The Company tests annually its assets for impairment or when there is an indication that their carrying amount may not be recoverable. In the six-month period ended June 30, 2023, the Company recognized net impairment losses amounting to US$ 404, mainly arising from the assessment of the second refining unit of RNEST, which resulted in the recognition of a US$ 383 loss, mainly due to: (i) review of the scope for the implementation of logistics infrastructure, with an increase in necessary investments; (ii) increase in the discount rate to 7.4% p.a. (from 7.1% p.a. in December 2022); and (iii) appreciation of the real against the dollar on estimated future cash flows. In the six-month period ended June 30, 2022, the Company recognized net impairment losses amounting to US$ 167, mainly due to:
| · | definitive cessation of the operations of platform P-35, in the Marlim field, which led to the exclusion of this asset from the CGU North group and classification as a separate asset, resulting in the recognition of a US$ 52 impairment loss;
| · | approval for the disposal of Golfinho group of fields, which comprises Golfinho field (which produces oil), Canapu field (which produces non-associated gas), and the exploratory block BM-ES-23. As a result, the Company assessed the recoverability of the carrying amount of these assets, considering the fair value net of disposal expenses, resulting in the recognition of a US$ 51 impairment loss;
| · | approval for the disposal of LUBNOR Refinery, in the state of Ceará, separating it from the Downstream CGU. As a result, the Company assessed the recoverability of the carrying amount of the refinery, considering the fair value net of disposal expenses, resulting in the recognition of a US$ 44 impairment loss.
