چکیده انگلیسی

The auditor is required to evaluate whether substantial doubt exists about the client entity's ability to continue as a going concern. Accounting debacles in recent years have shown the importance of proper and thorough audit analysis. Since the 80s, many studies have applied statistical techniques, mainly logistic regression, as an automated tool to guide the going concern opinion formulation. In this paper, we introduce more advanced data mining techniques, such as support vector machines and rule-based classifiers, and empirically investigate the ongoing discussion concerning the sampling methodology. To provide specific audit guidelines, we infer rules with the state-of-the-art classification technique AntMiner+, which are subsequently converted into a decision table allowing for truly easy and user-friendly consultation in every day audit business practices.

مقدمه انگلیسی

Statement on Auditing Standards (SAS) No. 59 [1] requires that on every audit the auditor evaluates whether substantial doubt exists about the client entity's ability to continue as a going concern. In particular, the auditor has to assess the client's going concern status for a reasonable period of time, not to exceed one year beyond the date of the financial statements being audited. Relevant information with respect to the continuation of an entity as a going concern is generally obtained from the application of auditing procedures that are planned and performed to achieve audit objectives. Examples of conditions and events that cast doubt on the entity's ability to survive include negative financial trends, defaults on loans or similar agreements, and non-financial internal and external matters such as work stoppages or substantial dependence on the success of a particular project. When the identified conditions and events in the aggregate lead to substantial doubt about the continued existence of the entity as a going concern, the auditor should identify and evaluate management's plans to mitigate the effects of these adverse conditions or events. If the auditor believes that there exist management plans that overcome this substantial doubt, a going concern audit report is not required. However, if the auditor decides that substantial doubt exists, the audit report should be modified by adding an explanatory paragraph following the opinion paragraph. Although the assessment of a company's viability is not the main objective of an audit, bankruptcies without a prior going concern report are often viewed by the public as audit reporting failures [35], [13] and [22]. The high frequency of this type of audit reporting failures is indicative of the fact that the auditor's going concern decision is highly complicated and involves a high level of judgment. The complexity of the going concern decision has prompted the development of numerous models to predict the issuance of a going concern opinion (see, for example, [37], [30], [17], [36] and [6]). The focus of these studies has been the development of going concern prediction models, proposing a variety of financial and non-financial variables that might be indicative of the auditor's going concern decision. Most of these prediction models were developed using regression analysis, a technique which is well suited for investigating the determinants of going concern decision-making but less appropriate for developing user-friendly going concern decision models that can be used in everyday auditing. In this paper, we address this gap in the going concern literature by building a comprehensible rule-based classification model which allows for easy consultation by auditors to assess their client's viability. The classification model developed in this study is particularly useful to auditors to screen potential clients or as a decision aid to identify severely distressed clients that might require further consideration. Moreover, auditors may use this model in the final stages of the audit engagement as a quality control device or as a benchmark to represent auditor judgment under similar circumstances. Furthermore, we will address the appropriateness of the methodology of recent going concern research. In particular, we will evaluate the performance of various data mining techniques including logistic regression and the rule-based classification technique used in this study. In addition, we will examine empirically potential estimation biases induced by the choice-based sampling methodology used in recent going concern research. We compare estimation results from a “complete data” sample with estimation results from choice-based sampling techniques currently used in going concern research. In sum, we contribute to existing going concern research by (a) developing a practical and user-friendly going concern decision-aid for audit practitioners and (b) critically reviewing the methodology of recent going concern research

نتیجه گیری انگلیسی

4. Conclusions The relevance and success of data mining for the going concern decision is driven by a number of factors. First of all, much data of previously audited firms is available, a prerequisite for any data mining application. Secondly, the going concern decision is a complex task with widespread consequences to both the company being audited and the auditor, for which decision support systems are more than welcome. This has prompted the development of numerous models to predict the issuance of a going concern opinion in the past. Finally, recent accounting debacles only stress the importance of good auditing practices, increasing the relevance of such predictive data mining models even further. In the existing literature body, the automated prediction of such opinions is commonly done with logistic regression. Although more advanced data mining techniques — which have been widely researched and applied in domains such as credit scoring, bio-informatics and marketing — were largely missing from the audit domain, we have shown the applicability and usefulness of such approaches. Decision support tools can be very helpful, though user friendliness is a key requirement as auditors are often rather skeptical to the use of statistical, rather incomprehensible models. An intuitive decision table on the other hand, can very easily be incorporated into the auditor's guidelines, assuring that going concern opinions are expressed more consistently. The rule sets induced by the ant-based classification technique AntMiner+, provide such interpretability, allowing for truly easy and user-friendly consultation in every day audit practices. Further, we empirically tested the ongoing academic discussion on sampling methodologies. Although the experiments show differences in accuracies over the different sampling methodologies, as could be expected, more interestingly the ranking among the included techniques did not change. Of course, the search for more predictive variables and more relevant data is a continuous process. For example, as the auditing firm typically has a long term relationship with its customer, it will have more data at its disposal than publicly available. The decision table proposed here can surely be complemented by the private information available, as to obtain an even more accurate model.
