Problem:
Innovative Tech Inc. (ITI) uses the percentage of credit sales method to estimate bad debts each month and then uses the aging method at year-end. During November 2013, ITI sold services on account for $100,000 and estimated that ½ of one percent of those sales would be uncollectible. At its December 31 year-end, total Accounts Receivable is $89,000, aged as follows: (1) 1-30 days old, $75,000; (2) 31-90 days old, $10,000; and (3) more than 90 days old, $4,000. Experience has shown that for each age group, the average rate of uncollectibility is (1) 10 percent, (2) 20 percent, and (3) 40 percent, respectively. Before the end-of-year adjusting entry is made, the Allowance for Doubtful Accounts has a $1,600 credit balance at December 31, 2013.
