The value of a company is influenced by many factors such as the weakness of internal controls and the information quality resulting from it. In the meantime, level of investment and credit rating of the company can offset the weaknesses of internal controls and prevent devaluation of the company in this respect.

This study was a descriptive- post event one in nature and method, an applied one objectively. To test the research hypotheses, 112 companies listed on the Tehran Stock Exchange for the period 2012 to 2018 were selected and studied. The results of hypothesis testing showed that internal control weakness had a negative effect on firm value and Investment has no effect on the relationship between internal control weakness and firm value but credit ratings has effected relationship between internal control weakness and firm value and increases the Firm value.
