Why We Rotate Engagement Partners Every Five Years, Whether You Ask or Not

PCAOB rules require partner rotation only for issuers — public companies. Nothing requires it for the private and nonprofit clients that make up most of our audit practice. We do it anyway, and clients occasionally push back, because a five-year relationship with an audit partner who knows the business well feels like an asset worth keeping.

It is an asset, and it’s also exactly the risk the rotation rule exists to manage. Familiarity is efficient and it is also the precise condition under which an auditor stops asking the question they’d ask a stranger’s financials. A new partner reviewing five years of prior workpapers catches things a continuing partner’s institutional memory quietly explains away.

We’ve had clients leave over this policy. We’ve kept it anyway, because the alternative — an audit opinion that’s more a professional friendship than an independent examination — isn’t a service we’re willing to sell, regardless of what a client would prefer to buy.
