RISK FACTORS

The risks of investing in certain types of securities are described below. Risks are applicable to a Fund only if and to the extent that corresponding investments, or indirect exposures to such investments through derivative contracts, are consistent with and permitted by the Fund’s investment objective and policies. The value of an individual security or a particular type of security can be more volatile than the market as a whole and can perform differently than the value of the market as a whole.

Cash Holdings Risk

A Fund may be subject to delays in making investments when significant purchases or redemptions of Fund shares cause the Fund to have an unusually large cash position. When a Fund has a higher than normal cash position, it may incur “cash drag,” which is the opportunity cost of holding a significant cash position. This significant cash position might cause a Fund to miss investment opportunities it otherwise would have benefitted from if fully invested, or might cause the Fund to pay more for investments in a rising market, potentially reducing Fund performance.

Non-Diversification

A fund that is non-diversified is not limited as to the percentage of its assets that may be invested in any one issuer, and as to the percentage of the outstanding voting securities of such issuer that may be owned, except by the fund’s own investment restrictions. In contrast, a diversified fund, as to at least 75% of the value of its total assets, generally may not invest more than five percent of its total assets in the securities, or own more than ten percent of the outstanding voting securities, of any one issuer.

A fund that is non-diversified may invest a high percentage of its assets in the securities of a small number of issuers, may invest more of its assets in the securities of a single issuer, and may be affected more than a diversified fund by a change in the financial condition of any of these issuers or by the financial markets’ assessment of any of these issuers.

Collateralized Debt Obligations

The risks of an investment in a CDO depend largely on the quality of the collateral securities and the class of the instrument in which a Fund invests. Normally, CDOs are privately offered and sold, and thus, are not registered under the securities laws. As a result, investments in CDOs may be characterized by a Fund as illiquid; however an active dealer market may exist for CDOs, allowing them to qualify for treatment as liquid under Rule 144A transactions. In addition to the normal risks associated with fixed-income securities discussed elsewhere in this SAI and the Prospectuses (e.g., interest rate risk and default risk), CDOs carry risks including, but are not limited to the possibility that: (i) distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) a Fund may invest in CDO classes that are subordinate to other classes of the CDO; and (iv) the complex structure of the CDO may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results.

Cybersecurity and Operational Risk

Cybersecurity breaches are either intentional or unintentional events that allow an unauthorized party to gain access to Fund assets, customer data, or proprietary information, or cause a Fund or Fund service provider to suffer data

corruption or lose operational functionality. Intentional cybersecurity incidents include: unauthorized access to systems, networks, or devices (such as through “hacking” activity); infection from computer viruses or other malicious software code; and attacks that shut down, disable, slow, or otherwise disrupt operations, business processes, or website access or functionality. In addition, unintentional incidents can occur, such as the inadvertent release of confidential information.

A cybersecurity breach could result in the loss or theft of customer data or funds, the inability to access electronic systems (“denial of services”), loss or theft of proprietary information or corporate data, physical damage to a computer or network system, or costs associated with system repairs, any of which could have a substantial impact on a Fund. For example, in a denial of service, Fund shareholders could lose access to their electronic accounts indefinitely, and employees of the Advisor, a subadvisor, or the Funds’ other service providers may not be able to access electronic systems to perform critical duties for the Funds, such as trading, NAV calculation, shareholder accounting, or fulfillment of Fund share purchases and redemptions. Cybersecurity incidents could cause a Fund, the Advisor, a subadvisor, or other service provider to incur regulatory penalties, reputational damage, compliance costs associated with corrective measures, or financial loss. They may also result in violations of applicable privacy and other laws. In addition, such incidents could affect issuers in which a Fund invests, thereby causing the Fund’s investments to lose value.

Cyber-events have the potential to affect materially the Funds and the advisor’s relationships with accounts, shareholders, clients, customers, employees, products, and service providers. The Funds have established risk management systems reasonably designed to seek to reduce the risks associated with cyber-events. There is no guarantee that the Funds will be able to prevent or mitigate the impact of all cyber-events.

The Funds are exposed to operational risk arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Funds’ service providers, counterparties, or other third parties, failed or inadequate processes, and technology or system failures.

The Advisor, each subadvisor, and their affiliates have established risk management systems that seek to reduce cybersecurity and operational risks, and business continuity plans in the event of a cybersecurity breach or operational failure. However, there are inherent limitations in such plans, including that certain risks have not been identified, and there is no guarantee that such efforts will succeed, especially since none of the Advisor, the Subadvisor, or their affiliates controls the cybersecurity or operations systems of the Funds’ third-party service providers (including the Funds’ custodian), or those of the issuers of securities in which the Funds invest.

Equity Securities

Equity securities include common, preferred and convertible preferred stocks and securities the values of which are tied to the price of stocks, such as rights, warrants and convertible debt securities. Common and preferred stocks represent equity ownership in a company. Stock markets are volatile. The price of equity securities will fluctuate and can decline and reduce the value of a Fund’s investment in equities. The price of equity securities fluctuates based on changes in a company’s financial condition and overall market and economic conditions. The value of equity securities purchased by a Fund could decline if the financial condition of the issuers of these securities declines or if overall market and economic conditions deteriorate. Even Funds that invest in high quality or “blue chip” equity securities or securities of established companies with large market capitalizations (which generally have strong financial characteristics) can be negatively impacted by poor overall market and economic conditions. Companies with large market capitalizations also may have less growth potential than smaller companies and may be able to react less quickly to change in the marketplace.

Investments in the stocks of privately held companies and newly public companies involve greater risks than investments in stocks of companies that have traded publicly on an exchange for extended time periods. Investments in such companies are less liquid and difficult to value, and there is significantly less information available about these companies’ business models, quality of management, earnings growth potential, and other criteria used to evaluate their investment prospects.

Fixed-Income Securities

Fixed-income securities generally are subject to two principal types of risks: (a) interest rate risk; and (b) credit quality risk. Fixed-income securities are also subject to liquidity risk.

Interest Rate Risk. Fixed-income securities are affected by changes in interest rates. When interest rates decline, the market value of the fixed-income securities generally can be expected to rise. Conversely, when interest rates rise, the market value of fixed-income securities generally can be expected to decline. Recent and potential future changes in government monetary policy may affect the level of interest rates.

The longer a fixed-income security’s duration, the more sensitive it will be to changes in interest rates. Similarly, a fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates that incorporates a security’s yield, coupon, final maturity, and call features, among other characteristics. All other things remaining equal, for each one percentage point increase in interest rates, the value of a portfolio of fixed-income investments would generally be expected to decline by one percent for every year of the portfolio’s average duration above zero. For example, the price of a bond fund with an average duration of eight years would be expected to fall approximately 8% if interest rates rose by one percentage point. The maturity of a security, another commonly used measure of price sensitivity, measures only the time until final payment is due, whereas duration takes into account the pattern of all payments of interest and principal on a security over time, including how these payments are affected by prepayments and by changes in interest rates, as well as the time until an interest rate is reset (in the case of variable-rate securities).

Credit Quality Risk . Fixed-income securities are subject to the risk that the issuer of the security will not repay all or a portion of the principal borrowed and will not make all interest payments. If the credit quality of a fixed-income security deteriorates after a Fund has purchased the security, the market value of the security may decrease and lead to a decrease in the value of the Fund’s investments. Funds that may invest in lower rated fixed-income securities are riskier than funds that may invest in higher rated fixed-income securities.

Liquidity Risk. Liquidity risk may result from the lack of an active market, the reduced number of traditional market participants, or the reduced capacity of traditional market participants to make a market in fixed-income securities. The capacity of traditional dealers to engage in fixed-income trading has not kept pace with the bond market’s growth. As a result, dealer inventories of corporate bonds, which indicate the ability to “make markets,” i.e., buy or sell a security at the quoted bid and ask price, respectively, are at or near historic lows relative to market size. Because market makers provide stability to fixed-income markets, the significant reduction in dealer inventories could lead to decreased liquidity and increased volatility, which may become exacerbated during periods of economic or political stress. In addition, liquidity risk may be magnified in a rising interest rate environment in which investor redemptions from fixed-income funds may be higher than normal; the selling of fixed-income securities to satisfy fund shareholder redemptions may result in an increased supply of such securities during periods of reduced investor demand due to a lack of buyers, thereby impairing the fund’s ability to sell such securities. The secondary market for certain tax-exempt securities tends to be less well-developed or liquid than many other securities markets, which may adversely affect the fund’s ability to sell such securities at attractive prices.

Master Limited Partnership (MLP) Risk

Investing in MLPs involves certain risks related to investing in the underlying assets of 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 securities. In addition, investments in the debt and securities of MLPs involve certain other risks, including risks related to limited control and limited rights to vote on matters affecting MLPs, risks related to potential conflicts of interest between an MLP and the MLP’s general partner, cash flow risks, dilution risks and risks related to the general partner’s right to require unit-holders to sell their common units at an undesirable time or price. The fund’s investments in MLPs may be subject to legal and other restrictions on resale or may be less liquid than publicly traded securities. Certain MLP securities may trade in lower volumes due to their smaller capitalizations, and may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity to enable the fund to effect sales at an advantageous time or without a substantial drop in price. If the fund is one of the largest investors in an MLP, it may be more difficult for the fund to buy and sell significant amounts of

such investments without an unfavorable impact on prevailing market prices. Larger purchases or sales of MLP investments by the fund in a short period of time may cause abnormal movements in the market price of these investments. As a result, these investments may be difficult to dispose of at an advantageous price when the fund desires to do so. During periods of interest rate volatility, these investments may not provide attractive returns, which may adversely impact the overall performance of the fund. MLPs in which the fund may invest operate oil, natural gas, petroleum, or other facilities within the energy sector. As a result, the fund will be susceptible to adverse economic, environmental, or regulatory occurrences impacting the energy sector.

Municipal Obligations

If localities and/or authorities in a given state default on their debt obligations, this may in turn negatively affect the marketability and, therefore, the liquidity of such state’s municipal instruments. The credit risk of municipal securities is directly related to a state’s financial condition, and is subject to change rapidly and without notice. The credit ratings of municipal obligations also are affected by the credit ratings of their insurers, which may be and have been negatively affected by adverse economic conditions, such as the subprime mortgage crisis. A drop in a municipal obligation’s credit rating also may affect its marketability, which may in turn impact a Fund’s performance. In addition, the inability of bond issuers to market municipal bonds may lead to “failed auctions,” which would reset periodic rates to rates in excess of those that would otherwise prevail in a short-term market. Also, the value of municipal obligations may be difficult to measure in a given economic environment, since valuation subject to external influences may not reflect the intrinsic, underlying value of a state’s municipal obligations. These events may lower a Fund’s NAV, and the length and severity of such market turbulence may be difficult to determine.

Hybrid Instruments

The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, swaps, and currencies. Therefore, an investment in a hybrid instrument may include significant risks not associated with a similar investment in a traditional debt instrument with a fixed principal amount, is denominated in U.S. dollars, or that bears interest either at a fixed rate or a floating rate determined by reference to a common, nationally published benchmark. The risks of a particular hybrid instrument will depend upon the terms of the instrument, but may include, without limitation, the possibility of significant changes in the benchmarks or the prices of underlying assets to which the instrument is linked. These risks generally depend upon factors unrelated to the operations or credit quality of the issuer of the hybrid instrument and that may not be readily foreseen by the purchaser. Such factors include economic and political events, the supply and demand for the underlying assets, and interest rate movements. In recent years, various benchmarks and prices for underlying assets have been highly volatile, and such volatility may be expected in the future. See “Hedging and Other Strategic Transactions” for a description of certain risks associated with investments in futures, options, swaps, and forward contracts.

Volatility. Hybrid instruments are potentially more volatile and carry greater market risks than traditional debt instruments. Depending on the structure of the particular hybrid instrument, changes in a benchmark may be magnified by the terms of the hybrid instrument and have an even more dramatic and substantial effect upon the value of the hybrid instrument. Also, the prices of the hybrid instrument and the benchmark or underlying asset may not move in the same direction or at the same time.

Leverage Risk. Hybrid instruments may bear interest or pay preferred dividends at below market (or even relatively nominal) rates. Alternatively, hybrid instruments may bear interest at above market rates, but bear an increased risk of principal loss (or gain). For example, an increased risk of principal loss (or gain) may result if “leverage” is used to structure a hybrid instrument. Leverage risk occurs when the hybrid instrument is structured so that a change in a benchmark or underlying asset is multiplied to produce a greater value change in the hybrid instrument, thereby magnifying the risk of loss, as well as the potential for gain.

Liquidity Risk. Hybrid instruments also may carry liquidity risk since the instruments are often “customized” to meet the needs of a particular investor. Therefore, the number of investors that would be willing and able to buy such instruments in the secondary market may be smaller than for more traditional debt securities. In addition, because the purchase and sale of hybrid instruments could take place in an over-the-counter (“OTC”) market without the guarantee of a central clearing organization or in a transaction between a Fund and the issuer of the hybrid instrument, the

creditworthiness of the counterparty or issuer of the hybrid instrument would be an additional risk factor, which the Fund would have to consider and monitor.

Lack of U.S. Regulation. Hybrid instruments may not be subject to regulation of the Commodity Futures Trading Commission (the “CFTC”), which generally regulates the trading of swaps and commodity futures by U.S. persons, the SEC, which regulates the offer and sale of securities by and to U.S. persons, or any other governmental regulatory authority.

Credit and Counterparty Risk. The issuer or guarantor of a hybrid instrument may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise honor its obligations. Funds that invest in hybrid instruments are subject to varying degrees of risk that the issuers of the securities will have their credit rating downgraded or will default, potentially reducing a Fund’s share price and income level.

The various risks discussed above with respect to hybrid instruments, particularly the market risk of such instruments, may cause significant fluctuations in the NAV of a Fund that invests in such instruments.

Investment Grade Fixed-Income Securities in the Lowest Rating Category

Investment grade fixed-income securities in the lowest rating category (i.e., rated “Baa” by Moody’s and “BBB” by S&P or Fitch, as applicable, and comparable unrated securities) involve a higher degree of risk than fixed-income securities in the higher rating categories. While such securities are considered investment grade quality and are deemed to have adequate capacity for payment of principal and interest, such securities lack outstanding investment characteristics and have speculative characteristics as well. For example, changes in economic conditions or other circumstances are more likely to lead to a weakened capacity to make principal and interest payments than is the case with higher grade securities.

Lower Rated Fixed-Income Securities

Lower rated fixed-income securities are defined as securities rated below investment grade (e.g., rated “Ba” and below by Moody’s, or “BB” and below by S&P or Fitch). The principal risks of investing in these securities are as follows:

Risk to Principal and Income. Investing in lower rated fixed-income securities is considered speculative. While these securities generally provide greater income potential than investments in higher rated securities, there is a greater risk that principal and interest payments will not be made. Issuers of these securities may even go into default or become bankrupt.

Price Volatility. The price of lower rated fixed-income securities may be more volatile than securities in the higher rating categories. This volatility may increase during periods of economic uncertainty or change. The price of these securities is affected more than higher rated fixed-income securities by the market’s perception of their credit quality especially during times of adverse publicity. In the past, economic downturns or an increase in interest rates have, at times, caused more defaults by issuers of these securities and may do so in the future. Economic downturns and increases in interest rates have an even greater effect on highly leveraged issuers of these securities.

Liquidity. The market for lower rated fixed-income securities may have more limited trading than the market for investment grade fixed-income securities. Therefore, it may be more difficult to sell these securities and these securities may have to be sold at prices below their market value in order to meet redemption requests or to respond to changes in market conditions.

Dependence on Subadvisor’s Own Credit Analysis. While a subadvisor to a Fund may rely on ratings by established credit rating agencies, it also will supplement such ratings with its own independent review of the credit quality of the issuer. Therefore, the assessment of the credit risk of lower rated fixed-income securities is more dependent on the subadvisor’s evaluation than the assessment of the credit risk of higher rated securities.

Additional Risks Regarding Lower Rated Corporate Fixed-Income Securities. Lower rated corporate debt securities (and comparable unrated securities) tend to be more sensitive to individual corporate developments and changes in economic conditions than higher-rated corporate fixed-income securities.

Issuers of lower rated corporate debt securities also may be highly leveraged, increasing the risk that principal and income will not be repaid.

Additional Risks Regarding Lower Rated Foreign Government Fixed-Income Securities. Lower rated foreign government fixed-income securities are subject to the risks of investing in emerging market countries described under “Risk Factors – Foreign Securities.” In addition, the ability and willingness of a foreign government to make payments on debt when due may be affected by the prevailing economic and political conditions within the country. Emerging market countries may experience high inflation, interest rates and unemployment as well as exchange rate fluctuations that adversely affect trade, and political uncertainty or instability. These factors increase the risk that a foreign government will not make payments when due.

Market Events

Events in certain sectors historically have resulted, and may in the future result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. These events have included, but are not limited to: bankruptcies, corporate restructurings, and other events related to the sub-prime mortgage crisis in 2008; governmental efforts to limit short selling and high frequency trading; measures to address U.S. federal and state budget deficits; social, political, and economic instability in Europe; economic stimulus by the Japanese central bank; steep declines in oil prices; dramatic changes in currency exchange rates; and China’s economic slowdown. Interconnected global economies and financial markets increase the possibility that conditions in one country or region might adversely impact issuers in a different country or region. Both domestic and foreign equity markets have experienced increased volatility and turmoil, with issuers that have exposure to the real estate, mortgage, and credit markets particularly affected. Banks and financial services companies could suffer losses if interest rates continue to rise or economic conditions deteriorate.

In addition, relatively high market volatility and reduced liquidity in credit and fixed-income markets may adversely affect many issuers worldwide. Actions taken by the U.S. Federal Reserve (Fed) or foreign central banks to stimulate or stabilize economic growth, such as interventions in currency markets, could cause high volatility in the equity and fixed-income markets. Reduced liquidity may result in less money being available to purchase raw materials, goods, and services from emerging markets, which may, in turn, bring down the prices of these economic staples. It may also result in emerging-market issuers having more difficulty obtaining financing, which may, in turn, cause a decline in their securities prices.

In addition, while interest rates have been unusually low in recent years in the United States and abroad, any decision by the Fed to adjust the target fed funds rate, among other factors, could cause markets to experience continuing high volatility. A significant increase in interest rates may cause a decline in the market for equity securities. Also, regulators have expressed concern that rate increases may contribute to price volatility. These events and the possible resulting market volatility may have an adverse effect on the Funds.

Political turmoil within the United States and abroad may also impact a Fund. Although the U.S. government has honored its credit obligations, it remains possible that the United States could default on its obligations. While it is impossible to predict the consequences of such an unprecedented event, it is likely that a default by the United States would be highly disruptive to the U.S. and global securities markets and could significantly impair the value of a Fund’s investments. Similarly, political events within the United States at times have resulted, and may in the future result, in a shutdown of government services, which could negatively affect the U.S. economy, decrease the value of many Fund investments, and increase uncertainty in or impair the operation of the U.S. or other securities markets. The U.S. is also considering significant new investments in infrastructure and national defense which, coupled with lower federal taxes, could lead to increased government borrowing and higher interest rates. While these proposed policies are going through the political process, the equity and debt markets may react strongly to expectations, which could increase volatility, especially if the market’s expectations for changes in government policies are not borne out.

Uncertainties surrounding the sovereign debt of a number of European Union (“EU”) countries and the viability of the EU have disrupted and may in the future disrupt markets in the United States and around the world. If one or more countries leave the EU or the EU dissolves, the world’s securities markets likely will be significantly disrupted. In June 2016, the United Kingdom approved a referendum to leave the EU, commonly referred to as “Brexit.” There is significant market uncertainty regarding Brexit’s ramifications, and the range and potential implications of possible political, regulatory, economic, and market outcomes are difficult to predict. Political and military events, including in North Korea, Venezuela, Syria, and other areas of the Middle East, and nationalist unrest in Europe, also may cause market disruptions.

In addition, there is a risk that the prices of goods and services in the United States and many foreign economies may decline over time, known as deflation. Deflation may have an adverse effect on stock prices and creditworthiness and may make defaults on debt more likely. If a country’s economy slips into a deflationary pattern, it could last for a prolonged period and may be difficult to reverse.

Small and Medium Size Companies

Survival of Small or Unseasoned Companies. Companies that are small or unseasoned (i.e., less than three years of operating history) are more likely than larger or established companies to fail or not to accomplish their goals. As a result, the value of their securities could decline significantly. These companies are less likely to survive since they are often dependent upon a small number of products and may have limited financial resources and a small management group.

Changes in Earnings and Business Prospects. Small or unseasoned companies often have a greater degree of change in earnings and business prospects than larger or established companies, resulting in more volatility in the price of their securities.

Liquidity. The securities of small or unseasoned companies may have limited marketability. This factor could cause the value of a Fund’s investments to decrease if it needs to sell such securities when there are few interested buyers.

Impact of Buying or Selling Shares. Small or unseasoned companies usually have fewer outstanding shares than larger or established companies. Therefore, it may be more difficult to buy or sell large amounts of these shares without unfavorably impacting the price of the security.

Publicly Available Information. There may be less publicly available information about small or unseasoned companies. Therefore, when making a decision to purchase a security for a Fund, a subadvisor may not be aware of problems associated with the company issuing the security.

Medium Size Companies. Investments in the securities of medium sized companies present risks similar to those associated with small or unseasoned companies although to a lesser degree due to the larger size of the companies.

Foreign Securities

Currency Fluctuations. Investments in foreign securities may cause a Fund to lose money when converting investments from foreign currencies into U.S. dollars. A Fund may attempt to lock in an exchange rate by purchasing a foreign currency exchange contract prior to the settlement of an investment in a foreign security. However, a Fund may not always be successful in doing so, and it could still lose money.

Political and Economic Conditions. Investments in foreign securities subject a Fund to the political or economic conditions of the foreign country. These conditions could cause the Fund’s investments to lose value if these conditions deteriorate for any reason. This risk increases in the case of emerging market countries which are more likely to be politically unstable. Political instability could cause the value of any investment in the securities of an issuer based in a foreign country to decrease or could prevent or delay a Fund from selling its investment and taking the money out of the country.

Removal of Proceeds of Investments from a Foreign Country. Foreign countries, especially emerging market countries, often have currency controls or restrictions that may prevent or delay a Fund from taking money out of the country or may impose additional taxes on money removed from the country. Therefore, a Fund could lose money if it is not permitted to remove capital from the country or if there is a delay in taking the assets out of the country, since the value of the assets could decline during this period or the exchange rate to convert the assets into U.S. dollars could worsen.

Nationalization of Assets. Investments in foreign securities subject a Fund to the risk that the company issuing the security may be nationalized. If the company is nationalized, the value of the company’s securities could decrease in value or even become worthless.

Settlement of Sales. Foreign countries, especially emerging market countries, also may have problems associated with settlement of sales. Such problems could cause a Fund to suffer a loss if a security to be sold declines in value while settlement of the sale is delayed.

Investor Protection Standards. Foreign countries, especially emerging market countries, may have less stringent investor protection and disclosure standards than the U.S. Therefore, when making a decision to purchase a security for a Fund, the subadvisor may not be aware of problems associated with the company issuing the security and may not enjoy the same legal rights as those provided in the U.S.

European Risk

Countries in Europe may be significantly affected by fiscal and monetary controls implemented by the EU and European Economic and Monetary Union (“EMU”), which require member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls. Decreasing imports or exports, changes in governmental or other regulations on trade, changes in the exchange rate of the Euro, the default or threat of default by one or more EU member countries on its sovereign debt, and/or an economic recession in one or more EU member countries may have a significant adverse effect on the economies of other EU member countries and major trading partners outside Europe.

In recent years, the European financial markets have experienced volatility and adverse trends due to concerns about economic downturns, rising government debt levels and the possible default of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. Several countries, including Greece and Italy, have agreed to multi-year bailout loans from the European Central Bank, the IMF, and other institutions. A default or debt restructuring by any European country, such as the restructuring of Greece’s outstanding sovereign debt, can adversely impact holders of that country’s debt and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed above, and can affect exposures to other EU countries and their financial companies as well. The manner in which the EU and EMU responded to the global recession and sovereign debt issues raised questions about their ability to react quickly to rising borrowing costs and the potential default by Greece and other countries of their sovereign debt and revealed a lack of cohesion in dealing with the fiscal problems of member states. To address budget deficits and public debt concerns, a number of European countries have imposed strict austerity measures and comprehensive financial and labor market reforms, which could increase political or social instability. Many European countries continue to suffer from high unemployment rates.

Uncertainties regarding the viability of the EU have impacted and may continue to impact markets in the United States and around the world. If one or more countries leave the EU or the EU dissolves, securities markets would likely be significantly disrupted. In June 2016, the United Kingdom (the “UK”) approved a referendum to leave the EU, commonly referred to as “Brexit,” which sparked depreciation in the value of the British pound and heightened risk of continued worldwide economic volatility. Pursuant to Article 50 of the Treaty of Lisbon, the UK gave notice in March 2017 of its withdrawal from the EU and commenced negotiations on the terms of withdrawal. The negotiation period could last for two years or more from the notice date, and during that period there might be considerable uncertainty as to the arrangements that might apply to the UK’s relationships with the EU and other countries following its anticipated withdrawal. This long-term uncertainty might affect other countries in the EU and elsewhere. It is also possible that the UK could initiate another referendum on the issue of Brexit, or that various countries within the UK, such as Scotland, could seek to separate and remain a part of the EU.

The UK has one of the largest economies in Europe and is a major trading partner with the other EU countries and the United States. If implemented, Brexit might negatively affect The City of London’s economy, which is heavily dominated by financial services, as banks might be forced to move staff and comply with two separate sets of rules or lose business to banks in Continental Europe. In addition, Brexit would likely create additional economic stresses for the UK, including the potential for decreased trade, capital outflows, devaluation of the British pound, wider corporate bond spreads due to uncertainty, and declines in business and consumer spending as well as foreign direct investment. Further, the UK’s departure from the EU would potentially cause volatility within the EU, which could trigger prolonged economic downturns in certain European countries or spark additional member states to contemplate departing the EU (thereby exacerbating political instability in the region).

Investing in the securities of Eastern European issuers is highly speculative and involves risks not usually associated with investing in the more developed markets of Western Europe. Securities markets of Eastern European countries typically are less efficient and have lower trading volume, lower liquidity, and higher volatility than more developed markets. Eastern European economies also may be particularly susceptible to disruption in the international credit market due to their reliance on bank related inflows of capital.

To the extent that a Fund invests in European securities, it may be exposed to these risks through its direct investments in such securities, including sovereign debt, or indirectly through investments in money market funds and financial institutions with significant investments in such securities.

Negative Interest Rates. Certain countries have recently experienced negative interest rates on deposits and debt instruments have traded at negative yields. A negative interest rate policy is an unconventional central bank monetary policy tool where nominal target interest rates are set with a negative value (i.e., below zero percent) intended to help create self-sustaining growth in the local economy. Negative interest rates may become more prevalent among non-U.S. issuers, and potentially within the U.S. For example, if a bank charges negative interest, instead of receiving interest on deposits, a depositor must pay the bank fees to keep money with the bank.

These market conditions may increase a Fund’s exposures to interest rate risk. To the extent a Fund has a bank deposit or holds a debt instrument with a negative interest rate to maturity, the Fund would generate a negative return on that investment. While negative yields can be expected to reduce demand for fixed-income investments trading at a negative interest rate, investors may be willing to continue to purchase such investments for a number of reasons including, but not limited to, price insensitivity, arbitrage opportunities across fixed-income markets or rules-based investment strategies. If negative interest rates become more prevalent in the market, it is expected that investors will seek to reallocate assets to other income-producing assets such as investment grade and high-yield debt instruments, or equity investments that pay a dividend. This increased demand for higher yielding assets may cause the price of such instruments to rise while triggering a corresponding decrease in yield and the value of debt instruments over time.

Russian Securities Risk

The United States and the EU have imposed economic sanctions against companies in certain sectors of the Russian economy, including, but not limited to: financial services, energy, metals and mining, engineering, and defense and defense-related materials. These sanctions could impair a Fund’s ability to continue to invest in Russian issuers. For example, the Fund may be prohibited from investing in securities issued by companies subject to such sanctions. In addition, retaliatory measures by the Russian government in response to such sanctions may result in a freeze of Russian assets held by the Fund, thereby prohibiting the Fund from selling or otherwise transacting in these investments. In such circumstances, the Fund might be forced to liquidate non-restricted assets in order to satisfy shareholder redemptions. Such liquidation of Fund assets might also result in the Fund receiving substantially lower prices for its portfolio securities.

Greater China Region Risk

Investments in the Greater China region are subject to special risks, such as less developed or less efficient trading markets, restrictions on monetary repatriation and possible seizure, nationalization or expropriation of assets. Investments in Taiwan could be adversely affected by its political and economic relationship with China. In addition, the willingness of the Chinese government to support the Chinese and Hong Kong economies and markets is uncertain,

and changes in government policy could significantly affect the markets in both Hong Kong and China. For example, a government may restrict investment in companies or industries considered important to national interests, or intervene in the financial markets, such as by imposing trading restrictions, or banning or curtailing short selling. A small number of companies and industries may represent a relatively large portion of the Greater China market. Consequently, a Fund may experience greater price volatility and significantly lower liquidity than a portfolio invested solely in equity securities of U.S. issuers. These companies and industries also may be subject to greater sensitivity to adverse political, economic or regulatory developments generally affecting the market (see “Risk Factors – Foreign Securities”).

Hong Kong Stock Connect Program (“Stock Connect”) Risk

A Fund may invest in eligible renminbi-denominated class A shares of equity securities that are listed and traded on certain Chinese stock exchanges (“China A-Shares”) through Stock Connect. Trading in China A-Shares through Stock Connect is subject to certain risks. A Fund’s investment in China A-Shares may only be traded through Stock Connect and is not otherwise transferable. The list of eligible China A-Shares may change from time to time. When a China A-Shares issue is recalled from the scope of securities eligible for trading through Stock Connect, the Fund may only sell, but not buy, the securities, which may adversely affect the Fund’s investment strategy.

While Stock Connect is not subject to individual investment quotas, daily and aggregate investment quotas apply to all Stock Connect participants, which may restrict or preclude a Fund’s ability to invest in China A-Shares. For example, these quota limitations require that buy orders for China A-Shares be rejected once the remaining balance of the relevant quota drops to zero or the daily quota is exceeded (although the Fund will be permitted to sell China A-Shares regardless of the quota balance). These limitations may restrict a Fund from investing in China A-Shares on a timely basis, which could affect the Fund’s ability to effectively pursue its investment strategy. Investment quotas are also subject to change.

Chinese regulations prohibit over-selling of China A-Shares. If a Fund intends to sell China A-Shares it holds, it must transfer those securities to the accounts of the Fund’s participant broker before the market opens. As a result, the Fund may not be able to dispose of its holdings of China A-Shares in a timely manner.

Stock Connect also is generally available only on business days when both the exchange on which China A-Shares are offered and the Stock Exchange of Hong Kong (the “SEHK”) are open and when banks in both markets are open on the corresponding settlement days. Therefore, an investment in China A-Shares through Stock Connect may subject the Fund to a risk of price fluctuations on days where the Chinese stock markets are open, but Stock Connect is not operating.

Stock Connect launched on November 17, 2014. Therefore, trading through Stock Connect is subject to trading, clearance and settlement procedures that may continue to develop as the program matures, which could pose risks to a Fund. Additionally, the withholding tax treatment of dividends and capital gains payable to overseas investors may be subject to change.

Stock Connect regulations provide that investors, such as a Fund, enjoy the rights and benefits of equities purchased through Stock Connect. However, the nominee structure under Stock Connect requires that China A-Shares be held through the Hong Kong Securities Clearing Company (the “HKSCC”) as nominee on behalf of investors. While a Fund’s ownership of China A-Shares will be reflected on the books of the custodian’s records, the Fund will only have beneficial rights in such A-Shares. The precise nature and rights of a Fund as the beneficial owner of the SSE equities through the HKSCC as nominee is not well defined under the law of the People’s Republic of China (“PRC”). Although the China Securities Regulatory Commission has issued guidance indicating that participants in Stock Connect will be able to exercise rights of beneficial owners in the PRC, the exact nature and methods of enforcement of the rights and interests of the Fund under PRC law is uncertain. In particular, the courts may consider that the nominee or custodian as registered holder of China A-Shares, has full ownership over the securities rather than the Fund as the underlying beneficial owner. The HKSCC, as nominee holder, does not guarantee the title to China A-Shares held through it and is under no obligation to enforce title or other rights associated with ownership on behalf of beneficial owners. Consequently, title to these securities, or the rights associated with them, such as participation in corporate actions or shareholder meetings, cannot be assured.

While certain aspects of the Stock Connect trading process are subject to Hong Kong law, PRC rules applicable to share ownership will apply. In addition, transactions using Stock Connect are not subject to the Hong Kong investor compensation fund, which means that a Fund will be unable to make monetary claims on the investor compensation

fund that it might otherwise be entitled to with respect to investments in Hong Kong securities. Other risks associated with investments in PRC securities apply fully to China A-Shares purchased through Stock Connect.

China A-Shares traded via Stock Connect are subject to various risks associated with the legal and technical framework of Stock Connect. In the event that the relevant systems fail to function properly, trading in China A-Shares through Stock Connect could be disrupted. In the event of high trade volume or unexpected market conditions, Stock Connect may be available only on a limited basis, if at all. Both the PRC and Hong Kong regulators are permitted, independently of each other, to suspend Stock Connect in response to certain market conditions.

Multinational Companies Risk

To the extent that a Fund invests in the securities of companies with foreign business operations, it may be riskier than funds that focus on companies with primarily U.S. operations. Multinational companies may face certain political and economic risks, such as foreign controls over currency exchange; restrictions on monetary repatriation; possible seizure, nationalization or expropriation of assets; and political, economic or social instability. These risks are greater for companies with significant operations in developing countries.

Natural Disasters and Adverse Weather Conditions

Certain areas of the world historically have been prone to major natural disasters, such as hurricanes, earthquakes, typhoons, flooding, tidal waves, tsunamis, erupting volcanoes, wildfires or droughts, and have been economically sensitive to environmental events. Such disasters, and the resulting damage, could have a severe and negative impact on a Fund’s investment portfolio and, in the longer term, could impair the ability of issuers in which a Fund invests to conduct their businesses in the manner normally conducted. Adverse weather conditions also may have a particularly significant negative effect on issuers in the agricultural sector and on insurance companies that insure against the impact of natural disasters.

Gaming-Tribal Authority Investments

The value of a Fund’s investments in securities issued by gaming companies, including gaming facilities operated by Indian (Native American) tribal authorities, is subject to legislative or regulatory changes, adverse market conditions, and/or increased competition affecting the gaming sector. Securities of gaming companies may be considered speculative, and generally exhibit greater volatility than the overall market. The market value of gaming company securities may fluctuate widely due to unpredictable earnings, due in part to changing consumer tastes and intense competition, strong reaction to technological developments, and the threat of increased government regulation.

Securities issued by Indian tribal authorities are subject to particular risks. Indian tribes enjoy sovereign immunity, which is the legal privilege by which the United States federal, state, and tribal governments cannot be sued without their consent. In order to sue an Indian tribe (or an agency or instrumentality thereof), the tribe must have effectively waived its sovereign immunity with respect to the matter in dispute. Certain Indian tribal authorities have agreed to waive their sovereign immunity in connection with their outstanding debt obligations. Generally, waivers of sovereign immunity have been held to be enforceable against Indian tribes. Nevertheless, if a waiver of sovereign immunity is held to be ineffective, claimants, including investors in Indian tribal authority securities (such as a Fund), could be precluded from judicially enforcing their rights and remedies.

Further, in most commercial disputes with Indian tribes, it may be difficult or impossible to obtain federal court jurisdiction. A commercial dispute may not present a federal question, and an Indian tribe may not be considered a citizen of any state for purposes of establishing diversity jurisdiction. The U.S. Supreme Court has held that jurisdiction in a tribal court must be exhausted before any dispute can be heard in an appropriate federal court. In cases where the jurisdiction of the tribal forum is disputed, the tribal court first must rule as to the limits of its own jurisdiction. Such jurisdictional issues, as well as the general view that Indian tribes are not considered to be subject to ordinary bankruptcy proceedings, may be disadvantageous to holders of obligations issued by Indian tribal authorities, including a Fund.

Investment Companies

Other investment companies include both open- and closed-end investment companies (including single country funds, exchange-traded funds (“ETFs”), and business development companies (“BDCs”). When making such an investment, a Fund will be indirectly exposed to all the risks of such investment companies. In general, the investing Funds will bear a pro rata portion of the other investment company’s fees and expenses.

In addition, the Funds may invest in private investment funds, vehicles, or structures. A Fund also may invest in debt-equity conversion funds, which are funds established to exchange foreign bank debt of countries whose principal repayments are in arrears into a portfolio of listed and unlisted equities, subject to certain repatriation restrictions.

Exchange-Traded Funds. An ETF is a type of investment company shares of which are bought and sold on a securities exchange. An ETF generally represents a fixed portfolio of securities designed to track a particular market index or basket of securities. A fund could purchase shares of an ETF to temporarily gain exposure to a portion of the U.S. or a foreign market while awaiting purchase of underlying securities. The risks of owning an ETF include the risks of owning the underlying securities it is designed to track. In addition, the lack of liquidity in an ETF could result in it being more volatile than the underlying securities and ETFs have management fees that increase their costs. Also, there is a risk that an ETF may fail to closely track the index or basket of securities that it is designed to replicate.

Business Development Companies. A BDC is a less-common type of closed-end investment company that more closely resembles an operating company than a typical investment company. BDCs typically invest in and lend to small- and medium-sized private and certain public companies that may not have access to public equity markets to raise capital. BDCs invest in such diverse industries as health care, chemical and manufacturing, technology and service companies. BDCs generally invest in less mature private companies, which involve greater risk than well-established, publicly traded companies. BDCs are unique in that at least 70% of their investments must be made in private and certain public U.S. businesses, and BDCs are required to make available significant managerial assistance to their portfolio companies. Generally, little public information exists for private and thinly traded companies, and there is a risk that investors may not be able to make a fully informed investment decision. With investments in debt instruments issued by such portfolio companies, there is a risk that the issuer may default on its payments or declare bankruptcy.

Stripped Securities

Stripped securities are the separate income or principal components of a debt security. The risks associated with stripped securities are similar to those of other debt securities, although stripped securities may be more volatile, and the value of certain types of stripped securities may move in the same direction as interest rates. U.S. Treasury securities that have been stripped by a Federal Reserve Bank are obligations issued by the U.S. Treasury.

Mortgage-Backed and Asset-Backed Securities

Mortgage-Backed Securities. Mortgage-backed securities represent participating interests in pools of residential mortgage loans that are guaranteed by the U.S. government, its agencies or instrumentalities. However, the guarantee of these types of securities relates to the principal and interest payments and not the market value of such securities. In addition, the guarantee only relates to the mortgage-backed securities held by a Fund and not the purchase of shares of the Fund.

Mortgage-backed securities are issued by lenders such as mortgage bankers, commercial banks, and savings and loan associations. Such securities differ from conventional debt securities, which provide for the periodic payment of interest in fixed amounts (usually semiannually) with principal payments at maturity or on specified dates. Mortgage-backed securities provide periodic payments that are, in effect, a “pass-through” of the interest and principal payments (including any prepayments) made by the individual borrowers on the pooled mortgage loans. A mortgage-backed security will mature when all the mortgages in the pool mature or are prepaid. Therefore, mortgage-backed securities do not have a fixed maturity, and their expected maturities may vary when interest rates rise or fall.

When interest rates fall, homeowners are more likely to prepay their mortgage loans. An increased rate of prepayments on a Fund’s mortgage-backed securities will result in an unforeseen loss of interest income to the Fund as the Fund may be required to reinvest assets at a lower interest rate. Because prepayments increase when interest rates fall, the prices of mortgage-backed securities do not increase as much as other fixed-income securities when interest rates fall.

When interest rates rise, homeowners are less likely to prepay their mortgage loans. A decreased rate of prepayments lengthens the expected maturity of a mortgage-backed security. Therefore, the prices of mortgage-backed securities may decrease more than prices of other fixed-income securities when interest rates rise.

The yield of mortgage-backed securities is based on the average life of the underlying pool of mortgage loans. The actual life of any particular pool may be shortened by unscheduled or early payments of principal and interest. Principal prepayments may result from the sale of the underlying property or the refinancing or foreclosure of underlying mortgages. The occurrence of prepayments is affected by a wide range of economic, demographic and social factors and, accordingly, it is not possible to accurately predict the average life of a particular pool. The actual prepayment experience of a pool of mortgage loans may cause the yield realized by a Fund to differ from the yield calculated on the basis of the average life of the pool. In addition, if a Fund purchases mortgage-backed securities at a premium, the premium may be lost in the event of early prepayment which may result in a loss to the Fund.

Prepayments tend to increase during periods of falling interest rates and decline during periods of rising interest rates. Monthly interest payments received by a Fund have a compounding effect, which will increase the yield to shareholders as compared to debt obligations that pay interest semiannually. Because of the reinvestment of prepayments of principal at current rates, mortgage-backed securities may be less effective than Treasury bonds of similar maturity at maintaining yields during periods of declining interest rates. Also, although the value of debt securities may increase as interest rates decline, the value of these pass-through type of securities may not increase as much due to their prepayment feature.

Collateralized Mortgage Obligations (“CMOs”). CMOs are mortgage-backed securities issued in separate classes with different stated maturities. As the mortgage pool experiences prepayments, the pool pays off investors in classes with shorter maturities first. By investing in CMOs, a Fund may manage the prepayment risk of mortgage-backed securities. However, prepayments may cause the actual maturity of a CMO to be substantially shorter than its stated maturity.

Asset-Backed Securities . Asset-backed securities include interests in pools of debt securities, commercial or consumer loans, or other receivables. The value of these securities depends on many factors, including changes in interest rates, the availability of information concerning the pool and its structure, the credit quality of the underlying assets, the market’s perception of the servicer of the pool, and any credit enhancement provided. In addition, asset-backed securities have prepayment risks similar to mortgage-backed securities.

Securities Linked to the Real Estate Market

Investing in securities of companies in the real estate industry subjects a Fund to the risks associated with the direct ownership of real estate. These risks include, but are not limited to:

Therefore, if a Fund invests a substantial amount of its assets in securities of companies in the real estate industry, the value of the Fund’s shares may change at different rates compared to the value of shares of a fund with investments in a mix of different industries.

Securities of companies in the real estate industry include real estate investment trusts (“REITs”), including equity REITs and mortgage REITs. Equity REITs may be affected by changes in the value of the underlying property owned by the trusts, while mortgage REITs may be affected by the quality of any credit extended. Further, equity and mortgage REITs are dependent upon management skills and generally may not be diversified. Equity and mortgage REITs also are subject to heavy cash flow dependency, defaults by borrowers and self-liquidations. In addition, equity, mortgage, and hybrid REITs could possibly fail to qualify for tax free pass-through of income under the Code, or to maintain their exemptions from registration under the 1940 Act. The above factors also may adversely affect a borrower’s or a lessee’s ability to meet its obligations to a REIT. In the event of a default by a borrower or lessee, a REIT may experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting its investments.

In addition, even the larger REITs in the industry tend to be small to medium-sized companies in relation to the equity markets as a whole. See “Small and Medium Size Companies” for a discussion of the risks associated with investments in these companies.

Industry or Sector Investing

When a Fund invests a substantial portion of its assets in a particular industry or sector of the economy, the Fund’s investments are not as varied as the investments of most funds and are far less varied than the broad securities markets. As a result, the Fund’s performance tends to be more volatile than other funds, and the values of the Fund’s investments tend to go up and down more rapidly. In addition, a Fund that invests significantly in a particular industry or sector is particularly susceptible to the impact of market, economic, regulatory and others factors affecting that industry or sector.

Consumer Discretionary. The consumer discretionary sector may be affected by fluctuations in supply and demand and may also be adversely affected by changes in consumer spending as a result of world events, political and economic conditions, commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources and labor relations.

Consumer Staples. Companies in the consumer staples sector may be affected by general economic conditions, commodity production and pricing, consumer confidence and spending, consumer preferences, interest rates, product cycles, marketing, competition, and government regulation. Other risks include changes in global economic, environmental and political events, and the depletion of resources. Companies in the consumer staples sector may also be negatively impacted by government regulations affecting their products. For example, government regulations may affect the permissibility of using various food additives and production methods of companies that make food products, which could affect company profitability. Tobacco companies, in particular, may be adversely affected by new laws, regulations and litigation. Companies in the consumer staples sector may also be subject to risks relating to the supply of, demand for, and prices of raw materials. The prices of raw materials fluctuate in response to a number of factors, including, changes in exchange rates, import and export controls, changes in international agricultural and trading policies, and seasonal and weather conditions, among others. In addition, the success of food, beverage, household and personal product companies, in particular, may be strongly affected by unpredictable factors, such as, demographics, consumer spending, and product trends.

Energy. Companies in the energy sector may be affected by energy prices, supply and demand fluctuations including in energy fuels, energy conservation, liabilities arising from government or civil actions, environmental and other government regulations, and geopolitical events including political instability and war. The market value of companies in the local energy sector is heavily impacted by the levels and stability of global energy prices, energy conservation efforts, the success of exploration projects, exchange rates, interest rates, economic conditions, tax and other government regulations, increased competition and technological advances, as well as other factors. Companies in this sector may be subject to extensive government regulation and contractual fixed pricing, which may increase the cost of

doing business and limit these companies’ profits. A large part of the returns of these companies depends on few customers, including governmental entities and utilities. As a result, governmental budget constraints may have a significant negative effect on the stock prices of energy sector companies. Energy companies may also operate in, or engage in, transactions involving countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. As a result, securities of companies in the energy field are subject to quick price and supply fluctuations caused by events relating to international politics. Other risks include liability from accidents resulting in injury or loss of life or property, pollution or other environmental problems, equipment malfunctions or mishandling of materials and a risk of loss from terrorism, political strife and natural disasters. Energy companies can also be heavily affected by the supply of, and demand for, their specific product or service and for energy products in general, and government subsidization. Energy companies may have high levels of debt and may be more likely to restructure their businesses if there are downturns in energy markets or the economy as a whole.

Financial Services. A Fund investing principally in securities of financial services companies is particularly vulnerable to events affecting that industry. Financial services companies include commercial and industrial banks, savings and loan associations and their holding companies, consumer and industrial finance companies, diversified financial services companies, investment banking, securities brokerage and investment advisory companies, leasing companies and insurance companies. These companies are all subject to extensive regulation, rapid business changes, volatile performance dependent upon the availability and cost of capital, prevailing interest rates and significant competition. General economic conditions significantly affect these companies. Credit and other losses resulting from the financial difficulty of borrowers or other third parties have a potentially adverse effect on companies in this industry. Investment banking, securities brokerage and investment advisory companies are particularly subject to government regulation and the risks inherent in securities trading and underwriting activities.

Banking . Commercial banks (including “money center” regional and community banks), savings and loan associations and holding companies of the foregoing are especially subject to adverse effects of volatile interest rates, concentrations of loans in particular industries (such as real estate or energy) and significant competition. The profitability of these businesses is to a significant degree dependent upon the availability and cost of capital funds. Economic conditions in the real estate market may have a particularly strong effect on certain banks and savings associations. Commercial banks and savings associations are subject to extensive federal and, in many instances, state regulation. Neither such extensive regulation nor the federal insurance of deposits ensures the solvency or profitability of companies in this industry, and there is no assurance against losses in securities issued by such companies.

Insurance. Insurance companies are particularly subject to government regulation and rate setting, potential anti-trust and tax law changes, and industry-wide pricing and competition cycles. Property and casualty insurance companies also may be affected by weather and other catastrophes. Life and health insurance companies may be affected by mortality and morbidity rates, including the effects of epidemics. Individual insurance companies may be exposed to reserve inadequacies, problems in investment portfolios (for example, due to real estate or “junk” bond holdings) and failures of reinsurance carriers.

Health Sciences. Companies in this sector are subject to the additional risks of increased competition within the health care industry, changes in legislation or government regulations, reductions in government funding, product liability or other litigation and the obsolescence of popular products. The prices of the securities of health sciences companies may fluctuate widely due to government regulation and approval of their products and services, which may have a significant effect on their price and availability. In addition, the types of products or services produced or provided by these companies may quickly become obsolete. Moreover, liability for products that are later alleged to be harmful or unsafe may be substantial and may have a significant impact on a company’s market value or share price.

Industrials. Companies in the industrials sector may be affected by general economic conditions, commodity production and pricing, supply and demand fluctuations, environmental and other government regulations, geopolitical events, interest rates, insurance costs, technological developments, liabilities arising from governmental or civil actions, labor relations, import controls and government spending. The value of securities issued by companies in the industrials sector may also be adversely affected by supply and demand related to their specific products or services and industrials sector products in general, as well as liability for environmental damage and product liability claims and government regulations. For example, the products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Certain companies within this sector, particularly aerospace and defense companies, may be heavily affected by government spending policies because

companies involved in this industry rely, to a significant extent, on government demand for their products and services, and, therefore, the financial condition of, and investor interest in, these companies are significantly influenced by governmental defense spending policies, which are typically under pressure from efforts to control the U.S. (and other) government budgets. In addition, securities of industrials companies in transportation may be cyclical and have occasional sharp price movements which may result from economic changes, fuel prices, labor relations and insurance costs, and transportation companies in certain countries may also be subject to significant government regulation and oversight, which may adversely affect their businesses.

Internet-Related Investments. The value of companies engaged in Internet-related activities, which is a developing industry, is particularly vulnerable to: (a) rapidly changing technology; (b) extensive government regulation; and (c) relatively high risk of obsolescence caused by scientific and technological advances. In addition, companies engaged in Internet-related activities are difficult to value and many have high share prices relative to their earnings which they may not be able to maintain over the long-term. Moreover, many Internet companies are not yet profitable and will need additional financing to continue their operations. There is no guarantee that such financing will be available when needed. Since many Internet companies are start-up companies, the risks associated with investing in small companies are heightened for these companies. A Fund that invests a significant portion of its assets in Internet-related companies should be considered extremely risky even as compared to other funds that invest primarily in small company securities.

Materials. Companies in the materials sector may be affected by general economic conditions, commodity production and prices, consumer preferences, interest rates, exchange rates, product cycles, marketing, competition, resource depletion, and environmental, import/export and other government regulations. Other risks may include liabilities for environmental damage and general civil liabilities, and mandated expenditures for safety and pollution control. The materials sector may also be affected by economic cycles, technological progress, and labor relations. At times, worldwide production of industrial materials has been greater than demand as a result of over-building or economic downturns, leading to poor investment returns or losses. These risks are heightened for companies in the materials sector located in foreign markets.

Natural Resources. A Fund’s investments in natural resources companies are especially affected by variations in the commodities markets (which may be due to market events, regulatory developments or other factors that such Fund cannot control) and these companies may lack the resources and the broad business lines to weather hard times. Natural resources companies can be significantly affected by events relating to international political developments, energy conservation, the success of exploration projects, commodity prices, and tax and government regulations.

Technology. Technology companies rely heavily on technological advances and face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Shortening of product cycle and manufacturing capacity increases may subject technology companies to aggressive pricing. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face product obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Technology companies may not successfully introduce new products, develop and maintain a loyal customer base or achieve general market acceptance for their products.

Stocks of technology companies, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Companies in the technology sector are also heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect the profitability of these companies. Technology companies engaged in manufacturing, such as semiconductor companies, often operate internationally which could expose them to risks associated with instability and changes in economic and political conditions, foreign currency fluctuations, changes in foreign regulations, competition from subsidized foreign competitors with lower production costs and other risks inherent to international business.

Telecommunications. Companies in the telecommunications sector are subject to the additional risks of rapid obsolescence due to technological advancement or development, lack of standardization or compatibility with existing technologies, an unfavorable regulatory environment, and a dependency on patent and copyright protection. The prices of the securities of companies in the telecommunications sector may fluctuate widely due to both federal and state regulations governing rates of return and services that may be offered, fierce competition for market share, and

competitive challenges in the U.S. from foreign competitors engaged in strategic joint ventures with U.S. companies, and in foreign markets from both U.S. and foreign competitors. In addition, recent industry consolidation trends may lead to increased regulation of telecommunications companies in their primary markets.

Utilities. Companies in the utilities sector may be affected by general economic conditions, supply and demand, financing and operating costs, rate caps, interest rates, liabilities arising from governmental or civil actions, consumer confidence and spending, competition, technological progress, energy prices, resource conservation and depletion, man-made or natural disasters, geopolitical events, and environmental and other government regulations. The value of securities issued by companies in the utilities sector may be negatively impacted by variations in exchange rates, domestic and international competition, energy conservation and governmental limitations on rates charged to customers. Although rate changes of a regulated utility usually vary in approximate correlation with financing costs, due to political and regulatory factors rate changes usually happen only after a delay after the changes in financing costs. Deregulation may subject utility companies to increased competition and can negatively affect their profitability as it permits utility companies to diversify outside of their original geographic regions and customary lines of business, causing them to engage in more uncertain ventures. Deregulation can also eliminate restrictions on the profits of certain utility companies, but can simultaneously expose these companies to an increased risk of loss. Although opportunities may permit certain utility companies to earn more than their traditional regulated rates of return, companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction projects during periods of inflation or unsettled capital markets. Utility companies may also be subject to increased costs because of the effects of man-made or natural disasters. Current and future regulations or legislation can make it more difficult for utility companies to operate profitably. Government regulators monitor and control utility revenues and costs, and thus may restrict utility profits. There is no assurance that regulatory authorities will grant rate increases in the future, or that those increases will be adequate to permit the payment of dividends on stocks issued by a utility company. Because utility companies are faced with the same obstacles, issues and regulatory burdens, their securities may react similarly and more in unison to these or other market conditions.

Initial Public Offerings (“IPOs”)

IPOs may have a magnified impact on the performance of a Fund with a small asset base. The impact of IPOs on a Fund’s performance likely will decrease as the Fund’s asset size increases, which could reduce the Fund’s returns. IPOs may not be consistently available to a Fund for investment, particularly as the Fund’s asset base grows. IPO shares frequently are volatile in price due to the absence of a prior public market, the small number of shares available for trading and limited information about the issuer. Therefore, a Fund may hold IPO shares for a very short period of time. This may increase the turnover of a Fund and may lead to increased expenses for the Fund, such as commissions and transaction costs. In addition, IPO shares can experience an immediate drop in value if the demand for the securities does not continue to support the offering price.

Privately Held and Newly Public Companies

Investments in the stocks of privately held companies and newly public companies involve greater risks than investments in stocks of companies that have traded publicly on an exchange for extended time periods. Investments in such companies are less liquid and may be difficult to value. There may be significantly less information available about these companies’ business models, quality of management, earnings growth potential, and other criteria used to evaluate their investment prospects. The extent (if at all) to which securities of privately held companies or newly public companies may be sold without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Funds that invest in securities of privately held companies tend to have a greater exposure to liquidity risk than Funds that do not invest in securities of privately held companies.

U.S. Government Securities

U.S. government securities include securities issued or guaranteed by the U.S. government or by an agency or instrumentality of the U.S. government. Not all U.S. government securities are backed by the full faith and credit of the United States. Some are supported only by the credit of the issuing agency or instrumentality, which depends entirely on its own resources to repay the debt. U.S. government securities that are backed by the full faith and credit

of the United States include U.S. Treasuries and mortgage-backed securities guaranteed by GNMA. Securities that are only supported by the credit of the issuing agency or instrumentality include those issued by Fannie Mae, the FHLBs and Freddie Mac.

High Yield (High Risk) Securities

General. A Fund may invest in high yield (high risk) securities, consistent with its investment objectives and policies. High yield (high risk) securities (also known as “junk bonds”) are those rated below investment grade and comparable unrated securities. These securities offer yields that fluctuate over time, but generally are superior to the yields offered by higher-rated securities. However, securities rated below investment grade also have greater risks than higher-rated securities as described below.

Interest Rate Risk. To the extent that a Fund invests in fixed-income securities, the NAV of the Fund’s shares can be expected to change as general levels of interest rates fluctuate. However, the market values of securities rated below investment grade (and comparable unrated securities) tend to react less to fluctuations in interest rate levels than do those of higher-rated securities. Except to the extent that values are affected independently by other factors (such as developments relating to a specific issuer) when interest rates decline, the value of a fixed-income fund generally rise. Conversely, when interest rates rise, the value of a fixed-income fund will decline.

Liquidity. The secondary markets for high yield corporate and sovereign debt securities are not as liquid as the secondary markets for investment grade securities. The secondary markets for high yield debt securities are concentrated in relatively few market makers and participants are mostly institutional investors. In addition, the trading volume for high yield debt securities is generally lower than for investment grade securities. Furthermore, the secondary markets could contract under adverse market or economic conditions independent of any specific adverse changes in the condition of a particular issuer.

These factors may have an adverse effect on the ability of Funds investing in high yield securities to dispose of particular portfolio investments. These factors also may limit Funds that invest in high yield securities from obtaining accurate market quotations to value securities and calculate NAV. If a Fund investing in high yield debt securities is not able to obtain precise or accurate market quotations for a particular security, it will be more difficult for the subadvisor to value the Fund’s investments.

Less liquid secondary markets also may affect a Fund’s ability to sell securities at their fair value. Each Fund may invest in illiquid securities, subject to certain restrictions (see “Additional Investment Policies – Illiquid Securities”). These securities may be more difficult to value and to sell at fair value. If the secondary markets for high yield debt securities are affected by adverse economic conditions, the proportion of a Fund’s assets invested in illiquid securities may increase.

Below-Investment Grade Corporate Debt Securities. While the market values of securities rated below investment grade (and comparable unrated securities) tend to react less to fluctuations in interest rate levels than do those of higher-rated securities, the market values of below-investment grade corporate debt securities tend to be more sensitive to individual corporate developments and changes in economic conditions than higher-rated securities.

In addition, these securities generally present a higher degree of credit risk. Issuers of these securities are often highly leveraged and may not have more traditional methods of financing available to them. Therefore, their ability to service their debt obligations during an economic downturn or during sustained periods of rising interest rates may be impaired. The risk of loss due to default by such issuers is significantly greater than with investment grade securities because such securities generally are unsecured and frequently are subordinated to the prior payment of senior indebtedness.

Below-Investment Grade Foreign Sovereign Debt Securities. Investing in below-investment grade foreign sovereign debt securities will expose a Fund to the consequences of political, social or economic changes in the developing and emerging market countries that issue the securities. The ability and willingness of sovereign obligors in these countries to pay principal and interest on such debt when due may depend on general economic and political conditions within the relevant country. Developing and emerging market countries have historically experienced (and

may continue to experience) high inflation and interest rates, exchange rate trade difficulties, extreme poverty and unemployment. Many of these countries also are characterized by political uncertainty or instability.

The ability of a foreign sovereign obligor to make timely payments on its external debt obligations also will be strongly influenced by:

Obligor’s Balance of Payments. A country whose exports are concentrated in a few commodities or whose economy depends on certain strategic imports could be vulnerable to fluctuations in international prices of these commodities or imports. To the extent that a country receives payment for its exports in currencies other than dollars, its ability to make debt payments denominated in dollars could be adversely affected.

Obligor’s Access to International Credits and Investments. If a foreign sovereign obligor cannot generate sufficient earnings from foreign trade to service its external debt, it may need to depend on continuing loans and aid from foreign governments, commercial banks, and multilateral organizations, and inflows of foreign investment. The commitment on the part of these entities to make such disbursements may be conditioned on the government’s implementation of economic reforms and/or economic performance and the timely service of its obligations. Failure in any of these efforts may result in the cancellation of these third parties’ lending commitments, thereby further impairing the obligor’s ability or willingness to service its debts on time.

Obligor’s Fluctuations in Interest Rates. The cost of servicing external debt is generally adversely affected by rising international interest rates since many external debt obligations bear interest at rates that are adjusted based upon international interest rates.

Obligor’s Foreign Reserves. The ability to service external debt also will depend on the level of the relevant government’s international currency reserves and its access to foreign exchange. Currency devaluations may affect the ability of a sovereign obligor to obtain sufficient foreign exchange to service its external debt.

The Consequences of a Default. As a result of the previously listed factors, a governmental obligor may default on its obligations. If a default occurs, a Fund holding foreign sovereign debt securities may have limited legal recourse against the issuer and/or guarantor. Remedies must, in some cases, be pursued in the courts of the defaulting party itself, and the ability of the holder of the foreign sovereign debt securities to obtain recourse may be subject to the political climate in the relevant country. In addition, no assurance can be given that the holders of commercial bank debt will not contest payments to the holders of other foreign sovereign debt obligations in the event of default under their commercial bank loan agreements.

Sovereign obligors in developing and emerging countries are among the world’s largest debtors to commercial banks, other governments, international financial organizations and other financial institutions. These obligors have in the past experienced substantial difficulties in servicing their external debt obligations. This difficulty has led to defaults on certain obligations and the restructuring of certain indebtedness. Restructuring arrangements have included, among other things:

Holders of certain foreign sovereign debt securities may be requested to participate in the restructuring of such obligations and to extend further loans to their issuers. There can be no assurance that the Brady Bonds and other foreign sovereign debt securities in which a Fund may invest will not be subject to similar restructuring arrangements or to requests for new credit that may adversely affect the Fund’s holdings. Furthermore, certain participants in the

secondary market for such debt may be directly involved in negotiating the terms of these arrangements and may therefore have access to information not available to other market participants.

Securities in the Lowest Rating Categories. Certain debt securities in which a Fund may invest may have (or be considered comparable to securities having) the lowest ratings for non-subordinated debt instruments (e.g., securities rated “Caa” or lower by Moody’s or “CCC” or lower by S&P or Fitch). These securities are considered to have the following characteristics:

Accordingly, it is possible that these types of characteristics could, in certain instances, reduce the value of securities held by a Fund with a commensurate effect on the value of the Fund’s shares.

REGULATION OF COMMODITY INTERESTS

The CFTC has adopted regulations that subject registered investment companies and/or their investment advisors to regulation by the CFTC if the registered investment company invests more than a prescribed level of its NAV in commodity futures, options on commodities or commodity futures, swaps, or other financial instruments regulated under the CEA (“commodity interests”), or if the registered investment company markets itself as providing investment exposure to such commodity interests. The Advisor is registered as a CPO under the CEA and is a National Futures Association member firm; however, the Advisor does not act in the capacity of a registered CPO with respect to the Funds.

Although the Advisor is a registered CPO, the Advisor has claimed an exemption from CPO registration pursuant to CFTC Rule 4.5 with respect to each Fund. To remain eligible for this exemption, each of the Funds must comply with certain limitations, including limits on trading in commodity interests, and restrictions on the manner in which the Fund markets its commodity interests trading activities. These limitations may restrict a Fund’s ability to pursue its investment strategy, increase the costs of implementing its strategy, increase its expenses and/or adversely affect its total return.

HEDGING AND OTHER STRATEGIC TRANSACTIONS

Hedging refers to protecting against possible changes in the market value of securities or other assets that a Fund already owns or plans to buy, or protecting unrealized gains in a Fund. These strategies also may be used to gain exposure to a particular market. The hedging and other strategic transactions that may be used by a Fund, but only if and to the extent such transactions are consistent with its investment objective and policies, are described below:

Hedging and other strategic transactions may be used for the following purposes:

To the extent that a Fund uses a hedging or another strategic transaction to gain, shift or manage exposure to a particular geographic region, market, industry, issuer, security, currency, or other asset, the Fund will be exposed to the risks of investing in that asset as well as the risks inherent in the specific hedging or other strategic transaction used to gain such exposure.

For purposes of determining compliance with a Fund’s investment policies, strategies and restrictions, that Fund will generally consider the market value of derivative instruments, unless the nature of the derivative instrument warrants the use of the instrument’s notional value to more accurately reflect the economic exposure represented by the derivative position.

Because of the uncertainties under federal tax laws as to whether income from commodity-linked derivative instruments and certain other instruments would constitute “qualifying income” to a RIC, no Fund is permitted to invest in such instruments unless the subadvisor obtains prior written approval from the Trust’s Chief Compliance Officer (the “CCO”). The CCO, as a member of the Advisor’s Complex Securities Committee, evaluates with the committee the appropriateness of the investment.

General Characteristics of Options

Put options and call options typically have similar structural characteristics and operational mechanics regardless of the underlying instrument on which they are purchased or sold. Many hedging and other strategic transactions involving options require segregation of portfolio assets in special accounts, as described under “Use of Segregated and Other Special Accounts.”

Put Options. A put option gives the purchaser of the option, upon payment of a premium, the right to sell (and the writer the obligation to buy) the underlying security, commodity, index, currency or other instrument at the exercise price. A Fund’s purchase of a put option on a security, for example, might be designed to protect its holdings in the underlying instrument (or, in some cases, a similar instrument) against a substantial decline in the market value of such instrument by giving a Fund the right to sell the instrument at the option exercise price.

If, and to the extent authorized to do so, a Fund may, for various purposes, purchase and sell put options on securities (whether or not it holds the securities in its portfolio) and on securities indices, currencies, and futures contracts.

Risk of Selling Put Options. In selling put options, a Fund faces the risk that it may be required to buy the underlying security at a disadvantageous price above the market price.

Call Options. A call option, upon payment of a premium, gives the purchaser of the option the right to buy (and the seller the obligation to sell) the underlying instrument at the exercise price. A Fund’s purchase of a call option on an underlying instrument might be intended to protect the Fund against an increase in the price of the underlying instrument that it intends to purchase in the future by fixing the price at which it may purchase the instrument. An “American” style put or call option may be exercised at any time during the option period, whereas a “European” style put or call option may be exercised only upon expiration or during a fixed period prior to expiration. If and to the extent authorized to do so, a Fund may purchase and sell call options on securities (whether or not it holds the securities).

Partial Hedge or Income to a Fund. If a Fund sells a call option, the premium that it receives may serve as a partial hedge, to the extent of the option premium, against a decrease in the value of the underlying securities or instruments held by the Fund or will increase the Fund’s income. Similarly, the sale of put options also can provide gains.

Covering of Options. All call options sold by a Fund must be “covered” (that is, the Fund must own the securities or futures contract subject to the call or must otherwise meet the asset segregation requirements described below for so long as the call is outstanding).

Risk of Selling Call Options. Even though a Fund will receive the option premium to help protect it against loss, a call option sold by a Fund will expose it during the term of the option to possible loss of the opportunity to sell the underlying security or instrument with a gain.

Exchange-Listed Options. Exchange-listed options are issued by a regulated intermediary such as the Options Clearing Corporation (the “OCC”), which guarantees the performance of the obligations of the parties to the options. The discussion below uses the OCC as an example but also is applicable to other similar financial intermediaries.

OCC-issued and exchange-listed options, with certain exceptions, generally settle by physical delivery of the underlying security or currency, although in the future, cash settlement may become available. Index options and Eurodollar instruments (which are described below under “Eurodollar Instruments”) are cash settled for the net amount, if any, by which the option is “in-the-money” at the time the option is exercised. “In-the-money” means the amount by which the value of the underlying instrument exceeds, in the case of a call option, or is less than, in the case of a put option, the exercise price of the option. Frequently, rather than taking or making delivery of the underlying instrument through the process of exercising the option, listed options are closed by entering into offsetting purchase or sale transactions that do not result in ownership of the new option.

A Fund’s ability to close out its position as a purchaser or seller of an OCC-issued or exchange-listed put or call option is dependent, in part, upon the liquidity of the particular option market. Among the possible reasons for the absence of a liquid option market on an exchange are:

The hours of trading for listed options may not coincide with the hours during which the underlying financial instruments are traded. To the extent that the option markets close before the markets for the underlying financial instruments, significant price and rate movements can take place in the underlying markets that would not be reflected in the corresponding option markets.

OTC Options. OTC options are purchased from or sold to counterparties such as securities dealers or financial institutions through direct bilateral agreement with the counterparty. In contrast to exchange-listed options, which generally have standardized terms and performance mechanics, all of the terms of an OTC option, including such terms as method of settlement, term, exercise price, premium, guaranties and security, are determined by negotiation of the parties. It is anticipated that a Fund generally will only enter into OTC options that have cash settlement provisions, although it will not be required to do so.

Unless the parties provide for it, no central clearing or guaranty function is involved in an OTC option. As a result, if a counterparty fails to make or take delivery of the security, currency or other instrument underlying an OTC option it has entered into with a Fund or fails to make a cash settlement payment due in accordance with the terms of that option, the Fund will lose any premium it paid for the option as well as any anticipated benefit of the transaction. Thus, the subadvisor must assess the creditworthiness of each such counterparty or any guarantor or credit

enhancement of the counterparty’s credit to determine the likelihood that the terms of the OTC option will be met. A Fund will enter into OTC option transactions only with U.S. government securities dealers recognized by the Federal Reserve Bank of New York as “primary dealers,” or broker-dealers, domestic or foreign banks, or other financial institutions that are deemed creditworthy by the subadvisor. In the absence of a change in the current position of the SEC’s staff, OTC options purchased by a Fund and the amount of the Fund’s obligation pursuant to an OTC option sold by the Fund (the cost of the sell-back plus the in-the-money amount, if any) or the value of the assets held to cover such options will be deemed illiquid.

Types of Options That May Be Purchased. A Fund may purchase and sell call options on securities indices, currencies, and futures contracts, as well as on Eurodollar instruments that are traded on U.S. and foreign securities exchanges and in the OTC markets.

Each Fund reserves the right to invest in options on instruments and indices that may be developed in the future to the extent consistent with applicable law, its investment objective and the restrictions set forth herein.

General Characteristics of Futures Contracts and Options on Futures Contracts

A Fund may trade financial futures contracts (including stock index futures contracts which are described below) or purchase or sell put and call options on those contracts for the following purposes:

Futures contracts are generally bought and sold on the commodities exchanges where they are listed with payment of initial and variation margin as described below. The sale of a futures contract creates a firm obligation by a Fund, as seller, to deliver to the buyer the specific type of financial instrument called for in the contract at a specific future time for a specified price (or, with respect to certain instruments, the net cash amount). Options on futures contracts are similar to options on securities except that an option on a futures contract gives the purchaser the right, in return for the premium paid, to assume a position in a futures contract and obligates the seller to deliver that position.

With respect to futures contracts that are not legally required to “cash settle,” a Fund may cover the open position by setting aside or earmarking liquid assets in an amount equal to the market value of the futures contract. With respect to futures that are required to “cash settle,” such as Eurodollar, UK 90 day and Euribor futures; however, a Fund is permitted to set aside or earmark liquid assets in an amount equal to the Fund’s daily marked to market (net) obligation, if any, (in other words, the Fund’s daily net liability, if any) rather than the market value of the futures contract. By setting aside assets equal to only its net obligation under cash-settled futures contracts, a Fund will have the ability to employ such futures contracts to a greater extent than if the Fund were required to segregate assets equal to the full market value of the futures contract.

A Fund will engage in transactions in futures contracts and related options only to the extent such transactions are consistent with the requirements of the Code in order to maintain its qualification as a RIC for federal income tax purposes.

Margin. Maintaining a futures contract or selling an option on a futures contract will typically require a Fund to deposit with a financial intermediary, as security for its obligations, an amount of cash or other specified assets (“initial margin”) that initially is from 1% to 10% of the face amount of the contract (but may be higher in some circumstances). Additional cash or assets (“variation margin”) may be required to be deposited thereafter daily as the mark-to-market value of the futures contract fluctuates. The purchase of an option on a financial futures contract involves payment of a premium for the option without any further obligation on the part of a Fund. If a Fund exercises an option on a futures contract it will be obligated to post initial margin (and potentially variation margin) for the resulting futures position just as it would for any futures position.

Settlement. Futures contracts and options thereon are generally settled by entering into an offsetting transaction, but no assurance can be given that a position can be offset prior to settlement or that delivery will occur.

Value of Futures Contracts Sold by a Fund. The value of all futures contracts sold by a Fund (adjusted for the historical volatility relationship between such Fund and the contracts) will not exceed the total market value of the Fund’s assets.

Futures contracts may be based on various securities, securities indices and other financial instruments and indices. Futures contracts also may be based on foreign currencies. All futures contracts entered into by each Fund are traded on U.S. or foreign exchanges or boards of trade.

If and to the extent that a Fund is using futures and related options for hedging purposes, futures contracts will be sold to protect against a decline in the price of securities (or the currency in which they are quoted or denominated) that the Fund owns or futures contracts will be purchased to protect the Fund against an increase in the price of securities (or the currency in which they are quoted or denominated) it intends to purchase. Prior to any such purchase, a Fund will determine that the price fluctuations in any futures contracts and options on futures used for hedging purposes are substantially related to price fluctuations in securities held by the Fund or securities or instruments that it expects to purchase. As evidence of its hedging intent, each Fund expects that on 75% or more of the occasions on which it takes a long futures or option position (involving the purchase of futures contracts), the Fund will have purchased, or will be in the process of purchasing, equivalent amounts of related securities (or assets of the Fund denominated in the related currency) in the cash market at the time when the futures or option position is closed out. However, in particular cases, when it is economically advantageous for a Fund to do so, a long futures position may be terminated or an option may expire without the corresponding purchase of securities or other assets. Although under some circumstances prices of securities in a Fund’s portfolio may be more or less volatile than prices of such futures contracts, the subadvisor will attempt to estimate the extent of this volatility difference based on historical patterns and compensate for any differential by having the Fund enter into a greater or lesser number of futures contracts or by attempting to achieve only a partial hedge against price changes affecting the Fund’s portfolio securities.

If and to the extent that a Fund engages in nonhedging transactions in futures contracts and options on futures, the aggregate initial margin and premiums required to establish these nonhedging positions will not exceed 5% of the net asset value of the Fund’s portfolio after taking into account unrealized profits and losses on any such positions and excluding the amount by which such options were in-the-money at the time of purchase.

Stock Index Futures

Definition. A stock index futures contract (an “Index Future”) is a contract to buy a certain number of units of the relevant index at a specified future date at a price agreed upon when the contract is made. A unit is the value at a given time of the relevant index.

Uses of Index Futures. Below are some examples of how a Fund may use Index Futures:

Hedging and other strategic transactions involving futures contracts, options on futures contracts and swaps will be purchased, sold or entered into primarily for bona fide hedging, risk management (including duration management) or appropriate portfolio management purposes, including gaining exposure to a particular securities market.

Options on Securities Indices and Other Financial Indices (“Options on Financial Indices”)

A Fund may purchase and sell call and put options on securities indices and other financial indices (“Options on Financial Indices”). In so doing, a Fund may achieve many of the same objectives it would achieve through the sale or purchase of options on individual securities or other instruments.

Description of Options on Financial Indices. Options on Financial Indices are similar to options on a security or other instrument except that, rather than settling by physical delivery of the underlying instrument, Options on Financial Indices settle by cash settlement. Cash settlement means that the holder has the right to receive, upon exercise of the option, an amount of cash if the closing level of the index upon which the option is based exceeds, in the case of a call (or is less than, in the case of a put) the exercise price of the option. This amount of cash is equal to the excess of the closing price of the index over the exercise price of the option, which also may be multiplied by a formula value. The seller of the option is obligated to make delivery of this amount. The gain or loss on an option on an index depends on price movements in the instruments comprising the market or other composite on which the underlying index is based, rather than price movements in individual securities, as is the case for options on securities. In the case of an OTC option, physical delivery may be used instead of cash settlement. By purchasing or selling Options on Financial Indices, a Fund may achieve many of the same objectives it would achieve through the sale or purchase of options on individual securities or other instruments.

Yield Curve Options

A Fund also may enter into options on the “spread,” or yield differential, between two fixed-income securities, in transactions referred to as “yield curve” options. In contrast to other types of options, a yield curve option is based on the difference between the yields of designated securities, rather than the prices of the individual securities, and is settled through cash payments. Accordingly, a yield curve option is profitable to the holder if this differential widens (in the case of a call) or narrows (in the case of a put), regardless of whether the yields of the underlying securities increase or decrease.

Yield curve options may be used for the same purposes as other options on securities. Specifically, a Fund may purchase or write such options for hedging purposes. For example, a Fund may purchase a call option on the yield spread between two securities, if it owns one of the securities and anticipates purchasing the other security and wants to hedge against an adverse change in the yield spread between the two securities. A Fund also may purchase or write yield curve options for other than hedging purposes (e.g., in an effort to increase its current income) if, in the judgment of the subadvisor, the Fund will be able to profit from movements in the spread between the yields of the underlying securities. The trading of yield curve options is subject to all of the risks associated with the trading of other types of options. In addition, however, such options present risk of loss even if the yield of one of the underlying securities remains constant, if the spread moves in a direction or to an extent which was not anticipated. Yield curve options written by a Fund will be “covered.” A call (or put) option is covered if a Fund holds another call (or put) option on the spread between the same two securities and owns liquid and unencumbered assets sufficient to cover the Fund’s net liability under the two options. Therefore, a Fund’s liability for such a covered option is generally limited to the difference between the amounts of the Fund’s liability under the option written by the Fund less the value of the option held by it. Yield curve options also may be covered in such other manner as may be in accordance with the requirements of the counterparty with which the option is traded and applicable laws and regulations. Yield curve options are traded over-the-counter.

Currency Transactions

A Fund may engage in currency transactions with counterparties to hedge the value of portfolio securities denominated in particular currencies against fluctuations in relative value, to gain exposure to a currency without purchasing securities denominated in that currency, to facilitate the settlement of equity trades or to exchange one currency for another. If a Fund enters into a currency hedging transaction, the Fund will comply with the asset segregation requirements described below under “Use of Segregated and Other Special Accounts.” Currency transactions include:

A forward currency contract involves a privately negotiated obligation to purchase or sell (with delivery generally required) a specific currency at a future date at a price set at the time of the contract. A currency swap is an agreement to exchange cash flows based on the notional difference among two or more currencies and operates similarly to an interest rate swap, which is described under “Swap Agreements and Options on Swap Agreements.” A Fund may enter into currency transactions only with counterparties that are deemed creditworthy by the subadvisor. Nevertheless, engaging in currency transactions will expose a Fund to counterparty risk.

A Fund’s dealings in forward currency contracts and other currency transactions such as futures contracts, options, options on futures contracts and swaps may be used for hedging and similar purposes, possibly including transaction hedging, position hedging, cross hedging and proxy hedging. A Fund also may use foreign currency options and foreign currency forward contracts to increase exposure to a foreign currency or to shift exposure to foreign currency fluctuation from one country to another or to facilitate the settlement of equity trades. A Fund may elect to hedge less than all of its foreign portfolio positions as deemed appropriate by the subadvisor.

Each Fund also may engage in non-deliverable forward transactions to manage currency risk or to gain exposure to a currency without purchasing securities denominated in that currency. A non-deliverable forward is a transaction that represents an agreement between a Fund and a counterparty (usually a commercial bank) to buy or sell a specified (notional) amount of a particular currency at an agreed-upon foreign exchange rate on an agreed-upon future date. Unlike other currency transactions, there is no physical delivery of the currency on the settlement of a non-deliverable forward transaction. Rather, the Fund and the counterparty agree to net the settlement by making a payment in U.S. dollars or another fully convertible currency that represents any differential between the foreign exchange rate agreed upon at the inceptions of the non-deliverable forward agreement and the actual exchange rate on the agreed-upon future date. Thus, the actual gain or loss of a given non-deliverable forward transaction is calculated by multiplying the transaction’s notional amount by the difference between the agreed-upon forward exchange rate and the actual exchange rate when the transaction is completed.

When a Fund enters into a non-deliverable forward transaction, the Fund will segregate liquid assets in an amount not less than the value of the Fund’s net exposure to such non-deliverable forward transactions. If the additional segregated assets decline in value or the amount of the Fund’s commitment increases because of a change in currency rates, additional cash or securities will be segregated on a daily basis so that the value of the account will equal the amount of the Fund’s commitments under the non-deliverable forward agreement.

Since a Fund generally may only close out a non-deliverable forward with the particular counterparty, there is a risk that the counterparty will default on its obligation to pay under the agreement. If the counterparty defaults, the Fund will have contractual remedies pursuant to the agreement related to the transaction, but there is no assurance that contract counterparties will be able to meet their obligations pursuant to such agreements or that, in the event of a default, the Fund will succeed in pursuing contractual remedies. The Fund thus assumes the risk that it may be delayed or prevented from obtaining payments owed to it pursuant to non-deliverable forward transactions.

In addition, where the currency exchange rates that are the subject of a given non-deliverable forward transaction do not move in the direction or to the extent anticipated, a Fund could sustain losses on the non-deliverable forward transaction. A Fund’s investment in a particular non-deliverable forward transaction will be affected favorably or unfavorably by factors that affect the subject currencies, including economic, political and legal developments that impact the applicable countries, as well as exchange control regulations of the applicable countries. These risks are heightened when a non-deliverable forward transaction involves currencies of emerging market countries because such currencies can be volatile and there is a greater risk that such currencies will be devalued against the U.S. dollar or other currencies.

Transaction Hedging. Transaction hedging involves entering into a currency transaction with respect to specific assets or liabilities of a Fund, which generally will arise in connection with the purchase or sale of portfolio securities or the receipt of income from them.

Position Hedging. Position hedging involves entering into a currency transaction with respect to portfolio securities positions denominated or generally quoted in that currency.

Cross Hedging. A Fund may cross-hedge currencies by entering into transactions to purchase or sell one or more currencies that are expected to increase or decline in value relative to other currencies to which the Fund has or in which the Fund expects to have exposure.

Proxy Hedging. To reduce the effect of currency fluctuations on the value of existing or anticipated holdings of its securities, a Fund also may engage in proxy hedging. Proxy hedging is often used when the currency to which a Fund’s holdings are exposed is generally difficult to hedge or specifically difficult to hedge against the dollar. Proxy hedging entails entering into a forward contract to sell a currency, the changes in the value of which are generally considered to be linked to a currency or currencies in which some or all of a Fund’s securities are or are expected to be denominated, and to buy dollars. The amount of the contract would not exceed the market value of the Fund’s securities denominated in linked currencies.

Combined Transactions

A Fund may enter into multiple transactions, including multiple options transactions, multiple futures transactions, multiple currency transactions (including forward currency contracts), multiple interest rate transactions and any combination of futures, options, currency and interest rate transactions. A combined transaction usually will contain elements of risk that are present in each of its component transactions. Although a Fund normally will enter into combined transactions to reduce risk or otherwise more effectively achieve the desired portfolio management goal, it is possible that the combination will instead increase the risks or hinder achievement of the Fund’s investment objective.

Swap Agreements and Options on Swap Agreements

Among the hedging and other strategic transactions into which a Fund may be authorized to enter are swap transactions, including, but not limited to, swap agreements on interest rates, security or commodity indexes, specific securities and commodities, currency exchange rates, and credit and event-linked swaps. To the extent that a Fund may invest in foreign currency-denominated securities, it also may invest in currency exchange rate swap agreements.

A Fund may enter into swap transactions for any legal purpose consistent with its investment objective and policies, such as to attempt to obtain or preserve a particular return or spread at a lower cost than obtaining a return or spread through purchases and/or sales of instruments in other markets, to protect against currency fluctuations, as a duration management technique, to protect against any increase in the price of securities the Fund anticipates purchasing at a later date, or to gain exposure to certain markets in the most economical way possible.

OTC swap agreements are two-party contracts entered into primarily by institutional investors for periods ranging from a few weeks to one or more years. In a standard “swap” transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments, which may be adjusted for an interest factor. The gross returns to be exchanged or “swapped” between the parties are generally calculated with respect to a “notional amount,” i.e., the return on or increase in value of a particular dollar amount invested at a particular interest rate, in a particular foreign currency, or in a “basket” of securities or commodities representing a particular index. A “quanto” or “differential” swap combines both an interest rate and a currency transaction. Other forms of swap agreements include interest rate caps, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates exceed a specified rate, or “cap”; interest rate floors, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates fall below a specified rate, or “floor”; and interest rate collars, under which a party sells a cap and purchases a floor or vice versa in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels. A Fund may invest in commodity swap agreements. For example, an investment in a commodity swap agreement may involve the exchange of floating-rate interest payments for the total return on a commodity index. In a total return commodity swap, a Fund will receive the price appreciation of a commodity index, a portion of the index, or a single commodity in exchange for paying an agreed-upon fee. If the commodity swap is for one period, a Fund may pay a fixed fee, established at the outset of the swap. However, if the term of the commodity swap is more than one period, with interim swap payments, a Fund may pay an adjustable or floating fee. With a “floating” rate, the fee may be pegged to a base rate, such as LIBOR, and is adjusted each period. Therefore, if interest rates increase over the term of the swap contract, a Fund may be required to pay a higher fee at each swap reset date.

A Fund may enter into options on swap agreements (“Swap Options”). A Swap Option is a contract that gives a counterparty the right (but not the obligation), in return for payment of a premium, to enter into a new swap agreement or to shorten, extend, cancel or otherwise modify an existing swap agreement, at some designated future time on specified terms. A Fund also may write (sell) and purchase put and call Swap Options.

Depending on the terms of the particular agreement, a Fund generally will incur a greater degree of risk when it writes a Swap Option than it will incur when it purchases a Swap Option. When a Fund purchases a swap option, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. However, when a Fund writes a Swap Option, upon exercise of the option the Fund will become obligated according to the terms of the underlying agreement. Most other types of swap agreements entered into by a Fund would calculate the obligations of the parties to the agreement on a “net basis.” Consequently, a Fund’s current obligations (or rights) under a swap agreement generally will be equal only to the net amount to be paid or received under the agreement based on the relative values of the positions held by each party to the agreement (the “net amount”). A Fund’s current obligations under a swap agreement will be accrued daily (offset against any amounts owed to the Fund) and any accrued but unpaid net amounts owed to a swap counterparty will be covered by the segregation or “earmarking” of liquid assets, to avoid any potential leveraging of the Fund’s investments. Obligations under swap agreements so covered will not be construed to be “senior securities” for purposes of a Fund’s investment restriction concerning senior securities.

Whether a Fund’s use of swap agreements or Swap Options will be successful in furthering its investment objective will depend on the subadvisor’s ability to predict correctly whether certain types of investments are likely to produce greater returns than other investments. Because OTC swaps are two-party contracts, and because they may have terms of greater than seven days, they may be considered to be illiquid. Moreover, a Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. A Fund will enter into swap agreements only with counterparties that meet certain standards of creditworthiness. Certain restrictions imposed on a Fund by the Code may limit its ability to use swap agreements. Current regulatory initiatives, described below, and potential future regulation could adversely affect a Fund’s ability to terminate existing swap agreements or to realize amounts to be received under such agreements. A Fund will not enter into a swap agreement with any single party if the net amount owed to the Fund under existing contracts with that party would exceed 5% of the Fund’s total assets.

Swaps are highly specialized instruments that require investment techniques, risk analyses, and tax planning different from those associated with traditional investments. The use of a swap requires an understanding not only of the referenced asset, rate, or index but also of the swap itself, without the benefit of observing the performance of the swap under all possible market conditions. Swap agreements may be subject to liquidity risk, which exists when a particular swap is difficult to purchase or sell. If a swap transaction is particularly large or if the relevant market is illiquid (as is the case with many OTC swaps), it may not be possible to initiate a transaction or liquidate a position at an advantageous time or price, which may result in significant losses. In addition, a swap transaction may be subject to a Fund’s limitation on investments in illiquid securities.

Like most other investments, swap agreements are subject to the risk that the market value of the instrument will change in a way detrimental to a Fund’s interest. A Fund bears the risk that the subadvisor will not accurately forecast future market trends or the values of assets, reference rates, indexes, or other economic factors in establishing swap positions for it. If a subadvisor attempts to use a swap as a hedge against, or as a substitute for, an investment, a Fund will be exposed to the risk that the swap will have or will develop imperfect or no correlation with the investment. This could cause substantial losses for the Fund. While hedging strategies involving swap instruments can reduce the risk of loss, they also can reduce the opportunity for gain or even result in losses by offsetting favorable price movements in other investments.

The swaps market was largely unregulated prior to the enactment of federal legislation known as the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), which was enacted in 2010 in response to turmoil in the financial markets and other market events. Among other things, the Dodd-Frank Act sets forth a new regulatory framework for certain OTC derivatives, such as swaps, in which the Funds may invest. The Dodd-Frank Act requires many swap transactions to be executed on registered exchanges or through swap execution facilities, cleared through a regulated clearinghouse and publicly reported. In addition, many market participants are now regulated as swap dealers or major swap participants and are, or will be, subject to certain minimum capital and margin requirements and business conduct standards. The statutory requirements of the Dodd-Frank Act are being

implemented primarily through rules and regulations adopted by the SEC and/or the CFTC. There is a prescribed phase-in period during which most of the mandated rulemaking and regulations are being implemented, and temporary exemptions from certain rules and regulations have been granted so that current trading practices will not be unduly disrupted during the transition period.

As of the date of this SAI, central clearing is required only for certain market participants trading certain instruments, although central clearing for additional instruments is expected to be implemented by the CFTC until the majority of the swaps market is ultimately subject to central clearing. In addition, as described below, uncleared OTC swaps may be subject to regulatory collateral requirements that could adversely affect a Fund’s ability to enter into swaps in the OTC market. These developments could cause a Fund to terminate new or existing swap agreements, realize amounts to be received under such instruments at an inopportune time, or increase the costs associated with trading derivatives. Until the mandated rulemaking and regulations are implemented completely, it will not be possible to determine the complete impact of the Dodd-Frank Act and related regulations on the Funds. Swap dealers, major market participants and swap counterparties may also experience other new and/or additional regulations, requirements, compliance burdens and associated costs. The legislation and rules promulgated thereunder may exert a negative effect on a Fund’s ability to meet its investment objective, either through limits or requirements imposed on the Fund or its counterparties. The swap market could be disrupted or limited as a result of the legislation, and the new requirements may increase the cost of the Fund’s investments and of doing business, which could adversely affect a Fund’s ability to buy or sell OTC derivatives. The prudential regulators issued final rules that will require banks subject to their supervision to post and collect variation and initial margin in respect of their obligations arising under uncleared swap agreements. In addition, the CFTC adopted similar rules that apply to CFTC-registered swap dealers and major swap participants that are not banks. Such rules generally require the Funds to segregate additional assets in order to meet the new variation and initial margin requirements when they enter into uncleared swap agreements. The variation margin requirements became effective in 2017 and the initial margin requirements are being phased-in through September 2020 based on the average daily aggregate notional amount of covered swaps between swap dealers, swap entities and major swap participants.

In addition, rules adopted by the prudential regulators that are set to be phased-in starting in January 1, 2019, will require certain regulated banks to include in a range of financial contracts, including derivative and short-term funding transactions terms delaying or restricting a counterparty’s default, termination and other rights in the event that the bank and/or its affiliates are subject to certain types of resolution or insolvency proceedings. The regulations could limit a Fund’s ability to exercise a range of cross-default rights if its counterparty, or an affiliate of the counterparty, is subject to bankruptcy or similar proceedings. Such regulations could further negatively impact the Funds’ use of derivatives.

Additional information about certain swap agreements that the Funds may be authorized to utilize is provided below.

Credit default swap agreements (“CDS”). CDS may have as reference obligations one or more securities that are not currently held by a Fund. The protection “buyer” in a CDS is generally obligated to pay the protection “seller” an upfront or a periodic stream of payments over the term of the CDS provided that no credit event, such as a default, on a reference obligation has occurred. If a credit event occurs, the seller generally must pay the buyer the “par value” (full notional value) of the CDS in exchange for an equal face amount of deliverable obligations of the reference entity described in the CDS, or the seller may be required to deliver the related net cash amount, if the CDS is cash settled. A Fund may be authorized to be either the buyer or seller in the transaction. If a Fund is a buyer and no credit event occurs, the Fund may recover nothing if the CDS is held through its termination date. However, if a credit event occurs, the buyer generally may elect to receive the full notional value of the CDS in exchange for an equal face amount of deliverable obligations of the reference entity whose value may have significantly decreased. As a seller, a Fund generally receives an upfront payment or a fixed rate of income throughout the term of the CDS, provided that there is no credit event. As the seller, a Fund would effectively add leverage to the Fund because, in addition to its total net assets, the Fund would be subject to investment exposure on the notional amount of the CDS. If a Fund enters into a CDS, the Fund may be required to report the CDS as a “listed transaction” for tax shelter reporting purposes on the Fund’s federal income tax return. If the IRS were to determine that the CDS is a tax shelter, a Fund could be subject to penalties under the Code.

CDS on index tranches give a Fund, as a seller of credit protection, the opportunity to take on exposures to specific segments of the CDS index default loss distribution. Each tranche has a different sensitivity to credit risk correlations

among entities in the index. One of the main benefits of index tranches is higher liquidity. This has been achieved mainly through standardization, yet it is also due to the liquidity in the single-name CDS and CDS index markets. In contrast, possibly owing to the limited liquidity in the corporate bond market, securities referencing corporate bond indexes have not been traded actively.

CDS involve greater risks than if a Fund had invested in the reference obligation directly since, in addition to general market risks, CDS are subject to illiquidity risk, counterparty risk and credit risk. A Fund will enter into CDS only with counterparties that meet certain standards of creditworthiness. A buyer generally also will lose its investment and recover nothing should no credit event occur and the CDS is held to its termination date. If a credit event were to occur, the value of any deliverable obligation received by the seller, coupled with the upfront or periodic payments previously received, may be less than the full notional value it pays to the buyer, resulting in a loss of value to the seller. A Fund’s obligations under a CDS will be accrued daily (offset against any amounts owing to the Fund). In connection with CDS in which a Fund is the buyer, the Fund will segregate or “earmark” cash or liquid assets, or enter into certain offsetting positions, with a value at least equal to the Fund’s exposure (any accrued but unpaid net amounts owed by the Fund to any counterparty), on a mark-to-market basis. In connection with CDS in which a Fund is the seller, the Fund will segregate or “earmark” cash or liquid assets, or enter into offsetting positions, with a value at least equal to the full notional amount of the CDS. Such segregation or “earmarking” will ensure that the Fund has assets available to satisfy its obligations with respect to the transaction and will limit any potential leveraging of the Fund’s investments. Such segregation or “earmarking” will not limit the Fund’s exposure to loss.

Dividend swap agreements. A dividend swap agreement is a financial instrument where two parties contract to exchange a set of future cash flows at set dates in the future. One party agrees to pay the other the future dividend flow on a stock or basket of stocks in an index, in return for which the other party gives the first call options. Dividend swaps generally are traded OTC rather than on an exchange.

Inflation swap agreements. An inflation swap agreement is a contract in which one party agrees to pay the cumulative percentage increase in a price index ( e.g ., the Consumer Price Index (“CPI”) with respect to CPI swaps) over the term of the swap (with some lag on the inflation index), and the other pays a compounded fixed rate. Inflation swap agreements may be used to protect a Fund’s NAV against an unexpected change in the rate of inflation measured by an inflation index since the value of these agreements is expected to increase if unexpected inflation increases.

Interest rate swap agreements . An interest rate swap agreement involves the exchange of cash flows based on interest rate specifications and a specified principal amount, often a fixed payment for a floating payment that is linked to an interest rate. An interest rate lock specifies a future interest rate to be paid. In an interest rate cap, one party receives payments at the end of each period in which a specified interest rate on a specified principal amount exceeds an agreed-upon rate; conversely, in an interest rate floor, one party may receive payments if a specified interest rate on a specified principal amount falls below an agreed-upon rate. Caps and floors have an effect similar to buying or writing options. Interest rate collars involve selling a cap and purchasing a floor, or vice versa, to protect a Fund against interest rate movements exceeding given minimum or maximum levels.

Total return swap agreements. A total return swap agreement is a contract whereby one party agrees to make a series of payments to another party based on the change in the market value of the assets underlying such contract (which can include a security, commodity, index or baskets thereof) during the specified period. In exchange, the other party to the contract agrees to make a series of payments calculated by reference to an interest rate and/or some other agreed-upon amount (including the change in market value of other underlying assets). A Fund may use total return swaps to gain exposure to an asset without owning it or taking physical custody of it. For example, by investing in total return commodity swaps, a Fund will receive the price appreciation of a commodity, commodity index or portion thereof in exchange for payment of an agreed-upon fee.

Variance swap agreements. Variance swap agreements involve an agreement by two parties to exchange cash flows based on the measured variance (or square of volatility) of a specified underlying asset. One party agrees to exchange a “fixed rate” or strike price payment for the “floating rate” or realized price variance on the underlying asset with respect to the notional amount. At inception, the strike price chosen is generally fixed at a level such that the fair value of the swap is zero. As a result, no money changes hands at the initiation of the contract. At the expiration date, the amount paid by one party to the other is the difference between the realized price variance of the underlying asset and the strike price multiplied by the notional amount. A receiver of the realized price variance would receive a payment when the realized price variance of the underlying asset is greater than the strike price and would make a payment

when that variance is less than the strike price. A payer of the realized price variance would make a payment when the realized price variance of the underlying asset is greater than the strike price and would receive a payment when that variance is less than the strike price. This type of agreement is essentially a forward contract on the future realized price variance of the underlying asset.

Eurodollar Instruments

Eurodollar instruments typically are dollar-denominated futures contracts or options on those contracts that are linked to LIBOR. In addition, foreign currency-denominated instruments are available from time to time. Eurodollar futures contracts enable purchasers to obtain a fixed rate for the lending of funds and sellers to obtain a fixed rate for borrowings. A Fund might use Eurodollar futures contracts and options thereon to hedge against changes in LIBOR, to which many interest rate swaps and fixed-income instruments are linked.

Warrants and Rights

Warrants and rights generally give the holder the right to receive, upon exercise and prior to the expiration date, a security of the issuer at a stated price. Funds typically use warrants and rights in a manner similar to their use of options on securities, as described in “General Characteristics of Options” above and elsewhere in this SAI. Risks associated with the use of warrants and rights are generally similar to risks associated with the use of options. Unlike most options, however, warrants and rights are issued in specific amounts, and warrants generally have longer terms than options. Warrants and rights are not likely to be as liquid as exchange-traded options backed by a recognized clearing agency. In addition, the terms of warrants or rights may limit a Fund’s ability to exercise the warrants or rights at such time, or in such quantities, as the Fund would otherwise wish.

Non-Standard Warrants and Participatory Notes. From time to time, a Fund may use non-standard warrants, including low exercise price warrants or low exercise price options (“LEPOs”), and participatory notes (“P-Notes”) to gain exposure to issuers in certain countries. LEPOs are different from standard warrants in that they do not give their holders the right to receive a security of the issuer upon exercise. Rather, LEPOs pay the holder the difference in price of the underlying security between the date the LEPO was purchased and the date it is sold. P-Notes are a type of equity-linked derivative that generally are traded over-the-counter and constitute general unsecured contractual obligations of the banks, broker-dealers or other financial institutions that issue them. Generally, banks and broker-dealers associated with non-U.S.-based brokerage firms buy securities listed on certain foreign exchanges and then issue P-Notes that are designed to replicate the performance of certain issuers and markets. The performance results of P-Notes will not replicate exactly the performance of the issuers or markets that the notes seek to replicate due to transaction costs and other expenses. The return on a P-Note that is linked to a particular underlying security generally is increased to the extent of any dividends paid in connection with the underlying security. However, the holder of a P-Note typically does not receive voting or other rights as it would if it directly owned the underlying security, and P-Notes present similar risks to investing directly in the underlying security. Additionally, LEPOs and P-Notes entail the same risks as other over-the-counter derivatives. These include the risk that the counterparty or issuer of the LEPO or P-Note may not be able to fulfill its obligations, that the holder and counterparty or issuer may disagree as to the meaning or application of contractual terms, or that the instrument may not perform as expected. See “Principal risks—Counterparty risk” in the applicable Prospectuses and “Risk of Hedging and Other Strategic Transactions” below. Additionally, while LEPOs or P-Notes may be listed on an exchange, there is no guarantee that a liquid market will exist or that the counterparty or issuer of a LEPO or P-Note will be willing to repurchase such instrument when a Fund wishes to sell it.

Risk of Hedging and Other Strategic Transactions

Hedging and other strategic transactions are subject to special risks, including:

Losses resulting from the use of hedging and other strategic transactions will reduce a Fund’s NAV, and possibly income. Losses can be greater than if hedging and other strategic transactions had not been used.

Options and Futures Transactions. Options transactions are subject to the following additional risks:

Futures transactions are subject to the following additional risks:

Although a Fund’s use of futures and options for hedging should tend to minimize the risk of loss due to a decline in the value of the hedged position, it will tend, at the same time, to limit the potential gain that might result from an increase in value.

Currency Hedging. In addition to the general risks of hedging and other strategic transactions described above, currency hedging transactions have the following risks:

Currency Futures Contracts and Options on Currency Futures Contracts. Currency futures contracts are subject to the same risks that apply to the use of futures contracts generally. In addition, settlement of a currency futures contract for the purchase of most currencies must occur at a bank based in the issuing nation. Trading options on currency futures contracts is relatively new, and the ability to establish and close out positions on these options is subject to the maintenance of a liquid market that may not always be available.

Risk Associated with Specific Types of Derivative Debt Securities. Different types of derivative debt securities are subject to different combinations of prepayment, extension and/or interest rate risk. Conventional mortgage pass-through securities and sequential pay CMOs are subject to all of these risks, but typically are not leveraged. Thus, the magnitude of exposure may be less than for more leveraged mortgage-backed securities.

The risk of early prepayments is the primary risk associated with IOs, super floaters, other leveraged floating rate instruments and mortgage-backed securities purchased at a premium to their par value. In some instances, early prepayments may result in a complete loss of investment in certain of these securities. The primary risks associated with certain other derivative debt securities are the potential extension of average life and/or depreciation due to rising interest rates.

Derivative debt securities include floating rate securities based on the Cost of Funds Index (“COFI floaters”), other “lagging rate” floating rate securities, capped floaters, mortgage-backed securities purchased at a discount, leveraged inverse floating rate securities, POs, certain residual or support tranches of CMOs and index amortizing notes. Index amortizing notes are not mortgage-backed securities, but are subject to extension risk resulting from the issuer’s failure to exercise its option to call or redeem the notes before their stated maturity date. Leveraged inverse IOs combine several elements of the mortgage-backed securities described above and present an especially intense combination of prepayment, extension and interest rate risks.

Planned amortization class (“PAC”) and target amortization class (“TAC”) CMO bonds involve less exposure to prepayment, extension and interest rate risk than other mortgage-backed securities, provided that prepayment rates remain within expected prepayment ranges or “collars.” To the extent that prepayment rates remain within these prepayment ranges, the residual or support tranches of PAC and TAC CMOs assume the extra prepayment, extension and interest rate risk associated with the underlying mortgage assets.

Other types of floating rate derivative debt securities present more complex types of interest rate risks. For example, range floaters are subject to the risk that the coupon will be reduced to below market rates if a designated interest rate floats outside of a specified interest rate band or collar. Dual index or yield curve floaters are subject to depreciation in the event of an unfavorable change in the spread between two designated interest rates. X-reset floaters have a coupon that remains fixed for more than one accrual period. Thus, the type of risk involved in these securities depends on the terms of each individual X-reset floater.

Risks of Hedging and Other Strategic Transactions Outside the United States

When conducted outside the United States, hedging and other strategic transactions will not only be subject to the risks described above but also could be adversely affected by:

Use of Segregated and Other Special Accounts

Use of extensive hedging and other strategic transactions by a Fund will require, among other things, that the Fund post collateral with counterparties or clearinghouses and/or segregate cash or other liquid assets with its custodian, or a designated subcustodian, to the extent that the Fund’s obligations are not otherwise “covered” through ownership of the underlying security, financial instrument or currency.

In general, either the full amount of any obligation by a Fund to pay or deliver securities or assets under a transaction or series of transactions must be covered at all times by (a) holding the securities, instruments or currency required to meet the Fund’s obligations under such transactions or series of transactions; or (b) subject to any regulatory restrictions, segregating an amount of cash or other liquid assets at least equal to the current amount of the obligation.

The segregated assets cannot be sold or transferred unless equivalent assets are substituted in their place or it is no longer necessary to segregate them. Some examples of cover requirements are set forth below.

Call Options. A call option on securities written by a Fund will require the Fund to hold the securities subject to the call (or securities convertible into the needed securities without additional consideration) or to segregate cash or other liquid assets sufficient to purchase and deliver the securities if the call is exercised. A call option sold by a Fund on an index will require the Fund to own portfolio securities that correlate with the index or to segregate cash or other liquid assets equal to its obligations under the option.

Put Options. A put option on securities written by a Fund will require the Fund to segregate cash or other liquid assets equal to the exercise price.

OTC Options. OTC options entered into by a Fund, including those on securities, currency, financial instruments or indices, and OTC-issued and exchange-listed index options generally will provide for cash settlement, although the Fund will not be required to do so. As a result, when a Fund sells these instruments it will segregate an amount of cash or other liquid assets equal to its obligations under the options. OTC-issued and exchange-listed options sold by a Fund other than those described above generally settle with physical delivery, and the Fund will segregate an amount of cash or liquid high grade debt securities equal to the full value of the option. OTC options settling with physical delivery or with an election of either physical delivery or cash settlement will be treated the same as other options settling with physical delivery.

Currency Contracts. Except when a Fund enters into a forward contract in connection with the purchase or sale of a security denominated in a foreign currency or for other non-speculative purposes, which requires no segregation, a currency contract that obligates the Fund to buy or sell a foreign currency generally will require the Fund to hold an amount of that currency or liquid securities denominated in that currency equal to the Fund’s obligations or to segregate cash or other liquid assets equal to the amount of the Fund’s obligations.

Futures Contracts and Options on Futures Contracts . In the case of a futures contract or an option on a futures contract, a Fund must deposit initial margin and, in some instances, daily variation margin, in addition to segregating assets sufficient to meet its obligations under the contract. These assets may consist of cash, cash equivalents, liquid debt, equity securities or other acceptable assets.

Swaps. A Fund will calculate the net amount, if any, of its obligations relating to swaps on a daily basis and will segregate an amount of cash or other liquid assets having an aggregate value at least equal to this net amount.

Caps, Floors and Collars. Caps, floors and collars require segregation of assets with a value equal to a Fund’s net obligation, if any.

Hedging and other strategic transactions may be covered by means other than those described above when consistent with applicable regulatory policies. A Fund also may enter into offsetting transactions so that its combined position, coupled with any segregated assets, equals its net outstanding obligation. A Fund could purchase a put option, for example, if the exercise price of that option is the same or higher than the exercise price of a put option sold by the Fund. In addition, if it holds a futures contracts or forward contract, a Fund could, instead of segregating assets, purchase a put option on the same futures contract or forward contract with an exercise price as high as or higher than the price of the contract held. Other hedging and strategic transactions also may be offset in combinations. If the offsetting transaction terminates on or after the time the primary transaction terminates, no segregation is required, but if it terminates prior to that time, assets equal to any remaining obligation would need to be segregated.

Risk of Potential Government Regulation of Derivatives

It is possible that additional government regulation of various types of derivative instruments, including futures, options on futures and swap agreements, may limit or prevent a Fund from using such instruments as part of its investment strategy, which could negatively impact the Fund. While many provisions of the Dodd-Frank Act have yet to be implemented through rulemaking, and any regulatory or legislative activity may not necessarily have a direct, immediate effect upon a Fund, it is possible that, upon implementation of these measures or any future measures, they could potentially limit or completely restrict the ability of a Fund to use these instruments as a part of its investment strategy, increase the costs of using these instruments or make them less effective. Likewise, the SEC has proposed

regulations that, if adopted, would significantly change the manner in which a Fund must segregate assets to cover its future obligations. The proposed regulations would restrict a Fund’s ability to enter into derivative transactions for speculative or hedging purposes and would require the Board to adopt a derivative risk management and governance framework. These regulations could also limit the ability of a Fund to use these instruments as part of its investment management strategy, increase the costs of using these instruments, or make them less effective. Limits or restrictions applicable to the counterparties with which a Fund engages in derivative transactions also could prevent the Fund from using these instruments, or affect the pricing or other factors relating to these instruments, or may change the availability of certain investments.

Other Limitations

A Fund will not maintain open short positions in futures contracts, call options written on futures contracts, and call options written on securities indices if, in the aggregate, the current market value of the open positions exceeds the current market value of that portion of its securities portfolio being hedged by those futures and options, plus or minus the unrealized gain or loss on those open positions. The gain or loss on these open positions will be adjusted for the historical volatility relationship between that portion of the Fund and the contracts (e.g., the Beta volatility factor). In the alternative, however, a Fund could maintain sufficient liquid assets in a segregated account equal at all times to the current market value of the open short position in futures contracts, call options written on futures contracts and call options written on securities indices, subject to any other applicable investment restrictions.

For purposes of this limitation, to the extent a Fund has written call options on specific securities in that portion of its portfolio, the value of those securities will be deducted from the current market value of that portion of the securities portfolio. If this limitation should be exceeded at any time, the Fund will take prompt action to close out the appropriate number of open short positions to bring its open futures and options positions within this limitation.

INVESTMENT RESTRICTIONS

There are two classes of investment restrictions to which a Fund is subject in implementing its investment policies: (a) fundamental and (b) non-fundamental. Fundamental restrictions may only be changed by a vote of the lesser of: (i) 67% or more of the shares represented at a meeting at which more than 50% of the outstanding shares are represented; or (ii) more than 50% of the outstanding shares. Non-fundamental restrictions are subject to change by the Board without shareholder approval.

When submitting an investment restriction change to the holders of a Fund’s outstanding voting securities, the matter shall be deemed to have been effectively acted upon if a majority of the outstanding voting securities of the Fund votes for the approval of the matter, notwithstanding: (1) that the matter has not been approved by the holders of a majority of the outstanding voting securities of any other series of the Trust affected by the matter, and (2) that the matter has not been approved by the vote of a majority of the outstanding voting securities of the Trust as a whole.

Fundamental Investment Restrictions

(1) Concentration. A Fund will not concentrate its investments in a particular industry, as that term is used in the 1940 Act, as amended, and as interpreted or modified by regulatory authority having jurisdiction, from time to time.

(2) Borrowing. A Fund will not borrow money, except as permitted under the 1940 Act, as amended, and as interpreted or modified by regulatory authority having jurisdiction, from time to time.

(3) Underwriting. A Fund will not engage in the business of underwriting securities issued by others, except to the extent that the Fund may be deemed to be an underwriter in connection with the disposition of portfolio securities.

(4) Real Estate. A Fund will not purchase or sell real estate, which term does not include securities of companies which deal in real estate or mortgages or investments secured by real estate or interests therein, except that the Fund reserves freedom of action to hold and to sell real estate acquired as a result of the Fund’s ownership of securities.

(5) Commodities. A Fund will not purchase or sell commodities, except as permitted under the 1940 Act, as amended, and as interpreted or modified by regulatory authority having jurisdiction, from time to time.

(6) Loans. A Fund will not make loans except as permitted under the 1940 Act, as amended, and as interpreted or modified by regulatory authority having jurisdiction, from time to time.

(7) Senior Securities. A Fund will not issue senior securities, except as permitted under the 1940 Act, as amended, and as interpreted or modified by regulatory authority having jurisdiction, from time to time.

For purposes of fundamental restriction No. 7, purchasing securities on a when-issued, forward commitment or delayed delivery basis and engaging in hedging and other strategic transactions will not be deemed to constitute the issuance of a senior security.

Non-Fundamental Investment Restrictions

A Fund will not:

(8) Knowingly invest more than 15% of the value of its net assets in securities or other investments, including repurchase agreements maturing in more than seven days but excluding master demand notes, which are not readily marketable.

(9) Make short sales of securities or maintain a short position, if, when added together, more than 25% of the value of the Fund’s net assets would be: (i) deposited as collateral for the obligation to replace securities borrowed to effect short sales; and (ii) allocated to segregated accounts in connection with short sales, except that it may obtain such short-term credits as may be required to clear transactions. For purposes of this restriction, collateral arrangements with respect to hedging and other strategic transactions will not be deemed to involve the use of margin. Short sales “against-the-box” are not subject to this limitation.

(10) Pledge, hypothecate, mortgage or transfer (except as provided in restriction (7)) as security for indebtedness any securities held by the Fund, except in an amount of not more than 10% of the value of the Fund’s total assets and then only to secure borrowings permitted by restrictions (2) and (9). For purposes of this restriction, collateral arrangements with respect to hedging and other strategic transactions will not be deemed to involve a pledge of assets.

For purposes of restriction (10), “other strategic transactions” can include short sales and derivative transactions intended for non-hedging purposes.

Additional Information Regarding Fundamental Restrictions

Concentration. While the 1940 Act does not define what constitutes “concentration” in an industry, the staff of the SEC takes the position that any fund that invests more than 25% of its total assets in a particular industry (excluding the U.S. government, its agencies or instrumentalities) is deemed to be “concentrated” in that industry. With respect to a Fund’s investment in loan participations, if any, the Fund treats both the borrower and the financial intermediary under a loan participation as issuers for purposes of determining whether the Fund has concentrated in a particular industry.

Borrowing. The 1940 Act permits a fund to borrow money in amounts of up to one-third of its total assets, at the time of borrowing, from banks for any purpose (a fund’s total assets include the amounts being borrowed). To limit the risks attendant to borrowing, the 1940 Act requires a fund to maintain at all times an “asset coverage” of at least 300% of the amount of its borrowings, not including borrowings for temporary purposes in an amount not exceeding 5% of the value of its total assets. “Asset coverage” means the ratio that the value of a fund’s total assets (including amounts borrowed), minus liabilities other than borrowings, bears to the aggregate amount of all borrowings.

Commodities. Under the federal securities and commodities laws, certain financial instruments such as futures contracts and options thereon, including currency futures, stock index futures or interest rate futures, and certain swaps, including currency swaps, interest rate swaps, swaps on broad-based securities indices and certain credit default swaps, may, under certain circumstances, also be considered to be commodities. Nevertheless, the 1940 Act does not prohibit investments in physical commodities or contracts related to physical commodities. Funds typically

invest in futures contracts and related options on these and other types of commodity contracts for hedging purposes, to implement tax or cash management strategies, or to enhance returns.

Loans. Although the 1940 Act does not prohibit a fund from making loans, SEC staff interpretations currently prohibit funds from lending more than one-third of their total assets, except through the purchase of debt obligations or the use of repurchase agreements. A repurchase agreement is an agreement to purchase a security, coupled with an agreement to sell that security back to the original seller on an agreed-upon date at a price that reflects current interest rates. The SEC frequently treats repurchase agreements as loans.

Senior Securities. “Senior securities” are defined as fund obligations that have a priority over the fund’s shares with respect to the payment of dividends or the distribution of fund assets. The 1940 Act prohibits a fund from issuing any class of senior securities or selling any senior securities of which it is the issuer, except that the fund is permitted to borrow from a bank so long as, immediately after such borrowings, there is an asset coverage of at least 300% for all borrowings of the fund (not including borrowings for temporary purposes in an amount not exceeding 5% of the value of the fund’s total assets). In the event that such asset coverage falls below this percentage, a fund must reduce the amount of its borrowings within three days (not including Sundays and holidays) so that the asset coverage is restored to at least 300%. The fundamental investment restriction regarding senior securities will be interpreted so as to permit collateral arrangements with respect to swaps, options, forward or futures contracts or other derivatives, or the posting of initial or variation margin.

Except with respect to the fundamental investment restriction on borrowing, if a percentage restriction is adhered to at the time of an investment, a later increase or decrease in the investment’s percentage of the value of the Fund’s total assets resulting from a change in such values or assets will not constitute a violation of the percentage restriction. Any subsequent change in a rating assigned by any rating service to a security (or, if unrated, any change in the subadvisor’s assessment of the security), or change in the percentage of portfolio assets invested in certain securities or other instruments, or change in the average duration of the Fund’s investment portfolio, resulting from market fluctuations or other changes in the Fund’s total assets will not require the Fund to dispose of an investment until the subadvisor determines that it is practicable to sell or close out the investment without undue market or tax consequences to the Fund. In the event that rating services assign different ratings to the same security, the subadvisor will determine which rating it believes best reflects the security’s quality and risk at that time, which may be the higher of the several assigned ratings.

Investment Policies that May Be Changed Only on 60 Days’ Notice to Shareholders

In order to comply with Rule 35d-1 under the 1940 Act, each Fund’s 80% investment policy is subject to change only upon 60 days’ prior notice to shareholders. Refer to the applicable Prospectus for each Fund’s “Principal investment strategies.”

PORTFOLIO TURNOVER

The annual rate of portfolio turnover will normally differ for each Fund and may vary from year to year as well as within a year. A high rate of portfolio turnover (100% or more) generally involves correspondingly greater brokerage commission expenses, which must be borne directly by the Fund. Portfolio turnover is calculated by dividing the lesser of purchases or sales of portfolio securities during the fiscal period by the monthly average of the value of the Fund’s portfolio securities. (Excluded from the computation are all securities, including options, with maturities at the time of acquisition of one year or less). Portfolio turnover rates can change from year to year due to various factors, including, among others, portfolio adjustments made in response to market conditions.
