Self-business

A mutual fund distributor earns trail commission for bringing an investor's money into a scheme. The workbook makes one thing explicit: that reward is for mobilising someone else's money. When a distributor invests their own money in a scheme they are empanelled to sell, that investment is called self-business, and no commission is payable on it.

The logic follows directly from how trail commission is calculated. Trail commission for a day is:

Trail commission for the day = AUM × trail commission rate p.a. ÷ 365

That formula is paid to compensate the distributor for the work of finding and servicing an investor. A distributor's own units sit in the scheme's AUM like anyone else's, but since there is no investor being served — the distributor is the investor — the AMC excludes that block of units from the AUM on which commission is calculated. The units still earn the scheme's returns; they simply earn no trail commission on top.

Mr Deshmukh is an empanelled mutual fund distributor earning a 1% p.a. trail commission on the business he mobilises. He recommends a scheme to a client, who invests Rs 10 lakh — Mr Deshmukh earns roughly Rs 10,000 a year in trail commission on that block (10,00,000 × 1% ÷ 365, compounded daily as the NAV moves, per the same formula the AMC uses for every other distributor).

Mr Deshmukh separately invests Rs 10 lakh of his own savings in the very same scheme, through his own ARN as the distributor of record. On this second Rs 10 lakh he earns no trail commission at all — it is self-business. His personal investment still grows or falls with the scheme's NAV exactly like the client's does; only the commission is switched off.

Chapter 6, section 6.5.1 (Concept of Trail Commission), in the single line that follows the worked trail-commission table: commission exists to mobilise money from clients, so no commission is payable to the distributor for their own investments (self-business). Expect a direct one-line recall question built on exactly this sentence.

• Self-business still earns scheme returns. What is switched off is commission, not the investment itself.
• It applies to the distributor's own money, not to money they mobilise from family or clients under a different arrangement — routing a client's money through one's own folio to inflate personal AUM does not turn it into self-business, and raises its own compliance questions.
• Do not confuse this with upfront commission, which has been withdrawn industry-wide for a separate reason (SEBI's move to a full trail model); self-business is excluded from trail commission specifically because there is no client being served.
