Principles-Based versus Rules-Based Accounting Standards: The Influence of Standard Precision and Audit Committee Strength on Financial Reporting Decisions

Recent accounting scandals have resulted in regulatory initiatives designed to strengthen audit committee oversight of corporate financial reporting and have led to a concern that U.S. GAAP has become too rules-based. We examine issues related to these initiatives using two experiments. CFOs in our experiments exhibit more agreement and are less likely to report aggressively under a less precise (more principles-based) standard than under a more precise (more rules-based) standard. Our results also indicate that CFOs applying a more precise standard are less likely to report aggressively in the presence of a strong audit committee than a weak audit committee. We find no effect of audit committee strength when the standard is less precise. Finally, we find support for a three-path mediating model examining mechanisms driving the effect of standard precision on aggressive reporting decisions. These results should be of interest to U.S. policymakers as they continue to contemplate a shift to more principles-based accounting standards (e.g., IFRS).
