Investors buying or selling fund shares on the secondary market may incur customary brokerage commissions. Market prices may differ to some degree from the net asset value of the shares. Investors who sell fund shares may receive less than the share's net asset value. Shares may be sold throughout the day on the exchange through any brokerage account. However, unlike mutual funds, shares may only be redeemed directly from a fund by authorized participants in very large creation/redemption units. If a fund’s authorized participants are unable to proceed with creation/redemption orders and no other authorized participant is able to step forward to create or redeem, fund shares may trade at a discount to a fund’s net asset value and possibly face delisting.

A fund’s shares will change in value, and you could lose money by investing in a fund. One of the principal risks of investing in a fund is market risk. Market risk is the risk that a particular stock owned by a fund, fund shares or stocks in general may fall in value. There can be no assurance that a fund’s investment objective will be achieved. The outbreak of the respiratory disease designated as COVID-19 in December 2019 has caused significant volatility and declines in global financial markets, which have caused losses for investors. While the development of vaccines has slowed the spread of the virus and allowed for the resumption of "reasonably" normal business activity in the United States, many countries continue to impose lockdown measures in an attempt to slow the spread. Additionally, there is no guarantee that vaccines will be effective against emerging variants of the disease.

In managing a fund’s investment portfolio, the portfolio managers will apply investment techniques and risk analyses that may not have the desired result.

Companies that issue loans tend to be highly leveraged and thus are more susceptible to the risks of interest deferral, default and/or bankruptcy. 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. The senior loan market has seen a significant increase in loans with weaker lender protections which may impact recovery values and/or trading levels in the future.

A fund that effects all or a portion of its creations and redemptions for cash rather than in-kind may be less tax-efficient.

Covenant-lite loans contain fewer maintenance covenants than 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. This may hinder a fund’s ability to mitigate problems and increase a fund’s exposure to losses on such investments.

As the use of Internet technology has become more prevalent in the course of business, funds have become more susceptible to potential operational risks through breaches in cyber security.

Certain securities are subject to call, credit, inflation, income, interest rate, extension and prepayment risks. These risks could result in a decline in a security’s value and/or income, increased volatility as interest rates rise or fall and have an adverse impact on a fund’s performance.

Financial services companies are subject to the adverse effects of economic recession, government regulation, decreases in the availability of capital, volatile interest rates, and competition from new entrants in their fields of business.

The market value of floating rate securities may fall in a declining interest rate environment and may also fall in a rising interest rate environment if there is a lag between the rise in interest rates and the reset. Income earned by a fund on floating rate and fixed-to-floating rate securities may decline due to lower coupon payments on floating-rate securities.

High yield securities, or “junk” bonds, are less liquid and are subject to greater market fluctuations and risk of loss than securities with higher ratings, and therefore, are considered to be highly speculative.

A fund may be a constituent of one or more indices or models which could greatly affect a fund’s trading activity, size and volatility.

To the extent a fund invests in floating or variable rate obligations that use the London Interbank Offered Rate (“LIBOR”) as a reference interest rate, it is subject to LIBOR Risk. The United Kingdom’s Financial Conduct Authority, which regulates LIBOR, will cease making LIBOR available as a reference rate over a phase-out period that will begin immediately after December 31, 2021. The unavailability or replacement of LIBOR may affect the value, liquidity or return on certain fund investments and may result in costs incurred in connection with closing out positions and entering into new trades. Any potential effects of the transition away from LIBOR on a fund or on certain instruments in which a fund invests can be difficult to ascertain, and they may vary depending on a variety of factors, and they could result in losses to a fund.

Certain fund investments may be subject to restrictions on resale, trade over-the-counter or in limited volume, or lack an active trading market. Illiquid securities may trade at a discount and may be subject to wide fluctuations in market value.

Large inflows and outflows may impact a new fund’s market exposure for limited periods of time.

A fund classified as “non-diversified” may invest a relatively high percentage of its assets in a limited number of issuers. As a result, a 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.

A fund and a fund's advisor may seek to reduce various operational risks through controls and procedures, but it is not possible to completely protect against such risks.

A fund with significant exposure to a single asset class, country, region, industry, or sector may be more affected by an adverse economic or political development than a broadly diversified fund. Trading on the exchange may be halted due to market conditions or other reasons. There can be no assurance that the requirements to maintain the listing of a fund on the exchange will continue to be met or be unchanged.

A fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. There is no assurance that a fund could sell or close out a portfolio position for the value established for it at any time.

A fund may invest in securities that exhibit more volatility than the market as a whole.
