In 1997, Romney set up a Bermuda-based entity called Sankaty High Yield Asset Investors Ltd., that has been described in securities filings as "a Bermuda corporation wholly owned by W. Mitt Romney." The entity was transferred to his wife's blind trust on Jan. 1, 2003, the day before Romney was inaugurated as governor of Massachusetts. The director and president of the entity is the Romneys personal lawyer R. Bradford Malt, who also oversees the blind trust. Romney did not list it on financial disclosures until his 2010 tax return, but Shaxson writes that, "even after examining the return,we have no idea what is in this company, but it could be valuable, meaning that it is possible Romney's wealth is even greater than previous estimates."
Romney has personal interests in at least 12 Bain funds in the Cayman Islands, worth as much as $30 million. Shaxson reports that "the Romney campaign insists he saves no tax by using them, but there is no way to check this."
A $3 million Swiss bank account appeared on Romney's 2010 returns, but disappears on the 2011 returns, after the Romneys trustee closed it. USC tax law professor Ed Kleinbard told Shaxson that the Swiss account "has political but not tax-policy resonance" because it was essentially a bet against the U.S. dollar.
The Romneys' I.R.A.'s have been receiving profit interest from Cayman Island-based Bain Capital funds that were set up long after Romney left the firm in 1999. Shaxson writes that although firms are technically only supposed to do this if the compensation is for past services, tax law experts say that Romney "can get away with it because of excessive 'administrative indulgences' that have allowed a 'perversion of the law in favor of a small class of overcompensated investment managers.'"
Romney's I.R.A. appears to have invested in "blocker corporations" located in tax havens like the Cayman Islands, which are designed to make it easier to avoid U.S. business taxes.
Shaxson also suggests that, under Romney, Bain Capital may have helped wealthy foreign investors take advantage of special U.S. tax exemptions. He writes that investors in Romney's first Bain Capital Fund, in 1984, included "newspaper tycoon, tax evader, and fraudster Robert Maxwell, who fell from his yacht, and drowned, off of the Canary Islands in 1991 in strange circumstances, after looting his company's pension fund," "Eduardo Poma, a member of one of the '14 families' oligarchy that has controlled most of El Salvador's wealth for decades," "a Geneva-based trustee overseeing a trust that invested $2.5 million, a Bahamas corporation that put in $3 million, and three corporations in the tax haven of Panama."

He was also, there is no doubt, a spy, although who exactly he spied for is a more complicated matter. Because of his many business interests in Eastern Europe, and those fawning biographies of dictators, he was able to move freely through the Communist world. After he died, then Prime Minister John Major said Maxwell had given him "valuable insights" into the situation in the Soviet Union. However, it seems very likely that Maxwell was allowing information to flow in both directions, bringing news of the West into the Soviet bloc, along with his business deals and bonhomie.
