The government will only monetise under-utilised assets and the ownership will remain with the centre, the finance minister Nirmala Sitharaman said while unveiling the Rs 6 lakh crore National Monetisation Pipeline. "National Monetisation Pipeline talks about brownfield assets where investment is already being made, where there are assets either languishing or not fully monetised or under-utilised, Nirmala Sitharaman emphasised. The brownfield assets will be monetisatised by bringing in private participation.
