As per the normal review of market volatility to ensure adequate collateral coverage, CME Group Performance Bond staff approved volatility scan range changes for the following products listed below. The Volatility Scan range is the amount by which the implied volatility levels are changed for each option during the Span margining process. For those Span margin scenarios that have implied volatility changes, the current implied volatility is moved either up or down by the amount of the Volatility Scan Range. For a futures-only portfolio, the Volatility Scan Range will have no effect. The rates will be effective with the launch of these products on Monday, August 18, 2008.
