Corporate Governance and Firm Performance in Iran

This study uses data from companies listed in the Tehran Stock Exchange (TSE) for the years 2005–2006 to investigate the role of corporate governance indices on firm performance. We use board size, board independence, board leadership and institutional investors on the board as corporate governance indices and EPS, ROA and ROE as firm performance surrogates. Our regression results show that board size is negatively associated with firm performance. Moreover, the presence of outside directors strengthens the firms' performance. We find, however, no relationship between leadership structure and firm performance. Likewise, the presence of institutional investors on the board of directors is not positively associated with firm performance.     

Decision usefulness of whole-asset operating lease capitalizations

Monson (2001) and Hepp and Scoles (2012) argue that some leased assets should be capitalized at the assets' purchase price (whole-asset value) rather than at the present value of future minimum lease payments (right-of-use asset value). The argument is based in part on the notion that the assets under lease generate future income not the obligation related to future lease payments. To test the notion we compare associations between capitalizations representing whole asset values and current and future return on assets (ROA) and return on equity (ROE) with capitalizations representing right-of-use asset values and current and future ROA and ROE. Our results indicate that the whole-asset annuity values are incrementally associated with future ROA and ROE over right-of-use asset values. We interpret our results to suggest that the current practice of capitalizing future lease payments does not fully reflect the income generation provided by leased assets.     

Performance choice,executive bonuses and corporate leverage

This study examines the causal link between a firm's leverage decisions and the characteristics of its CEO bonus plans. Results from a simultaneous equations model strongly suggest that highly levered firms are less likely to use return on equity (ROE) or ROE-based accounting performance measures to determine executive bonuses. Estimates also indicate that firms with fewer debt covenants, higher interest rates on debt, and a greater proportion of executive pay in the form of stock options are less likely to adopt ROE-based measures for use in CEO bonus plans. These findings lend strong support to the efficient contracting hypothesis. The conflicting interests of corporate stakeholders, especially between stockholders and creditors, encourage firms to tie executive pay to performance metrics like return on assets (ROA) that will strike the optimal balance between the agency costs of debt and the agency costs of equity.Data availability: all data are available from public sources.     

EVA, ACCOUNTING PROFITS, AND CEO TURNOVER: AN EMPIRICAL EXAMINATION, 1985–1994

A growing number of companies use EVA or related measures of economic profits as metrics for corporate planning and executive compensation. Unlike traditional accounting measures of performance, EVA attempts to measure the value that firms create or destroy by subtracting a capital charge from the cash returns they generate on invested capital. For this reason, EVA is seen by its proponents as providing the most reliable year-to-year indicator of a market based performance measure known as market value added, or MVA. Although EVA and MVA have received considerable attention in recent years, there has been little empirical study of these performance measures—and what studies have been produced have provided mixed results. This study joins the debate over EVA vs. conventional accounting measures by asking a different question: Which performance measures do the best job of explaining not only stock returns, but the probability that a CEO will be dismissed for poor performance? Using a sample of 452 firms during the period 1985–1994, the authors report that EVA has a somewhat stronger correlation with stock price performance than conventional accounting measures such as ROE and ROA. But, of greater import, EVA appears to be a considerably more reliable indicator of CEO turnover than conventional accounting measures.     

中国寿险公司多元化经营的风险分析

选取新华、国寿、太平、泰康、平安等五家寿险集团公司从2001~2011年每年绩效指标中总资产收益率和净资产收益率的标准差作为度量公司风险的指标,将五家公司的业务线熵指数的均值作为多元化经营的指标进行实证分析。结果表明:多元化经营与寿险公司总资产收益率、净资产收益率的标准差之间存在一定的非线性关系,即多元化经营在一定范围内可以降低ROA和ROE的波动性,但在一定范围内又可能会增大这种波动性。     

La eficiencia técnica de los bancos durante la crisis Caso aplicado a la rentabilidad de la banca comercial en México y Chile

This paper aims to determine evidence about the efficiency of commercial banks under crisis periods when compared against their regular operating periods. Particularly, the Chilean and Mexican banking industries are reviewed by an innovated Data Envelopment Analysis (DEA) methodology. Conclusive evidence of an increase in efficiency for the incumbent banks under crisis periods is presented, as measured by their Return on Assets (ROA) and Return on Equity (ROE). Finally, evidence is found showing that when considering the banks that are more efficient during the whole period of analysis, their better performance is focused during the crisis periods, measured by their ROA and ROE as performance indexes. In most cases, banks that were more efficient during the previous-to-crisis period, had a lower performance during the crisis periods.     

Reclassification of Financial Assets under IAS 39: Impact on European Banks' Financial Statements

In response to the financial crisis, the IASB issued on 13 October 2008 an amendment to IAS 39 which enables entities to reclassify non-derivative financial assets held for trading and financial assets available-for-sale. This paper examines the influence of this controversial amendment on the 2008 financial statements of 219 European banks which apply IFRS. I find that approximately one-third of the sample banks have taken extensive advantage of these reclassification opportunities. The mean reclassification amount is 3.9% of total assets and 131% of the book value of equity, respectively. I further document that reclassifying banks avoid substantial fair value losses, and hence, report significantly higher levels of return on assets (ROA), return on equity (ROE), book value of equity and regulatory capital. In particular, the mean ROE switches sign from a negative ROE of ?1.4% to a positive ROE of 1.3% due to gains from reclassifications. Overall, this paper documents a substantial impact of the amendments on banks' financial statements and suggests analysing these reclassifications with particular caution.     

Do institutional shareholder services (ISS) corporate governance ratings reflect a company's operating performance?

Little is known about the relation between the actual governance rating received by a firm and the firm's performance. In this study, we examine the relation between the actual corporate governance rating received by a firm and the firm's performance during the years 2002–2004. We use the institutional shareholder services (ISS) corporate governance quotient (CGQ) rating of a firm's corporate governance structure and analyze this rating in relation to the firm's operating performance. We compare the institutional shareholder services’ CGQ rating to two measures of the firm's operating performance, return on assets (ROA) and return on equity (ROE). Based upon our results, we do not find statistical evidence suggesting that the firms’ operating performance is related to the firms’ ISS corporate governance rating.     

A Tale of Leadership in Value Creation

In this prologue to his new book, Curing Corporate Short‐Termism, the founder and CEO of Fortuna Advisors presents a fictional account of a corporate turnaround—a “composite” reflection of the author's many years of consulting experience that dramatizes the pressure to meet near‐term earnings targets and other kinds of “agency” problems facing a public company called Blue Dynamics Corp. The tale begins with the puzzlement of the incoming CEO, Betty Manning, at finding the company's highest‐return business unit starved for investment, even as the low‐return units continue to receive and spend capital with little success. At the core of the company's capital allocation and “underinvestment” problems, she finds a corporate‐wide performance measurement and reward system focused on setting and beating budgets and growth in EPS and ROE. Manning's solution is to divorce the performance and reward system entirely from the budgeting process and implement new annual incentives and target‐setting practices that result in both more reliable budgeting and forecasting and a longer‐term view of value creation. The new measure of economic profit, called BDVA (short for Blue Dynamics Value Added), is based on a customized measure of EBITDA less a capital charge. The adoption of the new measure has the effect of encouraging her team to take a number of decisive steps: make an objective, “fact‐based” case for a strategic acquisition whose price appears to be too high (at least using conventional measures like EPS accretion); pull the trigger on a divestment that appears to have been adding value, but is more valuable outside the firm; and, more generally and most important, guide operating managers toward an ideal balance of overall growth and return on capital.     

高层管理当局薪酬与上市公司业绩的相关性实证研究

本文在对国内外文献进行综评的基础上,立足于中国资本市场的特殊制度背景,分别选择会计绩效指标(ROA、ROE)、市场指标(Tobinq)以及股东财富指标(OF)构建模型,对我国上市公司高层管理当局的薪酬激励、特别是现金薪酬与上市公司业绩之间的相关性进行了经验研究,并减弱了相关的多重共线性现象。我们发现,高层管理当局薪酬与公司以及股东财富前后两期的变化,均成正相关关系;而与本期Tobinq的变化成负相关关系,与上期Tobinq的变化成正相关关系。公司的董事会或薪酬委员会在决定高层管理当局薪酬时青睐于会计盈余指标的变化更甚于信任股东财富指标。     

Gender-diverse board and the relevance of voluntary CSR reporting

In this paper, we focus on voluntary corporate social responsibility (CSR) disclosure, and we test the extent to which the value relevance of CSR reporting is affected by the appointment of female directors. Using a sample of French listed companies belonging to the SBF 120 index from 2001 to 2011, we control for differences in firm characteristics between firms with and without female board membership by using propensity score matching. Our results show that high CSR reporting is more relevant in terms of market value for firms with gender-diverse boards than for firms with completely male directors. This finding holds when we use the accounting-based performance measures, namely, return on assets (ROA) and return on equity (ROE). We also highlight that engaging an external assurance provider for CSR reporting is value relevant for firms without female directors but not value relevant for firms with female directors, suggesting a substitute relationship between gender-diverse boards and CSR assurance. Our results are stable when we consider the presence of at least two and three female directors.     

Prospect theory and the risk-return paradox: some recent evidence

There is extensive evidence indicating a negative risk–return relation when a firm’s performance is measured based on accounting measures such as return on asset (ROA) and return on equity (ROE). Previous studies show that the risk-return paradox can be explained by the prospect theory, which predicts that managers’ risk attitudes are different for firms of different performances. However, those studies mostly use earlier data from the COMPUSTAT database, which suffers from a survivorship bias. Failure to account for delisting firms may understate the risk–return relation. We reexamine the mixture of risk-seeking and risk-averse behaviors based on an updated 20-year sample period that is free from the survivorship problem. Interestingly, our results show stronger and robust evidence supporting the prospect theory during the period from 1984 to 2003.     

Accounting‐Based Probabilistic Prediction of ROE,the Residual Income Valuation Model and the Assessment of Mispricing in the Swedish Stock Market

Using Swedish stock market data, this study investigates whether an investment strategy based on publicly available accounting information can generate abnormal investment returns. The strategy involves two steps. First, an accounting‐based probabilistic prediction model of changes in the medium‐term book return on owners' equity (ROE) is estimated. Second, market expectations of changes in medium‐term ROE are assessed through observed stock prices and the residual income valuation model. Stock market positions over 36‐month holding periods are taken when the accounting‐based predictions of ROE and the market expectations differ. Over the period 1983–2003, the investment strategy generated values of Jensen's alpha corresponding to an average monthly excess return for a hedge position of up to 0.8% for a sample of manufacturing companies. In the main this hedge return was caused by strong positive returns to the long positions, and additional analyses show that the returns appear to have been affected by a positive market sentiment bias (i.e., positive ROE surprises being associated with stronger price reactions than negative ROE surprises) making out‐of‐sample inferences somewhat dubious. Furthermore, most of the investment returns accrued over holding periods up to around 1995, with no indications of market mispricing over the last third (1995–2003) of the investment period. The empirical results are consistent with market investors having become more sophisticated in their use of publicly available accounting information over time.     

Liquidity management,operating performance,and corporate value: evidence from Japan and Taiwan

This study examines the relationship between liquidity management and operating performance, and that between liquidity management and corporate value for firms in Japan and Taiwan. We observe that the cash conversion cycle (CCC)–returns on assets (ROA) and CCC–returns on equity (ROE) relationships are commonly negative and sensitive to industry factors. Both Japanese and Taiwanese firms with q>1 have significantly lower CCC than firms with q⩽1. In addition, Japanese firms with q>1 have significantly higher ROA and ROE than firms with q⩽1. Overall, the findings indicate that aggressive liquidity management enhances operating performance and is usually associated with higher corporate values for both countries in spite of differences in structural characteristics or in financial system of a firm.     

Do ESOPs enhance firm performance? Evidence from China’s reform experiment

China introduced employee stock ownership plans (ESOPs) in 1992 purely as an employee incentive scheme. The government initiated the policy experiment on ESOPs as part of China’s reform of its state-owned enterprises, and it was abruptly terminated 2 years after initiation. This policy experiment resulted in an exogenous sample of ESOPs that allows us to provide the first evidence from Chinese firms on the performance-ESOP relation. After examining a variety of performance measures, including ROA, ROE, Tobin’s q, and productivity, we find little difference in performance between ESOP firms and non-ESOP firms.     

Mergers &; Acquisitions,Diversification and Performance in the U.S. Property-Liability Insurance Industry

This paper examines the relationship between mergers & acquisitions (M & As), diversification and financial performance in the U.S. property-liability insurance industry over the period 1989–2004. The risk-adjusted return on assets (ROA), return on equity (ROE), Z-score and total risk measured by earnings volatility are considered as a relevant indicator of performance. We find that acquirers’ financial performance decreases and earnings volatility increases during the gestation period after the M & As perhaps due to increased frictional costs associated with post-merger integration and agency problems. We find that more focused insurers outperform the product-diversified insurers, implying that the costs of diversification outweigh the benefits. These findings are robust to alternative risk and diversification measures. We also find that marginal increases in commercial line share are associated with higher risk-adjusted profits, but these gains are offset by the extra costs from product diversity when its initial share is low. For insurers initially concentrated in commercial line, a marginal increase in commercial line share is related to higher performance due to positive effects of both direct exposure and indirect focus.     

Governance through trading on acquisitions of public firms

We identify an important channel, acquisitions of public targets, via which the governance through trading (GTT) improves firm values. The disciplinary effect of GTT is more pronounced for firms with higher managerial wealth-performance sensitivity and moderate institutional ownership concentration. Firms with higher GTT also have higher subsequent ROA, ROE, Tobin's Q, analysts forecasted EPS growth rate, and lower expected default risk. The effect is stronger after Decimalization. We conduct several exercises to rule out alternative explanations, such as institutional superior information, investor activism, and momentum. Additional tests show that the disciplinary effect of GTT only exists for less financially-constrained firms and non-all-cash M&As where the agency problem is more likely to be prevalent.     

The relationship between net interest margin and noninterest income using a system estimation approach

This paper examines the determinants of bank net interest margin (NIM) and non-traditional banking activities (NII). A system estimation approach is employed to control for the simultaneity between NIM and NII for commercial banks in a group of 28 financially liberalized countries during the period between 1997 and 2004. We find a statistically significant negative relationship between NIM and NII for the period between 1997 and 2002. A generally positive but statistically insignificant association between NIM and NII is found for the subsequent period (2003–2004). Banks’ increasing involvement in non-traditional activities is negatively correlated with risk-adjusted profitability measures in the former subperiod, suggesting no obvious diversification benefits. However, the share of noninterest income is positively related to the return on assets (ROA) and the return on equity (ROE) for the latter subsample.     

The choice between rights and underwritten equity offerings: Evidence from Chinese stock markets

We study the choice and valuation effects of alternative flotation methods using a sample of Chinese firms that must meet the return on equity (ROE) thresholds set by the government to raise equity capital. The ROE requirement, although changed over time, seems to play an important role on the valuation and performance of seasoned equity offerings. The analysis of 219 rights and 75 underwritten offerings between 2000 and 2004 shows that Chinese firms that are not qualified for the flotation method with a higher ROE requirement suffer the most at announcement and experience significantly lower buy-and-hold abnormal returns than those that are qualified. Our results suggest that the freedom to choose their preferred flotation method may be valuable to firms that meet the higher ROE requirement. Finally, our probit models identify several determinants of the choice of flotation methods.
