NIIF was set up in 2015 as an investment vehicle for funding commercially viable greenfield, brownfield and stalled projects in the infrastructure sector. NIIF will invest in areas such as energy, transportation, housing, water, waste management and other infrastructure-related sectors in India. The corpus of the fund is proposed to be around Rs 40,000 crore, with the government investing 49% and the rest to be raised from third- party investors such as sovereign wealth funds, insurance and pension funds, endowments etc. Recently, the National Investment and Infrastructure Fund (NIIF) of India has signed an investment agreement worth $1 billion with a wholly owned unit of the Abu Dhabi Investment Authority (ADIA).
