That article notes that signing those documents may have been a winding down process. I would be willing to be that between 1999-2002 Bain had more than those few SEC filings. In fact, I would think the one dated April 13, 1999 would not be a big deal because he probably did have a lot of information on that form.
I will agree there is a grey area in the time frame from 1999-2002, but I do not think he was involved in the day-to-day activities of Bain. He very well may have been involved in some of the larger issues at Bain.
Here is a question, the SEC filings at Bain are, for the most part, public forms. Why would Mitt lie and say he took a leave of absence in 1999? When he, or someone in his campaign, has to know that people are going to search the Bain SEC filings?
Where is the hardcore evidence that Mitt was involved heavily in the day-to-day details of the CEO of Bain? In the other post I listed out possible reasons why he may have stuck on. However, if he was heavily involved in the day-to-day activities of Bain and was able to do all the work he did for the Salt Lake City he deserves some kind of medal because he probably did not get any sleep at all.
