Each year, the BAOB subjects different non-PIE auditors and audit firms to a quality assurance review. The selection consists of auditors and audit firms that are selected to comply with the oversight cycle (at least) every six years, auditors that have been identified as posing a potentially elevated risk of lower audit quality, and a possible random selection.
For 13 non-PIE audit firms whose office organisation was reviewed, and 33 non-PIE auditors of whom an audit engagement was reviewed, the BAOB Committee decided in 2024 to impose a total of 131 measures, including:
- 5 reprimands
- 34 compliance deadlines
- 40 injunctions, and
- 52 recommendations.
With a few exceptions, the measures taken by the BAOB in 2024 concerning non-PIE cases, refer to quality assurance reviews performed in 2023.
