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 HO leg in Tier 1 and another in Tier 2 will have its requirement (at the clearing member rates) calculated at $ 750 starting on Wednesday, May 21, 2008.

One Long Tier 1 HO (1 * $ 9,000) = $9,000
One Short Tier 2 HO (1 * $ 8,500) = $8,500
Net Scan Risk ($ 9,000-$ 8,500) = $500
Spread Rate (1* $ 250) = + $250
Total Requirement   = $750
       
       
Summary      
Clearing Member (Maintenance Margin):     $750
Member Customer (Initial Margin):     $825
Non-Member Customer (Initial Margin):     $1,013
