“…A Pearson correlation matrix (untabulated) shows a negative and significant correlation between audit fees and our whistleblower governance proxies ( WBG1 and WBG2 ). The correlations between audit fees and the control variables are found to be consistent with that evident in prior related research (Hay et al ., 2006; Ettredge et al ., 2014; Ittonen et al ., 2019; Mitra et al ., 2019). For instance, we find a negative and significant correlation between AFEE and our control variables ( SIZE , ROA , SECURITEIS , COM_LOAN , CAP_RATIO , NON_AUD_FEE , BIG4 , CEO_TENURE , BD_SIZE , BD_IND , AUD_IND and RISK_IND ).…”
