“Aggregated, voluntary, and mandatory risk disclosure incentives: Evidence from UKFTSE all-share companies”, as the name suggests, is a critically acclaimed attempt at examining, analyzing and critiquing the existing trends in the aggregated, voluntary and mandatory risk disclosure incentives that are evaluated by various companies before deciding their respective risk disclosure policies. The context of this study is derived from various all-share companies based in the UK and/ or listed in the FTSE 100 index. The primary author of this paper, Dr. Tamer Elshandidy, is a Lecturer in Accounting at the University of Bristol, the United Kingdom. Accepted for publication by the International Review of Financial Analysis, the research paper was a product of several critical suggestions as well as feedback from eminent financial experts at the 4th European Risk Conference (Nottingham University, 2010), the British Accounting Association Conference (Cardiff University, 2010), the ICAS Research Workshop (Edinburgh, 2010) and the 13th Scottish Doctoral Colloquium (University of Stirling, 2009).As suggested earlier, the paper in this context seeks to examine, analyze and evaluate the trends driving the impact of corporate risk on various kinds of aggregated, voluntary and mandatory risk disclosures, all taken from the annual report narratives of various UK-based, FTSE 100 listed companies in the non-financial domain. The firms chosen for this study were characterized in terms of the levels of systematic financing risks; risk-adjusted returns, size, dividend-yield, stock return variability, board independence, audit environments as well as insider-outsider ratio in terms of ownership within the firm.
