碩士 === 國立政治大學 === 會計研究所 === 99 === The main purpose of this thesis is to investigate the relation among SOX302, SOX404 and the accuracy of management earnings forecasts. Using a sample of S&P listed companies during the period 2002-2009, I address the following issues: (1) whether companies with effective internal controls under SOX302 have lower earnings forecast accuracy, compared with those under SOX404; (2) in the SOX404 context, whether companies with firm-level material weaknesses have lower earnings forecasts accuracy, compared with those with account-specific material weaknesses. As predicted, my empirical results show that: (1) compared with those under SOX404, companies with effective internal controls under SOX302 have lower earnings forecasts accuracy; (2) compared with those that disclosed account-specific material weaknesses under SOX404, the companies with firm-level material weaknesses have lower earnings forecasts accuracy.
