| There are risks involved with investing in ETFs, including possible loss of money. Shares are not actively managed and are subject to risks including those regarding short selling and margin maintenance requirements. Ordinary brokerage commissions may apply. |
| Shares are not individually redeemable and owners of the shares may acquire those shares from the Fund and tender those shares for redemption to the Fund in Creation Unit aggregations only, typically consisting of 100,000 shares. |
| The value of convertible securities tends to vary with fluctuations in the market value of the underlying securities. Convertible securities are subject to the risk of default by the issuer. |
| The Fund may invest in fixed-income securities, such as notes and bonds, which carry interest rate and credit risk. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise and vice versa. Credit risk is the risk of loss on an investment due to the deterioration of an issuer's financial health. |
| The Fund's underlying securities may be subject to call risk, which may result in the Fund having to reinvest the proceeds at lower interest rates, resulting in a decline in the Fund's income. |
| Non-investment grade securities have additional risks, including higher default risk and decreased market liquidity. |
| The Fund's use of a representative sampling approach will result in its holding a smaller number of securities than are in the underlying Index, and may be subject to greater volatility. |
| The Fund is considered non-diversified and may be subject to greater risks than a diversified fund. |
| Foreign securities have additional risks, including exchange-rate changes, decreased market liquidity, political instability and taxation by foreign governments. |
