Conservatism is an evaluation criterion of financial reporting quality. Requesting accounting information of higher quality can be influenced by the acceptance of securities in capital market. In this study, a major and two minor hypotheses are designed. All listed companies on Tehran Stock Exchange are considered as target population of the research which are examined over a ten-year period (2006-2015). Research sample is selected considering the following criteria: continuous activity of the firm during the research period, consistency of reporting timetables to omit seasonal effects, elimination of investment and financial intermediation institutions. The achieved findings indicate that at the significance level of %95 there is a significant relationship between conditional conservatism (derived from Givoly and Hayn’s (2000) model), unconditional conservatism (derived from Beaver and Ryan’s (2000) model) and reporting quality (following Barth et al. (2001) study).
