Accounts receivable from customers, traders and power transport concession holders are initially recognized at the sales value of the energy supplied or the value of the gas supplied and are measured at amortized cost. These receivables are stated with the amount of sales tax included, net of the taxes withheld by the payers, which are recognized as recoverable taxes.

The contract asset is transferred to the financial asset (Consumers and resellers and concessionaires - Energy transport), within the scope of IFRS 9, after the issuance of the credit notice, monthly issued by ONS, authorizing RAP billing, which is when the right to consideration is unconditional.

The financial asset is recognized at the transaction price and the assets are subsequently measured at amortized cost, using the effective interest method, adjusted by impairment losses, when applicable, and recognizing the deferred taxes. As required by IFRS 9 - Financial Instruments, the financial asset carrying amount is analyzed and, when applicable, a loss allowance for expected credit losses is recognized.

The adjustment for expected credit losses is recorded based on policies approved by Management. The main criteria defined by the Company and its subsidiaries are: (i) for consumers with significant amounts outstanding, the balance receivable is analyzed taking into account the history of the debt, ongoing negotiations and real guarantees; and (ii) for large consumers, an individual analysis is made of debtors and ongoing initiatives to receive the credits.

For captive customers, the Company adopts in its analysis a simplified approach, considering that the balances of its Accounts Receivable do not have significant financing components and estimates the expected loss considering the average history of non-collection over the total amount billed in each month, based on 24 months of billing, segregated by consumer class and projected for the next 12 months considering the age of maturity of the invoices, including those not yet due and unbilled.

The Company has adopted a differentiated rule for the amounts to be received from billing of irregular debits, due to their representing greater difficulty in collection. The analysis is individualized; a level of solvency for the client is calculated internally, and weighted in the measurement of the risk of loss.

The expected losses for overdue accounts of customers that renegotiated their debt is measured based on the maturity date of the original invoice, despite the new terms negotiated. Expected losses are fully recognized for accounts overdue for more than 24 months.

Expected losses for invoices unbilled, not yet due or less than 12 months past due are measured according to the potential default events, or losses of credit expected for the whole life of a financial instrument, if the credit risk has significantly increased since its initial recognition.
