Does investment efficiency improve after the disclosure of material weaknesses in internal control over financial reporting?☆

Abstract

We provide more direct evidence on the causal relation between the quality of financial reporting and investment efficiency. We examine the investment behavior of a sample of firms that disclosed internal control weaknesses under the Sarbanes-Oxley Act. We find that prior to the disclosure, these firms under-invest (over-invest) when they are financially constrained (unconstrained). More importantly, we find that after the disclosure, these firms’ investment efficiency improves significantly.
