Fair valuation losses on principal protected debentures recognised on accrual basis are deductible under general deduction principles.

Unrealized fair valuation loss on principal protected benchmark linked debentures recognised on an accrual (mercantile) basis is treated as an allowable expenditure under the general deduction principle where the contractual obligation to pay principal exists at the balance sheet date; the uncertainty relates only to the quantum contingent on future index performance. The analysis applies mark to market valuation and principles of crystallization of liability and prudent accounting, permitting recognition of estimable losses and later reversal if valuations change, thereby distinguishing such losses from purely contingent liabilities.

Issues: Whether the unrealized loss on fair valuation of principal-protected benchmark linked debentures (BLDs) as on the balance sheet date is an allowable expenditure under Section 37(1) of the Income-tax Act, 1961 or is a contingent liability not allowable for the assessment year 2012-13.

Analysis: The issue was examined in the context of the assessee following the mercantile (accrual) basis of accounting under Section 145 of the Income-tax Act, 1961 and applying accepted accounting principles to mark-to-market valuation of BLDs. The obligations arising from legally binding BLD contracts existed on the balance sheet date; only the quantum of payment contingent on future index performance (a trigger set at 120% of the start level) remained uncertain. Established principles on crystallization of liability and prudent accounting require recognition of liabilities and anticipated losses that have arisen and are estimable with reasonable certainty. The approach of recognizing fair valuation losses (and reversing them if subsequent movements so require) aligns with mercantile accounting and recognised judicial authorities applying Section 37(1) to similar mark-to-market losses where the underlying obligation has arisen. The contingent nature argued by Revenue was distinguished because the contractual obligation to pay principal exists and the fair valuation loss on the balance sheet date reflects an accrued expenditure whose quantification may vary but which is not purely contingent on a future event.

Conclusion: The unrealized fair valuation loss on the principal-protected BLDs as on the balance sheet date is allowable as expenditure under Section 37(1) of the Income-tax Act, 1961; the disallowance by the Assessing Officer is deleted and the assessee's ground is allowed.
