This paper investigates the effect of distance between the acquirer or merger and its target on the performance of mergers and acquisitions in the U.S. property$liability insurance industry. This paper finds mergers and acquisitions that occur within shorter distances are more likely to perform better on ROE, implying the relevance of distance and information advantage and synergy. In addition, this paper finds a positive correlation between the ratio of equity capital to total asset and the performance of mergers and acquisitions, while the ratio of income from stock investment to income from both debt and stock investment and the degree of geographical diversification are negatively correlated with the performance of mergers and acquisitions
