Internal control material weakness, analysts’ accuracy and bias, and brokerage reputation

Abstract

The main purpose of this paper is to examine the impact of internal control material weaknesses (ICMW hereafter) on sell side analysts. We find that ICMW reporting firms have less accurate analyst forecasts relative to non-reporting firms when the reported ICMWs belong to the Pervasive type. ICMW reporting firms have more optimistically biased analyst forecasts compared than non-reporting firms. The optimistic bias exists only in the forecasts issued by the analysts affiliated with less-highly-reputable brokerage houses. The differences in accuracy and bias between ICMW and non-ICMW firms disappear when ICMW disclosing firms stop disclosing ICMWs. Collectively, our results suggest that the weaknesses in internal control increases forecasting errors and upward bias for financial analysts. However, a good brokerage reputation can curb the optimistic bias.
