Good DD and analysis. Only one thing that needs to be brought out is that Mr. Otterbach did not purchase his shares but, rather, was awarded them. I don't have the SEC form in front of me but I remember a "back-and-forth" in which I was involved which discussed whether his shares were purchased or awarded. It was determined they were awarded.
GLTA!!

Oh boy, when you're dead
You don't take nothing with you
But your soul - think!
