Abstract:
We show, analytically and empirically, that there is a positive correlation between default risk and the Basu measure of conservatism: the higher the default risk, the higher the bias in the Basu measure. We use the insight provided by our analysis to construct an improved version of the Basu measure, the Default-Adjusted-Basu (DAB) measure. The DAB measure adjusts for the effects of default risk on the Basu measure. Using Distance-to-Default as a measure of default risk, we contend that the DAB measure can substantially reduce the bias caused by default risk, and hence is a more robust measure of accounting conservatism than the standard Basu measure. We demonstrate that once one adjusts for the distance-to-default, the Basu conservatism coefficient is no longer positively correlated with leverage.
