Purpose

The purpose of this paper is to construct an investment account holders' transparency and disclosure (IAH-T&D) index based on the new and revised accounting standard for investment accounts of the Accounting and Auditing Organization for Islamic Financial Institutions Standards (AAOIFI) (2020). It also aims to measure and compare the compliance level with IAH-T&D over years and between countries.

Design/methodology/approach

This study uses the content analysis method to analyze the content of 270 annual reports across 30 Islamic banks (IBs) in 10 Middle East and North Africa countries during the period from 2010 to 2019.

Findings

This study introduces a new IAH-T&D index which consists of 27 items representing four categories: investment accounts disclosure (11 items), incentive earnings disclosure (1 item), allocations and reserve disclosure (4 items) and general requirements for disclosure (11 items). The analysis shows that the level of IAH-T&D is 51%. The level of compliance varies over the years and across countries.

Originality/value

To the best of the authors’ knowledge, this is the first study that offers an original self-constructed-T&D index that could enhance future research related to determinants and consequences of IAH-T&D practice in IBs.

遵守投资账户持有人的透明度和披露要求：来自中东和北非地区的证据

目的

本文的目的是根据伊斯兰金融机构会计和审计组织标准（AAOIFI）（2020）新修订的投资账户会计准则构建投资账户持有人透明度和披露（IAH-T&D）指数。它还旨在衡量和比较多年来和国家之间 IAH-T&D 的合规水平。

设计/方法论/途径

本研究采用内容分析法对2010年至2019年期间中东和北非10个国家30家伊斯兰银行（IB）的270份年度报告内容进行了分析。

发现

本研究引入了新的IAH-T&D指数，该指数由代表四类的27个项目组成：投资账户披露（11个项目）、激励收益披露（1个项目）、分配和储备披露（4个项目）以及披露的一般要求（11个项目） ）。分析显示IAH-T&D水平为51%。多年来，不同国家的合规水平各不相同。

原创性/价值

据作者所知，这是第一项提供原创的自行构建的 T&D 指数的研究，该指数可以增强与 IB 中 IAH-T&D 实践的决定因素和后果相关的未来研究。
