Leading authorities on marked to market loss
Mark-to-Market (MTM) losses on forward contracts and forex derivatives are allowable as a revenue deduction under Section 37(1) where a binding obligation is created against the assessee. This is provided the assessee consistently follows the same accounting method for both profits and losses.
Fluctuations in foreign exchange currency, accounted for at the end of the accounting year using a consistent accounting system, are not notional losses and are therefore deductible. The loss accrues at the time of valuation, not solely upon remittance or repayment.
Losses on foreign exchange forward contracts are not speculative if they are entered into to cover variations in foreign exchange rates impacting import/export business. Such losses are considered business losses and not notional.
Notional foreign exchange loss on unsettled forward contracts is not allowable as a deduction. The loss is allowable only upon settlement of the contract.
Mark-to-market losses are allowable as deductions. The disallowance of such losses by the Assessing Officer is deleted.
