1.	Determine the number of days past due for each of the preceding accounts. If an account is not past due, enter a zero.
2.	Complete the aging of receivables schedule by adding the omitted accounts to the bottom of the schedule and updating the totals.
3.	Estimate the allowance for doubtful accounts, based on the aging of receivables schedule.
4.	Assume that the allowance for doubtful accounts for Trophy Fish Company has a debit balance of $4,700 before adjustment on December 31. Journalize the adjusting entry for uncollectible accounts. Refer to the Chart of Accounts for exact wording of account titles.
5.	Assume that the adjusting entry in (4) was inadvertently omitted, how would the omission affect the balance sheet and income statement?
