Abstract: In recent years, after various scandals, the role of auditors has been called into question, even casting doubt on whether their reports reliably reflect the true financial situation of the auditee, especially when this situation is not good. Normative changes in the way auditors have to rate certain questions provide a good opportunity to study this problem. These changes have acquired great relevance among the factors involved in studying audit quality. Thus, the present study analyzed the effect of the normative change that took place in Spain in December 2010, related to opinions modified for going-concern uncertainties. Until that date, the auditor’s uncertainty about the company’s going-concern status led to a qualified opinion. However, under the new regulation, it became an opinion that included an explanatory paragraph stating the reasons for concern, which was considered less serious. In all, 152 small- and medium-sized enterprises that had begun bankruptcy proceedings were studied. Expert systems were used for their analysis, based on classification trees assembled through boosting and bagging. In addition, the logistic regression was used as baseline to compare previous methods. The main result obtained was that a change in the norm that catalogs the going-concern issue as less serious made auditors more likely to report this situation, thus questioning the audit quality.
