On a January afternoon in George Town, the capital of the Cayman Islands, the sun beats down on three cruise ships anchored at Hog Sty Bay. Along the waterfront on Church Street stands a five-story office building called Ugland House.
From the outside, there's no way to see it's the official address of 12,748 companies. Ugland and other office buildings in George Town are home to subsidiaries of more than 150 U.S. corporations, including Coca-Cola Co., Intel Corp. and 10 more of the 30 companies in the Dow Jones Industrial Average.
