How diverse are Shariah supervisory boards of Islamic banks? A global empirical survey
(Emerald Publishing, 2022) Kachkar, Omar; Yılmaz, Mustafa Kemal; Yılmaz, Mustafa Kemal; Kachkar, Omar; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Purpose – This study examines diversity in the composition of Shariah Supervisory Boards (SSBs) of Islamic banks (IBs). It investigates diversity from two perspectives: 1) existing composition of SSBs, and 2) the regulatory frameworks and standards of selected Organization of Islamic Cooperation (OIC) countries. Diversity characteristics in this study include education, nationality, gender, and age. Design/methodology/approach – A list of all full-fledged Islamic commercial banks (FFICBs) globally has been carefully prepared and confirmed. Conventional banks with Islamic windows, non-commercial banks, takaful companies and other Islamic financial institutions are excluded. The available profiles of 428 SSB members have been scrutinised and analysed. These board members occupy 522 SSB positions in 238 FFICBs operating in 52 countries around the globe. From the regulatory perspective, twelve national and international Shariah governance frameworks and standards have been examined. Findings – The findings indicate various levels of diversity in the SSBs of the IBs. The level of diversity in educational background and nationality of the SSBs are generally acceptable. However, lack of diversity in gender and age among the SSB members is evident. While the lack of age diversity in SSBs maybe relatively justified as a common trend in the composition of corporate boards, the SSBs of FFICB are seriously lagging conventional banks in gender diversity. On the regulatory side, these results show that provisions on diversity requirement in the SSBs are almost non-existent in the existing frameworks and standards. Research limitations/ implications – The major limitation of this study is the lack of available information on the SSB members. Practical implications – This paper provides valuable insights for Islamic banks and policy makers concerned with the corporate governance of Islamic financial institutions. First, it offers an excellent bird’s-eye view of the status of diversity in the SSBs of Islamic banks. Second, it motivates policy makers and standard-setting bodies to ensure an adequate level of diversity in the composition of SSBs through relevant regulatory frameworks. This is of paramount importance to the reputation of Islamic finance industry which has been subject to mounting pressure to translate the rhetoric about the Islamic finance industry being ethical, fair, just, equitable and inclusive into genuine implementations. Originality/value – To the best of the authors’ knowledge, this study is the first of its kind to examine the diversity of the SSB members from the regulatory as well as implementation perspective.
Does board diversity affect the cost of debt financing? Empirical evidence from Turkey
(Emerald Publishing, 2023) Aksoy, Mine; Yılmaz, Mustafa Kemal; Yılmaz, Mustafa Kemal; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Purpose – This study aims to investigate the effects of board characteristics on the cost of debt for nonfinancial companies in the Turkish capital markets. Design/methodology/approach – Using a sample of 211 non-financial companies listed on Borsa Istanbul, this study examines how chairperson gender and board characteristics affect the cost of debt by using panel data analysis over the period of 2016–2020. A system generalized method of moments model is also applied to test the endogeneity issue. Findings – The findings show that the presence of female chairperson and female directors on board reduces the cost of debt and the perceptions of default risk by fund providers, while board independence and board size do not have a significant impact on the cost of debt. The results provide insightful information for companies and policymakers. Companies can alter board composition through gender diversity, while policymakers can introduce new policies in encouraging the presence of female directors on boards. Originality/value – This study primarily enriches the literature on the effect of board diversity on debt financing cost in a leading emerging market, enabling companies in emerging markets to better mitigate agency costs and finance their investment through effective board composition. Second, it provides evidence that financial institutions consider companies with chairwomen and women directors on the boards less risky and charge them less for debt financing than they do for companies with man chairperson. Finally, the results support policymakers to take actions to increase female presence on board.
The impact of ownership structure, board attributes and XBRL mandate on timeliness of financial reporting: Evidence from Turkey
(Emerald Publishing, 2021) Aksoy, Mine; Yılmaz, Mustafa Kemal; Topçu, Nuraydın; Uysal, Özgür; Yılmaz, Mustafa Kemal; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Purpose – The purpose of this study is to investigate the effects of ownership structure, board attributes and eXtensible Business Reporting Language (XBRL) on annual financial reporting timeliness of non-financial companies listed on Borsa Istanbul (BIST). Design/methodology/approach –To conduct the analyses, the authors used two samples. The main sample consists of 187 companies, while the subsample includes 54 companies in the BIST 100 index. The data set covers the 2010–2018 period. To investigate the influence of ownership structure, board attributes and XBRL on timeliness, panel regression and univariate analyses were used. To explore the factors associated with the likelihood of late filing, panel logistic regression analyses were employed. Findings –The findings provide evidence that companies that have a high level of institutional ownership and women board membership file earlier. In line with prior studies, profitable companies file their accounts faster. Highly leveraged companies are late reporters. Further, XBRL has a positive influence on the filing of financial reports for the BIST 100 companies due to technological agility. Finally, companies that have less institutional ownership and that get qualified audit opinions are more subject to late filing. Research limitations/implications – The authors acknowledge that this study has certain limitations. First, the results may not be generalized to the entire BIST population due to the exclusion of financial companies from the samples. Future research may explore the financial reporting timeliness of these companies. Second, the study did not investigate the relationship between timeliness and the information content in financial statements and the market reactions they arouse. Third, this study is trying to find out early evidence on the mandatory adoption of XBRL filings, which cover only three-year period due to the recent implementation of this regulatory practice. Thus, it needs further elaboration after the accumulation of data in the forthcoming years by the expansion of the sample beyond the 2016–2018 period. As companies would have more time to become familiar with XBRL, a more reliable conclusion may be drawn. Further, the study particularly focuses on the effect of XBRL adoption on the timeliness among filers. XBRL could also influence investors, auditors and other stakeholders. Future research could investigate the influence of XBRL on different stakeholders to produce more insightful implications. Practical implications – This study offers several implications for managers, regulators and policy makers. First, companies that do not make timely financial reporting may find it more difficult to attract long-term capital by means of institutional investors. Since these investors view timely reporting as an ideal ingredient in corporate governance, it may have a positive impact on company reputation and corporate sustainability. The results also provide insights for regulatory authorities, policy makers and auditors on the causes of the reporting lag, thereby increasing their awareness and helping them in their decision-making process since improvements in timely availability and accessibility of financial information reduce information asymmetry for users and increase market efficiency. Additionally, companies that reduce their filing timeframe will be able to compare their results with other companies. However, the XBRL mandate could be much more burdensome to smaller firms. This may stem from the fact that larger firms may tend to use the in-house approach for XBRL and can afford more advanced financial reporting systems with automated coding algorithms attached to streamline their XBRL filings, whereas smaller firms are more likely to use the outsourcing approach due to the difference in the level of resources available for XBRL preparation. This finding also lends support to recent concerns that new technology creates an unleveled benefit in reporting efficiency for large companies, but not for small ones (e.g. Blankespooret al., 2014). This benefit may change the dynamics of the financial market and information environment, leading to further segmentation of the capital markets. The positive effects of XBRL adoption may accrue over time due to the potential benefits of learning curve experience since the XBRL mandate will help companies automate their reporting process and information processing, thereby strengthening internal control over financial reporting (Deloitte, 2013; Du et al., 2013; Li, 2017). Companies may also efficiently incorporate auditor-proposed adjustments by cross-referencing impacted accounts and prepare revised versions of the financial reports, which are automatically rendered in various formats for auditors to assess (Wu and Vasarhelyi, 2004). Finally, investors and other users of financial information benefit from having quicker access to data, since this allows them to make more timely and reliable decisions, leading to greater benefits. Originality/value – This paper contributes to the literature on the impact of adopting XBRL on the timeliness of financial reporting in emerging markets. Second, this study extends the literature and provides evidence on determinants of timeliness, covering both ownership structure and board attributes besides firm-specific characteristics. Hence, it provides valuable insights for companies, investors, auditing firms and policy makers.
Social media adoption and export intensity: The moderating role of firm size
(Emerald Publishing, 2023) Altınkaya, Zelha; Yılmaz, Mustafa Kemal; Aksoy, Mine; Seçme, Zekeriya Oğuz; Yılmaz, Mustafa Kemal; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Purpose: Social media (SM) networks offer a golden opportunity for firms that particularly engage in international activities to set up sustainable customer relationships and improve competitiveness. The purpose of this study is to examine the influence of SM adoption on the export intensity (EI) of firms listed on Borsa Istanbul (BIST) for the years 2010–2020. The authors use social media index (SMI) to measure SM adoption and firm size (FSize) as a moderator on exploring the interaction of SM and EI. Design/methodology/approach: Using a sample of 150 firms listed on the BIST Industrials Index, this study explores how the adoption of SM affects EI by using panel data analysis over the period of 2010–2020. Findings: The results indicate that the SMI has a positive and significant effect on the EI. FSize positively moderates the interaction of SMI and EI, indicating that large firms benefit more from the SM in increasing export performance. The findings reflect high potential of EI improvement through adopting right SM policies in emerging markets. Research limitations/implications: The sample covers only public companies listed on the BIST Industrials Index. Future studies may extend the coverage and include multiple emerging markets to draw generalized results for the export-oriented firms. This research also analyzes solely four SM networks, i.e. Facebook, Instagram, Twitter and YouTube. However, there are many other SM networks that firms use in online marketing in foreign markets. Finally, this research did not discuss the potential factors that could influence the use of SM in emerging market firms. Practical implications: This study denotes the significant role of SM adoption on the EI of firms in an emerging market setting from the perspective of resource-based view. It presents an insightful approach in understanding the mission played by SM networks in enhancing the EI of Turkish firms. Policymakers may use the findings to develop public support programs to promote the adoption and implementation of the SM among exporting firms in emerging markets. Originality/value: The study provides evidence on the effects of SM adoption on the EI from the perspective of emerging countries. It also helps to gain a deeper understanding of how different SM platforms contribute to the internationalization of firms.
