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 3 will have its requirement (at the clearing member rates) calculated at $1,000 starting on Tuesday, August 30, 2005.
| One Long Tier 1 HO | (1 * $5,500) | = | $5,500 |
| One Short Tier 3 HO | (1 * $4,750) | = | $4,750 |
| Net Scan Risk | ($5,500-$4,750) | = | $750 |
| Spread Rate | (1* $ 250) | = + | $250 |
| Total Requirement | = | $1,000 |
| Summary | |
| Clearing Member (Maintenance Margin): | $1,000 |
| Member Customer (Initial Margin): | $1,100 |
| Non-Member Customer (Initial Margin): | $1,350 |
