The PCAOB inspects auditors who work for public companies. They release reports on these audits, which can be clean, GAAS-deficient, or GAAP-deficient. Clients of auditors with GAAP-deficient reports are more likely to switch to auditors without issues. This is especially true when there are agency conflicts, an expert audit committee, or outside blockholdings. However, clients don't use these reports to get discounts or better treatment in the future. These reports have created differences in the reputation of auditors who are not Big N or national firms.
