A new Reuters investigative report takes a deeper look at a niche industry of advisers who specialize in so-called “reverse merger” deals that use shell companies to give clients easy entry into U.S. capital markets. As correspondents Nanette Byrnes and Lynnley Browning report, more than 400 Chinese companies have been listed in the U.S. over the course of the last decade by way of this back-door method. But, as their investigation shows, a recent “spate of spectacular collapses of Chinese stocks listed on American exchanges has cost U.S. investors billions of dollars” and sparked multiple investigations into the practice.
