研究了资产负债表法（侧重资产和负债估值）如何影响资本充足率在信用评级机构评估银行违约风险中的有用性，发现该法削弱了资本充足率与评级的正相关关系。
This study investigates the association between the balance sheet approach, where financial reporting focuses on asset and liability valuation, and the usefulness of the capital adequacy ratio in the evaluation of bank default risk by credit rating agencies. We examine Japanese banks, which play the central role in the Japanese economy, whose capital adequacy ratios are affected by fair value measurement under the balance sheet approach. We adopt Demerjian’s approach to develop a bank-level measure of balance sheet focus. Although we find a significant positive correlation between the slack of the regulatory capital adequacy ratio and issuer rating, this positive correlation weakens significantly as a bank’s dependence on the balance sheet approach increases. Our results suggest the balance sheet approach makes financial reporting less useful for measuring bank risk.
