Effects of Executive Share Option Plans on Shareholder Wealth and Firm Performance: The Singapore Evidence

The main purpose of our paper is to study the institutional nature and characteristics of executive share option plans (ESOPs) in Singapore, a fast-growing economy and an important investment location in Asia. Our study provides an interesting comparison between the characteristics of ESOPs in Singapore and those in the US. Our paper also investigates the short-term market reaction to ESOP announcements and the long-run stock and operating performance of the sample firms following the adoption of the ESOPs. Results indicate weak evidence of a positive abnormal return on the days surrounding the announcement of the ESOPs. However, there is no evidence of long-term superior stock and operating performance for the ESOP firms relative to benchmarks. The lack of significant incentive effects for the sample firms reflects mainly the unique regulatory environment in Singapore.     

The Determination of the Seniority Structure of Debt: Theory and Evidence

The purposes of this paper are to provide a theory of determining the firm's optimal seniority structure of debt and examine the relation between the firm's seniority structure of debt and its characteristics. Unlike previous studies, we develop a theoretical model which explicitly includes the benefits and costs associated with senior debt financing, corporate taxes, risk-aversion in the capital market, and costs of financial distress. We next show how a value-maximized firm searches for the optimal trade-off among the present values of the tax advantage of debt, loss of tax credits, expected costs of financial distress, costs of senior debt financing, and benefit of limited liability. Numerical analysis results show that the firm's value is not only a strictly concave function of its capital structure (with a unique global maximum), but also a strictly concave function of its mix of senior and junior debts (with a unique global maximum). We then show that a firm's optimal seniority structure of debt (i.e. the market value of senior debt divided by the sum of the market values of senior and junior debts) increases for low levels of asset riskiness and decreases when asset riskiness becomes sufficiently great. Our model also suggests that a firm's optimal seniority structure of debt increases for low levels of growth opportunities and decreases for high levels of growth opportunities. We test the predictions of our model on the relation between the firm's seniority structure of debt and its characteristics by using the data for the firms in COMPUSTAT over the 1972 through 1991 time period. The empirical evidence is consistent with our theoretical predictions.     

How do sovereign credit rating changes affect private investment?

Sovereign credit rating changes have an influence on real private investment of re-rated countries. We find significant increases in private investment growth following upgrades in sovereign ratings. These increases, however, are transitory. We also find significant, temporary declines in private investment growth following sovereign rating downgrades. The results hold after accounting for re-rated countries’ growth opportunities, endogeneity, and other factors that could affect private investment. The irreversible nature of investment may be the explanation for the temporary changes in the growth rates of physical capital investment associated with revisions in sovereign credit ratings.     

Bidders’ strategic timing of acquisition announcements and the effects of payment method on target returns and competing bids

Using a sample of acquisition announcements released during trading versus nontrading hours, this study examines how the strategic timing of acquisition announcements determines the impact of the method of payment on target stock returns and competition among bidders. For overnight acquisition announcements, we find that cash payment offers positively and significantly affect acquisition premiums and target returns, yet these results do not hold for daytime announcements. Cash payment offers made during nontrading hours are more likely to deter potential bidders and complete proposed transactions. However, we find no such relationship for daytime announcements. These findings suggest that the timing of acquisition announcements by bidders is important for assessing the effects of payment method as a signal of target valuation and a preemption of competing bids.
