PRINCIPAL STRATEGIES:
<div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: times new roman;">The Portfolio is a “money market
fund” that seeks to maintain a stable net asset value, or NAV, of $1.00 per share although there is no guarantee that the Portfolio
will maintain a NAV of $1.00 per share.</div>
<div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: times new roman;">The Portfolio invests at least 99.5%
of its total assets in cash, marketable obligations (which may bear adjustable rates of interest) issued or guaranteed by the U.S. Government,
its agencies or instrumentalities (“U.S. Government securities”) and repurchase agreements that are collateralized fully.
Collateralized fully means collateralized by cash or government securities.</div>
<div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: times new roman;">The
Portfolio also invests at least 80%, and normally substantially all, of its net assets in U.S. Government securities and repurchase agreements
that are collateralized by U.S. Government securities. This policy may not be changed without 60 days’ prior written notice to shareholders.</div>
<div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: times new roman;">As a money market fund, the Portfolio
must meet the requirements of Securities and Exchange Commission (“SEC”) Rule 2a-7. The Rule imposes strict conditions
on the investment quality, maturity, diversification, and liquidity of the Portfolio’s investments. Among other things, Rule 2a-7
requires that the Portfolio’s investments have (i) a remaining maturity of no more than 397 days unless otherwise permitted
by Rule 2a-7, (ii) a dollar weighted average maturity of no more than 60 days, and (iii) a dollar weighted average life to maturity
of no more than 120 days. Rule 2a-7 imposes liquidity standards that require the Portfolio to hold at least 25% and 50% of its total assets
in daily liquid assets and weekly liquid assets, respectively, as defined in Rule 2a-7. Rule 2a-7 also limits the Portfolio’s
investments in illiquid securities to 5% of its total assets.</div>
<div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: times new roman;">The Portfolio may also invest in when-issued
securities related to the types of securities in which it is permitted to invest and the securities of other money market funds to the
extent permitted under the Investment Company Act of 1940, as amended.</div>
The
Portfolio also invests at least 80%, and normally substantially all, of its net assets in U.S. Government securities and repurchase agreements
that are collateralized by U.S. Government securities. This policy may not be changed without 60 days’ prior written notice to shareholders.

<div style="margin-top: 0pt; margin-bottom: 0pt; font-family: times new roman; font-size: 10pt; text-align: left;"><span style="font-weight: bold;">Money
Market Fund Risk: </span>Money market funds are sometimes unable to maintain an NAV at $1.00 per share and, as it is generally referred
to, “break the buck”. In that event, an investor in a money market fund would, upon redemption, receive less than $1.00 per
share. The Portfolio’s shareholders should not rely on or expect an affiliate of the Portfolio to purchase distressed assets from
the Portfolio, make capital infusions, enter into credit support agreements or take other actions to prevent the Portfolio from breaking
the buck. In addition, you should be aware that significant redemptions by large investors in the Portfolio could have a material adverse
effect on the Portfolio’s other shareholders. The Portfolio’s NAV could be affected by forced selling during periods of high
redemption pressures and/or illiquid markets. Money market funds are also subject to regulatory risk.</div> </td> </tr>
</table>
<div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 2%; font-size: 10pt; font-family: times new roman;">On July 12, 2023,
the SEC adopted amendments to Rule 2a-7 (“Money Market Fund Reforms”) that, among other things, removed the provisions in
Rule 2a-7 that permitted a money market fund to suspend redemptions. The Money Market Fund Reforms also removed the link between liquidity
fees and impaired liquidity of the Portfolio’s investments, permitting a government money market fund, such as the Portfolio, to
impose a discretionary liquidity fee if the fund’s board of directors determines that a liquidity fee is in the best interests of
the fund. These changes under the Money Market Fund Reforms became effective on October 2, 2023. The Portfolio’s Board of Directors
previously determined not to impose liquidity fees on, or suspend, redemptions.</div>
<div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 2%; font-size: 10pt; font-family: times new roman;">The Portfolio’s
yield will change based on changes in interest rates and other market conditions. Global economies and financial markets are increasingly
interconnected, which increases the probabilities that conditions in one country or region might adversely impact issuers in a different
country or region. Conditions affecting the general economy, including interest rate levels, tariffs and political, social, or economic
instability at the local, regional, or global level may also affect the market value of a security. Health crises, such as pandemic and
epidemic diseases, as well as other incidents that interrupt the expected course of</div>
<div style="margin-top: 0pt; margin-bottom: 0pt; margin-left: 2%; font-size: 10pt; font-family: times new roman;">events, such as natural
disasters, including fires, earthquakes and flooding, war or civil disturbance, acts of terrorism, supply chain disruptions, power outages
and other unforeseeable and external events, and the public response to or fear of such diseases or events, have had, and may in the future
have, an adverse effect on the Portfolio’s investments and net asset value and can lead to increased market volatility. The
occurrence and pendency of such crises or incidents could adversely affect the economies and financial markets either in specific countries
or worldwide. Rates of inflation have recently risen. The value of assets or income from an investment may be worth less in the future
as inflation decreases the value of money. As inflation increases, the real value of the Portfolio’s assets may decline.</div>

<div style="margin-top: 0pt; margin-bottom: 0pt; font-family: times new roman; font-size: 10pt; text-align: left;"><span style="font-weight: bold;">Interest
Rate Risk:</span> Changing interest rates, including rates that fall below zero, affect the yield and value of the Portfolio’s investments
in short-term debt securities, may have unforeseeable effects on markets and market volatility and may have an adverse effect on Portfolio
performance. Generally, an increase in interest rates causes the value of a debt instrument to decrease. The change in value for shorter-term
securities is usually smaller than for securities with longer maturities. A decline in interest rates affects the Portfolio’s yield
as portfolio securities mature or are sold and the Portfolio purchases new short-term securities with lower yields. During periods of
very low or negative interest rates, the Portfolio may be unable to maintain a positive yield or a stable NAV at $1.00.</div> </td> </tr>

Risk:</span> Credit risk is the possibility that a security’s credit rating will be downgraded or that the issuer of the security
will default (fail to make scheduled interest or principal payments). If a counterparty to a repurchase agreement defaults on its repurchase
obligation, the Portfolio might suffer a loss to the extent that the proceeds from the sale of the collateral were less than the repurchase
price. If the counterparty became bankrupt, the Portfolio might be delayed in selling the collateral. The Portfolio’s investments
in U.S. Government securities or related repurchase agreements have minimal credit risk compared to other investments.</div> </td> </tr>

Risk:</span> The Portfolio is subject to management risk because it is an actively-managed investment fund. The Adviser will apply its
investment techniques and risk analyses in making investment decisions for the Portfolio, but there is no guarantee that its techniques
will produce the intended results. Some of these techniques may incorporate, or rely upon, quantitative models, but there is no guarantee
that these models will generate accurate forecasts, reduce risk or otherwise perform as expected.</div> </td> </tr>

You
could lose money by investing in the Portfolio.
Although
the Portfolio seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so.
An
investment in the Portfolio is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any
other government agency.
The
Portfolio’s sponsor is not required to reimburse the Portfolio for losses, and you should not expect that the sponsor will provide
financial support to the Portfolio at any time, including during periods of market stress.

Portfolio’s past performance, of course, does not necessarily indicate how it will perform in the future. The Portfolio
adopted a multiple-class plan effective June 1, 2016. Upon the adoption of the multiple-class plan by the Portfolio, the original
share class of the Portfolio (“original share class”) was renamed Class AB shares. Accordingly, the performance information
presented below for the Class AB shares for the period prior to June 1, 2016 is the performance information of the original
share class that existed prior to such date. An advisory fee for the Portfolio was implemented effective June 1, 2016 and prior to
that time the Portfolio did not pay an advisory fee. Accordingly, historical performance information for the period prior to June 1,
2016 does not reflect the Portfolio’s payment of an advisory fee. If such fee had been in place, investment performance for
that period would have been lower than what is indicated below.</div>

A sales charge of up to
4.25% may be imposed upon an exchange of Class A shares for the Class A shares of other AB Mutual Funds with sales charges.
See Investing in the Portfolio—The Different Share Class Expenses—Sales Charges—Class A Shares on page 11
of this Prospectus.
Amount is equal to less
than 0.005%.
Purchases
of Class A shares in amounts of $1,000,000
or more, or by certain group retirement plans, may be subject to a 1%, 1-year contingent deferred sales charge, or CDSC, which may be
subject to waiver in certain circumstances.
The Total Annual Portfolio
Operating Expenses will not correlate to the Portfolio’s ratio to average net assets of expenses, net of waivers/reimbursements,
included in the Portfolio’s Financial Highlights, which reflect voluntary expense reimbursements made by the Adviser to the Portfolio.
With respect to Class A and Class C shares, the Adviser and its affiliates have agreed to waive receipt of 12b-1 fees. Such voluntary
waivers/reimbursements may be discontinued at any time.
For
Class C shares, the CDSC is 0% after the first year. Class C shares automatically convert to Class A shares after eight
years.
If you did not redeem your
shares at the end of the period, your expenses would be decreased by approximately $100.
Inception dates: June 1,
2016 for Institutional Class shares and November 10,
2017 for Class A, Class C, Advisor Class, Class I
and Class 1 shares. Performance information for periods prior to the inception of Class A, Class C, Advisor Class, Class I,
Class 1 and Institutional Class shares is the performance of Class AB shares adjusted to reflect the respective expenses
of the Class A, Class C, Advisor Class, Class I, Class 1 and Institutional Class shares.
