Auditors of US issuers classified as large accelerated filers with yearends on or after June 30, 2019 are required to consider inclusion of critical audit matters (CAMs) in their audit reports. We survey the audit engagement partners, audit committee chairs, and chief financial officers of certain US issuers to gain insight into the process of identifying and reporting CAMs. We also gather perceptions about the impact of disclosing CAMs on audit effectiveness and efficiency. Our results provide initial evidence that the CAM reporting process is largely controlled by the independent auditor. They also provide mixed evidence about concerns expressed during the comment phase of the proposed auditing standard: The CAM process increases audit fees, but it does not adversely impact audit quality. Stakeholders participating in the CAM process question whether reporting CAMs adds enough, if any, value to justify its costs.

年期在2019年6月30日或之后的美国发行人的审计师被归类为大型加速备案者，必须考虑在其审计报告中包括关键审计事项（CAM）。我们对某些美国发行人的审计业务合作伙伴，审计委员会主席和首席财务官进行了调查，以深入了解识别和报告CAM的过程。我们还收集了有关公开CAM对审计有效性和效率的影响的看法。我们的结果提供了初步的证据，表明CAM报告过程在很大程度上由独立审计师控制。他们还提供了有关在提议的审计标准的评论阶段表达的关注的混合证据：CAM过程增加了审计费用，但不会对审计质量产生不利影响。
