Intangible assets include assets acquired by the Company and its subsidiaries from third parties, according to the criteria below (see Note 13):
| • | Goodwill is carried net of accumulated amortization as of December 31, 2008, when it ceased to be amortized. Goodwill generated since January 1, 2009 is shown as intangible assets corresponding to the positive difference between the amount paid or payable to the seller and the fair value of the identified assets and liabilities assumed of the acquired entity. Goodwill is tested annually for impairment. Goodwill is allocated to the business segments, which represent the lowest level that goodwill is monitored by the Company for impairment testing purposes (see Note 13.i). | |
| • | Exclusive rights disbursements as provided in Ipiranga’s agreements with reseller service stations and major consumers are recognized as distribution rights when paid and amortized according to the conditions established in the agreements (see Note 13.v). | |
| • | Other intangible assets acquired from third parties, such as software, technology, and commercial property rights, are measured at the total acquisition cost and amortized using straight-line method, over the periods mentioned in Note 13, taking into account their useful life, which is reviewed annually. |
The Company and its subsidiaries have not recognized intangible assets that were generated internally. The Company and its subsidiaries have goodwill and brands acquired in business combinations, which are evaluated as intangible assets with indefinite useful life (see Note 13 items i and vi).
