The impact of opacity on bank valuation during the global financial crisis: A channel analysis

Prior literature suggests that opacity in the banking industry is mainly caused by a lack of informativeness in the assessment of the quality of bank assets. Examining a sample of bank holding companies in the United States, we find that there is a negative relationship between opacity and bank valuation during the 2007–2009 global financial crisis. We further attempt to identify two potential channels through which opacity negatively affects bank valuation during the financial crisis: a cash flow channel and an expected return channel. We show that one channel flows from bank profitability, measured by return on equity and return on assets, confirming a cash flow channel, whereas an expected return channel, proxied by the implied cost of capital, only works for small banks. Overall, this study sheds light on the relationship between in-transparency and bank value discount during a global recession.

Investment opportunities and cash holdings of firms: an empirical study on Korean firms

We find that the cash flow sensitivity of cash holdings of firms whose investment opportunities are lower is significantly higher by examining a panel data of 898 Korean firms for 1999–2014. The cash flow sensitivity of investment is also found to be lower in case of low investment opportunity. Both findings suggest that firms decide to hold cash in response to an increase in cash flow when they do not have a good investment opportunity. Precautionary motive because of financial constraints and uncertainty, and agency problems, however, are not associated with the cash flow sensitivity of cash holdings. These findings imply that it is necessary to develop new investment opportunities to encourage firms to spend more cash in Korea.     

"净利+利息+折旧"抑或"净利+税后利息+折旧"?——对会计资格考试辅导教材中经营现金净流量计量方法的商榷

计算项目净现值(NPV)等投资决策指标时,现金流量与折现率应具有匹配关系。从两者的匹配关系看,全国会计专业技术资格考试辅导教材《财务管理》一书中的经营现金净流量(NCF)计量公式有欠妥当。因为以项目的加权平均资本成本(WACC)作为折现率时,与之相应的NCF的计量方法不应是教材中的“净利 利息 折旧”,而应该是“净利 税后利息 折旧”,或者是“息税前利润(1-所得税率) 折旧”。     

Camouflaged Indicators of Earnings Management†

Abstract

We argue that, in response to increased scrutiny and greater attention to accruals versus sales, firms become more likely to engage in accrual conversion (AC) cash management aimed at aligning cash and accruals with earnings and sales (e.g. by factoring of receivables). In doing so, they reduce the statistical power of standard indicators of accrual-based earnings management – in effect, camouflaging their earnings management activity. This proposition is of interest because many influential papers on earnings management have utilized accrual-based indicators to reach their conclusions. Our results indicate that firms indeed became more likely to engage in AC cash management after the passage of the Sarbanes-Oxley Act (SOX), and that this tendency was particularly pronounced among firms with strong incentives (or enhanced ability) to perform and hide earnings management. In particular, our findings suggest that the post-SOX decrease in standard measurements of accrual-based earnings management, identified in prior research, is partially attributable to firms’ increased engagement in AC cash management activity.
