Impairment
Impairment occurs when the carrying value of an asset on the balance sheet exceeds its recoverable amount — the higher of its fair value less costs to sell and its value in use — requiring the company to write down the asset value and recognise an impairment loss in the income statement.
Impairment was a fundamental principle of Ind AS and IFRS-based accounting: assets must not be carried at values in excess of what they could generate or be sold for. Ind AS 36 (Impairment of Assets) provided the framework for testing non-financial assets — including property, plant and equipment, goodwill, intangible assets, and investments in subsidiaries and associates — for impairment. Financial assets were tested under Ind AS 109 using the Expected Credit Loss model.
The mechanics of impairment testing involved estimating the recoverable amount, defined as the higher of: (a) Fair Value Less Costs of Disposal (what the asset could be sold for in an arm's-length transaction) and (b) Value in Use (the present value of future cash flows expected from continuing to use the asset in the business). If the carrying amount exceeded this recoverable amount, the excess was recognised as an impairment loss, reducing both the asset value on the balance sheet and the period's profit on the income statement.
Goodwill, arising from acquisitions, was subject to mandatory annual impairment testing under Ind AS 36 rather than scheduled amortisation. This made goodwill impairment charges a highly scrutinised area in Indian corporate reporting. Several notable impairment charges appeared in Indian financial history: Tata Steel's impairment of its European operations, Bharti Airtel's recognition of goodwill impairments on overseas African acquisitions, and various IT services companies impairing investments in acquired entities that failed to perform as expected. Each such impairment represented a formal acknowledgement that a prior acquisition had not delivered anticipated value.
For analysts, impairment charges were informative on multiple levels. First, they signalled strategic missteps — an acquisition that required impairment had been made at too high a price or had underperformed operationally. Second, because impairment tests required discounted cash flow projections by management, the assumptions disclosed in the notes — discount rates used, terminal growth rates, projected revenue growth — provided a window into management's own internal view of an asset's value. Third, recurring impairments by the same management team raised governance questions about capital allocation discipline.
The distinction between impairment and depreciation was important: depreciation was a systematic, scheduled reduction of asset value over useful life (non-event-driven), while impairment was a one-off write-down triggered by a specific adverse development. Both reduced asset carrying value and hit the income statement, but impairment was usually a signal of something having gone wrong, while depreciation was a normal course of business allocation.
