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 3 will have its requirement (at the clearing member rates) calculated at $ 2,500 starting on Monday, January 29, 2007.
| One Long Tier 1 NG | (1 * $ 7,500) | = | $7,500 |
| One Short Tier 3 NG | (1 * $ 6,000) | = | $6,000 |
| Net Scan Risk | ($7,500 - $6,000) | = | $1,500 |
| Spread Rate | (1* $ 1,000) | = + | $1,000 |
| Total Requirement | = | $2,500 | |
| Summary | |||
| Clearing Member (Maintenance Margin): | $2,500 | ||
| Member Customer (Initial Margin): | $2,750 | ||
| Non-Member Customer (Initial Margin): | $3,375 |
