investment and to suspend
the offering of shares of any Portfolio.
 
    "Good order" with respect to the purchase of shares means that (1) a fully
completed and properly signed Account Registration Form and any additional
supporting legal documentation required by the Advisor has 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 (ordinarily 1:00 p.m. PST) on the day of the
purchase. If an order to purchase shares must be canceled due to nonpayment, the
purchaser will be responsible for any loss incurred by a Fund arising out of
such cancellation. To recover any such loss, the Funds reserve the right to
redeem shares owned by any purchaser whose order is canceled, and such purchaser
may be prohibited or restricted in the manner of placing further orders.
 
    Investors having an account with a bank that is a member or a correspondent
of a member of the Federal Reserve System may purchase shares by first calling
the Advisor at (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) or, with regard to purchases of the DFA International
Value Portfolio, for the account of Dimensional Investment Group Inc. (DFA
International Value Portfolio). Additional investments also may be made through
the wire procedure by first notifying the Advisor. Investors who wish to
purchase shares of any Portfolio (other than the DFA International Value
Portfolio) by check should send their check to DFA Investment Dimensions Group
Inc., c/o PFPC Inc., 400 Bellevue Parkway, Wilmington, Delaware 19809. To
purchase shares of the DFA International Value Portfolio investors should send
their check to Dimensional Investment Group Inc., c/o PFPC Inc., at the above
address.
 
    Payment of the total amount due should be made in U.S. dollars. 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 may also be purchased and sold by individuals through securities
firms which may charge a service fee or commission for such transactions. No
such fee or commission is charged on shares which are purchased or redeemed
directly from the Funds. 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 Funds, shares of the Portfolios may be purchased in
exchange for securities which are eligible for acquisition by the Portfolios (or
their corresponding Master Funds) or otherwise represented in their portfolios
as described in this prospectus or in exchange for local currencies in which
such securities of the International Equity Portfolios, the International Value
Series, Enhanced U.S. Large Company Series, DFA Two-Year Global Fixed Income
Series and DFA Five-Year Global Fixed Income Portfolio are denominated.
Purchases in exchange for securities will not be subject to a reimbursement fee.
Securities and local currencies to be exchanged which are accepted by the Funds
and Fund shares to be issued therefore will be valued as set forth under
"VALUATION OF SHARES" at the time of the next determination of net asset value
after such acceptance. All dividends, interest, subscription, or other rights
pertaining to such securities shall become the property of the Portfolio whose
shares are being acquired and must be delivered to the Fund by the investor upon
receipt from the issuer. Investors who desire to purchase shares of the
International Equity Portfolios, DFA Two-Year Global Fixed Income Portfolio or
DFA Five-Year Global Fixed Income Portfolio with local currencies should first
contact the Advisor for wire instructions.
 
                                       49
<PAGE>
    The Funds 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 whose shares are to be
issued (or in its corresponding Master Fund) 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 respective 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 or Master Fund may
not exceed 5% of the net assets of the Portfolio or Master Fund immediately
after the transaction, however, this last limitation does not apply to DFA
Five-Year Global Fixed Income Portfolio or the International Small Company
Portfolio. The Funds 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.

                              VALUATION OF SHARES
 
NET ASSET VALUE
 
   
    The net asset value per share of each Portfolio and corresponding Master
Fund is calculated as of the close of the NYSE by dividing the total market
value of the Portfolio's investments and other assets, less any liabilities, by
the total outstanding shares of the stock of the respective Portfolio or Master
Fund. The value of the shares of each Portfolio will fluctuate in relation to
its own investment experience. The value of the shares of the Feeder Portfolios
and International Small Company Portfolio will fluctuate in relation to the
investment experience of the Master Funds in which such Portfolios invest.
Securities held by the Portfolios and the Master Funds which are listed on a
securities exchange and for which market quotations are available are valued at
the last quoted sale price of the day or, if there is no such reported sale, the
9-10 Series, the 6-10 Series, Tax-Managed U.S. 6-10 Small Company Portfolio, the
U.S. Large Company Series, DFA Real Estate Securities Portfolio, the Value
Master Funds, International Value Series, Emerging Markets Series, Emerging
Markets Small Cap Series and Dimensional Emerging Markets Value Fund value such
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. Securities issued by open-end investment
companies, such as the Master Funds, are valued using their respective net asset
values for purchase orders placed at the close of the NYSE. Unlisted securities
for which market quotations are readily available are valued at the mean between
the most recent bid and asked prices. The value of other assets and securities
for which no quotations are readily available (including restricted securities)
are determined in good faith at fair value in accordance with procedures adopted
by the Board of Directors. The net asset values per share of the International
Equity Portfolios (in respect of those Portfolios that are Feeder Portfolios and
International Small Company Portfolio, the Master Funds), the International
Value Series, Two-Year Global Fixed Income Series and DFA Five-Year Global Fixed
Income Portfolio are expressed in U.S. dollars by translating the net assets of
each Portfolio, or Master Fund using the mean between the most recent bid and
asked prices for the dollar as quoted by generally recognized reliable sources.
    
 
    Provided that the transfer agent has received the investor's Account
Registration Form in good order and the custodian has received the investor's
payment, shares of the Portfolio selected will be priced at the public offering
price calculated next after receipt of the investor's funds by the custodian.
The transfer agent or the Funds may from time to time appoint a sub-transfer
agent for the receipt of purchase orders and funds from certain investors. With
respect to such investors, the shares of the Portfolio selected will be priced
at the public offering price calculated after receipt of the purchase order by
the sub-transfer agent. The only difference between a normal purchase and a
purchase through a sub-transfer agent is that if the investor buys shares
through a sub-transfer agent, the purchase price will be the public offering
price next calculated after the sub-transfer agent receives the order, rather
than on the day the custodian receives the investor's payment (provided that the
sub-transfer agent has received the investor's purchase order in good order).
The value of the shares of the Fixed Income Portfolios, the One-Year Fixed
Income Series and Two-Year Global Fixed Income Series will tend to fluctuate
with interest rates because, unlike money market funds, these Portfolios and the
Series do not seek to stabilize the value of their respective shares by use of
the "amortized cost" method of asset valuation. Net asset value includes
interest on fixed income securities which is accrued daily. Securities which are
traded OTC and on a stock exchange 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 OTC market. Securities held by the
Fixed Income Portfolios, the One-Year Fixed Income Series and Two-Year Global
Fixed Income Series may be valued on the basis of prices provided by a pricing
service when such prices are believed to reflect the current market value of
such securities. Other assets and securities for which quotations are not
readily available will be valued in good faith at fair value using methods
determined by the Board of Directors.
 
    Generally, trading in foreign securities markets is completed each day at
various times prior to the close of the NYSE. The values of foreign securities
held by those Portfolios and Master Funds that invest
 
                                       51
<PAGE>
in such securities are determined as of such times for the purpose of computing
the net asset values of the Portfolios and Master Funds. If events which
materially affect the value of the investments of a Portfolio or Master Fund
occur subsequent to the close of the securities market on which such securities
are primarily traded, the investments affected thereby will be valued at "fair
value" as described above.
 
    Certain of the securities holdings of the Emerging Markets Series, Emerging
Markets Small Cap Series and the Dimensional Emerging Markets Value Fund in
Approved Markets may be subject to tax, investment and currency repatriation
regulations of the Approved Markets that could have a material effect on the
valuation of the securities. For example, such Master Funds might be subject to
different levels of taxation on current income and realized gains depending upon
the holding period of the securities. In general, a longer holding period (e.g.,
5 years) may result in the imposition of lower tax rates than a shorter holding
period (e.g., 1 year). The Master Funds may also be subject to certain
contractual arrangements with investment authorities in an Approved Market which
require a Master Fund to maintain minimum holding periods or to limit the extent
of repatriation of income and realized gains. As a result, the valuation of
particular securities at any one time may depend materially upon the assumptions
that a Master Fund makes at that time concerning the anticipated holding period
for the securities. Absent special circumstances as determined by the Board of
Directors or Trustees of the Master Fund, it is presently intended that the
valuation of such securities will be based upon the assumption that they will be
held for at least the amount of time necessary to avoid higher tax rates or
penalties and currency repatriation restrictions. However, the use of such
valuation standards will not prevent the Master Funds from selling such
securities in a shorter period of time if the Advisor considers the earlier sale
to be a more prudent course of action. Revision in valuation of those securities
will be made at the time of the transaction to reflect the actual sales proceeds
inuring to the Master Fund.
 
    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 are determined each day as of such close.
 
PUBLIC OFFERING PRICE
 
   
    It is management's belief that payment of a reimbursement fee by each
investor, which is used to defray significant costs associated with investing
proceeds of the sale of their shares to such investors, will eliminate a
dilutive effect such costs would otherwise have on the net asset value of shares
held by previous investors. Therefore, the shares of certain Portfolios are sold
at an offering price which is equal to the current net asset value of such
shares plus a reimbursement fee. The amount of the reimbursement fee represents
management's estimate of the costs reasonably anticipated to be associated with
the purchase of securities by those Portfolios and Master Funds and is paid to
the Portfolios and Master Funds and used by them to defray such costs. Such
costs include brokerage commissions on listed securities, imputed commissions on
OTC securities and a .5% Stamp Duty imposed on the purchase of stocks on the
ISE. Reinvestments of dividends and capital gains distributions paid by the
Portfolios and in-kind investments are not subject to a reimbursement fee. (See
"PURCHASE OF SHARES--In-Kind Purchases" and "DIVIDENDS, CAPITAL GAINS
DISTRIBUTIONS AND TAXES.") The table in "FEES AND EXPENSES" in this prospectus
identifies the Portfolios whose shares are sold at an offering price which is
equal to the current net asset value of such shares plus a reimbursement fee.
The reimbursement fee is expressed as a percentage of the net asset value of the
shares of the respective Portfolios.
    
 
    For each Portfolio that charges a reimbursement fee, except the DFA
International Small Cap Value and the International Small Company Portfolios,
the Master Funds in which the Portfolio invests also charges a reimbursement fee
equal to that charged by the respective Portfolio.
 
    In the case of the International Small Company Portfolio, the reimbursement
fee is equal to a blended rate of the reimbursement fees of the International
Master Funds. The blended rate is determined on a quarterly basis and is based
upon the target allocation in effect at the end of each quarter. The blended
 
                                       52
<PAGE>
rate will be calculated by multiplying the rate of reimbursement fee of each
International Master Funds by a fraction equal to the portion of the assets of
the Portfolio which, at such time, is being allocated to each International
Master Funds and adding the results thereof. If there is a change to the
reimbursement fee of an International Master Funds during a quarter, the blended
rate will be recalculated to reflect such change in the International Master
Funds' reimbursement fee.
 
    The public offering price of shares of the Domestic Equity Portfolios,
United Kingdom Small Company Portfolio, Large Cap International Portfolio, DFA
International Value Portfolio and the Fixed Income Portfolios is the net asset
value thereof next determined after the receipt of the investor's funds by the
custodian, provided that an Account Registration Form in good order has been
received by the transfer agent; no sales charge or reimbursement fee is imposed.
 
                               EXCHANGE OF SHARES
 
Investors may exchange shares of one Portfolio for those 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. or, in the case of the DFA International
Value Portfolio, to Dimensional Investment Group Inc., as follows:
 
                              Attn: Client Operations
                         1299 Ocean Avenue, 11th Floor
                             Santa Monica, CA 90401
 
    The minimum amount for an exchange is $100,000. Exchanges are accepted into
or from any of the Portfolios offered in this prospectus. Such exchange is
subject to any applicable reimbursement fee charged by a Portfolio in connection
with the sale of its shares.
 
    Investors in any Portfolio eligible for the exchange privilege also may
exchange all or part of their Portfolio shares into certain other 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 other 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 Portfolios or otherwise adversely affect the Funds, any
proposed exchange will be subject to the approval of the Advisor. Such approval
will depend on: (i) the size of the proposed exchange; (ii) the prior number of
exchanges by that shareholder; (iii) the nature of the underlying securities and
the cash position of the Portfolios involved in the proposed exchange; (iv) the
transaction costs involved in processing the exchange; and (v) the total number
of redemptions by exchange already made out of a 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, plus any applicable
reimbursement fee on purchases by exchange. Exchanges with respect to
International Small Company Portfolio and any of the Feeder Portfolios which
invest in the International Master Funds are not subject to a reimbursement fee.
"Good order" means a completed a letter of instruction specifying the dollar
amount to be exchanged, signed by all registered owners of the shares; and if a
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
 
                                       53
<PAGE>
have not been issued and the shares of the Portfolio being acquired are
registered in the investor's state of residence.
 
    There is no fee imposed on an exchange. However, the Funds reserve the right
to impose an administrative fee in order to cover the costs incurred in
processing an exchange. Any such fee will be disclosed in the prospectus. An
exchange is treated as a redemption and a purchase. Therefore, an investor could
realize a taxable gain or a loss on the transaction. The Funds reserve the right
to revise or terminate the exchange privilege, waive the minimum amount
requirement, limit the amount of or reject any exchange, as deemed necessary, at
any time.
 
                              REDEMPTION OF SHARES
 
REDEMPTION PROCEDURE
 
    Investors who desire to redeem shares of a Portfolio must first contact the
Advisor at (310) 395-8005. Each Portfolio will redeem shares at the net asset
value of such shares next determined, either: (1) where stock certificates have
not been issued, after receipt of a written request for redemption in good
order, by the transfer agent or (2) if stock certificates have been issued,
after receipt of the stock certificates in good order at the office of the
transfer agent. "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 (ordinarily 1:00 p.m. PST),
including: the stock certificate(s), if issued; 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 a 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 (STAMP), Stock Exchanges Medallion Program
(SEMP) and New York Stock Exchange, Inc. Medallion Signature Program (MSP).
Signature guarantees which are not a part of these programs will not be
accepted.
 
    Shareholders redeeming shares for which certificates have not been issued,
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 Funds reserve the right to send redemption proceeds
by check in their 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 which 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 Funds reserve 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 which were purchased by
check will not be made until the Funds can verify that the payments for the
purchase have been, or will be, collected, which may take up to fifteen 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 each Portfolio, the Funds reserve the right to redeem a
shareholder's account if the value of the shares in a specific Portfolio is $500
or less, whether because of redemptions, a decline in the Portfolio's net asset
value per share or any other reason. Before a Fund involuntarily redeems shares
from
 
                                       54
<PAGE>
such an account and sends the proceeds to the stockholder, the Fund will give
written notice of the redemption to the stockholder at least sixty days in
advance of the redemption date. The stockholder will then have sixty days from
the date of the notice to make an additional investment in order to bring the
value of the shares in the account for a specific Portfolio to more than $500
and avoid such involuntary redemption. The redemption price to be paid to a
stockholder for shares redeemed by a 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 Feeder Portfolio, the Feeder Portfolio may
make a redemption payment, in whole or in part, by a distribution of portfolio
securities that the Feeder Portfolio receives from the Master Fund in lieu of
cash. A Portfolio that is not a Feeder Portfolio may also make a redemption
payment, in whole or in part, by a distribution of Portfolio securities in lieu
of cash, when in the best interests of the Portfolio. Such distributions will be
made in accordance with the federal securities laws and regulations governing
mutual funds. Investors may incur brokerage charges and other transaction costs
selling securities that were received in payment of redemptions. The
International Equity, DFA Two-Year Global Fixed Income and DFA Five-Year Global
Fixed Income Portfolios reserve the right to redeem their shares in the
currencies in which their investments (and, in respect of the Feeder Portfolios
and International Small Company Portfolio, the currencies in which the
corresponding Master Funds' investments) are denominated. Investors may incur
charges in converting such securities to dollars and the value of the securities
may be affected by currency exchange fluctuations. The Tax-Managed Portfolios
and Series are authorized to make redemption payments solely by a distribution
of portfolio securities (or a combination of securities and cash) when it is
determined by the Advisor to be consistent with the tax management strategies
described in this prospectus.
 
                             THE FEEDER PORTFOLIOS
 
    Other institutional investors, including other mutual funds, may invest in
each Master Fund, and the expenses of such other funds and, correspondingly,
their returns may differ from those of the Feeder Portfolios. Please contact The
DFA Investment Trust Company and the Dimensional Emerging Markets Value Fund
Inc. at 1299 Ocean Avenue, 11th Floor, Santa Monica, CA 90401, (310) 395-8005
for information about the availability of investing in a Master Fund and the
Dimensional Emerging Markets Value Fund other than through a Feeder Portfolio.
 
    The aggregate amount of expenses for a Feeder Portfolio and the
corresponding Master Fund may be greater than it would be if the Portfolio were
to invest directly in the securities held by the corresponding Master Fund.
However, the total expense ratios for the Feeder Portfolios and the Master Funds
are expected to be less over time than such ratios would be if the Portfolios
were to invest directly in the underlying securities. This arrangement enables
various institutional investors, including the Feeder Portfolios, to pool their
assets, which may be expected to result in economies by spreading certain fixed
costs over a larger asset base. Each shareholder in a Master Fund, including a
Feeder Portfolio, will pay its proportionate share of the expenses of that
Master Fund. By investing in shares of the International Master Funds,
International Small Company Portfolio will indirectly bear its pro rata share of
the operating expenses, management expenses and brokerage costs of such Master
Fund, as well as the expense of operating the Portfolio.
 
    The shares of the Master Funds will be offered to institutional investors
for the purpose of increasing the funds available for investment, to reduce
expenses as a percentage of total assets and to achieve other economies that
might be available at higher asset levels. Investment in a Master Fund by other
institutional investors offers potential benefits to the Master Funds, and
through their investment in the Master Funds, the Feeder Portfolios also.
However, such economies and expense reductions might not be achieved, and
additional investment opportunities, such as increased diversification, might
not be available if other
 
                                       55
<PAGE>
institutions do not invest in the Master Funds. Also, if an institutional
investor were to redeem its interest in a Master Fund, the remaining investors
in that Master Fund could experience higher pro rata operating expenses, thereby
producing lower returns, and the Master Fund's security holdings may become less
diverse, resulting in increased risk. Institutional investors that have a
greater pro rata ownership interest in a Master Fund than the corresponding
Feeder Portfolio could have effective voting control over the operation of the
Master Fund.
 
    If the Board of Directors of the relevant Fund determines that it is in the
best interest of a Feeder Portfolio, the Feeder Portfolio may withdraw its
investment in a Master Fund at any time. Upon any such withdrawal, the Board
would consider what action the Portfolio might take, including either seeking to
invest its assets in another registered investment company with the same
investment objective as the Portfolio, which might not be possible, or retaining
an investment advisor to manage the Portfolio's assets in accordance with its
own investment objective, possibly at increased cost. Shareholders of a Feeder
Portfolio will receive written notice thirty days prior to the effective date of
any change in the investment objective of its corresponding Master Fund. A
withdrawal by a Feeder Portfolio of its investment in the corresponding Master
Fund could result in a distribution in kind of portfolio securities (as opposed
to a cash distribution) to the Portfolio. Should such a distribution occur, the
Portfolio could incur brokerage fees or other transaction costs in converting
such securities to cash in order to pay redemptions. In addition, a distribution
in kind to the Portfolio could result in a less diversified portfolio of
investments and could affect adversely the liquidity of the Portfolio. Moreover,
a distribution in kind by the Master Fund corresponding to the U.S. 6-10 Small
Company, U.S. 9-10 Small Company, Enhanced U.S. Large Company, DFA One-Year
Fixed Income, DFA Two-Year Global Fixed Income, U.S. 4-10 Value, U.S. 6-10
Value, U.S. Large Cap Value, DFA International Value and Emerging Markets Value
Portfolios may constitute a taxable exchange for federal income tax purposes
resulting in gain or loss to such Portfolios. Any net capital gains so realized
will be distributed to such a Portfolio's shareholders as described in
"DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES."
 
                              FINANCIAL HIGHLIGHTS
 
    The Financial Highlights table is meant to help you understand each
Portfolio's financial performance for the past 5 years or, if shorter, the
period of that Portfolio's operations, as indicated by the table. (The U.S. 4-10
Value, and the Tax-Managed Portfolios had not begun operations by November 30,
1998 so no information is available for them.) The total returns in the table
represent the rate that you would have earned (or lost) on an investment in the
Portfolio, assuming reinvestment of all dividends and distributions. This
information has been audited by PricewaterhouseCoopers LLP (formerly Coopers &
Lybrand L.L.P.), whose report, along with the Portfolios' financial statements,
are included in the annual report which is available upon request.
 
   
    The "Transfer" transaction referred to below in footnotes to the Financial
Highlights refers to the transaction which took place on August 9, 1996, in
which four Portfolios, the Japanese Small Company Portfolio, the Pacific Rim
Small Company Portfolio, the United Kingdom Small Company Portfolio, and the
Continental Small Company Portfolio, respectively, each transferred their
investable assets in exchange for shares with equal values of a corresponding
Master Fund of the Trust.

                        PORTFOLIO CHARACTERISTICS AND POLICIES

     Each of the Portfolios identified as a "Feeder" (a "Feeder Portfolio") on
the cover page of this SAI seeks to achieve its investment objective by
investing all of its investable assets in a corresponding series of the DFA
Investment Trust Company (the "Trust") or in the case of the Emerging Markets
Value Portfolio, in the Dimensional Emerging Markets Value Fund Inc.  The series
of the Trust and Dimensional Emerging Markets Value Fund Inc. are referred to as
the "Master Funds."  Dimensional Fund Advisors Inc. (the "Advisor") serves as
investment advisor to each of the Portfolios, except the Feeder Portfolios and
each Master Fund, and provides administrative services to the Feeder Portfolios
and International Small Company Portfolio.  The International Small Company
Portfolio seeks to achieve its investment objective by investing in up to four
Master Funds (the "International Master Funds").  Capitalized terms not
otherwise defined in this SAI have the meaning assigned to them in the
prospectus.

     The following information supplements the information set forth in the
prospectus.  Unless otherwise indicated, the following information applies to
all of the Portfolios and Master Funds, including the Feeder Portfolios, through
their investment in the Master Funds.

     Each of the Portfolios and the Master Funds, other than the Five-Year
Global Fixed Income Portfolio, are diversified under the federal securities laws
and regulations.

     Because the structure of the Domestic Equity and International Equity
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, the 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 the
Portfolios 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 COMMISSIONS

     The following table depicts brokerage commissions paid by the Portfolios.
For the Feeder Portfolios, the amounts include commissions paid by the
corresponding Master Fund.

     The substantial increases or decreases in the amount of brokerage
commissions paid by certain Portfolios from year to year indicated in the
foregoing table resulted from increases or decreases in the amount of securities
that were bought and sold by those Portfolios. 

     Please note that while the following discussion relates to the policies of
the Portfolios with respect to brokerage commissions, it should be understood
that, with respect to a Feeder Portfolio and International Small Company
Portfolio, the discussion applies to the Master Fund in which the Feeder
Portfolio invests all of its assets and the International Master Funds,
respectively. 

     The Fixed Income Portfolios acquire and sell securities on a net basis with
dealers which 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, the
Advisor seeks to obtain the most favorable price for the securities being traded
among the dealers with whom the Fixed Income Portfolios effect transactions. 

     Portfolio transactions will be placed with a view to receiving the best
price and execution.  The Portfolios 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 which effect transactions
for the Portfolios to determine the effect that their trading has on the market
prices of the securities in which they invest.  The Advisor also checks the rate
of commission being paid by the Portfolios to their brokers to ascertain that
they are competitive with those charged by other brokers for similar services. 
Dimensional Fund Advisors Ltd. performs these services for the United Kingdom
and Continental Small Company Series and DFA Australia Limited performs these
services for the Japanese and Pacific Rim Small Company Series. Transactions
also may be placed with brokers who provide the Advisor or the sub-advisors with
investment research, such as reports concerning individual issuers, industries
and general economic and financial trends and other research services. 

   
     The OTC companies eligible for purchase by the U.S. 9-10 Small Company
Portfolio, the U.S. 6-10 Small Company Portfolio, the U.S. 6-10 Value Portfolio,
the U.S. 4-10 Value Portfolio and the DFA Real Estate Securities Portfolio, the
Tax Managed U.S. 5-10 Value Portfolio, the Tax Managed U.S. 6-10 Small Company
Portfolio and the Tax Managed U.S. Marketwide Value Series are thinly traded
securities.  Therefore, the Advisor believes it needs maximum flexibility to
effect OTC trades on a best execution basis.  To that end, the Advisor places
buy and sell orders with market makers, third market brokers, Instinet and with
brokers on an agency basis when the Advisor determines that the securities may
not be available from other sources at a more favorable price.  Third market
brokers enable the Advisor to trade with other institutional holders directly on
a net basis.  This allows the Advisor to sometimes trade larger blocks than
would be possible by going through a single market maker. 
    

     Instinet is an electronic information and communication network whose
subscribers include most market makers as well as many institutions.  Instinet
charges a commission for each trade executed on its system.  On any given trade,
the U.S. 9-10 Small Company Portfolio, the U.S. 6-10 Small Company Portfolio,
the Tax Managed U.S. 6-10 Small Company Portfolio, the Value Portfolios and the
DFA Real Estate Securities Portfolio, by trading through Instinet, would pay a
spread to a dealer on the other side of the trade plus a commission to Instinet.
However, placing a buy (or sell) order on Instinet 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 the
Portfolios can effect transactions at the best available prices. 

   
     During the fiscal year 1998, the Portfolios or, in the case of a Feeder
Portfolio, its corresponding Master Fund, paid commissions for securities
transactions to brokers which provided market price monitoring services, market
studies and research services to the Portfolios or Master Funds as follows:

     The investment advisory agreements permit the Advisor knowingly to pay
commissions on these transactions which 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 Funds. 
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 the Portfolios' shares. 

     Brokerage commissions for transactions in securities listed on the Tokyo
Stock Exchange ("TSE") and other Japanese securities exchanges are fixed.  Under
the current regulations of the TSE and the Japanese Ministry of Finance, member
and non-member firms of Japanese exchanges are required to charge full
commissions to all customers other than banks and certain financial
institutions, but members and licensed non-member firms may confirm transactions
to banks and financial institution affiliates located outside Japan with
institutional discounts on brokerage commissions.  The Japanese Small Company
Series has been able to avail itself of institutional discounts.  The Series'
ability to effect transactions at a discount from fixed commission rates depends
on a number of factors, including the size of the transaction, the relation
between the cost to the member or the licensed non-member firm of effecting such
transaction and the commission receivable, and the law, regulation and practice
discussed above.  There can be no assurance that the Series will continue to be
able to realize the benefit of discounts from fixed commissions.

     A Feeder Portfolio will not incur any brokerage or other costs in
connection with its purchase or redemption of shares of the corresponding Master
Fund.

                            INVESTMENT LIMITATIONS

     Each of the Portfolios has adopted certain limitations which may not be 
changed with respect to any 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 Portfolios will not:

     (1)  invest in commodities or real estate, including limited partnership
interests therein, except the DFA Real Estate Securities Portfolio, although
they may purchase and sell securities of companies which deal in real estate and
securities which are secured by interests in real estate, and all Portfolios
except the U.S. 9-10 and 6-10 Small Company Portfolios, the DFA One-Year Fixed

Portfolio, the DFA International Small Cap Value Portfolio and the Emerging 
Markets Value Portfolio; and (b) the Tax Managed U.S. 6-10 Small Company, Tax 
Managed DFA International Value and the U.S. 9-10 Small Company Portfolios 
are not subject to this limitation; or

     (17) issue senior securities (as such term is defined in Section 18(f) of
the Investment Company Act of 1940 (the "1940 Act")), except to the extent
permitted by the 1940 Act.

     The investment limitations described in (3), (4), (7), (9), (10), (11),
(12) and (16) above do not prohibit each Feeder Portfolio and International
Small Company Portfolio from investing all or substantially all of its assets in
the shares of another registered, open-end investment company, such as the
Master Funds or the International Master Funds, respectively.  The investment
limitations of each Master Fund are the same as those of the corresponding
Feeder Portfolio. 

     The investment limitations described in (1) and (15) above do not prohibit
each Portfolio that may purchase or sell financial futures contracts and options
thereon from making margin deposits to the extent permitted under applicable
regulations; and the investment limitations described in (1), (13) and (15)
above do not prohibit the Enhanced U.S. Large Company Portfolio from:  (i)
making margin deposits in connection with transactions in options; and (ii)
maintaining a short position, or purchasing, writing or selling puts, calls,
straddles, spreads or combinations thereof in connection with transactions in
options, futures, and options on futures and transactions arising under swap
agreements or other derivative instruments. 

     For purposes of (5) above, the Emerging Markets Portfolio, Emerging Markets
Small Cap Portfolio and Emerging Markets Value Portfolio (indirectly through
their investment in the corresponding Master Funds) may borrow in connection
with a foreign currency transaction or the settlement of a portfolio trade.  The
only type of borrowing contemplated thereby is the use of a letter of credit
issued on such Master Funds' behalf in lieu of depositing initial margin in
connection with currency futures contracts, and the Master Funds have no present
intent to engage in any other types of borrowing transactions under this
authority. 

     Although (2) above prohibits cash loans, the Portfolios are authorized to
lend portfolio securities.  Inasmuch as the Feeder Portfolios and International
Small Company Portfolio will only hold shares of certain Master Funds, these
Portfolios do not intend to lend those shares. 

     For the purposes of (7) above, DFA One-Year Fixed Income Portfolio, DFA
Two-Year Global Fixed Income Portfolio (indirectly through their investment in
the corresponding Master Funds) and DFA Five-Year Global Fixed Income Portfolio
may invest in commercial paper that is exempt from the registration requirements
of the Securities Act of 1933 (the "1933 Act") subject to the requirements
regarding credit ratings stated in the prospectus under "Description of
Investments."  Further, pursuant to Rule 144A under the 1933 Act, the Portfolios
may purchase certain unregistered (i.e. restricted) securities upon a
determination that a liquid institutional market exists for the securities.  If
it is decided that a liquid market does exist, the securities will not be
subject to the 10% or 15% limitation on holdings of illiquid securities stated
in (7) above.  While maintaining oversight, the Board of Directors has delegated
the day-to-day function of making liquidity determinations to the Advisor. For
Rule 144A securities to be considered liquid, there must be at least two dealers
making a market in such securities.  After purchase, the Board of Directors and
the Advisor will continue to monitor the liquidity of Rule 144A securities.

     For purposes of (12) above, the DFA Five-Year Global Fixed Income Portfolio
will not concentrate its investments in a single industry.  This means that it
will not invest more than 25% of its assets in securities of companies in any
one industry.  Management does not consider securities which are issued by the
U.S. government or its agencies or instrumentalities to be investments in an
"industry."  However, management currently considers securities issued by a
foreign government (but not the U.S. Government or its agencies or
instrumentalities) to be subject to the 25% limitation.  Thus, not more than 25%
of the Portfolio's total assets will be invested in securities issued by any one
foreign government or supranational organization.  The Portfolio might invest in
certain securities issued by companies, such as Caisse Nationale des
Telecommunication, a communications company, whose obligations are guaranteed by
a foreign government.  Management considers such a company to be within a
particular industry (in this case, the communications industry) and, therefore,
the Portfolio will invest in the

                                       8
<PAGE>

securities of such a company only if it can do so under the Portfolio's 
policy of not being concentrated in any single industry.

   
     Although not a fundamental policy subject to shareholder approval:  (1) the
Large Cap International and Small Company Portfolios, including the U.S. 6-10
Small Company, Tax Managed U.S. 6-10 Small Company, Japanese Small Company,
Pacific Rim Small Company, United Kingdom Small Company and Continental Small
Company Portfolios indirectly through their investment in the Master Funds, do
not intend to purchase interests in any real estate investment trust; and (2)
the Enhanced U.S. Large Company, U.S. 4-10 Value, Tax Managed 5-10 Value, Tax
Managed U.S. 6-10 Small Company, Tax Managed U.S. Marketwide Value, Tax Managed
DFA International Value, DFA Two-Year Global Fixed Income, International Small
Company, Emerging Markets Small Cap and Emerging Markets Value Portfolios
(directly or indirectly through their investment in the Master Funds) do not
intend to invest more than 15% of their net assets in illiquid securities. 

    

     The International Equity, DFA Two-Year Global Fixed Income and DFA 
Five-Year Global Fixed Income Portfolios (directly or indirectly through 
their investment in the Master Funds) may acquire and sell forward foreign 
currency exchange contracts in order to hedge against changes in the level of 
future currency rates.  Such contracts involve an obligation to purchase or 
sell a specific currency at a future date at a price set in the contract.  
While each Value Portfolio, the DFA International Value Portfolio, Tax 
Managed DFA International Value Portfolio and the DFA Real Estate Securities 
Portfolio (directly or indirectly through their investment in the Master 
Funds), have retained authority to buy and sell financial futures contracts 
and options thereon, they have no present intention to do so. 

     Notwithstanding any of the above investment restrictions, the Emerging
Markets Series, the Emerging Markets Small Cap Series and the Dimensional
Emerging Markets Value Fund may establish subsidiaries or other similar vehicles
for the purpose of conducting their investment operations in Approved Markets,
if such subsidiaries or vehicles are required by local laws or regulations
governing foreign investors such as the Master Funds or the Dimensional Emerging
Markets Value Fund or whose use is otherwise considered by the Master Funds or
the Dimensional Emerging Markets Value Fund to be advisable. Each Master Fund or
the Dimensional Emerging Markets Value Fund would "look through" any such
vehicle to determine compliance with its investment restrictions.

     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 Portfolios and Master Funds own, and does not
include assets which the Portfolios and Master Funds do not own but over which
they have effective control.  For example, when applying a percentage investment
limitation that is based on total assets, a Portfolio or Master Fund will
exclude from its total assets those assets which represent collateral received
by the Portfolio or Master Fund for its securities lending transactions.

     Unless otherwise indicated, all limitations applicable to the Portfolios'
and Master Funds' 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 or Master Funds' assets
invested in certain securities or other instruments resulting from market
fluctuations or other changes in a Portfolio's or Master Fund's total assets
will not require a Portfolio or Master Fund 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 it believes best reflects the security's quality and risk at that time,
which may be the higher of the several assigned ratings. 

                        OPTIONS ON STOCK INDICES

     The Enhanced U.S. Large Company Series may purchase and sell options on 
stock indices.  With respect to the sale of call options on stock indices, 
pursuant to published positions of the Securities and Exchange Commission 
(the "Commission"), the Enhanced U.S. Large Company Series will either (1) 
maintain with its custodian liquid assets equal to the contract value (less 
any margin deposits); (2) hold a portfolio of stocks substantially 
replicating the movement of the index underlying the call option; or (3) hold 
a separate call on the same index as the call written where the exercise 
price of the call held is (a) equal to or less than the exercise price of the 
call written, or (b) greater than the exercise price of the call written, 
provided the difference is maintained by the Series in liquid

                                       9
<PAGE>

assets in a segregated account with its custodian.  With respect to the sale 
of put options on stock indices, pursuant to published Commission positions, 
the Enhanced U.S. Large Company Series will either (1) maintain liquid assets 
equal to the exercise price (less any margin deposits) in a segregated 
account with its custodian; or (2) hold a put on the same index as the put 
written where the exercise price of the put held is (a) equal to or greater 
than the exercise price of the put written, or (b) less than the exercise 
price of the put written, provided an amount equal to the difference is 
maintained by the Series in liquid assets in a segregated account with its 
custodian.

     Prior to the earlier of exercise or expiration, an option may be closed out
by an offsetting purchase or sale of an option of the same series (type,
exchange, underlying index, exercise price, and expiration).  There can be no
assurance, however, that a closing purchase or sale transaction can be effected
when the Enhanced U.S. Large Company Series desires.

     The Enhanced U.S. Large Company Series will realize a gain from a closing
purchase transaction if the cost of the closing option is less than the premium
received from writing the option, or, if it is more, the Series will realize a
loss.  The principal factors affecting the market value of a put or a call
option include supply and demand, interest rates, the current market price of
the underlying index in relation to the exercise price of the option, the
volatility of the underlying index, and the time remaining until the expiration
date.

     If an option written by the Enhanced U.S. Large Company Series expires, the
Series realizes a gain equal to the premium received at the time the option was
written.  If an option purchased by the Enhanced U.S.Large Company Series
expires unexercised, the Series realizes a loss equal to the premium paid.

     The premium paid for a put or call option purchased by the Enhanced U.S.
Large Company Series is an asset of the Series.  The premium received for an
option written by the Series is recorded as a deferred credit.  The value of an
option purchased or written is marked to market daily and is valued at the
closing price on the exchange on which it is traded or, if not traded on an
exchange or no closing price is available, at the mean between the last bid and
asked prices. 

RISKS ASSOCIATED WITH OPTIONS ON INDICES

     There are several risks associated with transactions in options on indices.
For example, there are significant differences between the securities and
options markets that could result in an imperfect correlation between these
markets, causing a given transaction not to achieve its objectives.  The value
of an option position will reflect, among other things, the current market price
of the underlying index, the time remaining until expiration, the relationship
of the exercise price, the term structure of interest rates, estimated price
volatility of the underlying index and general market conditions.  A decision as
to whether, when and how to use options involves the exercise of skill and
judgment, and even a well conceived transaction may be unsuccessful to some
degree because of market behavior or unexpected events. 

     Options normally have expiration dates of up to 90 days.  The exercise
price of the options may be below, equal to or above the current market value of
the underlying index.  Purchased options that expire unexercised have no value. 
Unless an option purchased by the Enhanced U.S. Large Company Series is
exercised or unless a closing transaction is effected with respect to that
position, the Enhanced U.S. Large Company Series will realize a loss in the
amount of the premium paid and any transaction costs. 

     A position in an exchange-listed option may be closed out only on an
exchange that provides a secondary market for identical options.  Although the
Enhanced U.S. Large Company Series intends to purchase or write only those
options for which there appears to be an active secondary market, there is no
assurance that a liquid secondary market will exist for any particular option at
any specific time.  Closing transactions may be effected with respect to options
traded in the over the counter markets only by negotiating directly with the
other party to the option contract, or in a secondary market for the option if
such a market exists.  There can be no assurance that the Enhanced U.S. Large
Company Series will be able to liquidate an over the counter option at a
favorable price at any time prior to expiration.  In the event of insolvency of
the counter-party, the Series may be unable to liquidate an over the counter
option.  Accordingly, it may not be possible to effect closing transactions with
respect to certain options, with the result that the Enhanced U.S. Large Series
would have to exercise those options which they have

                                       10
<PAGE>

purchased in order to realize any profit.  With respect to options written by 
the Enhanced U.S. Large Company Series, the inability to enter into a closing 
transaction may result in material losses to the Series.

     Index prices may be distorted if trading of a substantial number of
securities included in the index is interrupted causing the trading of options
on that index to be halted.  If a trading halt occurred, the Enhanced U.S. Large
Company Series would not be able to close out options which it had purchased and
may incur losses if the underlying index moved adversely before trading resumed.
If a trading halt occurred and restrictions prohibiting the exercise of options
were imposed through the close of trading on the last day before expiration,
exercises on that day would be settled on the basis of a closing index value
that may not reflect current price information for securities representing a
substantial portion of the value of the index. 

     The Enhanced U.S. Large Company Series' activities in the options markets
may result in higher fund turnover rates and additional brokerage costs;
however, the Series may also save on commissions by using options as a hedge
rather than buying or selling individual securities in anticipation or as a
result of market movements. 

INVESTMENT LIMITATIONS ON OPTIONS TRANSACTIONS

     The ability of the Enhanced U.S. Large Company Series to engage in options
transactions is subject to certain limitations.  The Enhanced U.S. Large Company
Series will only invest in over-the-counter options to the extent consistent
with the 15% limit on investments in illiquid securities.

                              FUTURES CONTRACTS

Please note that while the following discussion relates to the policies of
certain Portfolios with respect to futures contracts, it should be understood
that with respect to a Feeder Portfolio, the discussion applies to the Master
Fund in which the Feeder Portfolio invests all of its assets and, with respect
to the International Small Company Portfolio, the International Master Funds.

     All Portfolios, except the U.S. 9-10, 6-10 Small Company and Tax Managed 
U.S. 6-10 Portfolios, the DFA One-Year Fixed Income Portfolio and the DFA 
Five-Year Government Portfolio, may enter into futures contracts and options 
on futures contracts.  Such Portfolios (with the exception of Enhanced U.S. 
Large Company Portfolio and its corresponding Master Fund) may enter into 
futures contracts and options on future contracts only for the purpose of 
remaining fully invested and to maintain liquidity to pay redemptions.  The 
Enhanced U.S. Large Company Portfolio may use futures contracts and options 
thereon to hedge against securities prices or as part of its overall 
investment strategy.

     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 which are standardized as to
maturity date and underlying financial instrument are traded on national futures
exchanges.  The Portfolios or Master Fund will be required to make a margin
deposit in cash or government securities with a broker or custodian to initiate
and maintain positions in futures contracts.  Minimal initial margin
requirements are established by the futures exchange and brokers may establish
margin requirements which 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 will be required.  Conversely, reduction in the contract
value may reduce the required margin resulting in a repayment of excess margin
to the Portfolio or Master Fund.  Variation margin payments are made to and from
the futures broker for as long as the contract remains open.  The Portfolios or
Master Funds expect to earn income on their margin deposits.  To the extent that
a Master Fund or Portfolio invests in futures contracts and options thereon for
other than bona fide hedging purposes, no Master Fund or Portfolio will enter
into such transactions if, immediately thereafter, the sum of the amount of
initial margin deposits and premiums required to establish such positions would
exceed 5% of the Master Fund's or Portfolio's net assets, after taking into
account unrealized profits and unrealized losses on such contracts it has
entered into; provided, however, 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 the 5%.  Pursuant to published positions of the Commission, 
the Portfolios or Master Funds may be required to maintain segregated 
accounts consisting of liquid assets, (or, as permitted under

                                       11

<PAGE>

applicable interpretations, enter into offsetting positions) in connection 
with its futures contract transactions in order to cover its obligations with 
respect to such contracts.

     Positions in futures contracts may be closed out only on an exchange which
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 or Master Fund would
continue to be required to make variation margin deposits.  In such
circumstances, if the Portfolio or Master Fund 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 which are traded on national futures exchanges and for
which there appears to be a liquid secondary market.

                          CASH MANAGEMENT PRACTICES

     All Portfolios and Master Funds engage 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, in the case of the Emerging Markets Master Funds, 
cash investments may be made for temporary defensive purposes during periods 
in which market, economic or political conditions warrant.

     All the Portfolios and Master Funds may invest cash in short-term 
repurchase agreements.  In addition, the following cash investments are 
permissible:

     *The percentage guidelines set forth above are not absolute limitations but
the Portfolios and Master Funds do not expect to exceed these guidelines under
normal circumstances.

     **Investments in money market mutual funds may involve duplication of
certain fees and expenses.

     ***To the extent that such Master Funds or Portfolios invest in futures 
contracts and options thereon for other than bona fide hedging purposes, no 
Master Fund or Portfolio will enter into such transactions if, immediately 
thereafter, the sum of the amount of initial margin deposits and premiums 
required to establish such positions would exceed 5% of the Master Fund's or 
Portfolio's net assets, after taking into account unrealized profits and 
unrealized losses on such contracts it has entered into; provided, however, 
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 the 5%.

                            CONVERTIBLE DEBENTURES

     Each of the International Equity Portfolios may invest up to 5% of its 
assets in convertible debentures issued by non U.S. companies located in the 
countries where the Portfolios are permitted to invest.  In addition, the 
6-10 Series and the 9-10 Series are authorized to invest in private 
placements of interest-bearing debentures that are convertible into common 
stock.  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 it 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, a 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 a 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 which are consistent with the 
Portfolio's investment objective and policies. 

                           PORTFOLIO TURNOVER RATES

     Generally, securities will be purchased with the expectation that they 
will be held for longer than one year. The portfolio turnover rate for the 
U.S. 4-10 Value Series is anticipated to be approximately 35%.  Because the 
relative market capitalizations of small companies compared with larger 
companies generally do not change 


                                      13

<PAGE>

substantially over short periods of time, the portfolio turnover rates of the 
Small Company Portfolios ordinarily are anticipated to be low.  The turnover 
rate for the International Small Company Portfolio is not expected to exceed 
25% per year.  Because the DFA Real Estate Securities Portfolio generally 
will hold securities for the long-term, its turnover rate ordinarily is 
anticipated to be low.  The portfolio turnover rate of the Emerging Markets 
Small Cap Series ordinarily is anticipated to be low and is not expected to 
exceed 20% per year.  The portfolio turnover rate of the Emerging Markets 
Fund is anticipated to be approximately 20%-90%, which reflects the purchase 
of value stocks and the sale of non-value stocks. 

                            DIRECTORS AND OFFICERS

     The Board of Directors of each Fund is responsible for establishing Fund 
policies and for overseeing the management of that Fund.  Each of the 
Directors and officers of DFAIDG is also a Director and officer of DIG, a 
Trustee and officer of the Trust and a Director and officer of the

PORTFOLIO

     The Funds have entered into administration agreements with the Advisor, 
on behalf of the Feeder Portfolios and International Small Company Portfolio. 
Pursuant to each administration agreement, the Advisor performs various 
services, including: supervision of the services provided by the Portfolio's 
custodian and transfer and dividend disbursing agent and others who provide 
services to the Fund for the benefit of the Portfolio; providing shareholders 
with information about the Portfolio and their investments as they or the 
Fund may request; assisting the Portfolio in conducting meetings of 
shareholders; furnishing information as the Board of Directors may require 
regarding the Master Funds, and any other administrative services for the 
benefit of the Portfolio as the Board of Directors may reasonably request.  
For its administrative services, the Feeder Portfolios and International 
Small Company Portfolio are obligated to pay the Advisor a monthly fee equal 
to one-twelfth of the percentages listed below:

U.S. Large Company..........................................    0.125%(a)

(a)  Pursuant to the terms of the administration agreement between U.S. Large 
     Company Portfolio and the Advisor, the Advisor has agreed to waive a 
     portion of its administration fee and/or assume the expenses of the 
     Portfolio to the extent (1) necessary to pay the ordinary operating 
     expenses of the Portfolio (except the administration fee); and (2) that 
     the direct expenses the portfolio bears as a shareholder of the Master 
     Fund, on an annual basis, exceeds 0.025% of the Portfolio's average net 
     assets.  Beginning August 9, 1996, in addition to the waiver/assumption 
     effective on December 1, 1995, the Advisor has agreed to assume expenses 
     or waive the fee payable by the U.S. Large Company Portfolio under the 
     administration agreement by an additional .09% of average assets on an 
     annual basis.  The above fees reflect that waiver.

(b)  Effective August 1, 1997, the Advisor has agreed to waive its
     administration fee to the extent necessary to reduce the direct and 
     indirect cumulative annual expenses of the Enhanced U.S. Large Company 
     Portfolio to not more than 0.45% of average net assets of the Portfolio on
     an annualized basis.

(c)  Effective August 9, 1996, the Advisor has agreed to waive its
     administration fee and assume the direct expenses of the Japanese Small 
     Company, United Kingdom Small Company, Continental Small Company and 
     Pacific Rim Small Company Portfolios to the extent necessary to keep the 
     direct annual expenses of each Portfolio to not more than 0.47% of average 
     net assets of the Portfolio on an annualized basis; this arrangement does 
     not extend to the fees and expenses of the Master Funds. 

(d)  The Advisor has agreed to waive its administration fee and assume the
     direct expenses of the International Small Company Portfolio to the extent
     necessary to keep the administration fee and direct annual expenses of the
     Portfolio to not more than 0.45% of average net assets of the Portfolio on
     an annualized basis.

   
     For the fiscal years ended November 30, 1998, 1997 and 1996, the Portfolios
(or their corresponding Master Funds) paid administrative fees to the Advisor as
set forth in the following table:

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, with equal, non-cumulative voting rights and no preferences as to 
conversion, exchange, dividends, redemption or any other feature.

     With respect to matters which require shareholder approval, shareholders 
are entitled to vote only with respect to matters which affect the interest 
of the class of shares (Portfolio) which they hold, except as otherwise 
required by applicable law.  If liquidation of a Fund should occur, the 
Fund's 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 class.  
Ordinarily, the Funds do not intend to hold annual meetings of shareholders, 
except as required by the federal securities laws and regulations governing 
mutual funds, or other applicable law. Each Fund's bylaws provide that 
special meetings of shareholders shall be called at the written request of at 
least 10% 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 federal securities laws and regulations 
governing mutual funds, including semi-annual and annual financial statements 
of the Funds, the latter being audited at least once each year.

     Whenever a Feeder Portfolio, as an investor in its corresponding Master 
Fund, is asked to vote on a shareholder proposal, the relevant Fund will 
solicit voting instructions from the Feeder Portfolio's shareholders with 
respect to the proposal.  The Directors of the Fund will then vote the Feeder 
Portfolio's shares in the Master Fund in accordance with the voting 
instructions received from the Feeder Portfolio's shareholders.  The 
Directors of the Fund will vote shares of the Feeder Portfolio for which they 
receive no voting instructions in accordance with their best judgment.  With 
regard to a Master Fund of the Trust organized as a partnership for federal 
tax purposes, if a majority shareholder of the Master Fund redeems its entire 
interest in the Master Fund, a majority in interest of the remaining 
shareholders in the Master Fund must vote to approve the continuing existence 
of the Master Fund or the Master Fund will be liquidated.

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

     The Funds 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 Funds 
will generally 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 Funds are closed.

     The TSE is closed on the following days in 1999: January 1, and 15, 
February 11, March 22, April 29, May 3, 4 and 5, July 20, September 15 and 
23, October 11, November 3 and 23 and December 23, 30 and 31.  Orders for the 
purchase and redemption of shares of the Japanese Small Company Portfolio 
received on those days will be priced as of the close of the NYSE on the next 
day that the TSE is open for trading.

     The Funds reserve the right, in their sole discretion, to suspend the 
offering of shares of any or all Portfolios or reject purchase orders when, 
in the judgement of management, such suspension or rejection is in the best 
interest of that Fund or a 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.

     Reimbursement fees may be charged prospectively from time to time based 
upon the future experience of the Portfolios that are 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."

     Each 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 Commission, (2) during any period 
when an emergency exists as defined by the rules of the Commission as a 
result of which it is not reasonably practicable for such 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 Commission may permit.

     Shareholders may transfer shares of any 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 of investing in the Portfolios.  Unless you are invested in the 
Portfolios through a retirement plan, you should consider the tax 
implications of investing and consult your own tax adviser.

DISTRIBUTIONS OF NET INVESTMENT INCOME

     Each Portfolio receives 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 its shareholders.  Any distributions by a Portfolio 
from such income will be taxable to a shareholder as ordinary income, whether 
they are received in cash or in additional shares.

DISTRIBUTIONS OF CAPITAL GAINS

     A Portfolio may derive capital gains and losses 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 shareholders as ordinary income.  Distributions paid from 
long-term capital gains realized by a Portfolio will be taxable to 
shareholders as long-term capital gain, regardless of how long the shares of 
the Portfolio have been held.  Any net short-term or long-term capital gains 
realized by a Portfolio (net of any capital loss carryovers) generally will 
be distributed once each year, and may be distributed more frequently, if 
necessary, in order to reduce or eliminate federal excise or income taxes on 
the Portfolio.

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, the Portfolios generally pay no federal income tax on the 
income and gains it distributes to its shareholders.  The Board reserves the 
right not to maintain the qualification of a Portfolio as a regulated 
investment company, if it determines that such course of action to be 
beneficial to shareholders.  In such case, a Portfolio will be subject to 
federal, and possibly state, corporate taxes on its taxable income and gains, 
and distributions to shareholders will be taxed as ordinary dividend income 
to the extent of a Portfolio's available earnings and profits.   Some of the 
Master Funds intend to qualify each year as regulated investment companies 
("RIC Series"), while others are taxable as partnerships for federal income 
tax purposes.

EXCISE TAX DISTRIBUTION REQUIREMENT

     The Code requires a Portfolio to distribute at least 98% of its taxable
ordinary income earned during the

                                     30

<PAGE>

calendar year and 98% of its capital gain net income earned during the twelve 
month period ending October 31 (in addition to undistributed amounts from the 
prior year) to you by December 31 of each year in order to avoid federal 
excise taxes.  Each Portfolio intends to declare and pay sufficient dividends 
in December (or in January that are treated by you as received in December) 
but does not guarantee and can give no assurances that its distributions will 
be sufficient to eliminate all such taxes.

EFFECT OF FOREIGN INVESTMENTS ON DISTRIBUTIONS

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

     A Portfolio which invests in foreign securities may be subject to 
foreign withholding taxes on income from certain of their foreign securities. 
 If more than 50% in value of the total assets of a Portfolio are invested in 
securities of foreign corporations, such Portfolio may elect to pass through 
to its shareholders their pro rata share of foreign income taxes paid by such 
Portfolio.  If this election is made, shareholders will be required to 
include in their gross income their pro rata share of foreign taxes paid by 
the Portfolio.  However, shareholders will be entitled to either 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.

DIVIDENDS RECEIVED DEDUCTION

     Portfolios which will receive virtually all their net investment income 
from the receipt of interest income or from investments in foreign securities 
are not expected to make distributions eligible for the dividends received 
deduction for corporations.   In the case of the other Portfolios, dividends 
from net investment income will generally qualify in part for the corporate 
dividends received deduction, but the portion of dividends so qualified 
depends on the aggregate qualifying dividend income received by the Portfolio 
from domestic (U.S.) sources.

REDEMPTION OF PORTFOLIO SHARES

     Redemptions and exchanges of Portfolio shares are taxable transactions 
for federal and state income tax purposes that cause a shareholder to 
recognize a gain or loss.  If a shareholder holds his shares as a capital 
asset, the gain or loss that he realizes will be capital gain or loss.  Any 
loss incurred on the redemption or exchange of shares held for six months or 
less will be treated as a long-term capital loss to the extent of any 
long-term capital gains distributed to the shareholder by the Portfolio on 
those shares.

     All or a portion of any loss that a shareholder realizes upon the 
redemption of a Portfolio's shares will be disallowed to the extent that the 
shareholder purchases other shares in the Portfolio (through reinvestment of 
dividends or otherwise) within 30 days before or after the share redemption. 
Any loss disallowed under these rules will be added to the shareholder's tax 
basis in the new shares purchased by the shareholder.

U.S. GOVERNMENT OBLIGATIONS

     Many states grant tax-free status to dividends paid from interest earned 
on direct obligations of the U.S. government, subject in some states to 
minimum investment requirements that must be met by a Portfolio.  Investments 
in GNMA/FNMA securities, bankers' acceptances, commercial paper and 
repurchase agreements collateralized by U.S. government securities do not 
generally qualify for tax-free treatment.  The rules on exclusion of this 
income are different for corporations.

COMPLEX SECURITIES

     A Portfolio or a Master Fund may invest in complex securities and such 
investments may be subject to

                                      31

<PAGE>

numerous special and complicated tax rules. These rules could affect whether 
gains or losses recognized by a Portfolio or Master Fund are treated as 
ordinary income or capital gain, accelerate the recognition of income to the 
Portfolio or Master Fund, defer a Portfolio or Master Fund's ability to 
recognize losses, and, in limited cases, subject the Portfolio or Master Fund 
to U.S. federal income tax on income from certain of its foreign investments. 
 In turn, these rules may affect the amount, timing or character of the 
income distributed to a shareholder by a Portfolio.

OTHER SPECIAL RULES APPLICABLE TO PORTFOLIOS WHICH INVEST IN MASTER FUNDS

     A Portfolio which invests in a Master Fund may be subject to certain 
special rules depending on whether the Master Fund in which such Portfolio 
invests is a RIC Series or is a Master Fund taxable as a partnership under 
the Code.  For example, Portfolios which invest in RIC Series will not be 
permitted to passthrough foreign withholding taxes paid by such RIC Series to 
such Portfolio's shareholders.  These special rules may affect the amount, 
timing or character of the income distributed to shareholders of such 
Portfolios.

INFORMATION ON THE TAX CHARACTER OF DISTRIBUTIONS

     The Portfolios will inform shareholders of the amount and character of 
distributions at the time they are paid, and will advise shareholders of the 
tax status for federal income tax purposes of such distributions shortly 
after the close of each calendar year.  Shareholders who have not held shares 
of a Portfolio a full year may have designated and distributed to them as 
ordinary income or capital gain a percentage of income that is not equal to 
the actual amount of such income earned during the period of their investment 
in the Portfolio.

CALCULATION OF PERFORMANCE DATA
     
The Portfolios and the Master Funds may disseminate reports of their 
investment performance from time to time.  Investment performance is 
calculated on a total return basis; that is by including all net investment 
income and any realized and unrealized net capital gains or losses during the 
period for which investment performance is reported.  If dividends or capital 
gains distributions have been paid during the relevant period the calculation 
of investment performance will include such dividends and capital gains 
distributions as though reinvested in shares of the Portfolio or Master Fund. 
Standard quotations of total return, which include deductions of any 
applicable reimbursement fees, are computed in accordance with Commission 
Guidelines and are presented whenever any non-standard quotations are 
disseminated to provide comparability to other investment companies.  
Non-standardized total return quotations may differ from the Commission 
Guideline computations by covering different time periods, excluding 
deduction of reimbursement fees charged to investors and paid to the 
Portfolios which would otherwise reduce returns quotations.  In all cases, 
disclosures are made when performance quotations differ from the Commission 
Guideline.  Performance data is based on historical earnings and is not 
intended to indicate future performances.  Rates of return expressed on an 
annual basis will usually not equal the sum of returns expressed for 
consecutive interim periods due to the compounding of the interim yields. The 
Funds' annual reports to shareholders for the fiscal year ended November 30, 
1997 contain additional performance information. Copies of the annual reports 
are available upon request and without charge.

     With respect to the International Equity Portfolios and DFA Five-Year 
Global Fixed Income Portfolio, rates of return expressed as a percentage of 
U.S. dollars will reflect applicable currency exchange rates at the beginning 
and ending dates of the investment periods presented.  The return expressed 
in terms of U.S. dollars is the return one would achieve by investing dollars 
in the Portfolio at the beginning of the period and liquidating the 
investment in dollars at the end of the period.  Hence, the return expressed 
as a percentage of U.S. dollars combines the investment performance of the 
Portfolio as well as the performance of the local currency or currencies of 
the Portfolio.  Inasmuch as DFA Five-Year Global Fixed Income Portfolio 
intends to continually hedge against the risk of variations in currency 
exchange rates, the Advisor believes that the variation of the Portfolio's 
investment performance in relation to fluctuations in currency exchange rates 
will be minimized.

   

     Quotations of the annualized percentage total returns for the one-, five-,
and ten-year periods ended November 30, 1998 (as applicable) are set forth in
the prospectus.  Such quotations utilize the standardized method of calculation
required by the Commission, which is net of the cost of any current
reimbursement fees charged to investors and paid to the Portfolios. 

    
                                      32

Reimbursement fees of 1%, 1.5% and 1.5% were in effect from the inception of 
the Japanese, United Kingdom and Continental Small Company Portfolios, 
respectively, until June 30, 1995.  A reimbursement fee of 1% was in effect 
from the inception of DFA International Small Cap Value Portfolio until June 
30, 1995.  Effective June 30, 1995, the amount of the reimbursement fee was 
reduced with respect to Continental Small Company, Pacific Rim Small Company, 
Japanese Small Company, Emerging Markets and DFA International Small Cap 
Value Portfolios, and eliminated with respect to the United Kingdom Small 
Company Portfolio.  The current reimbursement fee for each Portfolio, 
expressed as a percentage of the net asset value of the shares of the 
Portfolios, is as follows: Continental Small Company, Pacific Rim Small 
Company and Emerging Markets Small Cap Portfolios-  1.00%; Japanese Small 
Company and Emerging Markets Portfolios- .50%; DFA International Small Cap 
Value Portfolio- .675%; and International Small Company Portfolio- .675%.

    

     A reimbursement fee of 1% was charged to investors in the U.S. 9-10 Small
Company Portfolio from December 9, 1986 through June 17, 1988.  A reimbursement
fee of 0.75% was charged to investors in the Large Cap International Portfolio
from the date of its inception until March 5, 1992.  In addition, for those
Portfolios in effect for less than one, five, or ten years, the time periods
during which the Portfolios have been active have been substituted for the
periods stated (which in no case extends prior to the effective dates of the
Portfolios' registration statements).  However, for purposes of calculating the
performance of a Feeder Portfolio, the performance of the corresponding Master
Fund may be utilized for the period prior to when the Feeder Portfolio commenced
operations, and, if applicable, restated to reflect the Feeder Portfolio's fees
and expenses.

     As the following formula indicates, the average annual total return is
determined by finding the average annual compounded rates of return over the
stated time period that would equate a hypothetical initial purchase order of
$1,000 to its redeemable value (including capital appreciation/depreciation and
dividends and distributions paid and reinvested less any fees charged to a
shareholder account) at the end of the stated time period.  The calculation
assumes that all dividends and distributions are reinvested at the public
offering price on the reinvestment dates during the period.  The quotation
assumes the account was completely redeemed at the end of each period and the
deduction of all applicable charges and fees.  According to the Commission
formula:

     In addition to the standardized method of calculating performance used by
the Commission, the Portfolios and Master Funds may disseminate other
performance data and may advertise total return performance calculated on a
monthly basis.

P(1 + T)n = ERV 
where:
P =   a hypothetical initial payment of $1,000 
T =   average annual total return 
n =   number of years 
ERV = ending redeemable value of a hypothetical $1,000 payment made at
      the beginning of the one-, five-, and ten-year periods at the end of the
      one-, five-, and ten-year periods (or fractional portion thereof).

     The Portfolios may compare their 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 which 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 Portfolios 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 Portfolios or to the Advisor, should be considered in light of 
a 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.
