The Effect of Voluntary Sell-off Announcements on Shareholder Wealth

Sell-off activities arise when a firm sells part of its assets (e.g., a segment, a division, etc.) but continues to exist in essentially the same form. This study investigates the effect of voluntary sell-offs on stock returns. From a sample of over 1000 sell-off events (first public announcements), the evidence shows that both sellers and buyers earn significant positive excess returns from these transactions. The excess returns earned by buyers are smaller than those earned by sellers. There is also evidence that sell-off announcements are preceded by a period of significant negative returns for the sellers which suggests that the sellers, on average, performed poorly prior to their sell-off activities.     

The Effect of Voluntary Spin-off Announcements on Shareholder Wealth

This paper presents estimates of the effect of a voluntary spin-off announcement on shareholder wealth. The results show that spin-off announcements have a positive influence on stock prices and that the relative increase in share price is greater for large spin-offs than for small ones.

Shareholder Wealth Effects of the Private Securities Litigation Reform Act of 1995

This paper investigates the reaction ofstock prices to enactment of the Private Securities LitigationReform Act of 1995 (PSLRA). Based on a sample of 489 high-technologyfirms, we find that the PSLRA was wealth-increasing, on average,and that the market reaction is more positive for firms at greatestrisk of being sued in a securities class action. However, wealso show that the PSLRA was less beneficial for firms likelyto be the subject of a meritorious lawsuit. Collectively, ourevidence implies that shareholders generally benefit from restrictionson private securities litigation, although these benefits aremitigated when other mechanisms for curbing fraudulent activityare inadequate.     

Excess Asset Reversions and Shareholder Wealth

The ownership of pension assets in a defined benefit pension plan is an unresolved issue in corporate finance. The issue is important because it defines the appropriate investment policy for a pension fund. In this paper, we summarize the ownership debate in the form of two mutually exclusive theories. We then focus on a recently popular event in pension finance, excess asset reversions. Our paper demonstrates the valuation effects associated with this event in a stochastic dominance framework. Under certain conditions, a reversion constitutes an expropriation of wealth from the participants and beneficiaries of the plan to the firm. Using data provided by the Pension Benefit Guaranty Corporation and the Center for Research in Security Prices tape, we examine the returns to the shareholders of 58 companies which conducted excess asset reversions between 1980 and 1984. Our results show that large abnormal returns accrued to these shareholders around the time of the reversion. These findings have implications both for the appropriate investment policy of pension funds and for public policy with respect to plan terminations.     

Tax Policy and Shareholder Wealth: Some Evidence from the Tax Reform Act of 1986

This paper presents additional evidence regarding the stock market reaction to the Tax Reform Act (TRA) of 1986. A prediction model of the change in the profitability index for thirty-three industry groups as a result of the TRA is developed. This prediction model is then tested by examining abnormal industry returns surrounding the announcement of the TRA. The authors find that the distribution of the abnormal returns is related to the distribution of the predicted changes in industry equity investment returns, which suggests that the stock market was efficient in the pricing of news related to the TRA of 1986.     

Poison Pill Securities: Shareholder Wealth and Insider Trading

Existing empirical studies on poison pill securities have examined their overall effect on shareholder wealth. This paper segregates the wealth-increasing poison pills from the value-reducing ones by examining the pattern of insider trading activity prior to the pill adoption announcement. Our results show that pill adoptions that are preceded by net insider purchases are associated with significant stock price increases. This finding is consistent with the proposition that corporate insiders buy their own securities because they do not view the adoption of poison pills as an antitakeover strategy, but rather one that enables the board of directors to extract a greater share of the economic gains from the bidder. Our findings also indicate that firms with net insider sales prior to pill adoption announcement experience generally negative but insignificant changes in value. Finally, firms with no insider trading or with an equal number of insider purchases and sales register marginally significant negative returns.     

Dual Domestic Listing, Market Structure and Shareholder Wealth

This paper examines the impact of dual domestic listing of common stocks on shareholder wealth. The sample contains 137 AMEX- and NYSE-listed companies that dually listed their common stocks on the Pacific and Midwest Stock Exchanges between 1984 and 1988. Because the sample stocks do not have unlisted trading privileges, dual listing changes the market structure in which the stocks traded. Changes in market structure may affect stock returns through the liquidity services provided by the competing markets and through the possible nonhomogeneous clientele across markets. Using standard event methodology to examine stock market behavior around dual listing shows that the net effect of dual listing on returns is negative. Such negative returns suggest that corporate managers have reasons for dual domestic listing other than increasing shareholder wealth.     

A Comment on Excess Asset Reversions and Shareholder Wealth

This study re-examines the earlier finding of Alderson and Chen (1986a) that financial markets do not consider excess pension assets in determining share prices and that significant increases in shareholder wealth occur when an overfunded pension plan is terminated. The results document that specific event-time contamination (corporate restructuring announcements) provides the driving force for all the earlier findings.     

Prior Wall Street Journal Announcements of Possible Bankruptcy Filings and Price Reactions to Subsequent Bankruptcy Filings

This study examines the relation between prior Wall Street Journal (WSJ) announcements of possible bankruptcy filings and price reactions to subsequent bankruptcy filings for 336 firms that filed for bankruptcy between 1980 and 1993. Extant research indicates that price reactions to announcements of economic events are inversely related to the amount of surprise in the announcements. Prior WSJ anouncements of possible bankruptcy filings increase the markets a priori assessment of firms' probability of bankruptcy, thereby potentially reducing the surprise in subsequent bankruptcy filings. We hypothesize smaller price reactions to bankruptcy filings for firms where the WSJ previously published an article indicating that the firm may file for bankruptcy. Our results are consistent with this hypothesis. Specifically, we find smaller price reactions to bankruptcy filings for firms with prior WSJ announcements of possible bankruptcy filings. Our results hold after controlling for firm size, probability of bankruptcy, exchange listing, leverage, and predisclosure information.     

Corporate Mergers and Shareholder Wealth Effects: 1977-1986

The paper investigates the distribution of returns to shareholders of UK companies involved in acquisitions during the period 1977-1986. Three control models were used in the analysis: the market model with parameters identified through OLS regression, a model based on adjusted betas, and finally an index-relative model. Abnormal returns were identified around both bid announcement and outcome dates for bidders and targets in completed and abandoned bids. Examination was also made of the distribution of wealth changes for bidders and targets separately and for both in combination. The results demonstrate that, although there is no net wealth decrease to shareholders in total as a result of takeover activity, shareholders of bidder firms do suffer wealth decreases. By contrast, shareholders in target firms obtained significant, positive wealth increases in both completed and abandoned bids.     

Industry Structure and Ripple Effects of Bankruptcy Announcements

The market structure of an industry plays an important role in determining the stock market performance of surviving firms during intra-industry bankruptcy announcements. On evaluating the announcement effects of a survivor sample from each of two industries with very different market structures, namely the airline industry and the railroad industry, we find that the airline sample received significant abnormal returns (positive ripple) while the railroad sample experienced significant abnormal losses (negative ripple). Furthermore, the differences of the abnormal returns from the two samples also are statistically significant. These findings demonstrate support for the market structure hypothesis (MSH), but cast doubt on the contagion effect hypothesis (CEH).     

Dividend Imputation and Shareholder Wealth: The Case of New Zealand

On April 1, 1988, New Zealand stopped the double taxation of dividends by implementing a full dividend imputation program. Because many believed that the tax advantage of debt had led to more highly leveraged firms subject to greater financial risk than was socially optimal, it was hoped the removal of incentives to finance with debt would result in a more efficient allocation of capital. The empirical results suggest that the shareholder wealth gain from dividend imputation was more than offset in firms with large debt levels. Moreover, an examination of debt ratios indicates debt levels declined in the post–imputation period.

Employee Layoffs, Shareholder Wealth and Firm Performance: Evidence from the UK

Abstract:  We examine the financial performance of UK listed companies surrounding the announcement of permanent employee layoffs. We find that poor operating and stock price performance, increased gearing, and threats from external markets for corporate control precede employee layoffs. Layoff announcements elicit a significantly negative stock price reaction, which is driven by announcements that are reactive to poor financial conditions. We also find that layoffs result in significant increases in employee productivity and corporate focus. We conclude that layoffs represent an efficient response to poor financial conditions, but that their occurrence is strongly dependent on pressure from external control markets.     

The Effect of Golden Parachutes on Shareholder Wealth and Takeover Probabilities

This study seeks to determine whether stockholders experience increases in wealth due to a company's adoption of a golden parachute and resulting increased takeover bid probability. Market reaction to golden parachute adoption is examined by employing event analysis, logit analysis and metric regression. Our findings indicate that the adoption of a golden parachute does not signify an increased probability of a takeover bid, and stockholders experience a decrease in wealth.

Does Shareholder Composition Matter? Evidence from the Market Reaction to Corporate Earnings Announcements

We examine whether institutional ownership composition is related to parameters of the market reaction to negative earnings announcements. When firms report earnings below analysts' expectations, the stock price response is more negative for firms with higher levels of ownership by momentum or aggressive growth investors. There is no evidence, however, that these institutions cause an “overreaction” to earnings news. Ownership structure is also related to trading volume and to stock price volatility on days around earnings announcements. Our findings are consistent with the idea that the composition of institutional shareholders effects stock price behavior around the release of corporate information.     

Shelf Registrations and Shareholder Wealth: A Comparison of Shelf and Traditional Equity Offerings

This study examines the effect of issuing common stock on shareholder wealth under two alternative methods of registration, shelf registration under the Securities and Exchange Commission's Rule 415 and the traditional method of registering shares for immediate sale. The stock price reactions accompanying security registrations and offerings over the period from March 1982 through November 1983 are examined for over two hundred issues. A negative price reaction is observed for traditional and shelf registrations for both utility and non-utility issuers. No statistically significant difference is observed between shelf and traditional registrations. Further negative price reactions precede the offerings of these securities.
