As per the Securities Laws (Amendment), Act 2014 when a corpus amount of Rs 100 crore or more is sourced from investors is called Collective Investment Scheme (CIS). It is compulsory for every CIS to register with SEBI and obtain a credit rating from a verified rating agency. The credit rating of these schemes implies whether the scheme will be successful or not. The rating is awarded as per an approved rating scale, where CS1 is the highest grade and CS 5 is the high risk grade.
