your investment has a 5% return each year and that the fund's operating expenses remain the same.  Although

affiliates that invest primarily in equity securities issued by small cap companies.  The fund is designed

portion of the fund's assets allocated to the Small Cap Value Strategy normally is invested primarily
in equity securities of small cap value companies.  In constructing this portion of the fund's portfolio,
NIMNA employs a value-based investment style, which means that it seeks to identify those companies with
stocks trading at prices below what are believed to be their intrinsic value.  NIMNA focuses primarily
on individual stock selection for the Small Cap Value Strategy instead of trying to predict which industries
or sectors will perform best.  The stock selection process is designed to produce a diversified portfolio
of companies that the sub-adviser believes are undervalued relative to expected business growth, with
the presence of a catalyst (such as a corporate restructuring, change in management or spin-off) that
will trigger a near-term or mid-term price increase.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:10.0pt; font-family:Serif; font-style:normal; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;The portion
of the fund's assets allocated to the Small Cap Growth Strategy normally is invested primarily in equity
securities of small cap companies with favorable growth prospects.  In constructing this portion of the
fund's portfolio, NIMNA employs a growth-oriented investment style, which means it seeks to identify
those small cap companies which are experiencing or are expected to experience rapid earnings or revenue
growth.  NIMNA looks for high quality companies for the Small Cap Growth Strategy, especially those with
products or services that are believed to be leaders in their market niches.  NIMNA focuses on individual
stock selection instead of trying to predict which industries or sectors will perform best.  &lt;/p&gt;</oef:StrategyNarrativeTextBlock>

 Small and midsize companies carry additional risks because the operating histories of these companies
tend to be more limited, their earnings and revenues less predictable (and some companies may be experiencing
significant losses), and their share prices more volatile than those of larger, more established companies.
 The shares of smaller companies tend to trade less frequently than those of larger, more established
companies, which can adversely affect the pricing of these securities and the fund's ability to sell
these securities.  &lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

investing in a mix of growth and value companies, the fund assumes the risks of both.  Investors often
expect growth companies to increase their earnings at a certain rate.  If these expectations are not
met, investors can punish the stocks inordinately, even if earnings do increase.  Value stocks involve
the risk that they may never reach their expected full market value, either because the market fails
to recognize the stock's intrinsic worth or the expected value was misgauged.  &lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

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,

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 fee waiver agreement by BNY Mellon Investment

higher transaction costs and may result in higher taxes when fund shares are held in a taxable account.
 These costs, which are not reflected in annual fund operating expenses or in the Example, affect the

fund ordinarily will invest in a broad range of (and in any case at least five different) countries.
 The fund may, from time to time, invest a significant portion (more than 20%) of its total assets in
securities of issuers in a single country.  The fund will limit its investments in any single company
to no more than 5% of the fund's net assets at the time of purchase.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:10.0pt; font-family:Serif; font-style:normal; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;The stocks
purchased may have value and/or growth characteristics.  The fund's sub-adviser, Newton Investment Management
North America, LLC (NIMNA), an affiliate of BNY Mellon Investment Adviser, Inc. (BNYIA), employs a bottom-up
investment approach which emphasizes individual stock selection.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:10.0pt; font-family:Serif; font-style:normal; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;The stock
selection process is designed to produce a diversified portfolio that, relative to the Morgan Stanley
Capital International (MSCI) Europe, Australasia and Far East (EAFE) Index, has a below-average price/earnings
ratio and an above-average earnings growth trend.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:10.0pt; font-family:Serif; font-style:normal; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;The fund typically sells a
stock when, in the view of the fund's sub-adviser, it appears less likely to benefit from the current
market and economic environment, shows deteriorating fundamentals or declining momentum, or falls short
of the expectations of the fund's sub-adviser.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

 Small and midsize companies carry additional risks because the operating histories of these companies
tend to be more limited, their earnings and revenues less predictable (and some companies may be experiencing
significant losses), and their share prices more volatile than those of larger, more established companies.
 The shares of smaller companies tend to trade less frequently than those of larger, more established
companies, which can adversely affect the pricing of these securities and the fund's ability to sell
these securities.  &lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

investing in a mix of growth and value companies, the fund assumes the risks of both.  Investors often
expect growth companies to increase their earnings at a certain rate.  If these expectations are not
met, investors can punish the stocks inordinately, even if earnings do increase.  Value stocks involve
the risk that they may never reach their expected full market value, either because the market fails

invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities
of companies organized, or with a majority of assets or operations, in countries considered to be emerging
&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:10.0pt; font-family:Serif; font-style:normal; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;markets.  Emerging market countries generally include all countries represented
by the Morgan Stanley Capital International (MSCI) Emerging Markets Index.  The fund's portfolio allocations,
sector weightings and risk characteristics are a result of bottom-up fundamental analysis and may vary
from those of the MSCI Emerging Markets Index at any given time.  Normally, the fund will invest in companies
in a broad range of (and in any case at least five different) emerging market countries and may invest
in companies of any market capitalization.  The stocks purchased for the fund may have value and/or growth
characteristics.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:10.0pt; font-family:Serif; font-style:normal; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;The fund's sub-adviser, Newton Investment Management
Limited (NIM), an affiliate of BNY Mellon Investment Adviser, Inc. (BNYIA), employs a bottom-up investment
approach which emphasizes individual stock selection.  In selecting stocks for the fund's portfolio,
the fund's sub-adviser considers the qualitative and quantitative attributes of companies within the
emerging markets investment universe, including governance standards, long term growth outlook, business
franchise quality, pricing power, returns on invested capital and financial leverage.  The stock selection
process is designed to produce a diversified portfolio of equity securities perceived by the fund's sub-adviser
to have attractive quality and growth characteristics and priced at a level that offers an attractive
risk-reward profile for investors.  The fund may overweight or underweight certain emerging market countries,
companies, industries or market sectors relative to the MSCI Emerging Markets Index.  In addition, the
fund may, from time to time, invest a significant portion (more than 20%) of its total assets in securities
of companies in certain sectors or located in particular emerging market countries.  As of the date of
this prospectus, the fund expects to have significant exposure to securities of companies in China, India,
South Korea and Taiwan and to securities of companies in the information technology sector.   &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:10.0pt; font-family:Serif; font-style:normal; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;The fund typically sells a stock when the fund's sub-adviser determines the attributes
of the business have fundamentally deteriorated relative to their previously held view, or when developments
(including stock price moves) have caused the risk-reward profile of the investment to have fundamentally
deteriorated.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

investing in a mix of growth and value companies, the fund assumes the risks of both.  Investors often
expect growth companies to increase their earnings at a certain rate.  If these expectations are not
met, investors can punish the stocks inordinately, even if earnings do increase.  Value stocks involve
the risk that they may never reach their expected full market value, either because the market fails

risk:  &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;Investments in China are subject to the risks associated with greater governmental
control over the economy, political and legal uncertainties and currency fluctuations or blockage.  In
particular, the Chinese Communist Party exercises significant control over economic growth in China through
the allocation of resources, controlling payment of foreign currency-denominated obligations, setting
monetary policy and providing preferential treatment to particular industries or companies.  Attempts
by the government of the People's Republic of China to exert greater control over Hong Kong's economic,
political and legal structures or its existing social policy, could negatively affect investor confidence
in Hong Kong, which in turn could negatively affect markets and business performance of issuers located
in Hong Kong.  The Chinese economy and markets may be adversely affected by protectionist trade policies,
slow economic activity in other Asian countries or worldwide, political and social instability, environmental
events and natural disasters, regional and global conflicts, terrorism and war, including actions that
are contrary to the interests of the United States.  China's economy may be dependent on the economies
of other Asian countries, many of which are developing countries.  In addition, the imposition of tariffs
or other trade barriers by the U.S. or other foreign governments on exports from China may have an adverse
impact on Chinese issuers and China's economy as a whole.  Additionally, U.S. executive orders currently
prohibit U.S. persons, including the fund, from transacting in securities of any Chinese company identified
as a "Communist Chinese military company" or determined to be involved with China's "surveillance technology
sector," including transactions in instruments that are derivative of, or are designed to provide investment
exposure to, prohibited securities of such companies.  It is unclear how long the executive orders will
continue in effect, but to the extent that they do and further companies are designated, there may be
a material adverse impact on the value of those securities.&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Serif; font-style:italic; color:#000000; font-weight:normal; text-decoration:none;"&gt;India risk:  &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;Investments
in Indian issuers involve risks that are specific to India, including exposure to currency fluctuations,
less liquidity, expropriation, confiscatory taxation, and exchange control regulations (including currency
blockage).  The securities markets in India are relatively underdeveloped and may subject the fund to
higher transaction costs or greater uncertainty than investments in more developed securities markets.
 Further, the fund's investments are subject to fluctuations in the value of the Indian rupee.  Inflation
and rapid fluctuations in inflation and interest rates have had, and may continue to have, negative effects
on the economy and securities markets of India.  A high proportion of the securities of many Indian issuers
are held by a limited number of persons or entities, which may limit the number of shares available for
investment by the fund.  Also, a limited number of issuers represent a disproportionately large percentage
of market capitalization and trading value.  In addition, religious and border disputes persist in India.
 India has historically experienced hostilities with neighboring countries, such as Pakistan and China,
and the Indian government has confronted separatist movements in several Indian states.  Instability
as a result of these social and political tensions could adversely impact the value of the fund's investments
in India.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

volatile sectors of the stock market.  To the extent the fund's investments are significantly exposed
to companies in the information technology sector, the fund's performance will be significantly affected
by developments in that sector.  Information technology companies involve greater risk because their
revenue and/or earnings tend to be less predictable (and some companies may be experiencing significant
losses) and their share prices tend to be more volatile.  Certain information technology companies may
have limited product lines, markets or financial resources, or may depend on a limited management group.
 Technology companies are heavily dependent on patent and other intellectual property rights.  In addition,
these companies are strongly affected by worldwide technological developments, government regulation,
and increased competition, and their products and services may not be economically successful or may
quickly become outdated.  Investor perception may play a greater role in determining the day-to-day value
of information technology stocks than it does in other sectors.  Fund investments may decline dramatically
in value if anticipated products or services are delayed or cancelled.  &lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

emphasizes small-, mid- or large-cap stocks, it will assume the associated risks.  At any given time,
any of these market capitalizations may be out of favor with investors.  Compared to small- and mid-cap
companies, large-cap companies may be less responsive to changes and opportunities affecting their business.
 To the extent the fund invests in small- and mid-cap companies, it will be subject to additional risks
because the operating histories of these companies tend to be more limited, their earnings and revenues
less predictable (and some companies may be experiencing significant losses), and their share prices
more volatile than those of larger, more established companies.  The shares of smaller companies tend
to trade less frequently than those of larger, more established companies, which can adversely affect
the pricing of these securities and the fund's ability to sell these securities.  &lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

at or near their perceived value.  In such a market, the value of such securities and the fund's share
price may fall dramatically.  Investments that are illiquid or that trade in lower volumes may be more
difficult to value.  Investments in foreign securities, particularly those of issuers located in emerging

normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in bonds.
 The fund's sub-adviser, Insight North America LLC (INA), an affiliate of BNY Mellon Investment Adviser,
Inc. (BNYIA), actively manages the fund's bond market and maturity exposure and credit profile and uses
a disciplined process to select bonds and manage risk.  The process includes computer modeling and scenario
testing of possible changes in market conditions.  The fund's sub-adviser will use other techniques in
an attempt to manage market risk and duration.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:10.0pt; font-family:Serif; font-style:normal; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;The fund's investments in
bonds must be rated investment grade (i.e., Baa/BBB or higher) at the time of purchase or, if unrated,
deemed of comparable quality by the fund's sub-adviser.  Investments in bonds may include government
securities, corporate bonds, mortgage-related securities and municipal securities.  Generally, the average
effective duration of the fund's portfolio will not exceed eight years.  Because of events affecting
the bond markets and interest &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:10.0pt; font-family:Serif; font-style:normal; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;rate changes, the duration of the portfolio might not meet the foregoing target
at all times.  The fund may invest in individual bonds of any duration.  There are no restrictions on
the dollar-weighted average maturity of the fund's portfolio or on the maturities of the individual bonds
the fund may purchase.  A bond's maturity is the length of time until the principal must be fully repaid
with interest.  Dollar-weighted average maturity is an average of the stated maturities of the securities
held by the fund, based on their dollar-weighted proportions in the fund.  Duration is an indication
of an investment's "interest rate risk," or how sensitive a bond or the fund's portfolio may be to changes
in interest rates.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:10.0pt; font-family:Serif; font-style:normal; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;The fund may use derivative instruments as
a substitute for investing directly in an underlying asset, to increase returns, to manage interest rate
risk, to manage the effective duration or maturity of the fund's portfolio, or as part of a hedging strategy.
 The derivative instruments in which the fund may invest typically include options, futures and options
on futures (including those relating to securities, indices and interest rates).&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:10.0pt; font-family:Serif; font-style:normal; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;The
fund typically sells a security when the fund's sub-adviser believes that there has been a negative change
in the credit quality of the issuer or has identified a more attractive opportunity or when the sub-adviser
seeks to manage the fund's duration or tax position or to provide liquidity to meet shareholder redemptions.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

value of a fixed-income security may decline due to general market conditions that are not specifically
related to a particular company, such as real or perceived adverse economic conditions, changes in the
outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally.
 The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity.
 Liquidity can decline unpredictably in response to overall economic conditions or credit tightening.
 Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the
expectation of a rise in interest rates).  An unexpected increase in fund redemption requests, including
requests from shareholders who may own a significant percentage of the fund's shares, which may be triggered
by market turmoil or an increase in interest rates, could cause the fund to sell its holdings at a loss
or at undesirable prices and adversely affect the fund's share price and increase the fund's liquidity
risk, fund expenses and/or taxable distributions.  Federal Reserve policy in response to market conditions,
including with respect to interest rates, may adversely affect the value, volatility and liquidity of
dividend and interest paying securities.  Policy and legislative changes worldwide are affecting many
aspects of financial regulation.  The impact of these changes on the markets and the practical implications
for market participants may not be fully known for some time.  &lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

of bonds and other fixed rate fixed-income securities tend to move inversely with changes in interest
rates.  Typically, a rise in rates will adversely affect fixed-income securities and, accordingly, will
cause the value of the fund's investments in these securities to decline.  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.  During periods of very low interest rates, which occur from time to time due to market forces
or actions of governments and/or their central banks, including the Board of Governors of the Federal
Reserve System in the U.S., the fund may be subject to a greater risk of principal decline from rising
interest rates.  When interest rates fall, the fund's investments in new securities may be at lower yields
and may reduce the fund's income.  Changing interest rates may have unpredictable effects on markets,
may result in heightened market volatility and may detract from fund performance.  The magnitude of these
fluctuations in the market price of fixed-income securities is generally greater for securities with
longer effective maturities and durations because such instruments do not mature, reset interest rates
or become callable for longer periods of time.  &lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

securities give the issuer the option to prepay or call the securities before their maturity date, which
may reduce the market value of the security and the anticipated yield-to-maturity.  Issuers often exercise
this right when interest rates fall.  If an issuer "calls" its securities during a time of declining
interest rates, the fund might have to reinvest the proceeds in an investment offering a lower yield,
and therefore might not benefit from any &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:10.0pt; font-family:Serif; font-style:normal; text-align:justify; color:#000000; font-weight:normal; margin-left:8.65pt; text-decoration:none;"&gt;increase in value as a result of declining

 Mortgage-related securities are subject to credit, prepayment and extension risk, and may be more volatile,
less liquid and more difficult to price accurately than more traditional debt securities.  The fund is
subject to the credit risk associated with these securities, including the market's perception of the
creditworthiness of the issuing federal agency, as well as the credit quality of the underlying assets.
 Although certain mortgage-related securities are guaranteed as to the timely payment of interest and
principal by a third party (such as a U.S. government agency or instrumentality with respect to government-related
mortgage securities) the market prices for such securities are not guaranteed and will fluctuate.  As
with other interest-bearing securities, the prices of certain mortgage-related securities are inversely
affected by changes in interest rates.  However, although the value of a mortgage-related security may
decline when interest rates rise, the converse is not necessarily true, since in periods of declining
interest rates the mortgages underlying the security are more likely to be prepaid causing the fund to
purchase new securities at current market rates, which usually will be lower.  The loss of higher yielding
underlying mortgages and the reinvestment of proceeds at lower interest rates, known as prepayment risk,
can reduce the fund's potential price gain in response to falling interest rates, reduce the fund's yield
and/or cause the fund's share price to fall.  When interest rates rise, the effective duration of the
fund's mortgage-related and other asset-backed securities may lengthen due to a drop in prepayments of
the underlying mortgages or other assets.  This is known as extension risk and would increase the fund's
sensitivity to rising interest rates and its potential for price declines.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

liquidity, valuation, market and political risks.  The amount of public information available about municipal
securities is generally less than that for corporate equities or bonds.  Special factors, such as legislative
and regulatory changes, executive orders, voter initiatives, and state and local economic and business
developments, may adversely affect the value of the fund's investments in municipal securities.  Other
factors include the general conditions of the municipal securities market, the size of the particular
offering, the maturity of the obligation and the rating of the issue.  Changes in economic, business
or political conditions relating to a particular municipal project, municipality, or state, territory
or possession of the United States in which the fund invests may have an impact on the fund's share price.
 Any credit impairment could adversely impact the value of municipal bonds, which could negatively impact
the performance of the fund.  In addition, income from municipal securities held by the fund could be
declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations
by the Internal Revenue Service or state tax authorities, or noncompliant conduct of an issuer or other
obligated party.  Loss of tax-exempt status for municipal securities held by the fund may cause interest
received and distributed to shareholders by the fund to be taxable and may result in a significant decline
in the values of such municipal securities.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

an investment may differ from the fund's valuation of the investment, particularly for investments that
trade in lower volumes, investments that are valued using a fair valuation methodology or a price provided
by an independent pricing service, or during market turmoil or volatility.  As a result, the price received
upon the sale of an investment may be less than the value ascribed by the fund, and the fund could realize

risk&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;:  A small investment in derivatives could have a potentially large impact on
the fund's performance.  The use of derivatives involves risks different from, or possibly greater than,
the risks associated with investing directly in the underlying assets, and the fund's use of derivatives
may result in losses to the fund.  Derivatives in which the fund may invest can be highly volatile, illiquid
and difficult to value, and there is the risk that changes in the value of a derivative held by the fund
will not correlate with the underlying assets or the fund's other investments in the manner intended.
 Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment,
and involve greater risks than the underlying assets because, in addition to general market risks, they
are subject to liquidity risk, credit and counterparty risk (failure of the counterparty to the derivatives
transaction to honor its obligation) and pricing risk (risk that the derivative cannot or will not be
accurately valued).&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;  &lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in municipal
bonds that provide income exempt from federal and Massachusetts state personal income taxes.  These municipal
bonds include those issued by the Commonwealth of Massachusetts as well as those issued by territories
and possessions of the United States and the District of Columbia and their political subdivisions, agencies
and instrumentalities, or multistate agencies and authorities.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:10.0pt; font-family:Serif; font-style:normal; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;The fund's
investments in municipal and taxable bonds must be rated investment grade (i.e., Baa/BBB or higher) at
the time of purchase or, if unrated, deemed of comparable quality by the fund's sub-adviser, Insight
North America LLC (INA), an affiliate of BNY Mellon Investment Adviser, Inc. (BNYIA).  Generally, the
fund's average effective portfolio &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:10.0pt; font-family:Serif; font-style:normal; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;maturity will be between three and ten years and the average effective duration
of the fund's portfolio will not exceed eight years.  Because of events affecting the bond markets and
interest rate changes, the maturity and duration of the portfolio might not meet the foregoing targets
at all times.  The fund may invest in individual municipal and taxable bonds of any maturity or duration.
 A bond's maturity is the length of time until the principal must be fully repaid with interest.  Average
effective portfolio maturity is an average of the maturities of bonds held by the fund directly and the
bonds underlying derivative instruments entered into by the fund, if any, adjusted to reflect provisions
or market conditions that may cause a bond's principal to be repaid earlier than at its stated maturity.
 Duration is an indication of an investment's "interest rate risk," or how sensitive a bond or the fund's
portfolio may be to changes in interest rates.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:10.0pt; font-family:Serif; font-style:normal; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;Although the fund seeks to
provide income exempt from federal and Massachusetts state income taxes, income from some of the fund's
holdings may be subject to the federal alternative minimum tax.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:10.0pt; font-family:Serif; font-style:normal; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;The fund's
sub-adviser focuses on identifying undervalued sectors and securities.  To select municipal bonds for
the fund, the fund's sub-adviser uses fundamental credit analysis to estimate the relative value and
attractiveness of various sectors and securities and to exploit pricing inefficiencies in the municipal
bond market.  The fund's sub-adviser actively trades among various sectors and securities based on their
apparent relative values.  The fund seeks to invest in several different sectors and may overweight a
particular sector depending on each sector's relative value at a given time.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:10.0pt; font-family:Serif; font-style:normal; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;The
fund typically sells a security when the fund's sub-adviser believes that there has been a negative change
in the credit quality of the issuer or has identified a more attractive opportunity or when the sub-adviser
seeks to manage the fund's duration or tax position or to provide liquidity to meet shareholder redemptions.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

securities are subject to interest rate, credit, liquidity, valuation, market and political risks.  The
amount of public information available about municipal securities is generally less than that for corporate
equities or bonds.  Special factors, such as legislative and regulatory changes, executive orders, voter
initiatives, and state and local economic and business developments, may adversely affect the value of
the fund's investments in municipal securities.  Other factors include the general conditions of the
municipal securities market, the size of the particular offering, the maturity of the obligation and
the rating of the issue.  Changes in economic, business or political conditions relating to a particular
municipal project, municipality, or state, territory or possession of the United States in which the
fund invests may have an impact on the fund's share price.  Any credit impairment could adversely impact
the value of municipal bonds, which could negatively impact the performance of the fund.  In addition,
income from municipal securities held by the fund could be declared taxable because of, among other things,
unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax
authorities, or noncompliant conduct of an issuer or other obligated party.  Loss of tax-exempt status
for municipal securities held by the fund may cause interest received and distributed to shareholders
by the fund to be taxable and may result in a significant decline in the values of such municipal securities.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

tend to move inversely with changes in interest rates.  Typically, a rise in rates will adversely affect
fixed-income securities and, accordingly, will cause the value of the fund's investments in these securities
to decline.  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.  During periods of very low interest rates, which
occur from time to time due to market forces or actions of governments and/or their central banks, including
the Board of Governors of the Federal Reserve System in the U.S., the fund may be subject to a greater
risk of principal decline from rising interest rates.  When interest rates fall, the fund's investments
in new securities may be at lower yields and may reduce the fund's income.  Changing interest rates may
have unpredictable effects on markets, may result in heightened market volatility and may detract from
fund performance.  The magnitude of these fluctuations in the market price of fixed-income securities
is generally greater for securities with longer effective maturities and durations because such instruments
do not mature, reset interest rates or become callable for longer periods of time.  &lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

risk:&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;  Some securities give the issuer the option to prepay or call the securities
before their maturity date, which may reduce the market value of the security and the anticipated yield-to-maturity.
 Issuers often exercise this right when interest rates fall.  If an issuer "calls" its securities during
a time of declining interest rates, the fund might have to reinvest the proceeds in an investment offering
a lower yield, and therefore might not benefit from any increase in value as a result of declining interest
rates.  During periods of market illiquidity or rising interest rates, prices of "callable" issues are
subject to increased price fluctuation.  &lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

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;/p&gt;</oef:ExpenseExampleNarrativeTextBlock>

higher transaction costs and may result in higher taxes when fund shares are held in a taxable account.

funds, closed-end funds and exchange-traded funds (referred to below as the "underlying funds"), which

intends to allocate its assets, directly and/or through investment in the underlying funds, to gain investment
exposure to the following asset classes: Large Cap Equities, Small Cap and Mid Cap Equities, Developed
International and Global Equities, Emerging Markets Equities, Investment Grade Bonds, High Yield Bonds,

Mellon Investment Adviser, Inc. (BNYIA) allocates the fund's investments (directly and/or through investment
in the underlying funds) among these asset classes using fundamental and quantitative analysis, and its
outlook for the economy and financial markets.  BNYIA has engaged its affiliate, Insight North America
LLC (INA), to serve as a sub-adviser responsible for the portion of the fund's assets allocated to direct
investments in fixed-income securities.  The underlying funds are selected by BNYIA based on their investment
objectives and management policies, portfolio holdings, risk/reward profiles, historical performance,
and other factors, including the correlation and covariance among the underlying funds.  The fund may
change the underlying funds &#x2013; whether affiliated or unaffiliated &#x2013; from time to time without notice
to or approval by fund shareholders.  The fund may invest directly in the equity securities of large-cap
companies (generally those with total market capitalizations of $5 billion or more) and in fixed-income
securities rated investment grade (i.e., Baa/BBB or higher) or, if unrated, deemed to be of comparable
quality by INA, at the time of purchase.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:10.0pt; font-family:Serif; text-align:left; color:#000000; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:10.0pt; font-family:Serif; font-style:normal; color:#000000; font-weight:normal; text-decoration:none;"&gt;The fund is not required

classes and the target weightings and ranges have been selected for investment over longer time periods
based on BNYIA's expectation that the selected securities and underlying funds, in combination, will
be appropriate to achieve the fund's investment objective.  The target weightings will deviate over the
short term because of market movements and fund cash flows.  If appreciation or depreciation in the value
of selected securities or an underlying fund's shares causes the percentage of the fund's assets invested
in an asset class to fall outside the applicable investment range, BNYIA will consider whether to reallocate
the fund's assets, but is not required to do so.  BNYIA normally considers reallocating the fund's investments
at least quarterly, but may do so more often in response to market conditions.  Any changes to the asset
classes, underlying funds or the allocation weightings may be implemented over a reasonable period of
time.  BNYIA has the discretion to change the asset classes, whether to invest directly in securities
or through an underlying fund, and the target allocations and ranges, without shareholder approval or
prior notice, when BNYIA deems it appropriate.  To the extent an underlying fund offers multiple classes
of shares, the fund will purchase shares of the class with the lowest expense ratio and without a sales
load or distribution and/or service fee.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

the risk that they may never reach their expected full market value, either because the market fails

tend to trade less frequently than those of larger, more established companies, which can adversely affect

to general market conditions that are not specifically related to a particular company, such as real
or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest
or currency rates or adverse investor sentiment generally.  The fixed-income securities market can be
susceptible to increases in volatility and decreases in liquidity.  Liquidity can decline unpredictably
in response to overall economic conditions or credit tightening.  Increases in volatility and decreases
in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates).
 An unexpected increase in fund redemption requests, including requests from shareholders who may own
a significant percentage of the fund's shares, which may be triggered by market turmoil or an increase
in interest rates, could cause the fund to sell its holdings at a loss or at undesirable prices and adversely
affect the fund's share price and increase the fund's liquidity risk, fund expenses and/or taxable distributions.
 Federal Reserve policy in response to market conditions, including with respect to interest rates, may
adversely affect the value, volatility and liquidity of dividend and interest paying securities.  Policy
and legislative changes worldwide are affecting many aspects of financial regulation.  The impact of
these changes on the markets and the practical implications for market participants may not be fully
known for some time.  &lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

 Issuers often exercise this right when interest rates fall.  If an issuer "calls" its securities during
a time of declining interest rates, the fund might have to reinvest the proceeds in an investment offering
a lower yield, and therefore might not benefit from any increase in value as a result of declining interest
rates.  During periods of market illiquidity or rising interest rates, prices of "callable" issues are
subject to increased price fluctuation.  &lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

tend to move inversely with changes in interest rates.  Typically, a rise in rates will adversely affect
fixed-income securities and, accordingly, will cause the value of the fund's investments in these securities
to decline.  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.  During periods of very low interest rates, which
occur from time to time due to market forces or actions of governments and/or their central banks, including
the Board of Governors of the Federal Reserve System in the U.S., the fund may be subject to a greater
risk of principal decline from rising interest rates.  When interest rates fall, the fund's investments
in new securities may be at lower yields and may reduce the fund's income.  Changing interest rates may
have unpredictable effects on markets, may result in heightened market volatility and may detract from
fund performance.  The magnitude of these fluctuations in the market price of fixed-income securities
is generally greater for securities with longer effective maturities and durations because such instruments
do not mature, reset interest rates or become callable for longer periods of time.  &lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

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 and the fund's share price may fall dramatically.  The secondary market for certain
municipal bonds tends to be less well developed or liquid than many other securities markets, which may
adversely affect the fund's ability to buy or sell such municipal bonds at attractive prices.  Investments
that are illiquid or that trade in lower volumes may be more difficult to value.  The market for below
investment grade securities may be less liquid and therefore securities may be harder to value or buy
or sell at an acceptable price, especially during times of market volatility or decline.  Investments
in foreign securities, particularly those of issuers located in emerging markets, tend to have greater
exposure to liquidity risk than domestic securities.  No active trading market may exist for some of
the floating rate loans in which the fund invests and certain loans may be subject to restrictions on
resale.  Because some floating rate loans that the fund invests in may have a more limited secondary
market, liquidity risk is more pronounced for the fund than for mutual funds that invest primarily in
other types of fixed-income instruments or equity securities.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

 To the extent the fund invests in pooled investment vehicles, such as ETFs and other investment companies,
the fund will be affected by the investment policies, practices and performance of such entities in direct
proportion to the amount of assets the fund has invested therein.  The risks of investing in other investment
companies, including ETFs, typically reflect the risks associated with the types of instruments in which
the investment companies invest.  When the fund invests in an ETF or other investment company, shareholders
of the fund will bear indirectly their proportionate share of the expenses of the ETF or other investment
company (including management fees) in addition to the expenses of the fund.  ETFs are exchange-traded
investment companies that are, in many cases, designed to provide investment results corresponding to
an index.  The value of the underlying securities can fluctuate in response to activities of individual
companies or in response to general market and/or economic conditions.  Additional risks of investments
in ETFs include: (i) the market price of an ETF's shares may trade at a discount to its net asset value;
(ii) an active trading market for an ETF's shares may not develop or be maintained; or (iii) trading
may be halted if the listing exchanges' officials deem such action appropriate, the shares are delisted
from the exchange, or the activation of market-wide "circuit breakers" (which are tied to large decreases
in stock prices) halts trading generally.  The fund will incur brokerage costs when purchasing and selling
shares of ETFs.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

of the securities in which the fund invests may be affected by political, regulatory, economic and social
developments, and developments that impact specific economic sectors, industries or segments of the market.&#160;
In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed-income
markets may negatively affect many issuers, which could adversely affect the fund.&#160; 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.&#160;
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.&#160; 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.&#160; &lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>
