To investigate, compare and document the magnitude and extent of intellectual capital disclosure to sustainability disclosure during a transition from a voluntary to mandated “comply or explain” sustainability reporting regime. And to empirically test if, during the regime transition period, changes in the magnitude (extent) of sustainability disclosure is a significant determinant of changes in the magnitude (extent) of intellectual capital disclosure.

Content analysis of 1,744 annual reports drawn from 436 Singapore listed firms spanning a four-year observation window (i.e. April 1, 2014 to March 31, 2018). The magnitude (number of sentences) and extent (number of items) of (1) intellectual capital disclosure measured using a 38-item index; (2) sustainability disclosure of a 105-item index; and (3) 15-item index to measure the magnitude and extent of joint sustainability/intellectual capital disclosure.

The average magnitude and extent of sustainability and the joint sustainability/intellectual capital disclosure increased whilst the average magnitude and extent of intellectual capital disclosure increased when regulatory discussion of a change to mandated sustainability reporting emerged. However, in the annual period the mandated sustainability reporting became effective while the average magnitude and extent of intellectual capital disclosure declined. Regression tests indicate a significant (insignificant) association between the change in the magnitude (extent) of sustainability disclosure and intellectual capital disclosure.

From a research perspective, the analysis implies researchers investigating the consequences of mandated sustainability disclosure should consider impact on alternative non-financial disclosure themes and develop theoretical frameworks to derive why and how management may shift non-financial reporting strategies and practices.

For regulators, findings suggest there may be a need to weigh spillover costs of reductions in transparency related to intellectual capital. For investors, declines in the magnitude and extent of intellectual capital disclosure following a transition to mandated sustainability reporting may limit future firm valuation particularly of heavy intangible asset-oriented firms.

Initial study empirically investigating the impact of the transition from a voluntary to mandated sustainability reporting regime on the magnitude and extent of intellectual capital disclosure.

This paper aims to comparatively examine the impact of the intellectual capital performance on the financial performance of Islamic and conventional banks in the Gulf Cooperation Council (GCC) countries by classifying intellectual capital as human capital, knowledge creation and innovation processes.

Along with the theoretical discussion in essentialising the rationale for intellectual capital formation through Islamic norms, the empirical analysis is formulated through the data generated by disclosure analysis using a panel of five GCC countries examining 408 annual reports from 19 Islamic and 23 conventional banks covering 2010–2019 period. In the analysis of the generated data, both fixed and random effects regression models are used.

The findings of this paper suggest that Islamic banks perform better than conventional banks in creating intellectual capital through knowledge creation, human capital and intellectual contribution. While the intellectual capital disclosure index and its pillars are significant for Islamic banks, these variables are not significant for the conventional banks in the GCC countries.

Considering that disclosed information may not reflect actual experience and performance, factual data could also be used to overcome potential shortcomings of disclosure generated data.

This paper demonstrates that Islamic banks in the GCC have been successful in their intellectual capital performance, whereby they seem to be performing in line with the Islamic ontology. In addition, the disclosure items used in this paper may guide the Islamic and conventional banks in the process of preparing their annual reports. Importantly, they may use these items as benchmarks in further developing their intellectual capital performance for better financial performance.

This paper essentialises knowledge development and innovation for Islamic banks through the Islamic cognitive system rather than as a requirement of the market mechanism. Secondly, a comparative analysis between Islamic and conventional banks is presented by acknowledging the peculiarities of Islamic banks in the methodology and disclosure index.

The paper seeks to investigate the key drivers and level of voluntary disclosures in biotechnology company annual reports.

The paper uses an intellectual capital disclosure index score of voluntary disclosures in a large sample of listed biotechnology companies, and tests the relationship between voluntary disclosures of intangible firm value with traditional agency theory variables. The relationships are tested statistically using correlation and multiple‐regression analysis.

The key drivers of voluntary intellectual capital disclosures were the level of board independence, firm age, level of leverage and firm size. Multiple regression analysis demonstrated that board independence, leverage and size had a significant relationship with the level of voluntary intellectual capital disclosure. Separate regression controlling for large‐sized and small‐sized firms demonstrated that voluntary intellectual capital disclosure was only driven by board independence and the levels of firm leverage in large firms. Small firms did not demonstrate this relationship.

The implications of this research are that smaller biotechnology companies' managers are not motivated by external debt‐holder demands to make voluntary disclosures about intangible firm value. In addition, large biotechnology companies, which are better able to establish independent board oversight, appear more effective at driving voluntary intellectual capital disclosures, perhaps in response to greater demand by owners. A limitation of this study is its Australian context and that data is analysed only from 2005 financial year annual reports.

To the authors' knowledge this is an original paper whose findings have valuable implications for managing intellectual capital at the firm level. The paper clearly demonstrates that disclosures about intangible firm value is being driven by traditional agency theory variables and more contemporary corporate governance issues, and that small firms may be ignoring the importance of disclosing more about their intellectual capital.

The main purpose of this chapter is to investigate the association between intellectual capital disclosure (ICD) level and two potential explanatory determinants: industry type and company size.

Twenty-one annual reports of Romanian public companies represented the sample companies. For each company, an ICD index was constructed based on an intellectual capital (IC) framework composed of 33 IC items. The results obtained for ICD Index are then used for statistical testing: descriptive statistics, T test, Pearson correlation, and multiple regression analysis.

Industry type by its own does not seem to influence ICD level and company size by its own does not influence the IC disclosure. However, the combination of the two variables significantly combines together to predict ICD.

A specified list of IC items may not provide the whole picture of ICD practices. Future research could consider interviewing managers about their disclosure rationale. A larger sample could help to further improve the extrapolation of the results. Furthermore, this study challenges researchers to extend the area of analysis by considering the relation between ICD and other possible determinants. Last but not least, a longitudinal study could provide more insights.

The results obtained represent a basis for comparison with those obtained by other studies carried out in other developing countries. Furthermore, they can be used in meta-analysis.

This chapter is one of the first investigating ICD in the case of Romanian companies. Accordingly, our chapter contributes to the ICD literature by providing new empirical evidence on the determinants of ICD in a developing country context.

The purpose of this paper is to explore a new way to disclose intellectual capital (IC) in universities through their websites. Going beyond traditional tools used for intellectual capital disclosure (ICD), this study aims at identifying possible determinants of ICD via the web.

This paper analyses the institutional websites of a sample of Italian universities adapting the theoretical framework developed by Low et al. (2015) to the peculiarities of the Italian university system. Moreover, the relationship between certain explanatory factors identified in previous research and the extent of online ICD represented by two disclosure indexes was tested through an ordinary least squares regression model.

The analysis reveals the extensive use of ICD via websites, especially regarding human and internal capital, while the disclosure of external capital through this means is still limited. Internationality and online visibility both positively affect the extent of a university’s ICD.

The paper represents the first study investigating online ICD and its determinants in universities, contributing new knowledge to help answer the how and what of the matter.

The results can serve as encouragement to university managers to enhance online ICD to meet the information needs of a wider audience.

This is the first study to provide evidence about online ICD in universities and to reveal some of the possible determinants to improve this disclosure.

The purpose of this paper is to study the influences of corporate governance on intellectual capital disclosures in chief executive officers’ (CEOs’) statements in annual reports.

Index score, word count and overall tone of CEOs’ intellectual capital disclosures are calculated to represent the extent, amount and tone of these disclosures, respectively. With a sample of 78 FTSE 100 companies, this paper uses content analysis and empirical analysis to examine the impacts of board size, board composition and shares concentration on the above three measures of CEOs’ intellectual capital disclosures, controlling for company size, profitability and leverage ratio.

Empirical results demonstrate a significant positive relationship between board composition and the extent, amount and tone of CEOs’ intellectual capital disclosures and a significant negative relationship between shares concentration and the amount of these disclosures.

This paper focuses on the impacts of corporate governance on CEOs’ intellectual capital disclosures. It also groundbreakingly measures the tone of CEOs’ disclosures.

The matter of interest is the reporting and disclosure of intellectual capital (IC) in the global “knowledge economy” era. The aim of the paper is twofold: to verify the level of disclosure of IC through the non-financial statements (NFSs) published by public companies and to identify the main firm-specific factors that explain the propensity to disclose.

Based on the 27 components of IC, a scoring system is designed to measure the level of disclosure of IC by 47 listed Italian companies. Content analysis (CA) is performed on the NFSs these companies published in 2020, to measure each company's so-called intellectual capital disclosure index (ICDI). A regression analysis is then applied to relate the ICDI scores to some firm-specific variables to determine their relevance and influence on the level of disclosure.

Although the NFS was not designed specifically for IC, the results of the analyses show an overall barely satisfactory ability of the NFS to give certain information on IC. Furthermore, the propensity to disclose IC appears significantly related to some firm characteristics considered here, such as capitalization, profitability, productivity, intangibility and financial structure.

The analysis relates to a representative but limited sample that does not allow for sectoral or time-series analyses. Extending the companies and years under observation would allow the results to be validated with broader and more in-depth analysis.

This paper provides exploratory but interesting evidence about the relationships between IC disclosure (ICD), firm characteristics and market capitalization. Despite several previous studies on the disclosure of IC, no analyses were found that focused on the information capacity of the NFS. Also, to the authors' knowledge, relatively few researchers have considered a set of financial ratios that include capital structure indices.

The purpose of this study is to investigate the intellectual capital disclosure (ICD) practices of financial institutions in an emerging economy of Bangladesh.

Based on 93 items of intellectual capital categorized into internal capital, external capital and human capital, ICD index is developed for 53 financial institutions listed in Dhaka Stock Exchange. This study uses descriptive statistics to analyze ICD practices, and parametric and non-parametric tests to analyze the variation of ICD practices in terms of different categories as well as in terms of different sectors.

Results indicate that more than 70% of ICD items are generally not disclosed by financial institutions in Bangladesh. The highest of 36% of external capital disclosure items are disclosed, whereas the lowest of 18% of human resource capital elements are disclosed. Furthermore, results find the significant variability of ICD practices in terms of different intellectual capital categories and in between banking companies and non-banking financial institutions.

Findings have critical implications for managers, policymakers and regulators for setting appropriate strategies and regulations for improving the level of ICD, which, in turn, may reduce the information asymmetry problems of financial institutions as well.

In-depth analysis about variability of ICD practices creates value in the ICD literature by highlighting strategic priority of financial institutions to disclose information about the strategic resources in unique emerging economic settings such as Bangladesh.

The purpose of this paper is to investigate the extent and quality of voluntary intellectual capital disclosure (ICD) by deposit money banks (DMBs) in Nigeria.

Data were collected from a survey of 271 informants and content analysis of the annual reports of 12 DMBs in Nigeria. The data collected were analysed using factor analysis, t-test, Friedman test for related sample and Wilcoxon signed-rank test.

The findings of this paper indicate that the extent of ICD is significant and higher than the quality of ICD, which is insignificant, with the extent of disclosure highest in the relational component of intellectual capital. It also shows that a significant difference exists amongst the extent of human capital, structural capital and relational capital disclosures, with the significant difference traced to the difference between the extent of disclosures of relational capital and human capital.

The results can be interpreted across the target sample where the study covers a five-year period and 12 DMBs in Nigeria. However, the study provides a robust empirical basis for policymakers and regulators to develop future ICD regulatory guidelines for banks and push for improvement in the quality of ICD by DMBs.

No previous studies of voluntary ICD have considered the extent and quality of ICD by DMBs in Nigeria. Further, this study shed the light on a new human capital item related to “employee health and mental state”; therefore, it extends and supports the previous empirical literature on ICD.

This paper aims to examine the relationship between the level of intellectual capital information voluntarily disclosed in the annual reports of companies listed on the Kuwait Stock Exchange (KSE) and their market and financial performance.

The classical framework developed by Sveiby (1997) and modified by Guthrie et al. (2006) forms the basis for the content analysis of annual reports published by KSE-listed companies in 2013. An intellectual capital disclosure (ICD) index is developed from this material. Two traditional indicators of corporate performance, namely, market-to-book ratio and return on assets are used to assess market and financial performance. Regression models are constructed to examine the association between the level of ICD and corporate performance.

Empirical findings indicate that better ICD has a positive, statistically significant impact on corporate performance. More specifically, the findings suggest that intellectual capital reporting plays a significant role in enhancing market and financial performance.

This study only focuses on intellectual capital information disclosed in annual reports; other means of corporate communication were not considered. Nevertheless, the annual report has stood the test of time as the best source of corporate disclosure.

Given the importance of intellectual capital reporting in enhancing corporate performance, a practical implication of this study is to make managers aware of its positive and significant effect on market and financial performance, which may encourage companies to develop better disclosure policies. An important implication of the findings is that the policymakers and regulators need to encourage listed companies to disclose their intellectual capital information to exploit the associated benefits.

This paper extends the literature by examining the influence of ICD on corporate performance in the context of frontier markets, where economic, social, political and cultural conditions have particular characteristics.
