Deposits structure, ownership concentration and corporate governance disclosure in GCC Islamic banks: Empirical evidence

Abstract

Purpose

This paper aims to assess the effects of deposits structure and ownership structure on the GCC Islamic banks’ corporate governance disclosure (CGD) practices.

Design/methodology/approach

The study is based on a sample of 38 Islamic banks operating in five Gulf Cooperation Council (GCC) countries, and the authors observed them over the period from 2006 to 2011. The authors used the transparency and disclosure score, developed by Standard & Poor’s (S&P), to identify the sample’s CGD scores.

Findings

This paper’s findings suggest that the level of CGD is lower for Islamic banks with higher ownership concentration, for levered Islamic banks and for Islamic banks with greater concentration of nonprofit-sharing investment accounts (PSIA) and is higher for Islamic banks with greater concentrations of PSIA; the Islamic bank size; the bank age; listed bank and the country transparency index. By disaggregating the total CGD into the three sub-categories, the authors are able to specify, also, the components of corporate governance (CG) impacted by various determinants.

Research limitations/implications

This paper is subject to a number of limitations. First, there is manual scoring of annual reports (subjectivity). Second, the research focuses exclusively on the GCC context and excludes the other Middle East, Southeast Asia and Far East countries, where ownership structure and deposits structure might affect CGD differently. Third, the governance score, which is used in this research, is developed by S&P and does not take into account the characteristics of Islamic banks.

Practical implications

The findings of this paper suggest many policy implications. First, through the optimization of ownership structure, GCC countries’ regulators have to improve the Islamic banking system’s CG mechanisms through the optimization of ownership structure (dispersed ownership) to promote transparency and disclosure. Second, regulators and policymakers should revise guidelines with the main purpose of protecting PSIA’ holders (considered to be minor shareholders without voting power) through promoting disclosure and transparency. Third, the findings can be useful for many international supervisory bodies, like the Islamic Financial Services Board (IFSB) and Accounting and Auditing Organization for Islamic Financial Institutions (AAOIFI), in evaluating transparency and disclosure standards.

Originality/value

This study is expected to be useful for all market participants, namely, investors, financial analysts, managers, marker regulators and many international Islamic supervisory bodies, such as the IFSB and AAOIFI, by providing new requirements on CGD in the GCC region and in better understanding its determinants for Islamic banks in this region.
