SEBI Chairman, C B Bhave, on Saturday said that there were two procedures at work with relation to the Satyam scam, apart from criminal proceedings.

"There are two proceedings going on. SEBI started proceedings against the promoters and some of the officials of the company. We have issued show-cause notices to the auditors," Bhave told reporters here today.

SEBI had issued show-cause notices to audit firms including the Indian arm of global audit firm PricewaterhouseCoopers, after the scam came to light.

"Apart from this, criminal cases have been filed by CBI," he said.

Recently, a high-powered committee of the Institute of Chartered Accountants of India (ICAI) had recommended strict disciplinary action against four Hyderabad-based audit firms for their involvement in the Satyam scam.

It has suggested regulatory action against Krishna & Prasad, Rao & Shyam, P Viswanath & Associates and GMK Associates. The Indian arm of PriceWaterhouseCoopers is undergoing a probe for its role as well.

The Satyam scam which rocked the Indian corporate world a year ago is estimated at Rs 14,000 crore, the CBI has said in its charge sheet.

Satyam's former Chairman, B Ramalinga Raju, who is in jail, has admitted to cooking up the company's books or accounts to the tune of Rs 6,000-crore.
