Governance and Merger Accounting: Evidence from Stock Price Reactions to Purchase versus Pooling

Abstract

This paper examines the effect of corporate governance on investor reactions to accounting choice in the context of accounting for business combinations. Using a sample of 324 recent stock swap acquisitions I find that, contrary to practitioners' belief that capital markets penalize purchase accounting, the opposite appears to be true; there is a negative and significant differential market reaction of approximately 4% for acquiring firms that announce pooling transactions. This return differential declines to negative 8% for firms with ineffective corporate governance. These findings are consistent with capital markets interpreting the choice of purchase accounting as a signal of management's confidence in the likelihood of a successful merger. This signal is particularly relevant when corporate governance is considered ineffective.
