Fair enough, but then there's Cain's assertion that, if there was a payoff, he was unaware of it. For the CEO of the organization to claim that he was unaware of the resolution of a complaint involving himself, involving money paid out, is far harder to believe than the original allegations.
It is most likely it was not the company that handled the payout. In cases like this it is the company’s insurance that handles these matters. It could be viewed as improper by share holders or the board of directors for a CEO to be involved in a settlement where he is the accused.
