Enough liquidity in system, not enough confidence, says Piramal. : Mumbai/Bengaluru: Piramal Group flagship Piramal Enterprises Ltd (PEL) is open to tying up with private equity funds to acquire select non-banking financial company (NBFC) portfolios, group chairman Ajay Piramal said. “There are many PE funds who think this is an opportunity to acquire portfolios and assets which are at reasonable valuations. We have looked at some proposals and if there is enough substance, then I think there are enough people who would be ready to partner with us,” Piramal said in an interview.
