Answer:
This first statement it's to record an estimation of uncollectible accounts
Explanation:
When the company determined the percentage of total amount of accounts receivables as uncollectible, the journal entry required is Bad Expenses (debit) with Allowance for Uncollectible Accounts (credit)
At the moment of the write-off as the expenses were before recognized we only use the Allowance for Uncollectible Accounts (Debit) with Accounts Receivable (Credit), with this we are recognizing the uncollectible credit of the company.
The other way it's to write-off directly the bad debts at the moment decided that the credit are uncollectible, the total amount it's reported as bad debt expenses which affect negativly the income statement and the accounts receivable are reduce in the same amount, less assets.
