Risk:&lt;/span&gt;&lt;span style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; font-style:normal; font-weight:normal; text-decoration:none;"&gt; Derivatives are instruments, such as futures contracts, and options thereon,
whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging
purposes may be considered to carry more risk than other types of investments. When a fund uses derivatives,
the fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject
to a number of risks including counterparty, liquidity, interest rate, market, credit and management
risks, as well as the risk of improper valuation. Changes in the value of a derivative may not correlate
perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount
invested. &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Securities lending involves the risk that the borrower may fail to return the securities in a timely
manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned
securities. A fund could also lose money if it does not recover the securities and/or the value of the
collateral falls, including the value of investments made with cash collateral. Securities lending also
may have certain adverse tax consequences.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

DFA International Value Portfolio invests substantially all of its assets in the DFA International Value
Series. To achieve the Portfolio&#x2019;s and Series&#x2019; investment objectives, the Advisor implements
an integrated investment approach that combines research, portfolio design, portfolio management, and
trading functions. As further described below, the Series&#x2019; design emphasizes long-term drivers
of expected returns identified by the Advisor&#x2019;s research, while balancing risk through broad diversification
across companies and sectors. The Advisor&#x2019;s portfolio management and trading processes further
balance those long-term drivers of expected returns with shorter-term drivers of expected returns and
trading costs.&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The DFA International Value Series is designed to purchase
securities of large non-U.S. companies in countries with developed markets that the Advisor determines
to be lower relative price stocks. A company&#x2019;s market capitalization is the number of its shares
outstanding times its price per share. Under a market capitalization weighted approach, companies with
higher market capitalizations generally represent a larger proportion of the Series than companies with
relatively lower market capitalizations. The Advisor may overweight certain stocks, including smaller
companies, lower relative price stocks, and/or higher profitability stocks within the large-cap value
segment of developed ex U.S. markets. An equity issuer is considered to have a low relative price (i.e.,
a value stock) primarily because it has a low price in relation to its book value. In assessing relative
price, the Advisor may consider additional factors such as price to cash flow or price to earnings ratios.
An equity issuer is considered to have high profitability because it has high earnings or profits from
operations in relation to its book value or assets. The criteria the Advisor uses for assessing relative
price and profitability are subject to change from time to time.&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The DFA International
Value Series intends to purchase securities of large companies associated with developed market countries
that the Advisor has designated as approved markets. The Advisor determines the minimum market capitalization
of a large company with respect to each country or region in which the Series invests. Based on market
capitalization data as of December 31, 2024, for the Series, the market capitalization of a large company
in any country or region in which the Series invests would be $1,331 million or above. This threshold
will change due to market conditions.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The Advisor may also increase
or reduce the DFA International Value Series&#x2019; exposure to an eligible company, or exclude a company,
based on shorter-term considerations, such as a company&#x2019;s price momentum and short-run reversals.
In addition, the Advisor seeks to reduce trading costs using a flexible trading approach that looks for
opportunities to participate in the available market liquidity, while managing turnover and explicit
transaction costs.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The DFA International Value Series may gain exposure to companies
associated with approved markets by purchasing equity securities in the form of depositary receipts,
which may be listed or traded outside the issuer&#x2019;s domicile country. The Series and the DFA International
Value Portfolio each may purchase or sell futures contracts and options on futures contracts for foreign
or U.S. equity securities and indices to increase or decrease equity market exposure based on actual
or expected cash inflows to or outflows from the Series or Portfolio. Because many of the Series&#x2019;
and Portfolio&#x2019;s investments may be denominated in foreign currencies, the Series and the Portfolio
may enter into foreign currency exchange transactions, including foreign currency forward contracts,
in connection with the settlement of foreign securities or to transfer cash balances from one currency
to another currency.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The DFA International Value Series may lend its portfolio

such as futures contracts, and options thereon, and foreign currency forward contracts, whose value is
derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes
may be considered to carry more risk than other types of investments. When a fund uses derivatives, the
fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to
a number of risks including counterparty, settlement, liquidity, interest rate, market, credit and management
risks, as well as the risk of improper valuation. Changes in the value of a derivative may not correlate
perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount
invested. &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Securities lending involves the risk that the borrower may fail to return the securities in a timely
manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned
securities. A fund could also lose money if it does not recover the securities and/or the value of the
collateral falls, including the value of investments made with cash collateral. Securities lending also
may have certain adverse tax consequences.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Two-Year Portfolio seeks to maximize total returns from a universe of high quality, U.S. issued, dollar-denominated
fixed income securities maturing in three years or less from the date of settlement. The Portfolio may
invest in U.S. government obligations, U.S. government agency obligations, dollar-denominated obligations
of foreign issuers issued in the U.S., securities of domestic or foreign issuers denominated in U.S.
dollars but not trading in the U.S., foreign government and agency obligations, bank obligations, including
U.S. subsidiaries and branches of foreign banks, corporate obligations, commercial paper, repurchase
agreements, money market funds and obligations of supranational organizations. The weighted average maturity
of the Portfolio&#x2019;s investments will not exceed two years. In making purchase decisions, if the
expected term premium is greater for longer-term securities in the eligible maturity range, the Advisor
will focus investment in the longer-term area, otherwise, the Portfolio will focus investment in the
shorter-term area of the eligible maturity range. The Portfolio principally invests in certificates of
deposit, commercial paper, bankers&#x2019; acceptances, notes and bonds. The fixed income securities in
which the Portfolio invests are considered investment grade at the time of purchase (e.g., rated AAA
to BBB- by S&amp;amp;P Global Ratings (&#x201c;S&amp;amp;P&#x201d;) or Fitch Ratings Ltd. (&#x201c;Fitch&#x201d;)
or Aaa to Baa3 by Moody&#x2019;s Investor&#x2019;s Service, Inc. (&#x201c;Moody&#x2019;s&#x201d;)). In addition,
the Portfolio is authorized to invest more than 25% of its total assets in U.S. Treasury bonds, bills
and notes, and obligations of federal agencies and instrumentalities.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;As a non-fundamental policy,
under normal circumstances, the Two-Year Portfolio will invest at least 80% of its net assets in fixed
income securities that mature within two years from the date of settlement.&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The
Two-Year Portfolio may invest in futures contracts, options on futures contracts, and swaps. The Portfolio
may use fixed income related futures and options contracts, swaps and other types of derivatives to hedge
against changes in interest rates. To the extent that it 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 Portfolio may purchase or sell futures contracts and options
on futures contracts, to hedge its interest rate exposure or for non-hedging purposes, such as a substitute
for direct investment or to increase or decrease market exposure based on actual or expected cash inflows
to or outflows from the Portfolio.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The Two-Year Portfolio may lend

because the prices of fixed income securities tend to move in the opposite direction of interest rates.
When interest rates rise, fixed income security prices fall. During periods of very low or negative interest
rates, a fund may be subject to a greater risk of rising interest rates. When interest rates fall, fixed
income security prices rise. In general, fixed income securities with longer maturities are more sensitive

risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal
when due. A downgrade to an issuer&#x2019;s credit rating or a perceived change in an issuer&#x2019;s financial
strength may affect a security&#x2019;s value, and thus, impact the performance of a fund holding such
securities. Government agency obligations have different levels of credit support and, therefore, different
degrees of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that
are supported by the full faith and credit of the United States, such as the Federal Housing Administration
and Ginnie Mae, present little credit risk. Other securities issued by agencies and instrumentalities
sponsored by the U.S. Government, that are supported only by the issuer&#x2019;s right to borrow from
the U.S. Treasury, subject to certain limitations, and securities issued by agencies and instrumentalities
sponsored by the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie
Mac and Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities
issued or guaranteed by the credit of the agency may still involve a risk of non-payment of principal
and/or interest.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

such as swaps, futures contracts, and options thereon, whose value is derived from that of other assets,
rates or indices. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment
position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there
is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can
also reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated
by a fund or if the cost of the derivative outweighs the benefit of the hedge. The use of derivatives
for non-hedging purposes may be considered to carry more risk than other types of investments. When a
fund uses derivatives, the fund will be directly exposed to the risks of those derivatives. Derivative
instruments are subject to a number of risks including counterparty, settlement, liquidity, interest
rate, market, credit and management risks, as well as the risk of improper valuation. Changes in the
value of a derivative may not correlate perfectly with the underlying asset, rate or index, and a fund
could lose more than the principal amount invested. Additional risks are associated with the use of swaps
including counterparty and credit risk (the risk that the other party to a swap agreement will not fulfill
its contractual obligations, whether because of bankruptcy or other default) and liquidity risk (the
possible lack of a secondary market for the swap agreement). Credit risk increases when a fund is the
seller of swaps and counterparty risk increases when the fund is a buyer of swaps. In addition, where
a fund is the seller of swaps, it may be required to liquidate portfolio securities at inopportune times
in order to meet payment obligations. Swaps may be illiquid or difficult to value. &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

particular portfolio investments are difficult to purchase or sell. To the extent that a fund holds illiquid
investments, the fund&#x2019;s performance may be reduced due to an inability to sell the investments
at opportune prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase
by a fund due to low trading volume, adverse investor perceptions and/or other market developments. Liquidity
risk includes the risk that a fund will experience significant net redemptions at a time when it cannot
find willing buyers for its portfolio securities or can only sell its portfolio securities at a material
loss or at increased costs. &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;Liquidity risk can be more pronounced in periods of market turmoil or in situations

returns from a universe of obligations of the U.S. Government and its agencies maturing in three years
or less from the date of settlement. The weighted average maturity of the Portfolio&#x2019;s investments
will not exceed two years. In making purchase decisions, if the expected term premium is greater for
longer-term securities in the eligible maturity range, Dimensional Fund Advisors LP (the &#x201c;Advisor&#x201d;)
will focus investment in the longer-term area, otherwise, the Portfolio will focus investment in the
shorter-term area of the eligible maturity range. The credit quality of the securities purchased by the
Portfolio will be that of the U.S. Government or its agencies. The Portfolio also may enter into repurchase
agreements backed by U.S. government securities. The Portfolio may also invest in money market funds.
In addition, the Portfolio is authorized &lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;to invest more than 25% of its total assets in U.S. Treasury bonds, bills and

Two-Year Government Portfolio may invest in futures contracts, options on futures contracts, and swaps.
The Portfolio may use fixed income related futures and options contracts, swaps and other types of derivatives

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 Portfolio may purchase or sell futures contracts
and options on futures contracts, to hedge its interest rate exposure or for non-hedging purposes, such

fixed income securities tend to move in the opposite direction of interest rates. When interest rates
rise, fixed income security prices fall. During periods of very low or negative interest rates, a fund
may be subject to a greater risk of rising interest rates. When interest rates fall, fixed income security
prices rise. In general, fixed income securities with longer maturities are more sensitive to changes
in interest rates.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal
when due. A downgrade to an issuer&#x2019;s credit rating or a perceived change in an issuer&#x2019;s financial
strength may affect a security&#x2019;s value, and thus, impact the performance of a fund holding such
securities. Government agency obligations have different levels of credit support and, therefore, different
degrees of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that
are supported by the full faith and credit of the United States, such as the Federal Housing Administration
and Ginnie Mae, present little credit risk. Other securities issued by agencies and instrumentalities
sponsored by the U.S. Government, that are supported only by the issuer&#x2019;s right to borrow from
the U.S. Treasury, subject to certain limitations, and securities issued by agencies and instrumentalities
sponsored by the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie
Mac and Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities
issued or guaranteed by the credit of the agency may still involve a risk of non-payment of principal
and/or interest.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Derivatives are instruments, such as swaps, futures contracts, and options thereon, whose value is derived
from that of other assets, rates or indices. Derivatives can be used for hedging (attempting to reduce
risk by offsetting one investment position with another) or non-hedging purposes. Hedging with derivatives
may increase expenses, and there is no guarantee that a hedging strategy will work. While hedging can
reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the market moves
in a manner different from that anticipated by a fund or if the cost of the derivative outweighs the
benefit of the hedge. The use of derivatives for non-hedging purposes may be considered to carry more
risk than other types of investments. When a fund uses derivatives, the fund will be directly exposed
to the risks of those derivatives. Derivative instruments are subject to a &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;number of risks including counterparty, liquidity, interest rate, market, credit
and management risks, as well as the risk of improper valuation. Changes in the value of a derivative
may not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than
the principal amount invested. Additional risks are associated with the use of swaps including counterparty
and credit risk (the risk that the other party to a swap agreement will not fulfill its contractual obligations,
whether because of bankruptcy or other default) and liquidity risk (the possible lack of a secondary
market for the swap agreement). Credit risk increases when a fund is the seller of swaps and counterparty
risk increases when the fund is a buyer of swaps. In addition, where a fund is the seller of swaps, it
may be required to liquidate portfolio securities at inopportune times in order to meet payment obligations.
Swaps may be illiquid or difficult to value. &lt;/p&gt;</rr:RiskTextBlock>

are difficult to purchase or sell. To the extent that a fund holds illiquid investments, the fund&#x2019;s
performance may be reduced due to an inability to sell the investments at opportune prices or times.
Liquid portfolio investments may become illiquid or less liquid after purchase by a fund due to low trading
volume, adverse investor perceptions and/or other market developments. Liquidity risk includes the risk
that a fund will experience significant net redemptions at a time when it cannot find willing buyers
for its portfolio securities or can only sell its portfolio securities at a material loss or at increased
costs. Liquidity risk can be more pronounced in periods of market turmoil or in situations where ownership
of shares of a fund are concentrated in one or a few investors. &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also

Example is meant to help you compare the cost of investing in the Portfolio with the cost of investing
in other funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated.
The Example also assumes that your investment has a 5% return each year and that the Portfolio&#x2019;s operating
expenses remain the same. The costs for the Portfolio reflect the net expenses of the Portfolio that
result from the contractual expense waiver in the first year only. Although your actual costs may be
higher or lower, based on these assumptions your costs whether you redeem or hold your shares would be:

objectives, the Advisor implements an integrated investment approach that combines research, portfolio

the Underlying Funds&#x2019; designs emphasize long-term drivers of expected returns identified by the Advisor&#x2019;s
research, while balancing risk through broad diversification across companies and sectors. The Advisor&#x2019;s
portfolio management and trading processes further balance those long-term drivers of expected returns

Global Equity Portfolio is designed to provide exposure to a broad portfolio of securities of both U.S.
companies and non-U.S. companies associated with countries with developed and emerging markets, primarily
by purchasing shares of the Underlying Funds. In addition, the Portfolio further diversifies its investment
portfolio by allocating its assets among Underlying Funds that provide exposure to companies in all market
capitalization ranges, as well as real estate securities. Periodically the Advisor will review the allocations
for the Portfolio in each Underlying Fund and may adjust allocations to the Underlying Funds or may add
or remove Underlying Funds in the Portfolio without notice to shareholders.&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;As

a broad and diverse portfolio of securities of U.S. operating companies of all market capitalization
sizes with a moderate to meaningful emphasis on smaller capitalization, lower relative price, and higher
profitability companies and a domestic equity Underlying Fund that primarily invests in publicly traded
REITs. The Portfolio also purchases international equity Underlying Funds that purchase a broad and diverse
portfolio of securities of companies in developed and emerging markets of all market capitalization sizes
with a meaningful emphasis on smaller capitalization, lower relative price, and higher profitability
companies and an international equity Underlying Fund that primarily invests in publicly traded REITs
and REIT-like entities.&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The Portfolio, directly or indirectly through its investment

Advisor may also increase or reduce the Global Equity Portfolio&#x2019;s and/or Underlying Funds&#x2019; exposure
to an eligible company, or exclude a company, based on shorter-term considerations, such as a company&#x2019;s
price momentum, short-run reversals, and investment characteristics. In assessing a company&#x2019;s investment
characteristics, the Advisor considers ratios such as recent changes in assets divided by total assets.
The criteria the Advisor uses for assessing a company&#x2019;s investment characteristics are subject to change
from time to time. In addition, the Advisor seeks to reduce trading costs using a flexible trading approach
that looks for opportunities to participate in the available market liquidity, while managing turnover
and explicit transaction costs.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:12.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Global Equity Portfolio
and each Underlying Fund may purchase and sell futures contracts and options on futures contracts for
foreign or U.S. equity securities and indices to increase or decrease equity market exposure based on
actual or expected cash inflows to or outflows from the Portfolio or Underlying Funds. Certain Underlying
Funds may enter into foreign currency exchange transactions, including foreign currency forward contracts
to hedge foreign currency risks, to hedge against fluctuations in currency exchange rates, or to transfer
balances from one currency to another. Also the Portfolio and Underlying Funds may lend their portfolio
securities to generate additional income.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; font-style:normal; font-weight:normal; text-decoration:none;"&gt;A summary

investment performance of a fund of funds is affected by the investment performance of the underlying
funds in which the fund of funds invests. The ability of a fund of funds to achieve its investment objective
depends on the ability of the underlying funds to meet their investment objectives and on the Advisor&#x2019;s
decisions regarding the allocation of a fund of funds&#x2019; assets among the underlying funds. A fund of
funds may allocate assets to an underlying fund or asset class that underperforms other funds or asset
classes.  There can be no assurance that the investment objective of a fund of funds or any underlying
fund will be achieved. Through its investments in the underlying funds, a fund of funds is subject to
the risks of the underlying funds&#x2019; investments. When a fund of funds invests in underlying funds, investors
are exposed to a proportionate share of the expenses of those underlying funds in addition to the expenses
of a fund of funds. Certain risks of the Underlying Funds&#x2019; investments that are principal risks of
investing in the Portfolio are described below.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar).&lt;/span&gt;&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;Foreign issuers may not
be subject to uniform accounting, auditing and financial reporting standards and there may be less reliable
and publicly available financial and other information about such issuers, as compared to U.S. issuers.
A fund may have greater difficulty voting proxies, exercising shareholder rights, securing dividends
and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing legal
remedies, and obtaining judgments with respect to foreign investments in foreign courts than with respect
to domestic issuers in U.S. courts.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;Depositary receipts are generally
subject to the same risks as the foreign securities that they evidence or into which they may be converted.
In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered
depositary receipts, are under no obligation to distribute shareholder communications to the holders
of such receipts, or to pass through to them any voting rights with respect to the deposited securities.
Depositary receipts that are not sponsored by the issuer may be less liquid and there may be less readily
available public information about the issuer.&lt;/p&gt;</rr:RiskTextBlock>

a small or mid-cap company security at a desired time or price. As a result, small and mid-cap company
stocks may fluctuate relatively more in price. In general, small and mid-capitalization companies are
also more vulnerable than larger companies to adverse business or economic developments and they may
have more limited resources.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

such as futures contracts, and options thereon, and foreign currency forward contracts, whose value is
derived from that of other assets, rates or indices. Derivatives can be used for hedging (attempting
to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with
derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While
hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the
market moves in a manner different from that anticipated by a fund or if the cost of the derivative outweighs
the benefit of the hedge. In regard to currency hedging, it is generally not possible to precisely match
the foreign currency exposure of such foreign currency forward contracts to the value of the securities
involved due to fluctuations in the market values of such securities and cash flows into and out of a
fund between the date a foreign currency forward contract is entered into and the date it expires. The
use of derivatives for non-hedging purposes may be considered to carry more risk than other types of
investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives.
Derivative instruments are subject to a number of risks including counterparty, settlement, liquidity,
interest rate, market, credit and management risks, as well as the risk of improper valuation. Changes
in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and
a fund could lose more than the principal amount invested. &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

60/40 Portfolio is a &#x201c;fund of funds&#x201d;, which means that the Portfolio generally allocates its assets
among other funds managed by the Advisor, although it has the ability to invest directly in securities
and derivatives. The Portfolio allocates its assets to Underlying Funds that invest in equity and fixed
income securities. To achieve the Portfolio&#x2019;s and the Underlying Funds&#x2019; investment objectives, the
Advisor implements an integrated investment approach that combines research, portfolio design, portfolio
management, and trading functions. As further described below, the Portfolio&#x2019;s and the Underlying Funds&#x2019;
designs emphasize long-term drivers of expected returns identified by the Advisor&#x2019;s research, while
balancing risk through broad diversification across companies and sectors. The Advisor&#x2019;s portfolio
management and trading processes further balance those long-term drivers of expected returns with shorter-term
drivers of expected returns and trading costs.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;Generally, the Portfolio invests
its assets in domestic and international equity Underlying Funds and fixed income Underlying Funds to
achieve an allocation of approximately 40% to 80% (with a target allocation of approximately 60%) of
the Portfolio&#x2019;s assets to domestic and international equity Underlying Funds and 20% to 60% (with a
target allocation of approximately 40%) of its assets to fixed income Underlying Funds. Periodically
the Advisor will review the allocations for the Portfolio in each Underlying Fund and may adjust allocations
to the Underlying Funds or may add or remove Underlying Funds in the Portfolio without notice to shareholders.&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;In
addition to its allocation strategy of providing exposure to the domestic and international equity and
fixed income markets through investment in the Underlying Funds, the 60/40 Portfolio further diversifies
its investment portfolio by allocating its assets among Underlying Funds that represent a variety of
different asset classes. As of February 28, 2025, the Portfolio invests in: (1) domestic equity Underlying
Funds that purchase a broad and diverse portfolio of securities of U.S. operating companies of all market
capitalization sizes with a moderate to meaningful emphasis on smaller capitalization, lower relative
price, and higher profitability companies and a domestic equity Underlying Fund that primarily invests
in publicly traded REITs; (2) international equity Underlying Funds that purchase a broad and diverse
portfolio of securities of companies in developed and emerging markets of all market capitalization sizes
with a meaningful emphasis on smaller capitalization, lower relative price, and higher profitability
companies and an international equity Underlying Fund that primarily invests in publicly traded REITs
and REIT-like entities; and (3) fixed income Underlying Funds that may purchase U.S. and foreign debt
securities such as obligations issued or guaranteed by the U.S. and foreign governments, their agencies
and instrumentalities, bank obligations, commercial paper, repurchase agreements, money market funds,
obligations of other domestic and foreign issuers, securities of domestic and foreign issuers denominated
in U.S. dollars but not trading in the United States, obligations of supranational organizations and
inflation-protected securities.&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The Portfolio, directly or indirectly through its investment
in the Underlying Funds, intends to invest its assets to gain exposure to at least three different countries,
including the United States. As of the date of the Prospectus, the Portfolio, directly or indirectly
through its investment in the Underlying Funds, invests approximately 44% of its net assets in U.S. companies
or issuers. This percentage will change due to market conditions.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The
Advisor may also increase or reduce the 60/40 Portfolio&#x2019;s and/or Underlying Funds&#x2019; exposure to an
eligible company, or exclude a company, based on shorter-term considerations, such as a company&#x2019;s price
momentum, short-run reversals, and investment characteristics. In assessing a company&#x2019;s investment
characteristics, the Advisor considers ratios such as recent changes in assets divided by total assets.
The criteria the Advisor uses for assessing a company&#x2019;s investment characteristics are subject to change
from time to time. In addition, the Advisor seeks to reduce trading costs using a flexible trading approach
that looks for opportunities to participate in the available market liquidity, while managing turnover
and explicit transaction costs.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The 60/40 Portfolio and each Underlying Fund may purchase
or sell futures contracts and options on futures contracts, to increase or decrease market exposure based
on actual or expected cash inflows to or outflows from the Portfolio or Underlying Fund. Certain Underlying
Funds may enter into foreign currency exchange transactions, including foreign currency forward contracts,
in connection with the settlement of foreign securities, to hedge foreign currency risks, to hedge against
fluctuations in currency exchange rates, or to transfer balances from one currency to another. Certain
fixed income Underlying Funds also may enter into credit default swaps on issuers or indices to buy or
sell credit protection to hedge credit exposure; gain market or issuer exposure without owning the underlying
securities; or increase the Underlying Fund&#x2019;s total return. Certain fixed income Underlying Funds also
may purchase or sell futures contracts and options on futures contracts, to hedge interest rate or currency
exposure or for non-hedging purposes, such as a substitute for direct investment or to increase or decrease
market exposure &lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;based on actual or expected cash inflows to or outflows from the Underlying Fund.
Certain fixed income Underlying Funds may use derivatives to establish short positions for individual
securities, markets, or currencies, in order to adjust the Underlying Fund&#x2019;s duration or to replace
more traditional direct investments. Also the Portfolio and Underlying Funds may lend their portfolio
securities to generate additional income.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; font-style:normal; font-weight:normal; text-decoration:none;"&gt;A summary of the investment

of the underlying funds in which the fund of funds invests. The ability of a fund of funds to achieve
its investment objective depends on the ability of the underlying funds to meet their investment objectives
and on the Advisor&#x2019;s decisions regarding the allocation of a fund of funds&#x2019; assets among the underlying
funds. A fund of funds may allocate assets to an underlying fund or asset class that underperforms other
funds or asset classes.  There can be no assurance that the investment objective of a fund of funds or
any underlying fund will be achieved. Through its investments in the underlying funds, a fund of funds
is subject to the risks of the underlying funds&#x2019; investments. When a fund of funds invests in underlying
funds, investors are exposed to a proportionate share of the expenses of those underlying funds in addition
to the expenses of a fund of funds. Certain risks of the Underlying Funds&#x2019; investments that are principal

risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal
when due. A downgrade to an issuer&#x2019;s credit rating or a perceived change in an issuer&#x2019;s financial
strength may affect a security&#x2019;s value, and thus, impact the performance of a fund holding such securities.
Government agency obligations have different levels of credit support and, therefore, different degrees
of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that are supported
by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie
Mae, present little credit risk. Other securities issued by agencies and instrumentalities sponsored
by the U.S. Government, that are supported only by the issuer&#x2019;s right to borrow from the U.S. Treasury,
subject to certain limitations, and securities issued by agencies and instrumentalities sponsored by
the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie Mac and
Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities issued
or guaranteed by the credit of the agency may still involve a risk of non-payment of principal and/or
interest. Credit risk is greater for fixed income securities with ratings below investment grade (e.g.,
BB+ or below by S&amp;amp;P or Fitch or Ba1 or below by Moody&#x2019;s). Fixed income securities that are below
investment grade involve high credit risk and are considered speculative. Below investment grade fixed
income securities may also fluctuate in value more than higher quality fixed income securities and, during
periods of market volatility, may be more difficult to sell at the time and price a fund desires.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Risk:&lt;/span&gt;&lt;span style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; font-style:normal; font-weight:normal; text-decoration:none;"&gt; Derivatives are instruments, such as swaps, futures contracts, and options thereon,
and foreign currency forward contracts, whose value is derived from that of other assets, rates or indices.
Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position
with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no
guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also
reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated
by a fund or if the cost of the derivative outweighs the benefit of the hedge. In regard to currency
hedging, it is generally not possible to precisely match the foreign currency exposure of such foreign
currency forward contracts to the value of the securities involved due to fluctuations in the market
values of such securities and cash flows into and out of a fund between the date a foreign currency forward
contract is entered into and the date it expires. The use of derivatives for non-hedging purposes may
be considered to carry more risk than other types of investments. When a fund uses derivatives, the fund
will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number
of risks including counterparty, liquidity, interest rate, market, credit and management risks, as well
as the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with
the underlying asset, rate or index, and a fund could lose more than the principal amount invested. Additional
risks are associated with the use of swaps including counterparty and credit risk (the risk that the
other party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy
or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement).
Credit risk increases when a fund is the seller of swaps and counterparty risk increases when the fund
is a buyer of swaps. In addition, where a fund is the seller of swaps, it may be required to liquidate
portfolio securities at inopportune times in order to meet payment obligations. Swaps may be illiquid
or difficult to value. &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

due to an inability to sell the investments at opportune prices or times. Liquid portfolio investments
may become illiquid or less liquid after purchase by a fund due to low trading volume, adverse investor
perceptions and/or other market developments. Liquidity risk includes the risk that a fund will experience
significant net redemptions at a time when it cannot find willing buyers for its portfolio securities
or can only sell its portfolio securities at a material loss or at increased costs. Liquidity risk can
be more pronounced in periods of market turmoil or in situations where ownership of shares of a fund
are concentrated in one or a few investors. &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

however, the Underlying Funds pay transaction costs when buying and selling securities for their portfolio.

25/75 Portfolio is a &#x201c;fund of funds&#x201d;, which means that the Portfolio generally allocates its assets
among other funds managed by the Advisor, although it has the ability to invest directly in securities
and derivatives. The Portfolio&#x2019;s allocates the majority of its assets to fixed income Underlying Funds,
but the Portfolio also allocates a small portion of its assets to domestic and international equity Underlying
Funds. To achieve the Portfolio&#x2019;s and the Underlying Funds&#x2019; investment objectives, the Advisor implements
an integrated investment approach that combines research, portfolio design, portfolio management, and
trading functions. As further described below, the Portfolio&#x2019;s and the Underlying Funds&#x2019; designs
emphasize long-term drivers of expected returns identified by the Advisor&#x2019;s research, while balancing
risk through broad diversification across companies and sectors. The Advisor&#x2019;s portfolio management
and trading processes further balance those long-term drivers of expected returns with shorter-term drivers
of expected returns and trading costs.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;Generally, the Portfolio invests its assets
in domestic and international equity Underlying Funds and fixed income Underlying Funds to achieve an
allocation of approximately 5% to 45% (with a target allocation of approximately 25%) of the Portfolio&#x2019;s
assets to domestic and international equity Underlying Funds and approximately 55% to 95% (with a target
allocation of approximately 75%) of the Portfolio&#x2019;s assets to fixed income Underlying Funds. Periodically
the Advisor will review the allocations for the Portfolio in each Underlying Fund and may adjust allocations
to the Underlying Funds or may add or remove Underlying Funds in the Portfolio without notice to shareholders.&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;In
addition to its allocation strategy of providing exposure to the domestic and international equity and
fixed income markets through investment in the Underlying Funds, the 25/75 Portfolio further diversifies
its investment portfolio by allocating its assets among Underlying Funds that represent a variety of
different asset classes. As of February 28, 2025, the Portfolio invests in: (1) fixed income Underlying
Funds that may purchase U.S. and foreign debt securities such as obligations issued or guaranteed by
the U.S. and foreign governments, their agencies and instrumentalities, bank obligations, commercial
paper, repurchase agreements, money market funds, obligations of other domestic and foreign issuers,
securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the United States,
obligations of supranational organizations and inflation-protected securities; (2) domestic equity Underlying
Funds that purchase a broad and diverse portfolio of securities of U.S. operating companies of all market
capitalization sizes with a moderate to meaningful emphasis on smaller capitalization, lower relative
price, and higher profitability companies and a domestic equity Underlying Fund that primarily invests
in publicly traded REITs; and (3) international equity Underlying Funds that purchase a broad and diverse
portfolio of securities of companies in developed and emerging markets of all market capitalization sizes
with a meaningful emphasis on smaller capitalization, lower relative price, and higher profitability
companies and an international equity Underlying Fund that primarily invests in publicly traded REITs
and REIT-like entities.&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The Portfolio, directly or indirectly through its investment
in the Underlying Funds, intends to invest its assets to gain exposure to at least three different countries,
including the United States. As of the date of the Prospectus, the Portfolio, directly or indirectly
through its investment in the Underlying Funds, invests approximately 18% of its net assets in U.S. companies
or issuers. This percentage will change due to market conditions.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The
Advisor may also increase or reduce the 25/75 Portfolio&#x2019;s and/or Underlying Funds&#x2019; exposure to an
eligible company, or exclude a company, based on shorter-term considerations, such as a company&#x2019;s price
momentum, short-run reversals, and investment characteristics. In assessing a company&#x2019;s investment
characteristics, the Advisor considers ratios such as recent changes in assets divided by total assets.
The criteria the Advisor uses for assessing a company&#x2019;s investment characteristics are subject to change
from time to time. In addition, the Advisor seeks to reduce trading costs using a flexible trading approach
that looks for opportunities to participate in the available market liquidity, while managing turnover
and explicit transaction costs.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The 25/75 Portfolio and each Underlying Fund may purchase
or sell futures contracts and options on futures contracts, to increase or decrease market exposure based
on actual or expected cash inflows to or outflows from the Portfolio or Underlying Fund. Certain Underlying
Funds may enter into foreign currency exchange transactions, including foreign currency forward contracts,
in connection with the settlement of foreign securities, to hedge foreign currency risks, to hedge against
fluctuations in currency exchange rates, or to transfer balances from one currency to another. Certain
fixed income Underlying Funds also may enter into credit default swaps on issuers or indices to buy or
sell credit protection to hedge credit exposure; gain market or issuer exposure without owning the underlying
securities; or increase the Underlying Fund&#x2019;s total return. Certain fixed income Underlying Funds also
&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;may purchase or sell futures contracts and options on futures contracts, to hedge
interest rate or currency exposure or for non-hedging purposes, such as a substitute for direct investment
or to increase or decrease market exposure, including adjustments based on actual or expected cash inflows
to or outflows from the Underlying Fund. Certain fixed income Underlying Funds may use derivatives to
establish short positions for individual securities, markets, or currencies, in order to adjust the Underlying
Fund&#x2019;s duration or to replace more traditional direct investments. Also the Portfolio and Underlying
Funds may lend their portfolio securities to generate additional income.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; font-style:normal; font-weight:normal; text-decoration:none;"&gt;A

by the investment performance of the underlying funds in which the fund of funds invests. The ability
of a fund of funds to achieve its investment objective depends on the ability of the underlying funds
to meet their investment objectives and on the Advisor&#x2019;s decisions regarding the allocation of a fund
of funds&#x2019; assets among the underlying funds. A fund of funds may allocate assets to an underlying fund
or asset class that underperforms other funds or asset classes.  There can be no assurance that the investment
objective of a fund of funds or any underlying fund will be achieved. Through its investments in the
underlying funds, a fund of funds is subject to the risks of the underlying funds&#x2019; investments. When
a fund of funds invests in underlying funds, investors are exposed to a proportionate share of the expenses
of those underlying funds in addition to the expenses of a fund of funds. Certain risks of the Underlying
Funds&#x2019; investments that are principal risks of investing in the Portfolio are described below.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

A fund may have greater difficulty voting proxies, exercising shareholder rights, securing dividends

In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered
depositary receipts, are under no obligation to distribute shareholder communications to the holders
of such receipts, or to pass through to them any voting rights with respect to the deposited securities.

have a history of, and continue to experience serious, and potentially continuing, economic and political
problems. Stock markets in many emerging market countries are relatively small, expensive to trade in
and generally have higher risks than those in developed markets. Securities in emerging markets also
may be less liquid than those in developed markets and foreigners are often limited in their ability
to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under other
conditions. Frontier market countries generally have smaller economies or less developed capital markets
and, as a result, the risks of investing in emerging market countries are magnified in frontier market
countries.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

rise, fixed income security prices fall. During periods of very low or negative interest rates, a fund

risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal
when due. A downgrade to an issuer&#x2019;s credit rating or a perceived change in an issuer&#x2019;s financial
strength may affect a security&#x2019;s value, and thus, impact the performance of a fund holding such securities.
Government agency obligations have different levels of credit support and, therefore, different degrees
of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that are supported
by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie
Mae, present little credit risk. Other securities issued by agencies and instrumentalities sponsored
by the U.S. Government, that are supported only by the issuer&#x2019;s right to borrow from the U.S. Treasury,
subject to certain limitations, and securities issued by agencies and instrumentalities sponsored by
the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie Mac and
Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities issued
or guaranteed by the credit of the agency may still involve a risk of non-payment of principal and/or
interest. Credit risk is greater for fixed income securities with ratings below investment grade (e.g.,
BB+ or below by S&amp;amp;P or Fitch or Ba1 or below by Moody&#x2019;s). Fixed income securities that are below
investment grade involve high credit risk and are considered speculative. Below investment grade fixed
income securities may also fluctuate in value more than higher quality fixed income securities and, during
periods of market volatility, may be more difficult to sell at the time and price a fund desires.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Risk:&lt;/span&gt;&lt;span style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; font-style:normal; font-weight:normal; text-decoration:none;"&gt; Derivatives are instruments, such as swaps, futures contracts, and options thereon,
and foreign currency forward contracts, whose value is derived from that of other assets, rates or indices.
Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position
with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no
guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also
reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated
by a fund or if the cost of the derivative outweighs the benefit of the hedge. In regard to currency
hedging, it is generally not possible to precisely match the foreign currency exposure of such foreign
currency forward contracts to the value of the securities involved due to fluctuations in the market
values of such securities and cash flows into and out of a fund between the date a foreign currency forward
contract is entered into and the date it expires. The use of derivatives for non-hedging purposes may
be considered to carry more risk than other types of investments. When a fund uses derivatives, the fund
will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number
of risks including counterparty, liquidity, interest rate, market, credit and management risks, as well
as the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with
the underlying asset, rate or index, and a fund could lose more than the principal amount invested. Additional
risks are associated with the use of swaps including counterparty and credit risk (the risk that the
other party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy
or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement).
Credit risk increases when a fund is the seller of swaps and counterparty risk increases when the fund
is a buyer of swaps. In addition, where a fund is the seller of swaps, it may be required to liquidate
portfolio securities at inopportune times in order to meet payment obligations. Swaps may be illiquid
or difficult to value. &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

or sell. To the extent that a fund holds illiquid investments, the fund&#x2019;s performance may be reduced
due to an inability to sell the investments at opportune prices or times. Liquid portfolio investments
may become illiquid or less liquid after purchase by a fund due to low trading volume, adverse investor
perceptions and/or other market developments. Liquidity risk includes the risk that a fund will experience
significant net redemptions at a time when it cannot find willing buyers for its portfolio securities
or can only sell its portfolio securities at a material loss or at increased costs. Liquidity risk can
be more pronounced in periods of market turmoil or in situations where ownership of shares of a fund
are concentrated in one or a few investors. &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

of its assets in the International Value Series. To achieve the Portfolio&#x2019;s and Series&#x2019; investment
objectives, the Advisor implements an integrated investment approach that combines research, portfolio
design, portfolio management, and trading functions. As further described below, the Series&#x2019; design
emphasizes long-term drivers of expected returns identified by the Advisor&#x2019;s research, while balancing
risk through broad diversification across companies and sectors. The Advisor&#x2019;s portfolio management
and trading processes further balance those long-term drivers of expected returns with shorter-term drivers
of expected returns and trading costs.&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The International Value Series
is designed to purchase securities of large non-U.S. companies in countries with developed markets that
the Advisor determines to be lower relative price stocks. A company&#x2019;s market capitalization is the
number of its shares outstanding times its price per share. Under a market capitalization weighted approach,
companies with higher market capitalizations generally represent a larger proportion of the Series than
companies with relatively lower market capitalizations. The Advisor may overweight certain stocks, including
smaller companies, lower relative price stocks, and/or higher profitability stocks within the large-cap
value segment of developed ex U.S. markets. An equity issuer is considered to have a low relative price
(i.e., a value stock) primarily because it has a low price in relation to its book value. In assessing
relative price, the Advisor may consider additional factors such as price to cash flow or price to earnings
ratios. An equity issuer is considered to have high profitability because it has high earnings or profits
from operations in relation to its book value or assets. The criteria the Advisor uses for assessing
relative price and profitability are subject to change from time to time.&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The
International Value Series intends to purchase securities of large companies associated with developed
market countries that the Advisor has designated as approved markets. The Advisor determines the minimum
market capitalization of a large company with respect to each country or region in which the Series invests.
Based on market capitalization data as of December 31, 2024, for the Series, the market capitalization
of a large company in any country or region in which the Series invests would be $1,331 million or above.
This threshold will change due to market conditions.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The Advisor may also increase
or reduce the International Value Series&#x2019; exposure to an eligible company, or exclude a company, based
on shorter-term considerations, such as a company&#x2019;s price momentum and short-run reversals. In addition,
the Advisor seeks to reduce trading costs using a flexible trading approach that looks for opportunities
to participate in the available market liquidity, while managing turnover and explicit transaction costs.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The
International Value Series may gain exposure to companies associated with approved markets by purchasing
equity securities in the form of depositary receipts, which may be listed or traded outside the issuer&#x2019;s
domicile country. The Series and the International Value Portfolio each may purchase or sell futures
contracts and options on futures contracts for foreign or U.S. equity securities and indices to increase
or decrease equity market exposure based on actual or expected cash inflows to or outflows from the Series
or Portfolio. Because many of the Series&#x2019; and Portfolio&#x2019;s investments may be denominated in foreign
currencies, the Series and the Portfolio may enter into foreign currency exchange transactions, including
foreign currency forward contracts, in connection with the settlement of foreign securities or to transfer
cash balances from one currency to another currency.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The International Value
Series may lend its portfolio securities to generate additional income.&lt;/p&gt;</rr:StrategyNarrativeTextBlock>

(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Series does not hedge foreign currency risk.&lt;/span&gt;&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;Foreign

dividends and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing
legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with

to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited

be less readily available public information about the issuer.&lt;/p&gt;</rr:RiskTextBlock>

may be considered to carry more risk than other types of investments. When a fund uses derivatives, the

a number of risks including counterparty, settlement, liquidity, interest rate, market, credit and management
risks, as well as the risk of improper valuation. Changes in the value of a derivative may not correlate

by investing substantially all of its assets in the U.S. Value Series. To achieve the Portfolio&#x2019;s and
the Series&#x2019; investment objectives, the Advisor implements an integrated investment approach that combines
research, portfolio design, portfolio management, and trading functions. As further described below,
the Series&#x2019; design emphasizes long-term drivers of expected returns identified by the Advisor&#x2019;s research,
while balancing risk through broad diversification across companies and sectors. The Advisor&#x2019;s portfolio
management and trading processes further balance those long-term drivers of expected returns with shorter-term
drivers of expected returns and trading costs.&lt;/span&gt;&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:9.0pt; font-family:Serif; text-align:justify; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The U.S. Value Series is
designed to purchase a broad and diverse group of readily marketable securities of large U.S. companies
that the Advisor determines to be lower relative price stocks. A company&#x2019;s market capitalization is
the number of its shares outstanding times its price per share. Under a market capitalization weighted
approach, companies with higher market capitalizations generally represent a larger proportion of the
Series than companies with relatively lower market capitalizations. The Advisor may overweight certain
stocks, including smaller companies, lower relative price stocks, and/or higher profitability stocks
within the large-cap value segment of the U.S. market. An equity issuer is considered to have a low relative
price (i.e., a value stock) primarily because it has a low price in relation to its book value. In assessing
relative price, the Advisor may consider additional factors such as price to cash flow or price to earnings
ratios. An equity issuer is considered to have high profitability because it has high earnings or profits
from operations in relation to its book value or assets. The criteria the Advisor uses for assessing
relative price and profitability are subject to change from time to time.&lt;/span&gt;&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:9.0pt; font-family:Serif; text-align:justify; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; font-style:normal; font-weight:normal; text-decoration:none;"&gt;As a
non-fundamental policy, under normal circumstances, the U.S. Value Series will invest at least 80% of
its net assets in securities of large cap U.S. companies. The Advisor generally defines a U.S. company
as one that is listed and principally traded on a securities exchange in the United States that is deemed
appropriate by the Advisor. As of the date of this Prospectus, for purposes of the Series, the Advisor
considers large cap companies to be companies whose market capitalizations are generally in the highest
90% of total market capitalization or companies whose market capitalizations are larger than or equal
to the 1,000th largest U.S. company, whichever results in the higher market capitalization break. Total
market capitalization is based on the market capitalization of eligible U.S. operating companies listed
on a securities exchange in the United States that is deemed appropriate by the Advisor. Under the Advisor&#x2019;s
market capitalization guidelines described above, based on market capitalization data as of December
31, 2024, the market capitalization of a large cap company would be $13,601 million or above. This threshold
will change due to market conditions.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Serif; text-align:justify; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Advisor may also increase
or reduce the U.S. Value Series&#x2019; exposure to an eligible company, or exclude a company, based on shorter-term
considerations, such as a company&#x2019;s price momentum and short-run reversals. In addition, the Advisor
seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate
in the available market liquidity, while managing turnover and explicit transaction costs.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Serif; text-align:justify; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The
U.S. Value Series and the U.S. Value Portfolio each may purchase or sell futures contracts and options
on futures contracts for U.S. equity securities and indices to increase or decrease equity market exposure
based on actual or expected cash inflows to or outflows from the Series or Portfolio.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The

such as futures contracts, and options thereon, whose value is derived from that of other assets, rates
or indices. The use of derivatives for non-hedging purposes may be considered to carry more risk than
other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks
of those derivatives. Derivative instruments are subject to a number of risks including counterparty,
liquidity, interest rate, market, credit and management risks, as well as the risk of improper valuation.
Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index,
and a fund could lose more than the principal amount invested. &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

its assets in the Emerging Markets Series. To achieve the Portfolio&#x2019;s and the Series&#x2019; investment
objectives, the Advisor implements an integrated investment approach that combines research, portfolio
design, portfolio management, and trading functions. As further described below, the Series&#x2019; design
emphasizes long-term drivers of expected returns identified by the Advisor&#x2019;s research, while balancing
risk through broad diversification across companies and sectors. The Advisor&#x2019;s portfolio management
and trading processes further balance those long-term drivers of expected returns with shorter-term drivers
of expected returns and trading costs.&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The Emerging Markets Series is
designed to purchase a broad market coverage of larger companies associated with emerging markets, which
may include frontier markets (emerging market countries in an earlier stage of development) authorized
for investment by the Advisor&#x2019;s Investment Committee (&#x201c;Approved Markets&#x201d;). The Advisor&#x2019;s definition
of large varies across countries and is based primarily on market capitalization. A company&#x2019;s market
capitalization is the number of its shares outstanding times its price per share. In each country authorized
for investment, the Advisor first ranks eligible companies listed on selected exchanges based on the
companies&#x2019; market capitalizations. The Advisor then defines the minimum market capitalization for a
large company in that country. For example, based on market capitalization data as of December 31, 2024,
Mexico had a size threshold of $3,365 million or above, and the Czech Republic had a size threshold of
$1,894 million or above. These thresholds will change due to market conditions. In addition, the Advisor
may consider a company&#x2019;s size, relative price, and/or profitability relative to other eligible companies
when making investment decisions for the Emerging Markets Series. An equity issuer is considered to have
a low relative price (i.e., a value stock) primarily because it has a low price in relation to its book
value. In assessing relative price, the Advisor may consider additional factors such as price to cash
flow or price to earnings ratios. An equity issuer is considered to have high profitability because it
has high earnings or profits from operations in relation to its book value or assets. The criteria the
Advisor uses for assessing relative price and profitability are subject to change from time to time.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;As
a non-fundamental policy, under normal circumstances, the Emerging Markets Series will invest at least
80% of its net assets in emerging markets investments that are defined in the prospectus as Approved
Market securities.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The Advisor may also increase or reduce the Emerging Markets
Series&#x2019; exposure to an eligible company, or exclude a company, based on shorter-term considerations,
such as a company&#x2019;s price momentum and short-run reversals. In addition, the Advisor seeks to reduce
trading costs using a flexible trading approach that looks for opportunities to participate in the available
market liquidity, while managing turnover and explicit transaction costs.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The
Emerging Markets Series may gain exposure to companies associated with Approved Markets by purchasing
equity securities in the form of depositary receipts, which may be listed or traded outside the issuer&#x2019;s
domicile country. The Emerging Markets Series may also invest in China A-shares (equity securities of
companies listed in China) and variable interest entities (special structures that utilize contractual
arrangements to provide exposure to certain Chinese companies). The Emerging Markets Series and the Emerging
Markets Portfolio each may purchase or sell futures contracts and options on futures contracts for Approved
Market or other equity market securities and indices, including those of the United States, to increase
or decrease equity market exposure based on actual or expected cash inflows to or outflows from the Series
or Portfolio. Because many of the Emerging Markets Series&#x2019; investments may be denominated in foreign
currencies, the Series and the Portfolio may enter into foreign currency exchange transactions, including
foreign currency forward contracts, in connection with the settlement of foreign securities or to transfer
cash balances from one currency to another currency.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;The Emerging Markets Series

may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Series does not hedge foreign currency risk.&lt;/span&gt;&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;Foreign

may be less reliable and publicly available financial and other information about such issuers, as compared

dividends and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing
legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with
respect to domestic issuers in U.S. courts.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;Depositary receipts are

be converted. In addition, the underlying issuers of certain depositary receipts, particularly unsponsored
or unregistered depositary receipts, are under no obligation to distribute shareholder communications
to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited
securities. Depositary receipts that are not sponsored by the issuer may be less liquid and there may
be less readily available public information about the issuer.&lt;/p&gt;</rr:RiskTextBlock>

serious, and potentially continuing, economic and political problems. Stock markets in many emerging
market countries are relatively small, expensive to trade in and generally have higher risks than those
in developed markets. Securities in emerging markets also may be less liquid than those in developed
markets and foreigners are often limited in their ability to invest in, and withdraw assets from, these
markets. Additional restrictions may be imposed under other conditions. Frontier market countries generally
have smaller economies or less developed capital markets and, as a result, the risks of investing in
emerging market countries are magnified in frontier market countries.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

associated with investments in China, Hong Kong, and Taiwan. China, Hong Kong, and Taiwan are highly
interconnected and interdependent, with relationships and tensions built on trade, finance, culture,
and politics. Despite prior economic and trade reforms and the prior expansion of private ownership of
companies in certain sectors, the Chinese government still exercises substantial influence over many
aspects of the private sector and may own or control many companies, including by embedding Chinese Communist
Party or People&#x2019;s Armed Forces Department personnel in Chinese companies. In addition, the Chinese
government continues to maintain a major role in economic policy making and may alter or discontinue
economic or trade reforms at any time. Investing in China involves risks of losses due to expropriation,
nationalization, confiscation of assets and property, and the imposition of restrictions on foreign investments
and on repatriation of capital invested.&lt;/span&gt;&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:9.0pt; font-family:Avenir LT Pro 45 Book; text-align:justify; font-weight:normal; text-decoration:none;"&gt;Investments in China, Hong Kong,
and Taiwan are also subject to the risk of escalating tensions and deteriorating relations with the U.S.
as economic and strategic competition between the U.S. and China intensifies, which could result in further
tariffs, trade restrictions, sanctions, or other actions that adversely impact the value of such investments.
A reduction in spending on Chinese products and services, supply chain diversification or the &lt;/p&gt;

of heightened trade tensions between China and the United States may also have an adverse impact on the
Chinese economy. In addition, investments in Taiwan could be adversely affected by its political and
economic relationship with China. Certain securities issued by companies located or operating in China,
such as China A-shares, are also subject to trading restrictions, quota limitations and less market liquidity,
which could pose risks to a fund investing in such securities. In addition, investments in special structures
that utilize contractual arrangements to provide exposure to certain Chinese companies, known as variable
interest entities (&#x201c;VIEs&#x201d;), that operate in sectors in which China restricts and/or prohibits foreign
investments may present additional risks. The Chinese government&#x2019;s acceptance of the VIE structure
is evolving. It is uncertain whether Chinese officials and regulators will withdraw their acceptance
of the structure generally, or with respect to certain industries, or whether Chinese courts or arbitration
bodies would decline to enforce the contractual rights of foreign investors, each of which would likely
have significant, detrimental, and possibly permanent losses on the value of such investments.&lt;/p&gt;</rr:RiskTextBlock>

such as futures contracts, and options thereon, and foreign currency forward contracts, whose value is
derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes
may be considered to carry more risk than other types of investments. When a fund uses derivatives, the
fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to
a number of risks including counterparty, settlement, liquidity, interest rate, market, credit and management
risks, as well as the risk of improper valuation. Changes in the value of a derivative may not correlate
perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount
invested. &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Securities lending involves the risk that the borrower may fail to return the securities in a timely
manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned
securities. A fund could also lose money if it does not recover the securities and/or the value of the
collateral falls, including the value of investments made with cash collateral. Securities lending also
