Mr Gopal, AS 9 does not deal with the situation of SWAP/Barter.IFRS-18 deals with this kind of a transaction. Swap is nothing but exchange of goods for goods.
As per IFRS 18 a transaction is not regarded as generating revenue if goods/services are exchanged for goods/services of a similar nature and value.
When goods/services are supplied/ rendered in exchange for dissimilar goods/services, the exchange is regarded as a transaction which generates revenue.
In such circumstances the revenue is measured at FV of G/s rendered/receivable, adjusted by the amt of any cash/C.E. t/fd
Where FV of G/S recd.cannot be measured reliably, the FV is measured by reference to the FV of G/S provided.
