“Companies are under pressure from investors to get the best auditor they can,” said Paul Gillis, an accounting professor at Peking University in Beijing. More than 200 Chinese companies are listed on U.S. exchanges, and hundreds more trade on over-the-counter bulletin boards. In the last five months, at least 15 have upgraded to a Big Four auditor — Deloitte, Ernst & Young, PricewaterhouseCoopers or KPMG — from a smaller firm, according to an analysis from Audit Analytics.
