January 2011 Supplement to the Options Disclosure Document

The SEC approved a supplement to the Options Disclosure Document (ODD) on January 12, 2011. The ODD contains general disclosures on the characteristics and risks of trading standardized options. The recently approved January 2011 Supplement amends and restates the June 2007 Supplement to provide disclosure to accommodate the listing of credit default options that contemplate only a single credit event, and to incorporate certain technical amendments. As with other supplements to the ODD, this should be read in conjunction with the current ODD, Characteristics and Risks of Standardized Options.
