Prepare the journal entry required at year-end to record the bad debt expense under each
of the following independent conditions. Assume, where applicable, that Allowance for Bad
Debts had a credit balance of $5,500 immediately before these adjustments.

Required:
1. Use the direct write-off method. (Assume that $60,000 of accounts are determined to be
uncollectible and are written off in a single year-end entry.)
2. Based on experience, uncollectible accounts existing at year-end are estimated to be 3% of
total accounts receivable.
3. Based on experience, uncollectible accounts are estimated to be the sum of:
1% of current accounts receivable
6% of accounts 1-30 days past due
10% of accounts 31-60 days past due
20% of accounts 61-90 days past due
30% of accounts over 90 days past due
