Purpose -This paper contributes to the existing disclosure literature by examining the determinants of narrative risk information in the interim reports for a sample of UK non financial companies.Methodology -This study uses the manual content analysis to measure the level of risk information in interim report narrative sections prepared by 72 UK companies. It also uses the OLS regression analysis to examine the impact of firm-specific characteristics and corporate governance mechanisms on narrative risk disclosures.Findings -The empirical analysis shows that large firms are more likely to disclose more risk information in the narrative sections of interim reports. In addition, the analysis shows that industry activity type is positively associated with levels of narrative risk disclosure in interim reports. Finally, the analysis shows statistically insignificant impact of other firmspecific characteristics (liquidity, gearing, profitability and cross-listing) and corporate governance mechanisms on narrative risk disclosure.Practical implications -The study's findings have practical implications. It informs investors about the characteristics of UK companies that disclose risk information in their interim reports. For example, the findings shows that narrative risk disclosures is affected by firm size and industry type rather than firms' risk levels (e.g. financing risk measured by the gearing ratio or liquidity risk measured by lower liquidity ratios). Practical implications for managers from these findings are that, in order to keep investors satisfied, companies with high levels of financing and liquidity risks should look at investors' demands for risk disclosure. This will help investors when making their investment decisions.Originality/value -The determinants of narrative risk disclosure in interim reports has not been explored so clearly in prior research and therefore this study is the first of its kind to examine this research issue for a sample of UK companies.
