"Stepping down" can also be code phrase for "avoiding legal action" - I guess technically it's more like cashing in your chips while you're ahead. The Enron execs didn't take the hint and got pummelled with not only civil but criminal litigation. Maybe Rick is predicting an investigation and wants to cut ties to avoid association with the mobsters up in Michigan (or Washington). Anyway, I'd like to hear someone with a legal background chime in on whether a suit against a corporation (let's say GM) can include officers who severed ties with the corporation prior to a) the infraction date or b) the severance date.
Disclaimer - I'm not an exec in any corporation and am not trying to seek free legal advice to get myself out of a dilemma
