خلاصة:
The aim of this research is to examine the characteristics of companies whose managers smooth their earnings using discretionary accruals. In this study, smoothing and non-smoothing companies are first distinguished, and then their characteristics are tested in the form of five hypotheses. The impact of company size variables (natural logarithm of market value), debt ratio, performance (return on assets), growth (market value to book value of equity ratio), and company age on smoothing is tested. The results of the analysis from statistical tests, including the two-sample mean comparison test and multivariate regression analysis in the form of logistic regression, showed that in the Tehran Stock Exchange, smoothing companies have weaker performance, higher debt ratios, and older ages. Weaker performance and higher debt ratios indicate a higher motivation for earnings smoothing by these companies.

The impact of company size variables (natural logarithm of the company's market value), debt ratio, performance (return on assets), growth (market value to book value of equity ratio), and company age on smoothing is tested.
The results of the analysis from statistical tests, including the two-sample mean comparison test and multivariate regression analysis in the form of logistic regression, showed that in the Tehran Stock Exchange, smoothing companies have weaker performance, higher debt ratios, and higher ages.
Then, the results of the univariate test for the difference in means between the two populations (smoothing and non-smoothing) for all hypotheses at both operating profit and net profit levels are presented, followed by the results of the logistic regression model with a simultaneous test of the impact of independent variables on the dependent variable.
Table 5: Classification table at the operating profit and net profit levels (Refer to the page image) 7-Conclusion This research examines earnings smoothing in manufacturing companies listed on the Tehran Stock Exchange during the period from 1387 to 1389.
Based on the univariate test and logistic regression, the debt ratio and performance (profit divided by total beginning assets or ROA) variables at both profit levels and the age variable at the level of operating profit have a significant impact on smoothing, but based on the results of this research, other variables including size and growth do not have a significant effect on smoothing.
