Final answer:
An organization requires unclaimed paychecks to be delivered to the internal audit department to enhance internal control and prevent potential fraud, ensuring accurate financial records.
Step-by-step explanation:
An organization might require the paymaster to deliver all unclaimed paychecks to the internal audit department in order to ensure a higher level of internal control over the payroll process. This action helps to prevent potential fraud and allows for the reconciliation of outstanding payments. The internal audit department acts as an independent verifier and can investigate why paychecks remain unclaimed, ensuring checks are not fraudulently collected and that financial records are accurate. In the scenario provided, Noel's attentiveness to noticing a $250,000 overpayment in an equipment bill illustrates the importance of having robust internal controls and checks within the financial processes of an organization.
