The document outlines new regulations from the Securities and Exchange Board of India regarding investment restrictions for mutual funds. It reduces the limit of investments in debt instruments issued by a single issuer from 30% to 25% of a fund's net assets. It also introduces a limit of 20% of net assets for total exposure to a single group, and allows up to 25% with trustee approval. Additionally, mutual funds must ensure their exposure across sectors does not exceed 25% of net assets. Existing funds have one year to comply with the new rules.
