 uncertainty. The most probable amount
method provides as an estimate the single most probable amount in a set of possible outcomes, while the expected amount method represents

| 4.10. | Sources of estimation uncertainty 
 related to expected credit losses |

Credit losses correspond to the difference between
all contractual cash flows owed to the Company and all cash flows that the entity expects to receive, discounted at the original effective
interest rate. The expected credit loss of a financial asset corresponds to the average of expected credit losses weighted by the respective
default risks.

Expected credit losses on financial assets are
based on assumptions relating to risk of default, the determination of whether or not there has been a significant increase in credit
risk, expectation of recovery, among others. The Company uses judgment for such assumptions in addition to information from credit rating
agencies and inputs based on collection delays.

Notes 14.2 and 14.3 provide details on the expected
credit losses recognized by the Company.

Surplus Volume of the Transfer of Rights Agreement under the Production Sharing regime, the Company signed amendments and new agreements

upon signature, possible additional amounts receivable that may be owed to the Company, according to the conditions described in note
29.3.

Additionally, over the last few years the Company
has sold assets considered non-strategic and established partnerships in E&P assets aiming, among other objectives, at sharing risks
and developing new technologies. Such transactions were carried out through partnerships (note 27) and divestments, with procedures aligned

clauses (note 29.3).
