Jumbo lot
A single certificate covering an entire rematerialisation request, one of two delivery options a client can choose on the RRF — the other being separate certificates in ordinary market lots.
In plain language
An investor rematerialises securities. The Issuer or R&T Agent must then issue physical certificates back. These certificates can be printed in different sizes, and the investor picks which.
One choice is a jumbo lot. This is a single certificate for the entire quantity requested. The other choice is market lot — separate certificates in the market's usual tradable size. The client marks this choice on the Rematerialisation Request Form itself.
How it works
From Chapter 7, section 7.4.2, on the checks a DP makes when validating an RRF: among the points to verify is "the client's option whether to receive the physical certificates either in jumbo lot for the entire quantity requested or in market lot."
This sits alongside the RRF's other completeness checks: sufficient free/lock-in balance to honour the request, matching name and order of joint holders, and separate RRFs required for free and locked-in securities, for securities locked in for different reasons, for each ISIN, and for securities of different paid-up value. Under the tripartite agreement, rematerialisation requests are generally processed within 30 days.
A worked example
Mr Kadam submits an RRF to rematerialise 2,000 shares he holds electronically. On the form he ticks the jumbo lot option.
| Option | What Mr Kadam receives |
|---|---|
| Jumbo lot | One certificate for all 2,000 shares |
| Market lot | Multiple certificates, each in the standard market denomination (e.g. lots of 100) |
Because he chose jumbo lot, the Issuer's R&T Agent issues him a single certificate for 2,000 shares rather than twenty certificates of 100 shares each — simpler to hold, but if he ever wants to sell only part of the holding in physical form again, he would first need the certificate split or re-dematerialised.
Why NISM asks about it
Chapter 7, section 7.4.2, lists jumbo-lot-versus-market-lot as one of the specific fields a DP must check for completeness on an RRF. Expect it tested as a straight definitional recall alongside the other RRF completeness checks.
Common exam traps
- Jumbo lot is a client choice made on the RRF itself, not something the Issuer/R&T Agent decides unilaterally.
- It applies to rematerialisation, not dematerialisation — there is no equivalent choice when securities go into the depository.
- Do not confuse jumbo lot with odd lot: an odd lot is a sub-standard physical holding from the pre-depository era; a jumbo lot is a single oversized certificate an investor can deliberately request today.
Where this is taught
Free preparation for NISM Series VIRelated terms
- RematerialisationThe reverse of dematerialisation — the demat account is debited and the issuer prints fresh physical certificates for the same quantity, to be despatched within 30 days.
- FungibilityIn the depository, securities of the same class carry no distinctive or certificate numbers — every unit is identical to every other and interchangeable, so title is counted in numbers, not in serial numbers.
- ISINThe 12-character code (ISO 6166) that identifies one specific security in the depository system — country prefix, nine-character basic number and a check digit, as in INE475C01012.
- Temporary illiquidityThe workbook's name for the period a rematerialisation request makes securities untradeable — starting the moment the DP accepts the request, not the moment the account is actually debited.
