Sankaty High Yield Asset Investors Ltd., Bermuda

Romney got more than $2 million in income from Bain in June. "The firm today has at least 138 funds organized in the Cayman Islands, and Romney himself has personal interests in at least 12, worth as much as $30 million, hidden behind controversial confidentiality disclaimers," Shaxson writes. Romney's campaign has repeatedly pointed out that he quit the firm in February 1999, but his ties to the firm lasted beyond that date. Sankaty High Yield Asset Investors Ltd., an entity based in Bermuda, was set up in 1997 and transferred to Ann Romney's blind trust in January 2003. In securities filings, it's called "a Bermuda corporation wholly owned by W. Mitt Romney," but Romney failed to disclose it on several financial disclosure forms until he listed it on his 2010 tax return. However, his tax return did have 55 pages detailing transactions with foreign entities. Romney's blind trusts don't seem all that blind: They've invested $10 million in Solamere Founders Fund, which was founded by their son Tagg and former campaign fundraiser Spencer Zwick. The manager of the trust is Romney's personal lawyer and he says he invested the Romneys' money in Solamere without consulting them.
