While in private business, Mitt Romney utilized shell companies in two offshore tax havens to help eligible investors avoid paying U.S. taxes, federal and state records show.

Romney gained no personal tax benefit from the legal operations in Bermuda and the Cayman Islands. But aides to the Republican presidential hopeful and former colleagues acknowledged that the tax-friendly jurisdictions helped attract billions of additional investment dollars to Romney's former company, Bain Capital, and thus boosted profits for Romney and his partners.
 

Investing through what's known as a blocker corporation in Bermuda protects tax-exempt American institutions, such as pension plans, hospitals and university endowments, from paying a 35% tax on what the Internal Revenue Service calls "unrelated business income" from domestic hedge funds that invest in debt, experts say.

Hmmm, lots more of interest in report. But, don't get too excited, it's all legal.
