The Information Content of Defence Documents in UK Hostile Takeover Bids

This study examines the defence documents of 79 hostile take-over bids of publicly quoted companies in the UK during the period 1988–1990 using logit regression and discriminant analysis to determine if any of the 41 identified characteristics of the defence document and seven continuous control variables lead to a higher or lower probability of a successful defence. The study finds that managers in target companies are unable to introduce new information in their defence documents that materially affects the outcome of a bid. This suggests that managers may advise shareholders to reject a bid for other reasons, such as to drive up the offer price.
