What Do I Do If I Have Been Previously Filing Insider Reports But Am No Longer Required To?

You should add a comment in the “Remarks” field explaining that you are no longer a reporting insider or are exempt. You can do this either on your next transaction to be filed on SEDI or by amending your last report already filed on SEDI. A member of the public viewing your insider reports on SEDI will then know why you have ceased reporting.
