Infrastructure Investment Trust (InvIT) is an instrument on the pattern of mutual funds, designed to pool money from investors and invest in assets that will provide cash flows over a period of time. Elaborating further, the official told PTI that while Rs 15,000 crore is planned to be raised in 2023-24 via project-based financing of high-speed corridors by securitising the future toll revenues without any guidance from the authority, Rs 10,000 is planned to be raised via InvIT.
