Final answer:
Certain accounts require confirmation from outside sources, such as borrowers for Notes Receivable, lending institutions for Mortgages Payable, and creditors for Accrued Liabilities.
Step-by-step explanation:
Accounts that should be confirmed with outside sources include:
- Notes Receivable: Confirmation should be obtained from the borrowers, verifying the accuracy of outstanding balances, terms, and the existence of any collateral.
- Mortgages Payable: Confirmation should be obtained from lending institutions, ensuring the accuracy of outstanding balances, interest rates, and terms of repayment.
- Property, Plant, and Equipment: While not commonly confirmed with outside parties, appraisers could be used to verify fair market value of tangible assets, though this is generally not required for annual audits.
- Accrued Liabilities: Confirmation should be obtained from creditors, double-checking the accuracy of the obligations and the payment terms.
