PurposeThe present study aims to examine the relationship between corporate governance factors and financial reporting transparency pre and post of ISIS.Design/methodology/approachA multivariate regression model was used to test the hypotheses for this purpose. The research hypotheses were tested on a sample of 35 companies listed on the Iraqi Stock Exchange from 2012 to 2018 using a multivariate regression model based on panel data technique.FindingsThe results indicate a negative and significant correlation between the board independence, audit committee independence, management team stability and remuneration of the board of directors and financial reporting transparency. In contrast, there is a positive and significant correlation between the board expertise, audit committee expertise and managerial ownership, with financial reporting transparency. Moreover, ISIS has had a direct and significant impact on the correlation between the board of directors’ independence and remuneration with financial reporting transparency. The present study also tested research models using additional methods (such as feasible generalised least squares, ordinary least squares, random effects and T + 1) to obtain better results. The results of these different methods were entirely in line with the main results of the research.Originality/valueThe political and economic instability resulting from the entry of ISIS into Iraq has created severe problems for society’s economic, political, security and performance dimensions. Macroeconomic uncertainty driven by terrorist activities can negatively affect managers’ perceptions of firms’ future performance and result in poor judgments and estimations, significantly impacting business units' financial reporting transparency. Because no study has examined the relationship between corporate governance and financial reporting transparency on the Iraq stock exchange before and after the presence of ISIS, this study examines such a relationship. Although the economic and political situation in Iraq may not be identical to that in other nations, much of the experience in Iraq is anticipated to apply to other countries in the region.
