The study examined the relationships between firm characteristics and corporate governance (CG) attributes and IR disclosure among companies listed on Bahrain Stock Exchange (BSE). An index of 31 items of IR disclosure was used. It was found that of the 40 companies included in this study, 34 (85%) had accessible websites and of the 34 companies, only 9 (26.47%) companies had a separate section for IR information in their websites. On average, the level of IR disclosure by Bahraini listed companies is relatively high. The univariate statistics showed that there is a significant positive relationship between the IR disclosure index and firm size, board size, and board composition. The finding however revealed a negative relationship between IR disclosure index and firm type and firm performance.
