Today, successful economic firms for rapid response to commercial alteration should meet the need of users and supply information required for management in an appropriate manner so that by a suitable definition of organization relative advantages, they would be able to have a rapid accountability to needs of customers and users of financial statement and to put the reduction of costs in their agenda. Thus, there are considerable alterations in the manner in which financial reporting is presented in evaluating the performance and financial and non-financial reporting. In fact, today, reporting should keep the pace with change of users’ needs;otherwise it loses its efficiency and effectiveness. This can be of high

importance when we consider the survival of accounting job dependent on accepting fundamental changes in line with changed made in economic firms and world commercial milieu. Many studies have been done over recent three decade about quality of reporting and its desirable limit (Verdy, 2006).

Risk of crash of stock price in the market is one of greatest concerns of investors and many studies addressed the importance of this in different stock exchanges markets around the world, because stock price crash can be important for capital market as its intensification gives rise to pessimism of investors about investing within stock exchange, finally it leads to bringing the capital out of the stock exchange and it deteriorates the stock exchange market. Theoretic basics show that high quality of reporting can reduce this risk (Ferughi et al, 2012).


Quality of financial information and reporting serves always as most effective variables in determining the investment strategy in financial markets. However, managers as responsible of providing financial statement tend to distort financial information in favor of their interests. Among measures of managers resulting in low quality of financial information is manipulation of earnings. Within earning manipulation, managers attempt to accumulate the negative news in the firm so as not to reveal it. When this mass of negative accumulated news reaches to its peak it flows to the market suddenly and leads to stock price crash. Therefore, one can say that low quality of financial reporting increases the risk of stock price crash. The main objective in this study is examining the effect of quality of financial reporting on future risk of stock price crash in firms listed in Tehran stock exchange over 6-year period. A hypothesis is set forth based on study objectives and it is analyzed in section 4 by collecting information of 131 firms over study period. In the following, hypothesis results are studied.

Hypothesis: quality offinancial reporting has direct influence on future risk of stock price crash.

Considering the findings from section 4, it is specified that level of significance of quality of earning variable as indictor of quality of financial reporting is less than error level 0.05 ( value of coefficient is -0.0000152 with level of significance 0.000). therefore it can be concluded that this variable has significant effect on stock price future crash risk. Similarly, as minus sign implies, as quality of earning is higher, risk of stock price future crash would be lower. Therefore, based on earlier discussion, one can say that hypothesis “ quality of financial reporting has significant effect on risk of stock price future crash” is confirmed with 95 % confidence. By studying literature review it can be concluded that current paper results are similar to that of Raj Gupal & Venakata Chalam’s (2011) and Hutton et al (2009) studies.
