Staff at the U.S. Securities and Exchange Commission (SEC) conduct recurring reviews of firms’ filings to deter misconduct and facilitate investor access to high-quality information. We identify the names of SEC staff who work on a comment letter and examine whether their prior involvement (i.e., continuity) is associated with comment letter quality. Our results are consistent with continuity leading to lower-quality comment letters. Continuity is associated with fewer substantive comments, agreed-upon disclosure changes, and greater similarity between consecutive comment letter reviews. These results are consistent with continuity increasing staffs’ tendency to focus on familiar issues and overlook other areas of potential deficiencies. Time, changes in firms’ operations, and increasing staffs’ feelings of accountability can mitigate the negative effect of continuity on comment letter quality. Our study suggests benefits to a fresh perspective in regulatory monitoring.

We examine whether the Financial Accounting Standards Board (FASB) Codification made it easier for preparers and auditors to locate relevant accounting guidance. We find that areas of U.S. GAAP with more dispersed and voluminous guidance before the Codification experience a larger post‐Codification reduction in restatements. We find a similar decline in SEC comment letter questions referencing areas of U.S. GAAP with more dispersed and voluminous pre‐Codification guidance. Our results suggest that before the Codification, preparers and auditors had difficulty in locating the appropriate accounting guidance and that the Codification mitigated this difficulty.
