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 JM leg in Tier 1 and another in Tier 4 will have its requirement (at the clearing member rates) calculated at $3,500 starting on Friday, April 11, 2003.
One Long Tier 1 JM (1 * $3,500)
=
$3,500
One Short Tier 4 JM (1 * $2,000)
=

$2,000
Net Scan Risk ($3,500-$2,000)

Spread Rate (1* $2000)
