Netted obligation
A settlement method in which all of a member's purchase and sale transactions in a security are netted into one pay-in or pay-out figure, rather than settled trade by trade.
In plain language
A busy trading member might buy a security several times and sell it several times on the same day. Settling every single one of those trades separately would move far more shares and far more money than actually needs to move.
A netted obligation avoids that. All of a member's buys and sells in a security, for a settlement, are added up into one net figure. Only that net amount has to be delivered or received.
How it works
The workbook (Chapter 6, section 6.2) sets out netted obligation as one of two methods of determining settlement obligations, the other being gross settlement (trade-for-trade).
Under netting: all purchase and sale transactions are netted to determine the obligation. A member has to deliver a security only if its sell quantity is more than its buy quantity; if buy quantity exceeds sell quantity, the member instead receives a pay-out of the security. Fund obligations are also computed on a netted basis, across all buy and sell transactions.
Netting is what multilateral netting scales up to the whole market: the clearing corporation nets not just one member's trades but the trades of every member against each other, before determining final pay-in and pay-out figures.
A worked example
A trading member, over the course of the day, executes these trades in one security:
| Trade | Buy quantity | Sell quantity |
|---|---|---|
| 1 | 2,000 | — |
| 2 | — | 800 |
| 3 | 1,500 | — |
| 4 | — | 2,200 |
Total buy quantity = 2,000 + 1,500 = 3,500. Total sell quantity = 800 + 2,200 = 3,000. Net position = 3,500 − 3,000 = 500 shares to receive.
Under a netted obligation, the member has a single pay-in obligation to receive 500 shares — nothing about the four individual trades matters for settlement once the net figure is calculated. Had the same trades been done in a security under gross (trade-for-trade) settlement instead, the member would separately deliver 3,000 shares against its sells and separately receive 3,500 shares against its buys, with no netting between the two.
Why NISM asks about it
Chapter 6 (Settlement Process, section 6.2, Determination of Settlement Obligations) introduces netted obligation as the default method, contrasted directly with gross obligations in the very next line of the workbook. Expect a question asking which of the two methods applies by default, and a small computation of net pay-in or pay-out from a list of buy and sell trades.
Common exam traps
- Netting applies separately to securities and to funds — a member can be a net receiver of shares and a net payer of funds in the same settlement.
- Netting happens per security, not across different securities. A member long in one stock and short in another does not net the two against each other.
- This is the default cash-market method. Certain transactions or securities are instead settled gross, trade for trade, with no netting at all.
- Do not confuse netted obligation (netting within one member's own trades) with multilateral netting (the clearing corporation netting trades across all members) — netted obligation is the outcome; multilateral netting is the process that produces it market-wide.

- Gross settlementA settlement method where transactions in a security are not netted: a member's security pay-in equals cumulative sell quantity and pay-out equals cumulative buy quantity, trade by trade.
- Multilateral nettingThe clearing corporation's method of collapsing every trade a clearing member did in a settlement into one net figure per security and one net funds figure, so each member either pays in or receives a pay-out.
- Pay-inThe leg of settlement in which clearing members hand over what they owe: funds into the clearing corporation through the clearing bank, and securities into its pool account through the depository.
- Pay-outThe leg of settlement in which the clearing corporation releases what members are owed: funds credited to their clearing bank accounts, and securities now credited directly to the client's demat account.
- Net obligation reportThe end-of-day report giving a trading member's net obligation, margin deposit, margin utilised, available deposit, the pay-in or pay-out required and the transaction fee payable or receivable.
- Internal shortageA shortage that arises inside a single member's book when a selling client fails to deliver shares that were netted off against a buying client's purchase, so no obligation reached the clearing corporation.
