ReasonThe existing Protocol methodology for computing exposure does not reflect the market risk profile of trading Counter-Parties that represent neither Load nor generation. In addition, under existing calculations, in certain circumstances Counter-Parties with neither Load nor generation may not have an MCE while continuing to operate in the Market.

Summary
This Nodal Protocol Revision Request (NPRR) revises the calculation of credit exposure for Counter-Parties that represent neither Load nor generation by adjusting the M1 factor for forward exposure risk to reflect the fact that these Counter-Parties do not have Mass Transition risk, reducing the 40-day "look back" period for certain exposure components to 20 days and specifying a Minimum Current Exposure (MCE) for these Counter-Parties that is also used as the Initial Estimated Liability.
