(l)Impairment of Long-lived Assets
The Group reviews for impairment the carrying amounts of its long-lived assets, tangible and intangible, including goodwill (see Note 12), at least once a year, or whenever events or changes in business circumstances indicate that these carrying amounts may not be recoverable. An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs to sell and value in use. To determine whether an impairment exists, the carrying value of the reporting unit is compared with its recoverable amount. Fair value estimates are based on quoted market values in active markets, if available. If quoted market prices are not available, the estimate of fair value is based on various valuation techniques, including discounted value of estimated future cash flows, market multiples or third-party appraisal valuations.
