The Indian government is considering an initial public offer for state-owned telecom major Bharat Sanchar Nigam Ltd, the company said on Monday.

The public issue is likely to help raise Rs 15,000-20,000 crore (Rs 150-200 billion).

According to S D Saxena, BSNL director (finance), the telecom giant's value has been estimated at $100 billion. BSNL may dilute about 10 per cent stake through the IPO.

The IPO exercise is likely to begin in 2-3 months and will be completed within a year, Saxena said.
