The PCAOB’s May 2015 release of its Audit Committee Dialogue provides audit committee members of publicly traded companies with insight into concerns that have consistently arisen in discussions between audit committees and auditors over the past few years. In addition, the PCAOB identifies areas which are emerging as potential risks to be addressed by audit committees and their auditors.
Recurring Areas of Concern
The examination of over 650 audit firms across six global networks revealed four main areas of concern which have consistently appeared during the years evaluated. These areas are categorized as internal control over financial reporting (ICFR), material misstatement risk assessment and response, accounting estimates (including fair value), and deficient “referred” work performed by one auditor but used by another.
Internal control over financial report (ICFR) has been the most common area of concern over the four years 
The second common topic of concern discussed is that of deficiencies in assessing and responding to risks of material misstatement, particularly related to auditing revenue. During both 2012 and 2013, one quarter of all audits inspected were identified as failing to comply with risk assessment standards. The PCAOB emphasizes that changing risks should consequently change audit plans, and auditors should be proactive in identifying changes which may alter a company’s risk environment.
The third significant area of concern discusses auditing accounting estimates, including fair value measurements, and their disclosures. Deficiencies in auditing accounting estimates ranged from 8% to 14% over the four years evaluated. Deficiencies in auditing fair value measurements ranged from 10% to 15%. Both sets of deficiencies resulted in insufficiently supported audit opinions and are still significant areas of concern.

Emerging Areas of Audit Risk
After discussing existing areas of audit risk concern, the PCAOB addressed areas of growing concern. First, the PCAOB identifies a significant increase in the number of mergers and acquisitions as a potential area for audit risk concern. Engagement teams may not have the experience to handle such situations properly, due to previously low levels of activity in this area. Second, the fall of oil prices is a growing concern for the PCAOB. Regardless of industry, the decline of oil prices poses a risk of material misstatement for companies. The PCAOB plans to examine how auditors approach this emerging risk. Third, the PCAOB discusses undistributed foreign earnings and potential risk related to income tax accounting. In attempts to minimize domestic tax responsibility, U.S. public companies collectively hold more than $2 trillion in indefinitely reinvested foreign earnings. Finally, the PCAOB is concerned over potential risks due to the expansion of non-audit services provided by audit firms. The recent growth of consulting services provided by large audit firms could have an effect on the firms’ attention to audit quality. In order to avoid this danger, firms must carefully manage growth in the area of non-audit work.
In summary, both the recurring and emerging areas of risk outlined above should be of concern to audit committees as they work with their auditors to strengthen audit quality. Audit committees should be aware of these areas of concern, and audit committees should actively engage in discussion with their auditors regarding these potential risks.
