本研究欲檢視當企業宣告財務報表重編後之影響,其是否會反應於資金成本上,並進一步檢視強制性重編是否存有強烈之差異。本研究係採台灣經濟新報(TEJ)資料庫所取得之臺灣上市公司2000年至2011年之重編及財務資料,進行迴歸分析。由於過去研究主要多採事後已實現的股票報酬,為事後權益資金成本,而此作法被近期之財務文獻認為較不精確,故本研究利用分析師及券商之預測資料來計算事前的權益資金成本;並利用TEJ信用評等(TCRI)作為債務資金成本之代理變數。本研究的實證結果發現,臺灣企業之財務報表重編與資金成本並無顯著關聯,然而當重編若為強制性時,其與資金成本卻有顯著關聯性。
This paper investigates the effect of financial restatements on the cost of equity capital for electronic industry of Taiwan. We also examine the difference between man-datory and voluntary restatements. Using Price Earnings Growth Model (PEG) to esti-mate firms’ ex ante cost of equity, the empirical results show that there was no signifi-cant association between financial restatements and cost of capital. However we also find a significant negative (positive) correlation between mandatory restatements and cost of equity (cost of debt).
