(14) Impairment of non-monetary assets
Intangible assets with indefinite useful lives such as goodwill and membership, or intangible assets that are not yet available for use are tested for impairment annually, regardless of whether or not there is any indication of impairment. All other assets are tested for impairment when there is an objective indication that the carrying amount may not be recoverable, and if the indication exists. The Group estimates the recoverable amount. Recoverable amount is the higher of value in use and net fair value less costs to sell. If the recoverable amount of an asset is estimated to be less than its carrying amount, the carrying amount of the asset is reduced to its recoverable amount and such impairment loss is recognized immediately in net income.
