It’s been previously debunked
Mitt Romney and his departure from Bain

We have looked at this issue before, back in January, and thought we had settled it.

But now the Boston Globe has raised the issue again. The story seems to hinge on a quote from a former Securities and Exchange Commission member, which would have more credibility if the Globe had disclosed she was a regular contributor to Democrats. (Interestingly, “The Real Romney,” a book on the former Massachusetts governor, by Boston Globe reporters, states clearly that he left Bain when he went to run the Olympics and details the turmoil that ensued when he suddenly quit, nearly breaking up the partnership)

We’re considering whether to once again take a deeper look at this, though it really feels like Groundhog Day again. There appears to be some confusion about how partnerships are structured and managed, or what SEC documents mean. (Just because you are listed as an owner of shares does not mean you have a managerial role.)

To accept some of the claims, one would have to believe that Romney, with the advice of his lawyers, lied on government documents and committed a criminal offense. Moreover, you would have to assume he willingly gave up his share to a few years of retirement earnings — potentially worth millions of dollars — so he could say his retirement started in 1999.
…
The part about lying to the SEC is absurd, since the SEC doesn’t require an owner to be the operational decision-maker (Romney delegated such responsibilities, as is his right).
