چکیده

این مقاله به بررسی اهمیت تحقق آستانه­ی سود سال قبل از دیدگاه سرمایه­گذاران در زمان اعلام سود می­پردازد. هدف اصلی این مقاله پاسخ به این پرسش است که آیا بر مبنای نظریه­ی انتظارات، می­توان آستانه­ی سود سال قبل را به عنوان یکی از نقاط مرجع سرمایه­گذاران در نظر گرفت. برای آزمون فرضیه­ها، نمونه­ای متشکل از 75 شرکت از بین شرکت­های پذیرفته شده در بورس اوراق بهادار تهران در سال­های 1386 تا 1389 انتخاب و برای تجزیه و تحلیل داده­ها، از مدل رگرسیون چندگانه به روش داده­های ترکیبی استفاده شد. نتایج آزمون فرضیه­ی اول پژوهش نشان داد آستانه­ی سود پیش­بینی شده با بازده غیرعادی سهام رابطه­ی مستقیم دارد. نتایج آزمون فرضیه­ی دوم پژوهش نشان داد با کنترل سود پیش­بینی شده، آستانه­ی سود سال قبل به عنوان یکی از نقاط مرجع سرمایه‌گذاران در تصمیم­های سرمایه­گذاری مطرح نیست. به عبارت دیگر این پژوهش انگیزه­های مبتنی بر بازار سرمایه، به عنوان محرک مدیریت سود پیرامون دستیابی به سود سال قبل را تأیید نمی­کند.

Introduction
       Given the importance of earnings, it is no surprise that management has a vital interest in how they are reported or wanted to manage earnings. Dechow and Skinner (2000) recommend that researchers consider management’s capital market incentives to meet or beat simple earnings benchmarks, consisting of the following:
        (1) to avoid losses, that is, to report earnings that are above zero;
       (2) to avoid earnings decreases, that is, to make the earnings in the corresponding quarter of previous year; and
       (3) to avoid negative earnings surprises, that is, to report earnings that meet or beat expectations.
The main purpose of this paper is investigating the importance of achieving last year’s earnings threshold.
 
Research Question
       Prior research provides evidence that meeting (or beating) the forecasted earnings results in a differential market response compared to missing the forecast (e.g., Sajadi, 1998; Khani, 2007). This paper extends prior research by examining whether there is a market effect for meeting or missing unexpected last year’s earnings thresholds while controlling the effects of meeting or missing the forecasted earnings.
 
 
Methods
       To devise a proper test to see whether the market prices last year earnings threshold, it is important to identify the point at which the market should assign value for meeting or missing the threshold. For the vast majority of firms, reporting earnings above or below earnings increase threshold is not a surprise to the market at the time of the earnings announcement. Accordingly, two instances in which a firm’s announced earnings involve unexpectedly meeting or missing an earnings increase threshold after taking into consideration the effect of management forecasts,
       1) Unexpected increase: firms that were forecasted to have a decrease in earnings that report an increase in earnings (UINCR).
       2) Unexpected decrease; firms that were forecasted to have an increase in earnings that report a decrease in earnings (UDECR).
And four additional classifications for the expected thresholds consider:
       1) Expected increase with positive earnings forecast errors; firms that were forecasted to have an increase in earnings that report an increase in earnings (EINCRFE+). For these firms actual earnings is greater than forecasted earnings.
       2) Expected increase with negative earnings forecast errors; firms that were forecasted to have an increase in earnings that report an increase in earnings (EINCRFE-). For these firms forecasted earnings is greater than actual earnings.
       3) Expected decrease with positive earnings forecast errors; firms that were forecasted to have a decrease in earnings that report a decrease in earnings (EDECRFE+). For these firms actual earnings is greater than forecasted earnings.
       4) Expected decrease with negative earnings forecast errors; firms that were forecasted to have a decrease in earnings that report a decrease in earnings (EDECRFE-). For these firms forecasted earnings is greater than actual earnings.
       This paper examines whether there is an incremental effect for unexpectedly meeting the increase threshold for firms already reporting a positive forecast error (UINCR). This can be examined by comparing the estimated coefficients of UINCR firms with those of EINCRFE+ and EDECRFE+ firms. Evidence of an incremental threshold effect for meeting the increase threshold would be found if the intercept or slope coefficient of UINCR firms is incrementally greater than those of EINCRFE+ and EDECRFE+ firms. A similar analysis is performed for the other group (UDECR, EINCRFE-, EDECRFE-). For data analysis, panel data were used and a sample consisting of 75 companies listed in Tehran Stock Exchange during the years 2008 to 2011 were selected.
 
Results
       Results showed earnings response coefficient (ERC) for UINCR firms is more positive than ERC for EDECRFE+ but less positive than ERC for EINCRFE+ firms. This result is not consistent with a market reward for meeting the earnings increase threshold.   For missing the earnings increase threshold, the ERC for UDECR firms is greater than the ERC for EDECRFE firms but less positive than ERC for EINCRFEfirms, respectively.
Once again, the results do not provide any evidence of an incremental threshold effect.
 
Discussion and conclusion
       The results show that last year’s earnings threshold as one of the reference points is not considered in the decisions of investors. In other words, this research doesn’t support market-based incentives as a driver of earnings management on capital markets.
