Abstract:	我國財務會計準則委員會於民國93年7月1日公佈了財務會計準則公報第 35號「資產減損之會計處理準則」，基本上該公報係沿循IAS No.36的精神而制定，主要目的為了使企業資產價值能真實地反應、提升財務報表透明度及與國際接軌。採取事件研究法之市場模型檢定財務會計準則第35號公報公布事件是否對台灣股票市場造成影響，並且檢驗是否會造成顯著異於0之異常報酬，以公報之公布日作為事件日，宣告日前後各30日作為事件期。實證結果如下: 1.公報之公布對全體樣本有顯著異常報酬產生，在公布日前後有顯著負異常報酬。透過不同事件期設定進行比較，由觀察累積異常報酬中發現，不同事件期對分析結果並無影響。 2.公報公布事件對於電子、金融保險產業亦會產生顯著負異常報酬。 On July 1, 2004, R.O.C FASB issued the Impairment of Assets Accounting Statement -- Statement No.35. Basically, Statement No.35 is considerably equivalent to IAS 36. The purpose of Statement No.35 issuance is to reflect the true value of enterprise assets, improving the transparency of the financial report, and bring Taiwan more closely in line with international trends. Market model of Event Studies has been applied to analyze the stock price variations before and after the issuance of the SFAS No.35. The purpose of the thesis is to examine whether if the abnormal returns are significantly higher than zero. Using the issuance date July 1, 2004 as the event date and the event period being the 30-days before and after the issuance date. Major findings can be summarized as follows: 1.The effect of Statement No.35 issuance shows significant abnormal returns for whole sample. During the event period, there are significant negative abnormal returns before and after the event date. Comparing the effect of cumulative abnormal returns in different event periods, we found different event periods do not influence the results. 2.There exist significant and negative abnormal returns for the electronic, finance and insurance industries around the issuance of Statement No.35 event.
