The number of lawsuits against Chinese reverse merger companies nearly tripled since 2010, according to a study by Stanford Law School Securities Class Action Clearinghouse and Cornerstone Research. "Securities Class Action Filings: 2011 Mid-Year Assessment," reports that 24 class action lawsuits were filed against Chinese reverse merger companies in 2011. Reverse mergers work as follows: a Chinese business is acquired by an American shell company that is publicly traded. The board then resigns, a Chinese-appointed board takes control and changes the company name. Voila: it now can issue new stock to investors, all without IPO costs and paperwork.
