Impact of Ownership Concentration on Accounting Voluntary Disclosure Reporting: Evidence From Listed Firms in the Down-Stream Sector of the Nigerian Petroleum Industry
Abstract
This study examines the impact of ownership concentration on Voluntary Disclosure by firms in the downstream
sector of the Nigerian petroleum industry over the period of ten years (2001 – 2010). A sample of seven firms listed on the
floor of Nigerian Stock Exchange was studied. The study made use of secondary data generated from annual reports and
accounts and the Nigerian Stock Exchange Fact book of the sampled companies. The data was analyzed by means of
descriptive statistics and regression analysis using SPSS package (Version 20). The results reveal that ownership
concentration being one of the major determinants of corporate governance has significant positive association with the
extent of voluntary disclosures. Based on the findings, the study recommends among others: That the oil marketing and
distribution companies should encourage concentration of shares to a certain degree, so that managerial influence affecting
voluntary disclosure would be offset through the pressure from the block-holders.
