Abstract

Abstarct



Todays one of the most important factor for dicision making process by market participants at Tehran Stock Exchange listed companice is the information published by the companies listed in If the information is not properly disclosed, without a doubt, the price discovery mechanism in the market will not work properly and the pricing of the bonds will not be done in a favorable way. Therefore, according to the importance of the level of disclosure, it is important to identify the factors affecting the quality of disclosure, therefore, in this research, the impact of credit rating changes on the quality of disclosure has been investigated. In order to carry out the research, a sample consisting of 126 companies listed in Tehran Stock Exchange during the period of 2012 to 2021 were examined. In order to perform the analysis, the data related to the credit rating, disclosure quality rating and control variables were extracted from Rahvard Navin software and the accompanying notes of the financial statements. Based on the results of the research, there is a negative relationship between credit rating changes and disclosure quality. In other words, credit rating changes are effective on the voluntary disclosure level of companies, but this effect was not statistically significant. While there was a negative and significant relationship between credit rating and disclosure quality. In other words, the higher the credit rating, the lower the company's disclosure quality. The higher the credit rating, because investors evaluate the risk as low, their demand for more information disclosure also decreases. In other words, increasing the credit rating through reducing the demand for information can lead to a reduction in disclosure.
