Non-electronics firms as a group in the same period were also investigated for comparison purpose. Discretionary accruals were regarded in this study as a tool for earnings management. While examining the earnings distribution, this study found that firms manage reported earnings to avoid losses. In particular, the finding indicated unusually low frequencies of small losses and unusually high frequencies of small positive earnings. As to the factors that influence the discretionary accruals, this study showed a significantly negative association between income before discretionary accruals and the extent of earnings management. This study, however, did not document the evidence that corporate governance mechanism mitigated the earnings management behavior. Interestingly, this study found that firms with poorer earnings (the lower ten percentile) tend to manage earnings upward, which is inconsistent with the big bath phenomenon reported in some previous studies. Overall, both electronics and non-electronics firms were found to have similar earnings management behavior, although non-electronics firms seemed to manipulate more aggressively. Lastly, this study provided evidence on the value relevance of non-discretionary accruals and discretionary accruals.application/pdf73558 bytesapplication/pdfzh-TW國立臺灣大學會計學系暨研究所電子業盈餘分佈盈餘管理資訊內涵裁決性應計項Electronics industryearnings distributionearnings managementinformation contentdiscretionary accrualsreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/18390/1/892416H002064.pdf
