The fund is subject to risks, any of which could cause an investor to lose money. The fund’s principal risks include:

Not a Money Fund — The fund is not a money market fund and is not subject to the strict rules that govern the diversity, quality, maturity, liquidity and other features of securities that money market funds may purchase. Under normal circumstances, the fund’s investments may be more susceptible than a money market fund is to credit risk, interest rate risk, valuation risk and other risks relevant to the fund’s investments. The fund does not seek to maintain a stable net asset value of $1.00 per share.

Market Risk — Financial markets rise and fall in response to a variety of factors, sometimes rapidly and unpredictably. Markets may be impacted by economic, political, regulatory, and other conditions, including economic sanctions, tariffs, and other government actions. In addition, the occurrence of global events, such as war, terrorism, environmental disasters, natural disasters and epidemics, may also negatively affect the financial markets. As with any investment whose performance is tied to these markets, the value of an investment in the fund will fluctuate, which means that an investor could lose money over short or long periods.

Management Risk — As with all actively managed funds, the fund is subject to the risk that its investment adviser and/or subadviser will select investments or allocate assets in a manner that could cause the fund to underperform or otherwise not meet its investment objective. The fund’s investment adviser and/or subadviser applies its own investment techniques and risk analyses in making investment decisions for the fund, but there can be no guarantee that they will produce the desired results.

Interest Rate Risk — Interest rates rise and fall over time. As with any investment whose yield reflects current interest rates, the fund’s yield will change over time. During periods when interest rates are low, the fund’s yield (and total return) also may be low. Changes or the anticipation of changes in interest rates also may affect the fund’s share price: a rise in interest rates generally causes the fund’s share price to fall. The longer the fund’s portfolio duration, the more sensitive to interest rate movements its share price is likely to be. Also, a change in a central bank’s monetary policy or economic conditions, among other things, may result in a change in interest rates, which could have sudden and unpredictable effects on the markets and significantly impact the value of fixed-income securities in which the fund invests. A sudden or unpredictable rise in interest rates may cause volatility and the value of fixed-income securities to decline.

Cash Transaction Risk — The fund issues and redeems shares at the fund’s NAV only in large blocks of shares (Creation Units). Purchases and redemptions of Creation Units that are made with cash, rather than through in-kind delivery of portfolio securities, may cause the fund to incur additional costs that the fund may not have incurred if the fund had made purchases or redemptions in-kind. To the extent that the transaction fees payable by the Authorized Participant do not offset the costs associated with a cash transaction, the fund’s performance may be negatively impacted.

Credit Risk — A decline in the credit quality of an issuer, guarantor or liquidity provider of a portfolio investment or a counterparty could cause the fund to lose money or underperform. The fund could lose money if, due to a decline in credit quality, the issuer, guarantor or liquidity provider of a portfolio investment or a counterparty fails to make, or is perceived as being unable or unwilling to make, timely principal or interest payments or otherwise honor its obligations.

Credit and Liquidity Enhancements Risk — The fund may invest in securities with credit or liquidity enhancements provided by a bank or other financial institution, and the existence and nature of such enhancements may be a significant factor in the investment adviser’s decision-making process. Generally, these enhancements are employed by the issuers of the securities to reduce credit risk and provide enhanced or back-up liquidity for a purchaser, such as the fund. Adverse developments affecting these banks and financial institutions could therefore have a negative effect on the value of the fund’s holdings. For example, a rating agency downgrade of a credit or liquidity enhancement provider may adversely affect the value of securities held by the fund. Any decline in the value of the securities held by the fund could cause the fund’s share price or yield to fall. To the extent that a portion of the fund’s underlying investments are enhanced by the same bank or financial institution, these risks may be increased.

Repurchase Agreements Risk — When the fund enters into a repurchase agreement, the fund is exposed to the risk that the other party (i.e., the counterparty) will not fulfill its contractual obligation. In a repurchase agreement, there exists the risk that, when the fund buys a security from a counterparty that agrees to repurchase the security at an agreed upon price (usually higher) and time, the counterparty will not repurchase the security. These risks are magnified to the extent that a repurchase agreement is

secured by collateral other than cash and government securities, such as debt securities and equity securities (Alternative Collateral). Alternative Collateral may be subject to greater price volatility and may be more volatile or less liquid than other types of collateral, increasing the risk that the fund will be unable to recover fully in the event of a counterparty’s default.

Asset-Backed Securities Risk — Asset-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. The risks of investing in asset-backed securities include, among others, interest rate risk, credit risk, prepayment risk and extension risk.

Portfolio Turnover Risk — The fund buys and sells portfolio securities actively. This may cause the fund’s portfolio turnover rate and transaction costs to rise, which may lower the fund’s performance and may increase the likelihood of capital gains distributions.

Non-U.S. Issuer Risk — The fund may invest in U.S. dollar-denominated bonds of non-U.S. corporations, governments, agencies, and supra-national entities. The fund’s investments in bonds of non-U.S. issuers may involve certain risks that are greater than those associated with investments in securities of U.S. issuers. These include risks of adverse changes in foreign economic, political, regulatory and other conditions; the imposition of economic sanctions or other government restrictions; differing accounting, auditing, financial reporting and legal standards and practices; differing securities market structures; and higher transaction costs. These risks may be heightened in connection with bonds issued by non-U.S. corporations and entities in emerging markets.

Government Securities Risk — U.S. government securities include securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), the Federal Home Loan Mortgage Corporation (Freddie Mac) or other Government-Sponsored Enterprises (GSEs)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the fund. Securities issued or guaranteed by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future. U.S. government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.

Prepayment and Extension Risk — Certain fixed-income securities are subject to the risk that the securities may be paid off earlier or later than expected, especially during periods of falling or rising interest rates, respectively. Prepayments of obligations could cause the fund to forgo future interest income on the portion of the security’s principal repaid early and force the fund to reinvest that money at the lower prevailing interest rates. Extensions of obligations could cause the fund to exhibit additional volatility and hold securities paying lower-than-market rates of interest. Either case could hurt the fund’s performance.

Liquidity Risk — The fund may be unable to sell certain securities, such as illiquid securities, readily at a favorable time or price, or the fund may have to sell them at a loss.

Securities Lending Risk — Securities lending involves the risk of loss of rights in, or delay in recovery of, the loaned securities if the borrower fails to return the security loaned or becomes insolvent.

Concentration Risk — To the extent that the fund’s portfolio is concentrated in the securities of issuers in a particular market, industry, group of industries, sector or asset class, the fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more vulnerable to adverse economic, market, political or regulatory occurrences affecting that market, industry, group of industries, sector or asset class.

Financials Sector Risk — Because the fund’s investments are concentrated in issuers doing business in the financials sector, the companies in which the fund invests will be affected by many of the same factors, such as legislative or regulatory changes, intense competition for market share and other competitive challenges. In addition, securities issued by companies in the financials sector may underperform other segments of the debt market as a whole and are likely to have above-average volatility.

Market Trading Risk — Although fund shares are listed on national securities exchanges, there can be no assurance that an active trading market for fund shares will develop or be maintained. If an active market is not maintained, investors may find it difficult to buy or sell fund shares.

Shares of the Fund May Trade at Prices Other Than NAV — Fund shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of the shares of the fund will approximate the fund’s net asset value (NAV), there may be times when the market price and the NAV vary significantly. An investor may pay more than NAV when buying shares of the fund in the secondary market, and an investor may receive less than NAV when selling those shares in the secondary market. The market price of fund shares may deviate, sometimes significantly, from NAV during periods of market volatility or market disruption.
