Professional Conduct Investigation

So I’m not sure how much information I can really give about this but I will do my best. I haven’t taken any exams but I did register for the CFA many years ago, just never got around to sitting for an exam. Several years ago I settled a matter with the SEC but there was no discipline other than a large fine and disgorgement but the matter doesn’t show me in a good light.

Well, just recently I decided I wanted to take L1 but apparently the CFA found out and have launched a professional conduct inquiry. They’ve asked me to complete a form with a whole bunch of questions about the matter and I’m honestly not sure how I feel about that.

So my question is do I have any options? Do I have to complete the form? Can I simply respond that the matter was settled without any admission of wrongdoing?

Appreciate any thoughts.
