fund" that invests, through the Master Portfolio, at least 99.5% of its total assets in Government securities,
cash and repurchase &lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;agreements
collateralized fully by Government securities or cash. For purposes of this policy, &#x201c;Government securities&#x201d;
means any securities issued or guaranteed as to principal or interest by the United States, or by a person
controlled or supervised by and acting as an instrumentality of the Government of the United States pursuant
to authority granted by the Congress of the United States; or any certificate of deposit for any of the
foregoing. Government securities include those issued by government agencies or instrumentalities, such
as the Federal National Mortgage Association (Fannie Mae), Federal Home Loan Mortgage Corporation (Freddie
Mac), Federal Home Loan Banks and Federal Farm Credit Banks, whose securities are neither issued nor
guaranteed by the U.S. Government. The Fund intends to be a &#x201c;Government money market fund,&#x201d; as such
term is defined in or interpreted under Rule 2a-7 under the Investment Company Act of 1940. Shareholders
will be given at least 60 days&#x2019; advance notice of any change to the 99.5% policy. &lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Fund uses the amortized
cost method of valuation to seek to maintain a stable $1.00 share price. &lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;Unless the context otherwise
requires, references to the Fund's investments refer to those investments of the Master Portfolio to
which the Fund is exposed and references to the investment manager or the Fund's investment manager refer
to the Master Portfolio's investment manager. &lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Fund invests in:&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; font-weight:bold; text-decoration:none;"&gt;U.S. government securities&lt;/span&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; font-weight:normal; text-decoration:none;"&gt; which may include fixed,

Government securities from a broker-dealer or other counterparty and then to sell the securities back
to such counterparty on an agreed upon date (generally, less than seven days) at a higher price, which
reflects prevailing short-term interest rates. &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; font-weight:bold; text-decoration:none;"&gt;Portfolio maturity and quality&lt;/span&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; font-weight:normal; text-decoration:none;"&gt;
The Fund only buys securities that the investment manager determines present minimal credit risks. The
Fund maintains a dollar-weighted average portfolio maturity of 60 calendar days or less, maintains a
dollar-weighted average life for its portfolio of 120 calendar days or less, and only buys securities
that mature or are deemed to mature in 397 calendar days or less. &lt;/span&gt;&lt;/p&gt;</rr:StrategyNarrativeTextBlock>

 Principal Risks</rr:RiskHeading>
    <rr:RiskNarrativeTextBlock contextRef="Context_S000007358Member_S000007358Summary1Member">&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;You could lose money by investing in the
Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot
guarantee it will do so. An investment in the Fund is not a bank account and is not insured or guaranteed
by the Federal Deposit Insurance Corporation or any other government agency. The Fund&#x2019;s sponsor is
not required to reimburse the Fund for losses, and &lt;/p&gt;

&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;you
should not expect that the sponsor will provide financial support to the Fund at any time, including
during periods of market stress.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; color:#004C97; font-weight:bold; text-decoration:none;"&gt;Interest Rate:&lt;/span&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; font-weight:normal; text-decoration:none;"&gt;  When interest rates rise, debt security
prices generally fall. The opposite is also generally true: debt security prices rise when interest rates
fall. Interest rate changes are influenced by a number of factors, including government policy, monetary
policy, inflation expectations, perceptions of risk, and supply of and demand for debt securities. The
Fund's yield will vary. A low interest or negative rate environment may prevent the Fund from providing
a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to
maintain a stable net asset value. A sharp and unexpected rise in interest rates could cause the Fund's
share price to drop below a dollar. In general, securities with longer maturities or durations are more
sensitive to interest rate changes. &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; color:#004C97; font-weight:bold; text-decoration:none;"&gt;Credit:&lt;/span&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; font-weight:normal; text-decoration:none;"&gt;  U.S. government investments generally
have the least credit risk but are not completely free of credit risk. The Fund may incur losses on debt
securities that are inaccurately perceived to present a different amount of credit risk by the market,
the investment manager or the rating agencies than such securities actually do. Any downgrade of securities
issued by the U.S. government may result in a downgrade of securities issued by its agencies or instrumentalities.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; color:#004C97; font-weight:bold; text-decoration:none;"&gt;Income:&lt;/span&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; font-weight:normal; text-decoration:none;"&gt;
 Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline
when prevailing interest rates fall. Because the Fund limits its investments to high-quality, short-term
securities, its portfolio generally will earn lower yields than a portfolio with lower-quality, longer-term
securities subject to more risk.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; color:#004C97; font-weight:bold; text-decoration:none;"&gt;U.S. Government Securities:&lt;/span&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; font-weight:normal; text-decoration:none;"&gt;  Not all obligations
of the U.S. Government, its agencies and instrumentalities are backed by the full faith and credit of
the United States. Some obligations are backed only by the credit of the issuing agency or instrumentality,
and in some cases there may be some risk of default by the issuer. Government agency or instrumentality
issues have different levels of credit support. &lt;/span&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; font-weight:bold; text-decoration:none;"&gt;U.S. government-sponsored entities ("GSEs"),
such as Fannie Mae and Freddie Mac, may be chartered by Acts of Congress, but their securities are neither
issued nor guaranteed by the U.S. government. Although the U.S. government has provided financial support
to Fannie Mae, Freddie Mac and certain other GSEs, no assurance can be given that the U.S. government
will continue to do so.&lt;/span&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; font-weight:normal; text-decoration:none;"&gt; Accordingly, securities issued by Fannie Mae and Freddie Mac may involve a risk
of non-payment of principal and interest. Investors should remember that guarantees of timely repayment
of principal and interest do not apply to the market prices and yields of the securities or to the net
asset value or performance of the Fund, which will vary with changes in interest rates and other market
conditions.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; color:#004C97; font-weight:bold; text-decoration:none;"&gt;Repurchase
Agreements:&lt;/span&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; font-weight:normal; text-decoration:none;"&gt;  A repurchase agreement exposes the Fund to the risk that the party that sells
the securities to the Fund may default on its obligation to repurchase such securities.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; color:#004C97; font-weight:bold; text-decoration:none;"&gt;Market:
 &lt;/span&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The
market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly
or unpredictably. The market value of a security or other investment may be reduced by market activity
or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all
investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more
buyers than sellers, prices tend to rise.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;The global outbreak of the novel strain of coronavirus, COVID-19
and its subsequent variants, has resulted in market closures and dislocations, extreme volatility, liquidity
constraints and increased trading costs. The long-term impact on economies, markets, industries and individual
issuers is not known. Some sectors of the economy and individual issuers have experienced or may experience
particularly large losses. Periods of extreme volatility in the financial markets; reduced liquidity
of many instruments; and disruptions to supply chains, consumer demand and employee availability, may
continue for some time.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; color:#004C97; font-weight:bold; text-decoration:none;"&gt;Master/Feeder Structure:&lt;/span&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; font-weight:normal; text-decoration:none;"&gt;  The Fund seeks to
achieve its investment goal by investing all of its assets in shares of the Master Portfolio. The Master
Portfolio has the same investment goal and policies as the Fund. The Fund buys shares of the Master Portfolio
at net asset value. An investment in the Fund is an indirect investment in the Master Portfolio. It is
possible that the Fund may have to withdraw its investment in the Master Portfolio if the Master Portfolio
changes its investment goal or if the Fund&#x2019;s board of trustees, at any time, considers it to be in
the Fund&#x2019;s best interest.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; color:#004C97; font-weight:bold; text-decoration:none;"&gt;Management:&lt;/span&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; font-weight:normal; text-decoration:none;"&gt;  The Fund is subject
to management risk because it is an actively managed investment portfolio. The investment manager applies
investment techniques and risk analyses in making investment decisions for the Master Portfolio, but
there can be no guarantee that these decisions will produce the desired results.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; color:#004C97; font-weight:bold; text-decoration:none;"&gt;Cybersecurity:&lt;/span&gt;&lt;span style="font-size:9.0pt; font-family:Arial; font-style:normal; font-weight:normal; text-decoration:none;"&gt;
 Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain
access to Fund assets, Fund or customer data (including private shareholder information), or proprietary
information, cause the Fund, the investment manager, authorized participants, or index providers (as
applicable) and listing exchanges, and/or their service providers (including, but not limited to, Fund
accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data
breaches, data corruption or loss of operational functionality or prevent Fund investors from purchasing,
redeeming shares or receiving distributions. The investment manager has limited ability to prevent or
mitigate cybersecurity incidents affecting third party service providers, &lt;/span&gt;&lt;/p&gt;

&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;and
such third party service providers may have limited indemnification obligations to the Fund or the investment
manager. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and
substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents.
Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value
of these securities could decline if the issuers experience cybersecurity incidents.&lt;/p&gt;&lt;p style="font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;Because technology is
frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a
chance that some risks have not been identified or prepared for, or that an attack may not be detected,
which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other funds
and business enterprises, the Fund, the investment manager, and their service providers are subject to
the risk of cyber incidents occurring from time to time.&lt;/p&gt;</rr:RiskNarrativeTextBlock>
