This study examines the risk relevance of recognized versus disclosed finance leases in Japan. In particular, this study investigates whether and why equity investors treat recognized finance lease obligations differently from disclosed finance lease obligations when assessing firms' equity risk. This study shows that recognized finance leases are associated with equity risk but that disclosed finance leases are not. Moreover, the relations between recognized versus disclosed finance leases and equity risk are substantially different. However, for firms with higher levels of institutional ownership, the risk relevance of disclosed finance leases is similar to the risk relevance of recognized finance leases. These results suggest that institutional investors are more sophisticated at processing disclosed finance leases and treating disclosed and recognized finance leases similarly when assessing firms' equity risk. This study provides the evidence that investors' information processing has significant effects on the risk relevance of lease arrangements. This study contributes to the accounting literature on recognition versus disclosure and to the discussions on the global convergence of accounting standards.
