At the start of the year, Winston Company’s Allowance for Doubtful Accounts had a credit balance of $14,000. During the year, it had credit sales of $1,500,000. It also wrote-off $60,000 of uncollectible accounts receivable during the year. Past experience indicates that the allowance should be 3% of the balance in receivables. If the accounts receivable balance at December 31 was $300,000, what is the required adjustment to the Allowance for Doubtful Accounts that is needed at year-end?
