As of December 31, 2019, non-current trade accounts receivable , gross increased by ThCh$189,920,084 compared to December 31, 2018.

On November 2, 2019, the Ministry of Energy published Law No.21,185, which creates a Transitional Mechanism for the Stabilization of Electricity Prices for Customers Subject to Tariffs Regulation. Through this Law, between July 1, 2019 and December 31, 2020, the prices to be charged to regulated customers are kept at the same price levels defined for the first half of 2019 (Decree 20T/2018) and will be called the “ Stabilized Price to Regulated Client ”(PEC in Spanish).

Between January 1, 2021 and until the end of the stabilization mechanism, the prices will be the amounts established semi-annually in accordance with article 158 of the Electricity Law, but may not exceed the PEC as adjusted by the Consumer’s Price Index as of January 1, 2021 based on the same date (adjusted PEC)

The differences that occur between the billing applying the stabilization mechanism and the theoretical billing, considering the price that would have been applied in accordance with the conditions of the respective contracts with the electricity distribution companies, will generate an account receivable in favor of the electricity generation companies with a limit of US$1,350 million until 2023. All billing differences will be denominated in US dollars and will not accrue interest until December 31, 2025. The balance must be recovered no later than December 31, 2027.

The application of the aforementioned Law, causes a greater lag in the billing and collection of sales generated in our Electricity Generation segment, with the corresponding financial and accounting impact that the situation entails. For this reason, at the end of 2019, Enel Generación Chile recognized lower revenues from energy sales and a higher financial expense of ThCh$2,600,428 and ThCh$14,250,887, respectively. In addition, a profit was recorded for exchange differences of ThCh$ 3,835,024, due to the dollarization of accounts receivable pending for invoicing, and financial income of ThCh$414,292.

In the case of our Electricity Distribution segment, the financial and accounting effects are neutralized (pass-through principle). In effect, at the end of 2019, Enel Distribución Chile recognized lower sales revenues to end customers of ThCh$ 2,083,048 and the same value as lower cost of energy purchase. On the other hand, it recognized ThCh$10,241,505 as financial income for the postponement of payment to the electricity supply providers and the same amount as financial expense for the postponement of the payment to final customers, as well as positive and negative exchange differences for ThCh$2,825,769, for the dollarization of the corresponding accounts payable and receivable already mentioned.

As a result of the situations described above and after eliminating transactions between related companies, at the end of 2019, the Group reclassified non-current trade accounts receivable for ThCh$182,076,569 and suppliers for energy purchases for ThCh$53,941,373 (see Note 24). Along with this, it meant an impact on lower revenues from energy sales of ThCh $ 3,782,091 and a lower cost in energy purchases of ThCh$1,181,163, and higher revenues and financial costs of ThCh$5,225,739 and ThCh$ 19,062,333, respectively, were recognized, (see Note 34). In addition, the Group recorded a profit for net exchange differences of ThCh $ 3,835,024, for the dollarization of accounts receivable pending billing (see Trade and other current receivable, in Note 34 corresponds to financial results).

As of December 31, 2018, the accounts receivable and payable that resulted from the differences between the prices of the electricity supply contracts and the regulated prices, amounted to ThCh$48,196,306 and ThCh$6,718,177, respectively, and were presented in short term.

The concepts indicated above, both commercial and non-commercial, although they are included in the impairment loss determination model (see Note 3.g.3), do not have a greater impact at the end of December 2019, due to the nature of these items: invoices pending issuance, invoices pending expiration or invoices due within normal business ranges.

There are no significant trade and other receivables balances held by the Group that are not available for its use.

The Group does not have customers with sales representing 10% or more of its total consolidated revenues for the years ended December 31, 2019 and 2018. Refer to Note 12.1 for detailed information on amounts, terms and conditions associated with accounts receivable from related parties.

Write-offs for past due receivables

Past due receivables are written off once all collection procedures and legal proceedings have been exhausted and the debtors’ insolvency has been demonstrated. In our power generation business, this process normally takes at least one year. In our distribution business the process takes at least twenty four months. Overall, the risk of writing off our trade receivables is limited (see Notes 3.g.3 and 22.5)
