PricewaterhouseCoopers (PwC), which was mandated to do the forensic audit on Multi Commodity Exchange, is expected to submit its second report soon. The first report, which was submitted last month, went into the financial details of the exchange since its inception in 2003 and highlighted major discrepancies. The commodity market regulator Forward Markets Commission had ordered for the audit on the exchange after National Spot Exchange, part of MCX group, defaulted on trade settlement worth Rs. 5,600 crore. "The terms of reference provided for the PwC audit was comprehensive and it has covered only a few points in the first report," said a highly placed source who did not want to be identified. It is learnt that there may be one or two more reports from PwC. The second report may broadly cover the aspect of risk management followed by the exchange and financial transactions between MCX and the Indian Bullion Market Association, the subsidiary of scam-hit National Spot Exchange.
