industries such as digital advertising, e-commerce and streaming services; media, including studios,

companies with good appreciation prospects. The portfolio manager may use either a growth or value approach 
to stock selection. When assessing opportunities among growth stocks, the portfolio manager generally 
seeks to identify companies with capable management, attractive business niches, sound financial and 
accounting practices, and a demonstrated ability to increase revenues, earnings, and cash flow consistently. 
In looking for value stocks, the portfolio manager will seek companies whose current stock prices appear 
undervalued in terms of earnings, projected cash flow, or asset value per share, and with growth potential 
temporarily unrecognized by the market. The portfolio manager also seeks to invest in companies whose 
stock prices may be temporarily depressed.&lt;/p&gt;&lt;p style="font-size:8.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;The fund&#x2019;s portfolio may hold stocks of either U.S. or non-U.S. 
companies, and may at times consist of a relatively small number of holdings. Although the fund typically 
invests a greater portion of its assets in U.S. stocks, there is no limit on the fund&#x2019;s investments 
in non-U.S. securities.&lt;/p&gt;&lt;p style="font-size:8.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;The

to trade publicly.&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:8.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;The fund is nondiversified, which means it may invest a greater percentage of

susceptible to adverse developments affecting those industries and sectors than a more broadly diversified 
fund. Because the fund invests significantly in communications and technology companies, the fund may 
perform poorly during a downturn in the communications and technology industries. Communications and 
technology companies can be adversely affected by, among other things, changes in government regulations 
or increased government scrutiny; dependency on patent protection and intellectual property rights; &lt;/span&gt;&lt;span style="font-size:8.0pt; font-family:Arial; font-style:normal; font-weight:normal; text-decoration:none;"&gt;intense 
competition; and rapid obsolescence of products and services due to product compatibility, technological 
innovations, or changing consumer preferences. Communications and technology companies may also be more

businesses.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

and markets generally, including economic, political, or regulatory developments, recessions, inflation, 
rapid interest rate changes, war, military conflict, acts of terrorism, natural disasters, and outbreaks 
of infectious illnesses or other widespread public health issues (such as the coronavirus pandemic) and 
related governmental and public responses (including sanctions). Certain events may cause instability 
across global markets, including reduced liquidity and disruptions in trading markets, while some events 
may affect certain geographic regions, countries, sectors, and industries more significantly than others. 
Government intervention in markets may impact interest rates, market volatility, and security pricing.

 Investments in the stocks of privately held companies and in companies that only recently began to publicly 
trade, such as initial public offerings or IPOs, involve greater risks than investments in stocks of 
companies that have traded publicly on an exchange for extended time periods. There is significantly 
less information available about these companies&#x2019; business models, quality of management, earnings 
growth potential, and other criteria that are normally considered when evaluating the investment prospects 
of a company. Private placements and other restricted securities held by the fund are typically considered

and tend to be difficult to value since there are no market prices and less overall financial information 
available. The adviser evaluates a variety of factors when assigning a value to these holdings, but the 
determination involves some degree of subjectivity and the value assigned for the fund may differ from 
the value assigned by other mutual funds holding the same security. &lt;/p&gt;</rr:RiskTextBlock>

or an entire market segment may become less liquid or even illiquid, sometimes abruptly, which could 
limit the fund&#x2019;s ability to purchase or sell holdings in a timely manner at a desired price. An inability 
to sell a portfolio holding can adversely affect the fund&#x2019;s overall value or prevent the fund from 
being able to take advantage of other investment opportunities. Liquidity risk may be magnified during 
periods of substantial market volatility and unexpected episodes of illiquidity may limit the fund&#x2019;s 
ability to pay redemption proceeds without selling holdings at an unfavorable time or at a suitable price. 
Large redemptions may also have a negative impact on the fund&#x2019;s overall liquidity.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

liquidity and trading volume than investments in U.S. securities and may lose value because of adverse 
local, political, social, or economic developments overseas, or due to changes in the exchange rates 
between foreign currencies and the U.S. dollar. Further, securities of non-U.S. issuers are subject to 
trading markets with potential governmental interference, varying regulatory, auditing, and accounting 
standards, and settlement and clearance practices that differ from those of U.S. issuers. Investment 
in non-U.S. securities also carries currency risk. Any attempts to hedge currency risk could be unsuccessful. 
Such investments may have higher transaction costs compared with U.S. markets. The fund&#x2019;s overall foreign 
investing risk is increased to the extent it has exposure to emerging markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

 As a nondiversified fund, the fund has the ability to invest a larger percentage of its assets in the 
securities of a smaller number of issuers than a diversified fund. As a result, poor performance by a 
single issuer could adversely affect fund performance more than if the fund were invested in a larger 
number of issuers. The fund&#x2019;s share price can be expected to fluctuate more than that of a similar 
fund that is more broadly diversified.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>
