Reversions of Excess Pension Assets after Takeovers
研究收购后企业回收超额养老金资产的现象，发现敌意收购后两年内15.1%的收购方回收了养老金，而友好收购后仅8.4%，回收主要发生在单位福利计划中，可解释约11%的收购溢价。
This article evaluates pension asset reversions as a source of takeover gains. In our sample of 413 takeovers, pension funds were reverted by 15.1% of acquirers in the two years following hostile takeovers compared to 8.4% in the two years following friendly takeovers. Reversions following takeovers tend to occur in unit-benefit plans, where the potential for wealth transfer is the greatest. These results are consistent with the view that hostile takeovers breach implicit contracts between firms and employees. We estimate that the reversions can on average explain approximately 11% of the takeover premium in cases where they actually occur. Reversions are too small to be the sole, or even dominant, source of takeover gains.
