All the Funds are affected by changes in the economy, or in securities and other markets. There is also the possibility that investment decisions the Adviser makes with respect to the investments of the Funds will not accomplish what they were designed to achieve or that the investments will have disappointing performance.

Risk is the chance that you will lose money on your investment or that it will not earn as much as you expect. In general, the greater the risk, the more money your investment has the potential to earn for you — and the more you can lose. Because the Funds hold securities with fluctuating market prices, the value of each Fund’s shares will vary as its portfolio securities increase or decrease in value. Therefore, the value of your investment in a Fund could go down as well as up.

Your investment in a Fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, entity, or person. You can lose money by investing in a Fund. When you sell your shares of a Fund, they could be worth more or less than what you paid for them.

The following tables summarize the principal risks of investing in each Fund. Your Investment In A Fund May Be Subject (in Varying Degrees) To These Risks As Well As Other Risks. Each Fund May Be More Susceptible To Some Of The Risks Than Others. Risks not marked for a particular Fund may, however, still apply to some extent to that Fund at various times.

Asset-Backed Securities Risk

Asset-backed securities are bonds or notes backed by a discrete pool of financial assets such as credit card receivables, automobile receivables and student loans. The impairment of the value of the financial assets underlying an asset-backed security, such as the non-payment of loans, may result in a reduction in the value of such asset-backed security. Certain asset-backed securities do not have the benefit of the same security interest in the underlying financial assets as do mortgage-backed securities, nor are they provided government guarantees of repayment. Accordingly, issuers of asset-backed securities may have limited ability to enforce the security interest in the underlying assets, and credit enhancements provided to support the asset-backed securities, if any, may be inadequate to protect investors in the event of default. For example, credit card receivables are generally unsecured, and the debtors are entitled to the protection of a number of state and federal consumer credit laws, many of which give such debtors the right to set off certain amounts owed on the credit cards, thereby reducing the balance due. In addition, some issuers of automobile receivables permit the servicers to retain possession of the underlying obligations. If the servicer were to sell these obligations to another party, there is a risk that the purchaser would acquire an interest superior to that of the holders of the related automobile receivables. Asset-backed securities are also

subject to prepayment risk in a declining interest rate environment and extension risk in a rising interest rate environment.

Certain Funds may invest in collateralized debt obligations (“CDOs”), which are debt instruments backed solely by a pool of other debt securities. CDOs include collateralized bond obligations (“CBOs”), collateralized loan obligations (“CLOs”) and other similarly structured securities. CBOs and CLOs are types of asset-backed securities. A CBO is a trust typically collateralized by a diversified pool of high-risk, below investment grade fixed income securities. A CLO is a trust typically collateralized by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans, and subordinate corporate loans, and may include loans that are rated below investment grade or equivalent unrated loans. CDOs may charge management fees and administrative expenses.

The risks of an investment in a CBO, CLO, or other CDO depend largely on the type of the collateral securities (which would have the risks described elsewhere in this Prospectus for that type of security) and the class of the CBO, CLO or other CDO in which a Fund invests. Some CBOs, CLOs and other CDOs have credit ratings, but are typically issued in various classes with various priorities. Normally, CBOs, CLOs and other CDOs are privately offered and sold (that is, not registered under the federal securities laws) and may be characterized by a Fund as illiquid securities, but an active dealer market may exist for CBOs, CLOs and other CDOs that qualify for Rule 144A transactions. In addition to the normal interest rate, default and other risks of fixed income securities discussed elsewhere in this Prospectus, CBOs, CLOs and other CDOs carry additional risks, including the possibility that distributions from collateral securities will not be adequate to make interest or other payments, the collateral may decline in value or default, a Fund may invest in CBOs, CLOs or other CDOs that are subordinate to other classes, volatility in values, and the complex structure of the security may not be fully understood at the time of investment, which may result in disputes with the issuer or produce unexpected investment results.

Counterparty Risk

Counterparty risk refers to the risk that the other party to a contract, such as individually negotiated or over-the-counter derivatives (e.g., swap agreements that are not centrally cleared and participations in loan obligations), will not fulfill its contractual obligations, which may cause losses or additional costs to a Fund or cause a Fund to experience delays in recovering its assets.

Credit Risk

Credit risk refers to the risk that an issuer may default in the payment of principal and/or interest on a security. Financial strength and solvency of an issuer are the primary factors influencing credit risk. In addition, lack of or inadequacy of collateral or credit enhancements for a fixed income security may affect its credit risk. Credit risk of a security may change over time, and securities which are rated by ratings agencies are often reviewed and may be subject to downgrade. However, ratings are only opinions of the agencies issuing them and are not absolute guarantees as to quality.

Debt Securities Risk

Debt securities are subject to various risks. Debt securities are subject to two primary (but not exclusive) types of risk: credit risk and interest rate risk. These risks can affect a debt security’s price volatility to varying degrees, depending upon the nature of the instrument. Other factors, such as market fluctuations and the depth and liquidity of the market for an individual or class of debt security, can also affect the value of a debt security and, hence, the market value of a Fund.

Derivatives Risk

The Funds may invest in derivatives, which are financial instruments whose performance is derived, at least in part, from the performance of an underlying instrument, such as a currency, security, commodity, interest rate or index. The Funds invest in futures, options and swaps, but may use other types of financial derivatives. The various derivative instruments that the Funds may use are described in more detail here and under “Derivative Instruments” in the Statement of Additional Information. The Funds typically use derivatives as a substitute for directly investing in an underlying asset and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate or currency risk. The Funds also may use derivatives for leverage, in which case their use would involve leverage risk.

The Funds’ use of derivative instruments involves risks different from, and possibly greater than, the risks associated with investing directly in securities and other traditional investments. Derivatives are subject to a number of risks described elsewhere in this section, such as liquidity risk, interest rate risk, market risk, credit risk and management risk. They also involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. If a Fund invests in a derivative instrument it could lose more than the principal amount invested.

Also, suitable derivative transactions may not be available in all circumstances and there can be no assurance that a Fund will engage in these transactions to reduce exposure to other risks when that would be beneficial.

The Funds’ participation in the options or futures markets, as well as the use of various swap instruments, involves investment risks and transaction costs to which a Fund would not be subject absent the use of these strategies. If the Adviser’s predictions of movements in the direction of the securities and interest rate markets are inaccurate, the adverse consequences to a Fund may leave the Fund in a worse position than if such strategies were not used. Risks inherent in the use of options, futures contracts and options on futures contracts include: (i) dependence on the Adviser’s ability to predict correctly movements in the direction of interest rates and securities prices; (ii) imperfect correlation between the price of options and futures contracts and options thereon and movements in the prices of the securities being hedged; (iii) the fact that skills needed to use these strategies are different from those needed to select portfolio securities; (iv) the absence of a liquid secondary market for any particular instrument at any time; (v) the possible need to defer closing out certain hedged positions to avoid adverse tax consequences; and (vi) the possible inability of a Fund to purchase or sell a portfolio security at a time that otherwise would be favorable for it to do so, or the possible need for a Fund to sell the security at a disadvantageous time, due to the requirement that the Fund maintain “cover” or collateral securities in connection with futures transactions and certain options. A Fund could lose the entire amount it invests in futures and other derivatives. The loss from investing in certain derivatives is potentially unlimited. There also is no assurance that a liquid secondary market will exist for futures contracts and options in which a Fund may invest. Each Fund limits its investments in futures contracts so that the notional value (meaning the stated contract value) of the futures contracts does not exceed the net assets of that Fund. Derivatives, such as swaps, forward contracts and non-deliverable forward contracts, are subject to regulation under the U.S. Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) and other laws or regulations in Europe and other foreign jurisdictions. Under the Dodd-Frank Act, certain derivatives have become subject to new and increased margin requirements, which in some cases has increased the costs to the Funds of trading derivatives and may reduce returns to shareholders in the Funds.

Distressed and Defaulted Securities Risk

A security held by a Fund may default, or the issuer of a security held by a Fund may become distressed, after the Fund’s investment. The Flexible Income Fund, Floating Rate income Fund, High Yield Bond Fund, Intermediate Bond Fund, Low Duration Bond Fund, Strategic Income Fund, Total Return Bond Fund, and Unconstrained Bond Fund may invest in securities that are distressed or defaulted at the time of investment. Repayment of defaulted securities and obligations of distressed issuers (including insolvent issuers or issuers in payment or covenant default, in workout or restructuring or in bankruptcy or solvency proceedings) is subject to significant uncertainties. A Fund will generally not receive interest payments on distressed or defaulted securities and may incur costs to protect its investment. In addition, distressed or defaulted securities involve the substantial risk that principal will not be repaid. A Fund may incur additional expenses to the extent it is required to seek recovery upon a default in the payment of principal of or interest on its portfolio holdings. In any reorganization or liquidation proceeding relating to a portfolio company, a Fund may lose its entire investment or may be required to accept cash or securities with a value less than its original investment. Distressed or defaulted securities and any securities received in an exchange for such securities may be subject to restrictions on resale. Investments in defaulted securities and obligations of distressed issuers are considered speculative.

Emerging Markets Risk

The risks described under “Principal Risks — Foreign Investing Risk” also apply to emerging market securities, and the risks of investing in emerging market countries tend to be greater as compared to the risks of investing in more developed countries.

Investing in emerging and developing market countries involves substantial risk due to, among other factors, higher brokerage costs in certain countries; different accounting standards; thinner trading markets as compared to those in developed countries; the possibility of currency transfer restrictions; and the risk of expropriation, nationalization or other adverse political, economic or social developments.

Political and economic structures in some emerging and developing market countries may be undergoing significant evolution and rapid development, and such countries may lack the social, political and economic stability characteristics of developed countries. Some of these countries have in the past failed to recognize private property rights and have at

times nationalized or expropriated the assets of private companies. Such social, political and economic instability could disrupt the financial markets in which the Funds invest and adversely affect the value of their investment portfolios.

The securities markets of emerging and developing market countries can be substantially smaller, less developed, less liquid and more volatile than the major securities markets in the U.S. and other developed nations. The limited size of many securities markets in emerging and developing market countries and limited trading volume in issuers compared to the volume in U.S. securities or securities of issuers in other developed countries could cause prices to be erratic for reasons other than factors that affect the quality of the securities. For example, limited market size may cause prices to be unduly influenced by traders who control large positions. Adverse publicity and investors’ perceptions, whether or not based on fundamental analysis, may decrease the value and liquidity of portfolio securities, especially in these markets.

In addition, emerging and developing market countries’ exchanges and broker-dealers are generally subject to less government and exchange regulation than their counterparts in developed countries. Brokerage commissions, dealer concessions, custodial expenses and other transaction costs are generally higher in emerging and developing market countries than in developed countries. As a result, funds that invest in emerging and developing market countries generally have operating expenses that are higher than funds investing in more established market regions.

Currencies of emerging and developing market countries experience devaluations relative to the U.S. dollar from time to time. A devaluation of the currency in which investment portfolio securities are denominated will negatively impact the value of those securities in U.S. dollar terms. Emerging and developing market countries have and may in the future impose foreign currency controls and repatriation controls.

Equity Risk

Equity securities may include common stock, preferred stock or other securities representing an ownership interest or the right to acquire an ownership interest in an issuer. Equity risk is the risk that stocks and other equity securities generally fluctuate in value more than bonds and may decline in value over short or extended periods. The value of stocks and other equity securities may be affected by changes in an issuer’s financial condition, factors that affect a particular industry or industries, such as labor shortages or an increase in production costs and competitive conditions within an industry,

or as a result of changes in overall market, economic and political conditions that are not specifically related to a company or industry, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates or generally adverse investor sentiment.

Preferred Securities are subject to issuer-specific and market risks applicable generally to equity securities. Preferred securities may pay fixed or adjustable rates of return. In addition, a company’s preferred securities generally pay dividends only after the company makes required payments to holders of its bonds and other debt. For this reason, the value of preferred securities will usually react more strongly than bonds and other debt to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred stock of larger companies.

Extension Risk

Extension risk is the risk that in times of rising interest rates, borrowers may pay off their debt obligations more slowly, causing securities considered short- or intermediate-term to become longer-term securities that fluctuate more widely in response to changes in interest rates than shorter-term securities. This may cause the market value of such securities to decline and will also delay the Fund’s ability to reinvest proceeds at higher interest rates. Extension risk applies primarily to mortgage-related and other asset-backed securities.

Foreign Currency Risk

Funds that invest in foreign (non-U.S.) currencies or in foreign securities that are denominated, trade and/or receive revenues in foreign (non-U.S.) currencies are subject to the risk that those foreign currencies may decline in value relative to the U.S. dollar. In the case of currency hedging positions, a Fund is subject to the risk that the U.S. dollar may decline in value relative to the currency being hedged. Currency exchange rates may fluctuate significantly and unpredictably. As a result, a Fund’s investments in foreign currencies, in foreign securities that are denominated, trade, and/or receive revenues in foreign currencies, or in derivatives that provide exposure to foreign currencies may reduce the returns of the Funds.

Foreign Investing Risk

Investments in foreign securities may involve greater risks than investing in U.S. securities.

As compared to U.S. companies, foreign issuers generally disclose less financial and other information publicly and are subject to less stringent and less uniform accounting, auditing and financial reporting standards. Foreign countries typically impose less thorough regulations on brokers, dealers, stock exchanges, corporate insiders and listed companies than does the U.S., and foreign securities markets may be less liquid and more volatile than U.S. markets. Investments in foreign securities generally involve higher costs than investments in U.S. securities, including higher transaction and custody costs as well as additional taxes imposed by foreign governments. In addition, security trading practices abroad may offer less protection to investors such as the Funds. Political or social instability, civil unrest, acts of terrorism and regional economic volatility are other potential risks that could impact an investment in a foreign security. Settlement of transactions in some foreign markets may be delayed or may be less frequent than in the U.S., which could affect the liquidity of a Fund’s portfolio.

The European financial markets have continued to experience volatility because of concerns about economic downturns and about high and rising government debt levels of several countries in the European Union (“EU”) and Europe generally. These events have adversely affected the exchange rate of the Euro and the European securities markets, and may spread to other countries in Europe, including countries that do not use the Euro. These events may affect the value and liquidity of certain of the Funds’ investments. Responses to the financial problems by EU governments, central banks and others, including austerity measures and reforms, may not work, may result in social unrest and may limit future growth and economic recovery or have other unintended consequences. Further defaults or restructurings by governments and others of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world.

In a public referendum in June 2016, the United Kingdom (“UK”) voted to leave the EU (a process now commonly referred to as “Brexit”). In a public referendum in June 2016, the United Kingdom (“UK”) voted to leave the EU (a process now commonly referred to as “Brexit”). On March 29, 2017, the UK delivered its formal notice of withdrawal from the EU to the European Council. On January 31, 2020, the UK officially withdrew from the EU and entered into a transition period until December 31, 2020, during which the UK will effectively remain in the EU from an economic perspective but will no longer have political representation on the EU parliament. During the transition period, the UK and EU will seek

to negotiate and finalize a new trade agreement. It is possible that the transition period could be extended for up to two years. There is considerable uncertainty surrounding the outcome of the negotiations for a new trade agreement, and the impact of Brexit on the UK, the EU and the broader global economy may be significant. As a result of the political divisions within the UK and between the UK and the EU that the referendum vote and the negotiations have highlighted and the uncertain consequences of a Brexit, the UK and European economies and the broader global economy could be significantly impacted, which may result in increased volatility and illiquidity, and potentially lower economic growth on markets in the UK, Europe and globally, which could potentially have an adverse effect on the value of the Fund’s investments. Brexit may also cause additional member states to contemplate departing from the EU, which would likely perpetuate political and economic instability in the region and cause additional market disruption in global financial markets.

Frequent Trading Risk

Frequent trading of portfolio securities may produce capital gains, which are taxable to shareholders when distributed. As a result, frequent trading may cause higher levels of current tax liability to shareholders in a Fund. Frequent trading will lead to increased portfolio turnover and increase the total amount of commissions or mark-ups to broker-dealers that a Fund pays when it buys and sells securities, which may reduce the Fund’s performance.

Futures Contracts Risk

Investing in futures contracts involves various risks, including (1) the imperfect correlation between a futures contract and the change in market value of the underlying instrument held by the Fund; (2) a high degree of leverage because of the low collateral deposits normally involved in futures trading; (3) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (4) losses caused by unanticipated market movements, which are potentially unlimited; and (5) the inability of the Fund to execute a trade because of the maximum permissible price movements exchanges may impose on futures contracts.

Interest Rate Risk

Interest rate risk is the potential for a decline in bond prices due to rising interest rates. In general, bond prices vary inversely with interest rates. The change in a bond’s price depends on several factors, including the bond’s maturity

date. The degree to which a bond’s price will change as a result of changes in interest rates is measured by its “duration.” For example, the price of a bond with a 5-year duration would be expected under normal market conditions to decrease 5% for every 1% increase in interest rates. Generally, bonds with longer maturities have a greater duration and thus are subject to greater price volatility from changes in interest rates. Adjustable rate instruments also react to interest rate changes in a similar manner although generally to a lesser degree (depending, however, on the characteristics of the reset terms, including the index chosen, frequency of reset and reset caps or floors, among other things). It is possible that there will be less governmental action in the future to maintain low interest rates. The negative impact on fixed income securities from interest rate increases, regardless of the cause, could be swift and significant, which could result in significant losses by the Funds, even if anticipated by the Adviser.

Interest rates in the United States and many parts of the world, including certain European countries, are at or near historically low levels. The Federal Reserve Board (the “Federal Reserve”) raised its benchmark interest rate several times in 2018 as the U.S. labor market strengthened and economic activity accelerated and has since lowered its benchmark rate three times in 2019 as signs of economic weakness have appeared. It is possible that the Federal Reserve may change its benchmark rate again in the near future.

Changing interest rates may have unpredictable effects on fixed income and related markets, may result in heightened market volatility and may detract from Fund performance to the extent that the Fund is exposed to interest rates. During periods of low interest rates, a Fund may be unable to maintain positive returns. Increases in interest rates may reduce liquidity for certain Fund investments, which could cause the value of a Fund’s investments and share price to decline. Interest rate increases may also lead to heightened Fund redemption activity, which may cause a Fund to lose value as a result of the costs that it incurs in turning over its portfolio and may lower its performance. A Fund that invests in derivatives tied to fixed income markets may be more substantially exposed to these risks than a Fund that does not invest in those derivatives.

Issuer Risk

The value of securities held by a Fund may decline for a number of reasons directly related to an issuer, such as changes in the financial condition of the issuer, management

performance, financial leverage and reduced demand for the issuer’s goods or services. The amount of dividends paid with respect to equity securities, or the ability of an issuer to make payments in connection with debt securities, may decline for reasons that relate to the issuer, such as changes in an issuer’s financial condition or a decision by the issuer to pay a lower dividend, or for reasons that relate to the broader financial system. In addition, there may be limited public information available for the Adviser to evaluate foreign issuers.

Junk Bond Risk

Debt securities that are rated below investment grade are commonly known as high yield securities or “junk bonds.” Junk bonds (including low-rated and comparable unrated securities), while generally offering higher yields than investment grade securities with similar maturities, involve greater risks, including the possibility of default or bankruptcy. Junk bonds are regarded as speculative with respect to an issuer’s capacity to pay interest and to repay principal. They are usually issued by companies without long track records of sales and earnings, or by companies with questionable credit strength. They may also be issued by highly leveraged companies, which may be less able to meet their contractual obligations than a less leveraged company. These bonds have a higher degree of default risk and may be less liquid than higher-rated bonds. These securities may be subject to greater price volatility due to such factors as specific issuer developments, interest rate sensitivity, and negative perceptions of junk bonds generally. In addition, junk bonds tend to be less marketable than higher-quality debt securities because the market for them is not as broad or active. The potential lack of a liquid secondary market may have an adverse effect on the market price of, and a Fund’s ability to sell, particular securities, and may make it more difficult for the Adviser to accurately value certain high yield securities held by a Fund.

Leverage Risk

Leverage created from certain types of transactions or instruments, such as borrowing, engaging in reverse repurchase agreements, entering into futures contracts or forward currency contracts, engaging in forward commitment transactions and investing in leveraged or unleveraged commodity index-linked notes, may impair a Fund’s liquidity, cause it to liquidate positions at an unfavorable time, increase its volatility or otherwise cause it not to achieve its intended result. During periods of adverse market conditions, the use of leverage may cause a Fund to lose more money than would have been the case if leverage was not used. To the extent

required by applicable law or regulation, the Funds will reduce leverage risk by either segregating an equal amount of liquid assets or “covering” the transactions that introduce such risk.

Liquidity Risk

A Fund’s investments in illiquid securities may reduce the returns of the Fund because it may not be able to sell the illiquid securities at an advantageous time or price. Investments in high yield securities, foreign securities, derivatives or other securities with substantial market and/or credit risk tend to have the greatest exposure to liquidity risk. Certain investments in private placements and Rule 144A Securities may be considered illiquid investments.

Furthermore, reduced number and capacity of dealers and other counterparties to “make markets” in fixed income securities, in connection with the growth of the fixed income markets, may increase liquidity risk with respect to a Fund’s investments in fixed income securities. When there is no willing buyer and investments cannot be readily sold, a Fund may have to sell them at a lower price or may not be able to sell the securities at all, each of which would have a negative effect on the Fund’s performance. These securities may also be difficult to value and their values may be more volatile because of liquidity risk. Increased Fund redemption activity, which may occur in a rising interest rate environment or for other reasons, may negatively impact Fund performance and increase liquidity risk due to the need of the Fund to sell portfolio securities. Regulations such as the Volcker Rule or future regulations may further constrain the ability of market participants to create liquidity, particularly in times of increased market volatility. The liquidity of a Fund’s assets may change over time.

Below investment grade mortgage-backed securities are subject to additional liquidity risks, which are discussed above under “Principal Risks – Below Investment Grade Mortgage-Backed Securities.”

Market Risk

Various market risks can affect the price or liquidity of an issuer’s securities in which a Fund may invest. Returns from the securities in which a Fund invests may underperform returns from the various general securities markets or different asset classes. Different types of securities tend to go through cycles of outperformance and underperformance in comparison to the general securities markets. Adverse events occurring with respect to an issuer’s performance or financial position can depress the value of the issuer’s securities. The

liquidity in a market for a particular security will affect its value and may be affected by factors relating to the issuer, as well as the depth of the market for that security. Other market risks that can affect value include a market’s current attitudes about types of securities, market reactions to political or economic events, including litigation, and tax and regulatory effects (including lack of adequate regulations for a market or particular type of instrument).

Instability in the financial markets has led the U.S. government to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility, and in some cases a lack of liquidity. Federal, state, and other governments, their regulatory agencies, or self-regulatory organizations may take actions that affect the regulation of the securities in which a Fund invests or the issuers of such securities in ways that are unforeseeable. Legislation or regulation may also change the way in which the Funds are regulated. Such legislation or regulation could limit or preclude a Fund’s ability to achieve its investment objective.

Mortgage-Backed Securities Risk

Mortgage-backed securities represent participation interests in pools of mortgage loans purchased from individual lenders by a federal agency or originated and issued by private lenders. Mortgage-backed securities are subject to prepayment risk, which is the risk that in times of declining interest rates, an issuer of mortgage-backed securities or other debt securities may be able to repay principal prior to the security’s maturity, causing a Fund to have to reinvest in securities with a lower yield or higher risk of default and reducing a Fund’s income or return potential. Mortgage-backed securities are also subject to extension risk, which is the risk that in times of rising interest rates, borrowers may pay off their debt obligations more slowly, causing the market value of such securities to decline and delaying a Fund’s ability to reinvest proceeds at higher interest rates.

Because of prepayment risk and extension risk, mortgage-backed securities react differently to changes in interest rates than other bonds, and the values of some mortgage-backed securities may expose a Fund to a lower rate of return upon reinvestment of principal. When interest rates rise, the value of mortgage-related securities generally will decline; however, when interest rates are declining, the value of mortgage-related securities with prepayment features may not increase as much as other fixed income securities. The rate of prepayments on underlying mortgages will affect the price and volatility of a mortgage-related security, and may shorten

or extend the effective maturity of the security beyond what was anticipated at the time of purchase. If unanticipated rates of prepayment on underlying mortgages increase the effective maturity of a mortgage-related security, the volatility of the security can be expected to increase. The value of these securities may fluctuate in response to the market’s perception of the creditworthiness of the issuers.

Additionally, although mortgages and mortgage-related securities are generally supported by some form of government or private guarantee and/or insurance, there is no assurance that private guarantors or insurers will meet their obligations. Certain mortgage-backed securities are issued or guaranteed by U.S. government agencies or U.S. government-sponsored entities. While mortgage-backed securities issued by Government National Mortgage Association (Ginnie Mae) are backed by the full faith and credit of the U.S. government, mortgage-backed securities issued by various U.S. government-sponsored entities, such as Federal Home Loan Mortgage Corporation (Freddie Mac) and the Federal National Mortgage Corporation (Fannie Mae), are not backed by the full faith and credit of the U.S. government. Although the U.S. government has provided financial support to Fannie Mae and Freddie Mac, there is no assurance that the U.S. government will do so in the future.

Non-U.S. Money Market Securities Risk

Money market securities are generally subject to credit risk, which is the risk that an issuer will default in the payment of principal and/or interest on a security, and the risk that a security’s value may decline for reasons directly related to the issuer, such as management performance, financial leverage and condition of the business. Foreign money-market securities are additionally subject to currency risk, in that foreign currencies may decline in value relative to the U.S. dollar and affect a Fund’s investments in such securities, and they may have less liquidity than similar U.S. securities.

Portfolio Management Risk

Portfolio management risk is the risk that an investment strategy may fail to produce the intended results. There can be no assurance that a Fund will achieve its investment objective. The Adviser’s judgments about the attractiveness, value and potential appreciation of particular securities may prove to be incorrect, and the Adviser may not anticipate actual market movements or the impact of economic conditions generally. No matter how well a portfolio manager evaluates market conditions, the securities a portfolio manager chooses may fail to produce the intended result, and you could lose money on your investment in a Fund.

Prepayment Risk

Prepayment risk arises when interest rates fall because certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields. In periods of falling interest rates, the rate of prepayments tends to increase as borrowers are more likely to pay off debt and refinance at new lower rates. During these periods, reinvestment of the prepayment proceeds will generally be at lower rates of return than the return on the assets that were prepaid. Prepayment reduces the yield to maturity and the average life of the security.

Price Volatility Risk

The value of a Fund’s investment portfolio will change as the prices of its investments go up or down. Different parts of the market and different types of securities can react differently to developments. Issuer, political or economic developments can affect a single issuer, issuers within an industry or economic sector or geographic region or market as a whole.

Prices of most securities tend to be more volatile in the short-term. Therefore, if you trade frequently or redeem in the short-term, you are more likely to incur a loss than an investor who holds investments for the longer-term. The fewer the number of issuers in which a Fund invests, the greater the potential volatility of its portfolio.

Securities Selection Risk

The specific securities held in a Fund’s investment portfolio may underperform those held by other funds investing in the same asset class or those included in benchmarks that are representative of the same asset class because of a portfolio manager’s choice of securities.

Short Sales Risks

The Adviser may cause a Fund to sell a debt or equity security short (that is, without owning it) and to borrow the same security from a broker or other institution to complete the sale. The Adviser may use short sales when it believes a security is overvalued or as a partial hedge against a position in a related security of the same issuer held by a Fund. If the value of the security sold short increases, a Fund would lose money because it will need to replace the borrowed security by purchasing it at a higher price. The potential loss is unlimited. (If the short sale was intended as a hedge against another investment, the loss on the short sale may be fully or partially offset by gains in that other investment.)

A lender may request that the borrowed securities be returned on short notice; if that occurs at a time when other short sellers of the subject security are receiving similar requests, a “short squeeze” can occur. This means that a Fund might be compelled, at the most disadvantageous time, to replace borrowed securities previously sold short, with purchases on the open market at prices significantly greater than those at which the securities were sold short. Short selling also may produce higher than normal portfolio turnover and result in increased transaction costs to the Fund.

Each Fund also may make short sales “against-the-box,” in which the Fund sells short securities it owns. A Fund will incur transaction costs, including interest expenses, in connection with opening, maintaining and closing short sales against-the-box, which result in a “constructive sale,” requiring the Fund to recognize any taxable gain from the transaction.

Sovereign Debt Risk

The Funds may invest in sovereign debt. Investment in sovereign debt can involve a high degree of risk. Legal protections available with respect to corporate issuers (e.g., bankruptcy, liquidation and reorganization laws) do not generally apply to governmental entities or sovereign debt. Accordingly, creditor seniority rights, claims to collateral and similar rights may provide limited protection and may be unenforceable. The governmental entity that controls the repayment of sovereign debt may not be able or willing to repay the principal and/or interest when due in accordance with the terms of such debt. A government entity’s willingness or ability to repay principal and interest due in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its foreign reserves, the availability of sufficient foreign exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the governmental entity’s policy toward the International Monetary Fund, and the political constraints to which a governmental entity may be subject. A Fund may have limited recourse to compel payment in the event of a default.

Swap Agreements Risk

Swap agreements are two-party contracts entered into primarily by institutional investors for periods ranging from a few weeks to more than a year. Swap transactions attempt to obtain a particular return when it is considered desirable to do so, possibly at a lower cost to a Fund than if the Fund had invested directly in an instrument that yielded that desired return. In a standard swap transaction, two parties agree to

exchange the returns earned on specific assets, such as 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 representing a particular index. Whether a Fund’s use of swap agreements will be successful in furthering its investment objectives will depend on the Adviser’s ability to predict correctly whether certain types of investments are likely to produce greater returns than other investments.

Credit default swaps involve parties effectively buying or selling protection with respect to whether an event of default by a selected entity (or entities) will occur. Interest rate swaps involve the exchange of interest payments by a Fund with another party, such as an exchange of floating rate payments for fixed interest rate payments. A total return swap is the generic name for any swap where one party agrees to pay the other the “total return” of a defined underlying asset, usually in return for receiving a stream of cash flows. Total return swaps are most commonly used with indices, single stocks, bonds and defined portfolios of loans and mortgages.

Risks inherent in the use of swaps of any kind include: (1) swap contracts may not be assigned without the consent of the counterparty; (2) potential default of the counterparty to the swap if it is not subject to centralized clearing; (3) absence of a liquid secondary market for any particular swap at any time; and (4) possible inability of a Fund to close out the swap transaction at a time that otherwise would be favorable for it to do so.

Certain types of over-the-counter (“OTC”) derivatives, such as various types of swaps, are required to be cleared through a central clearing organization that is substituted as the counterparty to each side of the transaction. Each party will be required to maintain its positions through a clearing broker. Although central clearing generally is expected to reduce counterparty risk, it creates additional risks. A clearing broker or organization may not be able to perform its obligations. Cleared derivatives transactions may be more expensive to maintain than OTC transactions, or require a Fund to deposit increased margin. A transaction may be subject to unanticipated close-out by the clearing organization or a clearing broker. A Fund may be required to indemnify a swap execution facility or a broker that executes cleared swaps against losses or costs that may be incurred as a result of the Fund’s transactions. A Fund also is subject to the risk that no clearing member is willing to clear a transaction entered into by the Fund.

The U.S. and foreign governments have adopted and implemented, or are in the process of adopting and implementing, regulations governing derivatives markets, including clearing, margin, reporting, and registration requirements. The ultimate impact of the regulations remains unclear. The effect of the regulations could be, among other things, to restrict a Fund’s ability to engage in swap transactions or increase the costs of those transactions.

Unrated Securities Risks

A Fund may purchase unrated securities (which are not rated by a rating agency) if the Adviser determines that the security is of comparable quality to a rated security that the Fund may purchase. Unrated securities may be less liquid than comparable rated securities and involve the risk that the Adviser may not accurately evaluate the security’s comparative credit rating. Analysis of creditworthiness of issuers of high yield securities may be more complex than for issuers of higher-quality fixed income securities. To the extent that a Fund invests in high yield and/or unrated securities, the Fund’s success in achieving its investment objective may depend more heavily on the Adviser’s creditworthiness analysis than if the Fund invested exclusively in higher-quality and rated securities.

U.S. Government Securities Risk

Some U.S. government securities, such as Treasury bills, notes, and bonds and mortgage-backed securities guaranteed by Ginnie Mae, are supported by the full faith and credit of the United States, while others are supported by the right of the issuer to borrow from the U.S. Treasury, by the discretionary authority of the U.S. government to purchase the agency’s obligations, or by the credit of the issuing agency, instrumentality, or enterprise only.

In addition, certain governmental entities have been subject to regulatory scrutiny regarding their accounting policies and practices and other concerns that may result in legislation, changes in regulatory oversight and/or other consequences that could adversely affect the credit quality, availability or investment character of securities issued or guaranteed by these entities.

In recent periods, the values of U.S. government securities have been affected substantially by increased demand for them around the world. Changes in the demand for U.S.

government securities may occur at any time and may result in increased volatility in the values of those securities.

U.S. Treasury Obligations Risk

While credit risk for U.S. Treasury obligations is generally considered low, U.S. Treasury obligations are subject to interest rate risk, particularly for those with longer terms. In addition, certain political events in the U.S., such as a prolonged government shut down, may cause investors to lose confidence in the U.S. government and may cause the value of U.S. Treasury obligations to decline. A significant portion of U.S. Treasury obligations is held by foreign governments, including China, Japan, Ireland and Brazil. Strained relations with these foreign countries may result in the sale of U.S. Treasury obligations by these foreign governments, causing the value of U.S. Treasury obligations to decline.

Valuation Risk

Portfolio instruments may be sold at prices different from the values established by the Fund, particularly for investments that trade in low volume, in volatile markets or over the counter or that are fair valued. Portfolio securities may be valued using techniques other than market quotations in circumstances described under “Net Asset Value and Fair Value Pricing.” This is more likely for certain types of derivatives such as swaps. The value established for a portfolio security may be different than the value that would be produced through the use of another methodology or if it had been priced using market quotations. Portfolio securities that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. A Fund may from time to time purchase an “odd lot” or smaller quantity of a security that trades at a discount to the price of a “round lot” or larger quantity preferred for trading by institutional investors. If a Fund is able to combine an odd lot purchase with an existing holding to make a round lot or larger position in the security, the Fund may be able to immediately increase the value of the security purchased, in accordance with its valuation procedures. There is no assurance that the Fund could sell a portfolio security for the value established for it at any time and it is possible that the Fund would incur a loss because a portfolio security is sold at a discount to its established value.

Borrowing and Use of Leverage Risks

Each Fund may borrow money from banks and engage in reverse repurchase transactions for temporary or emergency purposes. A Fund may borrow from broker-dealers and other institutions to leverage a transaction, provided that the borrowing is fully collateralized. Total bank borrowings may not exceed 10% of the value of a Fund’s assets, except in the case of the Corporate Bond Fund, Flexible Income Fund, Floating Rate Income Fund, High Yield Bond Fund, Investment Grade Credit Fund, Strategic Income Fund, and Unconstrained Bond Fund, for which total bank borrowings may not exceed one-third of the value of the Fund’s assets. A Fund also may leverage its portfolio through margin borrowing and other techniques in an effort to increase total return. Although leverage creates an opportunity for increased income and gain, it also creates certain risks. For example, leveraging may magnify changes in the net asset values of a Fund’s shares and in its portfolio yield. Although margin borrowing will be fully collateralized, a Fund’s assets may change in value while the borrowing is outstanding. Leveraging creates interest expenses that can exceed the income from the assets retained.

Cybersecurity Risk

Information and technology systems relied upon by the Funds, the Adviser, the Funds’ service providers (including, but not limited to, Fund accountants, custodians, transfer agents, administrators, distributors and other financial intermediaries) and/or the issuers of securities in which a Fund invests may be vulnerable to damage or interruption from computer viruses, network failures, computer and telecommunication failures, infiltration by unauthorized persons, security breaches, usage errors, power outages and catastrophic events such as fires, tornadoes, floods, hurricanes and earthquakes. Although the Adviser has implemented measures to manage risks relating to these types of events, if these systems are compromised, become inoperable for extended periods of time or cease to function properly, significant investment may be required to fix or replace them. The failure of these systems and/or of disaster recovery plans could cause significant interruptions in the operations of the Funds, the Adviser, the Funds’ service providers and/or issuers of securities in which a Fund invests and may result in a failure to maintain the security, confidentiality or privacy of sensitive data, including personal information relating to investors (and the beneficial owners of investors). Such a

failure could also harm the reputation of the Funds, the Adviser, the Funds’ service providers and/or issuers of securities in which a Fund invests, subject such entities and their respective affiliates to legal claims or otherwise affect their business and financial performance. There is also a risk that cybersecurity breaches may not be detected, and the Funds and their shareholders could be negatively impacted as a result.

Event Risk

Event risk is the risk that corporate issuers may undergo restructurings, such as mergers, leveraged buyouts, takeovers, or similar events financed by increased debt. As a result of the added debt, the credit quality and market value of a company’s bonds and/or other debt securities may decline significantly.

Financial Services Sector Risk

Companies in the financial services sector may be affected by the overall economic conditions as well as by factors particular to the financial services sector. Financial services companies are subject to extensive government regulations, which may change frequently and may adversely affect the scope of their activities, place restrictions on the amounts and types of loans and other financial commitments they can make, limit the interest rates and fees they can charge, and prescribe the amount of capital they must maintain. In addition, the profitability of businesses in the financial services sector depends heavily on the availability and cost of capital and may fluctuate significantly in response to changes in interest rates and may be negatively impacted by credit rating downgrades and decreased liquidity in the credit market. Businesses in the financial services sector often operate with substantial financial leverage.

Frequent Purchases and Redemptions of Fund Shares Risks

Frequent purchases and redemptions of a Fund’s shares may present certain risks for the Fund and its shareholders. These risks may include, among other things, dilution in the value of Fund shares held by long-term shareholders, interference with the efficient management of the Fund’s portfolios and increased brokerage and administrative costs. A Fund may have difficulty implementing long-term investment strategies if it is unable to anticipate what portion of its assets it should

retain in cash to provide liquidity to its shareholders. Also, excessive purchases and sales or exchanges of a Fund’s shares may force a Fund to maintain a disadvantageously large cash position to accommodate short duration trading activity. Further, excessive purchases and sales or exchanges of a Fund’s shares may force the Fund to sell portfolio securities at inopportune times to raise cash to accommodate frequent trading activity, and could result in increased brokerage, tax, administrative costs or other expenses. It is anticipated that the Ultra Short Bond Fund and the Low Duration Bond Fund are less likely to be adversely affected under normal circumstances, and the other Funds are more likely to be significantly affected, by frequent purchases and sales.

Certain of the Funds may invest in non-U.S. securities; accordingly, there is an additional risk of undetected frequent trading in a Fund’s shares by investors who attempt to take unfair advantage of the Fund’s need to value its portfolio holdings that are traded in markets with closing times different than when the Fund calculates its net asset value, also known as time zone arbitrage. In addition, because certain of the Funds significantly invest in high yield bonds, and because these securities are often infrequently traded, investors may seek to trade Fund shares in an effort to benefit from their understanding of the value of these securities (referred to as price arbitrage).

Investors seeking to engage in disruptive trading practices may deploy a variety of strategies to avoid detection and, despite the efforts of the Funds to prevent disruptive trading, there is no guarantee that the Funds or their agents will be able to identify such investors or curtail their trading practices. The ability of the Funds and their agents to detect and curtail excessive trading or short duration trading practices may also be limited by operational systems and technological limitations. In addition, the Funds receive purchase, exchange and redemption orders through financial intermediaries. These financial intermediaries include, but are not limited to, entities such as broker-dealers, insurance company separate accounts, and retirement plan administrators. The Funds cannot always know or reasonably detect excessive trading which may be facilitated by these intermediaries or by the use of omnibus account arrangements. Omnibus accounts are common forms of holding Fund shares. Entities utilizing such omnibus account arrangements may not identify customers’ trading activity in shares of a Fund on an individual basis. Consequently, although the Fund has procedures and agreements in place intended to detect excessive trading, it may

not always be able to detect frequent or excessive trading in Fund shares attributable to a particular investor who effects purchase and/or exchange activity in Fund shares through a broker, dealer or other financial intermediary acting in an omnibus capacity. Also, there may exist multiple tiers of these entities, each utilizing an omnibus account arrangement that may further compound the difficulty to the Funds of detecting excessive or short duration trading activity in Fund shares. In seeking to prevent disruptive trading practices in the Funds, the Funds consider the information actually available to them at the time. While each of these financial intermediaries may have individual policies concerning frequent or excessive trading, each intermediary has different policies. The Funds are not able to fully assess the effectiveness of its financial intermediaries’ policies concerning frequent or excessive trading. If investing through intermediaries, investors should inquire at that intermediary what frequent purchase and redemption policies will be applied to their investments.

Inside Information Risks

A Fund’s portfolio managers may seek to avoid exposure to material non-public information about the issuers of floating rate loans being considered for purchased by the Fund. Although that inside information could enhance the portfolio managers’ ability to evaluate a potential investment, it would also impair the Fund’s ability to trade that issuer’s securities in compliance with federal securities laws.

LIBOR Risk

LIBOR is used extensively in the U.S. and globally as a “benchmark” or “reference rate” for various commercial and financial contracts, including corporate and municipal bonds, bank loans, asset-backed and mortgage-related securities, interest rate swaps and other derivatives. For example, debt securities in which a Fund invests may pay interest at floating rates based on LIBOR or may be subject to interest caps or floors based on LIBOR. A Fund’s derivative investments may also reference LIBOR. In addition, issuers of instruments in which a Fund invests may obtain financing at floating rates based on LIBOR, and a Fund may use leverage or borrowings based on LIBOR. In July 2017, the head of the United Kingdom Financial Conduct Authority announced the intention to phase out the use of LIBOR by the end of 2021. There is currently no definitive information regarding the future utilization of LIBOR or of any particular replacement reference rate. Abandonment of or modifications to LIBOR could have adverse impacts on newly issued financial instruments and existing financial instruments that reference LIBOR.

The expected discontinuation of LIBOR could have a significant impact on the financial markets and may present a material risk for certain market participants, including investment companies such as the Funds. Abandonment of or modifications to LIBOR could lead to significant short- and long-term uncertainty and market instability. The risks associated with this discontinuation and transition may be

exacerbated if the work necessary to effect an orderly transition to an alternative reference rate is not completed in a timely manner. It remains uncertain how such changes would be implemented and the effects such changes would have on the Funds, issuers of instruments in which the Funds invest, and the financial markets generally.
