December 2009 Supplement to the Options Disclosure Document

On December 10, 2009, the SEC approved a supplement to the Options Disclosure Document (www.optionsclearing.com/components/docs/December_2009_ODD_Definitive_Supplement.pdf) (ODD). The ODD contains general disclosures on the characteristics and risks of trading standardized options. The recently approved supplement adds disclosure regarding the characteristics and special risks of dividend index options. The supplement also adds disclosure stating that the options markets may use methods other than those specified in the ODD to set exercise prices. As with other supplements to the ODD, this should be read in conjunction with the current ODD entitled Characteristics and Risks of Standardized Options (www.optionsclearing.com/components/docs/riskstoc.pdf). This supplement supersedes and replaces the September 2008 supplement to the ODD, which relates to selected index options, as described in Information Notice 11/12/08.
