† Ratings are based on S&P, Moody's or Fitch, as applicable. A credit rating is an assessment provided by a nationally recognized statistical rating organization (NRSRO) of the creditworthiness of an issuer with respect to debt obligations, including specific securities, money market instruments or other debts. Ratings are measured on a scale that generally ranges from AAA (highest) to D (lowest); ratings are subject to change without notice. NR indicates the debtor was not rated, and should not be interpreted as indicating low quality. If securities are rated differently by the rating agencies, the higher rating is applied. For more information on the rating methodology, please visit the following NRSRO websites: standardandpoors.com and select 'Understanding Ratings' under Rating Resources on the home page; moodys.com and select 'Rating Methodologies' under Research and Ratings on the home page; fitchratings.com and select 'Ratings Definitions' on the home page.

There are risks involved with investing in ETFs, including possible loss of money. Shares are not actively managed and are subject to risks similar to those of stocks, including those regarding short selling and margin maintenance requirements. Ordinary brokerage commissions apply. The Fund’s return may not match the return of the Underlying Index. The Fund is subject to certain other risks. Please see the current prospectus for more information regarding the risk associated with an investment in the Fund.

Investments focused in a particular industry or sector are subject to greater risk, and are more greatly impacted by market volatility, than more diversified investments.

Interest rate risk refers to the risk that bond prices generally fall as interest rates rise and vice versa.

An issuer may be unable to meet interest and/or principal payments, thereby causing its instruments to decrease in value and lowering the issuer’s credit rating.

The Fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities.

Obligations issued by US Government agencies and instrumentalities may receive varying levels of support from the government, which could affect the fund’s ability to recover should they default.

Mortgage- and asset-backed securities, which are subject to call (prepayment) risk, reinvestment risk and extension risk. These securities are also susceptible to an unexpectedly high rate of defaults on the mortgages held by a mortgage pool, which may adversely affect their value. The risk of such defaults depends on the quality of the mortgages underlying such security, the credit quality of its issuer or guarantor, and the nature and structure of its credit support.

The Fund may invest in privately issued securities, including 144A securities which are restricted (i.e. not publicly traded). The liquidity market for Rule 144A securities may vary, as a result, delay or difficulty in selling such securities may result in a loss to the Fund.

Reinvestment risk is the risk that a bond's cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond.

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.

Beta is a measure of risk representing how a security is expected to respond to general market movements. PureBeta is a market-capitalization weighted methodology, and in no way refers to the purity or absence of errors or flaws in the Underlying Index’s methodology or of the Fund in seeking to track the investment results of the Underlying Index.
