Subject: Business
Grade: College
An auditor is required to communicate the following matters to those charged with governance: b. The process used by management in formulating sensitive accounting estimates. This includes discussing the methods and assumptions used by management to arrive at accounting estimates that may have a significant impact on the financial statements. The auditor should communicate any concerns or uncertainties regarding the estimates.
Additionally, the auditor should also communicate: d. The justification for performing substantive procedures at interim dates. This involves explaining the reasons for conducting substantive procedures at specific points in time before the completion of the audit. It helps those charged with governance to understand the timing of audit procedures and their rationale.
The other two options, a and c, are not matters that auditors are required to communicate to those charged with governance.
