Comment Letter to the PCAOB on QC 1000 Targeted Amendments

The CAQ continues to support the objective of QC 1000. A firm’s system of quality control (QC system) is foundational to audit quality, and a rigorous, risk-based, and well-operating QC system can help promote consistent execution of quality audits. At the same time, requirements that are unclear, insufficiently scalable, or difficult to operationalize may divert resources from activities that most directly support audit quality.

Accordingly, we support the targeted refinements proposed by the PCAOB in its supplemental request for comment on proposed amendments to QC 1000, A Firm’s System of Quality Control. These proposed amendments will improve coherence with other quality management standards, reduce unnecessary implementation complexity, and maintain accountability for achieving the reasonable assurance objective of the QC system.

The proposed amendments are balanced and responsive to many implementation challenges our member firms have experienced. In particular, we support rescinding the design-only requirement for PCAOB registered firms that do not perform PCAOB engagements; providing additional flexibility in assigning and dividing specified QC roles; rescinding the External QC Function (EQCF) requirement; narrowing and clarifying certain communication requirements relating to metrics; refining the evaluation of engagement deficiencies and the definition of QC deficiency; allowing firms to select their annual QC system evaluation date; revising the evaluation conclusions to align more closely with other quality management standards while retaining a structured evaluation process; clarifying documentation retention requirements and reducing the retention period to five years; and maintaining the current effective date.

We continue to encourage the Board to provide additional written implementation guidance, including potential FAQs, to support consistent application of QC 1000. Firms have engaged in ongoing discussions with Board staff regarding implementation questions, and those conversations may provide valuable insights into areas where additional clarification could be helpful. Publishing FAQs that reflect common questions and observations arising through implementation would help promote consistency across firms and ensure broader access to interpretive guidance. We welcome the opportunity to support the Board’s efforts. Providing additional opportunities for practitioner input and two-way dialogue, including before the final release, would further facilitate effective and consistent implementation of the standard.
