How Do I Add More Information About The Transaction I Am Reporting?

You can add additional information in the ‘Remarks’ field. If you do not want the additional information to be public, use the ‘Private remarks to securities regulatory authority’. To the extent that more space is needed, you may wish to consider cross-referencing a document already publicly disclosed that has this information, such as a press release or a material change report.
