pursue its goal, the fund normally invests at least 80% of its net assets, plus any borrowings for investment 
purposes, in securities of power ecosystem companies.  The fund considers power ecosystem companies to 
be those companies that the fund's sub-adviser, Newton Investment Management North America, LLC (sub-adviser), 
determines should benefit from investment in, or growth of, the generation, transmission, distribution, 
storage, management, or efficient use of power, including equipment, services, materials, and enabling 
and/or emerging technologies related to power (collectively, power ecosystem themes).  In making this 
determination, the sub-adviser considers a company's business activities, products and technologies (including 
emerging products and technologies), services, assets, and/or current or expected sources of revenue, 
including as they relate to power generation and utilities; transmission, distribution, and grid infrastructure; 
power equipment, engineering, and infrastructure services; and energy transition, storage, and critical 
inputs, including renewable energy, battery storage, hydrogen, smart grid technologies, liquid cooling, 
rare earths, and nuclear-related activities.  &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; text-decoration:none;"&gt;The fund&#x2019;s investments 
are concentrated (i.e., more than 25% of its total assets) in power ecosystem-related industries.  The 
fund considers power ecosystem-related industries to be Construction &amp;amp; Engineering, Electrical Components 
&amp;amp; Equipment, Heavy Electrical Equipment, Electronic Equipment &amp;amp; Instruments, Trading Companies 
&amp;amp; Distributors, &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; text-decoration:none;"&gt;Industrial Gases, Diversified Metals &amp;amp; Mining, Electric

Industrial Conglomerates, Semiconductors, and Renewable Electricity (as such industries are defined by 
the Global Industry Classification Standard (&#x201c;GICS&#x201d;) or as may otherwise be defined by GICS in the 
future).    &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; text-decoration:none;"&gt;The fund invests principally in common stocks. 
 The fund may invest in stocks of companies of any market capitalization.  The fund may invest without 
limit in stocks of foreign companies, including companies located in emerging market countries.  Certain 
of the fund's investments may be denominated in foreign currencies.  The currency exposure of the fund's 
portfolio is generally unhedged to the U.S. dollar.  The fund may, from time to time, invest a significant 
portion (more than 20%) of its total assets in securities of companies located in a particular country 
or region.  As of the date of this Prospectus, in addition to the United States, the fund expects to 
invest a significant portion of its assets in securities of companies located in the European region.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert;font-size:10.0pt; font-family:Serif; text-align:justify; 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 
sub-adviser uses a proprietary investment process to select companies for the fund's portfolio.  This 
process  includes both quantitative and fundamental inputs to assess the degree of alignment to power 
ecosystem themes and to identify companies the sub-adviser believes will outperform the broader power 
ecosystem market.  The sub-adviser utilizes inputs such as company disclosures and earnings information 
as well as wider considerations in relation to competitive landscape and/or the regulatory environment. 
 &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;As part of its ongoing review of portfolio holdings, the sub-adviser may sell 
a security when it identifies that the original case for investment has weakened and/or the sub-adviser 
identifies a more compelling investment opportunity. &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; text-decoration:none;"&gt;The

companies, the fund is more susceptible to adverse economic, regulatory, political, legal and other developments 
affecting such companies.  Power ecosystem companies may experience substantial price volatility, carry 
relatively high levels of debt and be more likely than other companies to restructure their businesses 
and/or become unable to maintain capital construction programs during downturns in energy markets, broader 
economic slowdowns, or periods of high inflation and rising interest rates.  These companies are also 
subject to specific risks, including, among others, fluctuations in commodity prices and interest rates; 
changes in energy-related and environmental regulations (including energy conservation policies); government 
rate-setting standards (e.g., fixed rates charged to customers); changes in subsidy levels, tax laws, 
tariffs, and accounting standards; domestic and international political, regulatory, and economic conditions 
(especially in key energy&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Cambria Math; font-style:normal; color:#000000; font-weight:normal; text-decoration:none;"&gt;&#x2011;&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;producing and consuming 
countries); service interruptions or legal challenges arising from environmental, operational, or other 
incidents; constraints on the availability or cost of necessary resources; and shifts in market sentiment 
toward power ecosystem companies.  Power ecosystem companies also face operating risks, including the 
risk of fire, explosions, leaks, mining and drilling accidents and other catastrophic events.  In addition, 
natural disasters&#x2014;such as earthquakes, floods, lightning, hurricanes, tsunamis, and severe wind&#x2014;are 
inherent risks in these operations.  At times, securities of power ecosystem companies may underperform 
other industries or the broader market.  &lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

the fund concentrates its investments in power ecosystem-related industries, the fund may be subject 
to greater risks and market fluctuations than funds with broader industry exposure.  The fund is particularly 
susceptible to financial, economic, political, market, and regulatory events that impact power ecosystem-related 
industries.  The fund is subject to the risk that: (i) its performance will be closely tied to the performance 
of these industries; (ii) its performance will be adversely impacted when these industries experience 
a downturn; and (iii) it will perform poorly during periods of reduced investor demand for securities

generally fluctuate more in value than bonds and may decline significantly over short time periods.  
There is the chance that stock prices overall will decline because stock markets tend to move in cycles, 
with periods of rising prices and falling prices.  The market value of a stock may decline due to general 
market conditions or because of factors that affect the particular company or the company's industry. 
 Holders of common stock incur more risk than holders of preferred stock and debt obligations because 
common stockholders, as owners of the issuer, generally have inferior rights to receive payments from 
the issuer in comparison with the rights of holders of debt obligations or preferred stock issued by 
the issuer.&#160;&#160;In addition, holders of common stock generally have a lower priority in reorganization

emphasizes investments in 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. 
 Smaller companies may have limited product lines, markets or financial resources, or may depend on a 
limited management group.  &lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

the fund invests in foreign securities, the fund's performance will be influenced by political, social 
and economic factors affecting investments in foreign issuers.  Special risks associated with investments 
in foreign issuers include exposure to currency fluctuations, less liquidity, less developed or less 
efficient trading markets, lack of comprehensive company information, political and economic instability 
and differing auditing and legal standards.  The imposition of sanctions, confiscations, trade restrictions 
(including tariffs) and other government restrictions by the United States and other governments, or 
problems related to share registration, trade settlement, or asset custody, may result in losses for 
the fund.  Investments denominated in foreign currencies are subject to the risk that such currencies 
will decline in value relative to the U.S. dollar and affect the value of these investments held by the 
fund.  To the extent securities held by the fund trade in a market that is closed when the exchange on 
which the fund's shares trade is open, there may be deviations between the current price of a security 
and the last quoted price for the security in the closed foreign market.  These deviations could result 
in the fund experiencing premiums or discounts greater than those of ETFs that invest in domestic securities. 
 To the extent the fund's investments are focused in a limited number of foreign countries, the fund's 
performance could be more volatile than that of more geographically diversified funds.&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;  To the extent the fund invests significantly in the securities of issuers located 
in the European region, the fund is more exposed to the economic and political risks of Europe and of 
the European countries in which it invests.  Any adverse economic or political events in Europe may cause 
the fund's investments to decline in value.  The economies and markets of European countries are often 
closely connected and interdependent, and events in one country in Europe can have an adverse impact 
on other European countries. Countries in Europe will be significantly affected by the fiscal and monetary 
controls of the Economic and Monetary Union of the European Union (EU).  Changes in regulations on trade, 
decreasing imports or exports, changes in the exchange rate of the Euro, the default or threat of default 
by an EU member country on its sovereign debt, and recessions among European countries may have a significant 
adverse effect on the economies of other European countries.  In addition, one or more countries may 
abandon the Euro and/or withdraw from the EU, such as the United Kingdom's (the "U.K.'s") formal exit 
on January 31, 2020, which could potentially have an adverse effect on the value of the fund's investments. 
 There is still considerable uncertainty relating to the potential consequences associated with the U.K.'s 
exit from the EU.  &lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

securities of issuers located or doing substantial business in emerging market countries tend to be more 
volatile and less liquid than the securities of issuers located in countries with more mature economies. 
 There may be less information publicly available about an emerging market issuer than about a developed 
market issuer and/or the available information may be outdated or unreliable.  In addition, emerging 
market issuers may not be subject to accounting, auditing, legal and financial reporting standards comparable 
to those in developed markets, potentially making it difficult to evaluate such issuers.  Emerging markets 
generally have less diverse and less mature economic structures and less stable political systems than 
those of developed countries.  Additionally, investments in these countries may have restrictions that 
make it difficult or impossible for the fund to exercise rights, pursue legal remedies, and obtain judgements 
in foreign courts.  Investments in these countries may be subject to political, economic, legal, market 
and currency risks.  The risks may include less protection of property rights and uncertain political 
and economic policies, greater vulnerability to market manipulation, the imposition of capital controls 
and/or foreign investment limitations by a country, nationalization of businesses and the imposition 
of sanctions by other countries, such as the United States.   &lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>
