Purpose
This study aims to identify the differences between local and foreign companies’ social and environmental disclosures (SEDs) practices operating in the Nigerian oil sector. It aims at distinguishing SED levels by comparing local and foreign companies operating in the oil sector.
Design/methodology/approach
The paper analyses annual reports through content analysis. SED extent and type are measured by the number of sentences. SEDs are further classified into three subcategories according to whether they are negative, neutral or positive disclosures and then their proportions are compared through descriptive analysis. To better understand SED differences, the Kruskal–Wallis and Mann–Whitney–Wilcoxon tests are used.
Findings
Local companies are found to provide more content and a wider variety of SED than foreign companies. The majority of the total SEDs in both local and foreign companies are positive with very little evidence of negative news.
Research limitations/implications
The measurement of SEDs focuses on only annual reports, without consideration of other disclosure media such as standalone reports and corporate websites. SEDs are assumed to be voluntary for the companies and they may choose not to disclose any information in annual reports, as there are no regulations or disclosure guidelines in Nigeria to be followed.
Originality/value
The main contribution of this study lies in identifying the factors that have led to diversity and uniqueness in SED between local and foreign oil companies. As such, this study seeks to contribute to the development of understanding multiple factors that could give rise to changing patterns of SED.
Purpose
This study seeks to examine the quantity and quality of social and environmental disclosures (SEDs) of Nigerian oil companies. The study aims to analyse SED activities as reported by the oil companies in their annual reports.
Design/methodology/approach
The study analyses annual reports through content analysis. SED quantity is measured by alternative two units: number of sentences and number of pages. A two-point scale system to assess SED quality is used as follows: 1 = if SED is quantitative and reports specific activities of a company concerning its social and environmental responsibility; 0 = otherwise. Correlation analysis is performed among the different SED categories to identify the relationships among them. Kolmongrov–Smirnov and Shapiro–Wilk tests for normality are utilised.
Findings
SED activities are reported by most of the companies, and by quantity, employee information is found to be the most common type of disclosure. SED quantity and quality in the environment category is found to be overwhelmingly low despite the large-scale public concern expressed about the levels of the environmental degradation caused by oil company operations.
Research limitations/implications
The data collected for this study are based on one country, which controls diversity but limits the generalizability of the findings. The study is limited by the sample which includes mainly quoted companies, as they are believed to make improved disclosures because of their investor orientation and statutory obligations.
Originality/value
The study extends SED research by focusing on social disclosures such as employee-, community- and health- and safety-related disclosures. The study also investigates the motivations of SED providers and establishes a link between stakeholder demands/engagement and the level of disclosure.
