In big shake-up Accounting Firm Ernst & Young evaluating worldwide audit business split 

Big Four accounting firm Ernst & Young is considering a world-wide split of its audit and advisory businesses

A split would be the biggest structural change at a Big Four firm since Arthur Andersen fell apart

How exactly the restructuring would work isn’t clear. The split could bolt some services, such as tax advice

The decision comes amid regulatory scrutiny of potential conflicts of interest in the profession

With the big move, which will create two giants, an audit-focused arm will be set up

It earned a revenue of $40 billion, according to the Wall Street Journal report

Chief Executive Carmine Di Sibio, as per news agency Reuters, revealed the details on Thursday
