What is the value of the estimated loss with doubtful accounts (PECLD) in the company's accounts receivable in 2019?

The estimated loss with doubtful accounts (PECLD) is considered sufficient to cover any losses on outstanding receivables.
The balance of the estimated loss with doubtful accounts corresponds substantially to invoices with a high risk of non-receipt.
The company constantly monitors the balance of receivables and its estimates of default, considering the concept of incurred loss and expected loss.
