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 NG leg in Tier 1 and another in Tier 5 will have its requirement (at the clearing member rates) calculated at $9,500 starting on Monday, December 12, 2005.
| One Long Tier 1 NG | (1 * $15,500) | = | $15,500 |
| One Short Tier 5 NG | (1 * $ 7,000) | = | $7,000 |
| Net Scan Risk | ($15,500-$7,000) | = | $8,500 |
| Spread Rate | (1* $ 1000) | = + | $1,000 |
| Total Requirement | = | $9,500 | |
| Summary | |||
| Clearing Member (Maintenance Margin): | $9,500 | ||
| Member Customer (Initial Margin): | $10,450 | ||
| Non-Member Customer (Initial Margin): | $12,825 |
