ETFs trade like stocks, are subject to investment risk, including possible loss of principal.

Equities are subject to market, market sector, market liquidity, issuer, and investment style risks, among other factors, to varying degrees. Investing in foreign denominated and/or domiciled securities involves special risks, including changes in currency exchange rates, political, economic, and social instability, limited company information, differing auditing and legal standards, and less market liquidity. These risks generally are greater with emerging market countries.

There is no guarantee that dividend-paying companies will continue to pay, or increase, their dividend. High-dividend stocks may not experience the same capital appreciation as non-dividend paying stocks during periods of high growth for equities.

Because the fund invests significantly in companies that are engaged in the infrastructure business, the fund is more susceptible to adverse economic, regulatory, political, legal and other changes affecting such companies. Infrastructure companies are subject to a variety of factors that may adversely affect their business or operations, including high interest costs in connection with capital construction programs, costs associated with environmental and other regulations, difficulty in raising capital in adequate amounts on reasonable terms in periods of high inflation or unsettled capital markets, the effects of economic slowdown and surplus capacity, increased competition from other providers of services, uncertainties concerning the availability of fuel at reasonable prices, the effects of energy conservation policies, service interruption due to environmental, operational or other mishaps, and other factors.

The fund is non-diversified, which means that the fund may invest a relatively high percentage of its assets in a limited number of issuers. Therefore, the fund's performance may be more vulnerable to changes in the market value of a single issuer or group of issuers and more susceptible to risks associated with a single economic, political or regulatory occurrence than a diversified fund.

Recent market risks include pandemic risks related to COVID-19. The effects of COVID-19 have contributed to increased volatility in global markets and will likely affect certain countries, companies, industries and market sectors more dramatically than others. To the extent the fund may overweight its investments in certain countries, companies, industries or market sectors, such positions will increase the fund's exposure to risk of loss from adverse developments affecting those countries, companies, industries or sectors.

Although fund shares are listed for trading on an exchange and may be listed or traded on other U.S. and non-U.S. stock exchanges as well, there can be no assurance that an active trading market for such fund shares will develop or be maintained. Trading in fund shares may be halted due to market conditions or for reasons that, in the view of the listing exchange, make trading in fund shares inadvisable. In addition, trading in fund shares on an exchange is subject to trading halts caused by extraordinary market volatility pursuant to exchange "circuit breaker" rules. There can be no assurance that the requirements of the listing exchange necessary to maintain the listing of the fund will continue to be met or will remain unchanged or that fund shares will trade with any volume, or at all, on any stock exchange.

Please refer to the prospectus for a more complete discussion of the fund's main risks.
