Auditor rotation
The corporate-governance rule that a company's statutory auditor must be changed at least once every five years, so a long-standing relationship cannot let facts stay hidden.
In plain language
An auditor who has worked with the same company for many years can grow too comfortable with its management. That familiarity can make it easier for problems to stay hidden, even without anyone intending fraud.
Auditor rotation forces a fresh set of eyes onto the accounts on a regular schedule, so a long relationship cannot become a blind spot.
How it works
The workbook: "It is necessary that auditors are rotated once in five years. This would ensure that there is an opportunity to find any facts concealed by the management in connivance with an auditor."
Auditor rotation and the auditor independence test work together but check different things — rotation is about tenure, independence is about fee dependence — and both sit inside the same nine-point governance checklist the workbook sets out for analysts.
A worked example
Illustrative. Company X has used the same statutory audit firm continuously since FY2016. By the current NISM syllabus period, that relationship has run roughly a decade — two full five-year rotation cycles overdue by the workbook's rule.
An analyst reviewing Company X's annual report checks the auditor's appointment history in the notes to accounts specifically to catch this — a tenure well beyond five years, with no rotation, is itself a governance red flag worth investigating further, even before looking at the numbers the auditor has signed off on.
Why NISM asks about it
Chapter 7.6.2(v) sets out the five-year rotation rule. Expect a direct question on the figure itself, or a scenario giving an auditor's tenure and asking whether the company is compliant.
Common exam traps
- Auditor rotation (tenure) and auditor independence (fee dependence) are two separate checks, often tested together as a pair — a company can pass one and fail the other.
