All investments carry a certain amount of risk, and the Fund cannot guarantee that it will achieve its investment objective. An investment in the Fund is not a deposit or obligation of any bank, is not endorsed or guaranteed by any bank and is not insured by the Federal Deposit Insurance Corporation (“FDIC”) or any other government agency. You may lose money by investing in the Fund.

Listed below are the principal risks of investing in the Fund. The first five risks are presented in an order that reflects the Adviser’s current assessment of relative importance, but this assessment could change over time as the Fund’s portfolio changes or in light of changes in the market or the economic environment, among other things. The remaining risks are presented in alphabetical order to facilitate your ability to find particular risks and compare them with the risk of other funds. The Fund is not required to and will not update this Prospectus solely because its assessment of the relative importance of the principal risks of investing in the Fund changes. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Please see “Additional Principal Risk Information” in this Prospectus for a more detailed description of the Fund’s risks.

Fixed Income Market Risk: Fixed income securities markets may, in response to governmental intervention, economic or market developments (including potentially a reduction in the number of broker-dealers willing to engage in market-making activity), or other factors, experience periods of increased volatility and reduced liquidity.

Mortgage-Backed and Asset-Backed Securities Risk: Mortgage-backed and other asset-backed securities may be particularly sensitive to changes in prevailing interest rates. Rising interest rates tend to extend the duration of mortgage-backed securities, making them more sensitive to changes in interest rates, and may reduce the market value of the securities. Mortgage-backed securities are also subject to pre-payment risk. Due to their often-complicated structures, various mortgage-backed and asset-backed securities may be difficult to value and may constitute illiquid securities. Furthermore, debtors may be entitled to the protection of a number of state and federal consumer protection credit laws with respect to these securities, which may give the debtor the right to avoid or reduce payment.

Active Trading Risk: The Fund may trade securities actively, which could increase its transaction costs (thereby lowering its performance) and may increase the amount of taxes that a shareholder pays, by increasing the amount of the Fund’s realized capital gains and increasing the portion of the Fund’s realized capital gains that are short-term capital gains.

Collateralized Loan Obligations Risk: Collateralized loan obligations are investment vehicles typically collateralized by a pool of loans, which may include, among others, senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. Collateralized loan obligations are subject to the risks of substantial losses due to actual defaults by borrowers of the loans underlying the collateralized loan obligations, which will be greater during periods of economic or financial stress. Collateralized loan obligations may also lose value due to collateral defaults and disappearance of subordinate tranches, market anticipation of defaults, and investor aversion to collateralized loan obligation securities as a class. The Fund may invest in collateralized loan obligations that hold loans of uncreditworthy borrowers, which may absorb losses from underlying borrower defaults before senior tranches. Investments in such collateralized loan obligations present a greater risk of loss. In addition, collateralized loan obligations are subject to interest rate risk and credit risk.

Derivatives Risk: The possibility that the Fund will suffer a loss from its use of derivatives. The primary risk with many derivatives is that they can amplify a gain or loss, potentially earning or losing substantially more money than the actual cost of the derivative instrument. It is possible that the Fund’s liquid assets may be insufficient to support its obligations under its derivatives positions. The Fund’s use of derivatives such as futures transactions and swap transactions involves other risks, such as the credit risk relating to the other party to a derivative contract (which is heightened for over-the-counter swaps and other derivatives as compared to centrally cleared derivatives), the risk of difficulties in pricing and valuation, and the risk that changes in the value of a derivative may not correlate perfectly with relevant assets, rates or indices. There is also the risk that the Fund may be unable to terminate or sell a derivatives position at an advantageous time or price.

Estimated Maturity Risk: The possibility that an underlying security holder will exercise its right to pay principal on an obligation earlier or later than expected. This may happen when there is a rise or fall in interest rates. These events may shorten or lengthen the duration (i.e., interest rate sensitivity) and potentially reduce the value of these securities

Foreign Currency Transaction Risk: Funds that invest directly in foreign currencies and in securities that trade in, or receive revenues in, foreign currencies are subject to the risk that those currencies will fluctuate in value relative to the U.S. dollar.

Income Risk: The possibility that the Fund’s income will decline due to a decrease in interest rates. Income risk is generally higher for shorter-term bonds and lower for longer-term bonds.

Management Risk: The risk that an investment technique used by the Fund’s portfolio manager may fail to produce the intended result. The portfolio managers’ judgments about the markets, the economy or companies may not anticipate actual market movements, economic conditions or company performance, and these judgments may negatively affect the return on your investment.

Municipal Securities Risk: Municipal obligations are issued by or on behalf of states, territories and possessions of the United States and their political subdivisions, agencies and instrumentalities and the District of Columbia to obtain funds for various public purposes. Municipal obligations are subject to more credit risk than U.S. government securities that are supported by the full faith and credit of the United States. The ability of municipalities to meet their obligations will depend on the availability of tax and other revenues, economic, political and other conditions within the state and municipality, and the underlying fiscal condition of the state and municipality. As with other fixed income securities, municipal securities also expose their holders to market risk because their values typically change as interest rates fluctuate.

Operational and Technology Risk: Cyber-attacks, disruptions, or failures that affect the Fund’s service providers, counterparties, market participants, or issuers of securities held by the Fund may adversely affect the Fund and its shareholders, including by causing losses for the Fund or impairing Fund operations.

Prepayment/Call Risk: When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss. Call risk is the possibility that, during periods of declining interest rates, a bond issuer will “call” — or repay — higher-yielding bonds before their stated maturity date. In both cases, investors receive their principal back and are typically forced to reinvest it in bonds that pay lower interest rates.

Secondary Market Liquidity Risk: Shares of the Fund may trade at prices other than NAV. As with all exchange traded funds (“ETFs”), Fund shares may be bought and sold in the secondary market at market prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and there may be times when the market price of the shares is more than the NAV (premium) or less than the NAV (discount). This risk is heightened in times of market volatility or periods of steep market declines. Additionally, in stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s underlying portfolio holdings. When an ETF is first launched, it is unlikely to have immediate secondary market liquidity. There is likely to be a lead market maker making markets of significant size, but it is unlikely there will be many market participants on day one of trading. This lack of secondary market liquidity may make it difficult for investors to transact in Fund shares in the market, and the market price consequently may deviate from the Fund’s NAV. As the Fund begins to trade and as client interest increases, an increasing number of market participants buy or sell shares of the Fund and secondary market liquidity will grow. While all ETFs can be held for prolonged periods or intraday, some ETFs experience more secondary market trading than others.

U.S. Government Securities Risk: The Fund invests in securities issued or guaranteed by the U.S. government or its agencies or instrumentalities (such as Fannie Mae or Freddie Mac securities). Although U.S. government securities issued directly by the U.S. government are guaranteed by the U.S. Treasury, other U.S. government securities issued by an agency or instrumentality of the U.S. government may not be. No assurance can be given that the U.S. government would provide financial support to its agencies and instrumentalities if not required to do so by law.
