Takeover vulnerability and the credibility of signaling: The case of open-market share repurchases

There is debate in the literature focuses on whether open market repurchases can be taken as a signal of stock undervaluation. This research argues that takeover pressures before a repurchase announcement can be a credible signal of undervaluation. The empirical results indicate that repurchasing firms with a higher probability of takeover experience greater announcement effects, improvements in operating performance and long-run abnormal return, positive forecast revisions by financial analysts, and enhanced agreement between management and shareholders. These findings suggest that takeover probability and open-market share repurchases appear to constitute a double-signal for conveying stock undervaluation to the market.     

The Disparate Nature of Targeted Repurchases: Evidence from Long-Run Performance

Abstract:  We examine the announcement stock returns and long-run performance of 352 targeted repurchases from 1979 to 1998. For those repurchases of blocks that are non-control related we find a positive announcement stock price response and positive long-run stock performance indicating that these repurchases are timed to occur when the company's shares are undervalued and that the market underreacts to this signal. In contrast, for those repurchases of blocks that are control related we find a negative announcement stock price response and insignificant long-run stock performance indicating that these repurchases occur for a different reason. We conclude that control related repurchases are utilized solely to dismiss potential takeover bids and are not timed when the stock is undervalued.     

Limited attention,share repurchases,and takeover risk

We hypothesize that announcing open market share repurchases (OMRs) to counter negative valuation shocks reveals repurchasing firms’ lost growth opportunities or underperforming assets to potential bidders, making them more likely to become takeover targets. This also leads their investors to face higher takeover risk, a systematic risk associated with economic fundamentals that drive takeover waves, as proposed by Cremers et al. (2009). Indeed, we find that repurchasing firms tend to face higher takeover probability in the first few years following their OMR announcements, and that the increase in takeover risk can largely explain their post-announcement long-run abnormal returns documented in the literature. The increase in takeover risk is larger for smaller firms, firms with poorer pre-announcement stock performance, and those attracting more attention of market participants. Our results suggest that OMRs, which are used by many firms to counter undervaluation, could make the firms more sensitive to takeover waves and raise their cost of equity capital.     

The Stock Market Reaction to Significant Tender Offer Repurchases of Stock: Size and Purpose Perspective

This paper uses event methodology to examine the impact of common stock repurchases on the repurchasing firm's common stock returns, including examination of various subsamples to test the effects of size and purpose of repurchase. Although the market reacts positively to general repurchase announcements, it reacts negatively to those repurchases used to fend off takeover attempts and does not react at all to stock repurchases for employee stock option plan (ESOP) purposes.     

Does Labor Power Affect the Likelihood of a Share Repurchase?

This research examines the impact of labor power on the firm's repurchase decisions. Firms facing stronger labor power repurchase fewer shares, suggesting that, on average, repurchases are against the interests of labor. However, the negative effect of labor power on repurchases is significantly reduced when repurchases benefit employees by fending off an unwanted takeover or countering the dilution effects of employee stock options. We also examine the ex post consequences of share repurchases. Repurchases are positively related to the probability of a strike. Repurchase announcement returns and the operating performance of repurchasing firms are negatively related to labor power.     

Stock repurchasing and corporate social responsibility

Stock repurchases are controversial. Researchers often view the positive association between free cash flow and the volume of the stock repurchases to be in the shareholders’ interest and the positive association between executive options and stock repurchases to be in the managers’ interest. Using firms’ corporate social responsibility (CSR) ratings as a measure of ethical culture—one that increases the cost of self-serving behavior for managers— we examine whether a firm’s CSR rating is related to its stock repurchase decisions. Although the baseline regression shows a positive association between CSR and repurchases, we find that CSR amplifies the positive association between free cash flow and stock repurchases and lessens the positive association between executive options and stock repurchases. These results indicate that ethical culture might play a role in repurchase decisions: it may encourage repurchases aligned with shareholders’ interests and discourage those primarily in managers’ interest. Furthermore, we also find that high CSR firms are associated with a greater completion rate of announced repurchase programs and receive more favorable stock market reaction to their repurchase announcements.     

The contribution of stock repurchases to the value of the firm and cash holdings around the world

Using corporate payout data from 33 economies, this study investigates the contribution of stock repurchases to the value of the firm and cash holdings in different country-level investor protection environments. We find that stock repurchases contribute more to firm value in countries with strong investor protection than in countries with weak investor protection. We also report that dividends contribute approximately 60% more to firm value than repurchases in countries with weak investor protection. Furthermore, as the proportion of repurchases in total payouts increases, the marginal value of cash increases in countries with strong investor protection, whereas it declines in countries with weak investor protection. In a poor investor protection environment, the marginal value of cash for a firm that makes 100% of its payouts via repurchases is 12 cents lower than that for a firm that distributes 100% of its payouts via dividends. Overall, our findings highlight that stock repurchases are less effective than dividends in mitigating agency problems associated with free cash flow in countries with poor investor protection.     

Signaling and Takeover Deterrence with Stock Repurchases: Dutch Auctions versus Fixed Price Tender Offers

This article presents a model of repurchase tender offers in which firms choose between the Dutch auction method and the fixed price method. Dutch auction repurchases are more effective takeover deterrents, while fixed price repurchases are more effective signals of undervaluation. The model yields empirical implications regarding price effects of repurchases, likelihood of takeover, managerial compensation, and cross-sectional differences in the elasticity of the supply curve for shares.     

VALUATION EFFECTS OF OPEN MARKET STOCK REPURCHASES FOR FINANCIALLY WEAK FIRMS

We test the proposition that announcements of open market stock repurchases improve the flow of positive information regarding the firm's prospects, particularly for financially weak firms. For financially strong firms with already good prospects for cash flows, the role of stock repurchases is less important. We provide evidence for an inverse relationship between financial risk, measured by bond rating, and the magnitude of stock repurchase-induced abnormal returns. Results also suggest that the value of information implied by announcements of open market repurchases about increases in cash flows and leverage, is more important for financially weak firms than for financially strong firms.     

WHAT DO WE KNOW ABOUT STOCK REPURCHASES?

Stock repurchases by U.S. companies experienced a remarkable surge in the 1980s and ‘90s. Indeed, in 1998, the total value of all stock repurchased by U.S. companies exceeded for the first time the total amount paid out as cash dividends. And the U.S. repurchase movement has gone global in the past few years, spreading not only to Canada and the U.K., but also to countries like Japan and Germany, where such transactions were prohibited until recently. Why are companies buying back their stock in such amounts? After dismissing the popular argument that stock repurchases boost earnings per share, the authors argue that repurchases serve to add value in two main ways: (1) they provide managers with a tax‐efficient means of returning excess capital to shareholders and (2) they allow managers to “signal” to investors their view that the firm is undervalued. Returning excess capital is value‐adding for two reasons: First, it helps prevent companies from pursuing growth and size at the expense of profitability and value. Second, by returning capital to investors, repurchases (like dividends) play the critically important economic function of allowing investors to channel their investment from mature or declining sectors of the economy to more promising ones. But if stock repurchases and dividends serve the same basic economic function, why are repurchases growing more rapidly? Part of the explanation is that, because repurchases are taxed as capital gains and dividends as ordinary income, repurchases are a more tax‐efficient way of distributing excess capital. But perhaps even more important than their tax treatment is the flexibility that (at least) open market repurchases provide corporate managers‐flexibility to make small adjustments in capital structure, to exploit (or correct) perceived undervaluation of the firm's shares, and possibly even to increase the liquidity of the stock, which could be particularly valuable in bear markets. For U.S. regulators, the growth in open market stock repurchases raises some interesting issues. Perhaps most important, companies are not required to (and rarely do) furnish their investors with details about a given program's structure, execution method, number of shares repurchased, or even its duration. Policy regulators (and corporate executives as well) should consider some of the benefits provided by other systems, notably Canada's, which provide greater transparency and more guidelines for the repurchase process.     

The timing of financing decisions: An examination of the correlation in financing waves

Why do corporate financing events occur in waves? We challenge recent evidence of the importance of valuation cycles in driving financing waves by documenting that the aggregate pattern of stock repurchases mirrors that of equity issuance and mergers, despite repurchases involving an opposite transaction. We then show that trends in financing decisions result from differing responses to the same economic stimulus: growth in GDP. Specifically, economic expansion reduces the cost of equity relative to the cost of debt, inducing firms to issue equity, and increases cash flow and also causes varying degrees of uncertainty, increasing stock repurchases. We document similar trends and provide similar motivation for merger waves.     

Have changing takeover defense rules and strategies entrenched management and damaged shareholders? The case of defeated takeover bids

Using the Delaware Supreme Court's Time-Warner decision of July 1989 as a focal point, we study defeated takeover bids before and after July 1989 to assess the direct effects of stronger takeover impediments on takeover defense tactics used to defeat bids and the resulting shareholder wealth outcomes and managerial turnover. We find that firms that defeated takeover bids after July 1989 shifted away from the use of active takeover defenses (repurchases, special dividends, greenmail, and leverage increases). Nevertheless, shareholders of firms that defeat a takeover experienced slightly better wealth outcomes in the 1990s than in the 1980s. We also find increased managerial turnover rates after defeating a takeover bid post Time-Warner, suggesting that managers that defeat hostile takeover bids did not become more entrenched due to greater takeover impediments relative to prior years.     

Executive compensation, share repurchases and investment expenditures: econometric evidence from US firms

This paper modeled the dynamic inter-relationships between average salary, bonus, and stock options granted to top executives of 700 US firms using a merged ExecuComp and Compustat database. The effects of stock options granted and exercised on firms’ share repurchases and research and development and investment expenditures were investigated, taking into account simultaneity and distributional misspecification aspects. First, firms’ total assets, intangible assets, market-to-book value, and share repurchases were positively associated with the values of stock options granted. Second, stock options exercised in the previous year were significant predictors of share repurchases indicating that firms avoided dilution of earnings per share. Third, share repurchases and stock options granted were negatively associated with expenditures on research and development and long-term investments. Overall, the results suggest that high levels of stock options granted to executives and share repurchases are unlikely to have beneficial effects for raising future productivity.     

Flexibility in share repurchases: Evidence from UK

Although firms cite flexibility as important when repurchasing shares, we know little about how or why firms vary repurchases. We use an extensive sample of daily repurchase transactions from the United Kingdom to investigate how the number of repurchase days and volumes of shares repurchased change based on several known motivations. We find that stock price changes, liquidity, leverage, takeover activity and earnings per share targets impact share repurchasing patterns. Further, we compare actual repurchases to alternative share accumulation strategies and find that firms utilize flexibility without paying higher costs.     

Defensive Mechanisms and Managerial Discretion

We study a model where firms may possess free cash flow and takeovers may be disruptive. We show that the possibility of a takeover, combined with defensive mechanisms and the ability to pay greenmail, can solve the free cash flow problem in an efficient way. The payment of greenmail reveals information that generates a stock price decline that exceeds the value of the greenmail payment, even though the payment of greenmail is value maximizing. Optimal defensive measures limit takeover attempts if the target stock price is too low. We also provide cross-sectional implications of the analysis.     

Stock price behavior surrounding stock repurchase announcements: Evidence from Japan

This paper examines stock price behavior surrounding announcements of stock repurchases made by Japanese firms from 1995 to 1998. Our analysis shows that, much as in the case of the U.S. markets, stock prices in Japan go up in response to stock repurchase announcements. We also find that there is no significant difference between the market reaction to the announcement for intention of repurchase execution and the market reaction to the announcement of an article alteration to allow stock repurchases. On the other hand, there is a significant difference in the pre-announcement period returns motivating these two announcements. While a large decline in stock price will motivate a firm to execute a stock repurchase, a smaller price decline will motivate a firm to merely alter its articles of association to allow future repurchases.     

Takeover Defences and IPO Firm Value in the Netherlands

The central question of this study involves the relation between the use of takeover defences and IPO firm value. We report that management frequently uses takeover defences before taking the firm public. The use of takeover defences is primarily motivated by managerial entrenchment. IPO investors anticipate potential conflict of interests with management and reduce the price they pay for the IPO shares if takeover defences are adopted. Although managers internalise this cost of takeover defences to the degree they own pre‐IPO stock, they are likely to gain through private control benefits. Non‐management pre‐IPO owners lose. Their shares are worth less, but different from managers, they do not get offsetting private control benefits. We infer that managers use takeover defences to protect private control benefits at non‐management pre‐IPO owners’ expense.     

Intraindustry Effects of Bank Stock Repurchases

Bank stock repurchases have become increasingly popular over time. Because of the unique capital requirements and regulatory constraints on the use of bank funds, the intraindustry effects of bank stock repurchases may differ from intraindustry effects of stock repurchases by other firms. We find that bank stock repurchases result in a positive and significant valuation effect for the repurchasing banks. Moreover, we find positive significant intraindustry effects of bank stock repurchases, unlike previous research by Hertzel on firms from numerous industries that found no evidence of intraindustry effects in response to stock repurchases. We attribute the difference in results to the unique characteristics of the banking industry, which results in a less ambiguous signal emitted from the stock repurchase announcement. In addition, we find that the intraindustry effects are more favorable when the valuation effect for the repurchasing bank is more favorable. This implies that the degree of signal to the industry is conditioned on the degree of signal about the bank that is repurchasing its shares. Furthermore, intraindustry effects are more favorable when the capital position of rival banks is high, when the proportion of residential loans of rival banks is low, and when the announcing bank is a money center bank.     

The influence of earnings management conducted through the use of accretive stock repurchases on audit fees

This study investigates whether auditor perceptions of risk are affected by accretive stock repurchases, which prior research has suggested is a form of earnings management. We argue that auditors are likely to view earnings management conducted through the use of accretive stock repurchases as a signal of increased risk, leading to higher audit fees. Consistent with our hypothesis, we find evidence of a positive and significant association between the use of accretive stock repurchases as an earnings management technique and audit fees. The results suggest that audit fees are 6.0% higher when accretive stock repurchases are used to manage earnings, which corresponds to an audit fee that is approximately $107,000 higher for the average firm-year observation in our sample.     

The Takeover Deterrent Effect of Open Market Share Repurchases

This paper examines whether open market share repurchases deter takeovers. We model pre‐repurchase takeover probability as a latent variable and examine its impact on the firm's decision to repurchase shares. Given specification tests reject the Tobit model, we turn to the censored quantile regression method of Powell (1986, Journal of Econometrics 32, 143–155). We find a significantly positive relation between open market share repurchases and takeover probability, and we reconcile empirical findings in previous studies that contradict predictions. Repurchase activity is inversely related to firm size, consistent with smaller firms having greater information asymmetry, and is related to temporary, but not permanent, cash flows.
