Trade receivables due from customers are recognized net of loss allowances, which totaled €3,287 million at the end of the year, compared with a balance of €2,980 million at the end of the previous year. Specifically, the reduction for the year, totaling €1,037 million, mainly recognized in Italy (€819 million) and Latin America (€176 million), was attributable to the decline in receivables for the sale and transport of electricity and gas, the deterioration in the collection status of certain receivables and an increase in write-downs, all connected with the effects of the COVID-19 pandemic, as well as the depreciation of the Latin American currencies.
