March 13, 2009 Market Credit Risk Standard Meeting

  • Consensus reached on MCRS with the following caveats (next page)


Consensus recommendations for the mcrs
Consensus Recommendations for the MCRS

  • ERCOT will modify the MCRS to bifurcate all scenarios > 99% as a new bullet titled “large impact stress scenarios” to clearly delineate that these runs represent “black swan” events

  • ERCOT will revise the MCRS to incorporate previous CWG recommendation to have an entity that is relying on a guarantor, to take on the rating of the guarantor, up to the amount of the guaranty

    • previously the unrated entity would take the midpoint between the guarantors rating and CCC+

    • Presently the models engine will not allow for this and Staff is investigating what is needed to run the model with the revised methodology

  • ERCOT will provide the MCWG with its plan to manage the MCRS, including plans for staffing with persons with the requisite skill set in financial engineering

  • ERCOT will report back to MCWG on the feasibility of running the MCRS on a frequency greater than quarterly

  • ERCOT will run a simulation of the MCRS using the present methodology and the revised methodology for entities providing a guarantor, for the same period, to demonstrate the difference from applying the different methodologies

  • ERCOT will publish the detail components of the MCRS engine as a procedure document for stakeholders
