本文以2008年至2015年臺灣之上市(櫃)公司為對象,以托賓Q為衡量公司價值的變數,從股票投資者角度探討企業投保董監事暨重要職員責任保險(簡稱D&O保險)與公司價值之關聯性。實證結果一致地發現,有投保D&O保險之公司,其公司價值較高。此外,實證結果進一步顯示,公司實際投保金額愈高時,公司價值就愈高,但當公司實際投保金額超過正常投保金額(超額投保金額)愈大時,則公司價值卻愈低。
Using publicly available D&O insurance data of the listed firms in Taiwan from 2008 to 2015, this study examines the relationship between directors' and officers' liability insurance (D&O insurance hereafter) and firm value. We use Tobin's Q as a proxy for stock investors' perceptions of firm value. Our empirical results consistently indicate that firms with D&O insurance have higher firm value. Moreover, the results show that D&O insurance coverage is positively associated with firm value. However, if firms purchase excess (abnormal) D&O insurance coverage more than firms' needs, they have lower firm value.
