Mitt says he left Bain in 1999. Newts PAC says he filed SEC papers saying he left 2001. Romney is still getting 10 million a year in profits participation from Bain. He was able to get this deal when he left.
Thus he is still profiting from Bain’s portfolio of acquisitions. The good, the bad and the ugly. More ammunition for David Axelrod and his Jug Eared creation.
This is why he is hiding his tax returns until he absolutely has the nomination sewn up, or if he loses the nonination his wealth trough stays private.
