Assuming it has RMB 1400 credit balance . 13400-1400=12000 Dr. financial expense 12,000 Cr. Allowance for doubtful expense 12000 3. If the company use income statement expense. 200,000*3%= 6,000 C) 1. Dr. note receivable 22,000 Cr. account receivable 22,000 2. Dr. interest receivable 22,000*12%/4=660 Cr. interest revenue 660 Dr. Cash 22 660 Cr. note receivable 22 000 interest receivable 660 Question 4 Why do we need to prepare bank reconciliation? Because the timing of transaction between bank and the accounting book is different.
