Final answer:
Reviewing the GL account list can be both a preventative and a detective control.
Step-by-step explanation:
The act of reviewing the GL (General Ledger) account list can be categorized as both a preventative control and a detective control.
As a preventative control, reviewing the GL account list helps ensure that all necessary accounts are properly set up and that any potential errors or omissions are identified early on. It helps mitigate the risk of incorrect financial reporting or misstatements in the financial statements.
On the other hand, as a detective control, reviewing the GL account list can help identify any anomalies or discrepancies in the account balances. It acts as a monitoring mechanism to detect any inaccuracies or potential fraud that may have occurred, thereby enhancing the overall control environment.
