RCom is looking at listing Flag Telecom through a Singapore business trust, Global Telecommunications Infrastructure Trust on the Singapore stock exchange.
The Monetary Authority of Singapore is Singapore's central bank and financial regulatory authority.
"The business trust, GTIT, has lodged a copy of the preliminary prospectus with the Monetary Authority of Singapore," RCom said in a statement on Thursday.
On June 12, 2012, the Singapore Exchange Securities Trading Ltd had granted an 'eligibility to list' to GTIT, subject to requisite conditions being satisfied.
The IPO is expected to raise about Rs 5,000-6,000 crore (Rs 50-60 billion)
