Some views indicate that income smoothing can predict future performance of companies and prepare useful information for interested group. The aim of this study is to test this view in companies listed in Tehran Stock Exchange. We have followed this target by focusing on earnings persistence and divided policy persistence as proxies for anticipating companies' future performance in companies that have smoothed their earnings. Financial information was collected from a sample of 66 firms for the period of 2008 to 2012. We have used multiple linear regressions and Logistic Regressions to test our hypothesis. The results show smoothed income has significant negative impact on earnings persistence and don’t have significant impact on dividend policy persistence. These results mean earnings smoothing in TSE companies is not done with the purpose of preparing useful information for anticipating future performance.

During the past two decades business and manufacturing have observed significant and radical changes. Companies have used automation in the manufacturing, in order to improve quality and competency. It was expected that along with these changes, management accounting systems, which focus on monitoring and analyzing management decisions, should adapt with and encourage the changes.

The study demonstrates that there is more correlation between qualitative factors such as; manufacturing capabilities, improved product quality and, competition position with investment justification than quantitative bases such as; accounting rate of return (ARR), internal rate of return (IRR) and, net present value (NPV).

Calculating the cost of product precisely and presenting reliable information and reports for economic decision making are the objectives of cost accounting systems. But, the independent auditors reports reveal that most of the manufacturing companies, especially state companies, do not possess suitable methods for cost accounting of products.

The results show that the cost accounting system of the selected companies, compared to a suitable accounting system is very in appropriate. The reasons of its inappropriateness are absence of proper procedures for production cercufation, absence of accounts related to production process, absence of correct information a bout the capacity of production lines, inability to recognize costs behavior, not using proper bases for over head allocations, not using budget mechanism related to list of the bills, not colwlating and registering variances and not preparing reliable managerial reports at certain periods of time.
