| Current systems calculate the margin requirement for spread positions
by first determining the "Scan Risk" and then multiplying the
number of spreads by a rate set by the Exchange. Scan Risk is determined
by netting the outright margin required for each leg of a spread. Spreading
between differently margined contracts results in a higher spread margin
than between equally margined contracts. Below is provided an example where
the legs of a spread are margined differently. |
| Scan Risk Example at Clearing Member Rates |
A spread consisting of one NG leg in Tier 1 and another in
Tier 2 will have its requirement (at the clearing member rates) calculated
at $1,500 starting on Wednesday, December 18, 2002.
