Each Index within the BlackRock Rate Hedged Series of Indices (the “Series”) provides exposure to a specific Fixed Income ETF, while seeking to minimize the Interest Rate or Inflation exposure of the constituents of the ETF. Through a rules-based approach, each Index will hold up to 10 Interest Rate or Inflation Swaps, whose weights are dynamically updated daily.  In addition, each Index will also hold a cash position that is intended to reflect the collateral that must be held to manage the swaps positions by any fund tracking the Index.
