FlexShares US Quality Low Volatility Index Fund

The underlying index is designed to construct a high-quality universe of companies, that in aggregate, possess lower overall absolute volatility characteristics relative to the Northern Trust 1250 Index (the “Parent Index”), a float-adjusted market capitalization weighted index of U.S. domiciled large- and mid-capitalization companies. Under normal circumstances, the fund will invest at least 80% of its total assets in the securities of the underlying index.
