October 2018 Supplement to the Options Disclosure Document

The SEC approved the October 2018 supplement to the Options Disclosure Document (ODD). The ODD contains general disclosures on the characteristics and risks of trading standardized options. The October 2018 supplement (i) amends and restates in its entirety the April 2015 Supplement, which accommodated foreign index options and certain implied volatility index options;2 (ii) provides additional contract adjustment disclosures regarding the determination of contract adjustments by OCC rather than adjustment panels and the manner in which certain adjustments may affect an option’s value; and (iii) reflects T+2 settlement. As with other supplements to the ODD, this should be read in conjunction with the current ODD, Characteristics and Risks of Standardized Options.
