Findings show no evidence that firms hold financial derivative instruments exclusively for risk management purposes (e.g. reduction of earnings volatility), indicating a frequent exploitation of the legislative grey zone of derivatives taxation. Ag -gressive tone or the use of weak modals and complex words in firms’ 10-K filings increase firms’ amount of tax avoidance. In case of aggressiveness, the effect of tone is significantly more negative for derivative-using firms.engFinancial derivativesCorporate tax avoidanceHenry sansingTextual analysismaster thesis202793176
