This study examines whether the adjustment of earnings based on constant currency basis (hereinafter referred to as constant currency reporting) affects stock price crash risk and foreign exchange exposure coefficients of U.S. listed firms. Prior literature shows that constant currency reporting makes investors better recognize the operational performance of firms. However, some studies indicate that managers would strategically disclose constant currency reporting to mislead investors. Little research analyzes the association between constant currency reporting and firm risk. Therefore, this study examines the impact of constant currency reporting on stock price crash risk and foreign exchange exposure coefficients. The association between constant currency reporting and foreign exchange exposure is not significant; however, firms adopting a combination of constant currency reporting and operational hedging strategies could significantly reduce exposure to Major Currency Index. The results also show a negative association between constant currency reporting and stock price crash risk, implying that the disclosure of constant currency reporting provides valuable information and allows investors to estimate stock price more accurately. Nevertheless, when facing US dollar appreciation or foreign exchange loss, U.S. firms tend to have higher crash risk after disclosing constant currency reporting, suggesting the disclosure is motivated by opportunism when exchange rate fluctuations are unfavorable to firms.參考文獻 顧子宜(2023),影響美國公司以固定匯率評估財報的因素,國立政治大學財務管理學系碩士學位論文。 Adler, M., & Dumas, B.
