The fund's shares will change in value, and you could lose money by investing in the fund. One of the principal risks of investing in the fund is market risk. Market risk is the risk that a particular security owned by the fund, fund shares or securities in general may fall in value. There can be no assurance that the fund's investment objective will be achieved.

An investment in a fund containing securities of non-U.S. issuers is subject to additional risks, including currency fluctuations, political risks, withholding, the lack of adequate financial information, and exchange control restrictions impacting non-U.S. issuers. These risks may be heightened for securities of companies located in, or with significant operations in, emerging market countries.

The fund's NAV is determined on the basis of U.S. dollars, if the fund invests in non-U.S. securities, you may lose money if the local currency of a non-U.S. market depreciates against the U.S. dollar.

The fund may be composed of a very small number of ETFs, which involves additional risk, including limited diversification.

Preferred securities combine some of the characteristics of both common stocks and bonds. Preferred securities are typically subordinated to bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater credit risk than those debt instruments.

Certain securities held by the fund are subject to credit risk, call risk, income risk, inflation risk, interest rate risk, prepayment risk and extension risk. Credit risk is the risk that an issuer of a security will be unable or unwilling to make dividend, interest and/or principal payments when due and that the value of a security may decline as a result. Credit risk is heightened for floating-rate loans and high-yield securities, because companies that issue loans tend to be highly leveraged and thus are more susceptible to the risks of interest deferral, default and/or bankruptcy. Call risk is the risk that if an issuer calls higher-yielding debt instruments held by the fund, performance could be adversely impacted. Income risk is the risk that income from the fund's fixed-income investments could decline during periods of falling interest rates. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. Interest rate risk is the risk that the value of the fixed-income securities in the fund will decline because of rising market interest rates. Prepayment risk is the risk that during periods of falling interest rates, an issuer may exercise its right to pay principal on an obligation earlier than expected. This may result in a decline in a fund's income. Extension risk is the risk that the average life of a security may extend if the rate of prepayments decreases, which increases interest rate exposure.

Convertible securities have characteristics of both equity and debt securities and, as a result, are exposed to certain additional risks.

Mortgage-related securities, including mortgage-backed securities, are more susceptible to adverse economic, political or regulatory events that affect the value of real estate. Mortgage- related securities are subject to the risk that the rate of mortgage prepayments decreases, which extends the average life of a security and increases the interest rate exposure.

Income from municipal bonds held by the fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of a bond issuer.

Investments in sovereign bonds involve special risks because the governmental authority that controls the repayment of the debt may be unwilling or unable to repay the principal and/or interest when due.

Senior floating rate loans are usually rated below investment grade but may also be unrated. As a result, the risks associated with these loans are similar to the risks of high yield fixed income instruments. High yield securities, or "junk" bonds, are subject to greater market fluctuations and risk of loss than securities with higher ratings, and therefore, may be highly speculative. The market for high yield securities is smaller and less liquid than that for investment grade securities.

Illiquid securities involve the risk that the securities will not be able to be sold at the time desired by a fund or at prices approximately the value at which a fund is carrying the securities on its books.

Covenant-lite loans contain fewer maintenance covenants, or no maintenance covenants at all, then traditional loans and may not include terms that allow the lender to monitor the financial performance of the borrower and declare a default if certain criteria are breached.

Securities issued or guaranteed by federal agencies and U.S. government sponsored instrumentalities may or may not be backed by the full faith and credit of the U.S. government.

The fund currently has fewer assets than larger, more established funds, and like other relatively new funds, large inflows and outflows may impact the fund's market exposure for limited periods of time.

The fund may invest in the shares of other investment companies, which involves additional expenses that would not be present in a direct investment in the underlying funds. In addition, the fund's investment performance and risks may be related to the investment performance and risks of the underlying funds.

The fund is classified as "non-diversified" and may invest a relatively high percentage of their assets in a limited number of issuers. As a result, the fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly concentrated in certain issuers.

Actively managed funds are subject to management risk because the advisor or sub-advisor will apply investment techniques and risk analyses that may not have the desired result.
