This study investigates the following questions: which item of restatements have the most frequency? Are the nature and types of restatements different among years and industries. And, is there a significant difference between primary and restated figures? The results, based on 1603 firm-Years observations of listed companies in Tehran securities exchange, indicate that the most frequency of restatements have occurred in liabilities, car industry, and the year of 2005. The findings also show that the types and nature of the restatements are different through the years and industries. In addition there is a significant difference between primary and restated figures. Thus we suggest that researchers and analysts use restated data for financial reviews and analysis. Finally the significant difference of primary and restated amount of the “beginning retained earning” shows that the retroactive restatement must be extended beyond one year, especially for key items such as EPS and operating net income.

This research is aimed to investigate the effect of accounting restatements on cash holding policy. Firms often hold significant amounts of cash in their balance sheets due to capital market defects such as information asymmetry, agency problems, transaction costs, and external financing costs. On the other hand, accounting restatements can affect the level of cash holdings and its market value. This research is a causal, post-event and applied one. The sample consists of 155 firms listed in the Tehran Stock Exchange during the period from 2009 to 2016. Findings based on the multivariate linear regression analysis show that, according to the strengthened control theory, accounting restatements lead to a decrease in cash holdings. Also, in line with the agency theory, restatements of financial statements will lead to a decrease in the market value of cash holdings from investors' perspective. In other words, investors interpret the accounting restatements as a negative signal.
