| 2.8. | Losses for impairment of non-financial assets |
Intangible assets that have an indefinite useful life, and developing IT projects, are not subject to amortization and are subject to annual testing for impairment. Assets subject to amortization are subjected to impairment tests whenever any event or change in circumstances indicates that the book value of the assets may not be recoverable. An impairment loss is recorded when the book value is greater than the recoverable amount. The recoverable amount of an asset is the higher of its fair value less costs to sell and its value in use. In evaluating the impairment, the assets are grouped at the lowest level for which cash flows are separately identifiable (CGUs). Non-financial assets other than goodwill that have suffered an impairment loss are reviewed if there are indicators of reverse losses at each reporting date.
