In response to the changing dynamics of the energy marketplace, NYMEX will utilize a tier margin methodology for calculating outright (Scan) margin requirements for the NYMEX Heating Oil and New York Harbor Heating Oil Calendar Swap Contracts. This methodology has been in place for several years for the NYMEX Natural Gas and PJM Electricity Contracts. Moreover, this allows NYMEX to effectively capture the appropriate risk exposure based on the product’s forward curve. Accordingly, presented below are the initial Scan tier descriptions and respective margin requirements for the NYMEX Heating Oil and New York Harbor Heating Oil Calendar Swap Contracts.

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 $500 starting on Friday, September 24, 2004.

One Long Tier 1 HO (1 * $3,500)
=
$3,500
One Short Tier 2 HO (1 * $3,250)
=
$3,250
Net Scan Risk ($3,500-$3,250)
=
