The underlying index is comprised of U.S. dollar denominated high yield corporate bonds that have been selected in accordance with a rules-based methodology that seeks to identify securities that, in the aggregate, are expected to have lower volatility relative to the broad U.S. dollar denominated high yield corporate bond market.
