This paper hypothesizes that hot convertible debt windows represent periods with lower convertible debt-related financing costs. Supporting this premise, we find that the stock price impact of Western European convertible debt announcements is significantly less negative during hot convertible debt windows. Importantly, this result holds while controlling for equity and straight debt issuance volumes and for macroeconomic conditions. In addition, stockholders are less sensitive to issuer- and issue-specific financing costs during hot convertible debt markets. Overall, these findings indicate that hot convertible debt markets represent windows of opportunity for convertible debt issuance. Firms with high idiosyncratic financing costs act accordingly by timing their convertible debt offering during a hot market.

We examine the influence of corporate governance quality on firms' choice between convertible debt, straight debt, and equity using a Western European sample of security offerings made between 2000 and 2010. We find that weaker firm-specific and country-specific corporate governance quality increases firms' likelihood of issuing convertible debt instead of straight debt and common equity. We also find that stockholder reactions to convertible debt announcements are more favorable for firms with weaker corporate governance. Our results suggest that corporate governance quality is a significant security choice determinant, with firms using convertible debt as a substitute for high quality governance mechanisms.

We review the literature on the issuance motives, shareholder wealth effects, and design of convertible bonds. Empirical studies on convertible debt issuance mainly focus on testing the predictions of four traditional theoretical models based on convertibles' potential to mitigate agency or adverse selection costs, and obtain mixed evidence. Recent studies on shareholder wealth effects of convertible bond issues highlight the need to control for arbitrage-related short selling and post-issuance risk changes. Studies on the determinants of convertible bond design uncover earnings management, as well as catering incentives to convertible arbitrage funds, as important determinants of innovations in convertible bond characteristics. Overall, our review indicates that recent empirical research on convertible debt provides valuable insights into issue motives and determinants of financial innovations, but also considers the broader question of how investor demand characteristics impact corporate finance decisions. We conclude with an overview of potential research questions to be addressed by future research on hybrid securities.

Over recent years, a substantial fraction of US convertible bond issues have been combined with a stock repurchase. This paper explores the motivations for these combined transactions. We argue that convertible debt issuers repurchase their stock to facilitate arbitrage-related short selling. In line with this prediction, we show that convertibles combined with a stock repurchase are associated with lower offering discounts, lower stock price pressure, higher expected hedging demand, and lower issue-date short selling than uncombined issues. We also find that convertible arbitrage strategies explain both the size and the speed of execution of the stock repurchases.

Traditional seasoned equity offerings (SEOs) elicit short selling from traders trying to increase offering discounts. Such short selling is more difficult for shelf offerings because the time between their announcement and issuance tends to be shorter. We predict and find that firms with higher short-selling potential (SSP) are more likely to choose shelf over traditional SEOs. This result is robust to alternative proxies for SSP and other sensitivity tests. Further analysis suggests that shelf issuers aim to mitigate the threat of manipulative short selling. Our findings add to a growing literature showing that short selling has a real impact on corporate finance decisions.

We examine whether corporate social responsibility (CSR) creates value for seasoned equity issuers. Using a sample of seasoned equity offerings (SEOs) by U.S. companies between 2004 and 2013, we find a positive association between CSR performance and the stock price reaction to SEO announcements. Surprisingly, however, further tests reveal that seasoned equity issuers with high CSR scores tend to have higher post-SEO increases in cash holdings, and lower investments in real assets, than issuers with low CSR scores. Moreover, high-CSR issuers have worse post-SEO operating and stock price performance than low-CSR issuers. Together, our findings suggest that high CSR scores mislead shareholders into attributing value-increasing motives to seasoned equity issues.

Announcements of stock-financed mergers and acquisitions (M&As) may attract short selling of bidder shares by merger arbitrageurs. We hypothesize that bidders with higher short-selling potential include a higher proportion of cash in their M&A payments to mitigate stock price declines resulting from arbitrage short sales. Consistent with this hypothesis, we find that the ex ante net lending supply of bidder shares has a positive impact on the percentage of cash in public target payments. Further tests, including a placebo analysis of public-to-private deals and an analysis of expected price pressure proxies, corroborate the impact of anticipated arbitrage-related price pressure on payment choice.

We survey institutional investors about their role in capital structure decisions and views on capital structure theories. Over 82% of investors believe they influence corporate capital structure decisions, especially for smaller, younger, and more financially constrained firms. Unlike corporate managers, investors consider agency costs of free cash flow important drivers of capital structure. Investors' responses also support pecking order and market timing theories. Most investors find financial constraints important, with components of the Kaplan–Zingales and Whited–Wu indexes dominating other proxies. Overall, our findings suggest a first-order impact of investor preferences on capital structure decisions.

U.S. and Japanese firms dominate global convertible bond issuance. Previous research documents more favorable convertible bond announcement effects in Japan than in the U.S. and other developed countries. Using a global sample of convertible bonds issued from 1982 to 2012, we find that the more favorable announcement effects of Japanese convertibles are driven by their stated uses of proceeds. Japanese convertibles more often include capital expenditure as an intended use, while U.S. firms tend to mention general purposes to motivate their offering. Our findings illustrate the value to firms of being more explicit when disclosing the intended use of proceeds of security offerings.

While convertible offerings announced between 1984 and 1999 induce average abnormal stock returns of −1.69%, convertible announcement effects over the period 2000–2008 are more than twice as negative (−4.59%). We hypothesize that this evolution is attributable to a shift in the convertible bond investor base from long-only investors towards convertible arbitrage funds. These funds buy convertibles and short the underlying stocks, causing downward price pressure. Consistent with this hypothesis, we find that the differences in announcement returns between the Traditional Investor period (1984–1999) and the Arbitrage period (2000–September 2008) disappear when controlling for arbitrage-induced short selling associated with a range of hedging strategies. Post-issuance stock returns are also in line with the arbitrage explanation. Average announcement effects of convertibles issued during the Global Financial Crisis are even more negative (−9.12%), due to a combination of short-selling price pressure and issuer, issue, and macroeconomic characteristics associated with these offerings.
