While auditor attestation of the effectiveness of internal control over financial reporting (ICFR) is required for firms with a public float of at least $75 million (accelerated filers), the Securities and Exchange Commission (SEC) has delayed auditor attestation for non-accelerated filers several times. The Dodd-Frank Act of 2010 exempts non-accelerated filers from auditor attestation. We examine the relation between auditor attestation and revenue quality for a sample of non-accelerated filers and small accelerated filers. We find that discretionary (abnormal) revenues, our proxy for revenue quality, are lower by about 1.5 percent of total assets for accelerated filers relative to non-accelerated filers. This finding holds even among firms whose management has certified their ICFR to be effective. Overall, the findings support the notion that auditor attestation of the effectiveness of ICFR benefits small accelerated filers via higher revenue quality. We believe our findings are timely and potentially informative to regulators, investors, and others.
