Observed effectiveness of the COSO 2013 framework

Purpose - This paper aims to examine the effectiveness of the Committee of Sponsoring Organization’s 2013 Framework, by investigating how the number of auditor-reported material weaknesses compares for Early-, Timely- and Late-adopters of the framework, and how the number of auditor-reported material weaknesses changed for Early- and Timely-adopters following their adoption of the framework. Design/methodology/approach - The paper uses regression analyses based on a sample of US firms subject to Sarbanes-Oxley Act Section 404(b). Findings - Timely-adopters of the 2013 Framework continued to exhibit fewer instances of auditor-reported material weaknesses than Late-adopters, even though they had a marginal increase in the number of auditor-reported material weaknesses, in the post-2013 Framework period. Practical implications - The findings suggest that the effectiveness of the 2013 Framework may lie in the iterative nature of the internal control process, and as firms remedy deficiencies they or their auditors identify, they will continuously improve the effectiveness of their internal control systems. Originality/value - Unlike existing literature, this paper uses data from the pre-2013 Framework, transition and post-2013 Framework periods to examine changes in the number of auditor-reported material weaknesses, thus differentiating between Early-, Timely- and Late-adopters of the 2013 Framework. It also shows the effect of adopting the 2013 Framework on the number of auditor-reported material weaknesses.
