Investments made by AIFs have crossed the Rs 24,800-crore mark at the end of the second quarter of 2016-17, a jump of 20 per cent from the preceding three months. Year-on-year, the AIF investment has more than doubled from Rs 11,254.71 crore at the end of September last year. Alternative Investment Funds are a class of pooled-in vehicles for investing in real estate, private equity and hedge funds. The investment by AIFs stood at Rs 24,862.19 crore as of September 30 compared to Rs 20,667.2 crore at the end of June 30, according to the latest data with the Securities and Exchange Board of India (Sebi). The Category I AIFs poured in Rs 3,517 crore, Category II Rs 15,334 crore and Category III Rs 6,010 crore. The regulator, in May 2012, notified the guidelines for this class of market intermediaries. At the end of December 2012, they pumped in just Rs 20 lakh, which has now jumped to more than Rs 24,000 crore. AIFs are funds set up or incorporated in India for the purpose of pooling in capital from Indian and foreign investors for investment as per a pre-decided policy. Under Sebi guidelines, AIFs can operate broadly in three categories. The Category-I AIFs are those funds that get incentives from the government, Sebi or other regulators and include social venture, infrastructure, venture capital and SME funds.
