Do stock-for-stock merger acquirers manage earnings? Evidence from Japan

This paper examines the earnings management behavior of Japanese merger acquirers on the Tokyo Stock Exchange. Most Japanese mergers are transacted via stock swaps, when acquirers have incentive to manage pre-merger earnings to reduce the cost of acquisition. Consistent with this incentive, Japanese acquirers have significantly positive long-term abnormal accruals in the year prior to the merger announcement. Further analyses suggest that acquirers’ extent of earnings management is an increasing function of their economic benefit at stake, and a decreasing function of monitoring by banks and foreign investors.
