Mumbai, Jan 26 (Agencies): Market regulator Sebi has sought fresh clarifications on the proposed USD 9.6 billion Vedanta-Cairn deal, which has already been awaiting clearance from the Securities and Exchange Board of India (Sebi) market regulator for about six months now.

According to sources, the market regulator has asked for more clarifications from the merchant banker involved in the planned Cairn-Vedanta deal. It could not be ascertained as to what are the new clarifications being sought by Sebi.

Vedanta group had sought Sebi's approval in August 2010 for an Rs 13,160 crore open offer for purchase of up to 20 per cent stake from the public as part of the overall deal.

As part of the deal announced in August 2010, Vedanta group agreed to acquire up to 60 per cent stake in Cairn India from its Edinburgh-based promoter Cairn Energy and public shareholders.

This included an open offer for 20 per cent stake purchase from the public at a price of Rs 355 per share, totalling Rs 13,160 crore.

The open offer, which was initially scheduled to begin on October 11 last year and close on October 30, has been stuck for a long time given the delay in Sebi clearance.

Earlier, the regulator had asked for more details on issues like open offer price and necessary clearance to the deal from the Petroleum Ministry and PSU energy giant ONGC.

Cairn India is a three-way joint venture with Cairn, domestic oil and gas major ONGC and Petronas of Malaysia.

Presently, the Edinburgh-based Cairn Energy holds a 62.37 percent stake in Cairn India.
