Thank you for the reply. However, our scenario as follows:-
Company A, SGD book currency, purchase vessel USD1,000,000, book as exchange rate 1.383, SGD1,383,000.
However, we decided to sell the vessel as USD1,000,000 to Company B, USD book currency. during that time, the exchange rate is 1.354.
So shall the diff of SGD29,000 (SGD1,383,000 - SGD1,354,000) be recognized under Company A or shall it be include in the billing to Company B (USD1,000,000 + SGD29,000).
