Investigation of the effect of irregularity of accruals on the adjustment rate of capital structure in companies listed in the Tehran Stock Exchange

This study aimed to study the effect of irregularity of accruals on the adjustment rate of capital structure in companies listed on the Tehran Stock Exchange. This research is applied in terms of purpose and was performed by the descriptive-correlational method. By using the systematic elimination method, a sample of 106 companies was selected from the companies listed on the Tehran Stock Exchange from 2008 to 2017. Analysis and testing of the study hypothesis along with its results were performed on the results obtained from Eviews 10 software. A regression model was used to test the hypothesis. The findings indicate that the coefficient of variable capital structure (0.401) is significant at the 5% level, and the adjustment rate of capital structure is approximately 59.9% (1-0.401). The coefficient of irregularity of accruals (-0.024) at the -5% level is significant. Furthermore, the product of capital structure and irregularity of accruals (0.068) is positive and significant at the 5% level. This matter reveals that by reducing the irregularity of accruals, the adjustment rate of capital structure drops from 59.9% to 21.5%, and the significance of the coefficient of variable multiplied by the capital structure in the irregularity of accruals indicates the significance of this decrease.
