Accounting policy Accounts receivable from consumers, 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 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. As required by IFRS 9, the financial asset carrying amount is analyzed and, when applicable, a loss allowance for expected credit losses is recognized. In the transmission activity, the Permitted Annual Revenue (Receita Anual Permitida, or ‘RAP’) remunerates the investment in transmission lines, services of enhancement and improvement, and operation and maintenance. Revenues from the concession contracts are recognized as and when the corresponding performance obligations are satisfied, with a counterpart in Contractual assets. The contractual asset is reclassified as a financial asset (Concession holders – power transport) only after satisfaction of the performance obligation to operate and maintain infrastructure, since after that point nothing more than the passage of time is necessary for the consideration to be received. Estimations and judgments Expected Credit Losses (ECL) 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 consumers, Cemig D 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 36 months of billing, 36 months for consumer with regular consumption; and 18 months for consumer with irregular consumption, 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 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 36 months. A different rule is adopted for amounts of billing receivable from consumers with an irregular of debits, since by nature they are more difficult to collect. The analysis is individualized: a level of solvency for the consumer is calculated internally, and weighted in the measurement of the risk of loss. 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. For debits owed by consumer with irregular billing, because of the differentiated nature of their collection, analysis is individualized and the level of solvency, calculated internally for the consumer, is weighted in the management of the risk of losses. When estimating ECL and recognizing write-off of default, in the case of large consumers, the study is of a nature requiring judgment (individualized analysis), and takes into account: the history of the debt, any existing guarantees, initiatives that are in progress for receipt of the receivables, and in some cases, assessment by credit reference bureaus. For Cemig GT and Cemig, the balance receivable is analyzed in its totality, taking into account the history of the debt, the negotiations in progress and any asset guarantees; and individual analysis is made of the debtors and of the initiatives in progress for receipt of the amounts owed. Note that no expected credit loss is made in relation to contracts with traders, since the energy traded is delivered only after payment in advance, or provision of guarantees. Gasmig also uses individualized analysis to estimate levels of expected credit losses for large consumers, considering debt history, existing guarantees and ongoing initiatives to receive credits.
