•

Infrastructure companies risk – Infrastructure companies may be subject to a variety of factors that may adversely affect their business or operations, including high interest costs in connection with capital construction programs, high leverage, costs associated with environmental and other regulations, the effects of economic slowdown, surplus capacity, increased competition from other providers of services, uncertainties concerning the availability of fuel at reasonable prices, the effects of energy conservation policies and other factors. Some of the specific risks that infrastructure companies may be particularly affected by, or subject to, include the following: regulatory risk, technology risk, regional or geographic risk, natural disasters risk, through-put risk, project risk, strategic asset risk, operation risk, customer risk, interest rate risk, inflation risk and financing risk.

•

Equity securities risk – Common and preferred stocks represent equity ownership in a company.  Stock markets are volatile, and equity securities generally have greater price volatility than fixed-income securities.  The price of equity or equity-related securities will fluctuate and can decline and reduce the value of a portfolio investing in equity or equity-related securities.  The value of equity or equity-related securities purchased or held by the Fund could decline if the financial condition of the companies the Fund invests in decline or if overall market and economic conditions deteriorate.  They may also decline due to factors that affect a particular industry or industries, such as labor shortages or an increase in production costs and competitive conditions within an industry.  In addition, they may decline due to general market conditions that are not specifically related to a company or industry, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates or generally adverse investor sentiment.

•

Company risk – Investments in U.S. and/or foreign-traded equity securities may fluctuate more than the values of other types of securities in response to changes in a particular company’s financial condition.

•

Stock risk – Stock markets may experience significant short-term volatility and may fall sharply at times. Different stock markets may behave differently from each other and U.S. stock markets may move in the opposite direction from one or more foreign stock markets.  The prices of individual stocks generally do not all move in the same direction at the same time and a variety of factors can affect the price of a particular company’s stock.

•

Sector risk – Companies with similar characteristics may be grouped together in broad categories called sectors. Sector risk is the risk that securities of companies within specific sectors of the economy can perform differently than the overall market. For example, this may be due to changes in the regulatory or competitive environment or changes in investor perceptions regarding a sector. Because the Fund may allocate relatively more assets to certain sectors than others, the Fund’s performance may be more susceptible to any developments which affect those sectors emphasized by the Fund.  In addition, the Fund could underperform other funds investing in similar sectors or comparable benchmarks because of the investment manager’s choice of securities within such sector.

•

Market risk – Portfolio securities may decline in value due to factors affecting securities markets generally, such as real or perceived adverse economic, political, or regulatory conditions, inflation, changes in interest or currency rates or adverse investor sentiment, public health issues, including widespread disease and virus epidemics or pandemics, war, terrorism or natural disasters, among others. Adverse market conditions may be prolonged and may not have the same impact on all types of securities.  The values of securities may fall due to factors affecting a particular issuer, industry or the securities market as a whole.

•

Investment strategy risk – The Sub-Adviser uses the principal investment strategies and other investment strategies to seek to achieve the Fund’s investment objective. Investment decisions made by the Sub-Adviser in accordance with these investment strategies may not produce the returns the Sub-Adviser expected, and may cause the Fund’s shares to decline in value or may cause the Fund to underperform other funds with similar investment objectives.

•

Managed portfolio risk – As an actively managed portfolio, the Fund's portfolio manager(s) make decisions to buy and sell holdings in the Fund's portfolio. Because of this, the value of the Fund’s investments could decline because the financial condition of an issuer may change (due to such factors as management performance, reduced demand or overall market changes), financial markets may fluctuate or overall prices may decline, the Sub-Adviser's investment techniques could fail to achieve the Fund’s investment objective or negatively affect the Fund’s investment performance, or legislative, regulatory, or tax developments may affect the investment techniques available to the Sub-Adviser of the Fund. There is no guarantee that the investment objective of the Fund will be achieved.

•

Foreign securities risk – Investments in, or exposure to, foreign securities involve risks not typically associated with U.S. investments. These risks include, among others, adverse fluctuations in foreign currency values, possible imposition of foreign withholding or other taxes on income payable on the securities, as well as adverse political, social and economic developments, such as political upheaval, acts of terrorism, financial troubles, sanctions or the threat of new or modified sanctions, or natural disasters. Many foreign securities markets, especially those in emerging market countries, are less stable, smaller, less liquid, and less regulated than U.S. securities markets, and the costs of trading in those markets is often higher than in U.S. securities markets. There may also be less publicly available information about issuers of foreign securities compared to issuers of U.S. securities. In addition, the economies of certain foreign markets may not compare favorably with the economy of the United States with respect to issues such as growth of gross national product, reinvestment of capital, resources and balance of payments position.

•

European investment risk – Investing in Europe involves many of the same risks as investing in foreign securities.  In addition, since Europe includes both developed and emerging markets, investments by the Fund will be subject to the risks associated with investments in such markets. Performance is expected to be closely tied to social, political, and economic conditions within Europe and to be more volatile than the performance of more geographically diversified funds. The European financial markets have recently experienced volatility and adverse trends due to concerns about economic downturns in, or rising government debt levels of, several European countries as well as acts of war in the region. These events may spread to other countries in Europe and may affect the value and liquidity of certain of the Fund’s investments. For example, in June 2016, the United Kingdom approved a referendum to leave the European Union (commonly known as “Brexit”). The United Kingdom left the European Union on January 31, 2020 with an eleven-month transition period ending December 31, 2020, during which the United Kingdom and the European Union agreed to a Trade and Cooperation Agreement governing the future relationship between the United Kingdom and the European Union from January 1, 2021. On January 1, 2021, European Union laws ceased to apply in the United Kingdom. Many European Union laws were transposed into English law and these transposed laws continue to apply until such time that they are repealed, replaced or amended. The United Kingdom government has enacted legislation that will repeal, replace or otherwise make substantial amendments to the European Union laws that currently apply in the United Kingdom. It is impossible to predict the consequences of these amendments on the Fund and its investments. Brexit may also create uncertainty around trade within Europe, the possibility of capital outflows from the United Kingdom, devaluation of the pound sterling, the cost of higher corporate bond spreads, and the risk that all the above could negatively impact business and consumer spending as well as foreign direct investment.

•

Emerging markets and less developed countries risk – Emerging market and less developed countries generally are located in Asia, the Middle East, Eastern Europe, Central and South America and Africa.  Investments in, or exposure to, securities that are tied economically to emerging market and less developed countries are subject to all of the risks of investments in, or exposure to, foreign securities, generally to a greater extent than in developed markets, among other risks.  Investments in securities that are tied economically to emerging markets involve greater risk from economic and political systems that typically are less developed, and likely to be less stable, than those in more advanced countries.  The Fund also will be subject to the risk of adverse foreign currency rate fluctuations.  Emerging market and less developed countries may also have economies that are predominantly based on only a few industries or dependent on revenues from particular commodities. The risks of nationalization, expropriation or other confiscation of assets of non-U.S. issuers is also greater in emerging and less developed countries. As a result of these risks, investments in securities tied economically to emerging markets tend to be more volatile than investments in securities of developed countries.

•

Currency risk – Investments in foreign currencies, securities that trade in or receive revenues in foreign currencies, or derivatives that provide exposure to foreign currencies are subject to the risk that those currencies may decline in value or, in the case of hedging positions, that the currency may decline in value relative to the currency being hedged. Currency exchange rates can be volatile and may be affected by a number of factors, such as the general economics of a country, the actions (or inaction) of U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.

•

Stapled securities risk – A stapled security is comprised of two different securities—a unit of a trust and a share of a company—that are “stapled” together and treated as a unit at all times, including for transfer or trading.  The characteristics and value of a stapled security are influenced by both underlying securities. Stapled securities are not obligations of, deposits in, or guaranteed by, the Fund.  The listing of stapled securities on a domestic or foreign exchange does not guarantee a liquid market for stapled securities.

•

Master limited partnership risk – An investment in MLP units involves some risks that differ from an investment in the common stock of a corporation.  Holders of MLP units have limited control on matters affecting the partnership.  Investing in MLPs involves certain risks related to investing in the underlying assets of the MLPs and risks associated with pooled investment vehicles.  MLPs holding credit-related investments are subject to interest rate risk and the risk of default on payment obligations by debt issuers.  MLPs that concentrate in a particular industry or a particular geographic region are subject to risks associated with such industry or region.  The benefit derived from the Fund’s investment in MLPs is largely dependent on the MLPs being treated as partnerships for federal income tax purposes. Certain MLPs may be illiquid securities.

•

Regulation S securities risk – Regulation S securities may be less liquid than publicly traded securities and may not be subject to the disclosure and other investor protection requirements that would be applicable if they were publicly traded. Accordingly, Regulation S securities may involve a high degree of business and financial risk and may result in substantial losses.

•

Rule 144A securities risk – Rule 144A securities are securities offered as exempt from registration with the SEC, but may be treated as liquid securities because there is a market for such securities.  Rule 144A securities may have an active trading market, but carry the risk that the active trading market may not continue. To the extent that institutional buyers become, for a time, uninterested in purchasing Rule 144A securities, investing in such securities could increase the Fund’s level of illiquidity.

•

Investments in IPOs risk – IPOs issued by unseasoned companies with little or no operating history are risky and highly volatile.

•

Mid-capitalization investing risk – The stocks of mid-capitalization companies can be more volatile and their shares can be less liquid than those of larger companies. Mid-capitalization companies may have limited product lines, markets or financial resources or may depend on the expertise of a few people and may be subject to more abrupt or erratic market movements than securities of larger, more established companies or the market averages in general. Securities of such issuers may lack sufficient market liquidity to effect sales at an advantageous time or without a substantial drop in price.

•

Small-capitalization investing risk – Investing in smaller companies, some of which may be newer companies or start-ups, generally involves greater risks than investing in larger, more established ones. The securities of companies with smaller market capitalizations often are less widely held and trade less frequently and in lesser quantities, and their market prices often fluctuate more, than the securities of companies with larger market capitalizations.

•

Real estate investment risk – Risks of investing in real estate securities include falling property values due to increasing vacancies in rental properties, declining rents resulting from economic, legal, tax, cultural, political or technological developments, lack of liquidity, limited diversification, and sensitivity to certain economic factors such as interest-rate changes and other market conditions. When growth is slowing, demand for property decreases and prices may decline, which could impact the value of real estate investments as well as mortgage-backed securities that may be held by the Fund.  Real estate company share prices may drop because of the failure of borrowers to pay their loans and poor management, and residential developers, in particular, could be negatively impacted by falling home prices, slower mortgage origination and rising construction costs. The securities of smaller real estate-related issuers can be more volatile and less liquid than securities of larger issuers and their issuers can have more limited financial resources.

•

REIT investment risk – The risks of investing in REITs include certain risks associated with the direct ownership of real estate and the real estate industry in general. These include risks related to general, regional and local economic conditions; difficulties in valuing and disposing of real estate; fluctuations in interest rates and property tax rates; shifts in zoning laws; environmental regulations and other governmental action; cash flow dependency; increased operating expenses; lack of availability of mortgage funds; losses due to natural disasters; overbuilding; losses due to casualty or condemnation; changes in property values and rental rates; the management skill and creditworthiness of the REIT manager; and other factors. REITs may have limited financial resources, may trade less frequently and in limited volume, may engage in dilutive offerings of securities and may be more volatile than other securities. REITs could be adversely affected by failure to maintain their exemptions from registration under the Investment Company Act of 1940, as amended, or failure to qualify for the “dividends paid deduction” under the Internal Revenue Code of 1986, as amended, which allows REITs to reduce their corporate taxable income for dividends paid to their shareholders.

•

Accounting risk – The Fund bases investment selections, in part, on information drawn from the financial statements of issuers. Financial statements may not be accurate, may reflect differing approaches with respect to auditing and reporting standards and may affect the ability of the Fund’s investment manager to identify appropriate investment opportunities.

•

Issuer risk – The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the market as a whole.  A security’s value may decline for reasons that directly relate to the issuer, such as management performance, corporate governance, financial leverage and reduced demand for the issuer’s goods or services.

•

Depositary receipts risk – Depositary receipts, such as American depositary receipts ("ADRs"), global depositary receipts ("GDRs"), and European depositary receipts ("EDRs"), may be issued in sponsored or un-sponsored programs. They may be traded in the over-the-counter (“OTC”) market or on a regional exchange, or may otherwise have limited liquidity. The prices of depositary receipts may differ from the prices of securities upon which they are based. In a sponsored program, a security issuer has made arrangements to have its securities traded in the form of depositary receipts.  In an un-sponsored program, the issuer may not be directly involved in the creation of the program. Holders of un-sponsored depositary receipts generally bear all the costs of the facility. The depository usually charges fees upon deposit and withdrawal of the underlying securities, the conversion of dividends into U.S. dollars or other currency, the disposition of non-cash distributions, and the performance of other services.   Depositary receipts involve many of the same risks as direct investments in foreign securities.  These risks include: fluctuations in currency exchange rates, which are affected by international balances of payments and other economic and financial conditions; government intervention; and speculation.  With respect to certain foreign countries, there is the possibility of expropriation or nationalization of assets, confiscatory taxation, political and social upheaval, and economic instability.  Investments in depositary receipts that are exchange traded or OTC may also subject the Fund to liquidity risk. This risk is enhanced in connection with OTC depositary receipts.

•

Preferred stock risk – Preferred stock represents an equity interest in a company that generally entitles the holder to receive, in preference to the holders of other stocks such as common stocks, dividends and a fixed share of the proceeds resulting from a liquidation of the company. Risks of preferred securities include (i) the ability of the issuer to defer or omit distributions for a stated period in its sole discretion, (ii) the potential for the security to lose value based on the credit worthiness of the issuer or its decision to defer distributions, (iii) the potential for the security to lose value in light of the increase in market interest rates (iv) the potential for the issuer to call (repay) the security or extend the term of the security, subject to the security’s terms and issuer’s discretion, which may impact the value of the security in light of prevailing market interest rates at that time, (v) the risk that the preferred securities may have a less liquid market than government securities or other equity securities issued by the issuer, and (vi) being subject to the decisions of voting shareholders of an issuer as preferred securities typically contain limited, or no, voting rights.

•

Concentration risk – The Fund may concentrate its investments in certain securities.  To the extent that the Fund focuses on particular countries, regions, industries, sectors, issuers, types of investment or limited number of securities from time to time, the Fund may be subject to greater risks of adverse economic, business or political developments in the area of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments.

•

Volatility risk – The Fund may have investments that appreciate or depreciate significantly in value over short periods of time. This may cause the Fund’s net asset value per share to experience significant appreciations or depreciations in value over short periods of time.

•

Liquidity risk – Investments in securities that are difficult to purchase or sell (illiquid or thinly-traded securities) may reduce returns if the Fund is unable to sell the securities at an advantageous time or price or achieve its desired level of exposure to a certain sector.  Liquidity risk arises, for example, from small average trading volumes, trading restrictions, or temporary suspensions of trading. To meet redemption requests, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

•

Portfolio turnover risk – Frequent changes in the securities held by the Fund, including investments made on a shorter-term basis or in derivative instruments or in instruments with a maturity of one year or less at the time of acquisition, may increase transaction costs, which may reduce performance.

•

Derivatives risk – Investments in derivatives, which are financial instruments whose value depends on, or is derived from, the value of underlying assets, reference rates, or indices, can be highly volatile and may be subject to transaction costs and certain risks, such as unanticipated changes in securities prices and global currency investment.  Derivatives also are subject to leverage risk, liquidity risk, interest rate risk, market risk, counterparty risk, and credit risk.  They also involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, interest rate or index. Gains or losses from derivatives can be substantially greater than the derivatives’ original cost.
