The Las Vegas, Nevada office of PricewaterhouseCoopers resigned April 23 as auditor of casino company Las Vegas Sands, according to an SEC filing. PwC has been signing the opinion for Las Vegas Sands since its IPO in 2004. A Wall Street Journal anonymous source says “the legal and regulatory scrutiny of Las Vegas Sands was “the overriding issue” behind PwC’s resignation. Personal tension between Mr. Adelson and the accounting firm also played a role.” An LVS spokesperson told the Wall Street Journal PwC worked for LVS Chairman and CEO Sheldon Adelson for twenty-five years.
