However, both prior to and subsequent to the bid announcement month, the overseas bidders earned highly significant negative abnormal returns. The cumulative abnormal returns over the five month period following the bid announcement were -4.77% with the index model and -9.79% with the market model.Further analysis established that Continental European companies performed significantly worse than American bidders.
