When Should I Register as an Insider?

If you are a reporting insider, you should register as an insider if you will be filing an insider profile and insider reports only for yourself and no one else.

If you are filing insider profiles and insider reports for one or more reporting insiders (other than yourself), or information for several issuers you should register as an agent (see question 2.1.7), and not as an insider.
