Anil Ambani Group firm, which was previously in talks with Bahrain Telecommunications Co (Batelco) for selling a stake in Reliance Globalcom Ltd, hopes to conclude a deal with the consortium of PE funds by May-end, Reliance Communications (RCom) had said last week.

The consortium, which also includes Providence and Carlyle, may buy up to 80 per cent in Reliance Globalcom which also owns the group's undersea cable business, for USD 1-1.2 billion, industry sources had said.

The stake sale is expected to be used by RCom to lower its debt burden which stood at around Rs 37,000 crore as on December 31, 2012.

"Samena Capital, in a proposed consortium with certain other global PE funds, is at an advanced stage of the process of due diligence and completion of definitive documents in relation to the acquisition of Reliance Globalcom Ltd," RCom said in a filing to the stock exchanges.
