Voluntary disclosure practices amongst listed companies in Nigeria

This study examines voluntary disclosure practices amongst listed companies in Nigeria. Results from univariate and multivariate analyses of 52 listed companies suggest an average voluntary disclosure of 44% based on modified Meek, Roberts and Gray (1995) disclosure index comprising 24 disclosure items. The study found significant positive relationship between voluntary disclosure and firm size, measured as the natural logarithm of total asset. The study documents significant positive relationship between market-based definition of firm performance and voluntary disclosure. The study also found significant negative relationship between percentage of block share ownership and percentage of managerial share with firm disclosures. The study has important implication for both individual and institutional investors globally, regulators and policy makers in developing economies. (C) 2011 Elsevier Ltd. All rights reserved.
