Goodwill acquired related to the acquisition of subsidiaries is included in the line-item goodwill, which is subject to impairment tests annually or more frequently if events or changes in circumstances indicate that it might be impaired and is stated at cost less accumulated impairment losses. Gains and losses related to the sale of an entity include the carrying value of goodwill related to the entity sold. This intangible asset is assigned to cash-generating units with the purpose of testing impairment losses. It is allocated based on cash-generating units expected to obtain benefits from the business combination from which the aforementioned goodwill acquired arose. 3.21 Intangible assets other than goodwill Intangible assets other than goodwill mainly relate to water rights, costs for rights of way for electricity lines, software and licensing costs, the development of computer software and mining property and concession rights. (a) Water rights Water rights acquired by the Company relate to water from natural sources and are recorded at acquisition cost. The Company separates water rights into: i) Finite rights with amortization using the straight-line method, and ii) Indefinite rights, which are not amortized, given that these assets represent rights granted in perpetuity to the Company and subject to an annual impairment assessment. (b) Rights of way for electric lines As required for the operation of industrial plants, the Company has paid rights of way to install wires for the different electric lines on third party land.
