| Principal Risks |
An
investment in the fund is not a bank account or a bank deposit. It is not insured or guaranteed by the
Federal Deposit Insurance Corporation (FDIC) or any other government agency. 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. The fund's yield will fluctuate as the short-term securities
in its portfolio mature or are sold and the proceeds are reinvested in securities with different interest
rates. BNY Mellon Investment Adviser, Inc. and its affiliates are not required to reimburse the fund
for losses, and you should not expect that BNY Mellon Investment Adviser, Inc. or its affiliates will
provide financial support to the fund at any time, including during periods of market stress. The fund
is subject to the following principal risks:

| Risk Money Market Fund Price Fluctuates [Member] |
The fund's yield will fluctuate as the short-term securities

|
| Risk Money Market Fund May Not Preserve Dollar [Member] |
Although the fund seeks to preserve the value of your investment at $1.00 per
share, it cannot guarantee it will do so.
|
| Risk Not Insured [Member] |
An
investment in the fund is not a bank account or a bank deposit. It is not insured or guaranteed by the
Federal Deposit Insurance Corporation (FDIC) or any other government agency.
|
| · Interest rate risk |
· Interest rate risk: This
risk refers to the decline in the prices of fixed-income securities that may accompany a rise in the
overall level of interest rates. A sharp and unexpected rise in interest rates could impair the fund's
ability to maintain a stable net asset value. A wide variety of market factors
can cause interest rates to rise, including central bank monetary policy, rising inflation and changes
in general economic conditions. It is difficult to predict the pace at which central banks or monetary
authorities may increase (or decrease) interest rates or the timing, frequency, or magnitude of such
changes. Changing interest rates may have unpredictable effects on markets, may
result in heightened market volatility and may detract from fund performance. For floating and variable
rate obligations, there may be a lag between an actual change in the underlying interest rate benchmark
and the reset time for an interest payment of such an obligation, which could harm or benefit the fund,
depending on the interest rate environment or other circumstances.
|
| · Liquidity risk |
· Liquidity
risk: When there is little or no active trading market
for specific types of securities, it can become more difficult to sell the securities in a timely manner
at or near their perceived value. In such a market, the value of such securities may fall dramatically,
potentially impairing the fund's ability to maintain a stable net asset value.
|
| · U.S. Treasury securities risk |
· U.S.
Treasury securities risk: A security backed by the U.S. Treasury or
the full faith and credit of the United States is guaranteed only as to the timely payment of interest
and principal when held to maturity, but the market prices for such securities are not guaranteed and
will fluctuate.
|
| · Government securities risk |
· Government securities risk: Not
all obligations of the U.S. government, its agencies and instrumentalities are backed by the full faith
and credit of the U.S. Treasury. 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. Any guarantee
by the U.S. government or its agencies or instrumentalities of a security held by the fund does not apply
to the market value of such security or to shares of the fund itself.
|
| · Repurchase agreement counterparty risk |
· Repurchase
agreement counterparty risk: The fund is subject to the risk that a counterparty
in a repurchase agreement could fail to honor the terms of the agreement. If this occurs, the fund may
suffer a loss if the proceeds from the sale of the underlying securities are less than the repurchase
price.
|
| · Market risk |
· Market
risk: The value of the securities in which the fund invests may be affected by political,
regulatory, economic and social developments. In addition, turbulence in financial markets and reduced
liquidity in fixed-income markets may negatively affect many issuers, which could adversely affect the
fund. Global economies and financial markets are becoming increasingly interconnected, and conditions
and events in one country, region or financial market may adversely impact issuers in a different country,
region or financial market. These risks may be magnified if certain events or developments adversely
interrupt the global supply chain; in these and other circumstances, such risks might affect companies
world-wide. Local, regional or global events such as war, acts of terrorism, natural disasters, the
spread of infectious illness or other public health issues, recessions, elevated levels of government
debt, changes in trade regulation or economic sanctions, internal unrest and discord, or other events
could have a significant impact on the fund and its investments.

result in heightened market volatility and may detract from fund performance. For floating and variable
rate obligations, there may be a lag between an actual change in the underlying interest rate benchmark
and the reset time for an interest payment of such an obligation, which could harm or benefit the fund,
depending on the interest rate environment or other circumstances.

| · Liquidity risk |
· Liquidity
risk: When there is little or no active trading market
for specific types of securities, it can become more difficult to sell the securities in a timely manner
at or near their perceived value. In such a market, the value of such securities may fall dramatically,
potentially impairing the fund's ability to maintain a stable net asset value.
|
| · U.S. Treasury securities risk |
· U.S.
Treasury securities risk: A security backed by the U.S. Treasury or
the full faith and credit of the United States is guaranteed only as to the timely payment of interest
and principal when held to maturity, but the market prices for such securities are not guaranteed and
will fluctuate.
|
| · Government securities risk |
· Government securities risk: Not
all obligations of the U.S. government, its agencies and instrumentalities are backed by the full faith
and credit of the U.S. Treasury. 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. Any guarantee
by the U.S. government or its agencies or instrumentalities of a security held by the fund does not apply
to the market value of such security or to shares of the fund itself.
|
| · Market risk |
· Market
risk: The value of the securities in which the fund invests may be affected by political,
regulatory, economic and social developments. In addition, turbulence in financial markets and reduced
liquidity in fixed-income markets may negatively affect many issuers, which could adversely affect the
fund. Global economies and financial markets are becoming increasingly interconnected, and conditions
and events in one country, region or financial market may adversely impact issuers in a different country,
region or financial market. These risks may be magnified if certain events or developments adversely
interrupt the global supply chain; in these and other circumstances, such risks might affect companies
world-wide. Local, regional or global events such as war, acts of terrorism, natural disasters, the
spread of infectious illness or other public health issues, recessions, elevated levels of government
debt, changes in trade regulation or economic sanctions, internal unrest and discord, or other events
could have a significant impact on the fund and its investments.

or any other government agency. 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. The
fund's yield will fluctuate as the short-term securities in its portfolio mature or are sold and the
proceeds are reinvested in securities with different interest rates. BNY Mellon Investment Adviser,
Inc. and its affiliates are not required to reimburse the fund for losses, and you should not expect
that BNY Mellon Investment Adviser, Inc. or its affiliates will provide financial support to the fund
at any time, including during periods of market stress. The fund is subject to the following principal
risks:

· Interest
rate risk: This risk refers to the decline in the prices of fixed-income
securities that may accompany a rise in the overall level of interest rates. A sharp and unexpected
rise in interest rates could impair the fund's ability to maintain a stable net asset
value. A wide variety of market factors can cause interest rates to rise, including central bank monetary
policy, rising inflation and changes in general economic conditions. It is difficult to predict the
pace at which central banks or monetary authorities may increase (or decrease) interest rates or the
timing, frequency, or magnitude of such changes. Changing interest rates may have unpredictable effects
on markets, may result in heightened market volatility and may detract
from fund performance. For floating and variable rate obligations, there may be a lag between an actual

agreement counterparty risk: The fund is subject to the risk that a counterparty
in a repurchase agreement could fail to honor the terms of the agreement. If this occurs, the fund may
suffer a loss if the proceeds from the sale of the underlying securities are less than the repurchase
price.

| · Interest rate risk |
· Interest rate risk: This
risk refers to the decline in the prices of fixed-income securities that may accompany a rise in the
overall level of interest rates. A sharp and unexpected rise in interest rates could impair the fund's
ability to maintain a stable net asset value. A wide variety of market factors
can cause interest rates to rise, including central bank monetary policy, rising inflation and changes
in general economic conditions. It is difficult to predict the pace at which central banks or monetary
authorities may increase (or decrease) interest rates or the timing, frequency, or magnitude of such
changes. Changing interest rates may have unpredictable effects on markets, may
result in heightened market volatility and may detract from fund performance. For floating and variable
rate obligations, there may be a lag between an actual change in the underlying interest rate benchmark
and the reset time for an interest payment of such an obligation, which could harm or benefit the fund,
depending on the interest rate environment or other circumstances.
|
| · Liquidity risk |
· Liquidity
risk: When there is little or no active trading market
for specific types of securities, it can become more difficult to sell the securities in a timely manner
at or near their perceived value. In such a market, the value of such securities may fall dramatically,
potentially impairing the fund's ability to maintain a stable net asset value.
|
| · U.S. Treasury securities risk |
· U.S.
Treasury securities risk: A security backed by the U.S. Treasury or
the full faith and credit of the United States is guaranteed only as to the timely payment of interest
and principal when held to maturity, but the market prices for such securities are not guaranteed and
will fluctuate.
|
| · Government securities risk |
· Government securities risk: Not
all obligations of the U.S. government, its agencies and instrumentalities are backed by the full faith
and credit of the U.S. Treasury. 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. Any guarantee
by the U.S. government or its agencies or instrumentalities of a security held by the fund does not apply
to the market value of such security or to shares of the fund itself.
|
| · Repurchase agreement counterparty risk |
· Repurchase
agreement counterparty risk: The fund is subject to the risk that a counterparty
in a repurchase agreement could fail to honor the terms of the agreement. If this occurs, the fund may
suffer a loss if the proceeds from the sale of the underlying securities are less than the repurchase
price.
|
| · Market risk |
· Market
risk: The value of the securities in which the fund invests may be affected by political,
regulatory, economic and social developments. . In addition, turbulence in financial markets and reduced
liquidity in fixed-income markets may negatively affect many issuers, which could adversely affect the
fund. Global economies and financial markets are becoming increasingly interconnected, and conditions
and events in one country, region or financial market may adversely impact issuers in a different country,
region or financial market. These risks may be magnified if certain events or developments adversely
interrupt the global supply chain; in these and other circumstances, such risks might affect companies
world-wide. Local, regional or global events such as war, military conflicts, acts of terrorism, natural
disasters, the spread of infectious illness or other public health issues, recessions, elevated levels
of government debt,
changes in trade regulation or economic
sanctions, internal unrest and discord, or other events could have a significant impact on the fund and
its investments.
