    [[abstract]]本研究動機起自近十年來國內外企業舞弊案件頻傳,從2001年的美國安隆、世界通訊到國內的博達、力霸、訊碟等事件都嚴重損害到廣大的投資大眾。故希望能從已進入投資人保護中心團體訴訟的案件中,選取其財務資訊,歸納出一個危機公司的常見型態,藉以作為財務危機預警之用。考量1997年的亞洲金融風暴及2008年金融海嘯可能造成資料的扭曲,加上台灣上市櫃公司之財務資料日趨完整,故選取近五年自2009至2013年間台灣上市櫃且具有完整財務資料之公司,資料來源為台灣經濟新報公司財務資料庫,挑選財團法人證券投資人及期貨交易人保護中心團體訴訟勝訴案例中的科技業公司15家作為危機公司。另外,本研究採2009年至2013年之財務資料進行建模,再以羅吉斯迴歸進行分析。研究過程中為了加強模型可用性,所以另外使用了15家上市櫃正常公司來進行對照,正常公司樣本是選自TEJ資料庫中台灣前五十大企業中的電子科技業,依據與危機公司的產業類別相同所配對而來。實證結果顯示,無論是以台灣50或是產業相應樣本皆可發現財務結構與償債能力之預測變數具顯著性,顯示危機發生應將注意力放在這些指標上。可提醒投資人在面對危機預警時,可以觀察負債比率、長期資本適合率、流動比率、速動比率、現金流量允當比率、總資產週轉率、平均收帳天數及已實現銷貨毛利率。此外,以個案分析危機發生後,存續及未存續兩類公司,藉此探討不同財務危機狀態導致企業面臨能否永續經營的窘境,其原因與舞弊金額、規模,以及涉嫌內線交易或是財報不實程度有其因果關係。[[abstract]]Thisstudywasdrivenbythenumerouscorporatescandalsthatoccurredoverthelastdecade,includingtheEnronandWorldComcasesintheUSandtheProcomp,Rebar,andInfodisccasesinTaiwan,allofwhichhaveseriouslyaffectedtheinterestoftheirinvestors.Therefore,thisstudyattemptedtoanalyzetheclass-actionlitigationcaseshandledbyTheSecuritiesandFuturesInvestorsProtectionCenter(SFIPC)inhopeofidentifyingthecommonformsoffinanciallydistressedcompaniesasafoundationoffinancialcrisiswarning.Therefore,thesampleswerefirmsthatwerepubliclylistedinTaiwanduring2009~2013andwithallthefinancialdatanecessaryforanalysis.ThedatasourcewasthecorporatefinancialdatabaseofTaiwanEconomicJournal(TEJ).Fromtheclass-actionlitigationcaseswonbySFIPC,15companiesinthetechnologyindustrywereselectedtobethesampleoffinanciallydistressedcompanies.Thefinancialdataofthesecompaniesduring2009~2013wereusedformodelingandthenanalyzedusinglogisticregression.Toreinforcethemodelreliability,another15publiclylistedcompanieswereselectedtobethesampleofnormalcompanies.ThesecompanieswereselectedamongTEJ’sTaiwanTop50companiesintheelectronicsindustry,whichwerealsoengagedinthesamebusinessasthefinanciallydistressedcompanies.EmpiricalevidenceshowedthatnomatterintheTaiwanTop50orinindustry-matchedsample,financialstructureandpredictorsofprofitabilityweresignificant,suggestingthatthefocusoffinancialdistresswarningshouldbeplacedonthefinancialstructureandprofitabilityindicesofacompany.Thissuggeststhatinvestorsshouldobservedebtratio,long-termdebttoequityratio,currentratio,quickratio,cashflowadequacyratio,totalassetsturnover,averagecollectionperiodofreceivables,andrealizedgainfromsaleinevaluationofwhetheracompanywillbefacedwithfinancialdistress.Moreover,acaseanalysiswasconductedamongcompaniesthatsurvivedthecrisisandcompaniesthatdidnotsurvivethecrisistoinvestigatewhethercontinuousoperationofacompanyvariesbystatusoffinancialdistress.Resultsindicatedthatthesurvivalofafinanciallydistressedcompanywasrelatedtotheamountinvolvedinthefraud,companysize,thedegreeofstatementfraud,andwhetherthecompanyissuspectedofinsidertrading
