your investment has a 5% return each year, that the Fund&#x2019;s operating expenses stay the same and that any fee waiver and/or expense

&lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: times new roman;"&gt;The
Fund pursues opportunistic growth by investing in a global universe of companies whose business activities the Adviser believes position
the company to benefit from certain sustainable investment themes that align with one or more of the United Nations Sustainable Development
Goals (&#x201c;SDGs&#x201d;). These themes include the advancement of climate, health and empowerment. Under
normal circumstances, the Fund invests at least 80% of its net assets in equity securities of issuers located throughout the world that
satisfy the Fund&#x2019;s sustainability criteria. An issuer that derives at least 25% of its total revenues from activities
consistent with the achievement of the SDGs meets such criteria, although many of the issuers in which the Fund invests will derive a
much greater portion of their revenues from such activities.&lt;/div&gt; 

&lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: times new roman;"&gt;The Adviser employs a combination of
&#x201c;top&#x2011;down&#x201d; and &#x201c;bottom&#x2011;up&#x201d; investment processes with the goal of identifying, based on its internal
research and analysis, securities of companies worldwide, that fit into sustainable investment themes. First, under the &#x201c;top&#x2011;down&#x201d;
approach, the Adviser identifies the sustainable investment themes. In addition to this &#x201c;top&#x2011;down&#x201d; thematic approach,
the Adviser then uses a &#x201c;bottom&#x2011;up&#x201d; analysis of individual companies, focusing on prospective earnings growth, valuation,
and quality of company management and on evaluating a company&#x2019;s exposure to environmental, social and corporate governance (&#x201c;ESG&#x201d;)
factors. ESG factors, which can vary across companies and industries, may include environmental impact, corporate governance, ethical
business practices, employee practices, product safety, supply chain management and community impact. Eligible investments include securities
of issuers that the Adviser believes will maximize total return while also contributing to positive societal impact aligned with one or
more SDGs. While the Adviser emphasizes company-specific positive selection criteria over broad-based negative screens in assessing a
company&#x2019;s exposure to ESG factors, the Fund will not invest in companies that derive revenue from direct involvement in adult entertainment,
alcohol, cannabis, coal, controversial weapons, firearms, gambling, genetically modified organisms, military contracting, prisons, or
tobacco. Activities deriving revenue and revenue thresholds may vary by sector.&lt;/div&gt; 

&lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: times new roman;"&gt;The Adviser normally considers a large
universe of mid&#x2011; to large-capitalization companies worldwide for investment.&lt;/div&gt; 

&lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: times new roman;"&gt;The Fund invests in securities issued
by U.S. and non&#x2011;U.S. companies from multiple industry sectors in an attempt to maximize opportunity, which should also tend to reduce
risk. The Fund invests in both developed and emerging market countries. Under normal market conditions, the Fund invests significantly
(at least 40%&#x2014;unless market conditions are not deemed favorable by the Adviser) in securities of non&#x2011;U.S. companies. In addition,
the Fund invests, under normal circumstances, in the equity securities of companies located in at least three countries. The percentage
of the Fund&#x2019;s assets invested in securities of companies in a particular country or denominated in a particular currency varies
in accordance with the Adviser&#x2019;s assessment of the appreciation potential of such securities. The Fund may invest in any company
and industry and in any type of equity security, listed and unlisted, with potential for capital appreciation. It invests in well-known,
established companies as well as new, smaller or less-seasoned companies. Investments in new, smaller or less-seasoned companies may offer
more reward but may also entail more risk than is generally true of larger, established companies. The Fund may also invest in synthetic
foreign equity securities, which are various types of warrants used internationally that entitle a holder to buy or sell underlying securities,
real estate investment trusts (&#x201c;REITs&#x201d;) and zero&#x2011;coupon bonds.&lt;/div&gt; 

&lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: times new roman;"&gt;The Fund may, at times, invest in shares
of exchange-traded funds (&#x201c;ETFs&#x201d;) in lieu of making direct investments in securities. ETFs may provide more efficient and
economical exposure to the types of companies and geographic locations in which the Fund seeks to invest than direct investments. Investments
in ETFs will not be subject to the Fund&#x2019;s sustainable investment themes or ESG factors.&lt;/div&gt; 

&lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: times new roman;"&gt;Currencies can have a dramatic impact
on equity returns, significantly adding to returns in some years and greatly diminishing them in others. Currency and equity positions
are evaluated separately. The Adviser may seek to hedge the currency exposure resulting from securities positions when it finds the currency
exposure unattractive. To hedge all or a portion of its currency risk, the Fund, from time to time, invests in currency-related derivatives,
including forward currency exchange contracts, futures contracts, options on futures contracts, swaps and options. The Adviser may also
seek investment opportunities by taking long or short positions in currencies through the use of currency-related derivatives.&lt;/div&gt; 

&lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: times new roman;"&gt;The Fund may enter into other derivatives
transactions, such as options, futures contracts, forwards, and swaps. The Fund may use options strategies involving the purchase and/or
writing of various combinations of call and/or put options, including on individual securities and stock indices, futures contracts (including
futures contracts on individual securities and stock indices) or shares of ETFs. These transactions may be used, for example, in an effort
to earn extra income, to adjust exposure to individual securities or markets, or to protect all or a portion of the Fund&#x2019;s portfolio
from a decline in value, sometimes within certain ranges.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

        Risk:&lt;/span&gt; Applying ESG and sustainability criteria to the investment process may exclude securities of certain issuers and, therefore,
        the Fund may forgo some market opportunities available to funds that do not use ESG or sustainability criteria. Securities of companies
        with ESG practices may shift into and out of favor depending on market and economic conditions, and the Fund&#x2019;s performance may at
        times be better or worse than the performance of funds that do not use ESG or sustainability criteria. Furthermore, ESG and sustainability
        criteria are not uniformly defined, and the Fund&#x2019;s ESG and sustainability criteria may differ from those used by other funds. In
        addition, in evaluating an investment, the Adviser is dependent upon information and data that may be incomplete, inaccurate or unavailable,
        which could adversely affect the analysis of the ESG and sustainability factors relevant to a particular investment.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt;

        asset, reference rate or index, which could cause the Fund to suffer a potentially unlimited loss. Derivatives, especially over&#x2011;the&#x2011;counter

        to appreciation of portfolio securities that happened before you made your investment. Unless you purchase shares through a tax&#x2011;advantaged
        account (such as an IRA or 401(k) plan), these distributions will be taxable to you even though they economically represent a return of
        a portion of your investment. You should consult your tax professional about your investment in the Fund.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt;
