Trade receivables from customers are recognized net of allowances for doubtful accounts, which totaled €2,980 million at the end of the year, compare with a balance of €2,828 million at the end of the previous year. Specifically, the reduction for the period was mainly due to a decline in receivables for the sale and transport of electricity, to an increase in writedowns and to ordinary developments in receivables.
