The Finance Ministry is hopeful of raising Rs 12,000-13,000 crore from stake sale in the public sector undertakings (PSUs) by December-end which could help the government to rein in fiscal deficit to around 5.3 per cent of the GDP in 2012-13.Talking to reporters in New Delhi on Thursday, Department of Economic Affairs (DEA) Secretary Arvind Mayaram expressed hope that disinvestment will pick up and Rs 30,000 crore may be raised for the full fiscal.Ruling out any further borrowing by the government, Mayaram said government is aiming to bring the fiscal deficit down to 3 per cent by 2016-17. He said, the deficit will be controlled by reducing expenditure and realising funds from PSU disinvestment.Although the government had pegged fiscal deficit for the current financial year at 5.1 per cent in the budget, it will not be able to achieve the target in view of rising subsidy bill and lower buoyancy in tax collection.Finance Ministry officials are engaging in hectic parleys with the PSUs to speed up the process so that the disinvestments can take place in the December and March quarters.The Department of Disinvestment (DoD), the modal department for conducting PSU stake sale, has already secured Cabinet approval for stake sale in four companies — Oil India, MMTC, Hindustan Copper and Nalco– which could fetch about Rs. 15,000 crore to the exchequer.
