چکیده (انگلیسی):

The present research investigates the relationship between the restated accounting figures and
persistence of financial performance of the companies listed in the Tehran Stock Exchange. In order to measure the
persistence of financial performance three ratios of quick ratio, leverage ratio, and profit margin ratio are used. To
measure the value of restated figures, the difference between the absolute value of reported current asset and
restated current asset, and between the reported current liability and restated current liability, and between the
reported profit and restated profit are used. The statistical population includes 79 member companies of the Tehran
stock exchange and the time period is between 2007 and 2011. The applied statistical model is simple and multivariate regression. The results show that there is not solely significant relationship between the absolute value of
restated current asset, current liability and profit, and the persistence of financial performance. The results also
show that when the financial leverage enters into the model as a control variable, the significant relationship is
created between absolute value of restated current asset in the first hypothesis, and the absolute value of restated
profit in the third hypothesis and the persistence of financial performance in the domain of assets and profit, so that
both factors have positive relationship with the persistence of financial performance. It means that by increasing
accounting changes, the persistence of financial performance increases, while increasing financial leverage results in
reduction of the persistence of financial performance.
