In all audits, the auditor should obtain an understanding of internal control sufficient to plan the audit by performing procedures to understand the design of controls relevant to an audit of financial statements and determining whether they have been placed in operation. In obtaining this understanding, the auditor considers how an entity’s use of information technology (IT) fn 2 and manual procedures may affect controls relevant to the audit. The auditor then assesses control risk for the assertions embodied in the account balance, transaction class, and disclosure components of the financial statements.
