Is a QoE governed by AICPA standards?
No. A quality of earnings report is a consulting engagement, not an attest engagement, and no explicit AICPA standards govern its scope or its deliverable. That has two consequences people routinely get wrong: a QoE carries no audit opinion and no assurance, and whether a buyer may rely on a seller-commissioned QoE is a contract question — a reliance letter — rather than a professional-standards question.
