We encourage you to submit your comments. The Technical Advisory Board (TAB) will review and consider all comments and proposed changes. Based on participants' input, modifications may be made to the Part B to which a proposal was made and/or to improve the SM Transparency Report Framework, Part A. In the future, should a Part B require additional rules, this same process can be implemented and the Part B updated.

To create a Part B, get started by submitting a Part B request form:
