RISK/RETURN SUMMARY
ABOUT THE PORTFOLIOS

THE PORTFOLIOS HAVE SPECIAL STRUCTURES: The Portfolios are "Feeder Portfolios"
- -- portfolios that do not buy individual securities directly.  Instead, they
invest in corresponding mutual funds called "Master Funds".  Master Funds in
turn purchase stocks, bonds and/or other securities.

POSSIBLE COMPLICATIONS:  The Master-Feeder structure is relatively new and more
complex.  While this structure is designed to reduce costs, it may not do so.
As a result, a Portfolio might encounter operational or other complications.

MANAGEMENT
Dimensional Fund Advisors Inc. (the "Advisor") is the investment manager for the
Master Funds.  (A Feeder Portfolio does not need an investment manager.)

EQUITY INVESTMENT APPROACH:

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


NO MARKET TIMING OR STOCK PICKING: In contrast to some other managers, the
Advisor does not take defensive positions in anticipation of negative investment
conditions, or try to pick potentially outperforming securities.

PORTFOLIO CONSTRUCTION: Generally, the Advisor structures a portfolio by:

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

2.   Creating a sub-set of companies meeting the Advisor's investment
     guidelines.

3.   Excluding certain companies after analyzing various factors (for example,
     solvency).

4.   Purchasing stocks so the portfolio is generally market cap weighted.

The U.S. Large Cap Value Portfolio III, the Tax-Managed U.S. Marketwide Value
Portfolio II and the Tax-Managed U.S. Marketwide Value Portfolio XI use a
market capitalization segmentation approach.  Broadly speaking, this
technique involves:

1.   Dividing all the companies traded on the New York Stock Exchange ("NYSE")
     into 10 groups or "deciles" based on market capitalization.  Stocks in
     decile 1 have the biggest market capitalizations and those in decile 10,
     the smallest.

2.   Combining two or more of these deciles into a market cap segment or range.


- -    A Master Fund buys securities directly.  A corresponding Feeder Portfolio
     invests in the Master Fund's shares.  The two have the same gross
     investment returns.

- -    Market Capitalization means the number of shares of a company's stock
     outstanding times price per share.

- -    Market Capitalization Weighted means the amount of a stock in an index or
     portfolio is keyed to that stock's market capitalization compared to all
     eligible stocks.   The higher the stock's relative market cap, the greater
     its representation.


                                          1
<PAGE>


3.   Generally considering a stock (it may not necessarily be NYSE traded) for
     purchase only if its market capitalization falls within the range created.

For example, the U.S. Large Cap Value Portfolio III buys stock with market caps
in the range defined by stocks in NYSE deciles 1 through 5.


TAX-MANAGED PORTFOLIO STRATEGIES:

The Advisor's tax management strategies are designed to minimize taxable
distributions to shareholders.  Generally, the Advisor buys and sells a tax-
managed portfolio's securities with the goals of:

1.   Delaying and minimizing the realization of net capital gains
     (e.g., appreciated stocks might be sold later).


2.   Maximizing the extent to which any realized net capital gains are long-term
     in nature (i.e., taxable at lower capital gains tax rates).

3.   Minimizing dividend income.


4.   Sell securities to other tax-managed portfolios in order to offset gains
     by realized losses.


MARKET RISK:  Even a long-term investment approach cannot guarantee a profit.
Economic, political and issuer specific events will cause the value of
securities, and the Portfolios that own them, to rise or fall.

INVESTMENT OBJECTIVES, STRATEGIES AND RISKS

DFA INTERNATIONAL VALUE PORTFOLIO III

- -    INVESTMENT OBJECTIVE: Long-term capital appreciation.

- -    Investment Strategy: Purchase a Master Fund that buys Value Stocks or
     large non-U.S. companies on a market capitalization weighted basis in
     each applicable country.

- -    Shareholders of Tax-Managed Value Portfolios may save on
     taxes while they hold their shares. However, they will still have to
     pay taxes if they sell their shares at a profit.

- -    DFA International Value Portfolio III's foreign currency risks generally
     are not hedged.




                                          2
<PAGE>




FOREIGN SECURITIES AND CURRENCIES RISK: Foreign securities prices may decline or
fluctuate because of: (a) economic or political actions of foreign governments,
and/or (b) less regulated or liquid securities markets.  Investors holding these
securities are also exposed to foreign currency risk (the possibility that
foreign currency will fluctuate in value against the U.S. dollar).  Foreign
currency risk can be minimized by hedging.  However, hedging may be expensive.


U.S. LARGE CAP VALUE PORTFOLIO III
TAX-MANAGED U.S. MARKETWIDE VALUE PORTFOLIO II
TAX-MANAGED U.S. MARKETWIDE VALUE PORTFOLIO XI


   INVESTMENT OBJECTIVES:

   -U.S. Large Cap Value Portfolio III: Long-term capital appreciation
   -Tax-Managed U.S. Marketwide Value Portfolios: Long-term capital
   appreciation while minimizing federal income taxes on returns.


   -Investment Strategy (each Portfolio): Purchase a Master Fund that buys
   value stocks of United States companies or a market capitalization
   weighted basis.

   -How the Portfolios Differ: The Portfolios focus on different parts of the
   value stocks universe.


   -U.S. Large Cap Value Portfolio III - Large capitalization stocks.
   -Tax-Managed U.S. Marketwide Value Portfolios - The full universe except
   for very small stocks.


   Only the Tax-Managed Value Portfolios employ the Advisor's tax management
   strategies.

OTHER RISKS

DERIVATIVES:

Derivatives are securities, such as futures contracts, whose value is derived
from that of other securities or indices.  Derivatives can be used for hedging
(attempting to reduce risk by offsetting one investment position with another)
or speculation (taking a position in the hope of increasing return).  The Master
Fund in which DFA International Value Portfolio III invests may use long-term
foreign currency futures contracts to hedge foreign currency risks.  Hedging
with derivatives may increase expenses, and there is no guarantee that a hedging
strategy will work.

INTRODUCTION OF THE EURO:

On January 1, 1999, The European Monetary Union ("EMU") introduced a common
currency, the Euro, replacing its members' national currencies. This development
may affect DFA International Value Portfolio III (the Master Fund it buys may
invest in EMU countries) to the extent it changes investment practices,
opportunities, risks and investor behavior or creates administrative problems.
The Advisor and its global custodians are attempting to assure on an ongoing
basis that the Portfolio and Master Fund remain




                                          3
<PAGE>


unaffected by any transition related disruptions. However, they cannot
guarantee that their efforts will succeed completely. The relative value of
the U.S. dollar and Euro will fluctuate.  Accordingly, currency risk
(discussed above) will continue to apply to any exposure the Portfolio may
have (through the Master Fund) to investments in EMU countries.

SECURITIES LENDING:

The Master Funds purchased by the Portfolios may lend their portfolio
securities to generate additional income.  If they do so, they will use
various strategies (for example, only making fully collateralized and bank
guaranteed loans) to reduce related risks.

YEAR 2000 ISSUE:

Unless modified, many computer programs will not properly process information
from the year 2000 on.  While the issue is international in scope, there is
particular concern with foreign entities.  The Advisor has taken steps
designed to ensure that its computers and those of Portfolio and Master Fund
service providers (e.g., custodians) will operate properly.  Portfolios and
Master Funds may be negatively affected if the Advisor's efforts prove
inadequate, and/or year 2000 problems hurt portfolio securities or economic
conditions generally.



VALUE STOCKS:

Compared to other stocks, value stocks sell for low prices relative to their
earnings dividends or book value. In selecting value stocks, the Advisor
primarily considers price relative to book value.

RISK AND RETURN BAR CHARTS AND TABLES

The Bar Charts and Table below illustrate the variability of each Portfolio's
returns and is meant to provide some indication of the risks of investing in the
Portfolios.  Shown are changes in performance from year to year, and how annual
returns for 1, 5, and 10 years compare with those of a broad measure of market
performance.  Past performance is not an indication of future results.
The Tax-Managed Value Portfolios have not been in operation for a full
calendar year so no information is shown for them.

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

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

MANAGEMENT AND ADMINISTRATIVE SERVICES

     Dimensional Fund Advisors Inc. (the "Advisor" or "DFA") provides each
Portfolio with administrative services and also serves as investment advisor to
each Master Fund.  (See "MANAGEMENT OF THE PORTFOLIOS.")

DIVIDEND POLICY

     Each Portfolio distributes dividends from its net investment income in
December of each year and will distribute any realized net capital gains
annually after the end of the Fund's fiscal year in November.  (See "DIVIDENDS,
CAPITAL GAINS DISTRIBUTIONS AND TAXES.")

PURCHASE, VALUATION AND REDEMPTION OF SHARES

     The shares of the Portfolios are offered at net asset value, which is
calculated as of the close of the NYSE on each day that the NYSE is open for
business.  The value of a Portfolio's shares will fluctuate in relation to the
investment experience of its corresponding Master Fund.  The redemption price of
a share of each Portfolio is equal to its net asset value.  (See "PURCHASE OF
SHARES," "VALUATION OF SHARES" and "REDEMPTION OF SHARES.")

                          INVESTMENT OBJECTIVES AND POLICIES

DFA INTERNATIONAL VALUE PORTFOLIO III

     The investment objective of the DFA International Value Portfolio III 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 invests in the stocks of large non-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,
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, as described
below, will be considered eligible for investment. In measuring value, the
Advisor may consider additional factors such as cash flow, economic
conditions and

                                          8
<PAGE>

developments in the issuer's industry.  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,
Austria, Belgium, Denmark, Finland, France, Germany, Hong Kong, Ireland,
Italy, Japan, the Netherlands, New Zealand, Norway, Singapore, Spain, Sweden,
Switzerland and the United Kingdom.  As the International Value Series' asset
growth permits, it may invest in the stocks of large companies in other
developed markets.

PORTFOLIO CONSTRUCTION

     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.  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.  The International
Value Series reserves the right to invest in futures contracts and options on
futures contracts to commit funds awaiting investment or to maintain liquidity.
To the extent that the International Value Series invests in futures contracts
and options thereon for other than bona fide hedging purposes, it will not
purchase futures contracts or options thereon if, as a result, more than 5% of
its net assets would then consist of initial margin deposits and premiums
required to establish such positions.

     In determining market capitalization weights, the Advisor, using its best
judgment, will seek to eliminate the effect of cross holdings on the individual
country weights.  As a result, the weighting of certain countries in the
International Value Series may vary from their weighting in international
indices, such as those published by The Financial Times, Morgan Stanley Capital
International or Salomon/Russell.  The Advisor, however, will not attempt to
account for cross holding within the same country.

     It is management's belief that the value stocks of large companies offer,
over a long term, a prudent opportunity for capital appreciation but, at the
same time, selecting a limited number of large company stock for inclusion in
the International Value Series involves greater risk than including a large
number of them.

MALAYSIAN SECURITIES

     As of September 10, 1998, the International Value Series discontinued
further investment in Malaysian securities as a consequence of certain
restrictions imposed by the Malaysian government on the repatriation of assets
by foreign investors such as the Series.

     On September 1, 1998, the Malaysian government announced a series of
capital and foreign exchange controls on the Malaysian currency, the ringgit,
and on transactions on the Kuala Lumpur Stock Exchange, that operated to
severely constrain or prohibit foreign investors, including the Series, from
repatriating assets.  Pursuant to these regulations, the Series was not
permitted to convert the proceeds of the sale of its Malaysian investments into
U.S. dollars prior to September 1, 1999.


     As a consequence of these developments, the International Value Series
stopped trading securities in Malaysia effective September 10, 1998.  On
February 4, 1999, the Malaysian government announced the imposition of a levy
on repatriation of portfolio capital.  The levy replaced the 12-month holding
period imposed under the September 1, 1998 exchange control rules.  The
amount of the levy depends on the duration that funds have been held in
Malaysia.  With respect to funds invested in Malaysia prior to February 15,
1999, which includes all the funds so invested by the Master Funds, profits
from investment made during the 12-month holding period are exempt from
imposition of a levy.  A levy will be imposed, however, on the amount of
capital that is repatriated. Currently, principal amounts repatriated within
one year of the date of their initial investment are subject to the levy at a
decreasing rate. It is anticipated that a levy will no longer be imposed
after September 1, 1999, at which time the Malaysian authorities will
implement a capital gains tax.


                                          9
<PAGE>

     The International Value Series is presently valuing the Malaysian
investments at the current market prices of the securities and discounting
the U.S. dollar-ringgit currency exchange rate. The Series considers its
Malaysian investments to be liquid, as a result of transactions where
Malaysian investments have been successfully sold, and also because of
changes in the Malaysian regulatory environment. It is impossible to predict
future events in Malaysia and what, if any, further actions the Malaysian
government may take that may impact the Malaysian investments of the
International Value Series. The Advisor is closely monitoring the situation,
and will continue to manage the Malaysian investments in the best interests
of investors. As of June 7, 1999, Malaysian securities constituted
approximately 0.37% of the net asset value of the International Value Series.



THE U.S. LARGE CAP VALUE PORTFOLIO

     The investment objective of the U.S. Large Cap Value Portfolio III (the
"U.S. Value Portfolio") is to achieve long-term capital appreciation.  The
U.S. Value Portfolio invests all of its assets in the U.S. Large Cap Value
Series III (the "U.S. Value Series") of the Trust, which has the same
investment objective and policies as the U.S. Value Portfolio.



     The U.S. Value Series invests in the common stocks of large U.S. companies
with shares that have a high book to market ratio.  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 below, will be considered eligible for investment.  The U.S. Value
Series will purchase common stocks of companies whose market capitalization
(i.e., the market price of its common stock multiplied by the number of
outstanding shares) equals or exceeds that of the company having the median
market capitalization of companies whose shares are listed on the NYSE.  In
addition, the U.S. Value 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 U.S. Value Series' net
assets at the time of purchase.


     PORTFOLIO CONSTRUCTION


     Ordinarily, at least 80% of the assets of the U.S. Value Series will be
invested in a broad and diverse group of readily marketable common stocks of
large U.S. companies with high book to market ratios, as described above.
The U.S. Value Series may invest in futures contracts and options on futures
contracts.  To the extent that the U.S. Value Series invests in futures
contracts and options thereon for other than bona fide hedging purposes, it
will not purchase futures contracts or options thereon, if, as a result, more
than 5% of its net assets would then consist of initial margin deposits and
premiums required to establish such positions.  The U.S. Value Series will
purchase securities that are listed on the principal U.S. national securities
exchanges and traded over-the-counter.



     It is management's belief that the stocks of large U.S. 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 U.S. Value Series involves greater risk than including a
large number of them.

TAX-MANAGED VALUE PORTFOLIOS

      The investment objective of the Tax-Managed U.S. Marketwide Value
Portfolios II and XI (the "Tax-Managed Value Portfolios") is to achieve
long-term capital appreciation.  The Tax-Managed Value Portfolios will pursue
their investment objectives by investing all of their assets in the
Tax-Managed U.S. Marketwide Value Series and the Tax-Managed U.S. Marketwide
Value Series X (collectively, the "Tax-Managed Value Series") of the Trust,
respectively. Each Tax-Managed Value Series has the same investment objective
and policies as the corresponding Tax-Managed Value Portfolio.



  Ordinarily, each Tax-Managed Value Series 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 the
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 ration if the ratio equals or exceeds the ratio 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 "Porfolio
Structure," will be considered eligible for investment. In measuring value,
however, the Advisor may consider additional factors such as a company's cash
flow, economic conditions and developments in the company's industry. The
Tax-Managed Value Series will purchase common stocks of companies whose
market capitalizations equal the market capitalizations of companies in the
1st through 8th deciles of those companies listed on the NYSE.



PORTFOLIO CONSTRUCTION

      Each of the Tax-Managed Value Series will purchase securities that are
listed on the principal U.S. national securities exchanges and traded OTC.
Each such Series intends to invest in a large portion of the universe of
companies whose shares are eligible for investment; shares of a certain
number of eligible companies will be held in both such Series. It is intended,
for example, that the securities portfolio of the Tax-Managed U.s. Marketwide
Value Series will not be identical to that of the Tax-Managed U.S. Marketwide
Value Series X even though the investment criteria of each Series are the same.



     The Tax-Managed 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. In addition, the Series may sell portfolio Securities when their
book to market ratios fall substantially below that of the security with the
lowest such ratio that is then eligible for purchase by the Series.


TAX MANAGEMENT STRATEGIES

     The Tax-Managed Value Series seek to minimize the impact of federal
taxes on investment 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, a Tax-Managed Value 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
generally 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 Value Series, when possible, will refrain from
disposing of a security until the long-term holding period for capital gains
for tax purposes has been satisfied. Additionally, each Series, when
consistent with all other tax management policies, may sell securities in
order to realize capital losses. Realized capital losses can be used to
offset realized capital gains, thus reducing capital gains distributions. In
addition to selling practices used among all Portfolios and Series managed by
the Advisor, the Tax-Managed


                                          11
<PAGE>


U.S. Marketwide Value Series may sell portfolio securities to Tax-Managed
U.S. Marketwide Value Series X (and vice versa). Such sales would be made to
realize losses on securities which would be used to offset gains on other
securities realized by the selling Series. Such transactions are intended to
benefit both Series that are purchasing Series will acquire an eligible
portfolio security, at a current market price, but without payment of
brokerage commissions.



While the Advisor believes this strategy can be both tax and cost efficient,
applicable federal tax law provides for suspension of recognition of losses
and potential disallowance of such losses incurred on the sale of securities
by a Series to a Series, if, as of the date of any sale of a loss security,
five or fewer persons own or are considered for tax purposes to own more than
50% of the outstanding shares of both the selling and purchasing Series'
corresponding Tax-Managed Value Portfolios. The Advisor intends to control
the number of investors in each Tax-Managed Value Portfolio in two ways.
First as with all portfolios that the Advisor manages, it retains the right
in its discretion to reject any initial or additional investment for any
reason and to suspend the offering of shares of any portfolio. Second, the
Advisor intends to offer the shares of each Tax-Managed Value Portfolio to
relatively few institutioanl investors and anticipates that shares will be
offered primarily to individual investors, thereby creating a substantial
number of shareholders in each Tax-Managed Value Portfolio. Finally, the
Advisor intends to monitor closely all purchases of shares of both
Tax-Managed Value Portfolios in order to increase the probability that the
five or fewer shareholder threshold is not violated.




The timing of purchases and sales of securities may be managed to minimize
the receipt of dividends when possible.  With respect to dividends that are
received, the Tax-Managed Value Series and Portfolios may not be eligible to
flow through the dividends received deduction attributable to holdings in
U.S. equity securities to corporate shareholders if, because of timing
activities, the requisite holding period of the dividend paying stock is not
met.  Portfolio investments also may be managed to emphasize low-dividend
yielding securities.





     The Tax-Managed Value Series are expected to deviate from their market
capitalization weightings to a greater extent than the other Series described
in this Prospectus.  For example, the Advisor may exclude the stock of a
company that meets applicable market capitalization criteria in order to
avoid dividend income, and may sell the stock of a company that meets
applicable market capitalization criteria in order to realize a capital loss.
 Also, while other Series are managed with the expectation that securities
generally will be held for longer than one year, the Tax-Managed Value Series
may dispose of securities whenever the Advisor determines that disposition is
consistent with their tax management strategies or is otherwise in the best
interests of the Tax-Managed Value Series.




     Although the Advisor intends to manage each Tax-Managed Value Series in
a manner to minimize the realization of capital gains and taxable dividend
income each year, the Tax-Managed Value Portfolios may nonetheless distribute
taxable gains and dividends to shareholders. Of course, 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 Tax-Managed Series realizes a net
capital loss. Furthermore, the redeeming shareholders will be required to pay
taxes on their capital gain, if any, on a redemption of a Portfolio's shares,
whether paid in cash or in kind, if the amount received on redemption is
greater than the amount of the shareholder's tax basis in the shares redeemed.




                                          12

<PAGE>


                                 EQUITY PORTFOLIOS


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



                    DEVIATION FROM MARKET CAPITALIZATION WEIGHTING

     The Master Funds are market capitalization weighted.  That is, each
security is purchased based on the issuer's relative market capitalization.
In this way, the amount of a particular security owned by a Master Fund is
keyed to that security's market capitalization compared to all securities
eligible for purchase.  Deviation from strict market capitalization weighting
may occur for several reasons.  The Advisor may exclude the stock of a
company that meets applicable market capitalization criterion if the Advisor
determines in its best judgment that the purchase of such stock is
inappropriate given other conditions.  (The Advisor does not anticipate that
a significant number of securities which meet the market capitalization
criteria will be selectively excluded.)  Deviation also will occur because
the Advisor intends to purchase in round lots only.  Furthermore, the Advisor
may reduce the relative amount of any security held from the level of strict
adherence to market capitalization weighting, in order to retain sufficient
portfolio liquidity.  A portion, but generally not in excess of 20% of assets
may be invested in interest bearing obligations, such as money market
instruments, thereby causing further deviation from strict market
capitalization weighting.  A further deviation may occur due to investments
in privately placed convertible debentures.


     The Tax-Managed Value Series should not be expected to adhere to their
market capitalization weightings to the same extent as the other Series. The
tax management strategies used by the Advisor to defer the realization of net
capital gains or minimize dividend income from time to time, may cause
deviation from market capitalization weighting.



     Block purchases of eligible securities may be made at opportune prices even
though such purchases exceed the number of shares which, at the time of
purchase, strict adherence to the policy of market capitalization weighting
would otherwise require.  In addition, securities eligible for purchase or
otherwise represented in a portfolio may be acquired in exchange for the
issuance of shares.  (See "PURCHASE OF SHARES--In Kind Purchases.")  While such
transactions might cause a temporary deviation from market capitalization
weighting, they would ordinarily be made in anticipation of further growth of
assets.

     Changes in the composition and relative ranking (in terms of market
capitalization) of the stocks which are eligible for purchase take place with
every trade when the securities markets are open for trading due, primarily, to
price fluctuations of such securities.  On at least a semi-annual basis, the
Advisor will prepare lists of companies with high book to market ratios whose
stock is eligible for investment by each Master Fund.  Only common stocks whose
market capitalizations are at or above the minimum on such list will be
purchased.  Additional investments generally will not be made in securities
which have depreciated in value sufficiently that they are not then considered
by the Advisor to be large companies.  This may result in further deviation from
strict market capitalization weighting.  Such deviation could be substantial if
a significant amount of a portfolio's holdings decrease in value sufficiently to
be excluded from the requirement for eligible securities, but not by a
sufficient amount to warrant their sale.

                                   SECURITIES LOANS

     The Master Funds are authorized to lend securities to qualified brokers,
dealers, banks and other financial institutions for the purpose of earning
additional income.  While a Master Fund may earn additional income from lending
securities, such activity is incidental to a Master Fund's investment objective.
The value of securities loaned may not exceed 33 1/3% of the value of a Master
Fund's total assets.  In connection with such loans, a 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, a Master Fund will be able
to terminate the loan at any time and will receive reasonable interest on the
loan, as well as amounts equal to any dividends, compensation or other
distributions on the loaned securities.  In the event of the bankruptcy of the
borrower, a Master Fund could experience delay in recovering the loaned
securities.  Management believes that this risk can be controlled through
careful monitoring procedures.  Each Portfolio is also authorized to lend its
portfolio securities.  However, as long as it holds only shares of its
corresponding Master Fund, it will not do so.

                             MANAGEMENT OF THE PORTFOLIOS

     The Advisor serves as investment advisor to each Master Fund.  As such, it
is responsible for the management of their respective assets.  Investment
decisions for the 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 each
Master Fund with a trading department and selects brokers and dealers to effect
securities transactions.

     Securities transactions are placed with a view to obtaining the best price
and execution of such transactions.  The Advisor is authorized to pay a higher
commission to a broker, dealer or exchange member than another such organization
might charge if it determines, in good faith, that the commission paid is
reasonable in relation to the research or brokerage services provided by such
organization.


     For the advisory fees that the Portfolios have incurred for the fiscal
year, see "ANNUAL FUND OPERATING EXPENSES."  The Advisor was organized in
May, 1981, and is engaged in the business of providing investment management
services to institutional investors.  Assets under management total
approximately $28 billion.


     The Fund and the Trust bear all of their own costs and expenses,
including: services of its independent accountants, legal counsel, brokerage
commissions and transfer taxes in connection with the acquisition and
disposition of portfolio securities, taxes, insurance premiums, costs
incidental to meetings of its shareholders and directors or trustees, the
cost of filing its registration statements under federal securities laws and
the cost of any filings required under state securities laws, reports to
shareholders, and transfer and dividend disbursing agency, administrative
services and custodian fees.  Expenses allocable to a particular Portfolio or
Master Fund are so allocated.  Expenses which are not allocable to a
particular Portfolio or Master Fund are borne by each Portfolio and Master
Fund on the basis of their relative net assets.

CONSULTING SERVICES - INTERNATIONAL VALUE SERIES

     The Advisor has entered into a Consulting Services Agreement with
Dimensional Fund Advisors Ltd. ("DFAL") and DFA Australia Limited ("DFA
Australia"), respectively.  Pursuant to the terms of each Consulting Services
Agreement, DFAL and DFA Australia provide certain trading and administrative
services to the Advisor with respect to the International Value Series of the
Trust.  The Advisor owns 100% of the outstanding shares of DFAL and
beneficially owns 100% of DFA Australia.

                   DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES

     Each Portfolio distributes substantially all of its net investment income
in December of each year.  Each Portfolio will distribute any realized net
capital gains annually after the end of the Fund's fiscal year.

                                          14
<PAGE>


     Special tax rules may apply in determining the income and gains that each
Master Fund earns on its investments.  These rules may affect the amount of
distributions that a Portfolio pays to its shareholders.



     Shareholders of the Portfolios will automatically receive all income
dividends and any 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).  Shareholders of the Portfolios, except
the DFA International Value Portfolio III, who do not own their shares under a
401(k) plan, may select one of the following options upon written notice to
PFPC Inc., the transfer agent for each Portfolio:



          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.

     Each Portfolio receives income in the form of income dividends paid by the
corresponding Master Fund.  This income, less the expenses incurred in
operations, is a Portfolio's net investment income from which income dividends
are distributed as described above.  A Portfolio also may receive capital gains
distributions from the corresponding Master Fund and may realize capital gains
upon the redemption of the shares of the Master Fund.  Any net realized capital
gains of a Portfolio will be distributed as described above.  Dividends and
distributions paid to a 401(k) plan accumulate free of federal income taxes.


     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 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. Dividends from net investment income of U.S. Large Cap
Value Portfolio III, Tax-Managed U.S. Marketwide Value Portfolio II and
Tax-Managed U.S. Marketwide Value Portfolio XI 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 corresponding Master Fund from domestic (U.S.) sources.  Each
Tax-Managed Value Series' attempts to time investments in order to minimize
receipt of dividends could result in the Series being unable to flow through
the dividends received deduction to corporate shareholders. This will occur
if Tax-Managed Value Series does not hold the stock of a domestic (U.S.)
corporation for the requisite holding period to be eligible for pass-through
of the dividends received deduction.  It is anticipated that either none or
only a small portion of the distributions made by the DFA International Value
Portfolio III will qualify for the corporate dividends received deduction
because of its corresponding Master Fund's investment in foreign equity
securities.



     For those investors subject to tax, if purchases of shares of the
Portfolios 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.  Dividends from net investment income or net short-term capital
gains will be taxable as ordinary income.  Shareholders are notified annually by
the Fund as to the federal tax status of dividends and distributions paid by the
Portfolios.



     The Advisor seeks to manage the Tax-Managed Value Series in order to
minimize the realization of net capital gains and taxable dividend income
during a particular year.  However, the realization of capital gains and
receipt of income is not entirely within the Advisor's control.  Thus, the
Tax-Managed Value Portfolios may nonetheless distribute taxable gains and
dividends to shareholders. Capital gains distributions may vary considerably
from year to year. There will be no capital gains distributions in years
when a Tax-Managed Value Series realizes a net capital loss. Furthermore, the
realization of capital gains by a shareholder on the sale of portfolio shares
will depend on whether his or her redemption price exceeds his or her tax
basis in the shares sold.



                                          15

<PAGE>


     Dividends which are declared in November or December to shareholders of
record in such month but which, for operational reasons, may not be paid to the
shareholder until the following January, will be treated for tax purposes as if
paid by a 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 of a
Portfolio for shares of another portfolio 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.

     Certain investments by the Master Funds may be subject to special rules
which may affect the amount, character and timing of the income to the Master
Fund.  Some of these rules are referenced in the statement of additional
information.  Specifically, prospective investors should consult the statement
of additional information for further information regarding the extent to which
distributions from a portfolio may be eligible for the dividends received
deduction or whether certain foreign tax credits may be available to an investor
in a Portfolio.

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

     The Portfolios are 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 the
Portfolios.

                                  PURCHASE OF SHARES

     Shares of the Portfolios are sold only (i) to fund deferred compensation
plans which are exempt from taxation under section 401(k) of the Internal
Revenue Code and (ii) to clients of financial advisers.

     Provided that shares of the Portfolios are available under an employer's
401(k) plan, shares may be purchased by following the procedures adopted by the
respective employer and approved by Fund management for making investments.
Shares are available through the service agent designated under the employer's
plan.  Investors who are considering an investment in the Portfolios should
contact their employer for details.  The Fund does not impose a minimum purchase
requirement, but investors should determine whether their employer's plan
imposes a minimum transaction requirement.

     Investors who are clients of financial advisers should contact their
financial adviser with respect to a proposed investment and then follow the
procedures adopted by the financial adviser for making purchases.  Shares that
are purchased or sold through omnibus accounts maintained by securities firms
may be subject to a service fee or commission for such transactions.  Clients of
financial advisers may also be subject to investment advisory fees under their
own arrangements with their financial advisers.

     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.

IN KIND PURCHASES

     If accepted by the Fund, shares of a Portfolio may be purchased in exchange
for securities which are eligible for acquisition by its corresponding Master
Fund or otherwise represented in the portfolios of the Master Fund as described
in this prospectus.  Shares may also be purchased in exchange for local
currencies in which such


                                          16

<PAGE>

securities of the International Value Series are denominated.  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, interests, subscription, or other rights
pertaining to such securities shall become the property of the Portfolio
whose shares are being acquired and must be delivered to the Fund by the
investor upon receipt from the issuer.  Investors who desire to purchase
shares of the DFA International Value Portfolio III 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 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
corresponding Master Fund may not exceed 5% of the net assets of the Master Fund
immediately after the transaction.  The Fund will accept such securities for
investment and not for resale.

     A gain or loss for federal income tax purposes will generally be realized
by investors who are subject to federal taxation upon the exchange depending
upon the cost of the securities or local currency exchanged.  Investors
interested in such exchanges should contact the Advisor.

                                 VALUATION OF SHARES

NET ASSET VALUE

     The net asset value per share of each Portfolio and Master Fund is
calculated as of the close of the NYSE by dividing the total market value of
its investments and other assets, less any liabilities, by the total
outstanding shares of the stock of the Portfolio or Master Fund.  The value
of each Portfolio's shares will fluctuate in relation to the investment
experience of the corresponding Master Fund.  Securities held by a Master
Fund 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.
 If there is no such reported sale, such securities are valued at the mean
between the most recent quoted bid and asked prices.  Price information on
listed securities is taken from the exchange where the security is primarily
traded.  Unlisted securities for which market quotations are readily
available are valued at the mean between the most recent quoted 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
Trustees of the Trust.

     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 the International Value Series are determined as of such times for the
purpose of computing the net asset value of the Master Fund.  If events which
materially affect the value of the foreign investments 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.  The net asset value per share of the International Value Series is
expressed in U.S. dollars by translating the net assets of the Master Fund using
the mean between the most recent quoted bid and asked prices for the dollar as
quoted by generally recognized reliable sources.

PUBLIC OFFERING PRICE

     Provided that a financial adviser or service agent designated under a
401(k) plan has received the investor's investment instructions in good order
and a Portfolio's custodian has received the investor's payment, shares of
the Portfolio selected will be priced at the net asset value calculated next
after receipt of the order by PFPC Inc., the transfer agent for the
Portfolios.  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.  The Fund reserves the right to redeem
shares owned by any purchaser whose order is canceled to recover any
resulting loss to the Fund and may


                                          17
<PAGE>

prohibit or restrict the manner in which such purchaser may place further
orders.

     Management believes that any dilutive effect of the cost of investing
the proceeds of the sale of the shares of the Portfolios is minimal and,
therefore, the shares of the Portfolios are currently sold at net asset
value, without imposition of a fee that would be used to reimburse a
Portfolio for such cost ("reimbursement fee").  Reimbursement fees may be
charged prospectively from time to time based upon the future experience of
the Portfolios and their corresponding Master Funds.  Any such charges will
be described in the prospectus.

                                  EXCHANGE OF SHARES

     An investor who is a client of a financial adviser may exchange shares
of one Portfolio for those of another Portfolio described in this prospectus
or a portfolio of DFA Investment Dimensions Group Inc., an open-end,
management investment company ("DFAIDG"), by first contacting its financial
adviser and completing the documentation required by the financial adviser.
Exchanges are accepted only into those portfolios of DFAIDG that are eligible
for the exchange privilege of DFAIDG.  In addition, exchanges are not
accepted into or from the DFA International Value Portfolio III.  Investors
should contact their financial advisor for a list of those portfolios of
DFAIDG that accept exchanges.

     An investor who has invested through an employer's 401(k) plan may exchange
shares of other Fund portfolios that are offered through the plan by completing
the necessary documentation as required by the service agent designated under
the employer's plan and the Advisor.  Please contact the service agent of your
plan for further information.

     The minimum amount for an exchange is $100,000.  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 or DFAIDG, the exchange
privilege may be terminated and any proposed exchange is subject to the
approval of the Advisor. Such approval will depend on:  (i) the size of the
proposed exchange; (ii) the prior number of exchanges by that shareholder;
(iii) the nature of the underlying securities and the cash position of the
Portfolio and of the portfolio of DFAIDG involved in the proposed exchange;
(iv) the transaction costs involved in processing the exchange; and (v) the
total number of redemptions by exchange already made out of the Portfolio.
Excessive use of the exchange privilege is defined as any pattern of
exchanges among portfolios by an investor that evidences market timing.

     With respect to shares held by clients of financial advisers, 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, plus any applicable reimbursement fee
on purchases by exchange.  "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 a
commercial bank, trust company or member 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 Fund may issue the
shares of the portfolio being acquired in compliance with the securities laws of
the investor's state of residence.

     With respect to shares held under a 401(k) plan, the redemption and
purchase prices of shares redeemed and purchased by exchange, respectively, are
the net asset values next determined after the plan's service agent has received
appropriate instructions in the form required by such service agent plus any
applicable reimbursement fee on purchases by exchange, and provided that such
service agent has provided proper documentation to the Advisor.

     There is no fee imposed on an exchange.  However, the Fund reserves the
right to impose an administrative fee in order to cover the costs incurred in
processing an exchange.  Any such fee will be disclosed in the prospectus.  An
exchange is treated as a redemption and a purchase.  Therefore, an investor
could realize a taxable gain or loss on the transaction.  The Fund reserves the
right to revise or terminate the exchange privilege, limit the amount of or
reject any exchange, or waive the minimum amount requirement as deemed
necessary, at any time.

                                 REDEMPTION OF SHARES

REDEMPTION PROCEDURES

     An investor who desires to redeem shares of a Portfolio must furnish a
redemption request to its financial adviser or to the service agent designated
under a 401(k) plan in the form required by such financial adviser or service
agent.  The Portfolio will redeem shares at the net asset value of such shares
next determined after receipt of a request for redemption in good order by PFPC
Inc.

     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.

REDEMPTION OF SMALL ACCOUNTS

     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 account 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 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.

REDEMPTION IN-KIND



     When in the best interest of a Portfolio, the Portfolio may make a
redemption payment, in whole or in part, by a distribution of portfolio
securities that the Portfolio receives from the Master Fund in lieu of cash
in accordance with Rule 18f-1 under the Investment Company Act of 1940.  The
International Value Series reserves the right to redeem its shares in the
currencies in which its investments are denominated.  Investors may incur
brokerage charges and other transaction costs selling such securities and
converting such currencies to dollars.  Also, the value of currencies may be
affected by currency exchange fluctuations.  The Tax-Managed Value Portfolios
and the Tax-Managed Value Series are authorized to make redemption payments
solely by a distribution of portfolio securities, or a combination of
securities and cash, when it is determined by the Advisor to be consistent
with the tax management strategies described in this prospectus and
applicable legal and regulatory requirements.



                                THE FEEDER PORTFOLIOS

     Other institutional investors, including other mutual funds, may invest
in each Master Fund.  The expenses of such other funds and, correspondingly,
their returns may differ from those of the Portfolios.  Please contact The
DFA Investment Trust Company at 1299 Ocean Avenue, 11th Floor Santa Monica,
CA 90401, (301) 395-8005 for information about the availability of investing
in a Master Fund other than through a Portfolio.

     The aggregate amount of expenses for a 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 Portfolios and the Master Funds are expected
to be less over time than such ratios would be if the Portfolios were to
invest directly in the underlying securities.  This arrangement enables
various institutional investors, including the Portfolios, to pool their
assets, which may be expected to result in economies by spreading certain
fixed costs over a larger asset base.  Each shareholder in a Master Fund,
including a Portfolio, will pay its proportionate share of the expenses of
that Master Fund.

     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

                                          19

<PAGE>

might be available at higher asset levels.  Investment in a Master Fund by
other institutional investors offers potential benefits to the Master Funds,
and through their investment in the Master Funds, the 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 Portfolio could have effective voting
control over the operation of the Master Fund.

     If the Board of Directors of the Fund determines that it is in the best
interest of a Portfolio, it may withdraw its investment in a Master Fund at
any time.  Upon any such withdrawal, the Board would consider what action the
Portfolio might take, including either seeking to invest its assets in
another registered investment company with the same investment objective as
the Portfolio, which might not be possible, or retaining an investment
advisor to manage the Portfolio's assets in accordance with its own
investment objective, possibly at increased cost.  Shareholders of a
Portfolio will receive written notice thirty days prior to the effective date
of any changes in the investment objective of its corresponding Master Fund.
A withdrawal by a 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 a 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 a Master Fund to a Portfolio
may constitute a taxable exchange for federal income tax purposes resulting
in gain or loss to such Portfolio.  Any net capital gains so realized will be
distributed to that Portfolio's shareholders as described in "DIVIDENDS,
CAPITAL GAINS DISTRIBUTIONS AND TAXES."

                                 FINANCIAL HIGHLIGHTS



     The Financial Highlights table is meant to help you understand each
Portfolio's financial performance for the period of that Portfolio's
operations, as indicated by the table.  No Financial Highlights are shown for
the Tax-Managed U.S. Marketwide Value Portfolio XI because it had not begun
operations as of May 31, 1999, so no information is available for it. The
total returns in the table represent the rate that you would have earned (or
lost) on an investment in the Portfolio, assuming reinvestment of all
dividends and distributions.  The information for the six-month period ended
May 31, 1999 has not been audited. The information for each of the fiscal
years has been audited by PricewaterhouseCoopers LLP, whose report, along
with the Portfolios' financial statements (except for the Tax Managed Value
Portfolios) are included in the Fund's annual report. Further information
about each Portfolio's performance (other than the Tax-Managed U.S.
Marketwide Value Portfolio XI) is contained in the Fund's annual and
semi-annual reports which are available upon request.

         RISK/RETURN SUMMARY


The Master Fund buys securities directly. The Portfolio invests in the Master
Fund's shares. The two have the same gross investment returns.


ABOUT THE PORTFOLIO

THE PORTFOLIO HAS A SPECIAL STRUCTURE: The Portfolio is a "Feeder Portfolio" --
a portfolio that does not buy individual securities directly. Instead, it
invests in a corresponding mutual fund, or "Master Fund", that in turn purchases
stocks, and other securities.

POSSIBLE COMPLICATIONS: The Master-Feeder structure is relatively new and more
complex. While this structure is designed to reduce costs, it may not do so. As
a result, the Portfolio might encounter operational or other complications.


MANAGEMENT

Dimensional Fund Advisors Inc. (the "Advisor") is the investment manager for the
Master Fund. (A Feeder Portfolio does not need an investment manager.)

EQUITY INVESTMENT APPROACH: The Advisor believes that equity investing should
involve a long-term view and a focus on asset class (e.g. S&P 500-Registered
Trademark- stocks) selection, not stock picking. It places priority on
limiting expenses, portfolio turnover and trading costs. The Portfolio buys a
Master Fund that is an index fund. Its only criteria for holding a stock is
whether the stock is in the S&P Index-Registered Trademark.

NO MARKET TIMING OR STOCK PICKING: Because the Master Fund is an index fund, the
Advisor does not take defensive positions in anticipation of negative investment
conditions, or try to pick potentially outperforming securities.

MARKET RISK: Even a long-term investment approach cannot guarantee a profit.
Economic, political and issuer specific events will cause the value of
securities and the Portfolio that owns them to rise or fall.

ABOUT THE S&P 500 INDEX: The Standard & Poor's 500 Composite Stock Price Index
is market capitalization weighted. Its performance is usually cyclical because
it reflects periods when stock prices generally rise or fall.


INVESTMENT OBJECTIVE, STRATEGY AND RISKS

- -    Investment Objective: Produce returns similar to those of S&P 500
     Index-REGISTERED TRADEMARK-.

- -    Investment Strategy: Buy shares of a Master Fund that invests in S&P 500
     Index-REGISTERED TRADEMARK- stocks in about the same proportions as they
     are found in the S&P 500 Index-REGISTERED TRADEMARK-.


OTHER RISKS

SECURITIES LENDING:

     The Master Fund purchased by the Portfolio may lend its portfolio
securities to generate additional income. If it does so, it will use various
strategies (for example, only making fully collateralized and bank guaranteed
loans) to reduce related risks.



YEAR 2000 ISSUE:

                                       3
<PAGE>

Unless modified, many computer programs will not properly process information
from the year 2000 on. The Advisor has taken steps designed to ensure that its
computers and those of Portfolio and Master Fund service providers (e.g.,
custodians) will operate properly. The Portfolio and Master Fund may be
negatively affected if the Advisor's efforts prove inadequate, and/or year 2000
problems hurt portfolio securities or economic conditions generally.

RISK AND RETURN BAR CHART AND TABLE

The Bar Chart and Table below illustrate the variability of the Master Fund's
returns and is meant to provide some indication of the risks of investing in the
Portfolio. Because the Portfolio is new, the returns shown in the Bar Chart and
Table are for the Master Fund and have been adjusted to reflect the anticipated
expenses of the Portfolio. Shown are changes in the Master Fund's performance
from year to year, and how annualized one year, five year and since inception
returns of the Master Fund compare with those of a broad measure of market
performance. Past performance is not an indication of future results.

           [A Bar Chart and Table reflecting the performance of
           the U.S. Large Company Series of the Trust, adjusted
           to reflect the projected expenses of the Portfolio,
           will be included in 485(b) filing prior to effective
           date.]

     Master Fund and an administration fee payable by the Portfolio.

**   "Other Expenses" is an annualized estimate based on anticipated fees and
     expenses payable by both the Master Fund and the Portfolio through the
     fiscal year ending November 30, 1999.

***  The Advisor and other service providers to the Portfolio and Master Fund
     have agreed to waive certain fees and to assume expenses of the Portfolio
     to the extent necessary to keep the cumulative annual expenses to not more
     than 0.10% of the average net assets of the Portfolio on an annualized
     basis. For purposes of this waiver and assumption, the annual expenses are
     those expenses incurred in any period consisting of thirty-six consecutive
     months. The Advisor and service providers retain the right in their sole
     discretion to change or eliminate such waiver and assumption of expenses in
     the future. Such change will be set forth in the prospectus.


                                     EXAMPLE


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

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

                                  1 YEAR          3 YEARS
                                  ------          -------
                                   $11              $35

The Example summarizes the aggregate estimated annual operating expenses before
any waivers of both the Portfolio and Master Fund. Because the Portfolio is new,
the Example is based on anticipated expenses for the current fiscal year and
does not extend over five-and ten-year periods.

MANAGEMENT AND ADMINISTRATIVE SERVICES

Dimensional Fund Advisors Inc. (the "Advisor" or "DFA") provides the Portfolio
with administrative services and serves as investment advisor to the Master
Fund. (See "MANAGEMENT OF THE PORTFOLIO.")

DIVIDEND POLICY

The Portfolio distributes dividends from its net investment income quarterly and
any realized net capital gains are distributed annually after November 30. (See
"DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES.")

PURCHASE, VALUATION AND REDEMPTION OF SHARES

The shares of the Portfolio are offered at net asset value, which is calculated
as of the close of the New York Stock Exchange ("NYSE") on each day that the
NYSE is open for business. The minimum initial purchase requirement for the
Portfolio's shares is $100,000,000. There is no minimum purchase requirement for
subsequent purchases. The value of the Portfolio's shares will fluctuate in
relation to the investment experience of the Master Fund. The redemption price
of a share of the Portfolio is equal to its net asset value. (See "PURCHASE OF
SHARES," "VALUATION OF SHARES" and "REDEMPTION OF SHARES.")


                        INVESTMENT OBJECTIVE AND POLICIES

U.S. Large Company Institutional Index Portfolio seeks, as its investment
objective, to approximate the investment performance of the S&P 500
Index-REGISTERED TRADEMARK-, in terms of its total investment return. The
Portfolio invests all of its assets in the U.S. Large Company Series of the
Trust (the "Master Fund"), which has the same investment objective and policies
as the Portfolio. The Master Fund intends to invest in all of the stocks that
comprise the S&P 500 Index-REGISTERED TRADEMARK- in approximately the same
proportions as they are represented in the Index. The amount of each stock
purchased for the Master Fund, therefore, will be based on the issuer's
respective market capitalization. The S&P 500 Index-REGISTERED TRADEMARK- is
comprised of a broad and diverse group of stocks most of which are traded on the
New York Stock Exchange ("NYSE"). Generally, these are the U.S. stocks with the
largest market capitalizations and, as a group, they represent approximately 70%
of the total market capitalization of all publicly traded U.S. stocks. Under
normal market conditions, at least 95% of the Master Fund's assets will be
invested in the stocks that comprise the S&P 500-REGISTERED TRADEMARK- Index.

The Master Fund 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 it invests in stock index futures contracts and
options thereon for other than bona fide hedging purposes, it will not purchase
such futures contracts or options if as a result more than 5% of its net assets
would then consist of initial margin deposits and premiums required to establish
such contracts or options.



                                       7
<PAGE>

Ordinarily, portfolio securities will not be sold except to reflect additions or
deletions of the stocks that comprise the S&P 500 Index-REGISTERED TRADEMARK-,
including mergers, reorganizations and similar transactions and, to the extent
necessary, to provide cash to pay redemptions of the Master Fund's shares.


                  STANDARD & POOR'S INFORMATION AND DISCLAIMERS

Neither the Portfolio nor Master Fund is sponsored, endorsed, sold or promoted
by Standard & Poor's Rating Group, a Division of The McGraw Hill Companies
("S&P"). S&P makes no representation or warranty, express or implied, to the
owners of the Portfolio or the Master Fund or any member of the public regarding
the advisability of investing in securities generally or in the Portfolio or the
Master Fund particularly or the ability of the S&P 500 Index-REGISTERED
TRADEMARK- to track general stock market performance. S&P's only relationship to
the Portfolio or the Master Fund is the licensing of certain trademarks and
trade names of S&P and of the S&P 500 Index-REGISTERED TRADEMARK- which is
determined, composed and calculated by S&P without regard to the Portfolio or
the Master Fund. S&P has no obligation to take the needs of the Portfolio, the
Master Fund or their respective owners into consideration in determining,
composing or calculating the S&P 500 Index-REGISTERED TRADEMARK-. S&P, is not
responsible for and has not participated in the determination of the prices and
amount of the Portfolio or the Master Fund or the issuance or sale of the
Portfolio or the Master Fund or in the determination or calculation of the
equation by which the Portfolio or the Master Fund is to be converted into cash.
S&P has no obligation or liability in connection with the administration,
marketing or trading of the Portfolio or the Master Fund.

     S&P DOES NOT GUARANTEE THE ACCURACY AND/OR THE COMPLETENESS OF THE S&P 500
INDEX-REGISTERED TRADEMARK- OR ANY DATA INCLUDED THEREIN AND S&P SHALL HAVE NO
LIABILITY FOR ANY ERRORS, OMISSIONS, OR INTERRUPTIONS THEREIN. S&P MAKES NO
WARRANTY, EXPRESS OR IMPLIED, AS TO RESULTS TO BE OBTAINED BY LICENSEE, OWNERS

OF THE FOREGOING, IN NO EVENT SHALL S&P HAVE ANY LIABILITY FOR ANY SPECIAL,
PUNITIVE, INDIRECT, OR CONSEQUENTIAL DAMAGES (INCLUDING LOST PROFITS), EVEN
IF NOTIFIED OF THE POSSIBILITY OF SUCH DAMAGES.

                          PORTFOLIO TRANSACTIONS

For both the Portfolio and the Master Fund, investments will generally be
made in eligible securities on a market capitalization weighted basis.
Securities will not be purchased or sold based on the prospects for the
economy, the securities markets or the individual issuers whose shares are
eligible for purchase. Securities which have depreciated in value since their
acquisition will not be sold solely because prospects for the issuer are not
considered attractive or due to an expected or realized decline in securities
prices in general. Securities will not be sold to realize short-term profits,
but when circumstances warrant, they may be sold without regard to the length
of time held.

Securities, including those eligible for purchase, may be
disposed of, however, at any time when, in the Advisor's judgement,
circumstances warrant their sale, including but not limited to tender offers,
mergers and similar transactions, or bids made for block purchases at
opportune prices. Generally, securities will be purchased with the
expectation that they will be held for longer than one year and will be held
until such time as they are no longer considered an appropriate holding in
light of the investment policy of the Portfolio.

                                SECURITIES LOANS

The Master Fund is authorized to lend securities to qualified brokers, dealers,
banks and other financial institutions for the purpose of earning additional
income. While the Master Fund may earn additional income from lending
securities, such activity is incidental to the Master Fund's investment
objective. The value of securities loaned may not exceed 33 1/3% of the value of
the Master Fund's total assets. In connection with such loans, the 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 Master Fund will
be able to terminate the loan at any time and will receive reasonable
compensation 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 Master Fund could experience delay in recovering the loaned
securities. Management believes that this risk can be controlled through careful
monitoring procedures. The Portfolio is also authorized to lend its portfolio
securities. However, as long as it holds only shares of the Master Fund, it will
not do so.


                            MANAGEMENT OF THE PORTFOLIO

The Advisor serves as investment advisor to the Master Fund. As such, it is
responsible for the management of its assets. The Advisor provides the Master
Fund with a trading department and selects brokers and dealers to effect
securities transactions.



                                       8
<PAGE>

Securities transactions are placed with a view to obtaining the best price and
execution of such transactions. The Advisor is authorized to pay a higher
commission to a broker, dealer or exchange member than another such organization
might charge if it determines, in good faith, that the commission paid is
reasonable in relation to the research or brokerage services provided by such
organization.

For the advisory fees the Portfolio will incur as a percentage of average net
assets, see "ANNUAL FUND OPERATING EXPENSES." The Advisor was organized in May,
1981, and is engaged in the business of providing investment management services
to institutional investors. Assets under management total approximately $28
billion.

The Portfolio and the Master Fund each bears all of its own costs and expenses,
including: services of its independent accountants, legal counsel, brokerage
commissions and transfer taxes in connection with the acquisition and
disposition of portfolio securities, taxes, insurance premiums, costs incidental
to meetings of its shareholders and directors or trustees, the cost of filing
its registration statements under federal securities laws and the costs of any
filings required under state securities laws, reports to shareholders, and
transfer and dividend disbursing agency, administrative services and custodian
fees. Expenses allocable to the Portfolio or the Master Fund are so allocated
and expenses which are not allocable to the Portfolio and the Master Fund are
borne by the Portfolio and the Master Fund on the basis of their relative net
assets.


                DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES

The Portfolio distributes substantially all net investment income quarterly and
any realized net capital gains are distributed annually after November 30.

Shareholders of the Portfolio will automatically receive all income dividends
and any capital gains distributions in additional shares of the Portfolio at net
asset value (as of the business date following the dividend record date), unless
upon written notice to PFPC Inc., the Portfolio's transfer agent, the
shareholder selects one of the following options:

          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.

Whether paid in cash or additional shares and regardless of the length of time
the Portfolio's shares have been owned by shareholders who are subject to
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.
Dividends from net investment income will generally qualify in part for the
corporate dividends received deduction. The portion of dividends so qualified
depends on the aggregate qualifying dividend income received by the Master Fund
from domestic (U.S.) sources.

For those investors subject to tax, if purchases of shares of the 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 federal
tax status of dividends and distributions paid by the Portfolio.

Dividends which are declared in November or December to shareholders of
record but which, for operational reasons, may not be paid to the shareholder
until the following January, will be treated for 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 the 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 of the
Portfolio for shares of another portfolio of the Fund. Any loss incurred on sale
or exchange of the Portfolio's shares, held for six



                                       9
<PAGE>

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.

Certain investments by the Master Fund may be subject to special rules which may
affect the amount, character and timing of the income to the Master Fund. Some
of these rules are referenced in the statement of additional information.

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

The Portfolio is required to withhold 31% of taxable dividends, capital gains
distributions, and redemptions paid to shareholders who have not complied with
IRS taxpayer identification regulations. You may avoid this withholding
requirement by certifying on the account registration form your proper Taxpayer
Identification Number and by certifying that you are not subject to backup
withholding.

The tax discussion set forth above is included for general information only.
Prospective investors should consult the statement of additional information.
Prospective investors should also consult their own tax advisers concerning the
federal, state, local or foreign tax consequences of an investment in the
Portfolio.


                                PURCHASE OF SHARES

Investors may purchase shares of the Portfolio by first contacting the Advisor
at (310) 395-8005 to notify the Advisor of the proposed investment. All
investments are subject to approval of the Advisor, and all investors must
complete and submit an Account Registration Form.

The minimum initial purchase requirement for the Portfolio's shares is
$100,000,000. Once the minimum purchase requirement is satisfied, further
investments in the Portfolio are not subject to any minimum purchase
requirement. The Fund reserves the right to reduce or waive the minimum
investment requirement, to reject any initial or additional investment and to
suspend the offering of shares of the Portfolio.

Investors having an account with a bank that is a member or a correspondent of a
member of the Federal Reserve System may purchase shares by first calling the
Advisor at (310) 395-8005 to notify the Advisor of the proposed investment, then
requesting the bank to transmit immediately available funds (Federal Funds) by
wire to the custodian, for the account of Dimensional Investment Group Inc.
(U.S. Large Company Institutional Index Portfolio). Additional investments also
may be made through the wire procedure by first notifying the Advisor. Investors
who wish to purchase shares by check should send their check to Dimensional
Investment Group Inc., c/o PFPC Inc., 400 Bellevue Parkway, Wilmington, Delaware
19809.

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

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.

IN-KIND PURCHASES

If accepted by the Fund, shares of the Portfolio may be purchased in exchange
for securities which are eligible for acquisition by the Master Fund or
otherwise represented in its portfolio as described in this prospectus.
Securities to be exchanged which are accepted by the Fund and shares of the
Portfolio 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 and must be delivered
to the Fund by the investor upon receipt from the issuer.



                                       10
<PAGE>

The Fund will not accept securities in exchange for shares of the Portfolio
unless: (1) such securities are, at the time of the exchange, eligible to be
included, or otherwise represented, in the 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 Master Fund under the
Securities Act of 1933 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 Master Fund may
not exceed 5% of the net assets of the Master Fund immediately after the
transaction. The Fund will accept such securities for investment and not for
resale.

A gain or loss for federal income tax purposes will generally be realized by
investors who are subject to federal taxation upon the exchange depending upon
the cost of the securities exchanged. Investors interested in such exchanges
should contact the Advisor.


                               VALUATION OF SHARES

NET ASSET VALUE

The net asset values per share of the Portfolio and the Master Fund are
calculated as of the close of the NYSE by dividing the total market value of
their respective investments and other assets, less any liabilities, by the
total outstanding shares of the stock of the Portfolio and the Master Fund,
respectively. The net asset values will not be calculated on days the NYSE is
closed, including national holidays. The value of the Portfolio's shares will
fluctuate in relation to the investment experience of the Master Fund.
Securities held by the Master Fund 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. If there is no such reported sale, the Master Fund values such
securities at the mean between the most recent quoted bid and asked prices.
Price information on listed securities is taken from the exchange where the
security is primarily traded. Unlisted securities for which market quotations
are readily available are valued at the mean between the most recent quoted 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 Trustees of the Trust.

PUBLIC OFFERING PRICE

Provided that the transfer agent has received the investor's Account
Registration form in good order and the custodian has received the investor's
payment, shares of the Portfolio will be priced at the net asset value
calculated next after receipt of the investor's funds by the custodian. "Good
order" with respect to the purchase of shares means that (1) a fully completed
and properly signed Account Registration form and any additional supporting
legal documentation required by the Advisor have been received in legible form
and (2) the Advisor has been notified of the purchase by telephone and, if the
Advisor so requests, also in writing, no later than the close of regular trading
on the NYSE (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.
The Fund reserves the right to redeem shares owned by any purchaser whose order
is canceled to recover any resulting loss to the Fund and may prohibit or
restrict the manner in which such purchaser may place further orders.

Management believes that any dilutive effect of the cost of investing the
proceeds of the sale of the shares of the Portfolio will be minimal and,
therefore, the shares of the Portfolio are currently sold at net asset value,
without imposition of a fee that would be used to reimburse the Portfolio for
such cost (a "reimbursement fee"). However, a reimbursement fee may be charged
prospectively from time to time based upon the future experience of the
Portfolio and the Master Fund. A reimbursement fee would be used to defray the
costs of investing in securities (such as brokerage commissions, taxes and other
transaction costs). Any such charge will be described in the prospectus.



                                       11
<PAGE>

                                EXCHANGE OF SHARES

Investors may exchange shares of the Portfolio for those of another portfolio in
the Fund or a portfolio of DFA Investment Dimensions Group Inc., an open-end,
management investment company ("DFAIDG"). Investors should first contact the
Advisor at (310) 395-8005 to notify the Advisor of the proposed exchange and
then complete an Exchange Form and mail it to:

                         Dimensional Investment Group Inc.
                         Attn:  Client Operations
                         1299 Ocean Avenue, 11th Floor
                         Santa Monica, CA  90401

The minimum amount for an exchange into a portfolio of DFAIDG is $100,000.
Exchanges are accepted only into those portfolios of DFAIDG that are eligible
for the exchange privilege of DFAIDG. Investors may contact the Advisor at the
above-listed phone number for a list of those portfolios of DFAIDG that accept
exchanges.

The exchange privilege is not intended to afford shareholders a way to speculate
on short-term movements in the markets. Accordingly, in order to prevent
excessive use of the exchange privilege that may potentially disrupt the
management of the Portfolio or otherwise adversely affect the Fund or DFAIDG,
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 Portfolio and of the portfolio of the
Fund or DFAIDG involved in the proposed exchange; (iv) the transaction costs
involved in processing the exchange; and (v) the total number of redemptions by
exchange already made out of the Portfolio. Excessive use of the exchange
privilege is defined as any pattern of exchanges among portfolios by an investor
that evidences market timing.

The redemption and purchase prices of shares redeemed and purchased by exchange,
respectively, are the net asset values next determined after the Advisor has
received an Exchange Form in good order, plus any applicable reimbursement fee
on purchases by exchange. "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 Fund or
DFAIDG may issue the shares of the portfolio being acquired in compliance with
the securities laws of the investor's state of residence.

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

REDEMPTION PROCEDURE

Investors who desire to redeem shares of the Portfolio must first contact the
Advisor at (310) 395-8005. The Portfolio will redeem shares at the net asset
value of such shares next determined after receipt of a written request for
redemption in good order by the Portfolio's transfer agent. "Good order"
means that the request to redeem shares must include all necessary
documentation, to

                                       12
<PAGE>

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: 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; 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.

Redeeming shareholders 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. 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 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 further investments. (See "PURCHASE OF SHARES.")

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.

REDEMPTION OF SMALL ACCOUNTS

The Fund reserves the right to redeem a shareholder's account if the value of
the shares in the account 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 Portfolio in order to bring the value of the shares
in the account to more than $500 and avoid such involuntary redemption. The
redemption price to be paid to a stockholder for shares redeemed by the Fund
under this right will be the aggregate net asset value of the shares in the
account at the close of business on the redemption date.

IN-KIND REDEMPTIONS

When in the best interests of the Portfolio, the Portfolio may make a redemption
payment, in whole or in part, by a distribution of portfolio securities that the
Portfolio receives from the Master Fund in lieu of cash. Such distributions will
be made in accordance with the federal securities laws and regulations governing
mutual funds. Investors may incur brokerage charges and other transaction costs
selling securities that were received in payment of redemptions.


                              THE FEEDER PORTFOLIO

Other institutional investors, including other mutual funds, may invest in the
Master Fund. The expenses of such other funds and, correspondingly, their
returns may differ from those of the Portfolio. Please contact the DFA
Investment Trust Company at 1299 Ocean Avenue, 11th Floor Santa Monica, CA
90401, (301) 395-8005 for information about the availability of investing in the
Master Fund other than through the Portfolio.

The aggregate amount of expenses for the Portfolio and the Master Fund may be
greater than it would be if the Portfolio were to invest directly in the
securities held by the Master Fund. However, the total expense ratios for the
Portfolio and the Master Fund are expected to be less over time than such ratios
would be if the Portfolio were to invest directly in the underlying securities.
This arrangement enables various institutional investors, including the
Portfolio, to pool their assets, which may be expected to result in economies by
spreading certain fixed costs over a larger asset base. Each shareholder in the
Master Fund, including the Portfolio, will pay its proportionate share of the
expenses of the Master Fund.


                                       13
<PAGE>

The shares of the Master Fund 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 the Master Fund by other
institutional investors offers potential benefits to the Master Fund and,
through its investment in the Master Fund, the Feeder Portfolio 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 Fund. Also, if an
institutional investor were to redeem its interest in the Master Fund, the
remaining investors in the 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 the
Master Fund than the Portfolio could have effective voting control over the
operation of the Master Fund.

If the Board of Directors of the Fund determines that it is in the best interest
of the Portfolio, it may withdraw its investment in the Master Fund at any time.
Upon any such withdrawal, the Board would consider what action the Portfolio
might take, including either seeking to invest its assets in another registered
investment company with the same investment objective as the Portfolio, which
might not be possible, or retaining an investment advisor to manage the
Portfolio's assets in accordance with its own investment objective, possibly at
increased cost. Shareholders of the Portfolio will receive written notice thirty
days prior to the effective date of any changes in the investment objective of
the Master Fund. A withdrawal by the Portfolio of its investment in the 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 a Portfolio could result in a less diversified portfolio of
investments and could affect adversely the liquidity of the Portfolio. Moreover,
a distribution in kind by the Master Fund to the Portfolio may constitute a
taxable exchange for federal income tax purposes resulting in gain or loss to
the Portfolio. Any net capital gains so realized will be distributed to the
Portfolio's shareholders as described in "DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS
AND TAXES."

                        PORTFOLIO CHARACTERISTICS AND POLICIES

     The following information supplements the information set forth in the
prospectus.  Unless otherwise indicated, it applies to the DFA International
Value Series (the "International Value Series"), the DFA U.S. Large Cap Value
Series (the "Large Cap Value Series"), the Tax-Managed U.S. Mareketwide Value
Series and the Tax-Managed U.S. Marketwide Value Series X (collectively, the
"Master Funds") of The DFA Investment Trust Company (the "Trust") and the
Portfolios through their investment in the Master Funds.  Capitalized terms
not otherwise defined in this SAI have the meaning assigned to them in the
prospectus. The Tax-Managed U.S. Marketwide Value Series and the Tax-Managed
U.S. Marketwide Value Series X are collectively called the "Tax-Managed Value
Series."

     Dimensional Fund Advisors Inc. (the "Advisor") serves as investment advisor
to each Master Fund and provides administrative services to the Portfolios.

     Each of the Portfolios and the Master Funds are diversified under the
federal securities laws and regulations.

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


                                BROKERAGE COMMISSIONS



     The following table depicts brokerage commissions paid by the designated
Master Funds.

</TABLE>


     The substantial increases or decreases in the amount of brokerage
commissions paid by the International Value Series from year to year resulted
from increases or decreases in the amount of securities that were bought and
sold by the International Value Series.  The Tax-Managed Value Series had not
begun operations by November 30, 1998.

     Portfolio transactions of each Master Fund will be placed with a view to
receiving the best price and execution.  In addition, the Advisor will seek to
acquire and dispose of securities in a manner 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.  Brokers will be
selected with these goals in view.  The Advisor monitors the performance of
brokers which effect transactions for the Master Funds 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 Master
Funds to their brokers to ascertain that they are competitive with those charged
by other brokers for similar services.

     Transactions also may be placed with brokers who provide the Advisor with
investment research, such as reports concerning individual issuers, industries
and general economic and financial trends and other research services.  The
Investment Management Agreement of each Master Fund permits the Advisor
knowingly to pay commissions on these transactions which are greater than
another broker, dealer or exchange member might charge if the Advisor, in good
faith, determines that the commissions paid are reasonable in relation to the
research or


                                          2
<PAGE>

brokerage services provided by the broker or dealer when viewed in terms of
either a particular transaction or the Advisor's overall responsibilities to
assets under its management.  Research services furnished by brokers through
whom securities transactions are effected may be used by the Advisor in
servicing all of its accounts and not all such services may be used by the
Advisor with respect to the Master Funds.


     During fiscal year 1998, the following Master Funds paid commissions for
securities transactions to brokers which provided market price monitoring
services, market studies and research services to the Master Funds as follows:


<TABLE>
<CAPTION>

International Value Series                  $  2,427,926             $15,569
Large Cap Value Series                      $ 71,611,201              65,046
                                            ------------             -------
</TABLE>


     The over-the-counter market companies eligible for purchase by the Large
Cap Value Series and each Tax-Managed Value Series are thinly traded
securities. Therefore, the Advisor believes it needs maximum flexibility to
effect over-the-counter 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 dealers 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
sometimes to trade larger blocks than would be possible by going through a
single market maker.


     The Advisor places buy and sell orders on Instinet when the Advisor
determines that the securities may not be available from other sources at a more
favorable price.  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, a Master Fund, 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
Master Fund can effect transactions at the best available prices.

     The Portfolios will not incur any brokerage or other costs in connection
with its purchase or redemption of shares of its Master Fund, except if a
Portfolio receives securities or currencies from the Master Fund to satisfy the
Portfolio's redemption request.


                                INVESTMENT LIMITATIONS

     Each of the Portfolios has adopted certain limitations which may not be
changed with respect to any Portfolio without the approval of the holders 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 effected 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 investment limitations of each Master
Fund are the same as those of the corresponding Portfolio.

     The Portfolios will not:

     (1)  invest in commodities or real estate, including limited partnership
interests therein, 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 may purchase or sell financial futures contracts and options thereon;

     (2)  make loans of cash, except through the acquisition of repurchase
agreements and obligations customarily purchased by institutional investors;


                                          3
<PAGE>

     (3)  as to 75% of the total assets of a Portfolio, invest in the securities
of any issuer (except obligations of the U.S. Government and its agencies and
instrumentalities) if, as a result of more than 5% of the Portfolio's total
assets, at market, would be invested in the securities of such issuer;


     (4)  purchase or retain securities of an issuer, if those officers and
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
Tax-Managed Value Portfolios are not subject to this limitation;


     (5)  borrow, except from banks as a temporary measure for extraordinary or
emergency purposes and, then, in no event, in excess of 33% of its net assets,
or pledge more than 33% of such assets to secure such loans;


     (6)  pledge, mortgage, or hypothecate any of its assets to an extent
greater than 10% of its total assets at fair market value, except as
described in (5) above; provided that the Tax-Managed Value Portfolios are
not subject to this limitation;


     (7)  invest more than 15% of the value of the Portfolio's total assets
in illiquid securities, which include certain restricted securities,
repurchase agreements with maturities of greater than seven days, and other
illiquid investments; provided that the Tax-Managed Value Portfolios are not
subject to this limitation;


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


     (9)  invest for the purpose of exercising control over management of any
company; provided that the Tax-Managed Value Portfolios are not subject to
this limitation;


     (10) invest its assets in securities of any investment company, except
in connection with a merger, acquisition of assets, consolidation or
reorganization; provided that each Tax-Managed Value Portfolio may invest its
assets in securities of investment companies and units of such companies such
as, but not limited to, S&P Depository Receipts;


     (11) invest more than 5% of its total assets in securities of companies
which have (with predecessors) a record of less than three years' continuous
operation; provided that the Tax-Managed Value Portfolios are not subject to
this limitation;


     (12) acquire any securities of companies within one industry if, as a
result of such acquisition, more than 25% of the value of the Portfolio's total
assets would be invested in securities of companies within such industry;


     (13) write or acquire options (except as described in (1) above) or
interests in oil, gas or other mineral exploration, leases or development
programs; provided that the Tax-Managed Value Portfolios may write or acquire
options;


     (14) purchase warrants, except that the Portfolios may acquire warrants
as a result of corporate actions involving their holdings of equity
securities; provided that the Tax-Managed Value Portfolios are not subject to
this limitation;


     (15) purchase securities on margin or sell short; provided that the
Tax-Managed Value Portfolios 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 U.S.
Large Cap Value Portfolio III; and (b) provided that the Tax-Managed Value
Portfolios 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.


                                          4
<PAGE>

     The investment limitations described in (3), (4), (7), (9), (10), (11),
(12) and (16) above do not prohibit each 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.

     The investment limitations described in (1) and (15) above do not prohibit
each Portfolio from making margin deposits in connection with the purchase or
sale of financial futures contracts and options thereon to the extent permitted
under applicable regulations.


     Although (2) above prohibits cash loans, the Portfolios are authorized to
lend portfolio securities.  Inasmuch as the Portfolios will only hold shares of
a corresponding Master Fund, the Portfolios do not intend to lend those shares.


     Although not a fundamental policy subject to shareholder approval, each
Tax-Managed Value Portfolio, indirectly through its investment in its
corresponding Master Fund, does not intend to invest more than 15% of its net
assets in illiquid securities.

     Pursuant to Rule 144A under the Securities Act of 1933 (the "1933 Act"),
the Master Funds 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 15% limitation on holdings of illiquid securities
stated in (7) above.  While maintaining oversight, the Board of Trustees of the
Trust 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 Trustees and the Advisor will continue to monitor the liquidity of Rule
144A securities.

     The International Value Series 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 the
Master Funds have retained authority to buy and sell financial futures contracts
and options thereon, they have no present intention to do so.

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

     Unless otherwise indicated, all limitations applicable to the Portfolios'
and Master Funds' investments apply only at the time that a transaction is
undertaken.  Any subsequent change in 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 Funds' 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 close out the
investment without undue market or tax consequences.  With respect to illiquid
securities, if a fluctuation in value causes a Portfolio or Master Fund to go
above its limitations on investments in illiquid securities, the Board of
Directors will consider what action, if any, should be taken to reduce the
percentage to the applicable limitation.


                                  FUTURES CONTRACTS

     The Master Funds each may enter into futures contracts and options on
futures contracts for the purpose of remaining fully invested and to maintain
liquidity to pay redemptions.  Futures contracts provide for the future sale by
one party and purchase by another party of a specified amount of defined
securities at a specified future time and at a specified price.  Futures
contracts which are standardized as to maturity date and underlying financial
instrument are traded on national futures exchanges.  A Master Fund will be
required to make a margin deposit in cash or government securities with a broker
or custodian to initiate and maintain positions in futures contracts.  Minimal
initial margin requirements are established by the futures exchange and brokers
may establish margin requirements which are higher than the exchange
requirements.  After a futures contract position is opened, the


                                          5
<PAGE>

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 a Master Fund.  Variation margin
payments are made to and from the futures broker for as long as the contract
remains open.  The Master Funds expect to earn income on their margin deposits.
To the extent that a Master Fund invests in futures contracts and options
thereon for other than bona fide hedging purposes, no Master Fund 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 net assets, after taking into account unrealized profits
and unrealized losses on such contracts it has entered into; provided, however,
that, in the case of an option that is in-the-money at the time of purchase, the
in-the-money amount may be excluded in calculating the 5%.  Pursuant to
published positions of the Securities and Exchange Commission (the "SEC"), the
Master Funds may be required to maintain segregated accounts consisting of
liquid assets, such as cash, or liquid securities (or, as permitted under
applicable regulation, enter into offsetting positions) in connection with their
futures contract transactions in order to cover their 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, a Master Fund would continue to be
required to make variation margin deposits.  In such circumstances, if a Master
Fund has insufficient cash, it might have to sell portfolio securities to meet
daily margin requirements at a time when it might be disadvantageous to do so.
Management intends to minimize the possibility that it will be unable to close
out a futures contract by only entering into futures which are traded on
national futures exchanges and for which there appears to be a liquid secondary
market.


                              CASH MANAGEMENT PRACTICES

     The Portfolios and Master Funds engage in cash management practices in
order to earn income on uncommitted cash balances.  Generally, cash is
uncommitted pending investment in other obligations, payment of redemptions or
in other circumstances where the Advisor believes liquidity is necessary or
desirable.  All the Portfolios and Master Funds may invest cash in short-term
repurchase agreements.  In addition, the following cash investments are
permissible:

                                CONVERTIBLE DEBENTURES

     The International Value Series may invest up to 5% of its assets in
convertible debentures issued by non-U.S. companies located in countries where
it is permitted to invest.  Convertible debentures include corporate bonds and
notes that may be converted into or exchanged for common stock.  These
securities are generally convertible either at a stated price or a stated rate
(that is, for a specific number of shares of common stock or other security).
As with other fixed income securities, the price of a convertible debenture to
some extent varies inversely with interest rates.  While providing a
fixed-income stream (generally higher in yield than the income derived from a
common stock but lower than that afforded by a non-convertible 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, the International Value Series may be required to pay for a convertible
debenture an amount in excess of the value of the underlying common stock.
Common stock acquired by the International Value Series upon conversion of a
convertible debenture will generally be held for as long as the Advisor
anticipates such stock will provide the International Value Series with
opportunities which are consistent with its investment objective and policies.

*    The term Fund Complex refers to all registered investment companies for
     which the Advisor performs advisory or administrative services and for
     which the individuals listed above serve as directors.

                                 SERVICES TO THE FUND

ADMINISTRATIVE SERVICES

     The Fund has entered into an administration agreement with the Advisor
on behalf of each Portfolio.  Pursuant to the administration agreement, the
Advisor will perform various services, including:  supervision of the
services provided by the Portfolio's custodian and transfer and dividend
disbursing agent and others who provide services to the Fund for the benefit
of the Portfolio; assisting the Fund to comply with the provisions of
federal, state, local and foreign securities, tax and other laws applicable
to the Portfolio; providing shareholders of record with information about the
Portfolio and their investments as they or the Fund may request; assisting
the Fund to conduct meetings of shareholders; furnishing information as the
Board of Directors may require regarding the Master Funds; and any other
administrative services for the benefit of the Portfolio as the Board of
Directors may reasonably request. The Advisor also provides the Fund with
office space and personnel.  For its administrative services, the Portfolios
each pay the Advisor a monthly fee equal to one-twelfth of 0.01% of their
respective average net assets, except for the Tax-Managed Value Portfolios,
which pay no fee.


     PFPC Inc. ("PFPC"), 400 Bellevue Parkway, Wilmington, DE  19809, serves as
the accounting services, dividend disbursing and transfer agent for the
Portfolios and the Master Funds.  The services provided by PFPC are subject to
supervision by the executive officers and the Board of Directors of the Fund and
include day-to-day keeping and maintenance of certain records, calculation of
the net asset value of the shares, preparation of reports, liaison with the
custodians, and transfer and dividend disbursing agency services.  PFPC's
charges for its services to each Portfolio are based on the number of feeder
portfolios investing in the corresponding Master Fund and whether the Master
Fund is organized to be taxed as a corporation or partnership.  PFPC's charges
are allocated among the

                                          9
<PAGE>

feeder portfolios investing in the Master Fund based on their relative net
assets.  PFPC charges a group of feeder portfolios investing in a Master Fund
which is taxed as a corporation $1,000 per month multiplied by the number of
feeder portfolios.  This applies to the DFA International Value Portfolio III
and the U.S. Large Cap Value Portfolio III.  Each Tax-Managed Value
Portfolio's corresponding Master Fund is taxed as a partnership, and each
Tax-Managed Value Portfolio will pay PFPC a monthly fee of $2,600.


CUSTODIANS

     PFPC Trust Company, 400 Bellevue Parkway, Wilmington, DE  19809, serves as
the custodian for the Portfolios and Master Funds.  Citibank, N.A., 111 Wall
Street, New York, New York 10005, is the global custodian for the International
Value Series.  The custodians maintain a separate account or accounts for the
Portfolios and the Master Funds; receive, hold and release portfolio securities
on account of the Portfolios and the Master Funds; make receipts and
disbursements of money on behalf of the Portfolios and the Master Funds; and
collect and receive income and other payments and distributions on account of
the Portfolios' and the Master Funds' portfolio securities.

DISTRIBUTOR

     The Fund acts as distributor of each series of its own shares of stock.
The Fund 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.

LEGAL COUNSEL

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


                                    ADVISORY FEES

David G. Booth and Rex A. Sinquefield, as directors and officers of the
Advisor and shareholders of the Advisor's outstanding stock, may be deemed
controlling persons of the Advisor.  For the services it provides as
investment advisor to each Master Fund, the Advisor is paid a monthly fee
calculated as a percentage of average net assets of the Master Fund.  For the
fiscal years ended November 30, 1998, 1997 and 1996, the Master Funds paid
advisory fees as set forth in the following table (the Tax-Managed Value
Series had not begun operating as of November 30, 1998):

                                 GENERAL INFORMATION

     The Fund was incorporated under Maryland law on March 19, 1990.  The Fund
was known as DFA U.S. Large Cap Inc. from February, 1992, until it amended its
Articles of Incorporation in April 1993, to change to its present name.  Prior
to a February 1992, amendment to the Articles of Incorporation, it was known as
DFA U.S. Large Cap Portfolio Inc.  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.


                                          10
<PAGE>

                                  SHAREHOLDER RIGHTS

     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 Portfolio.  Ordinarily, the Fund does not intend
to hold annual meetings of shareholders, except as required by the 1940 Act or
other applicable law.  The Fund's by-laws 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.

     Whenever a 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 Portfolio's shareholders with respect to the proposal.
The Directors of the Fund will then vote the Portfolio's shares in the Master
Fund in accordance with the voting instructions received from the Portfolio's
shareholders.  The Directors of the Fund will vote shares of the Portfolio for
which they receive no voting instructions in accordance with their best
judgment.

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


                           PRINCIPAL HOLDERS OF SECURITIES

     As of August 31, 1999, the following person(s) beneficially owned 5% or
more of the outstanding stock of each Portfolio (prior to the date of this
SAI, the Tax-Managed U.S. Marketwide Value Portfolio XI had no operations

     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 it is open on
Good Friday and closed on Columbus Day and Veterans' Day.  Orders for
redemptions and purchases will not be processed if the Fund is closed.

     The Fund reserves the right, in its sole discretion, to suspend the
offering of shares of any or all Portfolios or reject purchase orders when, in
the judgment 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.


                                 REDEMPTION OF SHARES

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

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


                              TAXATION OF THE PORTFOLIOS

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

DISTRIBUTION OF NET INCOME

     Each Portfolio receives income generally in the form of dividends and
interest on its investments.  This income, less expenses incurred in the
operation of a Portfolio, constitutes its net investment income from which
dividends may be paid to its shareholders.  Any distributions by a Portfolio
from such income will be taxable to a shareholder as ordinary income, whether
they are received in cash or in additional shares.

DISTRIBUTIONS OF CAPITAL GAINS

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

                                          12
<PAGE>

     Each Portfolio intends to qualify each year as a regulated investment
company by satisfying certain distribution and asset diversification
requirements under the Internal Revenue Code (the "Code").  As a regulated
investment company, the Portfolios generally pay no federal income tax on the
income and gains it distributes to its shareholders.  The Board reserves the
right not to maintain the qualification of a Portfolio as a regulated investment
company, if it determines such course of action to be beneficial to
shareholders.  In such case, a Portfolio will be subject to federal, and
possibly state, corporate taxes on its taxable income and gains, and
distributions to shareholders will be taxed as ordinary dividend income to the
extent of a Portfolio's available earnings and profits.

EXCISE TAX DISTRIBUTION REQUIREMENT

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

EFFECT OF FOREIGN INVESTMENTS ON DISTRIBUTIONS

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

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

DIVIDENDS RECEIVED DEDUCTION

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

REDEMPTION OF PORTFOLIO SHARES

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

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


                                          13

U.S. GOVERNMENT OBLIGATIONS

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

COMPLEX SECURITIES

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

OTHER SPECIAL RULES APPLICABLE TO FEEDER PORTFOLIOS WHICH INVEST IN MASTER FUNDS

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



INFORMATION ON THE TAX CHARACTER OF DISTRIBUTIONS

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


                           CALCULATION OF PERFORMANCE DATA

     The Portfolios and the Master Funds may disseminate reports of their
investment performance from time to time.  Investment performance is
calculated on a total return basis; that is by including all net investment
income and any realized and unrealized net capital gains or losses during the
period for which investment performance is reported.  If dividends or capital
gains distributions have been paid during the relevant period, the
calculation of investment performance will include such dividends and capital
gains distributions as though reinvested in shares of the Portfolio or Master
Fund.  Standard quotations of total return are computed in accordance with
SEC Guidelines and are presented whenever any non-standard quotations are
disseminated. Non-standardized total return quotations may differ from the
SEC Guideline computations by covering different time periods.  In all cases,
disclosures are made when performance quotations differ from the SEC
Guidelines.  Performance data is based on historical earnings and is not
intended to indicate future performance.  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 and semi-annual reports to shareholders of the Portfolios
for the fiscal year ended November 30, 1998 and the period ended May 31,
1999, contain additional performance information.  A copy of the annual and
semi-annual reports are available upon request and without charge.

                                          14

     With respect to the DFA International Value Portfolio III, 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 (and its corresponding Master Fund) as
well as the performance of the local currency or currencies of the Portfolio.

     Quotations of the annualized percentage total returns for each Portfolio
for the one-, five-, and ten-year periods ended November 30, 1998 (as
applicable) are set forth in the prospectus.  Such quotations use the
standardized method of calculation required by the SEC.

     For purposes of calculating the performance of the Portfolios, the
performance of the corresponding Master Fund will be utilized for the period
prior to when each Portfolio commenced operations and, if applicable, restated
to reflect a Portfolio's fees and expenses.  As the following formula indicates,
each Portfolio and Master Fund determines its average annual total return 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 calculation also assumes the account
was completely redeemed at the end of each period and the deduction of all
applicable charges and fees.  According to the SEC's 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 required
by the SEC, the Portfolios and the Master Funds may disseminate other
performance data and may advertise total return 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 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.

                     PORTFOLIO CHARACTERISTICS AND POLICIES

          The following information supplements the information set forth in the
prospectus. Unless otherwise indicated, it applies to the U.S. Large Company
Series (the "Master Fund") of The DFA Investment Trust Company (the "Trust") and
the Portfolio through its investment in the Master Fund. Capitalized terms not
otherwise defined in this SAI have the meaning assigned to them in the
prospectus.

          Dimensional Fund Advisors Inc. (the "Advisor") serves as investment
advisor to the Master Fund and provides administrative services to the
Portfolio.

          The Portfolio and the Master Fund are diversified under the federal
securities laws and regulations.

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

                             BROKERAGE COMMISSIONS

          During the fiscal years ended November 30, 1998, 1997 and 1996, the
Master Fund paid total brokerage commissions of $15,841, $40,689 and $72,262,
respectively. The substantial increases or decreases in the amount of brokerage
commissions paid by the Master Fund from year to year resulted from increases or
decreases in the amount of securities that were bought and sold by the Master
Fund.

          Portfolio transactions of the Master Fund will be placed with a view
to receiving the best price and execution. In addition, the Advisor will seek to
acquire and dispose of securities in a manner 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. Brokers will be
selected with these goals in view. The Advisor monitors the performance of
brokers which effect transactions for the Master Fund to determine the effect
that their trading has on the market prices of the securities in which it
invests. The Advisor also checks the rate of commission being paid by the Master
Fund to its brokers to ascertain that they are competitive with those charged by
other brokers for similar services.

          Transactions also may be placed with brokers who provide the Advisor
with investment research, such as reports concerning individual issuers,
industries and general economic and financial trends and other research
services. The Investment Management Agreement of the Master Fund permits the
Advisor knowingly to pay commissions on these transactions which are greater
than another broker, dealer or exchange member might charge if the Advisor, in
good faith, determines that the commissions paid are reasonable in relation to
the research or brokerage services provided by the broker or dealer when viewed
in terms of either a particular transaction or the Advisor's overall
responsibilities to the assets under management. During fiscal year 1998, the
Master Fund did not pay any commissions for securities transactions to brokers
which provided market price monitoring services, market studies and research
services to the Master 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 Master Fund.



                                       2
<PAGE>

          The over-the-counter market companies eligible for purchase by the
Master Fund are thinly traded securities. Therefore, the Advisor believes it
needs maximum flexibility to effect over-the-counter 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 dealers 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
sometimes to trade larger blocks than would be possible by going through a
single market maker.

          The Advisor places buy and sell orders on Instinet when the Advisor
determines that the securities may not be available from other sources at a more
favorable price. 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 Master Fund, 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 Master Fund can effect
transactions at the best available prices.

          The Portfolio will not incur any brokerage or other costs in
connection with its purchase or redemption of shares of the Master Fund, except
if the Portfolio receives securities from the Master Fund to satisfy the
Portfolio's redemption request.

                             INVESTMENT LIMITATIONS

          The Portfolio and Master Fund have adopted certain limitations
which may not be changed without the approval of the holders 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
or Master Fund (to be effected by the proposed change) present at a meeting,
if the holders of more than 50% of the outstanding voting securities of the
Portfolio or Master Fund are present or represented by proxy, or (2) more
than 50% of the outstanding voting securities of the Portfolio or Master Fund.

         The Portfolio and Master Fund will not:

(1)      invest in commodities or real estate, including limited partnership
         interests therein, although it may purchase and sell securities of
         companies which deal in real estate and securities which are secured by
         interests in real estate, and may purchase or sell financial futures
         contracts and options thereon;

(2)      make loans of cash, except through the acquisition of repurchase
         agreements and obligations customarily purchased by institutional
         investors;

(3)      as to 75% of its total assets, invest in the securities of any issuer
         (except obligations of the U.S. Government and its agencies and
         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;

(4)      borrow, except from banks and as a temporary measure for extraordinary
         or emergency purposes and then, in no event, in excess of 33% of its
         net assets, or pledge more than 33% of such assets to secure such
         loans;

                                       3
<PAGE>

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

(6)      acquire any securities of companies within one industry if, as a
         result of such acquisition, more than 25% of the value of the
         Portfolio's total assets would be invested in securities of companies
         within such industry;

(7)      purchase securities on margin or sell short; or

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

In addition to the above investment limitations, the Master Fund has adopted
the following investment limitations, which may not be changed without
shareholder approval, as discussed above, The Master Fund will not:

(9)      purchase or retain securities of an issuer, if those officers and
         directors of the Trust or the Advisor owning more than 1/2 of 1% of
         such securities together own more than 5% of such securities;

(10)     pledge, mortgage, or hypothecate any of its assets to an extent
         greater than 10% of its total assets at fair market value, except as
         described in (9) above;

(11)     invest more than 15% of the value of the Master Fund's total assets in
         illiquid securities, which include certain restricted securities,
         repurchase agreements with maturities of greater than seven days, and
         other illiquid investments;

(12)     invest for the purpose of exercising control over management of any
         company;

(13)     invest its assets in securities of any investment company, except in
         connection with a merger, acquisition of assets, consolidation or
         reorganization;

(14)     invest more than 5% of its total assets in securities of companies
         which have (with predecessors) a record of less than three years'
         continuous operation;

(15)     write or acquire options or interests in oil, gas or other mineral
         exploration, leases or development programs;

(16)     purchase warrants, except that the Master Fund may acquire warrants
         as a result of corporate actions involving its holdings of equity
         securities; or

(17)     acquire more than 10% of the voting securities of any issuer.

          The investment limitations described in (3) and (6) above do not
prohibit the Portfolio from investing all or substantially all of its assets
in the shares of another registered open-end investment company, such as the
Master Fund.

          The investment limitations described in (1) and (7) above do not
prohibit the Portfolio or Master Fund from making margin deposits in
connection with the purchase or sale of financial futures contracts and
options thereon to the extent permitted under applicable regulations.

          Although (2) above prohibits cash loans, the Portfolio and Master
Fund are authorized to lend portfolio securities. Inasmuch as the Portfolio
will only hold shares of the Master Fund, the Portfolio does not intend to
lend those shares.

          Pursuant to Rule 144A under the Securities Act of 1933 (the "1933
Act"), the Master Fund 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 Master Fund's limitations on holdings
of illiquid securities stated in (11) above. While maintaining oversight, the
Board of Trustees of the Trust 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 Trustees and the Advisor will
continue to monitor the liquidity of Rule 144A securities.

          Subject to future regulatory guidance, for purposes of those
investment limitations identified above that are based on total assets, "total
assets" refers to the assets that the Portfolio or Master Fund owns, and does
not include assets which the Portfolio or Master Fund does not own but over
which it has effective control. For example, when applying a percentage
investment limitation that is based on total assets, the Portfolio or Master



                                       4
<PAGE>

Fund will exclude from its total assets those assets which represent collateral
received by the Portfolio or Master Fund for its securities lending
transactions.

          Unless otherwise indicated, all limitations applicable to the
Portfolio's and Master Fund's investments apply only at the time that a
transaction is undertaken. Any subsequent change in the percentage of the
Portfolio's or Master Fund's assets invested in certain securities or other
instruments resulting from market fluctuations or other changes in the
Portfolio's or Master Fund's total assets will not require the Portfolio or
Master Fund to dispose of an investment until the Advisor determines that it is
practicable to sell or close out the investment without undue market or tax
consequences.


                                FUTURES CONTRACTS

          The Master Fund may enter into futures contracts and options on
futures contracts for the purpose of remaining fully invested and to maintain
liquidity to pay redemptions. Futures contracts provide for the future sale by
one party and purchase by another party of a specified amount of defined
securities at a specified future time and at a specified price. Futures
contracts which are standardized as to maturity date and underlying financial
instrument are traded on national futures exchanges. The Master Fund will be
required to make a margin deposit in cash or government securities with a broker
or custodian to initiate and maintain positions in futures contracts. Minimal
initial margin requirements are established by the futures exchange, and brokers
may establish margin requirements which are higher than the exchange
requirements. After a futures contract position is opened, the value of the
contract is marked to market daily. If the futures contract price changes, to
the extent that the margin on deposit does not satisfy margin requirements,
payment of additional "variation" margin will be required. Conversely, reduction
in the contract value may reduce the required margin resulting in a repayment of
excess margin to the Master Fund. Variation margin payments are made to and from
the futures broker for as long as the contract remains open. The Master Fund
expects to earn income on its margin deposits. To the extent that the Master
Fund invests in futures contracts and options thereon for other than bona fide
hedging purposes, the Master Fund will not 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 net
assets, after taking into account unrealized profits and unrealized losses on
such contracts it has entered into; provided, however, that, in the case of an
option that is in-the-money at the time of purchase, the in-the-money amount may
be excluded in calculating the 5%. Pursuant to published positions of the
Securities and Exchange Commission (the "SEC"), the Portfolio or Master Fund may
be required to maintain segregated accounts consisting of liquid assets such as
cash, U.S. government securities, or other high grade debt obligations (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 Master Fund would continue to
be required to make variation margin deposits. In such circumstances, if the
Master Fund has insufficient cash, it might have to sell portfolio securities to
meet daily margin requirements at a time when it might be disadvantageous to do
so. Management intends to minimize the possibility that it will be unable to
close out a futures contract by only entering into futures which are traded on
national futures exchanges and for which there appears to be a liquid secondary
market.


                            CASH MANAGEMENT PRACTICES

          The Portfolio and Master Fund engage in cash management practices in
order to earn income on uncommitted cash balances. Generally, cash is
uncommitted pending investment in other obligations, payment of redemptions or
in other circumstances where the Advisor believes liquidity is necessary or
desirable. The Portfolio and Master Fund may invest cash in short-term
repurchase agreements. In addition, the Master Fund may invest a



                                       5
<PAGE>

portion of its assets, generally not more than 5% of its net assets, in
short-term fixed income obligations, index futures contracts and options
thereon.

          The Master Fund may invest in futures contracts and options on futures
contracts. To the extent that the Master Fund or Portfolio invests in futures
contracts and options thereon for other than bona fide hedging purposes, it will
not 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 its net assets, after taking into account unrealized profits
and unrealized losses on such contracts it has entered into; provided, however,
that, in the case of an option that is in-the-money at the time of purchase, the
in-the-money amount may be excluded in calculating the 5%.

individuals listed above serve as directors.


                              SERVICES TO THE FUND

ADMINISTRATIVE SERVICES

          The Fund has entered into an administration agreement with the Advisor
on behalf of the Portfolio. Pursuant to the administration agreement, the
Advisor will perform various services, including: supervision of the services
provided by the Portfolio's custodian and dividend disbursing agent and others
who provide services to the Fund for the benefit of the Portfolio; assisting the
Fund in complying with the provisions of federal, state, local and foreign
securities, tax and other laws applicable to the Portfolio; providing
shareholders with information about the Portfolio and their investments as they
or the Fund may request; assisting the Portfolio in conducting meetings of
shareholders of record; furnishing information as the Board of Directors may
require regarding the Master Fund; and any other administrative services for the
benefit of the Portfolio as the Board of Directors may reasonably request. The
Advisor also provides the Fund with office space and personnel. For its
administrative services, the Portfolio pays the Advisor a monthly fee equal to
one-twelfth of 0.025% of the average net assets of the Portfolio. The Advisor,
in conjunction with other service providers to the Portfolio and Master Fund,
has agreed to waive its fee under the administration agreement and, to the
extent that such waiver is insufficient, to assume expenses of the Portfolio to
the extent necessary to keep the cumulative annual expenses to not more than
0.10% of the average net assets of the Portfolio on an annualized basis. The
Advisor retains the right in its sole discretion to modify or eliminate the
waiver of a portion of its fees and assumption of expenses in the future.

          PFPC Inc. ("PFPC"), 400 Bellevue Parkway, Wilmington, DE 19809, serves
as the accounting services, dividend disbursing and transfer agent for the
Portfolio and the Master Fund. The services provided by PFPC are subject to
supervision by the executive officers and the Board of Directors of the Fund and
include day-to-day keeping and maintenance of certain records, calculation of
the offering price of the shares, preparation of reports, liaison with its
custodian, and transfer and dividend disbursing agency services. For its
services, the Portfolio pays PFPC a monthly fee of $1,000.



                                       8

CUSTODIAN

          PFPC Trust Company, 400 Bellevue Parkway, Wilmington, DE 19809, serves
as a custodian for the Portfolio and the Master Fund. The custodian maintains a
separate account or accounts for the Portfolio and the Master Fund; receives,
holds and releases portfolio securities on account of the Portfolio and the
Master Fund; makes receipts and disbursements of money on behalf of the
Portfolio and the Master Fund; and collects and receives income and other
payments and distributions on account of the Portfolio's and Master Fund's
portfolio securities.

DISTRIBUTOR

                  The Fund acts as distributor of the Portfolio's shares. It
has, however, entered into an agreement with DFA Securities Inc., a wholly owned
subsidiary of DFA, pursuant to which DFA Securities Inc. is responsible for
supervising the sale of the Portfolio's shares. No compensation is paid by the
Fund to DFA Securities Inc. under this agreement.

LEGAL COUNSEL

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


                                  ADVISORY FEES

          David G. Booth and Rex A. Sinquefield, as directors and officers of
the Advisor and shareholders of the Advisor's outstanding stock, may be deemed
controlling persons of the Advisor. For the services it provides as investment
advisor to the Master Fund, the Advisor is paid a monthly fee calculated as a
percentage of average net assets of the Master Fund. For the fiscal years ended
November 30, 1996, 1997 and 1998, the Master Fund paid advisory fees of $62,000,
$160,000 and $293,000, respectively. The Master Fund has more than one investor;
this dollar amount represents the total dollar amount of advisory fees paid by
the Master Fund to the Advisor.


                               GENERAL INFORMATION

          The Fund was incorporated under Maryland law on March 19, 1990. The
Fund was known as DFA U.S. Large Cap Inc. from February, 1992, until it amended
its Articles of Incorporation in April, 1993, to change to its present name.
Prior to a February, 1992, amendment to the Articles of Incorporation, it was
known as DFA U.S. Large Cap Portfolio Inc. 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.


                               SHAREHOLDER RIGHTS

          The shares of the Portfolio, when issued and paid for in accordance
with the Portfolio's prospectus, will be fully paid and non-assessable shares,
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
portfolio. Ordinarily, the Fund does not intend to hold annual meetings of
shareholders, except as required by the 1940 Act or other applicable law. The
Fund's by-laws 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



                                       9
<PAGE>

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.

          Whenever the Portfolio, as an investor in the Master Fund, is asked to
vote on a shareholder proposal, the Fund will solicit voting instructions from
the Portfolio's shareholders with respect to the proposal. The Directors of the
Fund will then vote the Portfolio's shares in the Master Fund in accordance with
the voting instructions received from the Portfolio's shareholders. The
Directors of the Fund will vote shares of the Portfolio for which they receive
no voting instructions in accordance with their best judgment.

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

                         PRINCIPAL HOLDERS OF SECURITIES

          As of August 31, 1999, the following person(s) beneficially owned
5% or more of the outstanding stock of the Portfolio:

          [Principal Holders as of August 31, 1999 will be included in the
filing of 485(b) prior to the effective date.]

                               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 (the "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 it is open on Good Friday and closed on Columbus Day and Veterans' Day.
Orders for redemptions and purchases will not be processed if the Fund is
closed.

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


                              REDEMPTION 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 U.S. Securities and Exchange Commission
("SEC"), (2) during any period when an emergency exists as defined by the rules
of the SEC as a result of which it is not reasonably practicable for the Fund to
dispose of securities owned by it, or fairly to determine the value of its
assets, and (3) for such other periods as the SEC may permit.



                                       10
<PAGE>

          Shareholders may transfer shares of the 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.


                            TAXATION OF THE PORTFOLIO

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

DISTRIBUTION OF NET INCOME

          The Portfolio receives income generally in the form of dividends and
interest on its investments. This income, less expenses incurred in the
operation of the Portfolio, constitutes its net investment income from which
dividends may be paid to its shareholders. Any distributions by the Portfolio
from such income will be taxable to a shareholder as ordinary income, whether
they are received in cash or in additional shares.

DISTRIBUTIONS OF CAPITAL GAINS

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

ELECTION TO BE TAXED AS A REGULATED INVESTMENT COMPANY

          The Portfolio intends to qualify each year as a regulated investment
company by satisfying certain distribution and asset diversification
requirements under the Internal Revenue Code. As a regulated investment company,
the Portfolio generally pays no federal income tax on the income and gains it
distributes to its shareholders. The Board reserves the right not to maintain
the qualification of the Portfolio as a regulated investment company, if it
determines such course of action to be beneficial to shareholders. In such case,
the Portfolio will be subject to federal, and possibly state, corporate taxes on
its taxable income and gains, and distributions to shareholders will be taxed as
ordinary dividend income to the extent of the Portfolio's available earnings and
profits.

EXCISE TAX DISTRIBUTION REQUIREMENT

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



                                       11
<PAGE>

REDEMPTION OF PORTFOLIO SHARES

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

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

U.S. GOVERNMENT OBLIGATIONS

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

COMPLEX SECURITIES

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

OTHER SPECIAL RULES APPLICABLE TO FEEDER PORTFOLIOS WHICH INVEST IN MASTER FUNDS

          The Portfolio may be subject to certain special rules since the Master
Fund in which the Portfolio invests is taxable as a registered investment
company ("RIC"). For example, the Portfolio will not be permitted to passthrough
foreign withholding taxes paid by the Master Fund to the Portfolio's
shareholders. These special rules may affect the amount, timing or character of
the income distributed to shareholders of the Portfolio.

INFORMATION ON THE TAX CHARACTER OF DISTRIBUTIONS

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


                         CALCULATION OF PERFORMANCE DATA

          The Portfolio and the Master Fund 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 are computed in accordance



                                       12
<PAGE>

with SEC Guidelines and are presented whenever any non-standard quotations are
disseminated. Non-standardized total return quotations may differ from the SEC
Guideline computations by covering different time periods. In all cases,
disclosures are made when performance quotations differ from the SEC Guidelines.
Performance data is based on historical earnings and is not intended to indicate
future performance. 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.

          For purposes of calculating the performance of the Portfolio, the
performance of the Master Fund will be utilized for the period prior to when the
Portfolio commenced operations, and, if applicable, restated to reflect the
Portfolio's fees and expenses. Quotations of the annualized percentage total
returns of the Master Fund for the one-, five-, and ten-year periods ended
November 30, 1998 (as applicable) are set forth in the prospectus. Such
quotations use the standardized method of calculation required by the SEC. The
Trust's annual and semi-annual reports to shareholders of the Master Fund for
the fiscal year ended November 30, 1998 and the period ended May 31, 1999,
contain additional performance information. A copy of the annual and semi-annual
reports are available upon request and without charge.

          As the following formula indicates, the Portfolio and Master Fund each
determines its average annual total return 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 calculation also assumes the account was completely redeemed at the
end of each period and the deduction of all applicable charges and fees.
According to the SEC's 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
required by the SEC, the Portfolio and Master Fund may disseminate other
performance data and may advertise total return calculated on a monthly basis.

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

                    stockholders to which such person would otherwise be
                    subject by reason or willful misfeasance, bad faith, gross
                    negligence, or reckless disregard of the duties involved in
