Does auditor style influence non‐GAAP earnings disclosure?
研究发现，同一审计师审计的客户在非GAAP盈余披露方式上更相似，这种关联主要由四大会计师事务所和同一审计办公室的客户驱动，且对大型审计办公室和小型客户更显著。
Abstract Regulators and practitioners have concerns that the lack of standardization in non‐GAAP disclosure can make it challenging for users to process non‐GAAP earnings and use it in decision‐making. We examine whether auditor style extends beyond mandatory disclosures to induce similarity in non‐GAAP earnings disclosures. Specifically, we find that clients audited by the same auditor are more likely to disclose non‐GAAP earnings in a similar manner. We assess disclosure similarity using (1) the decision to disclose non‐GAAP earnings, (2) the disclosure prominence of non‐GAAP earnings in the earnings press release, (3) the discussion of non‐GAAP earnings in the management discussion and analysis of the annual report, (4) the choice to exclude recurring items, and (5) the receipt of SEC comment letters related to non‐GAAP earnings. We find that the association between auditor style and non‐GAAP disclosure is determined by Big 4 accounting firms and clients audited by the same audit office. The results are stronger for larger audit offices and smaller clients. We provide evidence that auditors facilitate non‐GAAP disclosure, which can improve compliance with SEC requirements and increase the standardization of non‐GAAP earnings disclosures. Our results are relevant to current policy discussions regarding auditor involvement in unaudited non‐GAAP earnings reporting.
