The World Has Changed—Have Analytical Procedure Practices?
通过访谈四大会计师事务所的36名审计师，研究过去十年间分析性程序的变化，发现技术推动下审计师更多依赖行业和分析师数据，萨班斯-奥克斯利法案也影响了内部控制考量。
Analytical Procedures (APs) provide a means for auditors to evaluate the “reasonableness” of financial disclosures by comparing a client’s reported performance to expectations gained through knowledge of the client based on past experience and developments within the company and its industry. Thus, APs are fundamentally different than other audit tests in taking a broader perspective of an entity’s performance vis‐à‐vis its environment. As such, APs have been found to be a cost‐effective means to detect misstatements, and many have argued that a number of prior financial frauds would have been detected had auditors employed effective APs. With several dramatic and far‐reaching developments over the past decade, the current study examines whether and how APs have changed during this period. In particular, we focus on the impact of significant “enablers” and “drivers” of change such as technological advancements and the enactment of the Sarbanes‐Oxley Act. We also compare our findings to an influential study of the practices of APs by Hirst and Koonce (1996) that was conducted over 10 years ago. We interview 36 auditors (11 seniors, 13 managers, and 12 partners) from all of the Big 4 firms using a structured questionnaire. The data reveal some similarities in findings when compared to prior research (e.g., auditors continue to use fairly simple analytical procedures). However, there are a number of significant differences reflecting changes in AP practices. For instance, as a result of technology auditors now rely more extensively on industry and analyst data than previously. Further, auditors report that they develop more precise quantitative expectations and use more non‐financial information. They also appear to rely more on lower level audit staff to perform APs, conduct greater inquiry of non‐accounting personnel, and are willing to reduce substantive testing to a greater extent as a result of APs conducted in the planning phase. Finally, the Sarbanes‐Oxley Act has had an impact in greater consideration and knowledge of internal controls, which is seen as the most important factor driving the use and reliance on APs.
