The Securities and Exchange Board of India (Sebi) has made changes to not-for-profit organisations’ (NPOs) registration requirements on the social stock exchange (SSE) and the minimum subscription norms for zero-coupon zero-principal instruments. The regulator has extended the registration period for NPOs to 3 years from 2 years, as per its circular dated Wednesday. This permits them to get registered on the SSE without requiring to raise capital for one additional year, subject to approval from the exchange. This has been taken into account after considering the practical challenges NPOs face with respect to statutory and regulatory approvals.
