Depositary Receipts listed on U.S. exchanges are issued by banks or trust companies and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (&#x201c;Underlying Shares&#x201d;). When the Fund invests in Depositary Receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the Depositary Receipts may not provide a return that corresponds precisely with that of the Underlying Shares.</rr:RiskTextBlock>

Investment in dividend-paying securities could cause the Fund to underperform similar funds that invest without consideration of a company&#x2019;s track record of paying dividends. Securities of companies with a history of paying dividends may not participate in a broad market advance to the same degree as most other securities, and a sharp rise in interest rates or economic downturn could cause a company to unexpectedly reduce or eliminate its dividend. There is no guarantee that the issuers of the securities held by the Fund will declare dividends in the future or that, if declared, they will remain at their current levels or increase over time.</rr:RiskTextBlock>

This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. In addition, local, regional or global events such as war, including Russia&#x2019;s invasion of Ukraine, acts of terrorism, spread of infectious diseases or other public health issues (such as the global pandemic caused by the COVID-19 virus), recessions, rising inflation, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund&#x2019;s portfolio securities or other instruments and could result in disruptions in the trading markets.</rr:RiskTextBlock>

For example, the value of non-U.S. securities may be subject to risk of decline due to foreign currency fluctuations or to political or economic instability. Investments in ADRs also may be subject to withholding or other taxes and may be indirectly subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.</rr:RiskTextBlock>

As a result, the Fund may be more volatile than funds that invest in larger, more established companies. The securities of mid- and small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. Mid- and small-capitalization companies may be particularly sensitive to changes in interest rates, government regulation, borrowing costs, and earnings.&lt;/span&gt;</rr:RiskTextBlock>

REITs may have limited financial resources, may trade less frequently and in limited volume, and may be more volatile than other securities. REITs may be affected by changes in the value of their underlying properties or mortgages or by defaults by their borrowers or tenants. Furthermore, these entities depend upon specialized management skills, have limited diversification and are, therefore, subject to risks inherent in financing a limited number of projects. In addition, the performance of a REIT may be affected by changes in the tax laws or by its failure to qualify for tax-free pass-through of income.</rr:RiskTextBlock>

Banks, in particular, are subject to volatile interest rates, severe price competition, and extensive government oversight and regulation, which may limit certain economic activities available to banks, impact their fees and overall profitability, and establish capital maintenance requirements. In addition, banks may have concentrated portfolios of loans or investments that make them vulnerable to economic conditions that affect that industry. Insurance companies are subject to similar risks as banks, including adverse economic conditions, changes in interest rates, increased competition and government regulation, but insurance companies are more at risk from changes in tax law, government imposed premium rate caps, and catastrophic events, such as earthquakes, floods, hurricanes and terrorist acts. This sector has experienced significant losses in the recent past, and the impact of higher interest rates, more stringent capital requirements, and of recent or future regulation on any individual financial company, or on the sector as a whole, cannot be predicted.
