分量回歸實證結果如下:(1) 假說一實證結果中,僅發現在 Q5、Q25、Q50、Q75之超額負債資金成本條件下,重編客戶(Res)與應變數呈顯著正相關,未能完全支持財報重編客戶相較於非重編客戶會產生較高之負債資金成本之假說。(2) 針對財報重編公司樣本,發現僅於特定超額負債資金成本條件下,結果達顯著水準,同樣未能完全支持發生財報重編後相較於重編前會產生較高負債資金成本之假說。(3) 針對全部樣本及非重編客戶樣本,實證結果發現,不論在何種超額負債資金成本條件下,結果皆未達顯著水準,未能支持假說,受到涉及財報重編的會計師所查核之其他非重編客戶同樣會受到負面影響。;Recently, financial restatements have become more frequent among the industry. Much of the research into restatements has focused on the reasons that lead to restatements, and the impact of restatements on investors, market and corporate itself. From the perspective of corporate, this study explores the relationship between financial restatements and cost of debt. Furthermore, we examine whether an auditor involved with restatements will has a negative effect on not only their reputation but also their clients. The study aims to investigate the effect of auditor involved with restatements on the restating and non-restating clients’ cost of debt in the subsequent years.
We conduct the research with Quantile regression method. (1) According to the tests of hypotheses, the results are only statistically significant under specified conditions. The hypotheses one “restatement clients’ have higher cost of debt than non-restating clients’ “ can’t totally be supported. (2) The tests of hypotheses show that after the restatement announcement date, restatement clients will have higher cost of debt than before. However, the result only statistically significant under specified conditions. The second hypothesis can’t entirely be supported. (3) In addition, we don’t find the result that even clients not directly
involved with restatements, they will suffer from negative effect of high cost of debt due to the fact that non-restating clients hire the same auditor as restatement clients.
