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 6 will have its requirement (at the clearing member rates) calculated at $2,000 starting on Friday, July 9, 2004.

One Long Tier 1 JM (1 * $3,000)
=
$3,000
One Short Tier 6 JM (1 * $1,500)
=
$1,500
Net Scan Risk ($3,000-$1,500)
=
$1,500
Spread Rate (1* $ 500)
