Securities and Exchange Organization (SEO) of Iran has newly ranked audit firms into four categories (first, second, third and fourth). Based upon the instructions of audit firms’ ranking issued by SEO, the audit quality of “First” category audit firms is more likely to be higher than that of audit firms of other categories. However, an unanswered research question is whether or not such claim of the SEO is correct. In an effort to respond to the question, the present study examines 1,706 firm-year observations collected from annual reports of firms listed on Tehran Stock Exchange between 2001 and 2010. The type of audit opinion and the number of audit remarks embedded in audit reports are utilized as the two measures of audit quality. Multivariate regression analysis reveals that the audit firms of “First” category do not issue modified audit opinions more than audit firms of other categories. Nonetheless, the main findings indicate that the number of audit remarks embedded in modified audit reports audit reports is higher for the audit firms of “First” category. The results of the present study are robust after utilizing several sensitivity tests.
