circumstances.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

of taxes or other restrictions on payment of principal and interest.  The imposition of sanctions, confiscations, 
trade restrictions (including tariffs) and other government restrictions by the United States and other 
governments, or from problems in share registration, settlement or custody, may also result in losses. 
 In addition, the fund will be subject to the risk that an issuer of foreign sovereign debt or the government 
authorities that control the repayment of the debt may be unable or unwilling to repay the principal

value of the securities in which the fund invests may be affected by political, regulatory, economic 
and social developments.&#160; 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.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

Example is intended to help you compare the cost of investing in the fund with the cost of investing 
in other mutual funds.  The Example assumes that you invest $10,000 in the fund for the time periods 
indicated and then hold or redeem all of your shares at the end of those periods.  The Example also assumes 
that your investment has a 5% return each year and that the fund's operating expenses remain the same. 
 The one-year example and the first year of the three-, five- and ten-years examples are based on net 
operating expenses, which reflect the expense limitation agreement by BNY Mellon Investment Adviser, 
Inc.  Although your actual costs may be higher or lower, based on these assumptions your costs would 
be:&lt;/span&gt;&lt;/p&gt;</oef:ExpenseExampleNarrativeTextBlock>

overall level of interest rates.  A sharp and unexpected rise in interest rates could impair the fund's

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&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Serif; font-style:normal; color:#000000; font-weight:normal; text-decoration:none;"&gt;, 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.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

value of the securities in which the fund invests may be affected by political, regulatory, economic 
and social developments.&#160; 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.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

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 &lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Serif; font-style:normal; color:#000000; font-weight:normal; text-decoration:none;"&gt;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&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Serif; font-style:normal; color:#000000; font-weight:normal; text-decoration:none;"&gt;, 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.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

of an issuer of a security to make timely interest or principal payments when due, or a decline or perception 
of a decline in the credit quality of the security, can cause the security's price to fall.  Although 
the fund invests only in high quality debt securities, the credit quality of the securities held by the 
fund can change rapidly in certain market environments, and the default or a significant price decline 
of a single holding could impair the fund's ability to maintain a stable net asset value.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>
