    THE FUND
 
   
    This prospectus relates to twenty-eight separate Portfolios of the Fund.
Each Portfolio, in effect, represents a separate mutual fund with its own
investment objective and policies. The investment objective of each Portfolio is
a fundamental policy and may not be changed without the affirmative vote of a
majority of its outstanding securities. Investors may choose to invest in one or
more of the Portfolios. Proceeds from the sale of shares of a Portfolio will be
invested in accordance with that Portfolio's investment objective and policies.
A shareholder will be entitled to a pro rata share of all dividends and
distributions arising from the assets of the Portfolio in which he invests. Upon
redeeming shares, a shareholder will receive the current net asset value per
share of the Portfolio represented by the redeemed shares.
    
 
   
    INVESTMENT OBJECTIVES--SMALL COMPANY PORTFOLIOS                           --
    
 
   
    The investment objective of each of the following Portfolios (the "Small
Company Portfolios") is to achieve long-term capital appreciation by investing
in marketable stocks of small companies. In addition, the Tax Managed U.S. 6-10
Small Company Portfolio seeks 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 in order to
minimize taxable distributions to investors:
    
 
   
U.S. 9-10 Small Company Portfolio       U.S. 6-10 Small Company Portfolio
Japanese Small Company Portfolio        Tax Managed U.S. 6-10 Small Company

Continental Small Company Portfolio     United Kingdom Small Company Portfolio
International Small Company Portfolio   Pacific Rim Small Company Portfolio
 
    
 
   
    The size of a company will be measured by its relative market
capitalization. Each Portfolio, except the International Small Company Portfolio
and Tax Managed U.S. 6-10 Small Company Portfolio invests all of its assets in a
corresponding Series of the Trust. The International Small Company Portfolio
invests all of its assets in four Series of the Trust: Japanese Small Company,
Pacific Rim Small Company, United Kingdom Small Company and Continental Small
Company Series (collectively, the "Underlying Series"). The Tax Managed U.S.
6-10 Small Company Portfolio directly invests in its own portfolio securities.
Each corresponding Series of the Trust and the Tax Managed U.S. 6-10 Small
Company Portfolio will be structured by generally basing the amount of each
security purchased on the issuer's relative market capitalization, applied on a
basis of descending values, with a view to achieving a reasonable reflection of
the relative market capitalizations of its portfolio companies. (See "INVESTMENT
OBJECTIVES AND POLICIES--THE SMALL COMPANY PORTFOLIOS.")

Generally, the Series will acquire high quality obligations which mature within

concentrate investments in the banking industry under certain circumstances.

the Emerging Markets Small Cap Portfolio; 0.50% of the net asset value of the
shares of Japanese Small Company Portfolio, Emerging Markets Portfolio and
Emerging Markets Value Portfolio; and 0.675% of the net asset value of the
shares of DFA International Small Cap Value Portfolio. The reimbursement fee for
the International Small Company Portfolio is based on the current target
investment allocations among the Underlying Series. 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 Underlying Series. 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.
 
    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. 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 Underlying Series. 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 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 Funds and Underlying Series 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 Series of the Trust 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.")

(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 and,
    therefore, stabilize the return of the Portfolio for all existing
    shareholders. (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 Emerging Markets
    Value Fund charge a reimbursement fee to purchasers of shares, including
    International Small Company Portfolio, equal to the reimbursement fee
    charged by its corresponding Feeder Portfolio as set forth above.

(1) Feeder Portfolio
 
(2) Prior to November 30, 1997, the U.S. 9-10 Small Company Portfolio invested
    its assets directly in stocks of small companies. The above figures have
    been restated to reflect estimated aggregate annualized operating expenses
    of the U.S. 9-10 Small Company Portfolio and its corresponding Series as
    though the Portfolio's assets had been invested in the Series during the
    fiscal year ended November 30, 1997.
 
(3) 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 Series, on an annual
    basis, exceed 0.025% of the Portfolio's average net assets.
 
                                       9
<PAGE>
    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. Absent
    this arrangement, the annualized ratio of total operating expenses to
    average net assets for U.S. Large Company Portfolio for the fiscal year
    ended November 30, 1997, would have been 0.35%.
 
(4) 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 its 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. The above
    figures have been restated to reflect operating expenses as though that
    waiver had been in effect throughout the fiscal year ended November 30,
    1997. Absent this arrangement, the annualized ratio of total operating
    expenses to average net assets for the Portfolio was 0.54%.
 
(5) "Other Expenses" are annualized estimates based on anticipated fees and
    expenses through the fiscal year ending November 30, 1998.
 
(6) Effective December 20, 1996, the investment advisory fee payable by the Fund
    on behalf of the DFA Real Estate Securities Portfolio to the Advisor was
    reduced from .325% of the Portfolio's average net assets on an annual basis
    to .30% of the Portfolio's average net assets on an annual basis. Effective
    December 11, 1996, the sub-advisory agreement between the Fund, on behalf of
    the Portfolio, and Aldrich, Eastman and Waltch L.P. ("AEW") terminated;
    pursuant to the terms of the sub-advisory agreement previously in effect,
    the Portfolio paid AEW a fee equal to .175% of its average net assets on an
    annual basis. The above figures have been restated to reflect the reduction
    in the advisory fee and termination of the sub-advisory agreement as though
    they were both in effect throughout the fiscal year ended November 30, 1997.
    See "Management of the Fund."
 
(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 Trust Series. For the fiscal year ended November 30, 1997,
    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 the indirect payment of a portion of the
    management fee of each Underlying Series, which is equal to 0.10% of the
    average net assets of such Series 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 Underlying Series. 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 Underlying Series. The Advisor was not required to waive
    fees or assume expenses for the fiscal year ended November 30, 1997.
 
   
(9) "Other Expenses" are annualized estimates based on anticipated fees and
    expenses through the fiscal year ending November 30, 1999.
    
 
    For purposes of waivers and/or expense assumptions, the annual expenses are
those expenses incurred in any period consisting of twelve consecutive months.
The Advisor retains the right in its sole discretion to modify or eliminate the
waiver of a portion of its fees or assumption of expenses in the future.

    The purpose of the above expense table and Example is to assist investors in
understanding the various costs and expenses that an investor in the Portfolios
will bear directly or indirectly. THE EXAMPLE SHOULD NOT BE CONSIDERED A
REPRESENTATION OF PAST OR FUTURE EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR
LESSER THAN THOSE SHOWN.
 
    With respect to the Feeder Portfolios and International Small Company
Portfolio, the table summarizes the aggregate annual operating expenses of both
the Portfolios and the Master Funds or Underlying Series in which the Portfolios
invest. (See "MANAGEMENT OF THE FUND" for a description of Portfolio, Master
Fund and Underlying Series expenses.) The Board of Directors of the Fund has
considered whether such expenses will be more or less than they would be if the
Feeder Portfolios were to invest directly in the securities held by the Master
Funds. 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 is because this
arrangement enables various institutional investors, including the Feeder
Portfolios, to pool their assets, which may be
 
                                       11
<PAGE>
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 Underlying Series, International Small Company
Portfolio will indirectly bear its pro rata share of the operating expenses,
management expenses and brokerage costs of such Series, as well as the expense
of operating the Portfolio.
 
   
    The Emerging Markets Small Cap, the Emerging Markets Value, Tax Managed U.S.
6-10 Small Company, Tax Managed U.S. Large Cap Value, Tax Managed U.S. 4-10
Value and Tax Managed DFA International Value Portfolios (and their
corresponding Master Funds) are new and, therefore, the above example is based
on estimated expenses for their respective current fiscal years and does not
extend over five and ten-year periods.
    
 
    For the fiscal year ended November 30, 1997, the equity Portfolios or Master

 ** Represents the combined ratios for The Emerging Markets Portfolio and The
    Emerging Markets Small Cap Portfolio and their respective pro-rata share of
    their Master Fund Series for the period ended November 30, 1996 and
    subsequent periods.
 
   
 (a) Had certain waivers and assumptions of expenses not been in effect, the
     ratios of expenses to average net assets for the periods ended November 30,
     1994 and 1993 would have been 0.73% and 0.82%, respectively, and the ratio
     of net investment income to average net assets for their periods ended
     November 30, 1994 and 1993 would have been 1.38% and 1.23%, respectively.
    
 
   
 (b) Because of commencement of operations and related preliminary transaction
     costs, these ratios are not necessarily indicative of future ratios.

                             THE FEEDER PORTFOLIOS
 
   
    Each of the eighteen Feeder Portfolios seeks to achieve its investment
objective by investing all of its investable assets in a corresponding Series of
the Trust, an open-end management investment company, registered under the
Investment Company Act of 1940 (the "1940 Act"), that issues Series having the
same investment objective as each of those Portfolios. The Emerging Markets
Value Portfolio seeks to achieve its investment objective by investing all of
its investable assets in the Emerging Markets Value Fund, an open-end management
investment company, registered under the 1940 Act, that has the same investment
objective as the Emerging Markets Value Portfolio. This investment activity is
unlike many other investment companies which directly acquire and manage their
own portfolio of securities. The investment objective of a Feeder Portfolio may
not be changed without the approval of its shareholders. The investment
objective of a Master Fund may not be changed without approval of the
shareholders of that Master Fund. 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.
    
 
   
    This prospectus describes the investment objective, policies and
restrictions of each Feeder Portfolio and its corresponding Master Fund. (See
"INVESTMENT OBJECTIVES AND POLICIES--SMALL COMPANY PORTFOLIOS--U.S. 6-10 Small
Company Portfolio, U.S. 9-10 Small Company Portfolio, Japanese Small Company
Portfolio, United Kingdom Small Company Portfolio, Continental Small Company
Portfolio and Pacific Rim Small Company Portfolio"; "ENHANCED U.S. LARGE COMPANY
PORTFOLIO--Investment Objective and Policies"; "U.S. LARGE COMPANY
PORTFOLIO--Investment Objective and Policies"; "VALUE PORTFOLIOS--Investment
Objectives and Policies"; "INVESTMENT OBJECTIVES AND POLICIES--FIXED INCOME
PORTFOLIOS-DFA One-Year Fixed Income Portfolio; DFA Two-Year Global Fixed Income
Portfolio"; "RWB/DFA INTERNATIONAL HIGH BOOK TO MARKET PORTFOLIO--Investment
Objective and Policies"; and "EMERGING MARKETS PORTFOLIO, EMERGING MARKETS SMALL
CAP PORTFOLIO AND EMERGING MARKETS VALUE PORTFOLIO--Investment Objectives and
Policies.") In addition, an investor should read "MANAGEMENT OF THE FUND" for a
description of the management and other expenses associated with the Feeder
Portfolios' investment in the Master Funds. 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 Trust and the Emerging Markets Value
Fund at 1299 Ocean Avenue, 11th Floor, Santa Monica, CA 90401, (310) 395-8005
for information about the availability of investing in a Series of the Trust and
the Emerging Markets Value Fund other than through a Feeder 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 Fund 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 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.
 
    Further, if a Master Fund changes its investment objective in a manner which
is inconsistent with the investment objective of a corresponding Feeder
Portfolio and the shareholders of the Portfolio fail to approve a similar change
in the investment objective of the Portfolio, the Portfolio would be forced to
withdraw its investment in the Master Fund and either seek to invest its assets
in another registered investment company with the same investment objective as
the Portfolio, which might not be possible, or retain an investment advisor to
manage the Portfolio's assets in accordance with its own investment
 
                                       31
<PAGE>
objective, possibly at increased cost. 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 Series
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, RWB/DFA International
High Book to Market 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" below.
 
    Finally, the Feeder Portfolios' investment in the shares of the Master Funds
is relatively new and results in certain operational and other complexities.
However, management believes that the benefits to be gained by shareholders
outweigh the additional complexities and that the risks attendant to such
investment are not inherently different from the risks of direct investment in
securities of the type in which the Master Funds invest.
 
                            SMALL COMPANY PORTFOLIOS
 
INVESTMENT OBJECTIVE AND POLICIES
 
    Each Small Company Portfolio, and the U.S. 6-10 Small Company, U.S. 9-10
Small Company, Japanese Small Company, Pacific Rim Small Company, United Kingdom
Small Company and Continental Small Company Series of the Trust (the "Small
Company Series"), operate as a diversified investment company whose investment
objective is to achieve long-term capital appreciation. The Small Company
Portfolios provide investors with access to securities portfolios consisting of
small U.S., Japanese, United Kingdom, European and Pacific Rim companies.
Company size will be determined for purposes of these Portfolios and Series
solely on the basis of a company's market capitalization. "Market
capitalization" for domestic securities will be calculated by multiplying the
price of a company's stock by the number of its shares of outstanding common
stock. "Market capitalization" for foreign securities will be calculated using
the number of outstanding stocks of the company that are similar to domestic
common stocks.
 
   
    Each Small Company Series and Tax Managed U.S. 6-10 Small Company Portfolio
intends to invest at least 80% of its assets in equity securities of U.S.,
Japanese, United Kingdom, European and Pacific Rim small companies, as defined
herein, and as applicable to the Series. The Small Company Series and Tax
Managed U.S. 6-10 Small Company Portfolio 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, not only in the U.S. but in other
developed countries as well, 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 Small Company Series 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 minimize 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.

                      INVESTMENT OBJECTIVES AND POLICIES--
                            SMALL COMPANY PORTFOLIOS
 
U.S. 6-10 SMALL COMPANY PORTFOLIO
 
    U.S. 6-10 Small Company Portfolio pursues its investment objective by
investing 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 smaller one-half (deciles 6 through 10) of
companies listed on the New York Stock Exchange ("NYSE"). The 6-10 Series will
purchase common stocks of companies whose shares are listed on the NYSE, the
American Stock Exchange (the "AMEX") and traded in the over-the-counter market
("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 "INVESTMENT OBJECTIVES
AND POLICIES--THE SMALL COMPANY PORTFOLIOS--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
Series' net assets at the time of purchase.
 
   
TAX MANAGED U.S. 6-10 SMALL COMPANY PORTFOLIO
    
 
   
    The Tax Managed U.S. 6-10 Small Company Portfolio pursues its investment
objective by investing its assets in the same 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.)
    
 
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 "INVESTMENT OBJECTIVES AND POLICIES--SMALL COMPANY
PORTFOLIOS--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 Series' net
assets at the time of purchase.
 
JAPANESE SMALL COMPANY PORTFOLIO
 
    Japanese Small Company Portfolio pursues its investment objective by
investing all of its assets in the Japanese Small Company Series of the Trust
(the "Japanese Series"), which has the same investment
 
                                       33
<PAGE>
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. The Japanese
Series also may invest up to 5% of its assets in convertible debentures issued
by Japanese small companies. (See "INVESTMENT OBJECTIVES AND POLICIES--SMALL
COMPANY PORTFOLIOS--Portfolio Structure.")
 
UNITED KINGDOM SMALL COMPANY PORTFOLIO
 
    United Kingdom Small Company Portfolio pursues its investment objective by
investing 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
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. The United
Kingdom Series also may invest up to 5% of its assets in convertible debentures
issued by United Kingdom small companies. (See "INVESTMENT OBJECTIVES AND
POLICIES--SMALL COMPANY PORTFOLIOS--Portfolio Structure.")
 
CONTINENTAL SMALL COMPANY PORTFOLIO
 
    Continental Small Company Portfolio pursues its investment objective by
investing 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. As of the date of this prospectus,
the Continental Series may invest in small companies located in Austria,
Belgium, Denmark, Finland, France, Germany, Ireland, Italy, the Netherlands,
Norway, Spain, Sweden, and Switzerland, whose shares are traded principally in
securities markets located in those countries. 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 (i.e., on a
European basis). The Advisor typically will use the appropriate country indices
of the Financial Times-Actuaries World Index ("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
 
                                       34
<PAGE>
are available for purchase by non-resident 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 Continental Series also may invest up to 5% of its
assets in convertible debentures issued by European small companies. The
Continental Series has acquired the stocks of small companies located in
Belgium, Denmark, France, Germany, Italy, the Netherlands, Spain, Sweden and
Switzerland. When the Advisor determines that the investments of the Continental
Series in the stocks of small companies in those countries are sufficiently
diverse, the stocks of small companies located in other European countries may
be acquired on a country-by-country basis. In addition, 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 "INVESTMENT
OBJECTIVES AND POLICIES--SMALL COMPANY PORTFOLIOS--Portfolio Structure.")
 
PACIFIC RIM SMALL COMPANY PORTFOLIO
 
   
    Pacific Rim Small Company Portfolio pursues its investment objective by
investing 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
Asian countries whose shares are traded principally on the securities markets
located in those countries. As of the date of this prospectus, the Pacific Rim
Series may invest in small companies located in Australia, Hong Kong, Korea, New
Zealand and Singapore. In the future, the Advisor may add small companies
located in other Asian countries as securities markets in these countries become
accessible. 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. See "RISK FACTORS--ALL
PORTFOLIOS--INVESTING IN EMERGING MARKETS."
    
 
    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 (i.e., on a Pacific Rim basis). The Advisor typically
will use the appropriate country indices of the 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. The Pacific Rim Series also may invest up to 5% of its
assets in convertible debentures issued by small companies located in the
Pacific Rim. (See "INVESTMENT OBJECTIVES AND POLICIES--SMALL COMPANY
PORTFOLIOS--Portfolio Structure.")

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 Underlying
Series in such relative portions as determined by the Advisor from time to time.
A small portion of the assets of International Small Company Portfolio may be
invested in short-term, high-quality, fixed-income obligations pending
investment in shares of the Underlying Series and/or pending payment of
redemptions of its own shares for cash. For a complete description of the
investment objectives and policies, portfolio structure and transactions for
each Underlying Series, see "INVESTMENT OBJECTIVES AND POLICIES--SMALL COMPANY
PORTFOLIOS." 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 Small Company Portfolio invests in
the shares of the Underlying Series within the following percentage ranges:

</TABLE>
    
 
   
    The allocation of the assets of International Small Company Portfolio to be
invested in the Underlying Series will be determined by the Advisor on at least
a semi-annual basis. In setting the target allocation, the Advisor will first
consider the market capitalizations of all eligible companies in each of the
Underlying Series. The Advisor will calculate the market capitalizations for
each Underlying Series in the manner described under "INVESTMENT OBJECTIVES AND
POLICIES--SMALL COMPANY PORTFOLIOS." In determining the target allocations, the
Advisor, using its best judgment, will seek to eliminate the effect of cross
holdings between companies on a Series by Series 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 Underlying Series, 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 Series as a
consequence of certain restrictions imposed by the Malaysian government on the
repatriation of assets by foreign investors, such as the Series. See "RISK
FACTORS--ALL PORTFOLIOS--INVESTING IN EMERGING MARKETS." Under normal
conditions, the target allocations for investment by the Portfolio in the
Underlying Series 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 Company Series.
    
 
PORTFOLIO STRUCTURE
 
   
    Each Small Company Series and Tax Managed U.S. 6-10 Small Company Portfolio
is structured by generally basing the amount of each security purchased on the
issuer's relative market capitalization with a view to creating in each Series
and Tax Managed U.S. 6-10 Small Company Portfolio a reasonable reflection of the
relative market capitalizations of its portfolio companies. The following
discussion applies
    
 
                                       36
<PAGE>
   
to investment policies of each Small Company Series and Tax Managed U.S. 6-10
Small Company Portfolio.
    
 
    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 the 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 a part of a merger, consolidation or acquisition of assets). In
addition, the Advisor may exclude the stock of a company that otherwise meets
applicable market capitalization criterion if the Advisor determines in its best
judgment that other conditions exist that make the purchase of such stock
inappropriate.
 
    Deviation from strict market capitalization weighting will also occur
because the Advisor intends to purchase round lots only. Furthermore, in order
to retain sufficient liquidity, the relative amount of any security held may be
reduced from time to time from the level which strict adherence to market
capitalization weighting would otherwise require. A portion, but generally not
in excess of 20%, of assets may be invested in interest-bearing obligations,
such as money-market instruments, for this purpose, thereby causing further
deviation from strict 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. In addition, each Small Company Series and Tax Managed
U.S. 6-10 Small Company Portfolio may, in exchange for the issuance of shares,
acquire securities eligible for purchase or otherwise represented in their
portfolios at the time of the exchange. (See "In Kind Purchases.") While such
purchases and acquisitions might cause a temporary deviation from market
capitalization weighting, they would ordinarily be made in anticipation of
further growth of assets.
    
 
    If securities must be sold in order to obtain funds to make redemption
payments, they 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 "INVESTMENT OBJECTIVES AND POLICIES--SMALL
COMPANY PORTFOLIOS--Portfolio Transactions.")
 
   
    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 a not less than semi-annual basis, the
Advisor will determine the market capitalization of the largest small company
eligible for investment. Common stocks whose market capitalizations are not
greater than such company will be purchased. Additional investments generally
will not be made in securities which have appreciated in value sufficiently to
be excluded from the Advisor's then current market capitalization limit for
eligible portfolio securities. This may result in further deviation from strict
market capitalization weighting and such deviation could be substantial if a
significant amount of holdings increase in value sufficiently to be excluded
from the limit for eligible securities, but not by a sufficient amount to
warrant their sale. (See "INVESTMENT OBJECTIVES AND POLICIES--SMALL COMPANY
PORTFOLIOS--Portfolio Transactions.") A further deviation from market
capitalization weighting may occur if a Series or the Tax Managed U.S. 6-10
Small Company Portfolio invests a portion of its assets in privately placed
convertible debentures. Additional information regarding the investment policies
applicable to the U.S. 6-10 Small Company Portfolio appears in "TAX MANAGEMENT
STRATEGIES" below.
    
 
                                       37
<PAGE>
    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.
 
PORTFOLIO TRANSACTIONS
 
   
    On a periodic basis, the Advisor will review the holdings of each Small
Company Series and Tax Managed U.S. 6-10 Small Company Portfolio 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 and Tax Managed U.S. 6-10
Small Company Portfolio) 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
Series 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.
    
 
    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 may be disposed of, however, at any time when, in the Advisor's
judgment, circumstances, such as (but not limited to) tender offers, mergers and
similar transactions, or bids made for block purchases at opportune prices,
warrant their sale. Generally, 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. 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 policy of maintaining portfolios of companies with small market
capitalizations.
 
   
    In the case of the Tax Managed U.S. 6-10 Small Company Portfolio, management
strategies used by the Advisor 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. 6-10 Small Company Portfolio
should not be expected to adhere to its market capitalization weightings with
the same precision as the Small Company Series. (See "TAX MANAGEMENT STRATEGIES"
below.)
    
 
                          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, both in terms of
the price of the Portfolio's shares and its total investment return. The
Portfolio pursues its investment objective by investing 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 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.
 
                                       38
<PAGE>
    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. A
portion, however, generally not more than 5% of net assets, may be invested in
the same types of short-term fixed income obligations as may be acquired by the
DFA One-Year Fixed Income Portfolio, in order to maintain liquidity or to invest
temporarily uncommitted cash balances. (See " INVESTMENT OBJECTIVES AND
POLICIES--FIXED INCOME PORTFOLIOS--Description of Investments.")
 
    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 the 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 total assets would then consist of initial margin deposits
and premiums required to establish such contracts or options. Such investments
entail certain risks. (See "RISK FACTORS--ALL PORTFOLIOS.")
 
    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.
U.S. Large Company Series may lend securities to qualified brokers, dealers,
banks and other financial institutions for the purpose of earning additional
income. 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 &
POOR'S--INFORMATION AND DISCLAIMERS."
 
                     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 pursues its investment objective by investing 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, to the extent permissible pursuant to the
1940 Act, shares of investment companies that invest in stock indices. 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 (See "RISK FACTORS--ALL PORTFOLIOS"). 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
 
                                       39
<PAGE>
time, within the discretion of the Advisor and according to restraints imposed
by the 1940 Act. The Enhanced U.S. Large Company Series will maintain a
segregated account consisting of liquid assets (or, as permitted by applicable
regulation, 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.
For more information about Index Derivatives, see "RISK FACTORS--ALL
PORTFOLIOS."
 
    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.

                       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. As of the date of this prospectus, the
Portfolio may invest in the stocks of large companies in Australia, Belgium,
Denmark, France, Germany, Italy, Hong Kong, Japan, the Netherlands, New Zealand,
Norway, Singapore, Spain, Sweden, Switzerland and the United Kingdom. As the
Portfolio's asset growth permits and it may invest in the stocks of large
companies in Austria, Finland and Ireland. As of September 10, 1998, the
Portfolio ceased trading securities in Malaysia, as a consequence of recent
restrictions imposed by the Malaysian government on the repatriation of assets
by foreign investors, such as the Portfolio. (See "RISK FACTORS--ALL
PORTFOLIOS--Investing in Emerging Markets.")
    
 
    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. Such investments entail certain risks. (See "RISK
FACTORS--ALL PORTFOLIOS.") The Portfolio also may invest up to 5% of its assets
in convertible debentures issued by large non-U.S. companies.
 
    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. The Advisor, however, may exclude the stock of
such a company if the Advisor determines in its best judgment that other
conditions exist that make the purchase of such stock for a Portfolio
inappropriate.
 
    Deviation from market capitalization weighting will occur because the
Portfolio intends to purchase round lots only. Furthermore, in order to retain
sufficient liquidity, the relative amount of any security held by the Portfolio
may be reduced from time to time from the level which adherence to market
capitalization weighting would otherwise require. A portion, but generally not
in excess of 20%, of the Portfolio's assets may be invested in interest-bearing
obligations, such as money market instruments, thereby causing further deviation
from market capitalization weighting. A further deviation from market
capitalization weighting may occur if the Portfolio invests a portion of its
assets in convertible debentures.
 
    The Portfolio may make block purchases of eligible securities at opportune
prices even though such purchases exceed the number of shares which, at the time
of purchase, adherence to the policy of market capitalization weighting would
otherwise require. In addition, the Portfolio may acquire securities eligible
for purchase at the time of the exchange or otherwise represented in the
portfolio in exchange for the issuance of its shares. (See "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 the assets of the Portfolio.
 
    Changes in the composition and relative ranking (in terms of market
capitalization) of the stocks which are eligible for purchase by the Portfolio
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 large companies that will be revised
not less than semi-annually. Only common stocks whose market capitalizations are
not less than such minimum will be purchased by the Portfolio.
 
                                       41
<PAGE>
Additional investments will not be made in securities which have depreciated in
value to such an extent that they are not then considered by the Advisor to be
large companies. This may result in further deviation from market capitalization
weighting and such deviation could be substantial if a significant amount of the
Portfolio's holdings decrease in value sufficiently to be excluded from the then
current market capitalization requirement for eligible securities, but not by a
sufficient amount to warrant their sale.
 
    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 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.
 
    Securities which have depreciated in value since their acquisition will not
be sold by the Portfolio solely because prospects for the issuer are not
considered attractive, or due to an expected or realized decline in securities
prices in general. Securities may be disposed of, however, at any time when, in
the Advisor's judgment, circumstances warrant their sale, such as tender offers,
mergers and similar transactions, or bids made for block purchases at opportune
prices. Generally, 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. 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 policy of
maintaining a portfolio of companies with large market capitalizations.
 
                      DFA REAL ESTATE SECURITIES PORTFOLIO
 
INVESTMENT OBJECTIVE AND POLICIES
 
    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 may invest a portion of its assets,
 
                                       42
<PAGE>
ordinarily not more than 20%, in high quality, highly liquid, fixed income
securities such as money market instruments, including short-term repurchase
agreements. 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
or options for other than bona fide hedging purposes, the Portfolio will not
purchase futures contracts or options, if, as a result, an amount in excess of
5% of the net assets of the Portfolio would be deposited as initial margin
deposits and premiums required to establish such contracts or options.
 
PORTFOLIO STRUCTURE
 
    The Portfolio will operate as a diversified investment company. 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. In addition, the Advisor may exclude the securities of a company that
otherwise meets the applicable criteria described above if the Advisor
determines in its best judgment that other conditions exist that make the
inclusion of such security inappropriate.
 
    Deviation from strict market capitalization weighting will also occur in the
Portfolio because it intends to purchase round lots only. Furthermore, in order
to retain sufficient liquidity, the relative amount of any security held by the
Portfolio may be reduced from time to time from the level which strict adherence
to market capitalization weighting would otherwise require. A portion, but
generally not in excess of 20%, of the Portfolio's assets may be invested in
interest-bearing obligations, as described above, thereby causing further
deviation from strict market capitalization weighting.
 
    The Portfolio may make block purchases of eligible securities 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. In addition, the Portfolio may acquire securities
eligible for purchase or otherwise represented in the portfolio at the time of
the exchange in exchange for the issuance of its shares. (See "In Kind
Purchases.") While such purchases and acquisitions might cause a temporary
deviation from market capitalization weighting, they would ordinarily be made in
anticipation of further growth of the assets of the Portfolio. 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. On not less than a semi-annual basis,
the Advisor will prepare a schedule of eligible portfolio companies. Only equity
securities appearing on the then current schedule will be purchased for the
Portfolio.
 
    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
 
                                       43
<PAGE>
estate industry in addition to those described above as eligible for investment
as of the date of this prospectus.
 
PORTFOLIO TRANSACTIONS
 
    The Portfolio does not intend to purchase or sell securities based on the
prospects for the economy, the securities markets or, generally, 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.
 
    Generally, securities will be purchased with the expectation that they will
be held for longer than one year. However, securities may be sold at any time
when, in the Advisor's judgment, circumstances warrant their sale. Generally,
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.
 
                                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. Large Cap Value Portfolio 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. Large Cap Value Series (the "Tax Managed Large Cap Series") of
the Trust, respectively. Each Value Series has the same investment objective and
policies as the corresponding Value Portfolio. The Tax Managed U.S. 4-10 Value
Portfolio invests directly in portfolio securities. Ordinarily, each of the
Series and Tax Managed U.S. 4-10 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").
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 Structure," will be considered
eligible for investment. Large Cap Value and Tax Managed Large Cap Series 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, and the 6-10 Value Series will purchase common
stocks of companies whose market capitalizations are smaller than such company.
The 4-10 Value Series and Tax Managed U.S. 4-10 Value Portfolio 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. With respect to the 9th and 10th deciles, the 4-10 Series
and Tax Managed U.S. 4-10 Value Portfolio will only purchase such common stocks
when it is advantageous to do so through block trades with the Advisor's other
accounts. In measuring value, the Advisor may consider additional factors such
as cash flow, economic conditions and developments in the issuer's industry.
    
 
PORTFOLIO STRUCTURE
 
   
    Each Series and Tax Managed U.S. 4-10 Value Portfolio will operate as a
diversified investment company. Further, each Series and Tax Managed U.S. 4-10
Value Portfolio will not invest more than 25% of its total assets in securities
of companies in a single industry. The Series and Tax Managed U.S. 4-10 Value
Portfolio may invest a portion of their assets, ordinarily not more than 20%, in
high quality, highly liquid fixed income securities such as money market
instruments and short-term repurchase agreements. The Series and Tax Managed
U.S. 4-10 Value Portfolio will purchase securities that are listed on the
principal U.S. national securities exchanges and traded OTC.
    
 
                                       44
<PAGE>
   
    Each of the Value Series and Tax Managed U.S. 4-10 Value Portfolio will be
structured on a market capitalization basis, by generally basing the amount of
each security purchased on the issuer's relative market capitalization, with a
view to creating a reasonable reflection of the relative market capitalizations
of its portfolio companies. However, the Advisor may exclude the securities of a
company that otherwise meets the applicable criteria described above if the
Advisor determines in its best judgment that other conditions exist that make
the inclusion of such security inappropriate.
    
 
   
    Deviation from strict market capitalization weighting will also occur
because the Series and Tax Managed U.S. 4-10 Value Portfolio intend to purchase
round lots only and, with respect to the 4-10 Value Series and Tax Managed U.S.
4-10 Value Portfolio, because they intend to purchase common stocks in the 9th
and 10th deciles only through block trades, as described above. In order to
retain sufficient liquidity, the relative amount of any security held by a
Series or Tax Managed U.S. 4-10 Value Portfolio may be reduced, from time to
time, from the level which strict adherence to market capitalization weighting
would otherwise require. A portion, but generally not in excess of 20%, of a
Series' or Portfolio's assets may be invested in interest-bearing obligations,
as described above, thereby causing further deviation from strict market
capitalization weighting. The Series and Tax Managed U.S. 4-10 Value Portfolio
may make block purchases of eligible securities 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. In addition, the Series and the Portfolios may acquire
securities eligible for purchase at the time of the exchange or otherwise
represented in their portfolios in exchange for the issuance of their shares.
(See "In Kind Purchases.") While such purchases and acquisitions might cause a
temporary deviation from market capitalization weighting, they would ordinarily
be made in anticipation of further growth of the assets of a Series or the Tax
Managed U.S. 4-10 Value Portfolio.
    
 
   
    On not less than a semi-annual basis, for each Series and the Tax Managed
U.S. 4-10 Value Portfolio, the Advisor will calculate the book to market ratio
necessary to determine those companies whose stocks may be eligible for
investment. For additional information regarding the investment policies of the
Tax Managed U.S. 4-10 Value Portfolio, including its portfolio structure and
transactions, see "TAX MANAGEMENT STRATEGIES" below.
    
 
PORTFOLIO TRANSACTIONS
 
   
    The Series and the Tax Managed U.S. 4-10 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.
    
 
   
    Generally, securities will be purchased with the expectation that they will
be held for longer than one year. Large Cap Value 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 the Series, the 4-10 and 6-10 Value Series and the Tax Managed
U.S. 4-10 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. However, securities may be sold at any time when, in the Advisor's
judgment, circumstances warrant their sale.
    
 
   
    In addition, Large Cap Value 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 the Series. The 4-10 and
6-10 Value Series and Tax Managed U.S. 4-10 Value Portfolio may also sell
portfolio securities in the same circumstances, however, it is anticipated that
they will generally retain securities of issuers with relatively smaller market
capitalizations for longer periods, despite any decrease in the issuer's book to
market ratio.
    
 
                                       45
<PAGE>
   
    In the case of the Tax Managed U.S. 4-10 Value Portfolio, management
strategies used by the Advisor 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. 4-10 Value Portfolio should not
be expected to adhere to its market capitalization weightings with the same
precision as the Series. (See "TAX MANAGEMENT STRATEGIES" below.)
    
 
              RWB/DFA INTERNATIONAL HIGH BOOK TO MARKET PORTFOLIO
 
INVESTMENT OBJECTIVE AND POLICIES
 
   
    The investment objective of RWB/DFA International High Book to Market
Portfolio is to achieve long-term capital appreciation. The Portfolio pursues
its objective by investing 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 operates as a diversified investment company and 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. As of the date of
this prospectus, the International Value Series may invest in the stocks of
large companies in Australia, Belgium, Denmark, France, Germany, Hong Kong,
Italy, Japan, the Netherlands, New Zealand, Norway, Singapore, Spain, Sweden,
Switzerland and the United Kingdom. As the Series' asset growth permits, it may
invest in the stocks of large companies in other developed markets, including
Austria, Finland and Ireland. As of September 10, 1998, the International Value
Series ceased trading securities in Malaysia, as a consequence of recent
restrictions imposed by the Malaysian government on the repatriation of assets
by foreign investors, such as the Series. (See "RISK FACTORS--ALL
PORTFOLIOS--Investing in Emerging Markets.")
    
 
    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 total assets would then consist of initial margin deposits on such
contracts. Such investments entail certain risks. (See "RISK FACTORS--ALL
PORTFOLIOS.") The International Value Series also may invest up to 5% of its
assets in convertible debentures issued by large non-U.S. companies.
 
    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. The Advisor may exclude the stock of a company
that otherwise meets the applicable criteria if the Advisor determines in its
best
 
                                       46
<PAGE>
judgment that other conditions exist that make the purchase of such stock for
the International Value Series inappropriate.
 
    Deviation from market capitalization weighting also will occur because the
International Value Series intends to purchase round lots only. Furthermore, in
order to retain sufficient liquidity, the relative amount of any security held
by the International Value Series may be reduced from time to time from the
level which adherence to market capitalization weighting would otherwise
require. A portion, but generally not in excess of 20%, of the International
Value Series' assets may be invested in interest-bearing obligations, such as
money-market instruments, thereby causing further deviation from market
capitalization weighting. Such investments would be made on a temporary basis
pending investment in equity securities pursuant to the International Value
Series investment objective. A further deviation from market capitalization
weighting may occur if the International Value Series invests a portion of its
assets in privately placed convertible debentures.
 
    The International Value Series may make block purchases of eligible
securities at opportune prices even though such purchases exceed the number of
shares which, at the time of purchase, adherence to the policy of market
capitalization weighting would otherwise require. In addition, the International
Value Series may acquire securities eligible for purchase at the time of the
exchange or otherwise represented in its portfolio in exchange for the issuance
of its shares. (See "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 the assets of the International
Value Series.
 
    Changes in the composition and relative ranking (in terms of market
capitalization and book to market ratio) of the stocks which are eligible for
purchase by the International Value Series 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
large companies with high book to market ratios whose stock are eligible for
investment; such list will be revised not less than semi-annually. Only common
stocks whose market capitalizations are not less than the minimum on such list
will be purchased by the International Value Series. Additional investments will
not be made in securities which have depreciated in value to such an extent that
they are not then considered by the Advisor to be large companies. This may
result in further deviation from market capitalization weighting, and such
deviation could be substantial if a significant amount of the International
Value Series' holdings decrease in value sufficiently to be excluded from the
then current market capitalization requirement for eligible securities, but not
by a sufficient amount to warrant their sale.
 
    It is management's belief that the stocks of large 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 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.
 
    Securities which have depreciated in value since their acquisition will not
be sold by the International Value Series solely because prospects for the
issuer are not considered attractive, or due to an expected or realized decline
in securities prices in general. Securities may be disposed of, however, at any
time when, in the Advisor's judgment, circumstances warrant their sale, such as
tender offers, mergers and similar transactions, or bids made for block
purchases at opportune prices. Generally, 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. 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
 
                                       47
<PAGE>
light of the policy of maintaining a portfolio of companies with large market
capitalizations and high book to market ratios.
 
   
                 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 "RWB/DFA INTERNATIONAL HIGH BOOK TO MARKET
PORTFOLIO--Investment Objective and Policies" above.) However, the Portfolio
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 weighting.
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 Series 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 RWB/DFA International High Book to Market
Portfolio. (For additional information regarding the investment policies
applicable to the Tax Managed DFA International Value Portfolio, see "TAX
MANAGEMENT STRATEGIES" below.)
    
 
                  DFA INTERNATIONAL SMALL CAP VALUE PORTFOLIO
 
INVESTMENT OBJECTIVE 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. As of the date of this prospectus, the Portfolio may
invest in the stocks of small companies in Australia, Belgium, Denmark, France,
Germany, Hong Kong, Italy, Japan, the Netherlands, New Zealand, Norway,
Singapore, Spain, Sweden, Switzerland and the United Kingdom. As the Portfolio's
asset growth permits, it may invest in the stocks of small companies in other
developed markets, including Austria, Finland and Ireland. As of September 10,
1998, the Portfolio ceased trading securities in Malaysia, as a consequence of
recent restrictions imposed by the Malaysian government on the repatriation of
assets by foreign investors, such as the Portfolio. (See "RISK FACTORS--ALL
PORTFOLIOS--Investing in Emerging Markets.")
    
 
    Under normal market conditions, at least 65% of the Portfolio's assets will
be invested in small companies, as defined herein, 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. 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 transactions, 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 also may invest up to 5% of its assets in convertible debentures
issued by small non-U.S. companies.
 
                                       48
<PAGE>
    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. 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. The Advisor may exclude the stock of a company that otherwise meets the
applicable criteria if the Advisor determines in its best judgment that other
conditions exist that make the purchase of such stock for the Portfolio
inappropriate.
 
    Deviation from market capitalization weighting also will occur because the
Portfolio intends to purchase round lots only. Furthermore, in order to retain
sufficient liquidity, the relative amount of any security held by the Portfolio
may be reduced from time to time from the level which adherence to market
capitalization weighting would otherwise require. A portion, but generally not
in excess of 20%, of the Portfolio's assets may be invested in interest-bearing
obligations, such as money-market instruments, thereby causing further deviation
from market capitalization weighting. Such investments would be made on a
temporary basis pending investment in equity securities pursuant to the
Portfolio's investment objective. A further deviation from market capitalization
weighting may occur if the Portfolio invests a portion of its assets in
convertible debentures.
 
    The Portfolio may make block purchases of eligible securities at opportune
prices even though such purchases exceed the number of shares which, at the time
of purchase, adherence to the policy of market capitalization weighting would
otherwise require. In addition, the Portfolio may acquire securities eligible
for purchase at the time of the exchange or otherwise represented in the
portfolio in exchange for the issuance of its shares. (See "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 the assets of the Portfolio.
 
    Changes in the composition and relative ranking (in terms of market
capitalization and book to market ratio) of the stocks which are eligible for
purchase by the Portfolio 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 a list of eligible
small companies with high book to market ratios whose stock are eligible for
investment; such list will be revised not less than semi-annually. Only common
stocks whose market capitalizations are not greater than the maximum on such
list will be purchased by the Portfolio. Additional investments will not be made
in securities which have appreciated in value to such an extent that they are
not then considered by the Advisor to be small companies. This may result in
further deviation from market capitalization weighting, and such deviation could
be substantial if a significant amount of the Portfolio's holdings increase in
value sufficiently to be excluded from the then current market capitalization
requirement for eligible securities, but not by a sufficient amount to warrant
their sale.
 
    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
 
                                       49
<PAGE>
securities will be included in the Portfolio do pay dividends. It is
anticipated, therefore, that the Portfolio will receive dividend income.
 
    The Portfolio does not intend to purchase or sell securities based on the
prospects for the economy, the securities market or the individual issuers whose
shares are eligible for purchase. Securities may be disposed of, however, at any
time when, in the Advisor's judgment, circumstances warrant their sale, such as
tender offers, mergers and similar transactions, or bids made for block
purchases at opportune prices. Generally, 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. 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 policy of maintaining a portfolio of companies with small market
capitalizations and high book to market ratios.

                      AND EMERGING MARKETS VALUE 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 pursues its objective by investing
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 pursues its objective by
investing 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
Emerging Markets Value Fund is to seek long-term capital growth through
investment primarily in emerging market equity securities. The Emerging Markets
Value Portfolio pursues its objective by investing all of its assets in the
Emerging Markets Value Fund, which has the same investment objective and
policies as the Portfolio. Each Master Fund operates as a diversified investment
company and seeks to achieve its investment objective by investing in emerging
markets designated by the Investment Committee of the Advisor ("Approved
Markets"). Each 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").
    
 
MASTER FUND 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.
 
                                       50
<PAGE>
   
    The 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. No assurance can
be given that the Emerging Markets Value Fund's investment objective will be
achieved.
    
 
   
    The 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.
    
 
    Each 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 (e.g., restrictions on purchases by
foreigners), and each 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 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 Emerging
Markets Value Fund, the Fund will consider among other things, the data,
analysis and classification of countries published or disseminated by the
International Bank for Reconstruction (commonly known as the World Bank) and the
International Finance Corporation. 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,
investor information, government regulation, including fiscal and foreign
exchange repatriation rules and the availability of other access to these
markets by the investors of the Emerging Markets Series, the Emerging Markets
Small Cap Series and the Emerging Markets Value Fund.
    
 
   
    As of the date of this prospectus, the following countries are designated as
Approved Markets: Argentina, Brazil, Chile, Indonesia, Israel, Mexico,
Philippines, Portugal, South Korea, Thailand and
    
 
                                       51
<PAGE>
   
Turkey. Countries that may be approved in the future include but are not limited
to Colombia, Czech Republic, Greece, Hungary, India, Jordan, Nigeria, Pakistan,
Poland, Republic of China (Taiwan), Republic of South Africa, Venezuela and
Zimbabwe. As of September 10, 1998, the Emerging Markets Series, the Emerging
Markets Small Cap Series and the Emerging Markets Value Fund ceased trading
securities in Malaysia, as a consequence of recent restrictions imposed by the
Malaysian government on the repatriation of assets by foreign investors, such as
the Series and the Fund. (See "RISK FACTORS--ALL PORTFOLIOS--Investing in
Emerging Markets.")
    
 
    Each 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.
 
    Pending the investment of new capital in Approved Market equity securities,
each Master Fund will typically invest in money market instruments or other
highly liquid debt instruments denominated in U.S. dollars (including, without
limitation, repurchase agreements). In addition, each Master Fund may, for
liquidity, or for temporary defensive purposes during periods in which market or
economic or political conditions warrant, purchase highly liquid debt
instruments or hold freely convertible currencies, although no Master Fund
expects the aggregate of all such amounts to exceed 10% of its net assets under
normal circumstances.
 
    The Master Funds also may invest 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. The Master
Funds may also invest in money market mutual funds for temporary cash management
purposes. The 1940 Act limits investment by a Master Fund in shares of other
investment companies to no more than 10% of the value of a Master Fund's total
assets. If a Master Fund invests in another investment company, the Master
Fund's shareholders will bear not only their proportionate share of expenses of
the Master Fund (including operating expenses and the fees of the Advisor), but
also will bear indirectly similar expenses of the underlying investment company.
In some Approved Markets, it will be necessary or advisable for a Master Fund to
establish a wholly-owned subsidiary or a trust for the purpose of investing in
the local markets. Each Master Fund also may invest up to 5% of its assets in
convertible debentures issued by companies organized in Approved Markets.
 
PORTFOLIO STRUCTURE
 
    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 Emerging Markets Value Fund's criterion for
investment, it may not be included in a 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 capital as between Approved Markets.
    
 
                                       52
<PAGE>
   
    Changes in the composition and relative ranking (in terms of book to market
ratio) of the stocks which are eligible for purchase by the 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 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 a
Master Fund do pay dividends. It is anticipated, therefore, that the Master
Funds will receive dividend income.
 
    Generally, securities will be purchased with the expectation that they will
be held for longer than one year. However, securities may be disposed of at any
time when, in the Advisor's judgment, circumstances warrant their sale.
Generally, 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.
 
    For the purpose of converting U.S. dollars to another currency, or vice
versa, or converting one foreign currency to another foreign currency, each
Master Fund may enter into forward foreign exchange contracts. In addition, to
hedge against changes in the relative value of foreign currencies, each Master
Fund may purchase foreign currency futures contracts. A Master Fund will only
enter into such a futures contract if it is expected that the Master Fund will
be able readily to close out such contract. There can, however, be no assurance
that it will be able in any particular case to do so, in which case the Master
Fund may suffer a loss.
 
                                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 Master Fund 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 Fund or the Trust could experience delay in recovering the
loaned securities. Management believes that this risk can be controlled through
careful monitoring procedures.
 
          INVESTMENT OBJECTIVES AND POLICIES--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 value (i.e. a return in excess of the rate of inflation)
of invested capital with a minimum of risk. This objective will be pursued by
investing the assets of the Portfolio in 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,
 
                                       53
<PAGE>
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 will invest more than 25% of
its total assets in obligations of U.S. and/or foreign banks and bank holding
companies when the yield to maturity on these instruments exceeds the yield to
maturity on all other eligible portfolio investments of similar quality for a
period of five consecutive days when the NYSE is open for trading. (See
"Investments in the Banking Industry.")
 
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. This objective
will be pursued by investing the assets of the Portfolio in 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 will invest more than 25% of its total assets in
obligations of U.S. and/ or foreign banks and bank holding companies when the
yield to maturity on these instruments exceeds the yield to maturity on all
other eligible portfolio investments of similar quality for a period of five
consecutive days when the NYSE is open for trading. (See "Investment in the
Banking Industry.")
 
   
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
    
 
                                       54
<PAGE>
operating income in, at least three different countries, one of which may be the
United States. The Portfolio will acquire 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.
 
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 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 hold 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 total assets would then consist of initial and variation
margin deposits on such contracts or options. Such investments entail certain
risks. (See "RISK FACTORS--ALL PORTFOLIOS.")
 
DESCRIPTION OF INVESTMENTS

</TABLE>
    
 
    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.
 
                                       55
<PAGE>
    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--Non-convertible corporate debt securities
(E.G., bonds and debentures) which are issued by companies whose commercial
paper is rated Prime-1 by Moody's Investors Services, Inc. ("Moody's") or A-1 by
S&P and dollar-denominated obligations of foreign issuers issued in the U.S. If
the issuer's commercial paper is unrated, then the debt security would have to
be rated at least AA by S&P or Aa2 by Moody's. If there is neither a commercial
paper rating nor a rating of the debt security, then the Advisor must determine
that the debt security is of comparable quality to equivalent issues of the same
issuer rated at least AA or Aa2.
 
    4.  BANK OBLIGATIONS--Obligations of U.S. banks and savings-and-loan
associations and dollar-denominated obligations of U.S. subsidiaries and
branches of foreign banks, such as certificates of deposit (including marketable
variable rate certificates of deposit) and bankers' acceptances. Bank
certificates of deposit will only be acquired from banks having assets in excess
of $1,000,000,000.
 
    5.  COMMERCIAL PAPER--Rated, at the time of purchase, A-1 or better by S&P
or Prime-1 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.
 
    Investors should be aware that the net asset values of the Fixed Income
Portfolios may change as general levels of interest rates fluctuate. When
interest rates increase, the value of a portfolio of fixed-income securities can
be expected to decline. Conversely, when interest rates decline, the value of a
portfolio of fixed-income securities can be expected to increase.
 
    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.
 
                                       56
<PAGE>
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/or 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. For the purpose of this policy, which is a fundamental policy
of each Series and can only be changed by a vote of the shareholders of each
Series, banks and bank holding companies are considered to constitute a single
industry, the banking industry. The DFA One-Year Fixed Income Portfolio and DFA
Two-Year Global Fixed Income Portfolio each have the same fundamental policy,
which can only be changed by a vote of each Portfolio's shareholders, except
that the policy of each Portfolio does not apply to the extent that all or
substantially all of its assets are invested in its respective Series. When
investment in such obligations exceeds 25% of the total net assets of any of
these Series, such Series will be considered to be concentrating its investments
in the banking industry. As of the date of this prospectus, the One-Year Fixed
Income Series is concentrating its investment in this industry.
 
    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. As used herein, 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
monthly 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
    
 
                                       57
<PAGE>
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.
 
   
    The DFA Five-Year Global Fixed Income Portfolio is "non-diversified," as
defined in the 1940 Act, which means that, as to 75% of its total assets, more
than 5% may be invested in the securities of a single issuer. However, for
purposes of the Code, the Portfolio is "diversified" because as to 50% of its
total assets, no more than 5% may be invested in the securities of a single
issuer. The Portfolio 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 to be subject to the 25% limitation, with the
effect that not more than 25% of the Portfolio's total assets will be invested
in securities issued by any one foreign government. The Portfolio will not
invest more than 25% of its total assets in obligations of supranational
organizations. Finally, 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
securities of such a company only if it can do so under the Portfolio's policy
of not being concentrated in any single industry.
    
 
   
                           TAX MANAGEMENT STRATEGIES
    
 
   
    The Tax Managed U.S. 6-10 Small Company Portfolio, Tax Managed Large Cap
Value Series, Tax Managed U.S. 4-10 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.
    
 
   
    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 also will seek, when possible, not to dispose of a security until the
long-term holding period for capital gains for tax purposes has been satisfied.
Additionally, 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
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 to corporate shareholders, if because of timing
activities, the requisite holding period is not met. Except for the Tax Managed
Large Cap Value Series, portfolio holdings may be managed to minimize high
dividend-yielding securities and 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 Series. For example, the Advisor may exclude
    
 
                                       58
<PAGE>
   
the stock of a company that meets applicable market capitalization criterion in
order to avoid dividend income, and the Advisor may sell the stock of a company
that meets applicable market capitalization criterion in order to realize a
capital loss. Additionally, while the Value 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 taxable dividend
distributions 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 capital
gains realized, if any, upon redemption of shares of a Tax Managed Portfolio or
Series, if the amount realized on redemption is greater than the amount the
shareholders paid for the shares.
    
 
                          RISK FACTORS--ALL PORTFOLIOS
 
SMALL COMPANY SECURITIES
 
    Typically, securities of small companies are less liquid than securities of
large companies. Recognizing this factor, management will endeavor to effect
securities transactions in a manner to avoid causing significant price
fluctuations in the market for these securities. In addition, the prices of
small company securities may fluctuate more sharply than those of other

FOREIGN SECURITIES
 
   
    The International Equity Portfolios, International Value Series, DFA
Five-Year Global Fixed Income Portfolio, One-Year Fixed Income Series, Two-Year
Global Fixed Income Series and Enhanced U.S. Large Company Series (directly or
indirectly through their investment in the Master Funds) invest in foreign
issuers. Such investments involve risks that are not associated with investments
in U.S. public companies. Such risks may include legal, political and or
diplomatic actions of foreign governments, such as imposition of withholding
taxes on interest and dividend income payable on the securities held, possible
seizure or nationalization of foreign deposits, establishment of exchange
controls or the adoption of other foreign governmental restrictions which might
adversely affect the value of the assets held by the Portfolios and the Master
Funds. (Also see "Foreign Currencies and Related Transactions" below.) Further,
foreign issuers are not generally subject to uniform accounting, auditing and
financial reporting standards comparable to those of U.S. public companies, and
there may be less publicly available information about such companies than
comparable U.S. companies. The One-Year Fixed Income Series, Two-Year Global
Fixed Income Series, Enhanced U.S. Large Company Series and the Intermediate
Government Fixed Income and Five-Year Global Fixed Income Portfolios may invest
in obligations of supranational organizations. The value of the obligations of
these organizations may be adversely affected if one or more of their supporting
governments discontinue their support. Also, there can be no assurance that any
of the Portfolios will achieve its investment objective.
    
 
    The economies of many countries in which the Portfolios identified above and
the Master Funds invest are not as diverse or resilient as the U.S. economy, and
have significantly less financial resources. Some countries are more heavily
dependent on international trade and may be affected to a greater extent by
protectionist measures of their governments, or dependent upon a relatively
limited number of commodities and, thus, resistive to changes in world prices
for these commodities.
 
    In many foreign countries, stock markets are more variable than U.S. markets
for two reasons. Contemporaneous declines in both (i) foreign securities prices
in local currencies and (ii) the value of local currencies in relation to the
U.S. dollar can have a significant negative impact on the net asset value of a
Portfolio or Master Fund that holds the foreign securities. The net asset value
of the Portfolios and Master Funds are denominated in U.S. dollars, and,
therefore, declines in market price of both the foreign
 
                                       59
<PAGE>
securities held by a Portfolio or a Master Fund and the foreign currency in
which these securities are denominated will be reflected in the net asset value
of the Portfolio's and Master Fund's shares.
 
INVESTING IN EMERGING MARKETS
 
   
    The investments of the Emerging Markets Series, Emerging Markets Small Cap
Series and Emerging Markets Value Fund involve risks in addition to the usual
risks of investing in developed foreign markets. A number of emerging securities
markets restrict, to varying degrees, foreign investment in stocks. Repatriation
of investment income, capital and the proceeds of sales by foreign investors may
require governmental registration and/or approval in some emerging countries. In
some jurisdictions, such restrictions and the imposition of taxes are intended
to discourage shorter rather than longer-term holdings. While the Emerging
Markets Series, Emerging Markets Small Cap Series and Emerging Markets Value
Fund will invest only in markets where these restrictions are considered
acceptable to the Advisor, new or additional repatriation restrictions might be
imposed subsequent to a Master Fund's investment. If such restrictions were
imposed subsequent to investment in the securities of a particular country, a
Master Fund might, among other things, discontinue the purchasing of securities
in that country. Such restrictions will be considered in relation to the Master
Fund's liquidity needs and other factors and may make it particularly difficult
to establish the fair market value of particular securities from time to time.
The valuation of securities held by a Master Fund is the responsibility of the
Master Fund's Board of Trustees or Directors, acting in good faith and with
advice from the Advisor. (See "VALUATION OF SHARES.") Further, some attractive
equity securities may not be available to the Master Funds because foreign
shareholders hold the maximum amount permissible under current laws.
    
 
   
    Relative to the U.S. and to larger non-U.S. markets, many of the emerging
securities markets in which the Emerging Markets Series, Emerging Markets Small
Cap Series and Emerging Markets Value Fund may invest are relatively small, have
low trading volumes, suffer periods of illiquidity and are characterized by
significant price volatility. Such factors may be even more pronounced in
jurisdictions where securities ownership is divided into separate classes for
domestic and non-domestic owners. These risks are heightened for investments in
small company emerging markets securities.
    
 
    In addition, many emerging markets, including most Latin American countries,
have experienced substantial, and, in some periods, extremely high, rates of
inflation for many years. Inflation and rapid fluctuations in inflation rates
have had and may continue to have very negative effects on the economies and
securities markets of certain countries. In an attempt to control inflation,
wage and price controls have been imposed at times in certain countries. Certain
emerging markets have recently transitioned, or are in the process of
transitioning, from centrally controlled to market-based economies. There can be
no assurance that such transitions will be successful.
 
    Brokerage commissions, custodial services and other costs relating to
investment in foreign markets generally are more expensive than in the United
States; this is particularly true with respect to emerging markets. Such markets
have different settlement and clearance procedures. In certain markets there
have been times when settlements do not keep pace with the volume of securities
transactions, making it difficult to conduct such transactions. The inability of
a Master Fund to make intended securities purchases due to settlement problems
could cause the Master Fund to miss investment opportunities. Inability to
dispose of a portfolio security caused by settlement problems could result
either in losses to a Master Fund due to subsequent declines in value of the
portfolio security or, if the Master Fund has entered into a contract to sell
the security, could result in possible liability to the purchaser.
 
    The risk also exists that an emergency situation may arise in one or more
emerging markets as a result of which trading of securities may cease or may be
substantially curtailed and prices for a Master Fund's portfolio securities in
such markets may not be readily available. The Master Fund's portfolio
securities in the affected markets will be valued at fair value determined in
good faith by or under the direction of the Board of Trustees or Directors of
the relevant Master Fund.
 
                                       60
<PAGE>
    Government involvement in the private sector varies in degrees among the
emerging securities markets contemplated for investment by each Master Fund.
Such involvement may, in some cases, include government ownership of companies
in certain commercial business sectors, wage and price controls or imposition of
trade barriers and other protectionist measures. With respect to any developing
country, there is no guarantee that some future economic or political crisis
will not lead to price controls, forced mergers of companies, expropriation, the
creation of government monopolies, or other measures which could be detrimental
to the investments of a Master Fund.
 
   
    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 Lampur Stock Exchange, that operate to severely
constrain or prohibit foreign investors, including the corresponding Series in
which certain Portfolios invest their assets, from repatriating assets. While
there is some confusion in the market concerning the interpretations of these
changes, it appears that the Portfolios and Series will not be 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 Series have
stopped trading securities in Malaysia. With respect to the current Malaysian
investments owned by the Portfolios and Series, the Portfolios and Series are
presently valuing the securities in good faith at fair value by discounting 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 Series will treat their investments in Malaysian securities as
illiquid.
    
 
   
    As of the date of this prospectus, Malaysian securities constitute
approximately the following percentages of the net asset value of the designated
Series and Portfolios: Pacific Rim Series, 26.34%; International Small Company
Portfolio, 3.86%; DFA International Small Cap Value Portfolio, 2.25%; Emerging
Markets Series, 9.60%; Dimensional Emerging Markets Value Fund Inc. (Emerging
Markets Value Portfolio), 6.09%; and Emerging Markets Small Cap Series, 9.45%.
Malaysian securities constitute less than one percent of the net asset value of
the Large Cap International Portfolio and the RWB/DFA International High Book to
Market Portfolio.
    
 
   
    Taxation of dividends and capital gains received by non-residents varies
among countries with emerging markets and, in some cases, is high in relation to
comparable U.S. rates. Particular tax structures may have the intended or
incidental effect of encouraging long holding periods for particular securities
and/or the reinvestment of earnings and sales proceeds in the same jurisdiction.
In addition, emerging market jurisdictions typically have less well-defined tax
laws and procedures than is the case in the United States, and such laws may
permit retroactive taxation so that the Emerging Markets Series, Emerging
Markets Small Cap Series and Emerging Markets Value Fund could in the future
become subject to local tax liability that it had not reasonably anticipated in
conducting its investment activities or valuing its assets.
    
 
FOREIGN CURRENCIES AND RELATED TRANSACTIONS
 
   
    Investments of the International Equity Portfolios (directly or indirectly
through their investment in the Master Funds) and DFA Five-Year Global Fixed
Income Portfolio, many of the investments of the Two-Year Global Fixed Income
Series and, to a lesser extent, the investment in the Enhanced U.S. Large
Company Series, will be denominated in foreign currencies. Changes in the
relative values of foreign currencies and the U.S. dollar, therefore, will
affect the value of investments of these Portfolios and Master Funds. These
Portfolios and Master Funds may purchase foreign currency futures contracts and
options thereon in order to hedge against changes in the level of foreign
currency exchange rates. Such contracts involve an agreement to purchase or sell
a specific currency at a future date at a price set in the contract and enable
the Portfolios and Master Funds to protect against losses resulting from adverse
changes in the relationship between the U.S. dollar and foreign currencies
occurring between the trade and settlement
    
 
                                       61
<PAGE>
dates of Portfolio and Master Fund securities transactions, but they also tend
to limit the potential gains that might result from a positive change in such
currency relationships. Gains and losses on investments in futures and options
thereon depend on the direction of interest rates and other economic factors.
 
BORROWING
 
    Each Portfolio and each corresponding Master Fund, except the U.S. 9-10 and
Japanese Small Company Portfolios, DFA One-Year Fixed Income Portfolio, DFA
Five-Year Government Portfolio and DFA Intermediate Government Fixed Income
Portfolio, have reserved the right to borrow amounts not exceeding 33% of its
net assets for the purposes of making redemption payments. When advantageous
opportunities to do so exist, each Portfolio and each Master Fund may purchase
securities when borrowings exceed 5% of the value of its net assets. Such
purchases can be considered to be "leveraging" and, in such circumstances, the
net asset value of the Portfolio or Master Fund may increase or decrease at a
greater rate than would be the case if the Portfolio or Master Fund had not
leveraged. The interest payable on the amount borrowed would increase the
Portfolio's or Master Fund's expenses and, if the appreciation and income
produced by the investments purchased when the Portfolio or Master Fund has
borrowed are less than the cost of borrowing, the investment performance of the
Portfolio will be reduced as a result of leveraging.
 
PORTFOLIO STRATEGIES
 
    The method employed by the Advisor to manage the Domestic and International
Equity Portfolios (except U.S. Large Company Portfolio, Enhanced U.S. Large
Company Portfolio and their corresponding Series) and, in respect of those that
are Feeder Portfolios, the corresponding Master Funds, will differ from the
process employed by many other investment advisors in that the Advisor will rely
on fundamental analysis of the investment merits of securities to a limited
extent to eliminate potential portfolio acquisitions rather than rely on this
technique to select securities. Further, because securities generally will be
held long-term and will not be eliminated based on short-term price
fluctuations, the Advisor generally will not act upon general market movements
or short-term price fluctuations of securities to as great an extent as many
other investment advisors. U.S. Large Company Series will operate as an index
fund and, therefore, represents a passive method of investing in all stocks that
comprise the S&P 500 Index, which does not entail selection of securities based
on the individual investment merits of their issuers. The investment performance
of the U.S. Large Company Series and the corresponding Portfolio is expected to
approximate the investment performance of the S&P 500 Index, which tends to be
cyclical in nature, reflecting periods when stock prices generally rise or fall.
 
FUTURES CONTRACTS AND OPTIONS ON FUTURES
 
   
    U.S. Large Company Series, Enhanced U.S. Large Company Series, Large Cap
International Portfolio, the Value Series, the Tax Managed DFA International
Value Portfolio, DFA Real Estate Securities Portfolio, the International Value
Series, the Emerging Markets Series, the Emerging Markets Small Cap Series, the
DFA International Small Cap Value Portfolio and the Emerging Markets Value Fund
may invest in index futures contracts and options on index futures. 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 paid for open futures
options would exceed 5% of the Master Fund's or Portfolio's total 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%. Certain index futures contracts and options on index futures
may be considered to be derivative securities.
    
 
    These investments entail the risk that an imperfect correlation may exist
between changes in the market value of the stocks owned by the Portfolio or
Master Fund and the prices of such futures contracts
 
                                       62
<PAGE>
and options, and, at times, the market for such contracts and options might lack
liquidity, thereby inhibiting a Portfolio's or Master Fund's ability to close a
position in such investments. Gains or losses on investments in options and
futures depend on the direction of securities prices, interest rates and other
economic factors, and the loss from investing in futures transactions is
potentially unlimited. The Portfolio's and Master Fund's investment in futures
contracts and options are subject to special tax rules that may affect the
amount, timing and character of the income earned by the Portfolios and the
Master Funds, and the Portfolios' and the Master Funds' distributions to their
shareholders. (These special rules are discussed in the statement of additional
information.)
 
OPTIONS ON STOCK INDICES
 
    The Enhanced U.S. Large Company Series may purchase put and call options and
write put and call options on stock indices and stock index futures listed on
national securities exchanges or traded in the over-the-counter market. The
Enhanced U.S. Large Company Series may use these techniques to hedge against
changes in securities prices or as part of its overall investment strategy. An
option on an index is a contract that gives the holder of the option, in return
for a premium, the right to buy from (in the case of a call) or sell to (in the
case of a put) the writer of the option the cash value of the index at a
specified exercise price at any time during the term of the option. Upon
exercise, the writer of an option on an index is obligated to pay the difference
between the cash value of the index and the exercise price multiplied by the
specified multiplier for the index option. (An index is designed to reflect
specified facets of a particular financial or securities market, a specific
group of financial instruments or securities, or certain economic indicators.) A
stock index fluctuates with changes in the market values of the stocks included
in the index. Certain put and call options on stock indices and stock index
futures may be considered to be derivative securities.
 
    With respect to the writing of options, the writer has no control over the
time when it may be required to fulfill its obligation. Prior to exercise or
expiration, an option may be closed out by an offsetting purchase or sale of an
option on the same series. 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 may write covered straddles
consisting of a combination of a call and a put written on the same index. A
straddle will be covered when sufficient assets are deposited to meet the
Enhanced U.S. Large Company Series' immediate obligations. The Series may use
the same liquid assets to cover both the call and put options where the exercise
price of the call and the put are the same or the exercise price of the call is
higher than that of the put. In such cases, the Series will also segregate
liquid assets equivalent to the amount, if any, by which the put is "in the
money."
 
    The effectiveness of purchasing stock index options will depend upon the
extent to which price movements in the Enhanced U.S. Large Company Series'
portfolio correlate with price movements of the stock index selected. Because
the value of an index option depends upon movements in the level of the index
rather than the price of a particular stock, whether the Series will realize a
gain or loss from the purchase of options on an index depends upon movements in
the level of stock prices in the stock market generally or, in the case of
certain indices, in an industry or market segment, rather than movements in the
price of a particular stock. If the Enhanced U.S. Large Company Series takes
positions in options instruments contrary to prevailing market trends, the
Series could be exposed to the risk of a loss. Certain restrictions imposed on
the Enhanced U.S. Large Company Series by the Code may limit the ability of such
Series to invest in options.
 
SWAPS
 
    The Enhanced U.S. Large Company Series may enter into equity index swap
agreements for purposes of attempting to obtain a particular desired return at a
lower cost to the Series than if the Series had invested directly in an
instrument that yielded that desired return. Swap agreements are two-party
 
                                       63
<PAGE>
contracts entered into primarily by institutional investors for periods ranging
from a few weeks to more than one year. In a standard "swap" transaction, two
parties agree to exchange the returns (or differentials in rates of return)
earned or realized on particular predetermined investments or instruments. The
gross returns to be exchanged or "swapped" between the parties are generally
calculated with respect to a "notional amount," i.e., the return on or increase
in value of a particular dollar amount invested a group of securities
representing a particular index. Swap agreements are considered to be derivative
securities.
 
    The "notional amount" of the swap agreement is only a fictive basis on which
to calculate the obligations which the parties to a swap agreement have agreed
to exchange. Most swap agreements entered into by the Enhanced U.S. Large
Company Series would calculate the obligations of the parties to the agreement
on a "net basis." Consequently, the Series' current obligations (or rights)
under a swap agreement will generally be equal only to the net amount to be paid
or received under the agreement based on the relative values of the positions
held by each party to the agreement (the "net amount"). The Enhanced U.S. Large
Company Series' current obligations under a swap agreement will be accrued daily
(offset against amounts owed to the Series) and any accrued but unpaid net
amounts owed to a swap counterparty will be covered by the maintenance of a
segregated account consisting of liquid assets to avoid any potential leveraging
of the Series' portfolio. The Enhanced U.S. Large Company Series will not enter
into a swap agreement with any single party if the net amount owed or to be
received under existing contracts with that party would exceed 5% of the Series'
assets.
 
    Because they are two-party contracts and because they may have terms of
greater than seven days, swap agreements may be considered to be illiquid and,
therefore, swap agreements entered into by the Enhanced U.S. Large Company
Series and other illiquid securities will be limited to 15% of the net assets of
the Series. Moreover, the Enhanced U.S. Large Company Series bears the risk of
loss of the amount expected to be received under a swap agreement in the event
of the default or bankruptcy of a swap agreement counterparty. The Advisor will
cause the Enhanced U.S. Large Company Series to enter into swap agreements only
with counterparties that the Investment Committee of the Advisor has approved.
Certain restrictions imposed on the Enhanced U.S. Large Company Series by the
Code may limit the Series' ability to use swap agreements. The swap market is a
relatively new market and is largely unregulated. It is possible that
developments in the swaps market, including potential government regulation,
could adversely affect the Enhanced U.S. Large Company Series' ability to
terminate existing swap agreements or to realize amounts to be received under
such agreements.
 
BANKING INDUSTRY AND REAL ESTATE CONCENTRATIONS
 
    Concentrating in obligations of the banking industry may involve additional
risk by foregoing the safety of investing in a variety of industries. Changes in
the market's perception of the riskiness of banks relative to non-banks could
cause more fluctuations in the net asset value of the One-Year Fixed Income
Series and Two-Year Global Fixed Income Series (and, thus, DFA One-Year Fixed
Income Portfolio and DFA Two-Year Global Fixed Income Portfolio) than might
occur in less concentrated portfolios.
 
    The DFA Real Estate Securities Portfolio intends to concentrate its
investments in the real estate industry. Concentrating investments in the real
estate industry involves the risk of foregoing the safety of investing in a
variety of industries. Further, while the Portfolio will not invest in real
estate directly, but only in securities issued by real estate companies, the
Portfolio may be subject to certain risks that are similar to those associated
with the direct ownership of real estate in addition to securities markets
risks. These include declines in the value of real estate, risks related to
general and local economic conditions, heavy cash flow dependency, possible lack
of availability of mortgage funds, overbuilding, extended periods of high
vacancy rates, increases in property taxes and operating expenses, changes in
zoning laws, losses due to costs resulting from the clean-up of environmental
hazards, liability to third parties for damages resulting from environmental
hazards, casualty or condemnation losses, limitations on rents, and changes in
neighborhood values, interest rates and the credit quality of tenants. Also, in
deciding whether to purchase securities of a particular real estate company,
including REITS, the Advisor does not consider
 
                                       64
<PAGE>
the geographic location within the United States of the underlying assets of
such company. Therefore, to the extent that the Portfolio may become
substantially invested in real estate companies, including REITS, whose
underlying assets are located in one particular region of the United States and
subsequently a decline in real estate values occurs in that region, the value of
such real estate companies may be adversely affected and the Portfolio's net
asset value may in turn be similarly affected.
 
REPURCHASE AGREEMENTS
 
    In addition, all of the Portfolios and the Master Funds may invest in
repurchase agreements. In the event of the bankruptcy of the other party to a
repurchase agreement, the Fund or a Master Fund could experience delay in
recovering the securities underlying such agreements. Management believes that
this risk can be controlled through stringent security selection criteria and
careful monitoring procedures.
 
                             MANAGEMENT OF THE FUND
 
    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 Portfolios of the Fund 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 Underlying
Series 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 and, subject to this goal, may be placed with
brokers which have assisted in the sale of the Portfolios' shares.
 
    For the fiscal year ended November 30, 1997, (i) the Advisor (including a
sub-advisor in respect of DFA Real Estate Securities Portfolio) received a fee
for its services from the Fund or Master Funds which, on an annual basis,
equaled the following percentage of the average net assets of each Portfolio or,
in the case of a Feeder Portfolio, the average net assets of its corresponding
Master Fund; and (ii) the total expenses of each Portfolio were the following
percentages of respective average net assets:

(1) Prior to November 30, 1997, the U.S. 9-10 Small Company Portfolio invested

    as a shareholder of the Series, 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. Absent this arrangement, the annualized ratio of total
    operating expenses to average net assets for U.S. Large Company Portfolio
    for the fiscal year ended November 30, 1997, was 0.35%.
 
(3) 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 its 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. Absent this
    arrangement, the annualized ratio of total operating expenses to average net
    assets for the Enhanced U.S. Large Company Portfolio for the fiscal year
    ended November 30, 1997, was 0.54%.
 
(4) Effective December 20, 1996, the investment advisory fee payable by the Fund
    on behalf of the DFA Real Estate Securities Portfolio to the Advisor was
    reduced from .325% to .30% of the average net assets of the Portfolio on an
    annual basis. Effective December 11, 1996, the sub-advisory agreement
    between the Fund, on behalf of the Portfolio, and AEW terminated; pursuant
    to the terms of the sub-advisory agreement, the Portfolio paid AEW a fee
    equal to .175% of its average net assets on an annual basis.
 
(5) Effective August 9, 1996, the Advisor 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 Trust Series. For the fiscal year ended November 30, 1997,
    the Advisor was not required to waive any portion of its fee pursuant to
    such agreement.
 
(6) The Advisor provides asset allocation advice with respect to the Underlying
    Series to the International Small Company Portfolio without charge pursuant
    to a written agreement. The investment management fees applicable to each
    Underlying Series are equal to 0.10% of the average net assets of the Series
    on an annual basis. The International Small Company Portfolio, as a
    shareholder of each Underlying Series, benefits from the investment
    management services provided by the Advisor to each of the Underlying
    Series, and indirectly bears its proportionate share of the investment
    management fees paid by such Series. The Advisor has agreed to waive its
    administration fee and assume the direct
 
                                       66
<PAGE>
    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 Underlying Series. For the fiscal year ended November 30,
    1997, the Advisor was not required to waive any portion of its fee pursuant
    to such agreement.
 
    For purposes of waivers and/or expense assumptions, the annual expenses are
those expenses incurred in any period consisting of twelve consecutive months.
The Advisor retains the right in its sole discretion to modify or eliminate the
waiver of a portion of its fees or assumption of expenses in the future.
 
   
    With respect to the Emerging Markets Small Cap Portfolio, U.S. 4-10 Value
Portfolio, Emerging Markets Value Portfolio and the Tax Managed Portfolios and
Series, the investment management fees which the Portfolios and, with respect to
the Feeder Portfolios, the corresponding Master Funds are obligated to pay,
calculated as a percentage of the average net assets on an annual basis, are:
Emerging Markets Small Cap Series--.20%, U.S. 4-10 Value Series--.10%, Emerging
Markets Value Fund--.10%, Tax Managed U.S. 6-10 Small Company Portfolio--.50%,
Tax Managed U.S. 4-10 Value Portfolio--.50%, Tax Managed Large Cap Series--.20%,
and Tax Managed DFA International Value Portfolio--.50%.
    
 
    The Fund 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 the U.S. Large Company
Portfolio. Expenses allocable to a particular Portfolio or Series are so
allocated. The expenses of the Fund which are not allocable to a particular
Portfolio are to be borne by each Portfolio 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 Series on the basis of its relative
net assets.

 (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 Series, on an
     annual basis, exceeds 0.025% of the Portfolio's average net assets.

DIRECTORS AND OFFICERS
 
   
    The Board of Directors is responsible for establishing Fund policies and for
overseeing the management of the Fund. Each of the Directors and officers of the
Fund is also a Trustee and officer of the Trust and a Director and officer of
the Emerging Markets Value Fund. The Directors of the Fund, including all of the
disinterested directors, have adopted written procedures to monitor potential
conflicts of interest that might develop between the Feeder Portfolios and the
Master Funds. Information as to the Directors and officers of the Fund and the
Emerging Markets Value Fund and the Trustees and officers of the Trust is set
forth in the statement of additional information under "Directors and Officers."
    
 
                DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES
 
   
    Each Portfolio of the Fund intends to qualify each year as a regulated
investment company under the Code so that it will not be liable for U.S. federal
income taxes to the extent that its net investment income and net realized
capital gains are distributed. 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 and Tax Managed U.S. Large Cap
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 and Tax Managed
U.S. Large Cap 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 semi-annually by DFA Five-Year Government Portfolio. Any net
realized capital gains of Fixed Income Portfolios will be distributed annually
after the end of the fiscal year. Each Portfolio of the Fund is treated as a
separate corporation for U.S federal tax purposes.
    
 
   
    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 Value Portfolios
    
 
                                       70
<PAGE>
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.
 
    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.
 
    U.S. 6-10 Small Company, Enhanced U.S. Large Company, DFA One-Year Fixed
Income, DFA Two-Year Global Fixed Income, U.S. 9-10 Small Company, U.S. 4-10
Value, U.S. 6-10 Value, U.S. Large Cap Value, RWB/DFA International High Book to
Market and Emerging Markets Value Portfolios (collectively, the "Corporate
Feeder Portfolios") seek to achieve their investment objectives by investing all
of their investable assets in a corresponding Master Fund (collectively, the
"Corporate Master Funds"). The Corporate Master Funds intend to qualify each
year as regulated investment companies under the Code.
 
    A Corporate Feeder Portfolio receives income in the form of income dividends
paid by the corresponding Corporate Master Fund. This income, less the expenses
incurred in operations, is a Corporate Feeder Portfolio's net investment income
from which income dividends are distributed as described above. A Corporate
Feeder Portfolio also may receive capital gains distributions from the
corresponding Corporate Master Fund and may realize capital gains upon the
redemption of the shares of the corresponding Corporate Master Fund. Any net
realized capital gains of a Corporate Feeder Portfolio will be distributed as
described above.
 
   
    The U.S. Large Company, Tax Managed U.S. Large Cap Value, Emerging Markets,
Emerging Markets Small Cap, Japanese Small Company, Pacific Rim Small Company,
United Kingdom Small Company, Continental Small Company and International Small
Company Portfolios ("Partnership Feeder Portfolios"), seek to achieve their
investment objectives by investing all of their investable assets in a
corresponding Series of shares of the Trust or, in the case of International
Small Company Portfolio, the Underlying Series (collectively, the "Partnership
Series"). Each Partnership Series is classified as a partnership for U.S.
federal income tax purposes. A Partnership Portfolio is allocated its
proportionate share of the income and realized and unrealized gains and losses
of its corresponding Partnership Series.
    
 
    If a Portfolio, except for the Corporate and Partnership Feeder Portfolios,
purchases shares in certain foreign investment entities, called "passive foreign
investment companies" ("PFIC"), such Portfolio may be subject to U.S. federal
income tax and a related interest charge on a portion of any "excess
distribution" or gain from the disposition of such shares even if such income is
distributed as a taxable dividend by the Portfolio to its shareholders. In the
case of a Corporate Feeder Portfolio, if the corresponding Master Fund purchases
shares in PFICs, such Master Fund may be subject to U.S. federal income tax and
a related interest charge on a portion of any "excess distribution" or gain from
the disposition of such shares even if such income is distributed as a taxable
dividend by the Master Fund to the Corporate Feeder Portfolio. In the case of a
Partnership Feeder Portfolio, if the corresponding Partnership Series purchases
shares in PFICs, the Partnership Feeder Portfolio may be subject to U.S. federal
income tax and a related interest charge on a portion of any "excess
distribution" or gain from the disposition of such shares.
 
    The Portfolios (or, in the case of a Corporate or Partnership Feeder
Portfolio or International Small Company Portfolio, the corresponding Master
Funds) 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, or in the case of a Partnership Feeder Portfolio (but not a Corporate
Feeder Portfolio) its corresponding Master Fund, 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,
 
                                       71
<PAGE>
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.
 
    The Enhanced U.S. Large Company Series' investment in index derivatives are
subject to complex tax rules which may have the effect of accelerating income or
converting, in part, what otherwise would have been long-term capital gain into
short-term capital gain. These rules may affect the amount, character and timing
of income distributed to shareholders of the Enhanced U.S. Large Company
Portfolio.
 
   
    Since virtually all the net investment income from the Fixed Income
Portfolios is expected to arise from earned interest, it is not expected that
any of those Portfolios' distributions will be eligible for the dividends
received deduction for corporations. Similarly, it is anticipated that either
none or only a small portion of the distributions made by the International
Equity Portfolios will qualify for the corporate dividends received deduction
because of such Portfolios' investment in foreign equity securities. 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. The attempts of the Tax
Managed Portfolios and Series to time investments in order to tax manage the
minimization of dividends could result in the Tax Managed Portfolios or Series
being unable to flow through the corporate dividends received deduction on
stock. This will occur if they hold the stock for 45 days or less during the 90
day period that begins on the date that is 45 days before the date on which the
shares became ex-dividend with respect to such dividend. Preferred stock, if
any, must be held for more than 90 days during the 180 day period beginning 90
days before the ex-date to be eligible for pass-through of the dividends
received deduction.
    
 
   
    The Advisor seeks to manage each Tax Managed Portfolio or Series in order to
minimize the realization of net capital gains where possible and may minimize
taxable dividend distributions during a particular year. However, the
realization of capital gains and receipt of income is not entirely within the
Advisor's control and, for the tax reasons discussed above, each Tax Managed
Portfolio or Series will distribute substantially all of the net investment
income and net capital gains that it has realized on the sale of securities.
Thus, 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. Furthermore, the realization of capital
gains by a shareholder is dependent on the shareholder's purchase and redemption
activity. In the situation where a dividend option is available, if a
shareholder elects to receive capital gains distributions in cash, instead of
reinvesting them in additional shares, the capital at work in a Tax Managed
Portfolio or Series will be reduced. Also, purchases of shares in a Tax Managed
Portfolio or Series shortly before the record date for a dividend or capital
gains distribution may cause a portion of the investment to be returned to the
shareholder as a taxable distribution, regardless of whether the distribution is
being reinvested or paid in cash.
    
 
    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 Fund 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,
 
                                       72
<PAGE>
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 of the Fund. 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. 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 their own tax advisers concerning the
federal, state, local or foreign tax consequences of an investment in a
Portfolio.

Japanese Small Company Series, the Pacific Rim Small Company Series, the United
Kingdom Small Company Series, the Continental Small Company Series, DFA Two-Year

with PNC Bank, N.A.). The Chase Manhattan Bank serves as the custodian for the
Emerging Markets Series, Emerging Markets Small Cap Series and Dimensional
Emerging Markets Value Fund Inc., and PNC Bank, N.A. will serve as the custodian
for all of the Feeder Portfolios and the other Series of the Trust.
    
 
    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
 
                                       73
<PAGE>
purchased or redeemed directly from the Fund. Investors who are clients of
investment advisory organizations may also be subject to investment advisory
fees under their own arrangements with such organizations.
 
IN KIND PURCHASES
 
   
    If accepted by the Fund, shares of the 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 Fund
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.
    
 
   
    The Fund will not accept securities in exchange for shares of a Portfolio
unless: (1) such securities are, at the time of the exchange, eligible to be
included, or otherwise represented, in the Portfolio 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 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
Fund will accept such securities for investment and not for resale.
    
 
    A gain or loss for federal income tax purposes will generally be realized by
investors who are subject to federal taxation upon the exchange depending upon
the cost of the securities or local currency exchanged. Investors interested in
such exchanges should contact the Advisor. Purchases of shares will be made in
full and fractional shares calculated to three decimal places. In the interest
of economy and convenience, certificates for shares will not be issued.
 
                              VALUATION OF SHARES
 
   
    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 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 or Underlying Series in which such
Portfolios invest. Securities held by the Portfolios and 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, the U.S. Large Company Series, DFA Real Estate Securities Portfolio,
the Value Series, Emerging Markets Series, Emerging Markets Small Cap Series and
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
    
 
                                       74
<PAGE>
   
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 or Underlying Series), 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,
Master Fund or Underlying Series using the bid price 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 Fund 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
Transfer Agent has received the investor's purchase order in good order). "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 non-payment, the purchaser will be
responsible for any loss incurred by the Fund arising out of such cancellation.
To recover any such loss, the Fund reserves the right to redeem shares owned by
any purchaser whose order is canceled, and such purchaser may be prohibited or
restricted in the manner of placing further orders.
 
    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 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 Emerging Markets Value Fund in Approved Markets
may be subject to tax, investment and
    
 
                                       75
<PAGE>
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 Funds, 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 Funds.
 
    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
"In-Kind Purchases" and "DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES.") The
table in "SHAREHOLDER TRANSACTION 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 Fund 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 Underlying
Series. 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 rate
will be calculated by multiplying the rate of reimbursement fee of each
Underlying Series by a fraction equal to the portion of the assets of the
Portfolio which, at such time, is being allocated to each Underlying Series and
adding the results thereof. If there is a change to the reimbursement fee of an
Underlying Series during a quarter, the blended rate will be re-calculated to
reflect such change in the Underlying Series' reimbursement fee.

<PAGE>
    The public offering price of shares of the Domestic Equity Portfolios,
United Kingdom Small Company Portfolio, Large Cap International Portfolio,
RWB/DFA International High Book to Market 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.
 
                                  DISTRIBUTION
 
    The Fund acts as distributor of each series of its own shares of stock. It
has, however, entered into an agreement with DFA Securities Inc., a wholly owned
subsidiary of the Advisor, pursuant to which DFA Securities Inc. is responsible
for supervising the sale of each series of shares. No compensation is paid by
the Fund to DFA Securities Inc. under this agreement.
 
                               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 an Exchange Form and
mailing it to:
 
                       DFA Investment Dimensions Group Inc.
                       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 of the Fund 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 a portfolio of Dimensional
Investment Group Inc., an open-end, management investment company, subject to
the minimum purchase requirement set forth in that fund'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 prospectus 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 Fund, any
proposed exchange will be subject to the approval of the Advisor. Such approval
will depend on: (i) the size of the proposed exchange; (ii) the prior number of
exchanges by that shareholder; (iii) the nature of the underlying securities and
the cash position of the Portfolios involved in the proposed exchange; (iv) the
transaction costs involved in processing the exchange; and (v) the total number
of redemptions by exchange already made out of a Portfolio.
 
    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 an Exchange Form in good order.
Exchanges with respect to International Small Company Portfolio and any of the
Feeder Portfolios which invest in the Underlying Series are not subject to a
reimbursement fee. "Good order" means a completed Exchange Form specifying the
dollar amount to be exchanged, signed by all registered owners of the shares;
and if the Fund does not have on file the authorized signatures for the account,
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 the registrations of the two accounts are identical, stock
certificates have not been issued and the shares of the Portfolio being acquired
are registered in the investor's state of residence.
 
                                       77
<PAGE>
    There is no fee imposed on an exchange. However, the Fund reserves the right
to impose an administrative fee in order to cover the costs incurred in
processing an exchange. Any such fee will be disclosed in the prospectus. An
exchange is treated as a redemption and a purchase. Therefore, an investor could
realize a taxable gain or a loss on the transaction. The Fund reserves the right
to revise or terminate the exchange privilege, waive the minimum amount
requirement, limit the amount of or reject any exchange, as deemed necessary, at
any time.
 
                              REDEMPTION OF SHARES
 
    Investors who desire to redeem shares of a Portfolio must first contact the
Advisor at the telephone number shown under "PURCHASE OF SHARES." 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 Fund's 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
the Fund does not have on file the authorized signatures for the account, 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 on an authorization form filed
with the Fund, may request that redemption proceeds be paid in federal funds
wired to the bank they have designated on the authorization form. The Fund
reserves the right to send redemption proceeds by check in its discretion; a
shareholder may request overnight delivery of such check at the shareholder's
own expense. If the proceeds are wired to the shareholder's account at a bank
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 Fund reserves the
right at any time to suspend or terminate the redemption by wire procedure after
prior notification to shareholders. No charge is made by the Fund 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.") As of the date of this
prospectus, in the interests of economy and convenience, certificates for shares
will no longer be 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 Fund 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.
 
    With respect to each Portfolio, the Fund reserves 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 the Fund involuntarily redeems
shares from such an account and sends the proceeds to the stockholder, the Fund
will give written notice of the redemption to the stockholder at least sixty
days 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 the Fund 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 the
 
                                       78
<PAGE>
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.
 
   
    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 in accordance with Rule 18f-1 under the 1940 Act. 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 in accordance with Rule
18f-1 under the 1940 Act, when in the best interests of the Portfolio. 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' or Underlying Series'
investments, respectively) 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 when it is determined by the Advisor to be consistent with
the tax management strategies described in this prospectus.
    
 
   
    The Tax Managed Portfolios will value securities delivered in lieu of a cash
redemption at their most recent bid price. Securities may be selected due to tax
benefits that such an in kind distribution may generate for a Tax Managed
Portfolio. Using the bid price will reduce the net asset value remaining in such
Portfolio by the difference between the securities' bid price and their price
calculated as described under "Valuation of Shares." However, for tax purposes,
a portfolio does not realize gains or losses on in kind distributions. An in
kind distribution may benefit such Portfolio and corresponding Series by
reducing both brokerage and trading costs and unrealized gains or dividend
income.
    
 
                              GENERAL INFORMATION
 
   
    The Fund was incorporated under Maryland law on June 15, 1981. Until June
1983, the Fund was named DFA Small Company Fund Inc. The shares of each
Portfolio, when issued and paid for in accordance with the Fund'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 the Fund should occur, shareholders would be
entitled to receive on a per class basis the assets of the particular Portfolio
whose shares they own, as well as a proportionate share of Fund assets not
attributable to any particular class. Ordinarily, the Fund does not intend to
hold annual meetings of shareholders, except as required by the 1940 Act or
other applicable law. The Fund's bylaws provide that special meetings of
shareholders shall be called at the written request of 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 1940 Act, including semi-annual and annual financial statements of the Fund,
the latter being audited at least once each year.
 
   
    The DFA Investment Trust Company was organized as a Delaware business trust
on October 27, 1992. The Trust offers shares of its Series only to institutional
investors in private offerings. Dimensional Emerging Markets Value Fund was
incorporated under Maryland law on January 9, 1991, and offers its shares only
to institutional investors in private offerings. On November 21, 1997, the
shareholders of Dimensional Emerging Markets Value Fund approved the Fund's
conversion from a closed-end management investment company to an open-end
management investment company. The Fund may withdraw the
    
 
                                       79
<PAGE>
investment of a Feeder Portfolio in a Master Fund at any time, if the Board of
Directors of the Fund determines that it is in the best interests of the
Portfolio to do so. Upon any such withdrawal, the Board of Directors of the Fund
would consider what action might be taken, including the investment of all of
the assets of the Portfolio in another pooled investment entity having the same
investment objective as the Portfolio or the hiring of an investment advisor to
manage the Portfolio's assets in accordance with the investment policies
described above.
 
    Whenever a Feeder Portfolio, as an investor in its corresponding Master
Fund, is asked to vote on a shareholder proposal, the 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. If a majority shareholder of a Partnership Series of
the Trust redeems its entire interest in the Series, a majority in interest of
the remaining shareholders in the Series must vote to approve the continuing
existence of the Series or the Series will be liquidated.
 
   
    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 SEC 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 SEC 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 SEC 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 Fund's annual report to shareholders for
the fiscal year ended November 30, 1997 and semi-annual report to shareholders
for the period ended May 31, 1998 contain additional performance information. A
copy of the annual report is 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.

                        PORTFOLIO CHARACTERISTICS AND POLICIES


   
     The following information supplements the information set forth in the
prospectus under the captions "PORTFOLIO CHARACTERISTICS AND POLICIES - SMALL
COMPANY PORTFOLIOS," "INTERNATIONAL SMALL COMPANY PORTFOLIO - Investment
Objectives and Policies," "U.S. LARGE COMPANY PORTFOLIO - Investment Objective
and Policies," "ENHANCED U.S. LARGE COMPANY PORTFOLIO - Investment Objective and
Policies," "LARGE CAP INTERNATIONAL PORTFOLIO - Investment Objective and
Policies," "INVESTMENT OBJECTIVES AND POLICIES - FIXED INCOME PORTFOLIOS," "DFA
REAL ESTATE SECURITIES PORTFOLIO," "VALUE PORTFOLIOS - Portfolio Characteristics
and Policies," "RWB/DFA INTERNATIONAL HIGH BOOK TO MARKET PORTFOLIO - Investment
Objective and Policies," "TAX MANAGED DFA INTERNATIONAL VALUE PORTFOLIO -
Investment Objective and Policies," "EMERGING MARKETS PORTFOLIO, EMERGING
MARKETS SMALL CAP PORTFOLIO AND EMERGING MARKETS VALUE PORTFOLIO - Investment
Objectives and Policies" and "DFA INTERNATIONAL SMALL CAP VALUE PORTFOLIO -
Investment Objective and Policies."  The following information applies to all of
the Portfolios, except the Feeder Portfolios, and also to the Trust Series.
    

     Because the structure of the Domestic 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 Fund and the
issuer would be deemed "affiliated persons" under the Investment Company Act of
1940 (the "1940 Act") and certain requirements of the 1940 Act regulating
dealings between 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.

     Each of the International Equity Portfolios may invest up to 5% of its
assets in convertible debentures issued by non-U.S. companies.  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 so long as the Advisor anticipates such
stock will provide the Portfolio with opportunities which are consistent with
the Portfolio's investment objective and policies.

   
     The portfolio turnover rate for the U.S. 4-10 Value Series is anticipated
to be approximately 35%.  The portfolio turnover rate for the Tax Managed U.S.
4-10 Value Portfolio is anticipated to be approximately 60%.  Because the
relative market capitalizations of small companies compared with larger
companies generally do not change 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.  Generally, securities will be
purchased with the expectation that they will be held for longer than one year.
Generally, securities will be held until such time as, in the Advisor's
judgment, they are no longer considered an appropriate holding in light of the
policy of maintaining portfolios of companies with small market capitalization.
Because the DFA Real Estate Securities Portfolio generally will hold securities
for the long-term, its turnover rate ordinarily is anticipated  to be low.
Generally, securities will be purchased with the expectation that they will be
held for longer than one year.  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 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
certain 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 Underlying Series, respectively.

     The Fixed Income Portfolios acquire and sell securities on a net basis with
dealers which are major market markers 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


                                          4
<PAGE>

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, the DFA Real Estate Securities Portfolio, the Tax
Managed U.S. 4-10 Value Portfolio, the Tax Managed U.S. 6-10 Small Company
Portfolio, and the Tax Managed U.S. Large Cap 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 1997, 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 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 Fund. 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 Fund.

     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


                                          5
<PAGE>

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

               options thereon; and the Enhanced U.S. Large Company Portfolio
               may purchase, sell and enter into indices-related futures
               contracts, options on such futures contracts, securities-related
               swap agreements and other derivative instruments;

          (2)  make loans of cash, except through the acquisition of repurchase
               agreements and obligations customarily purchased by institutional
               investors; and, with respect to the Emerging Markets Value
               Portfolio, except through the acquisition of publicly-traded debt
               securities and short-term money instruments;

               securities of any issuer (except obligations of the U.S.
               Government and its instrumentalities) if, as a result, more than
               5% of the Portfolio's total assets, at market, would be invested
               in the securities of such issuer;  provided that this limitation
               applies to 100% of the total assets of the U.S. 9-10 Small

               Portfolio is not subject to this limitation;

               directors of the Fund or the Advisor owning more than 1/2 of 1%
               of such securities together own more than 5% of such securities;
               provided that the U.S. 4-10 Value, Tax Managed U.S. 4-10 Value,

               extraordinary or emergency purposes and then, in no event, in
               excess of 5% of a Portfolio's gross assets valued at the lower of
               market or cost; provided that each Portfolio, other than the U.S.

               in excess of 33% of the Fund's net assets valued at market;

   
          (6)  pledge, mortgage, or hypothecate any of its assets to an extent
               greater than 10% of its total assets at fair market value, except

               seven days, and other illiquid investments; provided that the

               of companies within such industry; except that (a) DFA One-Year

               Portfolios may acquire warrants as a result of corporate actions

               that the U.S. 4-10 Value Portfolio, Tax Managed U.S. 4-10 Value
               Portfolio, Tax Managed U.S. 6-10 Small Company Portfolio, Tax
               Managed U.S. Large Cap Value Portfolio, Tax Managed DFA

               U.S. 4-10 Value Portfolio, Tax Managed U.S. 4-10 Value Portfolio,
               Tax Managed U.S. 6-10 Small Company Portfolio, Tax Managed U.S.
               Large Cap Value Portfolio, Tax Managed DFA International Value
               Portfolio and Emerging Markets Value Portfolio are not subject to
               the limitation on selling securities short;
    

   
          (16) acquire more than 10% of the voting securities of any issuer;
               provided that (a) this limitation applies only to 75% of the
               assets of the DFA Real Estate Securities Portfolio, the Value
               Portfolios, the Emerging Markets Portfolio, the Emerging Markets
               Small Cap 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 Portfolio, Tax Managed DFA 
               International Value Portfolio and U.S. 9-10 Small Company 
               Portfolio are not subject to this limitation; or
    

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

     The investment limitations described in (3), (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 Underlying Series, 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


                                          8
<PAGE>

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 Fund's 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 or Underlying Series, respectively, 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 Series) 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. 
    

   
     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 U.S. 4-10 Value, Tax Managed U.S. 6-10 Small Company, Tax Managed 
U.S. Large Cap 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 or Underlying Series, as applicable) 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 or Underlying Series, as applicable) 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 RWB/DFA 
International High Book to Market Portfolio, the Tax Managed DFA 
International Value Portfolio and the DFA Real Estate Securities Portfolio 
(directly or indirectly through their investment in the Trust Series), 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 Emerging 
Markets 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 Series or the Emerging Markets Fund 
or whose use is otherwise considered by the Series or the Emerging Markets 
Fund to be advisable. Each Series or the Emerging Markets 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 Series 
will exclude from its total assets those assets which represent collateral 
received by the Portfolio or Series 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

                                          9
<PAGE>

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 
("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 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.

                                          10
<PAGE>

     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 Company Series would have to exercise those 
options which they have 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 Underlying 
Series.

   
     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 Funds will be 
required to make a margin deposit in cash or government securities with a 
broker


                                          11
<PAGE>

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 paid for open futures options would 
exceed 5% of the Master Fund's or Portfolio's total 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 applicable regulation, 
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.

                          FEDERAL TAX TREATMENT OF OPTIONS,
                       FUTURES CONTRACTS AND SIMILAR POSITIONS

     The investment by a Portfolio (or in the case of a Feeder Portfolio, by 
its corresponding Master Fund) and, in the case of the International Small 
Company Portfolio by the Underlying Series, in options, futures contracts and 
options on futures contracts is subject to many complex and special tax 
rules.  For example, options on stock and on narrow-based stock indexes will 
generally produce long-term or short-term capital gain or loss upon the 
exercise, lapse, or closing out of the option or sale of the underlying stock 
or security. By contrast, the treatment by a Portfolio or Master Fund of 
certain other options, futures and forward contracts is generally governed by 
Section 1256 of the Code. These "Section 1256" positions generally include 
listed options on debt securities, options on broad-based stock indexes, 
options on futures contracts, regulated futures contracts and certain foreign 
currency contracts and options thereon.

     Absent a tax election to the contrary, each such Section 1256 position 
held by a Portfolio or Master Fund will be marked-to-market (i.e., treated as 
if it were sold for fair market value) on the last business day of a 
Portfolio's or Master Fund's fiscal year, and all gain or loss associated 
with fiscal year transactions and marked-to-market positions at fiscal year 
end (except certain currency gain or loss covered by Section 988 of the Code) 
will generally be treated as 60% long-term capital gain or loss and 40% 
short-term capital gain or loss.  The effect of Section 1256 marked-to-market 
rules may be to accelerate income or to convert what otherwise would have 
been long-term capital gains into short-term capital gains or short-term 
capital losses into long-term capital losses within a Portfolio or Master 
Fund.  The acceleration of income on Section 1256 positions may require a 
Portfolio or Master Fund to accrue taxable income without the corresponding 
receipt of cash.  In order to generate cash to satisfy the distribution 
requirements of the Code, a Portfolio or Master Fund may be required to 
dispose of portfolio securities that it otherwise would have continued to 
hold or to use cash flows from other sources such as the sale of a 
Portfolio's or Master Fund's shares.  In these ways, any or all of these 
rules may affect both the amount, character and timing of income distributed 
to shareholders by a Portfolio.

                                          12
<PAGE>

     When a Portfolio (or in the case of a Feeder Portfolio, the Master Fund 
and, in the case of the International Small Company Portfolio, the Underlying 
Series) holds an option or contract which substantially diminishes a 
Portfolio's or Master Fund's risk of loss with respect to another position of 
a Portfolio or Master Fund (as might occur in some hedging transactions), 
this combination of positions could be treated as a "straddle" for tax 
purposes, resulting in possible deferral of losses, adjustments in the 
holding periods of a Portfolio's or Master Fund's securities and conversion 
of short-term capital losses into long-term capital losses.  Certain tax 
elections exist for mixed straddles (i.e., straddles comprised of at least 
one Section 1256 position and at least one non-Section 1256 position) which 
may reduce or eliminate the operation of these straddle rules.

     The Taxpayer Relief Act of 1997 has added new provisions for dealing 
with transactions that are generally called "Constructive Sale Transactions." 
Under these rules, a Portfolio or Series must recognize gain (but not loss) 
on any constructive sale of an appreciated financial position in stock, a 
partnership interest or certain debt instruments.  A Portfolio or Series will 
generally be treated as making a constructive sale when it:  1) enters into a 
short sale on the same property, 2) enters into an offsetting notional 
principal contract, or 3) enters into a futures or forward contract to 
deliver the same or substantially similar property.  Other transactions 
(including certain financial instruments called collars) will be treated as 
constructive sales as provided in Treasury regulations to be published.  
There are also certain exceptions that apply for transactions that are closed 
before the end of the 30th day after the close of the taxable year.

     A Portfolio (or in the case of a Feeder Portfolio, the Master Fund or 
Underlying Series) will monitor its transactions in such options and 
contracts and may make certain other tax elections in order to mitigate the 
effect of the above rules and to prevent disqualification of a Portfolio or 
Master Fund as a regulated investment company under Subchapter M of the Code.

                                  PURCHASE OF SHARES

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

     The Fund will accept purchase and redemption orders on each day that the 
New York Stock Exchange ("NYSE") is open for business, regardless of whether 
the Federal Reserve System is closed.  However, no purchases by wire may be 
made on any day that the Federal Reserve System is closed.  The Fund 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 is open on Good Friday and closed on Columbus Day and 
Veterans' Day.  Orders for redemptions and purchases will not be processed if 
the Fund is closed.  The TSE is closed on the following days in 1998: January 
1, 2, 3 and 15, February 11, March 21, April 29, May 3, 4 and 5, July 20, 
September 15 and 23, October 10, November 3 and 23 and December 23 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 Fund reserves the right, in its 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 the 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.  Based on the experience of the U.S. 9-10 Small Company Portfolio, 
management believes that any dilutive effect of the cost of investing the 
proceeds of the sale of the shares of that Portfolio is minimal and, 
therefore, the shares of that Portfolio are currently sold at net asset 
value, without imposition of a reimbursement fee.  Reimbursement fees may be 
charged prospectively from time to time based upon the future experience of 
the U.S. 9-10 Small Company Portfolio and other Portfolios.  Any such charges 
will be described in the prospectus.

                          REDEMPTION AND TRANSFER OF SHARES

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

     The Fund may suspend redemption privileges or postpone the date of 
payment: (1) during any period when the NYSE is closed, or trading on the 
NYSE is restricted as determined by the Commission, (2) during any period

                                          23
<PAGE>

when an emergency exists as defined by the rules of the Commission as a 
result of which it is not reasonably practicable for the Fund to dispose of 
securities owned by it, or fairly to determine the value of its assets and 
(3) for such other periods as the Commission may permit.

     Shareholders may transfer shares of any Portfolio to another person by 
making a written request therefore to the Advisor who will transmit the 
request to the Fund's 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.

                           CALCULATION OF PERFORMANCE DATA

     Following are quotations of the annualized percentage total returns for 
the one, five, and ten-year periods ended November 30, 1997 (as applicable) 
using 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.  Also included is a quotation of the 
annualized percentage total return for the DFA Two-Year Global Fixed Income 
Portfolio (for the period from February 9, 1996, the date of commencement of 
operations), the Enhanced U.S. Large Company Portfolio (for the period from 
July 3, 1996, the date of commencement of operations) and the International 
Small Company Portfolio (for the period from October 1, 1996, the date of 
commencement of operations) to November 30, 1997 using the standardized 
method of calculation required by the Commission.  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).

     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:

             n
     P(1 + T)  = 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).

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

     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


                                          25

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.
