Securities and Exchange Organization (SEO) of Iran has ranked audit firms into four categories (First, Second, Third and Fourth). Based upon the instructions of audit firms ranking, the audit quality of “First” rank 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 instructions is correct. In an effort to respond to the question, the present study examine 1,736 firm-year observations collected from annual reports of firms listed on Tehran Stock Exchange between 2001 and 2010. Discretionary accruals measured by Kothari et al. (2005), Ball and Shivakumar (2006) and Dechow and Dichev (2002) are utilized as the three indicators of audit quality. Multivariate regression analysis reveals that the absolute discretionary accruals of client firms audited by “First” rank audit firms do not less than that of the client firms audited by audit firms of other ranks (Second, Third and Fourth). That is, we find that the audit quality of “First” rank audit firms is not higher than that of other ranks’ audit firms. The results of the present study are robust after utilizing several sensitivity tests.
