Composite commodity derivative business allows aggregation of profits and losses across exchanges, including unnotified exchange transactions.

Commodity derivative trading carried on only as one line of business across multiple exchanges constituted a single composite business for tax purposes, so profits and losses from the different exchanges had to be aggregated for set-off. The legal character of the transactions depended on the nature of the activity, not on the exchange through which they were executed, and the business could not be split merely because trades were routed through different exchanges. Loss from transactions on an exchange not separately notified by CBDT was also treated as part of the same species of commodity derivative business, so it could be set off against profit from a recognised exchange.

Issues: (i) Whether commodity derivative trading carried on through multiple exchanges constituted one composite business for tax purposes so that profits and losses from different exchanges could be aggregated and set off against each other. (ii) Whether loss from commodity derivative trading on an exchange not notified by the Central Board of Direct Taxes could be treated as speculative loss and denied set-off against profit from another recognised exchange.

Issue (i): Whether commodity derivative trading carried on through multiple exchanges constituted one composite business for tax purposes so that profits and losses from different exchanges could be aggregated and set off against each other.

Analysis: The assessee was engaged only in commodity derivative trading, and the activity was carried on across different commodity exchanges as part of the same line of business. The legal character of the transactions depended on the nature of the activity and not merely on the exchange through which they were routed. The business, therefore, could not be split into separate trades merely because transactions were executed on different exchanges.

Conclusion: The business was a single composite business, and the resulting profits and losses were required to be aggregated for set-off purposes.

Issue (ii): Whether loss from commodity derivative trading on an exchange not notified by the Central Board of Direct Taxes could be treated as speculative loss and denied set-off against profit from another recognised exchange.

Analysis: Before the amendment introducing clause (e) to the proviso to section 43(5), commodity derivative transactions were treated as speculative transactions, and the amendment did not justify treating the same business differently merely because one exchange was not separately notified by the Central Board of Direct Taxes, when both exchanges were recognised associations under the governing commodity law. The assessee's loss on one exchange and profit on another arose from the same species of transactions and fell to be considered together.

Conclusion: The loss on the unnotified exchange was allowable to be set off against the profit on the recognised exchange.

Final Conclusion: The additions made by the lower authorities were unsustainable, and the assessee's commodity derivative loss was directed to be allowed against the corresponding commodity derivative profit while the Revenue's challenge to that treatment failed.

Ratio Decidendi: Where an assessee carries on only commodity derivative trading as one composite business, profits and losses from different exchanges must be aggregated, and the set-off cannot be denied merely because one exchange is not separately notified when the transactions are of the same nature.
