The Three-Tier Structure
1. Sponsor
The entity that sets up the mutual fund. Must have a sound track record (at least 5 years in financial services), positive net worth, and minimum 40% contribution to AMC's net worth. Examples: SBI (for SBI MF), HDFC Bank/Standard Life (for HDFC AMC).
2. Trust and Trustees
The mutual fund is constituted as a Trust under the Indian Trusts Act, 1882. The Board of Trustees (or a Trustee Company) holds the fund's assets in trust for unitholders. At least 2/3 of trustees must be independent (not associated with the sponsor).
Trustees are legally responsible for ensuring the AMC operates in compliance with SEBI regulations and in the best interests of unitholders. They can remove the AMC with SEBI approval.
3. Asset Management Company (AMC)
The AMC actually manages the investments. SEBI requires:
- Minimum net worth: ₹50 crore at all times
- SEBI registration and approval
- Separate custodian (cannot self-custody)
- Independent compliance officer and risk management systems
Supporting Entities
Custodian
Holds the physical/demat securities on behalf of the fund. Must be SEBI-registered. The custodian confirms trade settlements and maintains the fund's portfolio in safe custody.
RTA (Registrar and Transfer Agent)
Manages all investor-level transactions — unit allotment, redemption, SIP processing, folio statements. Major RTAs in India: CAMS (Computer Age Management Services) and KFintech (formerly Karvy Computershare).
