Do Accruals Earnings Management Constraints and Intellectual Capital Efficiency Trigger Asymmetric Cost Behaviour? Evidence from Australia

This study examines whether accruals earnings management constraints and intellectual capital (IC) efficiency affect asymmetric cost behaviour by analysing data for the 1990 to 2016 period on firms listed on the Australian Securities Exchange. The analysis reveals that, on average, anti‐sticky cost behaviour occurs when firms have limited ability to engage in accrual earnings management to manipulate earnings in the current year. Further, IC efficiency – particularly human capital efficiency – increases the degree of cost stickiness. This study also finds that the degree of asymmetric cost behaviour is more pronounced in the post‐International Financial Reporting Standards (IFRS) period than in the pre‐IFRS period. The results suggest that the increased asymmetric cost behaviour in the post‐IFRS period derives from higher IC efficiency relative to the pre‐IFRS period. This study presents important implications for external stakeholders because they can consider the extent of earnings management constraints and the extent of firms’ IC efficiency as the determinants of asymmetric cost behaviour when assessing firms’ cost behaviour.     

Do Restatements Improve the Persistence of Earnings and Its Components?

We examine the persistence of earnings in the pre‐ and postrestatements periods and find that restatements generally improve the persistence of earnings. We also examine how the persistence of earnings is influenced by restatements that are voluntarily initiated by managers (voluntary restatements) and those forced onto firms by outsiders (mandated restatements). Our analysis shows that voluntary restatements are followed by improvement in the persistence of earnings and that mandated restatements are not followed by improvement in earnings persistence. We find results that are consistent with the main finding when we decompose earnings into accruals and free cash flows. We use a difference‐in‐difference research design and confirm that the improvement in the postrestatement persistence of earnings components exceeds that of control firms only for voluntary restatements. Further, we show that our results are robust after controlling for endogeneity of voluntary restatements by including a two‐stage model using the Heckman ( 1979 ) method where we first estimate the likelihood of manipulation detection and analyze change in persistence conditional on the first stage analysis. The improvement in earnings persistence around voluntary restatements is not driven by the level of earnings decomposition or a subgroup of voluntary restatements. The results support our hypothesis that voluntary restatements have distinctly different economic consequences from mandated restatements.     

Quality of reported earnings by Chinese firms: The influence of ownership structure

This paper examines the influence of ownership structure on earnings quality of firms listed on the Chinese Stock Exchanges. We empirically test four contemporary earnings quality measures, including volatility of earnings, variability of earnings over cash flows, correlations between accruals and cash flows, and level of discretionary accruals, for 1438 firms listed on Shenzhen Stock Exchange and Shanghai Stock Exchange. We find that although state-owned firms are bigger in size and appear more profitable based on reported earnings; privately-owned firms, foreign-owned firms and society-owned firms outperform the state-controlled firms in earnings quality; and foreign-owned firms have the highest earnings quality among all types of ownership groups. We find that there is not much difference in earnings quality between collectively-owned firms and state-owned firms and employee-owned firms exercise least discretion in earnings management. The findings in particular will have direct policy implications for the China Securities Regulatory Committee (CSRC).     

The Israeli XBRL Adoption Experience

eXtensible Business Reporting Language (XBRL) is a language for the electronic communication of business and financial data which is revolutionizing business reporting around the world. It is a tool to bridge potential language barriers and unify financial reporting. This has appeal to foreign investors, among others, who can rely on information in XBRL‐tagged financial reports to make investment decisions without having to translate financial statements from local language. In 2008, Israel required most public companies to adopt International Financial Reporting Standards (IFRS) for financial reporting and to use XBRL‐tagged reporting format, as part of an aggressive effort to make its capital markets more transparent and attractive for foreign investors. In this paper, we study all Israeli public companies and analyze the accuracy and reliability of their XBRL‐tagged financial statements that are available on MAGNA, the Israel Securities Authority's electronic system. We describe the process by which the XBRL‐based data were collected and reported. We document, categorize, and analyze deficiencies in the XBRL‐tagged filings, and inconsistencies between them and the Hebrew‐based annual reports. We observe pervasive data entry errors resulting in inaccurate XBRL‐generated financial reports, which went undetected for over one year. Further, first year XBRL reporting (in conjunction with IFRS adoption) did not increase foreign investment in the Israeli capital markets. This analysis allows us to better understand the benefits and challenges of the adoption of XBRL.

Accounting Standards and Earnings Management: Evidence from China

This article examines the effect of an asset impairment–related regulatory reform on earnings management in China. Chinese Accounting Standard No. 8 (CAS No. 8), which prohibits the reversal of long‐lived asset impairments, was promulgated to constrain managerial opportunism with respect to previously recognized impairment loss reversal. CAS No. 8 forbids the reversal of long‐lived asset impairment losses only, while allowing the reversal of short‐term asset impairment losses. Based on a sample of China's A‐share listed companies on the Shanghai and Shenzhen Stock Exchange during the period 2001–2008, we reveal that managers use less current asset write‐downs and more reversals in the post–CAS No. 8 period. However, such reporting practices do not appear to be influenced by managerial incentives to avoid reporting losses and/or for “big bath” accounting purposes.     

Earnings Management and Firm Performance Following Open-Market Repurchases

Both post‐repurchase abnormal returns and reported improvement in operating performance are driven, at least in part, by pre‐repurchase downward earnings management rather than genuine growth in profitability. The downward earnings management increases with both the percentage of the company that managers repurchase and CEO ownership. Pre‐repurchase abnormal accruals are also negatively associated with future performance, with the association driven mainly by those firms that report the largest income‐decreasing abnormal accruals. The study suggests that one reason firms experience post‐repurchase abnormal returns is that post‐repurchase realized earnings growth exceeds expectations formed on the basis of pre‐repurchase deflated earnings numbers.     

Information processing costs and corporate tax avoidance: Evidence from the SEC’s XBRL mandate

The IRS uses information contained in financial statements as well as tax returns to detect tax avoidance behavior. We examine the impact on corporate tax avoidance behavior of reductions in the IRS’s information processing costs resulting from the mandatory adoption of XBRL for financial reporting. Motivated by the recent debate in the U.S. Congress over the cost-benefit of mandatory XBRL reporting for small firms, we pay particular attention to small firms, which inherently have relatively high information frictions. We find that the adoption of XBRL for financial reporting results in a significant decrease in tax avoidance. We further find that the negative relation between XBRL reporting and tax avoidance is less prominent for firms subject to more intense IRS monitoring in the pre-XBRL-reporting period. Overall, our results suggest that XBRL reporting reduces the cost of IRS monitoring in terms of information processing, which dampens managerial incentives to engage in tax avoidance behavior.     

Impact of IFRS in New Zealand on Accounts and Earnings Quality

The impact of the adoption of International Financial Reporting Standards (IFRS) on the accounts and the quality of earnings of New Zealand firms is examined. Our analysis of IFRS adjustments for the last period under pre‐IFRS NZ Generally Accepted Accounting Principles (GAAP) reveals that total assets, total liabilities and net profit were significantly higher under IFRS than under pre‐IFRS GAAP. Profit and equity under IFRS were increased by adjustments for goodwill and other intangibles and investment property, and decreased by adjustments for employee benefits and share‐based payments. Using data for 2002–2009, we find that absolute discretionary accruals were significantly higher under IFRS than under pre‐IFRS NZ GAAP, suggesting lower earnings quality under IFRS than under pre‐IFRS NZ GAAP. However, we find no significant differences in signed discretionary accruals and the ability of earnings to predict one‐year‐ahead cash flows between pre‐IFRS NZ GAAP and IFRS. These results are consistent across alternative measures of accruals quality, sample selection and whether firms elected to adopt IFRS in 2005 rather than comply with them in 2007.     

XBRL adoption and expected crash risk

The U.S. Securities and Exchange Commission (SEC) mandated the adoption of eXtensible Business Reporting Language (XBRL) in 2009, with the aim of facilitating data exchange and reducing information processing costs. To shed light on the economic consequences of this important disclosure regulation, this study investigates whether and how XBRL mandate impacts investor expectations of future crash risk. Using the steepness of the option implied volatility smirk as a proxy for ex ante expectation of crash risk, we find that expected crash risk decreases after adoption of XBRL. Moreover, we document that the effect is more pronounced for firms with higher financial opacity, more volatile earnings, and greater analyst forecast dispersion. Further, our analysis generates evidence that the use of customized extension XBRL elements attenuates the effect of XBRL reporting on reducing expected crash risk. Our empirical results are robust to a variety of sensitivity checks. Overall, the findings indicate that XBRL reduces information processing costs and strengthens information transparency of capital markets, which in turn, reduces investor expectations of future crash risk.     

The Operating Performance of Firms that Switch Their Stock Listings

In this article we examine the operating performance of stocks that switch from NASDAQ to the American Stock Exchange (AMEX) or the New Stock Exchange (NYSE) and from AMEX to the NYSE. Specifically, we investigate whether post‐listing operating performance is consistent with the reported negative long‐term drift of post‐listing stock returns and whether there is evidence of self‐selection of the listing time. We find evidence of negative post‐listing changes in operating return on assets and sales, which, on a match‐adjusted basis, are significant for the relatively small NASDAQ stocks switching to AMEX. We also find evidence that firms self‐select the time of listing changes.     

The Efficacy of Regulation Fair Disclosure

This paper examines the impact of Securities and Exchange Commission's Regulation Fair Disclosure (FD) on information leakage around voluntary management disclosures. We find a positive correlation between stock returns two days before and after the voluntary disclosure in the pre‐Regulation FD period, but not in the post‐Regulation FD period. After Regulation FD is implemented, pre‐announcement abnormal return as a percentage of total return decreases by 26.1% (21.4%) for large firms with good (bad) news, suggesting that the amount of information leakage reduces for these firms. These findings provide support for the premise and the intended purpose of the regulation for large firms.     

Does the monitoring role of buyout houses improve discretionary accruals quality?

Using a sample of reverse leveraged buyout (‘reverse‐LBO’) firms, I find that discretionary accruals quality (AQ), the quality of accruals that are subject to management discretion, significantly improves from pre‐LBO to post‐reverse LBO. Moreover, buyout houses’ board seats and the length of firms’ stay‐in‐private periods are significant explanatory variables for the cross‐sectional variation in discretionary AQ for post‐reverse‐LBO firms. My findings suggest that the monitoring provided by private equity buyout houses improves discretionary AQ, consistent with the view of Jensen (1989a,b) that LBOs are a solution to inefficiencies that arise from agency problems.     

Does market misvaluation help explain share market long‐run underperformance following a seasoned equity issue?

We examine the relation between pre‐seasoned equity offering (SEO) announcement date misvaluation and long‐run post‐SEO performance for a large sample of Australian SEOs made between 1993 and 2001. Our study is motivated by inconsistent findings across countries with respect to the SEO long‐run underperformance anomaly first documented in the USA, inconclusive findings with respect to the hypothesis that managers exploit market misvaluation when timing equity issues, and a recent Australian Stock Exchange proposal to loosen SEO regulation. We find SEO firms underperform common share market benchmarks for up to 5 years after the announcement. Using a residual income valuation method, we show that this underperformance is related to pre‐announcement date misvaluation. An unexpected result is that underperformance and misvaluation are more severe for private placements than rights issues. Institutional factors unique to the Australian setting, particularly the large number of smaller loss‐making firms among private placement issuers, appear to explain the poorer performance of placement firms. Our results are robust to various measurement methods and assumptions, and demonstrate the importance of researching SEO performance in alternative institutional settings.     

Big Six auditors and audit quality: The Korean evidence

This study investigates the association between discretionary accruals and Big Six and non-Big Six auditors, and the direction of auditor change. We hypothesize that there is no significant difference in discretionary accruals between Big Six and non-Big Six clients when there is low incentive for auditors to provide high-quality audits, as in Korea.Upon examination of the discretionary accruals of firms listed on the Korean Stock Exchange from 1994 to 1998, we find there is no significant difference between the discretionary accruals of firms with Big Six and non-Big Six auditors. This holds true for firms that switch from non-Big Six to Big Six auditors and vice versa. These resources imply that there may be no difference in audit quality between Big Six and non-Big Six auditors in Korea. This is consistent with other studies in Korea, while inconsistent with the findings of previous studies on audit quality in other countries.     

Segment Reporting Practices in Australia: Has IFRS 8 Made a Difference?

This study examines changes in segment reporting in Australia following the adoption of the international accounting standard, IFRS 8 Operating Segments. We analyse segment disclosures of the top 200 companies listed on the Australian Stock Exchange in their pre‐ and post‐adoption of AASB 8, the equivalent Australian standard to IFRS 8. Our findings indicate that the number of reportable segments and the extent of disclosure have increased post‐adoption of AASB 8. Contrary to expectations, however, there is very little change in the identification of reportable segments. Companies, in general, have managed to retain their segment reporting formats and disclosures from the pre‐AASB 8 period.     

Executive Turnover,Gender, And Earnings Management: An Exploratory Analysis

This paper examines the relationship between the Chief Financial Officer (CFO) turnover and earnings management. Based on cross‐sectional panel regressions on a three‐year sample of the Standard & Poor's (S&P) 1500 firms, the following findings are reported: (1) CFO turnover is accompanied by income‐decreasing earnings management; (2) discretionary accruals tend to become more negative when a male CFO is replaced by a female; (3) earnings management increases income if the outgoing CFO is a female and the incoming is a male and in the case of male–male CFO changes. Overall, these results indicate that the firms who hire a female CFO after a male tend to shift toward more conservative financial reporting practices.     

The Impact of Information Processing Costs on Firm Disclosure Choice: Evidence from the XBRL Mandate

This paper examines the effect of market participants’ information processing costs on firms’ disclosure choice. Using the recent eXtensible Business Reporting Language (XBRL) regulation, I find that firms increase their quantitative footnote disclosures upon implementation of XBRL detailed tagging requirements designed to reduce information users’ processing costs. These results hold in a difference‐in‐difference design using matched nonadopting firms as controls, as well as two additional identification strategies. Examination of the disclosure increase by footnote type suggests that both regulatory and nonregulatory market participants play a role in monitoring firm disclosures. Overall, these findings suggest that the processing costs of market participants can be significant enough to impact firms’ disclosure decisions.     

Earnings Quality Measures and Excess Returns

This paper examines how commonly used earnings quality measures fulfill a key objective of financial reporting, i.e., improving decision usefulness for investors. We propose a stock‐price‐based measure for assessing the quality of earnings quality measures. We predict that firms with higher earnings quality will be less mispriced than other firms. Mispricing is measured by the difference of the mean absolute excess returns of portfolios formed on high and low values of a measure. We examine persistence, predictability, two measures of smoothness, abnormal accruals, accruals quality, earnings response coefficient and value relevance. For a large sample of US non‐financial firms over the period 1988–2007, we show that all measures except for smoothness are negatively associated with absolute excess returns, suggesting that smoothness is generally a favorable attribute of earnings. Accruals measures generate the largest spread in absolute excess returns, followed by smoothness and market‐based measures. These results lend support to the widespread use of accruals measures as overall measures of earnings quality in the literature.
