Mergers & Acquisitions, Diversification and Performance in the U.S. Property-Liability Insurance Industry

Abstract

This paper examines the relationship between mergers & acquisitions (M & As), diversification and financial performance in the U.S. property-liability insurance industry over the period 1989–2004. The risk-adjusted return on assets (ROA), return on equity (ROE), Z-score and total risk measured by earnings volatility are considered as a relevant indicator of performance. We find that acquirers’ financial performance decreases and earnings volatility increases during the gestation period after the M & As perhaps due to increased frictional costs associated with post-merger integration and agency problems. We find that more focused insurers outperform the product-diversified insurers, implying that the costs of diversification outweigh the benefits. These findings are robust to alternative risk and diversification measures. We also find that marginal increases in commercial line share are associated with higher risk-adjusted profits, but these gains are offset by the extra costs from product diversity when its initial share is low. For insurers initially concentrated in commercial line, a marginal increase in commercial line share is related to higher performance due to positive effects of both direct exposure and indirect focus.
