FlexShares Ready Access Variable Income Fund is actively managed and does not seek to replicate a specified index. Additionally, the Fund may invest without limitation in the fixed income and debt securities of foreign issuers in both developed and emerging markets. The Fund is at increased credit and default risk, where there is an inability or unwillingness by the issuer of a fixed income security to meet its financial obligations, debt extension risk, where an issuer may exercise its right to pay principal on an obligation later than expected, as well as interest rate/maturity risk, where the value of the Fund's fixed income assets will decline because of rising interest rates. The Fund may also be subject to increased concentration risk as it may invest more than 25% of its assets into the securities of a single developed market. Additionally, the Fund may invest without limitation in mortgage or asset-backed securities, which puts it at increased risk for interest rate/maturity risk, debt extension risk, and prepayment (or call) risk. Also, the Fund is "non-diversified" under the Investment Company Act of 1940, and may invest more of its assets in fewer issuers than diversified funds.
