As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise.

Fund Risks:

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise.

Mortgage and Asset-Backed Securities Risk. The Fund may invest in mortgage- and asset-backed securities, which represent “pools” of mortgages or other assets, including consumer loans or receivables held in trust. In a period of rising interest rates, these securities may exhibit additional volatility.

Preferred Stock Risk. A preferred stock may decline in price, or fail to pay dividends when expected, because the issuer experiences a decline in its financial status.

Derivatives Risk. A derivative is an instrument with a value based on the performance of an underlying currency, security, index or other reference asset. The use of derivatives involves risks different from, or greater than, the risks associated with investing in more traditional investments. Derivatives involve costs, may create leverage, and may be illiquid, volatile, and difficult to value.

Investments involve risk. Principal loss is possible.
