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 CL leg in December 2007 and another CL in January 2008 will have its requirement (at the clearing member rates) calculated at $1,150 starting on Tuesday, October 30, 2007.

One Long November 2007 CL (1 * $ 4,750) = $4,750
One Short December 2007 CL (1 * $ 4,000) = $4,000
Net Scan Risk ($4,750-$4,000) = $   750
Spread Rate (1* $ 400) = + $   400
Total Requirement   = $1,150
       
Summary      
Clearing Member (Maintenance Margin):     $1,150
Member Customer (Initial Margin):     $1,265
Non-Member Customer (Initial Margin):     $1,553
