Inside Debt and Mergers and Acquisitions

I empirically investigate the relation between CEO inside debt holdings and mergers and acquisitions (M&As) and find evidence consistent with the agency theory’s prediction of a negative relation between CEO inside debt holdings and corporate risk taking. Further analysis shows that CEO inside debt holdings are positively correlated with M&A announcement abnormal bond returns and long-term operating performance, but negatively correlated with M&A announcement abnormal stock returns. Finally, I find evidence that acquirers restructure the post-merger composition of CEO compensation that mirrors their capital structure in order to alleviate incentives for wealth transfer from shareholders to bondholders or vice versa.

Corporate Governance and Risk-Taking in Pension Plans: Evidence from Defined Benefit Asset Allocations

Based on theoretical advice and empirical evidence suggesting that risk taking in asset allocation enhances pension returns, we evaluate empirically whether good corporate governance leads to a larger allocation of pension assets to risky securities as compared to safe investments. Our findings suggest that firms with good external and internal corporate governance take more risk by investing heavily in equities and allocating a smaller share of the plan assets to cash, government debt, and insurance company accounts. The main underlying mechanisms appear to be higher investment returns and better pension funding status associated with higher equity and lower safe asset allocations.

Pension Contributions and Firm Performance: Evidence from Frozen Defined Benefit Plans

We study the impact of freezing defined benefit (DB) pension plans and replacing them with defined contribution (DC) plans on liquidity, financial leverage, investment, and market value of a sample of firms over 2001-2008. We find evidence that the pension freeze tends to attenuate the drain on corporate liquidity and relieve the pressure to borrow to pay for mandatory contributions (MCs) associated with underfunded DB plans. Although investors seem to favor the pension freeze as evidenced by the positive announcement abnormal stock returns, there is little reliable evidence that the freeze increases investment efficiency and long-term stock performance.

Policy Uncertainty and Mergers and Acquisitions

This research examines the relationship between policy uncertainty and mergers and acquisitions (M&As). We find that policy uncertainty is negatively related to firm acquisitiveness and positively related to the time it takes to complete M&A deals. In addition, policy uncertainty motivates acquirers to use stock for payment and to pay lower bid premiums. Acquirers, on average, create larger shareholder value from M&A deals undertaken during periods of high policy uncertainty, which is attributable to their prudence as well as the wealth transfer from the financially constrained targets to acquirers.

Tournament-Based Incentives, Corporate Cash Holdings, and the Value of Cash

This research examines the relations between tournament-based incentives and corporate cash holdings and the value of cash. We find robust evidence that tournament-based incentives are positively related to cash holdings and the value of cash. Moreover, the effect of tournament-based incentives on the value of cash is stronger for financially constrained firms. Our evidence indicates that as tournament-based incentives motivate riskier corporate policy choices that lead to not only larger expected shareholder value but also greater cash-flow uncertainty, firms increase cash holdings to cushion potential liquidity shortfalls that may cause underinvestment.
