Jayant Patil, a member of the executive committee of management at Larsen & Toubro (L&T), and advisor (defence and smart technologies) to the L&T chairman and managing director, said: "The government has taken steps to create a level playing field between private firms and DPSUs. However, major acquisitions continue through nominations, ignoring competitive bidding and the level playing field." This makes it difficult for private companies to secure contracts, he said, adding: "Curbing nominations would be a significant step forward. More contracts for private firms, whose share in indigenous acquisition has stagnated at 20 per cent, would mean greater funds at their disposal to invest in research and development."
