{"title":"Institutional investors' information needs in the context of the sustainable finance disclosure regulation (EU/2019/2088): the implications for companies' sustainability reporting","authors":"Maria Gebhardt, Anne Schneider, Marcel Seefloth, Henning Zülch","doi":"10.1108/jaar-11-2022-0303","DOIUrl":"https://doi.org/10.1108/jaar-11-2022-0303","url":null,"abstract":"Purpose The paper aims to provide companies with a better understanding of the needs of institutional investors to improve the disclosure of sustainability information by companies. The study investigates the changed information needs of institutional investors resulting from the Sustainable Finance Disclosure Regulation (SFDR). Design/methodology/approach This study uses an internet-based survey instrument amongst institutional investors to gain insights into their needs regarding sustainability information. The authors received 155 responses in total and use descriptive statistics and t -tests to analyse the survey data. Findings The results demonstrate that the implementation of the SFDR challenges institutional investors, as it affects their decision process. Additionally, the findings still indicate a lack of available corporate sustainability information, making it even more challenging for institutional investors to make appropriate investment decisions. Respondents suggest that information on climate-related risks is more important than the European Union (EU) Taxonomy metrics for meeting the SFDR requirements. Research limitations/implications The findings are mainly restricted to the opinion of European investors. However, the evidence contributes to the existing literature by investigating institutional investors' information needs in the new regulatory landscape. Practical implications As the study provides insights into institutional investors' needs, reporting companies recognise the relevance of transparently providing sustainability information to be further considered in the investment process of institutional investors despite the regulation. The findings can help regulators develop uniform and global sustainability reporting standards. Originality/value This paper is the first to provide evidence on sustainability information requested on the institutional investors' side. The survey gathers primary data from professional investment members unavailable in databases or reports.","PeriodicalId":46321,"journal":{"name":"Journal of Applied Accounting Research","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135366159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Differential reporting and earnings quality: is more better?","authors":"Mario Daniele","doi":"10.1108/jaar-08-2022-0206","DOIUrl":"https://doi.org/10.1108/jaar-08-2022-0206","url":null,"abstract":"Purpose When financial statements are public, the choice between alternative reporting regimes constitutes a signal that addresses external stakeholders. Generally, the choice of more complex regimes acts as a complement of firms' transparency. However, in the absence of audits, opportunistic behaviors could be incentivized. This study aims to test whether SMEs' choice between alternative accounting regimes is associated with earnings quality. Design/methodology/approach Drawing on the literature about accounting choices and earnings quality, this study investigates whether the same conclusions are confirmed for SMEs. Using a sample of 4,054 Italian companies and 12,114 observations, it compared four earnings quality proxies of a group of companies that opted for the “Full” rules and those of a subsample of the population of companies that applied the Simplified rules. Findings The results suggest that the signaling power of accounting rules' choice could lead to wrong conclusions for SMEs. Indeed, a positive relationship emerged (H1) between the choice of the “Full” rules and income smoothing behaviors, while the same choice appears to reduce the probability to disclose SPOS. Moreover, the results suggest that opportunistic behaviors are more frequent for firms that have settled in a “non-cooperative” social environment (H2). Research limitations/implications This study could foster research on financial reporting quality in private firms. Practical implications Comparing the quality of financial statements drawn up according to two alternative accounting regimes could provide useful suggestions for both users and regulators. Originality/value The results contribute to the limited literature on the implications of differential reporting. Finally, it enriches the literature about heterogeneity in accounting quality within private firms.","PeriodicalId":46321,"journal":{"name":"Journal of Applied Accounting Research","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135739362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To mitigate any imbalanced distribution effects, entropy balancing techniques are employed.FindingsThe author observes a significant equity market reaction when mandatory adopters adhere to a reporting framework and release sustainability reports as standalone documents. Additionally, the study indicates that government regulation amplifies the equity market reaction for companies that include a board statement within their sustainability reports and present them as standalone publications.Research limitations/implicationsThe lack of quantitative information disclosed in the first-time sustainability reports may restrict the generalizability of the findings.Practical implicationsThe findings provide valuable insights for organizations and managers to evaluate the market's response to sustainability disclosures and improve communication effectiveness with investors. Furthermore, the study has direct policy implications for global standard-setting organizations in sustainability reporting. The findings support the notion that investors value market-led and investor-focused sustainability disclosures.Originality/valueThe study contributes to the limited body of research that examines the capital market effects of mandatory sustainability disclosures.

Specifically, the authors examine how the readability of KAMs is associated with audit partner tenure and workload. Design/methodology/approach The authors conduct the study in the audit context of Norway and applied the Flesch reading ease scale to measure the readability levels of reported KAMs in the audit reports of companies listed on the Oslo Stock Exchange. Panel data estimation techniques are applied in estimating how partner tenure and workload are associated with the readability of KAMs. In addition, several robustness tests including different measures of KAMs readability and subsample analyses are performed. Findings The authors find that audit partner tenure and workload have significant associations with the level of KAMs readability. Specifically, the results show that the reported KAMs become more readable as the audit partner tenure increases but are less readable for partners with more workload. These results appear stronger in subsamples of KAMs typically noted to be more complex and associated with higher risks. Research limitations/implications As KAMs represent the most significant issues in financial statements audit, these results provide important insights to stakeholders on the potential impact of audit partner tenure and workload on KAMs readability. Less readable KAMs could derail stakeholders' desire to bridge the information gap between auditors and users of the audit report. The uniqueness of this study lies in its focus on audit partner characteristics as opposed to the audit firm. Practical implications Excessive audit partner workload impairs KAMs readability.

Design/methodology/approach The sample for this paper consists of 288 financial institutions listed on the Toronto Stock Exchange (TSX) from 2016 to 2019. Panel regressions have been used in this study. Findings The findings reveal that compliance with IFRS 7 is positively associated with the firm's market value. After making a classification between high-compliance and low-compliance companies, the authors' results indicate that the compliance level is positively associated with the value relevance of net income. Surprisingly, when examining the value relevance of financial instruments disclosures (FID) supplied after the adoption of IFRS 9, the authors find that book values of shareholders' equity and earnings are not more value relevant in the post-IFRS 9 period. Research limitations/implications Given that the authors' analysis has been restricted to the Canadian setting, the regression results might not be generalized for other countries with different capital markets features. Practical implications The authors' findings point out that FID can affect investors' decisions as well as their confidence in the companies in which they invest. Hence, the regulatory bodies should gear more efforts to ensure high-compliance levels. Originality/value To the best of the authors' knowledge, this research is among the first attempts to investigate whether the new FID (after the adoption of IFRS 9) improves the firm disclosure quality and enhances the value relevance of accounting information.","PeriodicalId":46321,"journal":{"name":"Journal of Applied Accounting Research","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135199815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Religiosity, financial distress and R&D accounting treatment in US context","authors":"Ines Gharbi, Mounira Hamed-Sidhom, Khaled Hussainey","doi":"10.1108/jaar-12-2022-0322","DOIUrl":"https://doi.org/10.1108/jaar-12-2022-0322","url":null,"abstract":"Purpose Prior research shows that religiosity affects the degree of managers' risk aversion. As a result, religious firms are less likely to invest in R&D activities. Moreover, US GAAP treats these investments as expenses. For this reason, religious firms have fewer expenses in their earnings and are less likely to be in financial distress. Design/methodology/approach Data are collected from Worldscope and the Churches and Church Membership files of the American Religion Data Archive website from 1985 to 2018. With 18,199 observations in US context, the authors used the marginal effect to test the mediating effect of R&D accounting treatment. Findings The authors find that the marginal effect of religiosity on financial distress with US GAAP is higher than the marginal effect of religiosity on financial distress with capitalization of R&D costs, which means that accounting treatment can explain the relation between religiosity and financial distress in the US context. Research limitations/implications The authors used linear interpolation and linear extrapolation data to be able to conduct this research over a period of 1985–2018. For future researches, the authors propose to test other factors which can explain the relationship between religiosity and financial distress based on the ethics element. Practical implications These results should be of interest to regulators because treating R&D activities as expenses can destroy the accounting performance of firms that prefer investing in risky projects. This favoritism prevents the comparison between two firms in the same industry with different risk-taking behaviors. This problem is more prevalent if the authors have two firms with different ratios of religiosity. This paper suffers from a major limitation related to data availability. Originality/value This may be the first study that investigates why religious firms are less likely to be in financial distress. This paper notes that religious firms are less likely to be in financial distress because their conservative behavior towards R&D activities coincides with the conservative R&D accounting treatment. In fact, the mismatch between expenses and revenues from R&D activities can cause financial distress.","PeriodicalId":46321,"journal":{"name":"Journal of Applied Accounting Research","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135387380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The authors present a model for assessing and reporting corporate risk by examining the indicators underlying corporate risk reporting. Design/methodology/approach A thorough review of the literature and semi-structured interviews with experts were conducted and the fuzzy Delphi technique was used to obtain consensus and screening of risks. The relationships between these risk indicators were recognized, weighted and prioritized by employing a hybrid Decision Making Trial and Evaluation Laboratory Model (DEMATEL) method integrated with Analytic Network Process (ANP) (DEMATEL-ANP [DANP]) approach. Finally, using the Iranian setting of corporate risk reporting, a model was developed to calculate the risk-reporting scores. Findings The results indicate that risk disclosure quality is more important than risk disclosures' textual properties and quantity. According to the experts, reporting the key risks that the company faces, management's approach to dealing with these risks and quantifying their impact are more important than the other indicators. The results also show that risk reporting in Iran lacks quantitative and specific information, and most risk disclosures are sticky. Research limitations/implications The data have been prepared and analyzed according to the unique Iranian reporting environment, which should be considered when interpreting the results. Practical implications The results of this research can be used by the regulators of the Stock Exchange Organizations (SEO) to evaluate corporate risk reports and rank companies. Results are also relevant to investors and policymakers to identify companies with poor risk disclosure and to take necessary measures to improve their reporting practices. Social implications This paper contributes to the social and governance literature by presenting the importance of risk reporting in corporate disclosures. Originality/value The unique Iranian setting of corporate risk reporting furthers the understanding of risk reporting and thus provides education, policy, practice and research implications for other emerging economies like Iran. Many prior studies focus mainly on the quality of risk disclosure, and other aspects of corporate risk disclosure presented in the study have remained largely overlooked. The corporate risk reporting attributes identified in the study are relevant to the rise of non-financial risks, the textual and qualitative nature of risk reporting and textual risk disclosures.","PeriodicalId":46321,"journal":{"name":"Journal of Applied Accounting Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134961052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Design/methodology/approach Referring to an agency-theoretical framework, the author differentiates between six categories of ownership (institutional, state, family, foreign, managerial and cross-ownership/ownership concentration). The author also includes research on ownership proxies as moderators of other determinants of tax avoidance. Findings The review indicates that most research refers to institutional, state and family ownership. Moreover, except for state ownership, no clear tendencies on the impact of included ownership types can be found in line with the author’s agency-theoretical framework. Research limitations/implications Regarding research recommendations, among others, the author stresses the urgent need for recognizing heterogeneity within and interactions between ownership proxies. Researchers should also properly address endogeneity concerns by advanced econometric models (e.g. by the difference-in-difference approach). Practical implications As international standard setters have implemented massive reform initiatives on both tax avoidance and corporate governance, this literature review underlines the huge interaction between those topics. Firms should carefully analyze their ownership structure and change their tax planning due to owners' individual tax preferences. Originality/value This analysis makes useful contributions to prior research by focusing on six categories of ownership and their impact on tax avoidance in (multinational) firms and moderating effects.

Nonetheless, the understanding of how AI-based audit services affect this relationship remains sparse. This study strives to probe how an audit client's satisfaction with AI-based audit services influences their trust in audit firms. Identifying the variables affecting this trust, the research aspires to gain a deeper comprehension of the implications of AI-based audit services on the auditor-client relationship, ultimately aiming to boost client satisfaction and cultivate trust.Design/methodology/approachA conceptual framework has been devised, grounded in the client-company relationship model, to delineate the relationship between perceived quality, perceived value, attitude and satisfaction with AI-based audit services and their subsequent impact on trust in audit firms. The research entailed an empirical investigation employing Facebook ads, gathering 288 valid responses for evaluation. The structural equation method, utilized in conjunction with SPSS and Amos statistical applications, verified the reliability and overarching structure of the scales employed to measure these elements. A hybrid multi-analytical technique of structural equation modeling and artificial neural networks (SEM-ANN) was deployed to empirically validate the collated data.FindingsThe research unveiled a significant and positive relationship between perceived value and client satisfaction, trust and attitude towards AI-based audit services, along with the link between perceived quality and client satisfaction. The findings suggest that a favorable attitude and perceived quality of AI-based audit services could enhance satisfaction, subsequently augmenting perceived value and client trust. By focusing on the delivery of superior-quality services that fulfill clients' value expectations, firms may amplify client satisfaction and trust.Research limitations/implicationsFurther inquiries are required to appraise the influence of advanced technology adoption within audit firms on client trust-building mechanisms. Moreover, an understanding of why the impact of perceived quality on perceived value proves ineffectual in the context of audit client trust-building warrants further exploration. In interpreting the findings of this study, one should consider the inherent limitations of the empirical analysis, inclusive of the utilization of Facebook ads as a data-gathering tool.Practical implicationsThe research yielded insightful theoretical and practical implications that can bolster audit clients' trust in audit firms amid technological advancements within the audit landscape.
