Time stamping
The tamper-proof stamping of every mutual fund application with location code, machine identifier, serial number, date and time at the official point of acceptance — the record that decides which NAV applies.
In plain language
Cut-off timings decide whether an investor gets today's NAV or the next business day's. A rule like that is only as good as the clock behind it.
The workbook makes the link explicit: the precision in setting cut-off timing makes sense only if there is a foolproof mechanism of capturing the time at which the sale and re-purchase applications are received. That mechanism is time stamping.
Every application is stamped where it is officially received, and that stamp — not when the investor signed the form, not when a distributor collected it — is the time that counts.
How it works
Where. Mutual funds disclose their Official Points of Acceptance (OPoAs) in the SID and on their website. All transaction requests must be submitted at OPoAs, and time stamping is done there. A distributor may collect a form as a convenience, but the time it reaches the OPoA is what is relevant.
The machine. OPoAs use time-stamping machines with a tamper-proof seal. Only vendors or persons nominated by the mutual fund may open one for repair or maintenance, and every opening must be documented and reported to the trustees.
The numbering. Applications are numbered sequentially from the machine's first number to its last before a new cycle begins — daily stamping does not restart at serial 1, so a gap or repeat shows up.
What gets stamped.
| Document | Stamp |
|---|---|
| Purchase application | Location code, machine identifier, serial number, date and time — generated automatically |
| Reverse of the payment instrument | The same number |
| Investor's acknowledgement | A similar stamp |
| Re-purchase application and its acknowledgement | The same information |
| Non-financial requests (e.g. change of address) | Stamped — but only the date is pertinent, not the time |
Online. The time as per the web server receiving the instruction decides the NAV.
Platforms. MF Utilities gives distributors a single point for time-stamping of transactions.
A worked example
Assume an equity scheme with the 3.00 pm cut-off for redemptions: same-day NAV if received before cut-off, next business day NAV if after. Tuesday is a holiday in this week. Times and amounts are illustrative.
Monday, 1.45 pm. Anil hands a redemption request for 5,000 units to his distributor in a café in Lucknow.
Monday, 3.10 pm. The distributor reaches the OPoA. The machine stamps it: location code, machine identifier, serial 004218, date, 15:10.
The stamp is after cut-off, so the request gets Wednesday's NAV (Tuesday is not a business day). If Monday's NAV was Rs 48.20 and Wednesday's is Rs 47.60:
At Monday's NAV: 5,000 × 48.20 = Rs 2,41,000
At Wednesday's NAV: 5,000 × 47.60 = Rs 2,38,000
Difference = Rs 3,000
The fact that Anil handed over the form at 1.45 pm is irrelevant. Had he placed the same redemption online at 2.55 pm, the web server's time would have given him Monday's NAV.
His change-of-address form, stamped in the same queue, is judged by the date alone.
Why NISM asks about it
Chapter 9.9 (Cut-off Time and Time Stamping) teaches the two together. Expect questions on what the stamp contains (location code, machine identifier, serial number, date, time), on which time counts — receipt at the OPoA, not handover to the distributor — on the web server time for online transactions, and on the rule that for non-financial transactions only the date matters.
Common exam traps
- The OPoA time counts, not the time the distributor received the form.
- Serial numbers do not restart at 1 each day — they run from the machine's first number to its last.
- Non-financial transactions: date is pertinent, time is not.
- Online transactions use the web server's time.
- Only vendors or persons nominated by the mutual fund may open a machine, and it must be documented and reported to the trustees — not to SEBI or AMFI.
- The reverse of the cheque carries the same stamp number as the application.
