Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including: inflation (or expectations for inflation); deflation (or expectations for deflation); interest rates; market instability; financial system instability; debt crises and downgrades; embargoes; tariffs; sanctions and other trade barriers; regulatory events; other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

Risk [Text Block]

Real Estate Investment Trust (REIT) Risk. Investments in REITs are subject to the same risks as direct investments in real estate and mortgages which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy and environmental factors. In addition, the underlying mortgage loans may be subject to the risks of default or of prepayments that occur earlier or later than expected, and such loans may also include so-called “sub-prime” mortgages. The value of REITs will also rise and fall in response to the management skill and creditworthiness of the issuer. In particular, the value of these securities may decline when interest rates rise and will also be affected by the real estate market and by the management of the underlying properties. REITs may be more volatile and/or more illiquid than other types of equity securities. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Depositary Receipt Risk. Depositary receipts are subject to many of the risks associated with investing directly in foreign securities, including, among other things, political, social and economic developments abroad, currency movements and different legal, regulatory and tax environments. In addition, holders of depositary receipts may have limited voting rights, may not have the same rights afforded to stockholders of a typical company in the event of a corporate action, such as an acquisition, merger or rights offering, and may experience difficulty in receiving company stockholder communications. There is no guarantee that a financial institution will continue to sponsor a depositary receipt, or that the depositary receipts will continue to trade on an exchange, either of which could adversely affect the liquidity, availability and pricing of the depositary receipt. Changes in foreign currency exchange rates will affect the value of depositary receipts and, therefore, may affect the value of your investment in the Fund.

Limited Partnership and MLP Risk. Investments in securities (units) of partnerships, including MLPs, involve risks that differ from an investment in common stock.  Holders of the units of limited partnerships have more limited control and limited rights to vote on matters affecting the

partnership.  Certain tax risks are associated with an investment in units of limited partnerships.  In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a limited partnership, including a conflict arising as a result of incentive distribution payments. In addition, investments in certain investment vehicles, such as limited partnerships and MLPs, may be illiquid. Such partnership investments may also not provide daily pricing information to their investors, which will require the Fund to employ fair value procedures to value its holdings in such investments.

Foreign Securities Risk. Investing in foreign securities typically involves more risks than investing in U.S. securities, and includes risks associated with: (i) internal and external political and economic developments – e.g., the political, economic and social policies and structures of some foreign countries may be less stable and more volatile than those in the U.S. or some foreign countries may be subject to trading restrictions or economic sanctions; (ii) trading practices – e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S.; (iii) availability of information – e.g., foreign issuers may not be subject to the same disclosure, accounting and financial reporting standards and practices as U.S. issuers; (iv) limited markets – e.g., the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and (v) currency exchange rate fluctuations and policies.

Emerging Markets Risk. In addition to the risks of foreign securities in general, investments in emerging markets may be riskier than investments in or exposure to investments in the U.S. and other developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, a higher degree of political and economic instability (which can freeze, restrict or suspend transactions in those investments, including cash), the impact of economic sanctions, less governmental regulation and supervision of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.

Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets and the risk may be higher in emerging markets.

There is an additional increased risk of price volatility associated with frontier market countries (pre-emerging markets), which may be further magnified by currency fluctuations relative to the U.S. dollar.  Frontier market countries generally have smaller economies or less developed capital markets than in more advanced emerging markets and, as a result, the risks of investing in emerging market countries may be magnified in frontier market countries.

Risk [Text Block]

Real Estate Investment Trust (REIT) and Foreign Real Estate Company Risk. Investments in REITs and foreign real estate companies are subject to the same risks as direct investments in real estate and mortgages which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy and environmental factors. In addition, the underlying mortgage loans may be subject to the risks of default or of prepayments that occur earlier or later than expected, and such loans may also include so-called “sub-prime” mortgages. The value of REITs and foreign real estate companies will also rise and fall in response to the management skill and creditworthiness of the issuer. In particular, the value of these securities may decline when interest rates rise and will also be affected by the real estate market and by the management of the underlying properties. REITs and foreign real estate companies may be more volatile and/or more illiquid than other types of equity securities. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT or foreign real estate company in which it invests in addition to the expenses of the Fund.

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including: inflation (or expectations for inflation); deflation (or expectations for deflation); interest rates; market instability; financial system instability; debt crises and downgrades; embargoes; tariffs; sanctions and other trade barriers; regulatory events; other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

Sector Emphasis Risk. The securities of companies in the same or related businesses, if comprising a significant portion of the International Value Fund’s portfolio, could react in some circumstances negatively to market conditions, interest rates and economic, regulatory or financial developments and adversely affect the value of the portfolio to a greater extent than if such business comprised a lesser portion of the Fund’s portfolio.◦Financial Services Sector Risk. Risks of investing in the financial services sector include: (i) systemic risk: factors outside the control of a particular financial institution may adversely affect the ability of the financial institution to operate normally or may impair its financial condition; (ii) regulatory actions: financial services companies may suffer setbacks if regulators change the rules under which they operate; (iii) changes in interest rates: unstable and/or rising interest rates may have a disproportionate effect on companies in the financial services sector; (iv) non-diversified loan portfolios: financial services companies may have concentrated portfolios that make them vulnerable to economic conditions that affect an industry; (v) credit: financial services companies may have exposure to investments or agreements that may lead to losses; and (vi) competition: the financial services sector has become increasingly competitive.

Depositary Receipt Risk. Depositary receipts are subject to many of the risks associated with investing directly in foreign securities, including, among other things, political, social and economic developments abroad, currency movements and different legal, regulatory and tax environments. In addition, holders of depositary receipts may have limited voting rights, may not have the same rights afforded to stockholders of a typical company in the event of a corporate action, such as an acquisition, merger or rights offering, and may experience difficulty in receiving company stockholder communications. There is no guarantee that a financial institution will continue to sponsor a depositary receipt, or that the depositary receipts will continue to trade on an exchange, either of which could adversely affect the liquidity, availability and pricing of the depositary receipt. Changes in foreign currency exchange rates will affect the value of depositary receipts and, therefore, may affect the value of your investment in the Fund.

Risk [Text Block]

Limited Partnership and MLP Risk. Investments in securities (units) of partnerships, including MLPs, involve risks that differ from an investment in common stock. Holders of the units of limited partnerships have more limited control and limited rights to vote on matters affecting the partnership. Certain tax risks are associated with an investment in units of limited partnerships. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a limited partnership, including a conflict arising as a result of incentive distribution payments. In addition, investments in certain investment vehicles, such as limited partnerships and MLPs, may be illiquid. Such partnership investments may also not provide daily pricing information to their investors, which will require the Fund to employ fair value procedures to value its holdings in such investments.

Foreign Securities Risk. Foreign securities are subject to special risks in addition to those of issuers located in the U.S. Foreign securities can be more volatile than domestic (U.S.) securities. Securities markets of other countries are generally smaller than U.S. securities markets. Many foreign securities may be less liquid than U.S. securities, which could affect the International Value Fund’s investments. Foreign securities may be adversely affected by political instability; changes in currency exchange rates; inefficient markets and higher transaction costs; foreign economic conditions; or inadequate or different regulatory and accounting standards.

Emerging Markets Risk.  In addition to the risks of foreign securities in general, investments in emerging markets may be riskier than investments in or exposure to investments in the U.S. and other developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, a higher degree of political and economic instability (which can freeze, restrict or suspend transactions in those investments, including cash), the impact of economic sanctions, less governmental regulation and supervision of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.

Currency Risk. Changes in foreign currency exchange rates will affect the value of what the Fund owns and the Fund’s share price. Generally, when the U.S. dollar rises in value against a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets and the risk may be higher in emerging markets.
