Lin's Dairy uses the aging approach to estimate bad debt expense. The ending balance of each account receivable is aged on the basis of three time periods as follows: (1) not yet due, $16,800; (2) up to 120 days past due, $5,500; and (3) more than 120 days past due, $4,200. Experience has shown that for each age group, the average loss rate on the amount of the receivables at year-end due to uncollectibility is (1) 3 percent, (2) 15 percent, and (3) 35 percent, respectively. At the end of the current year, the Allowance for Doubtful Accounts balance is $800 (credit) before the end-of-period adjusting entry is made. Required: What amount should be recorded as Bad Debt Expense for the current year? (Enter your answers as a whole percentage (i.e., 0.12 should be entered as 12).) (Hint: Fill out the top of the table like a typical aging table. The last line in the table should show your calculated Bad Debt Expense. Use the line in-between to show any other information needed to determine the Bad Debt Expense (if necessary)) Aged Accounts Receivable Estimated Percentage Uncollectible Estimated Amount Uncollectible Not yet due Up to 120 days past due Over 120 days past due
