under the Investment Company Act of 1940. <span id="xdx_906_eoef--StrategyPortfolioConcentration_c20260727__20260727__dei--LegalEntityAxis__custom--S000002140Member_zZ9yBVs6rKn">The fund normally invests at least 80% of its net assets (plus any borrowings for investment

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 10pt">The fund intends to operate as a “government money market
fund” in accordance with Rule 2a-7. “Government money market funds” are required to invest at least 99.5% of their
total assets in cash, U.S. government securities, and/or repurchase agreements that are fully collateralized by government securities
or cash. A government security is a security issued or guaranteed as to principal or interest by the U.S. government and its agencies
or instrumentalities. A repurchase agreement is a contract under which the fund (buyer) purchases a security, usually a U.S. government
or agency security, from a bank or well-established securities dealer (seller) that requires the seller to repurchase the securities
from the fund at a specific price on a designated date (which is often the next business day).</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 10pt">The fund is managed to provide a stable share price of $1.00 by investing
in only U.S. dollar-denominated money market securities. Money market securities are generally high-quality, short-term obligations issued
by companies or governmental entities. The securities purchased by the fund are subject to the maturity, quality, diversification, liquidity,
and overall risk-limiting conditions and other requirements of Rule 2a-7. The fund’s weighted average maturity will not exceed 60
calendar days, the fund’s weighted average life will not exceed 120 calendar days, and the fund will not purchase any security
with a remaining maturity longer than 397 calendar days (unless otherwise permitted by Rule 2a-7, such as certain variable and
floating rate instruments).</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 10pt">In selecting securities for the fund, the portfolio manager may examine
relationships among yields of various types and maturities of government money market securities in the context of interest rate outlooks.
The fund’s yield will fluctuate with changes in short-term interest rates.</p>
The fund normally invests at least 80% of its net assets (plus any borrowings for investment
purposes) in government securities and repurchase agreements that are collateralized by government securities.
You could lose money by investing in the fund.
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.

net asset value: </b></span>The fund may not be able to maintain a stable $1.00 share price at all times. The fund’s shareholders
should not rely on or expect the fund or an affiliate to purchase distressed assets from the fund, enter into capital support agreements
with the fund, make capital infusions into the fund, or take other actions to help the fund maintain a stable $1.00 share price.</p>

a decline in the prices of fixed income securities held by the fund.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 10pt">The fund’s yield will vary; it is not fixed for a specific period
like the yield on a bank certificate of deposit. This is a disadvantage when interest rates are falling because the fund would have to
reinvest proceeds of maturing securities at lower interest rates. During periods of extremely low short-term interest rates, the fund
may not be able to maintain a positive yield. An elevated inflation environment may heighten risks associated with rising interest rates.</p>

</b></span>The fund may be subject to periods of increased redemptions that could cause the fund to sell its assets at disadvantageous
times or at a depressed value or loss, particularly during periods of declining or illiquid markets, and that could affect the fund’s
ability to maintain a stable $1.00 share price.</p>
<p id="xdx_A89_eoef--RiskTextBlock_hoef--RiskAxis__custom--LiquidityMember_zjeb0psndJi4" style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 10pt"><span style="font-family: Times New Roman, Times, Serif"><b>Liquidity:</b></span>
The fund may not be able to sell a holding in a timely manner at its current carrying value. Periods of reduced liquidity in money markets
could require the fund to liquidate its assets at inopportune times or at a depressed value, cause the fund to be unable to meet redemption
requests without dilution of the remaining shareholders’ interests in the fund, and potentially affect the fund’s ability
to maintain a $1.00 share price.</p>

quality: </b></span>An issuer of a debt instrument or a provider of credit support could suffer an adverse change in financial condition
that results in a payment default (failure to make scheduled interest or principal payments), a rating downgrade, or an inability to meet
a financial obligation. Although the fund only purchases securities that present minimal credit risk in the opinion of T. Rowe Price,
the credit quality of the fund’s holdings could change rapidly during periods of market stress.</p>

conditions:</b></span> The value of the fund’s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting
an issuer held by the fund, particular industries, or the overall securities markets. A variety of factors can increase the volatility
of the fund’s holdings and markets generally, including geopolitical developments (such as trade and tariff arrangements, sanctions,
and cybersecurity attacks), recessions, inflation, rapid interest rate changes, war, military conflict, acts of terrorism, natural disasters,
and outbreaks of infectious illnesses or other widespread public health issues (such as pandemics) and related governmental and public
responses. Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets,
while some events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Government
intervention in markets may impact interest rates, market volatility, and security pricing. These adverse developments may cause broad
declines in market value due to short-term market movements or for significantly longer periods during more prolonged market downturns.</p>

breaches:</b></span> The fund could be harmed by intentional cyberattacks and other cybersecurity breaches, including unauthorized access
to the fund’s assets, confidential information, or other proprietary information. In addition, a cybersecurity breach could cause
one of the fund’s service providers or financial intermediaries to suffer unauthorized data access, data corruption, or loss of
operational functionality. A cybersecurity breach could result in a loss for the fund or affect its ability to operate as intended either
temporarily or for an extended period, which may include limits on the ability to obtain pricing information for the fund’s investments,
calculate its net asset value, and satisfy redemptions.</p>
