TL;DR: In this paper, the authors use unaudited pre-SOX 404 disclosures and audit opinions to assess how changes in internal control quality affect firm risk and cost of equity, and find that firms with internal control deficiencies have significantly higher idiosyncratic risk, systematic risk, and costs of equity.
Abstract: The Sarbanes-Oxley Act (SOX) mandates management evaluation and independent audits of internal control effectiveness. The mandate is costly to firms but may yield benefits through lower information risk that translates into lower cost of equity. We use unaudited pre–SOX 404 disclosures and SOX 404 audit opinions to assess how changes in internal control quality affect firm risk and cost of equity. After controlling for other risk factors, we find that firms with internal control deficiencies have significantly higher idiosyncratic risk, systematic risk, and cost of equity. Our change analyses document that auditor-confirmed changes in internal control effectiveness (including remediation of previously disclosed internal control deficiencies) are followed by significant changes in the cost of equity that range from 50 to 150 basis points. Overall, our cross-sectional and intertemporal change test results are consistent with internal control reports affecting investors' risk assessments and firms' cost of equity.

06 Jul 1993TL;DR: In this article, a method of detection of nucleic acid (DNA or RNA) target sequence in which such a sequence serves as a cofactor for a catalytic reaction in which a complementary, labeled NCA probe is cleaved such that the target sequence is released intact and can repeatedly recycle through the reaction pathway, thereby providing signal amplification.

TL;DR: This study further illustrates the power of linking proteomic networks and human genetics to uncover critical disease pathways and identified ATXN10 and TCTN2 as new NPHP-JBTS genes, and the Tctn2 mouse knockout shows neural tube and Hedgehog signaling defects.

TL;DR: In this article, a diffuse interface model is presented for direct numerical simulation of microstructure evolution in solidification processes involving convection in the liquid phase, where the solidification front is treated as a moving interface in the diffuse approximation.
