The S&P Composite 1500 Dynamic Rebalancing Risk Control Index is designed to respond to the volatility of the S&P 1500 Index. The S&P 1500 Index is a composite index of the S&P 500 Index, S&P 400 Index and S&P 600 Index, which are composed of stocks representing the large capitalization, mid capitalization and small capitalization segments of the U.S. equity market, respectively. The Index is composed of equity securities of the S&P 1500 Index (the “Stock Component”) and fixed income securities, including U.S. Treasury Bills (the “Cash Component”). The Index responds to volatility by establishing a specific volatility target that adjusts the Index’s components among an allocation to the Stock Component and the Cash Component based upon realized exponentially-weighted historical volatility of the S&P 1500 Index. The exponentially-weighted historical volatility calculation weights the more recent historical periods more heavily than older periods. As these volatility targets are met, the Index may be rebalanced as frequently as daily.
