New Delhi: Public sector carrier Bharat Sanchar Nigam Limited BSNL ) is expected to post losses of over Rs 14,000 crore for the financial year 2018-19, while its revenue is slated to be around Rs 19,308 crore.Salary expenditure is set to be a massive 75% of the firm's total revenue at Rs 14,488 crore, telecom and IT minister Ravi Shankar Prasad said in a written reply to the Lok Sabha Wednesday.The public sector firm's provisional loss was Rs 4,859 crore in 2015-16, Rs 4,793 crore in 2016-17, Rs 7,993 crore in 2017-18 and is estimated to balloon to Rs 14,202 crore in 2018-19.“Low tariffs due to fierce competition in the mobile segment, high staff cost and absence of 4G services (except in few places) in the data-centric telecom market are the main reasons for losses of BSNL,” Prasad said.In line with the sector, BSNL has also seen a dip in its revenue after the entry of Reliance Jio in the market in 2016.The company's revenue is pegged at around Rs 19,308 crore for 2018-19, compared with Rs 25,071 crore in 2017-18 and Rs 31,533 crore in 2016-17.The numbers reflect the tough financial situation of BSNL, one of the public carriers for which the government is planning a revival scheme. Prasad said recently that a cabinet note on the revival package to be offered to BSNL and Mahanagar Telecommunications Nigam Ltd ( MTNL ) would be sent for approval, which will be aimed at making them more competitive and professional through rehabilitation.“They’re a national asset, they operate in strategic regions such, and in case of need like in natural disasters, they're in forefront of giving free services,” Prasad had said.The minister had told the Parliament last week that absence of 4G services and high employee costs were dragging the state-run carriers. Request for additional spectrum with government support for providing 4G services is also included in the revival plan, which was being prepared IIM Ahemdabad and Deloitte.
