All of the following are key similarities between GAAP and IFRS with respect to accounting for intangible assets except:

(a) for accounting purposes, costs associated with research and development activities are segregated into the two components.

(b) the accounting for intangibles acquired in a business combination.

(c) recovery of impairments on intangibles other than goodwill.

(d) the accounting for impairments of assets held for disposal.

IFRS refers to a collection of globally agreed accounting and financial reporting rules for preparing and presenting financial statements. Ensures that accounting practices are consistent, resulting in comparable financial records among various reporting substances worldwide.

For long-lived assets and intangibles, IFRS orders an impairment test at each reporting date and the recording of impairment. Suppose an asset's carrying sum is more than its recoverable amount. In that case, the recoverable sum will be more noteworthy than the whole of the asset's reasonable value, cost to sell, and value in utilization. Value in use is the present value marked down to the longer-term cash stream created by the particular assets. With GAAP, the excess carrying amount over the asset’s fair value is the impairment loss.

When there has been a change in the economic environment or the anticipated use of the asset, IFRS permits the reversal of impairment losses for limited life intangibles. According to GAAP, impairment losses for assets still being kept and used result in a new cost basis for the support and cannot be changed.

So, the correct option is (c) recovery of impairments on intangibles other than goodwill.

Option a) Writing down all research costs to the profit and loss account as caused is the bookkeeping method for them. As a general rule, like with investigation costs, development costs should be recorded as they are caused within the profit and loss account.

Option b) The income strategy (ASC 820-10-55-3F), which changes future amounts to be earned from the resource to a single current or present value employing a discount rate, is the foremost frequently utilized strategy for valuing intangible assets in a business combination.

Option d) A loss or pick up is balanced for an impairment loss (or in comprehensive income if it may be a revaluation diminish under IAS 16 or IAS 38). Reduced is the asset's (or cash-generating unit's) carrying sum. In a cash-generating unit, goodwill is devalued, to begin with, followed by other resources, pro rata.
