Notice Number | 05-186
Effective Date |
At its July 27, 2005 meeting, the Clearing House Risk Committee approved changes to the methodology used to calculate security deposits. The volume component of the security deposit will now be calculated based on risk-weighted volume for all products. Previously, only the full-sized equity contract volume was risk-weighted, with all other volume being treated equally. These changes will be effective for the determination of third quarter security deposit requirements in October. For the full text of this advisory . . .
