Final answer:
Internal controls over year-end cash balances in the general account can be divided into preventive controls and detective controls.
Step-by-step explanation:
Internal controls over year-end cash balances in the general account can be divided into two categories: preventive controls and detective controls. Preventive controls are designed to reduce the risk of errors or fraud occurring in the first place. Examples of preventive controls include segregation of duties, physical security measures, and proper authorization and approval processes. Detective controls, on the other hand, are designed to identify errors or fraud after they have occurred. Examples of detective controls include reconciliations, audits, and regular monitoring of cash balances.
