The first study (Part 2) explores the role of the firm’s product market competition by assessing the survival times of IPOs in the aftermarket. To test the possible relationship, a prediction model using factors that characterize the firm’s product market competition together with firm-, deal- and market-related variables is employed. My results suggest that industry concentration, the degree of competitive interaction among companies and the industry’s entry rate all significantly affect survival time. The second and third study (Parts 3 and 4) focus on the intra-industry effects of IPOs. Part 3 analyzes the valuation effects of IPOs on listed industry competitors and provides evidence that competitors exhibit a negative price reaction to the filing and completion of an IPO in their industry. This reaction is attributed to a competitive effect associated with an IPO. I further find that the competitive effect upon a completed IPO is negatively related to the toughness of the product market competition. IPOs in industries that have higher industry concentration, a lower degree of strategic interaction and lower industry demand uncertainty exhibit a stronger competitive effect on their rivals. Part 4 analyzes the valuation effect of withdrawn IPOs on listed industry competitors. When controlling for confounding events, the competitor portfolio does not, on average, show a significant reaction. However, a cross-sectional analysis, using variables that account for the market environment as well as industry, deal and company characteristics, shows that market variables have a strong impact on competitors’ responses. Furthermore, industry concentration is found to have a significantly negative impact and the filing firm’s financial leverage to have a significantly positive impact on competitors’ abnormal returns. This finding is consistent with the theory that the ex-ante risk of withdrawal of the IPO filing affects competitors’ reactions. These results provide evidence for the existence of an intra-industry effect of withdrawn IPOs. VI Abstract in German Abstract in German Diese Dissertation befasst sich mit zwei Aspekten von Börsengängen: der Überlebensdauer an der Börse und intra-Industrie Effekten. In der ersten Studie (Teil 2), wird der Einfluss der Wettbewerbssituation des Unternehmens auf seine Überlebensdauer an der Börse untersucht. Dabei wird ein Vorhersagemodell, welches Faktoren beinhaltet, die den Wettbewerb sowie Firmen-, Transaktions- und Marktcharakteristiken abbilden verwendet. Die Resultate zeigen, dass die Industriekonzentration, das Maß der Wettbewerbsinteraktion und das Wachstum der Unternehmensanzahl einen signifikanten Einfluss auf die Überlebensdauer haben. Die zweite und dritte Studie (Teile 3 und 4) befassen sich mit intra-Industrie Effekten von Börsengängen. Teil 3 analysiert den Bewertungseffekt eines Börsengangs auf gelistete Wettbewerber und zeigt, dass diese nach der Ankündigung und Durchführung eines Börsengangs in ihrer Industrie eine negative Reaktion aufweisen. Die Reaktion ist auf einen Wettbewerbseffekt des Börsengangs zurückzuführen. Dieser Wettbewerbseffekt ist negativ mit der Wettbewerbsintensität in der Industrie korreliert. Börsengänge in Industrien mit einer hohen Industriekonzentration, einem geringen Maß an Wettbewerbsinteraktion und geringer Nachfrageunsicherheit weisen einen stärkeren Wettbewerbseffekt auf. Teil 4 analysiert den Bewertungseffekt eines zurückgezogenen Börsengangs auf gelistete Wettbewerber. Wenn man irritierende Vorfälle beachtet, zeigt sich, dass das Wettbewerberportfolio keine signifikante Reaktion aufweist. Eine Regressionsanalyse, welche Variablen für das Marktumfeld, die Industrie, die Transaktion und das Unternehmen beinhaltet, zeigt, dass die Marktstimmung einen großen Einfluss auf die Wettbewerberreaktion hat. Außerdem hat die Industriekonzentration einen signifikant negativen Einfluss und der Verschuldungsgrad des Unternehmens einen signifikant positiven Einfluss auf die Wettbewerberreaktion. Dieses Ergebnis unterstützt die Theorie, dass das VorabRisiko eines Börsengangrückzugs einen Einfluss auf die Wettbewerberreaktion hat. Die Resultate weisen daher auf einen intra-Industrie Effekt von zurückgezogenen Börsengängen hin. Introduction -1- 1 Introduction 1.1 Motivation The Initial Public Offering (IPO) is one of the most significant steps in the company’s life cycle and one that probably triggers the most public attention. The immense media coverage of prominent IPOs, such as Groupon’s $700 million offering in 2011 and Facebook’s $16 billion IPO in 2012, demonstrates the extensive importance of such events. For the issuing company and the accompanying investment banks, a successful IPO is crucial because a very large amount of money is involved. Yet, an IPO is not simply a firm-related event; it also affects and it is affected by other factors including investors, competitors and further related financial market members. For these groups, it is important to understand the complex dynamics and effects that accompany an IPO. In this dissertation, I thus provide further insights into these dynamics by focusing on two topics concerning a company’s IPO: the survivability of the IPO in the aftermarket and the intra-industry effects of the IPO. For a company, going public means significant changes in terms of legal requirements, disclosure, public attention and, most importantly, access to the capital market. These changes and the IPO preparations that are necessary are costly. It is thus of great interest for companies to receive a satisfactory valuation at the time of the IPO. For investors, the performance of the IPO is of greatest interest. As a consequence, the vast majority of research in the academic finance literature focuses on the valuation and performance of IPOs. This stream of research is focused on solving the well-known IPO puzzles, namely underpricing and the long-run underperformance of new issues. Underpricing refers to the phenomenon that IPOs experience huge returns in the initial trading days and explores why issuing companies leave that money on the table. This puzzle has first been observed by Ibbotson (1975), with many subsequent studies attempting to explain this observation. Most prominent are theories that assume a relationship between underpricing and information asymmetry, such as Rock’s (1986) “winner’s curse theory”, Beatty and Ritter (1986), Baron (1982) and Benveniste and Spindt (1989). -2- Introduction However, the studies have thus far been unable to fully explain the puzzle but confirm the existence and persistence of underpricing in different countries (e.g., Loughran, Ritter and Rydqvist, 1994). The second puzzle refers to the underperformance of IPO companies in the initial years compared with size and book-to-market matched peers and has also been well documented in the literature (see Ritter, 1991; Ritter and Welch, 2002). As in the case of underpricing, previous studies have failed to provide a satisfactory explanation for the performance puzzle. However, an IPO is not just an isolated firm-specific event. A central factor thereby is the competitive environment, which includes competitors and competition in the product market. Several studies have described the important interaction of an IPO with its competitive environment. For instance, Chemmanur, He and Nandy (2010) show that product market competition is a significant factor in a firm’s decision to go public. Furthermore, Chod and Lyandres (2011) as well as Chemmanur and He (2011) find that competition in the product market also significantly influences the company’s post-IPO performance. These studies therefore suggest that product market competition significantly affects the dynamics of an IPO. By contrast, the studies by Akhigbe, Borde and Whyte (2003) and Hsu, Reed and Rocholl (2010) suggest that an IPO also affects the competitive environment. These two studies examine competitors’ responses to an IPO in their industries and find evidence for a competitive and an information effect of an IPO on industry competitors. The competitive effect arises because the IPO affects the competitive balance in the industry. The information effect refers to the release of private information about the industry from the IPO. These studies show that together with firm-specific and market-related considerations, the competitive environment influences the IPO. In return, the IPO also affects the competitive environment. Therefore, an IPO should not be seen as firm-specific but in interaction with the company’s environment. To study this interaction, this dissertation explores how the competitive environment influences the IPO and vice versa. In particular, it focuses on the influence of product market Introduction -3- competition on the survival time of an IPO in the aftermarket (Part 2) and the effect of an IPO on competitors (Parts 3 and 4). Survival time represents the time a newly listed company survives in the capital market. This is a basic but crucial way of performance measurement. In this context, the company’s survival ends when it is delisted from the stock exchange for negative reasons. Studying the survival times of new firms in the aftermarket has gained more interest as the number of defaulting companies has been increasing over the last decades as documented by Fama and French (2004). According to the authors, this has occurred because of the changing characteristics of newly listed firms. The supply of capital has increased over recent years, leading to a decline in the required returns and consequently to lower costs of capital. Lower costs of capital turn the net present values of more firms that have low profitability levels but high growth expectations positive. As a result, the number of new risky firms increases, as do delisting rates. Thus far, few studies investigate the survival times of IPO companies. Hensler, Rutherford and Springer (1997) are the first to connect the company’s survival time with factors at the time of the IPO. In a more recent article, Demers and Joos (2007) study IPO survival times using firm-specific as well as market- and dealrelated variables.1 The research on IPO survival is strongly related to that on firm survival in general. Traditional models of bankruptcy prediction such as Altman’s (1968) Z-score focus on accounting variables. It has been shown by Shumway (2001) that these static models are outperformed by dynamic hazard models when predicting firm survival and that including market-driven variables strongly increases the default predictability.2 Including product market competition thus expands the existing literature on IPO survival. The second topic of this dissertation are the intra-industry effects of IPOs. Although the major impact of an IPO relates to the issuing company, when a company goes public, the impact of the IPO is not limited to the company alone. For competitors 1 Other studies explore the survival of internet IPOs (Kauffman and Wang, 2003; van der Goot, van Giersbergen, and Botman, 2009), the survival of penny-stock IPOs (Bradley, Cooney, Dolvin and Jordan, 2006; Carpentier and Suret, 2011) and the influence of underwriters (Jain and Kini, 1999) and auditors (Weber and Willenborg, 2003; Willenborg and McKeown, 2001) on survival. 2 Chava and Jarrow (2004) find that including accounting variables adds little predictive power when market-driven variables are already included in the prediction model. -4- Introduction and investors, it is thus important to understand the impact of the IPO’s intra-industry effect. For example, Ritter and Welch (2002) notice that an IPO affects the company’s relations with its customers, creditors and suppliers. Going public is a strong commitment and the result of a successful company strategy. Therefore, being public increases the company’s reputation and credibility in the relation with these stakeholders. Most importantly, the IPO brings fresh capital into the company. These changes have an impact on the company’s competitive situation, and therefore, are relevant for competitors as well. Empirical support for this assumption comes from Akhigbe et al. (2003) and Hsu et al. (2010), who study the intra-industry effects of IPOs. Additionally, an IPO affects competitors not only by influencing product market competition, but also through an information effect. Previous studies have shown that corporate events provide an information signal to competitors. For instance, Lang and Stulz (1992), Cheng and McDonald (1996) as well as Ferris, Jayaraman and Makhija (1997) all show that bankruptcy announcements have a significant information effect on competitors. Akhigbe and Madura (1999) report a significant information effect of acquisition announcements in an industry. Further, the studies by Akhigbe et al. (2003) and Cotei and Farhat (2011) find empirical evidence for the existence of an IPO’s information effect. 1.2 Research Ideas Although the interaction of the IPO with product market competition and competitors is an under-researched topic, it is important for investors and managers, both of the issuing firm and of competitors, to understand the driving forces behind the dynamics of an IPO. These insights should help investors and senior management assess the risks and opportunities associated with an IPO. The first topic in this dissertation thus explores the question of whether the survivability of a newly listed company in the aftermarket is influenced by product market competition. In the context of interaction, this question examines the influence of product market competition on the IPO. This research is motivated by the findings from Chemmanur and He (2011), Chemmanur et al. (2010) and Chod and Lyandres (2011), who show the significant impact of product market competition Introduction -5- on the firm’s decision to go public and its post-IPO performance. Furthermore, Hou and Robinson (2006) find that product market competition is a significant risk factor in explaining average stock returns. Taking the firm’s product market competition into account when explaining the survivability of IPO companies adds a further dimension to previous research, which has only explored firm-, deal- and market-related factors. To my best knowledge, no study so far has taken into consideration the company’s product market competition when studying IPO survival.3 Including product market competition makes sense though because every firm faces competition from its competitors in the product market. As product market competition differs between industries, it is easier, given the same financial endowment, to survive in one industry while it might be more difficult in another industry. It is thus the company’s success in its product market that ultimately determines its financial success and therefore its stock performance and survival in the financial market. Therefore, Part 2 of this dissertation is dedicated to answering whether product market competition does have an effect on the survival time of an IPO firm with the following two research questions: Do companies operating in a tough competitive environment have a shorter survival time in the aftermarket? Do companies operating in a weak competitive environment have a longer survival time in the aftermarket? The second topic focuses on how an IPO affects industry competitors. In the context of interaction, this topic examines the influence of the IPO on the competitive environment. The starting point is that an IPO is not only a firm-specific event but that it influences competitors as well. This influence can be caused either by an information effect or by a competitive effect as previous studies have shown 3 Demers and Joos (2007) employ the gross profit margin to account for production efficiencies, brand names, pricing power and competitive conditions in a firm’s product market. Li and Zhou (2006) and Seguin and Smoller (1997) control for six major industries in their studies. The recent studies by Carpentier and Suret (2011) and Wagner and Cockburn (2010) also control for industry affiliation. -6- Introduction (Akhigbe et al., 2003). Hsu et al. (2010), Chod and Lyandres (2011) and Chemmanur and He (2011) all find evidence that the competitive effect is caused by a competitive advantage of the issuing firm, which affects the competitive balance in the industry and causes an adverse effect on rival companies. This leads to the question of whether the degree to which IPO firms are able to gain a competitive advantage depends on the existing competition in the product market. To give insights into this question, Part 3 focuses on the interaction between the IPO’s competitive effect and the competitive environment with the following research questions: Is the IPO’s competitive effect stronger in industries with a weak competitive environment? Is the IPO’s competitive effect weaker in industries with a tough competitive environment? Given that the previous research questions explore the intra-industry effect of a successful IPO event (either an IPO filing or a completion), an ensuing question is how a negative IPO event, that is the withdrawal of an IPO filing, affects industry competitors. In the context of interaction, this topic also examines how an IPO influences the competitive environment. The withdrawal can have only firm-specific implications or it can trigger an intra-industry effect, caused by an information effect and/or a competitive effect. Part 4 therefore examines the possible intra-industry effects of withdrawn IPOs and focuses on the following two research questions: Do withdrawn IPOs have an intra-industry effect? If withdrawn IPOs have an industry wide impact, which factors have an influence on the intra-industry effect? To summarize, this dissertation investigates whether product market competition influences the survival time of an IPO, what role product market competition plays Introduction -7- for the intra-industry effects of IPOs and whether withdrawn IPOs have an intraindustry effect (and if so, which factors influence this effect). The dissertation thus provides insights into the interaction of the IPO with the competitive environment to better understand the implications for the dynamics upon an IPO. To answer these research questions, I carry out an empirical analysis using IPO data from the US, which is by far the largest capital market. 1.3 Course of the Analysis The remainder of this dissertation is structured as follows. Part 2 explores the question whether product market competition influences the survival time of newly listed firms in the aftermarket. Part 3 focuses on how the IPO affects the competitive environment by looking at the intra-industry effects of IPOs and the role of product market competition. The analysis in Part 3 leads to the research question in Part 4: What is the effect of withdrawn IPOs on industry competitors? Finally, Part 5 summarizes and concludes the overall findings of this dissertation. The empirical analysis starts in Part 2, which focuses on the role of the firm’s product market competition by assessing the survival times of IPOs in the aftermarket. To test the possible relationship, a prediction model using factors that characterize the firm’s product market competition together with firm-, deal- and market-related variables is employed. For this analysis, a parametric log-logistic model and the Cox (1972) proportional hazard model are applied. The results suggest that product market competition significantly affects survival time. Further, using different baseline hazard functions does not change the results. The analysis using a logit discrete response model also confirms these findings. The results show that product market competition is a further dimension that influences the survival of newly listed firms in the aftermarket. These insights should help investors assess the risk structure of a firm that is going public. The analysis continues by looking at the intra-industry effects of IPOs in Part 3. The study focuses on the competitive effect of an IPO on industry competitors. I hypothesize that the degree to which a newly listed company benefits from going -8- Introduction public depends on the competition in the product market. This implies that the benefits of going public are higher when competition in the industry is rather weak whereas the benefits of going public are lower when competition in the industry is rather tough. To test these hypotheses, I apply the event-study methodology in order to analyze competitors’ abnormal returns around a successful IPO in their industries. I find that industry competitors yield negative abnormal returns in response to a filing or completed IPO in their industries. Analyzing the competitors’ abnormal returns, the results show that product market competition significantly influences competitors’ abnormal returns. In other words, the weaker the competitive environment, the stronger is the IPO’s competitive effect. I further find that IPOs in industries with a tough competitive environment do not trigger a significant competitors’ response. These findings have important implications for private firms in their decision to go public. When operating in an industry that has a weak competitive environment, going public is associated with more benefits. The presented results should help investors of competing firms assess the risks associated with an IPO in the industry. Part 4 continues with the analysis of the intra-industry effects of IPOs by exploring the possible impact of a withdrawn IPO on industry competitors. I focus on the information effect of a withdrawn IPO. The underlying assumption is that the withdrawal of an IPO is a signal of a worsening industry outlook. This signal would be stronger when the withdrawal is less anticipated. I therefore identify such IPO withdrawals with a strong information effect using the ex-ante risk of withdrawal. In a first step, I use the event-study methodology in order to get an insight whether a withdrawn IPO is merely a firm-specific event or has industry-wide implications. In a second step, I analyze competitors’ abnormal returns around a withdrawn IPO in the industry to assess which factors have an impact on the competitors’ reaction. The analysis shows that on average, there is no observable competitors’ reaction around the withdrawal of an IPO in the industry. However, further analysis finds that market sentiment, industry concentration and the issuing firm’s financial leverage all have a significant impact on the competitors’ reaction. While the impact of industry concentration is negative, the impact from leverage is positive. These findings are Introduction -9- consistent with the theory that IPO filings with a low ex-ante risk of withdrawal have a strong information effect when withdrawn. Overall, the results provide evidence for the existence of an intra-industry effect of withdrawn IPOs. - 10 - Introduction References Akhigbe, A. & Madura, J. (1999).

To test the possible relationship, a prediction model using factors characterizing the firm’s product market competition together with firm-, deal- and market-related variables is employed. For this analysis a parametric log-logistic model and the Cox proportional hazard model are applied. My results suggest that industry concentration, the degree of competitive interaction among companies and the industry’s entry rate significantly affect the survival time. For industry demand uncertainty and the market share the results are not statistically significant. Various robustness tests confirm these findings. The results contribute to the existing literature by showing the important role of taking the firm’s product market competition into account when predicting the IPO’s survival time in the aftermarket. 4 This study has been published in the Corporate Finance biz Journal.

The Survivability of Initial Public Offerings - 15 - 2.1 Introduction When a new firm enters the financial market, the Initial Public Offering (IPO) is accompanied by expectations but also by uncertainty. For investors it is essential to evaluate the IPO’s potential and risk before investing. One dimension of the IPO’s aftermarket performance is the expected survival time in the financial market which is the topic of this study. A delisting due to negative reasons from the market is mostly accompanied with serious financial distress or even bankruptcy. Therefore, the survival time is a measure of performance, not only for investors but also for further stakeholders like debtees, banks, employees or suppliers. Empirical evidence shows the critical phase of a new firm in the market is the time shortly after going public (Hensler, Rutherford and Springer, 1997 or Demers and Joos, 2007). Factors at the time of the IPO are expected to provide valuable insights on the expected survival time. Starting with Hensler et al. (1997), prior literature has already connected IPO survival with factors upon the IPO (also see Demers and Joos, 2007; Jain and Kini, 2008; van der Goot, van Giersbergen and Botman, 2009). These studies identify variables which can be categorized into three groups: firm specific, market- and deal-related variables. Prior studies only focus on the IPO company itself and on relations of the company with the financial market and intermediaries. However, these studies omit the company’s product market environment when studying IPO survival.5 Firm-specific factors like leverage or profitability should be interpreted together with the competitive environment. Recent studies show that product market competition plays a significant role for the firm’s decision to go public and also for the post-IPO performance (see Chemmanur, He and Nandy, 2010; Chod and Lyandres, 2011; Chemmanur and He, 2011). Every firm faces competition from its rivals in the product market. The degree in which a firm succeeds in the product market competition determines the chances of survival and financial success. As product 5 Demers and Joos (2007) employ the gross profit margin to account for production efficiencies, brand names, pricing power and competitive conditions in a firm’s product market. Li and Zhou (2006) and Seguin and Smoller (1997) control for six major industries in their studies. The recent studies by Carpentier and Suret (2011) and Wagner and Cockburn (2010) also only control for industry affiliation. - 16 - The Survivability of Initial Public Offerings market competition differs between industries, it is easier for some companies to be successful in the product market whereas others might fail given the same financial endowment. This study is an attempt to connect the expected survival time of an IPO with product market competition. 2.2 Related Literature 2.2.1 IPO Survival The literature on the survival of IPOs origins in the literature on bankruptcy prediction. Traditional models like Altman’s Z-score (Altman, 1968) or Ohlson’s Oscore (Ohlson, 1980) focus on accounting variables. Shumway (2001) shows that these static models are outperformed by a dynamic hazard model to predict firm survival. Shumway further adds market-related variables to his model and finds a strong increase in the default predictability (see also Chava and Jarrow, 2004 and Beaver, McNichols and Rhie, 2005). Only a limited number of studies deal with the survival time of IPOs so far. Fama and French (2004) document that over the last decades, more firms characterized by low profit/high growth went public which has decreased the average survival time of an IPO significantly. The literature on IPO survival is an attempt to discover the reasons why a new firm actually fails in the market. A comprehensive study on the survival predictability of IPOs is conducted by Demers and Joos (2007). The authors use accounting information, deal-related variables as well as variables accounting for the role of information intermediaries to study the factors which influence IPO survival in a non-tech and a high-tech sample. Hensler et al. (1997) use firm-specific as well as market-related factors to study the effect on the survival time of firms going public. Their study is the first to link the IPO’s time-to-failure to factors at the time of the IPO. Using the same approach as Hensler et al., van der Goot et al. (2009) focus on the determinants of the survival of internet IPOs. Internet IPOs which have been dominating the IPO market during the dotcom bubble in the late 1990s exhibit a far higher hazard rate than traditional IPOs.6 6 For the survival of internet IPOs see also Kauffman and Wang (2003). The Survivability of Initial Public Offerings - 17 - Carpentier and Suret (2011) as well as Bradley, Cooney, Dolvin and Jordan (2006) study the survival of penny stock IPOs.7 Both studies report a significantly higher hazard rate for penny stock IPOs than for ordinary IPOs. Wagner and Cockburn (2010) study the role of intellectual property rights for “new economy” firm survival. The authors find that the number of patents positively influences firm survival in a sample of internet IPOs going public at NASDAQ in the bubble period of 1998 to 2001. Further studies focus on the role of financial intermediaries. Weber and Willenborg (2003) as well as Willenborg and McKeown (2001) report the positive influence of auditors in assuring a new firm’s quality and therefore the survival probability. Jain and Kini (1999) study the role of underwriter reputation, finding a positive relation between reputation and aftermarket performance of IPO companies. Moreover, a positive influence on IPO survival is associated with venture backing (Jain and Kini, 2000). These studies demonstrate that financial intermediaries provide valuable information about the firm’s quality. 2.2.2 Product Market Competition Prior literature has already found that product market competition affects the firm performance. Earlier studies focus on the connection between industry concentration and accounting profitability. Cowling and Waterson (1976) find that industry concentration is positively related to the price-cost margin and Qualls (1972) shows that the positive relation is also true for further profit margins (also see Bain, 1951 or Mann, 1966). More recent studies show that the competitive environment also affects stock returns. Hou and Robinson (2006) find that firms in more concentrated industries earn lower returns after controlling for common risk factors. Supporting evidence further comes from Hashsem (2010) who studies an UK sample. In an ensuing study, Sharma (2011) confirms the influence of industry concentration and also shows that firms with relatively low product substitutability and a low market size earn lower stock returns as well. A possible explanation for this empirical observation comes from Gaspar and Massa (2006) who find that industry 7 There exists no clear cut definition for the term „penny stock IPO“. Generally it refers to an initial public offering with an offering price below some threshold value. In the US, e.g. stocks below an offering price of 5 USD are considered as penny stocks. - 18 - The Survivability of Initial Public Offerings concentration is also connected to idiosyncratic volatility. Firms in industries with a higher degree of concentration exhibit lower idiosyncratic volatility. In the case of an IPO, product market competition is also found to have a significant influence. Studying the decision to go public of a large sample of private US manufacturing firms, Chemmanur et al. (2010) find that product market competition is a significant determinant in the going public decision. Product market competition also affects the post-IPO performance. Chod and Lyandres (2011) show that the strategic benefit of being public is associated with product market competition. The authors find that going public is accompanied with an increase in the IPO firm’s market share and this increase is influenced by product market competition. Chemmanur and He (2011) report further evidence that going public is associated with an increase in the product market share after the IPO and the role of product market competition. Additionally, the authors report a significant relationship between factors from the product market competition and operating performance after the IPO. The purpose of this study is to combine the literature on IPO survival with the literature on product market competition. The literature review suggests that the competitive environment is a significant risk factor which influences firm performance. So far, this risk factor has not been employed in explaining the survival time of IPOs. My study is an attempt to close this research gap. 2.3 Hypothesis Development One possible indicator for the industry’s competitive environment is industry concentration. This is an often used measure to account for the industry’s competitiveness, both in academic literature and practice.8 It is assumed that the more concentrated an industry, the weaker is the competition among the firms. Economic theory suggests that competition ranges from perfect competition over an oligopoly to 8 See for example Bikker and Haaf (2002) who find evidence of the adverse effect of concentration on competition for the banking industry or Lang and Stulz (1992), Chevalier (1995), Sundaram, John and John (1996) or Akhigbe, Borde and Whyte (2003) who use industry concentration to control for competition in their studies on the intra-industry effect of firm announcements. Also see Tirole (1988) for a theoretical discussion. The industry concentration is also a crucial factor in decisions by the US Department of Justice or the European Commission on merger and acquisition cases. The Survivability of Initial Public Offerings - 19 - a monopoly with decreasing “toughness” of competition. Industries with low concentration exhibit characteristics of perfect competition whereas industries with high concentration exhibit characteristics of an oligopoly. For the IPO survival time, I expect that chances of survival are higher for IPOs facing competition in more concentrated industries, leading to the first hypothesis. H1: The industry concentration has a positive influence on the IPO’s survival time. As suggested by Raith (2003) as well as Sharma (2011), industry concentration does not capture all dimensions of product market competition. I therefore use several further factors to create a more comprehensive picture of product market competition. An alternative measure for the industry’s competitive environment is the way a company responds to strategic choices of its competitors. This is represented by the degree of competitive interaction and can either be in “strategic substitutes” or in “strategic complements” according to the oligopoly literature (Bulow, Geanakoplos and Klemperer, 1985). The companies’ interaction in an industry, i.e. whether they take their decision rather dependent or independent of competitors’ decisions, is a further characteristic of product market competition. More interaction among the firms increases competition, making the competitive environment tougher. I therefore expect that survival is more difficult in industries in which the competitive interaction among firms is higher. H2: The degree of competitive interaction in the product market has a negative influence on the IPO’s survival time. To account for the risk a company faces in its product market regarding earnings and cash flows, I use the industry’s demand uncertainty in my study. In the literature on industrial organization, Ghosal (1991) as well as Guiso and Parigi (1999) find that demand uncertainty leads to a suboptimal level of investment in capital goods, decreasing production efficiency. For the survival time I expect the influence of - 20 - The Survivability of Initial Public Offerings demand uncertainty to be negative as operating is more risky due to the uncertainty about cash flows. H3: The demand uncertainty in the product market has a negative influence on the IPO’s survival time. The market share in the product market is an indicator for the firm’s market power. The higher the market power, the easier it is for a company to handle competition in the product market. Additionally, Chemmanur and He (2011) report a significant negative relation between the IPO company’s market share and private as well as public competitor’s market share growth after the IPO. The company’s market share at the time of the IPO is hence expected to increase the IPO’s survival time. H4: The market share has a positive influence on the IPO’s survival time. The number of competitors in an industry is not constant over time. New entrants in the market can change the competitive structure by increasing competition and decreasing profits. This poses a potential threat to incumbent companies. The threat increases with the entry rate. According to Porter’s famous five forces framework, an industry is more attractive, the higher the barriers to entry for new companies are (Porter, 1979). A low entry rate may reflect the existence of entry barriers. In a study about business failure in the Japanese manufacturing sector, Honjo (2000) finds that new businesses in an industry with a high entry rate exhibit higher mortality rates. His study differs in the basic approach: Honjo calculates the entry rate from an insample period as he tries to explain business failure with the entry rate. The purpose of my study is rather the prediction of the IPO survival time. Therefore I construct the entry rate at the time of the IPO to omit possible endogeneity issues. I expect the entry rate to negatively influence the IPO’s survival time. H5: The entry rate in the product market has a negative influence on the IPO’s survival time. The Survivability of Initial Public Offerings - 21 - To test these hypotheses, I use a set of control variables which account for the results of previous studies as mentioned in the literature review. The whole set of variables can be seen in Table 2.1. The control variables comprise firm-related variables, dealrelated variables and market-related variables. 2.4 Data The dataset contains 1,840 IPOs of firms going public on the three major stock exchanges in the US (NYSE, AMEX and NASDAQ) between 1990 and 2010 and is obtained from the Thomson SDC New Issues database. Following prior literature, ADRs, REITs, Unit IPOs, penny stock IPOs (offer price < 5 USD) as well as financial institutions are excluded from the sample. Furthermore, the IPO company has to be available in Compustat and the CRSP database with available delisting information as well as available company founding date. Finally two more modifications have to be made. IPOs with delistings due to mergers and acquisitions, exchanges or going privates are excluded from the sample as these delistings are not for negative reasons. IPOs from the NAICS sector Mining (21) and Construction (23) have to be excluded as there is no data available about industry concentration from the US Census Bureau. These restrictions yield the final sample size of 1,840 IPOs of which 703 have not survived during the observation period which ends Dec. 31 2010. Table 2.1 lists and describes the variables used in the study. Deal-related information about the IPO is obtained from the SDC database. The founding date is further merged with Jay Ritter’s data on IPO companies’ founding date, available on his website.9 The underwriter reputation ranking is the modified Carter-Manaster (1990) reputation ranking by Jay Ritter and also available on his website. Internet IPOs have been identified using Ofek and Richardson (2003), Loughran and Ritter (2004) and have also been identified by the business description from the SDC database.10 Accounting-related variables and the six-digit NAICS code are obtained from Compustat. Accounting variables are used from the fiscal year prior to the IPO. First trading day closing prices and delisting information are obtained from the CRSP 9 I want to thank Jay Ritter for making his data publicly available.

CRSP provides the delisting date as well as the reason for the delisting.11 Only delisting for negative reasons are accounted as failures and included in the sample. Table 2.2 shows a summary of the delisting reasons in the sample. Data for constructing the IPO market hotness variable is available on Jay Ritter’s website where the number of IPOs and the average initial return per month are listed.12 From the US Census Bureau I acquire data about industry size and industry concentration which are available in the Economic Census.13 The Census data is available for the years 2007, 2002 and 1997. I match each IPO with the closest available Economic Census. An alternative would have been to calculate industry concentration and market shares from all firms available in Compustat which would yield yearly observations.14 The drawback of this alternative is that Compustat only contains data about public firms. As a result, concentration ratios and market shares do not consider the effect of private firms. However, this effect is significant as Ali, Klasa and Yeung (2009) report. In their study, they find a correlation of only 13% between the concentration ratio from Compustat and from the US Census. Additionally, the benefit of having yearly observations is rather limited as industry concentration does not vary significantly from year to year. Therefore I decide to use data about industry concentration and industry size from the Economic Census. For calculating the industry demand uncertainty (idu) and the degree of competitive interaction, data from private firms is not available. These two variables are calculated using all companies available in Compustat. The demand uncertainty is constructed as the standard deviation of quarterly sales growth over a 20 quarter period using a rolling window. This allows for variation in time of the variable. I follow Chod and Lyandres (2011) and calculate seasonally adjusted sales growth. In a first step I regress the industry sales growth, calculated as the sum of sales of all companies in the same six-digit NAICS industry which have reported data available over a 20 quarter period, on four dummy variables set to one if the observation is 11 See http://www.crsp.com/documentation/product/stkind/data_coding_schemes/delisting_codes.html information about CRSP delisting codes. 12 See http://bear.warrington.ufl.edu/ritter/ipoisr.htm 13 See http://www.census.gov/econ/ 14 As can be seen in Chod and Lyandres (2011) or Chemmanur and He (2011). for further - 24 - The Survivability of Initial Public Offerings Table 2.2 Summary of Delisting Reasons Number of CRSP Delisting Code IPOs 100 Issue still trading 1137 552 Price below acceptable level 161 574 Bankruptcy 91 561 Insufficient float or assets 86 584 Not meeting exchange's financial guidelines 83 580 Delinquent in filing, non-payment of fees 74 560 Insufficient capital, surplus and/or equity 60 Other 148 as % 61.79 8.75 4.95 4.67 4.51 4.02 3.26 8.04 from the first, second, third or fourth quarter respectively and zero otherwise. The residuals from these regressions are referred to as seasonally adjusted quarterly sales growth. The industry demand uncertainty is then calculated as the standard deviation of seasonally adjusted sales growth. IPOs are matched with the demand uncertainty in their six-digit NAICS industry from the quarter in which they go public. The degree of competitive interaction (dci) is based on Sundaram et al.’s (1996) competitive strategy measure. The dci for firm i is defined as the correlation of its quarterly sales growth with the quarterly sales growth of the sum of sales of all other companies in the same six-digit NAICS industry over a 20 quarter period using a rolling window. ∆ ∆ (I) I calculate the dci for each firm available in Compustat. The sign of this variable provides insight whether the company is competing in strategic substitutes (negative sign) or in strategic complements (positive sign). This of course assumes that a company’s sales are a valid proxy for its strategic actions. In my study, I am interested in the degree of interaction and not in whether the industry competes in strategic substitutes or strategic complements, hence I use the absolute value of the correlation. To calculate the industry-dci for a given quarter, I take the average value of the absolute company-dci over all companies in the same six-digit NAICS industry which have at least ten non-missing sales growth observations.

The data is made available by the US Small Business Administration.15 The entry rate is calculated as the three year average net entry rate, defined as new number of firms over previous number of firms minus one. To allow time variation of the variable I again apply the rolling window method. Data about entry rates is only available from 1990 to 2009. IPOs after 2009 have been matched with the entry rate from 2009. Since there has been a change in the industry classification system from SIC to NAICS codes in 1997, data from 1990 until 1998 is available using the SIC 15 See http://www.sba.gov/advocacy/849/12162. - 26 - The Survivability of Initial Public Offerings Figure 2.1 Histogram of Time-to-Failure of IPO Companies 0 .05 Density .1 .15 .2 The figure shows the density histogram of failing IPOs as time from going public to delisting in years. 0 5 10 Survival Time 15 20 classification system and data from 1997 to 2009 is available using the NAICS classification system. To ensure comparability, I use the official concordance tables provided by the US Census Bureau to match the NAICS industries with the corresponding SIC industries.16 For the transition years from SIC to NAICS I use the overlapping data sets.17 Table 2.3 provides the summary statistics of the variables used in this study. As can be seen, the average survival time (survival_time) is about 8.5 years for the whole sample and 5.6 years for failed IPOs. The majority of IPOs fail within the first 5 years after going public as can be seen from Figure 2.1. This allows for the conclusion that factors at the time of the going public already provide insights about the expected survival time. 2.5 Methodology To research the factors influencing the survival time of IPOs in the aftermarket, I follow prior literature and use a duration analysis model to study the influence on the 16 See http://www.census.gov/eos/www/naics/concordances/concordances.html. For the 1999 entry rate, I calculate the growth rate from 1996 to 1997 using the matched SIC industry classification and the growth rates from 1997 to 1998 and 1998 to 1999 using the NAICS industry classification. 17 The Survivability of Initial Public Offerings - 27 - expected survival time (for example: Hensler et al.,1997 or van der Goot et al., 2009). Duration analysis deals with the time-to-failure and answers the question how long an IPO firm is expected to survive. Let T be a continuous random variable measuring the time until an IPO is getting delisted. The cumulative distribution function of T is defined as (II) The survivor function, measuring the probability of surviving past time t is given by (III) The conditional probability of leaving the initial state in the time interval t until t+h, given survival up to time t, can be expressed by (IV) The resulting hazard function is the instantaneous rate of leaving per unit of time and is defined as → | (V) To get a first insight on the survivor function of my sample, I use the Kaplan-Meier (1958) methodology (KMM) to estimate the survival function. The KMM is a nonparametric approach as it does not take explanatory variables into account and is given by (VI) where is the number of firms that have survived until time and is the number of firms that have been delisted at time . To be able to make inferences about the survival of IPO firms, I use the widely applied proportional hazard model as proposed by Cox (1972) which takes the form (VII) - 28 - The Survivability of Initial Public Offerings is the baseline hazard function and x a vector containing the explanatory variables. Cox has suggested a partial likelihood method to estimate the betas. The advantage of this model is that it does not require any assumption about the distribution of the baseline hazard function and still produces accurate and efficient estimates (Hosmer and Lemeshow, 1999). It can be shown that the log-likelihood function for the Cox proportional hazard model is given by (VIII) ∈ where is the censoring indicator, set to 1 if the observation is not censored and set to 0 if the observation is censored (Hosmer and Lemeshow, 1999). is called the risk set of firms, consisting of all firms which have not been delisted and are uncensored just before the time of delisting of observation i, . The disadvantage of the Cox model is that it only provides insights about a firm’s hazard rate but not about its expected survival time. Therefore, I additionally use a parametric log-logistic hazard model to study the expected survival time of IPOs. The difference to the Cox approach is that the distribution of the baseline hazard function is now employed in the analysis. In this specification I assume that the baseline hazard function follows a log-logistic distribution. The log-logistic hazard function is defined as (IX) where is a positive density parameter. If decreasing and when < 1, the hazard is monotonically > 1, the hazard is increasing until and then decreases to zero. The resulting log-likelihood function is given by (X) where is the censoring indicator which takes the value 1 if the data is not censored and 0 when the observation is censored. The Survivability of Initial Public Offerings - 29 - 2.6 Empirical Results This section presents the results of the analysis on IPO survival. In the first part, the dataset is analyzed using the Kaplan-Meier method to estimate the survival function. The second part presents the results of the duration analysis using the Cox proportional hazard model and a parametric log-logistic hazard model. To check the robustness of my study, I test various specifications of the hazard model. Additionally I perform a logit regression, to further test the results. 2.6.1 Kaplan-Meier Survival Functions As a preliminary analysis, I estimate the survival function using the non-parametric Kaplan-Meier estimator. Figures 2.2 and 2.3 show the estimated survival function and hazard rate of the whole sample using the Kaplan-Meier method. The hazard rate can be interpreted as the first derivative in absolute terms of the survival function. As can be seen in Figure 2.3, the hazard rate increases steadily and reaches its peak at about 4 years after the IPO and decreases afterwards. Figure 2.2 shows that the probability of surviving the first 5 years after the IPO is about 75%. Surviving 10 years after the IPO still has a probability of about 60%. The two figures again demonstrate that the company’s critical phase of surviving in the aftermarket is in the first 5 years following the IPO, allowing for the conclusion that factors at the time of the IPO have a significant influence on the survival chances. 2.6.2 Duration Analysis Table 2.4 presents the results of the duration analysis using the Cox proportional hazard model and the log-logistic survival model. As the log-logistic model is in the accelerated time-to-failure metric, the two models differ in their coefficients’ sign as the hazard rate in the Cox model is scaled by a positive factor whereas in the loglogistic model, the hazard rate is scaled by a negative factor. The coefficients in the Cox model can therefore be interpreted as the proportional effect on the hazard rate of a unit change in the independent variable and in the log-logistic model as the proportional effect on the survival time of a unit change in the independent variable. The likelihood ratio statistic is significant at the 1% level in all four regressions. For each model I perform two regressions. In the first and third regression I use the whole - 30 - The Survivability of Initial Public Offerings 0.00 0.25 0.50 0.75 1.00 Figure 2.2 Kaplan-Meier Estimate of the Survival Function 0 5 10 years 15 20 .02 .03 .04 .05 .06 .07 Figure 2.3 Kaplan-Meier Estimate of the Hazard Rate 0 5 10 years 15 20 The Survivability of Initial Public Offerings - 31 - sample. In regressions (II) and (IV) I add the variable entry_rate to the sample. As this variable is not available for my whole sample, IPOs before 1993 are excluded in this specification. Hypotheses 1-5 suggest that the firm’s product market competition, described by industry concentration, the degree of competitive interaction, industry demand uncertainty, the IPO firm’s market share and the industry’s entry rate, affect the survival time of new firms in the financial market. The results from Table 2.4 confirm the assumption that product market competition affects the survival time. For industry concentration (concentration), the results from the Cox model suggest a negative influence on the hazard rate and the log-logistic model suggests a positive influence on the survival time. This means companies operating in industries with higher concentration, have a higher expected survival time. An increase in industry concentration by one standard deviation increases the survival time by about 10%. The results confirm H1 that industry concentration has a positive influence on the IPO’s survival time. A possible explanation for this finding is that industry concentration indicates the toughness of competition in the industry. Firms going public in industries with a tougher competition, have a shorter expected survival time. The market share of the company (market_share) going public exhibits the expected effect on the hazard rate and survival time as H4 predicts, however without statistical significance. This result indicates that a company’s market power at the time of the IPO is not able to predict the chances of survival. Industry demand uncertainty (idu) exhibits counter-intuitive signs as to what H3 proposes, however the results again lack statistical significance. H3 suggests that a higher industry demand uncertainty leads to a suboptimal level of investments which in turn leads to inefficiency in the production process. This effect may already be covered by logcapex and logsales which is why the effect of idu is not statistically significant. In unreported results, I also test H3 using the intra-industry correlation of unadjusted sales growth instead of seasonally adjusted growth which does not affect the results. The degree of competitive interaction (dci) exhibits statistical significance at the 5% level in both model specifications. The effect on the survival time is negative as suggested by H2. Companies operating in industries with higher competitive interaction have a shorter - 32 - The Survivability of Initial Public Offerings Table 2.4 Regression Results of Cox proportional Hazard Model and log-logistic Survival Function The sample consists of 1,840 IPOs going public between 1990 and 2010 on NASDAQ, NYSE or AMEX.

An increase of dci by one standard deviation decreases the survival time by about 9%. This result suggests that not only industry concentration, but also the strategic interaction among the companies affects the survival time. To test H5, in regressions (II) and (IV) I add the entry rate (entry_rate) to the regression model. This reduces the number of observations to 1,747. As can be seen in regression (IV), the influence of the entry rate on an IPO’s survival time is negative and statistically significant at the 10% level. An increase in the entry rate by one standard deviation reduces the survival time by about 7%, in line with H5. In the Cox model however, the effect of the entry rate on the IPO’s hazard rate is positive but without statistical significance. This result provides weak evidence that the entry rate affects a firm’s survival chances making industries with lower entry rate more attractive, as suggested by Porter’s (1979) five forces framework. Looking at the control variables, the results are in line with prior research. A company’s age (age) is highly significant in determining the IPO’s survival time in the aftermarket, consistent with prior studies (Hensler et al., 1997, Demers and Joos, 2007). Being an internet IPO (internet) significantly reduces the survival time by 53.84% compared to non-internet IPOs. As this special type of IPO seems to exhibit a particularly high hazard rate, I will perform an analysis excluding internet IPOs in the robustness section to check whether these IPOs drive my sample. The accounting variables have the expected sign and, with the exception of ocf, are significant at least at the 10% level. The results suggest that firms with a higher capital intensity (logcapex), higher leverage (logleverage) and lower profitability (roa) have a shorter expected survival time. There is also weak evidence that less efficient firms, measured by sales over assets (logsales) have a shorter expected survival time. For the deal-related variables I find that the survival time is positively influenced by the offer price (offer_price), the underwriter reputation (underwriter), VC backing and the whether the IPO gets listed on the NYSE or AMEX (exchange) which is again consistent with prior studies (Seguin and Smoller, 1997, Demers and Joos, 2007, Jain and Kini, 2000). For the offer size (size) and the auditor reputation (auditor) I cannot find a significant effect. Controlling for the market environment, my results further show that the IPO’s first day return (initial_return), the offer-to-book ratio (otb) and - 34 - The Survivability of Initial Public Offerings when a firm goes public in a cold market (hotness) all have a positive influence on the survival time. Weak evidence is found for the IPO’s earliness to affect the survival time. For the valuation uncertainty (uncertainty), no significant effect can be found. To further test the robustness of these results, I perform various analyses which I am briefly going to present here. One common problem with duration analysis is the specification of the underlying baseline hazard function. In the study I use the loglogistic distribution. To see whether my results depend on the specified baseline distribution, I perform the analysis again using the exponential, the Weibull and the log-normal distribution. The results are presented in Table 2.5. Using different distributions has no major effect on my previous results. Furthermore, my results suggest an abnormally high hazard rate for internet IPOs. Bartov, Mohanram and Seethamraju (2002) report an anomalous behavior in the pricing and valuation of internet IPOs. To see whether these IPOs drive my results, I perform the model again excluding internet IPOs. As can be seen from regression (II) in Table 2.6, excluding the IPOs has no significant effect on my results. To test the robustness of the industry concentration measure, I use the HerfindahlHirschman Index (hhi) as an alternative measure. This index is used by the US Department of Justice and the Federal Trade Commission to evaluate the impact of horizontal mergers on the competitive environment. As the US Census Bureau only provides this index for the manufacturing sector (NAICS codes beginning with 3) the analysis is performed using only manufacturing IPOs which reduces the sample to 892. The results can be seen in regression (III) in Table 2.6. The hhi is statistically significant and increases the IPO’s survival time. An increase in the HerfindahlHirschman Index by one standard deviation increases the survival time by about 10% as does an increase in concentration. Finally, Table 2.7 provides the results of the robustness test using a logit discrete response model. A discrete response model is an alternative way to analyze the factors influencing the IPO’s delisting from the stock market.

Duration analysis is able to employ this information through censoring. In the robustness test I use a five year window given that the hazard rate is highest in the first years after the IPO (see Figure 2.1). The logit regression again confirms my previous results and provides further evidence for the influence of the entry rate. A higher entry rate increases the probability of not surviving the first five years after going public. The results from the duration analysis suggest that firms going public in industries which exhibit a higher industry concentration, a lower degree of competitive interaction and a lower industry entry rate have a higher expected survival time in the aftermarket. The results are robust to controlling for firm-, deal- and market-related factors as suggested in prior studies as well as various model specifications. My results provide certain implications for investors as well as for firms when deciding to go public. Investors should take the expected survival time of a new company into account when assessing the firm’s risk-return profile. As shown, the expected survival time does not just depend on firm, deal or market factors but also on product market competition. For private firms, my results provide valuable insights for the decision to go public. Going public is associated with high direct as well as indirect issuing costs and also with the costs of disclosing private information about the firm. Overall, my results suggest that the competitive environment affects the expected survival time for new firms in the market and is therefore associated with failure risk. Firms should include the competitive environment in their going public decision as the risk of failure may be a significant factor when comparing the costs and benefits of going public. Actually, Chemmanur et al. (2010) find that industry concentration is positively related to the decision to go public versus stay private which supports this conclusion. 2.7 Conclusion The purpose of this study is to show the relationship between the firm’s product market competition and the survival time in the aftermarket. While previous research The Survivability of Initial Public Offerings - 39 - on IPO survival has already discovered that factors related to firm, deal and market characteristics are influencing the survival time of a new company in the aftermarket, this is the first study to look at the influence of the company’s product market competition. Using a sample of 1,840 IPOs in the US between 1990 and 2010, I use a log-logistic duration analysis model along with a Cox proportional hazard model to test the influence of factors from the firm’s product market competition on the survival time in the aftermarket. I find that the IPO’s survival time increases with industry concentration and decreases with the degree of competitive interaction in the industry and also decreases with the entry rate in the industry. I cannot find evidence that the firm’s market share or industry demand uncertainty have a statistically significant influence on the IPO’s survival time. The results are robust to controlling for firm-, deal- and market-related variables, various model specifications and are further confirmed by a logit discrete response model. Overall, the results show the important role of taking the firm’s product market competition into account when predicting the IPO’s survival time in the aftermarket. For investors the results provide valuable insights when assessing the risk structure of firms going public and also for the firms themselves in their decision to go public. Variables relating to firm characteristics, deal characteristics or the financial market form just one dimension in affecting the firm’s survival. It is the interaction of these variables with conditions in the product market competition which ultimately decides over the firm’s success or failure. The firm’s product market competition should therefore be taken into account when studying IPO survival. An interesting topic for further research would be the ensuing question whether investors take the risks associated with the competitive environment into account when pricing firms or IPOs in particular. I leave that for further research. - 40 - The Survivability of Initial Public Offerings References Akhigbe, A., Borde, S. & Whyte, A. (2003).

Intra-Industry Effects of Initial Public Offerings - 45 - 3 Intra-Industry Effects of Initial Public Offerings – Insights from the Product Market Competition on the IPO’s Competitive Effect In this study I want to analyze the valuation effect of Initial Public Offerings (IPOs) on listed industry competitors and provide evidence that competitors exhibit a negative price reaction to the filing and completion of an IPO in their industry. This reaction is attributed to a competitive effect associated with an IPO. I further find that the competitive effect upon a completed IPO is negatively related to the toughness of the product market competition. IPOs in competitively weak industries, indicated by a higher industry concentration, a lower degree of strategic interaction and a lower industry demand uncertainty exhibit a stronger competitive effect on their rivals. Overall, my results provide evidence that the competitive environment is an important factor in determining the competitors’ reaction upon an IPO in the same industry. - 46 - Intra-Industry Effects of Initial Public Offerings 3.1 Introduction The Initial Public Offering (IPO) is an important step in the firm’s life cycle, allowing further growth by having access to financing from the capital market. The majority of the research on IPOs focuses on valuation effects of the issuing firm with IPO underpricing and the long-run underperformance being the most popular topics in IPO research (see e.g. Ritter, 1991; Ritter and Welch, 2002; Loughran, Ritter and Rydqvist, 1994). Yet, IPOs are not simply a firm-specific event but can have an industry wide valuation impact as the studies by Akhigbe, Borde and Whyte (2003), Hsu, Reed and Rocholl (2010) or Cotei and Farhat (2011) show. An IPO can have several, even contradicting effects on its competitors and, a priori, it is not clear which effect is dominating. This explains why different studies come to different conclusions about an IPO’s intra-industry effect.18 The purpose of this study is to further analyze the IPO’s intra-industry effect and thereby to focus on the competitive effect by looking at the firm’s product market competition using a comprehensive sample of IPOs. Previous studies show that the IPO’s external effect on listed industry competitors can be caused by information externalities or by a competitive effect. The information effect assumes that an IPO reveals private information not only about the issuing firm but about the whole industry. An IPO can have positive information externalities on competitors as the IPO is a sign for a positive or improved industry outlook. Companies do not perform an IPO when the industry outlook is not favorable as it would be more difficult to persuade investors of the equity story and the risk of paying the costs of an unsuccessful IPO would also be too high. Thus an IPO reveals private information about an improved outlook for the industry. As it is a signal for the whole industry, public competitors can also benefit from this information spillover (Akhigbe et al., 2003). Along with the information externalities, an IPO also has a competitive effect as it affects the competitive balance in the industry. Chemmanur and He (2011) argue that 18 The study of Hsu et al. (2010) finds that competitors negatively react to an IPO in the same industry. The study of Akhigbe et al. (2003) does not find a significant competitors’ response and the study by Cotei and Farhat (2011) finds a positive competitors’ reaction. Intra-Industry Effects of Initial Public Offerings - 47 - issuing firms gain an advantage over their competitors as they are provided with fresh capital, which is cheaper than debt financing and allows them to increase production as well as to employ more qualified employees or acquire related firms. Additionally, a firm enjoys greater public attention upon an IPO. In this study I will present valuable new insights for the research on the IPO’s competitive intra-industry effect by looking at the industry’s competitive environment. Previous studies have found out that industry concentration is a significant factor in explaining the intra-industry effect of IPOs (see Akhigbe et al., 2003; Cotei and Farhat, 2011; Lee, Bach and Baik, 2011). I expand the existing research by looking at further factors characterizing product market competition. Raith (2003) as well as Sharma (2011) suggest that industry concentration does not capture all dimensions of the product market competition. By using these additional variables, I am therefore able to account for an IPO’s competitive environment more accurately. The research is motivated by recent studies which have demonstrated that the firm’s product market competition is an important factor in explaining the firm’s decision to go public (Chemmanur, He and Nandy, 2010), the firm’s post-IPO operating performance (Chemmanur and He, 2011) and the rival’s post IPO market share development (Chemmanur and He, 2011 and Chod and Lyandres, 2011). Chod and Lyandres (2011) report a significant influence of the firm’s product market competition on the increase in a firm’s product market share after going public. The study by Chemmanur and He (2011) reports further evidence that going public is associated with an increase in the product market share in the years after the IPO. The authors study the decline in the product market share of both private and public competitors and find a significant influence from product market characteristics. Additionally, the authors report a significant relationship between the factors from product market competition and the operating performance in the year after the IPO. The main assumption in this study is that the IPO’s competitive effect depends on the industry’s competitive environment. In order to test this, I will analyze the influence of several factors which describe the firm’s product market competition on the rivals’ valuation response to the IPO. In a first step, I look at the valuation response of rival - 48 - Intra-Industry Effects of Initial Public Offerings firms to the filing and the completion of a firm’s IPO using the event study methodology. In a second step, I look at the factors influencing the valuation response of completed IPOs using a cross-sectional analysis. I find that the competitors’ response to an IPO filing or completion is negative, concluding that the competitive effect is dominating the information effect on average. The results further suggest that the competitors’ response is positively related to the toughness of the competitive environment. The weaker the competitive environment, the stronger is the competitive effect of an IPO in that industry. I also find that the subsample of IPOs in industries with the toughest competitive environment does not exhibit a significant response to an IPO, whereas the subsample of IPOs in industries with the weakest competitive environment exhibits a significant negative response to the IPO. The study contributes to the literature on IPO’s intraindustry effects by demonstrating the important role of the competitive environment when analyzing the IPO’s competitive effect on competitors. The remainder of this study is structured as follows: Section 3.2 provides a brief overview of the existing and related literature. Section 3.3 introduces the hypotheses about the influence of product market competition on the IPO’s external effect. Section 3.4 describes the data set and Section 3.5 presents the methodology I use for this study. In Section 3.6 the results of the event study and the cross-sectional analysis are presented and discussed. Finally, the study is concluded and summarized in Section 3.7. 3.2 Related Literature The motivation for this research reaches back to the literature on the valuation effect of firm-level announcements on competitors and deals with the question whether firm-specific events only affect the firm or have an effect on rival firms as well. Slovin, Sushka and Ferraro (1995) study the effects of equity carve-outs, IPOs, spinoffs and asset sell-offs on industry rivals. They observe a negative price reaction of rival firms in response to equity carve-outs and IPOs but find no negative effect for the other transaction types. The authors argue that these transactions convey adverse Intra-Industry Effects of Initial Public Offerings - 49 - information about the industry, as an equity sale is perceived as a sign of overvaluation, which holds true for the whole industry. In an earlier study, Slovin, Sushka and Poloncheck (1992) find that seasoned equity offerings in the banking industry trigger a negative stock price reaction in rival commercial and investment banking firms, which is attributed to adverse information of the corporate transaction. Looking at the effect of going private transactions in the US, Slovin, Sushka and Bendeck (1991) find positive abnormal intra-industry stock price reactions upon announcement. The authors offer three factors as explanation for the observed positive reaction: a buyout bid may convey private information about future industry expectations, it may increase the probability of becoming a buyout target in the industry and it may reduce the agency costs in an industry by inducing managers to improve corporate governance to prevent becoming a buyout target. Chevalier (1995) who researches the effect of leveraged buyouts on industry rivals comes to similar results. She focuses on the US supermarket industry and finds out that a leveraged buyout announcement leads to a positive stock price reaction of rivals. Chevalier hypothesizes that increasing leverage in an industry softens product market competition, which increases expected future profits. The studies of Lang and Stulz (1992) and Ferris, Jayaraman and Makhija (1997) cover bankruptcy announcements and find a negative intra-industry price reaction. The authors discover two different effects, however. A negative contagion effect, which arises due to a decreased industry outlook implied by the bankruptcy, and a positive competitive effect due to an improved competitive situation in the industry with the contagion effect dominating on average. Akhigbe and Madura (1999a) focus on the effect of an acquisition announcement in an industry and find a significant positive stock price reaction in the target’s industry. The authors explain their observation with an increased probability for rival firms to become acquisition targets as well. In a related study, Akhigbe and Madura (1999b) confirm their findings, studying acquisition announcements in the banking industry. The price reaction is positively related to factors that indicate the probability of a future acquisition of corresponding rivals. Bley and Madura (2003) study the effects - 50 - Intra-Industry Effects of Initial Public Offerings of European M&A transactions and confirm the positive intra-industry price reaction upon the announcement in their sample of European acquisitions. Studying the intra-industry effect of IPO announcements, Akhigbe et al. (2003) study a sample of IPOs in the US and confirm the hypothesis that IPOs not only convey firm-specific information but industry-wide information. However, the authors find out that on average the effect of an IPO on traded rival firms is insignificant. The authors assume that the impact of an IPO is twofold as they find evidence for a positive information effect and a negative competitive effect, which offset each other. Akhigbe et al. argue that an IPO “could signal a change in the outlook for the industry as a whole, resulting in significant valuation effects for rival firms” (2003, p.532). A negative effect is attributed to competitive effects of an IPO deriving from changes in the industry’s competitive balance due to an IPO. It is assumed that a firm is able to gain a competitive advantage by pursuing an IPO. Hsu et al. (2010) find in a sample of large firms going public that rivals exhibit a negative price reaction to the IPO announcement and the actual IPO completion and that there is a positive price reaction to withdrawn IPOs. The authors find evidence that new firms have an advantage over incumbent firms as they have lower leverage, recent financial intermediary certification and a higher degree of knowledge capital. Cotei and Farhat (2011) examine the role of venture capital in their study on the IPO’s intra-industry effect. The authors find that rivals positively respond to VC backed IPOs in their industry while there is no observable reaction to non-VC backed IPOs. The authors argue that VC backed IPOs convey superior information concerning industry outlooks compared to non-VC backed IPOs, which explains the positive valuation reaction by competitors. Lee et al. (2011) focus on the IPO’s intra-industry effect in the growing computer-related service industry. They conclude that the positive information spillover is stronger for rivals competing in the same product market than rivals competing in related product markets and that the valuation effect is positively influenced by R&D expenses and negatively by industry concentration. My research is distinctive from the above mentioned studies as I use various variables accounting for the firm’s product market competition and not only industry Intra-Industry Effects of Initial Public Offerings - 51 - concentration. Furthermore, I analyze the factors upon the completion of the IPO instead of the IPO announcement as the above mentioned studies do.19 Additionally I use a substantially larger data sample than Hsu et al. (2010) and Lee et al. (2011) and use data about industry concentration from the US Census Bureau as opposed to calculating industry concentration from firms available in Compustat, which does not account for the influence of private firms.20 A different reason for the observed intra-industry effect of IPOs is brought up by Braun and Larrain (2009). Instead of focusing on the information or competitive effect, the authors study an IPO as a possible equity supply shock in the market. In a sample of IPOs in emerging countries, the authors find significant evidence that aggregate asset prices decline after an IPO. This effect is more pronounced for larger IPOs and for assets with higher return covariance with the IPO, which can be assumed for competitors from the same industry. It is noteworthy that the results need to be interpreted with awareness of the dataset. An IPO in an emerging country with a less sophisticated capital market has a different impact than an IPO in a sophisticated capital market such as the US market. 3.3 Hypothesis Development As already stated, an IPO’s effect on rivals is not clear a priori. The competitors’ response depends on which effect of the IPO is dominating. Akhigbe et al. (2003) show that the information effect of an IPO is positive as it accounts for a positive industry outlook. This is further supported by the results from Rau and Stouraitis (2011), who show that corporate events occur in waves and follow a distinctive pattern with IPOs initiating a new wave of corporate events. This suggests that IPOs do contain information regarding the industry outlook. Thus, an IPO’s influence on competitors is positive when the information effect is dominating and negative when the competitive effect is dominating. The main assumption in this study is that product market competition influences the degree of the competitive effect. This 19 I expect the competitors’ reaction to be more meaningful upon completion of the IPO, since the success of going public is still accompanied by uncertainty at the time of filing (Busaba, 2006). Therefore, I decide to analyze the completion instead of the announcement. See the methodology section for further discussion. 20 . Ali, Klasa and Yeung (2009) find that the correlation between industry concentration calculated from Compustat and the industry concentration from the US Census Bureau is only 13%. - 52 - Intra-Industry Effects of Initial Public Offerings assumption further implies that the IPO’s information effect is independent of the competitive environment. The recent studies by Hsu et al. (2010), Chod and Lyandres (2011) and Chemmanur and He (2011) find evidence that IPOs exhibit a competitive advantage over both their listed and their private competitors. This competitive advantage changes the competitive balance in an industry and causes the adverse effect on rival companies. The degree to which IPO firms are able to gain a competitive advantage depends on the existing competitive environment in the product market. In industries, in which product market competition is already tough, the marginal benefit of going public is smaller compared to industries with a weak competitive environment. Firms can benefit more from the competitive advantage of going public, when the competitive environment is weak. Economic theory suggests that firms in a perfectly competitive environment are not able to earn economic rents. The weaker the competitive environment, i.e. the more imperfect, the more are firms able to earn economic rents. Profiting from a competitive advantage would mean earning economic rent. Therefore, the ability to benefit from a competitive advantage depends on whether the competitive environment is rather weak (imperfect) or tough (perfect) and this ultimately determines the degree of the IPO’s competitive effect on rivals. As a consequence the competitive effect is expected to be stronger for IPOs in industries with a weak competitive environment and weaker for IPOs in industries with a strong competitive environment. To test this assumption, I analyze the effect of industry concentration, the degree of strategic interaction and demand uncertainty in the industry as well as the industry’s entry rate on the rivals’ response to a competitor’s IPO. All these factors influence and shape the competitive environment in an industry. A widely accepted measure for the competitive environment in an industry, both in academic literature and in practice, is industry concentration.21 Industries with a low 21 See for example Cowling and Waterson (1976) who find that industry concentration affects firms’ price-cost ratio, Bikker and Haaf (2002) who empirically confirm the adverse effect of concentration on competition or Lang and Stulz (1992), Chevalier (1995), Sundaram, John and John (1996) or Akhigbe et al. (2003) who use industry concentration to control for competition in their studies on the intra-industry effect of firm announcements. Also see Tirole (1988) for a theoretical Intra-Industry Effects of Initial Public Offerings - 53 - concentration exhibit characteristics of perfect competition whereas industries with a high concentration exhibit characteristics of an oligopoly. The more concentrated an industry, the weaker is the competitive environment in that industry. Therefore, IPOs in industries with higher concentration are expected to have a stronger competitive effect, leading to the first hypothesis. H1: IPOs in industries with higher concentration have a stronger competitive effect. A different measure of the competition in an industry is the degree of strategic interaction (dsi) among the firms. The dsi refers to the way a firm responds to strategic choices of its competitors. According to the oligopoly literature, the interaction can either be in “strategic substitutes”, for which the dsi is negative, or in “strategic complements”, for which the dsi is positive. Competition in strategic substitutes refers to a situation in which competitors will react in the opposite way to a strategic move by a firm, which relaxes the competition and is accommodating. Competition in strategic complements refers to a situation in which competitors will react in the same way to a strategic move by a firm, which leads to an escalation and increases the competition (Bulow, Geanakoplos and Klemperer, 1985). Therefore, competition in strategic complements is more aggressive and the competitive environment is weaker in industries competing in strategic substitutes. H2: IPOs in industries competing in strategic complements have a weaker competitive effect while IPOs in industries competing in strategic substitutes have a stronger competitive effect. The uncertainty a company is facing in its demand, regarding the product market, also affects the competitive environment in the industry. Demand uncertainty increases the risks of future earnings and cash flows, which decreases the discussion. The industry concentration is also a crucial factor in decisions by the US Department of Justice or the European Commission on merger and acquisition cases. - 54 - Intra-Industry Effects of Initial Public Offerings predictability of strategic choices and makes them more difficult to make. In the literature on industrial organization, Ghosal (1991) as well as Guiso and Parigi (1999) find out that demand uncertainty in the product market is affecting the firms’ investment decisions. It is easier for firms to compete in an environment with lower demand uncertainty as the results of strategic decisions are easier to evaluate. I therefore expect that demand uncertainty makes the competitive environment tougher, leading to a weaker competitive effect of an IPO. H3: IPOs in industries with a lower industry demand uncertainty have a stronger competitive effect. New entrants in the product market can change the competitive structure in an industry by increasing competition and decreasing profits. They therefore pose a potential threat to incumbent companies. In a study about business failure in the Japanese manufacturing sector, Honjo (2000) finds that new firms in an industry with a higher entry rate also exhibit higher bankruptcy rates. One factor, which influences an industry’s entry rate, are the barriers to entry (Geroski and Schwalbach, 1991). According to Michael Porter’s famous five forces framework, an industry is more attractive, the higher the barriers to entry are for new companies (Porter, 1979). It is easier for incumbent companies to compete in an industry with a low threat of new entrants, which softens the competitive environment. H4: IPOs in industries with a lower entry rate have a stronger competitive effect. In order to test these hypotheses, I additionally use a set of control variables. To account for the firm-related factors I use the size, leverage and the profitability of the IPO firm. I expect the effect to be negative for the size of the IPO firm. Larger firms constitute a higher threat to incumbent firms. I expect that the leverage has a positive influence on the intra-industry effect as higher leveraged firms have a smaller range in competitive choices, which decreases the competitive effect of the IPO. The Intra-Industry Effects of Initial Public Offerings - 55 - profitability is expected to affect the rivals’ reactions negatively, as a more profitable firm has a larger range in competitive choices, which increases the competitive effect. To control for the market environment, I employ the overall market sentiment using the S&P 500 performance, the hotness of the IPO market and the level of the volatility index VIX. For the first two variables, I expect the effect to be positive. In hot market periods, investors are more optimistic about a firms’ growth outlook, which makes it easier for new firms to go public. This allows low quality firms to enter the market as well (Demers and Joos, 2007). In cold market periods, rather high quality firms manage to go public.22 The competitive effect is assumed to be stronger for high quality firms and therefore should be stronger in cold market periods. The VIX, also known as the “investor fear gauge”, accounts for the overall market risk. I expect the relation to be negative. The higher the systematic risk in the market, the more investors are concerned about new competitors and the stronger is the negative reaction to an IPO. Furthermore, I control for the number of listed competitors in the industry, whether the IPO got backed by a venture capital firm and whether the IPO is the first in the industry after a long silence period. The effect of the number of listed competitors is not clear a priori, yet I include this variable to test whether the rival’s reaction is depending on the number of listed companies. Cotei and Farhat (2011) assume that venture backed IPOs convey a strong positive market signal as they find evidence for a positive market reaction upon venture backed IPOs. I therefore expect the influence to be positive. The expected sign for the first IPOs in the industry after a long silence period is also expected to be positive. These IPOs should contain the strongest market signal about an improved industry outlook. Akhigbe et al. (2003) find evidence confirming this assumption. 3.4 Data and Descriptive Statistics The initial sample contains all IPO filings on NASDAQ, NYSE or AMEX between 1990 and 2010 available in the Thomson SDC New Issues Database. Financial 22 Chemmanur and He (2011) provide empirical evidence that IPOs going public in a cold market phase have higher productivity than IPOs going public in a hot market phase. - 56 - Intra-Industry Effects of Initial Public Offerings institutions, REITs, unit IPOs, spin-offs, depository receipts and penny stock IPOs (offer price below $5) are excluded from the sample leaving an initial sample of 5,651 IPO filings. By further imposing the restriction that the completed IPOs have to be available in Compustat and CRSP, the sample is reduced to 5,382. The sample is then divided in two groups: IPO filings and completed IPOs. In a next step, all events that have a confounding filing or completion in the same industry within 30 days before the event are excluded. Finally, the last restriction requires that every firm in the sample has at least five listed competitors to get an adequate picture of the competitors’ reaction. Competitors are identified using their six–digit NAICS industry code. As there is no data available about the industry entry rate for the years 1990 and 1991, which is required for the cross-sectional regression, I further have to exclude the completed IPOs in these years. This leads to a final sample consisting of 1,599 completed IPO events with 58,798 competitors from 206 different industries and 2,107 filing events with 70,619 competitors from 215 different industries. Table 3.1 provides an overview and description of the used variables in the analysis. Industry concentration data is acquired from the US Census Bureau, available in the Economic Census.23 The Census data is available for the years 2007, 2002 and 1997. I match each IPO with the closest available Economic Census. An alternative would have been to calculate industry concentration and market shares from all firms available in Compustat, which would yield yearly observations (see e.g. Chod and Lyandres, 2011 or Chemmanur and He, 2011). The drawback of this alternative is that Compustat only contains data about public firms. As a result, concentration ratios and market shares, which are constructed by using only Compustat data, do not consider the effect of private firms. However, this effect is significant as Ali, Klasa and Yeung (2009) report. In their study, they find a correlation of only 13% between the concentration ratio from Compustat and from the US Census concluding that concentration variables constructed from Compustat data are poor proxies. Additionally, the benefit of having yearly observations is rather limited as industry 23 See http://www.census.gov/econ/ Intra-Industry Effects of Initial Public Offerings - 57 - Table 3.1 Variables Definition Variable Name concentration dsi idu entry rel_size logleverage roa s&p vix hotness competitors vc first Description Average cumulative abnormal return of the portfolio of competitors in response to a filed/completed IPO Cumulative market share of the 20 largest companies in a six-digit NAICS industry Degree of strategic interaction in a six-digit NAICS industry Industry demand uncertainty in a six-digit NAICS industry Average net entry (number of firms over number of firms last year – 1) over three years in six-digit NAICS industry Relative size of the IPO firm in terms of sales compared to the median sales of listed competitors in the year of the IPO log of 1 + leverage. Leverage is defined as total liabilities over the sum of total assets and IPO proceeds Return on assets, defined as net income over total assets One-month average return of the S&P 500 index at the beginning of the event window One-month average level of the Chicago Board Options Exchange Market Volatility Index before the IPO IPO market hotness: Average IPO underpricing in the three months before the IPO Number of listed competitors in the same six-digit NAICS industry Binary variable set to one if the IPO got backed by Venture Capital and zero otherwise Binary variable set to one if the IPO is the first in its industry after a silence period of at least one year and zero otherwise concentration does not vary significantly from year to year. Therefore I decide to use data about industry concentration from the Economic Census. For calculating the industry demand uncertainty (idu) and the degree of strategic interaction (dsi), quarterly sales data are necessary, which are not available for private firms. Therefore, these two variables are calculated using all companies available in Compustat. The degree of strategic interaction (dsi) is based on Sundaram, John and John’s (1996) competitive strategy measure. The dsi for a firm is defined as the correlation of its quarterly marginal profit with the change in the combined quarterly sales of industry competitors over a 20 quarter period, using a rolling window and - 58 - Intra-Industry Effects of Initial Public Offerings allowing for time variation of the variable. The marginal profit is defined as the ratio of change in the firm’s net income to changes in its sales. ∆ ∆ (I) I calculate the dsi for each firm available on Compustat. The sign of this variable provides insight whether the company is competing in strategic substitutes (negative sign) or in strategic complements (positive sign). This, of course, assumes that the company’s sales are a valid proxy for its strategic actions. To calculate the industrydsi for a given quarter, I take the average value of the company-dsi over all companies in the same six-digit NAICS industry that have at least ten non-missing sales observations. The demand uncertainty is constructed as the standard deviation of quarterly industry sales growth over a 20 quarter period using a rolling window. Industry sales are calculated as the sum of sales of all companies in the same six-digit NAICS industry available in Compustat, which have reported data available over the 20 quarter period. IPOs are matched with demand uncertainty and the degree of strategic interaction in their six-digit NAICS industry from the quarter in which they go public. To calculate the entry rate I use the yearly number of companies in a six-digit NAICS industry. The data is made available by the US Small Business Administration.24 The entry rate is calculated as the three year average net entry rate, defined as new number of firms over previous number of firms minus one. To allow time variation of the variable I apply again the rolling window method. Data about entry rates are only available from 1990 to 2009. IPOs after 2009 have been matched with the entry rate from 2009 and the entry rates for IPOs in 1992 are calculated using the two year average net entry rate. Since there has been a change in the industry classification system from SIC to NAICS codes in 1997, data from 1990 until 1998 are available using the SIC classification system und data from 1997 to 2009 are available using the NAICS classification system. To ensure comparability, I use the official concordance tables provided by the US Census Bureau to match the NAICS 24 See http://www.sba.gov/advocacy/849/12162 Intra-Industry Effects of Initial Public Offerings - 59 - industries with the corresponding SIC industries.25 For the transition years from SIC to NAICS I use the overlapping data sets.26 Accounting-related variables are used from the fiscal year prior to the IPO and, together with the six-digit NAICS code, are obtained from Compustat. Information on the IPO proceeds and VC backing are received from Thomson Financial. Data about the S&P 500 index and the VIX are received from CRSP. Finally, data for constructing the IPO market hotness variable is available on Jay Ritter’s website where the number of IPOs and the average initial return per month are listed.27 Table 3.2 provides the summary statistics of the variables used in the cross-sectional analysis and Table 3.3 shows the distribution of all completed IPOs between 1992 and 2010 that comply with the mentioned requirements. The number of completed IPOs ranges from a minimum of 18 in 2008 to a maximum of 178 in 1996. Table 3.3 does not represent the distribution of all completed IPOs in these years. Especially the relatively low number of sample IPOs during the boom years 1997 to 2001 can be explained by the exclusion of confounding events and the requirement to have at least five listed competitors. 3.5 Methodology To analyze the effect of an IPO event, such as a filing or completion on listed competitors, I employ the standard event study methodology. This is an appropriate approach to analyze corporate events and their implications for valuation (MacKinlay, 1997). The abnormal returns are calculated for the filing and the completion date according to Thomson Financial. I follow Akhigbe et al. (2003) and form equally-weighted portfolios of listed companies that share the same six-digit NAICS code as the event firm. This approach controls for potential cross-sectional correlation of returns in the industry. Abnormal returns for a day are calculated as the 25 See http://www.census.gov/eos/www/naics/concordances/concordances.html For the 1999 entry rate, I calculate the growth rate from 1996 to 1997 using the matched SIC industry classification and the growth rates from 1997 to 1998 and 1998 to 1999 using the NAICS industry classification. 27 See http://bear.warrington.ufl.edu/ritter/ipoisr.htm. I would like to thank Jay Ritter for making this data publicly available. 26 - 60 - Variable [-5; 5] concentration dsi idu entry rel_size logleverage roa s&p vix hotness competitors vc (binary) first (binary) n=1599 Intra-Industry Effects of Initial Public Offerings Table 3.2 Descriptive Statistics of completed IPO Sample Mean Median Std Max -0.0066 -0.0066 0.0457 0.2042 59.90% 63.20% 21.18% 100.00% -0.0031 -0.0053 0.0599 0.3099 0.5157 0.1488 2.7364 73.5452 0.0375 0.0232 0.0828 0.6632 2.3673 0.6497 8.2085 142.7552 0.2697 0.2485 0.1841 1.0919 -0.3509 0.0097 5.1401 9.9784 0.0108 0.0121 0.0335 0.1518 17.6746 16.5095 5.2311 41.1832 21.53% 15.38% 20.06% 112.09% 36.7717 17.0000 42.1403 276.0000 0.4822 0.2896 - Min -0.2534 6.10% -0.3315 0.0162 -0.8221 0.0000 0.0000 -202.1000 -0.1334 10.6682 -3.38% 5.0000 - Variables are defined in Table 3.1 Variable 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 Table 3.3 Distribution of completed IPOs (1992-2010) Completed IPOs Competitors Different industries 113 3,112 69 147 3,723 80 126 3,286 75 133 3,971 74 178 4,708 94 149 4,402 89 83 2,974 52 121 4,392 57 96 3,940 55 30 1,540 24 32 1,446 25 26 1,631 20 71 3,382 46 71 4,079 40 68 3,699 41 70 3,895 34 18 713 15 20 1,349 14 47 2,511 29 Intra-Industry Effects of Initial Public Offerings - 61 - difference between the realized return of the competitor portfolio and its expected return, and are expressed by: (II) Expected returns for the competitor portfolio are estimated using a one factor market model.28 The parameters for the market model are estimated in the period [-250; -30] relative to the event date. As benchmark market index, I use the S&P 500 index. The market model can be expressed as follows: (III) The abnormal returns are calculated for each day in the event period [-30; 20] and are cumulated for each competitor portfolio: (IV) Finally, the cumulative abnormal returns are aggregated across events by computing the equally-weighted average of CARs of the competitor portfolios: (V) Average cumulative abnormal returns of competitor portfolios are reported for several event windows ranging from [-10; 10] to [-1, 1]. To test the statistical significance of the CCARs, I follow the methodolgy of Mikkelson and Partch (1988) and compute a z-statistic involving prediction errors of the market model. For analyzing the influence of the competitive environment in explaining the competitors’ reaction upon an IPO, I use the following cross-sectional model: (VI) 28 MacKinlay (1997) states that “the gains from employing multifactor models for event studies are limited” (p.18). Therefore I follow prior literature (Akhigbe et al., 2003; Lee et al., 2011; Hsu et al., 2010) and use the one factor market model. The study by Cotei and Farhat (2011) uses a constant mean return model to estimate the expected returns for their event study. - 62 - Intra-Industry Effects of Initial Public Offerings I estimate four versions of the above model. To test my results’ robustness, I control for year-fixed effects in the last two versions. The first and third version include only the variables describing the competitive environment. The second and fourth version further include the control variables to account for firm factors, the market environment and further factors. An alternative to test the effect of an IPO would be to look at the competitors’ response upon the IPO filing date. However, I expect that the competitors’ response is more meaningful upon the completion of the IPO. The management’s announcement to go public is still accompanied by great uncertainty of success and a withdrawal can occur at any point in time during the filing period (Busaba, Benveniste and Guo, 2001). In the initial sample of IPO filings, 1,234 filed IPOs at NYSE, AMEX and NASDAQ are withdrawn in the period 1990 to 2010, which is about 22%. The uncertainty about actually going public decreases steadily in time and reaches its low only at the date of issuance. I therefore decided to analyze the factors influencing the competitors’ response upon the completion instead of the IPO announcement date. 3.6 Empirical Results This section provides the empirical results to test the assumption that the competitive environment in an industry determines the degree of the IPO’s competitive intraindustry effect. In a first step, the abnormal returns of the competitor portfolio around the completion and filing of an IPO are computed. In a second step, the factors influencing the abnormal return around a completed IPO are analyzed. Finally, in a third step, I use the results from the cross-sectional analysis to create subsamples of IPOs with respect to the prevalent industry competitiveness. 3.6.1 Event Study Analysis Figure 3.1 shows the development of the cumulative abnormal returns of the competitors’ portfolio for a completed (straight line) and filed (dotted line) IPO over the event window [-30; 20]. The competitors’ reaction to a filing and completion is negative and in line with the results from Hsu et al. (2010). As the information effect Intra-Industry Effects of Initial Public Offerings - 63 - Figure 3.1 Competitors’ abnormal Return around the Completion and Filing of IPOs The figure shows the abnormal returns of the competitor portfolio upon completion and filing of an IPO for the event window. The sample consists of all completion and filing events at the NYSE, AMEX and NASDAQ between 1990 and 2010 (1992 to 2010 for completed IPOs) that have no confounding event in the same six-digit NAICS industry in the surrounding 30-day period and for which the prices of at least five listed competitors in the same industry are available. There are 2,107 filing events and 1,599 IPO events. Cumulated abnormal returns are on the y-axis and are calculated from the difference between actual return of the equally-weighted portfolio of competitors and the expected return, estimated from a one-factor market model. The parameters for the market model are estimated in the period [-250; -30] relative to the event. The x-axis comprises the timeline in days around the event (day 0). is assumed to be positive, a negative reaction indicates that the competitive effect dominates over the information effect. Investors of public rivals rather see the IPO as a threat than a sign for an improved industry outlook. The graph also shows that competitors substantially respond to a filing or a completion of an IPO already a couple of days in advance. This trend starts at 10 trading days before the event and lasts for a significant period of time after the event. Akhigbe et al.’s (2003) event window only starts at the event date which may explain why they do not find a significant competitors’ reaction in their study. A possible explanation for the strong pre-event reaction is that the uncertainty about the success of the IPO already starts to decrease in the days before the event. Hsu et al. (2010) argue that in the days before the issue date, more and more information becomes available from the road show and about potential investor demand which reduces the uncertainty about a successful completion. - 64 - Intra-Industry Effects of Initial Public Offerings The results from Figure 3.1 provide a first piece of evidence that the competitive effect dominates when a firm goes public or announces to do so. To formally test this result, I look at the abnormal returns of the competitor portfolio for different event windows and test for statistical significance. The results are presented in Table 3.4. As the graphical analysis already indicates, the competitors’ abnormal returns in response to an IPO completion or filing are negative. The results are all highly significant at the 1% level, with the exception of the [-1; 1] window for completed IPOs, which is significant at the 5% level. The negative reaction holds true for the immediate days surrounding the event and also for a number of days before and after the event. Interestingly, the competitors’ reaction is relatively similar upon an IPO filing and an IPO completion. For the longest event window [-10; 10], the abnormal return is -1.12% for a completed IPO and -1.02% for an IPO filing. For the 3-day window around the event, the abnormal return is -0.15% for completed IPOs and -0.18% for IPO filings. To increase robustness, I also perform the analysis using the Fama-French-Carhart four factor model (Fama and French, 1993; Carhart, 1997) which does not change the overall results. The results are also economically significant. The average market capitalization of incumbent firms in my sample of completed IPOs is $3.556 billion. For the longest event window, this yields an average loss of $39.823 million per competitor upon completion of an IPO in the same industry.29 On an event basis, the average total loss of all competitors amounts to $2.708 billion. Overall the results indicate that listed industry competitors exhibit a negative reaction in their share price when an IPO filing or completion occurs in their industry. To further study the IPO’s competitive effect I look at the relation between the competitors’ reaction upon the filing and the completed IPO to see whether the reaction is persistent. A reasonable assumption is to expect a positive correlation between the competitors’ reaction upon the filing and the completion of an IPO. If the competitive effect is strong upon the filing (i.e. strong negative competitors’ reaction), the competitive effect should also be strong upon the first trading day of the 29 The average market capitalization is calculated at the beginning of the event window. The average loss is calculated by multiplying the CCAR [-10; 10] with the average market capitalization. Intra-Industry Effects of Initial Public Offerings - 65 - Table 3.4 Abnormal Returns of the Competitor Portfolio on the Completion and Filing Date of IPOs The table shows the average competitor cumulative abnormal returns ( ) in response to the completion and filing of an IPO for different event windows. The sample consists of all completion and filing events at the NYSE, AMEX and NASDAQ between 1990 and 2010 (1992 to 2010 for completed IPOs) that have no confounding event in the same six-digit NAICS industry in the surrounding 30-day period and for which the prices of at least five listed competitors in the same industry are available. Abnormal returns are calculated from the difference between actual return of the equally-weighted portfolio of competitors and the expected return, estimated from a one-factor market model. The parameters for the market model are estimated in the period [-250; -30] relative to the event. To test for statistical significance, the z-statistic from Mikkelson and Partch (1988) is used. ***/**/* indicates statistical significance at the 1%/5%/10% level.

However, there is no significant correlation observable for the [-10; 10], [-5; 5], [-3; 3] and [-1; 1] window, which is surprising. This may have several reasons. For one, the market environment or firm specific factors could have changed since the filing date. Given an average time of only 93 days between filing and issue date, this does not seem to be the reason. Alternatively, the result may stem from the possibility that competitors show a reaction either at the time of the filing or at the issue time. - 66 - Intra-Industry Effects of Initial Public Offerings This may depend on the credibility of a successful IPO at the time of the filing. As already stated, there is a significant risk of withdrawal at the time of the filing. I find evidence that the response upon the issue date is significantly more negative than upon the filing date. On average, for the [-10; 10] window, the reaction upon issue is more negative by 0.58% and more negative by 0.38% for the [-5; 5] window, both statistically significant at the 5% level. 3.6.2 Analysis of the IPO’s intra-industry Effect Table 3.5 presents the results from the cross-sectional analysis of the competitors’ response upon a completed IPO in their industry for the [-5; 5] window. Models 1 and 3 only include the factors describing the industry competitiveness. Models 2 and 4 also include the control variables accounting for firm-specific factors, the market environment and further factors. In the first two columns, results are presented without year-fixed effects and, in order to test for robustness, the last two columns also show the results, which control for year-fixed effects. The primary result from the cross-sectional analysis is that the toughness of industry competition is negatively related with the competitive effect. The weaker the competitive environment, the more adverse is the competitors’ reaction. The influence of industry concentration (concentration) is negatively related to abnormal returns. This holds true for all model specifications and is statistically significant at the 5% level. The result is consistent with H1 that competitors’ in higher concentrated (less competitive) industries experience a stronger competitive effect. Akhigbe et al. (2003) also find an inverse relation between industry concentration and competitors’ abnormal returns. The study by Hsu et al. (2010) finds no relation between competitor returns and industry concentration.30 The reason for this could be that Hsu et al. only use a rather small sample of only the largest IPOs. My results indicate that an increase in industry concentration by one standard deviation decreases abnormal returns by 0.25% on average. The degree of strategic interaction (dsi) has a positive influence on the abnormal returns. Competitors in industries that are rather competing 30 Hsu et al. (2010) do not perform a cross-sectional analysis, but divide their sample in three groups according to the industry concentration and find that returns are more negative in the most concentrated group. The abnormal returns of the three groups are not significantly different though.

The results are statistically significant in all models and robust to year-fixed effects. A decrease in the dsi by one standard deviation decreases abnormal returns by 0.32%. When looking at industry demand uncertainty (idu), there is also an inverse relation with the competitive effect observable. As suggested by H3, IPOs in industries with lower demand uncertainty (weaker competitive environment) exhibit a stronger competitive effect. This effect is again significant in all model specifications. Reducing the demand uncertainty by one standard deviation leads to a decrease in the abnormal returns by 0.32%. Finally, H4 suggests that the entry rate is also inversely related to the competitive effect. In all four model specifications, the entry rate (entry) exhibits the expected sign. However, this result is only statistically significant in the random effects specification and loses significance when controlling for year-fixed effects. Therefore, H4 can only be accepted with limitations. Overall, the results provide evidence for the assumption that the toughness of the competitive environment in an industry is inversely related to the degree of the competitive effect. The results are also consistent with Lang and Stulz (1992), who find in a study on the intra-industry effect of bankruptcy announcements that the competitive effect is stronger for highly concentrated industries with low leverage, which indicates a weak competitive environment. Looking at the control variables in Models 3 and 4, the relative size of the issuing firm (rel_size) is positively related to the competitive effect, which is expected. The result is statistically significant and indicates that relatively larger IPOs pose a bigger threat to competitors. A firm’s leverage (logleverage) is inversely related to the competitive effect. However, this only holds true when not controlling for year-fixed effects. The effect of the new firm’s profitability (roa) on the competitors’ abnormal returns is negative, as expected, but lacks statistical significance at conventional levels. With the exception of the volatility index (vix), the market control variables are all highly statistically significant and exhibit the expected effect on abnormal Intra-Industry Effects of Initial Public Offerings - 69 - returns. The results for s&p and hotness suggest that the competitors’ investors draw conclusions about the new firm’s quality from the market environment around the IPO. The market volatility is only statistically significant when year-fixed effects are included and exhibits the expected sign. The number of listed competitors (competitors) does not yield statistical significance. Furthermore, I test for the influence of venture backing (vc) and whether the IPO is the first in its industry after a long silence period (first). The two variables should indicate a strong information effect as suggested by Akhigbe et al. (2003) and Cotei and Farhat (2011). As expected, the variables exhibit a positive influence on abnormal returns. However, the results fail to provide statistical significance at conventional levels. My results have implications for the firm’s decision to go public. Competitors show a more adverse reaction when a firm goes public in an industry with a weak product market competition. Firms going public in a weak competitive environment are considered to be a greater threat than IPOs in industries with a tough competitive environment. This suggests that these firms can benefit more from the competitive advantage of going public. Put differently, the marginal benefit of the competitive advantage of going public is higher in industries with a weak product market competition compared to industries with a tough product market competition. According to the theories by Bhattacharya and Ritter (1983) and Maksimovic and Pichler (2001), a firm not only faces monetary costs when going public, but also the costs of making private company information public. Only when the benefits of going public outweigh the costs, the firm decides to go public. My results suggest that the firm’s benefits of going public are higher in competitively weak industries. Therefore a weak competitive environment should induce more firms to go public. This is indeed consistent with the study by Chemmanur et al. (2010), who research the factors that influence a firm’s decision to stay private or go public. Chemmanur et al. find that industry concentration is positively related to the decision to go public. Firms in industries with a higher concentration (weaker competitive environment) are more likely to go public. - 70 - Intra-Industry Effects of Initial Public Offerings 3.6.3 Comparison of different Levels of Industry Competitiveness The results from the cross-sectional regression indicate that the competitive environment affects the degree of the IPO’s competitive effect on competitors. In this subsection I want to further analyze how the competitive effect depends on the competitive environment. I therefore construct several subsamples according to the factors describing the firm’s product market competition. The results are presented in Table 3.6. By sorting the sample according to industry concentration it is shown that the top quartile (weak competition) exhibits an average cumulative competitors’ return of -1.03% for the [-5; 5] window. The bottom quartile (tough competition) does not exhibit a significant competitors’ response. The test for difference is significant at the 5% level. By sorting according to the degree of strategic interaction or demand uncertainty the same picture is shown. The top quartile (tough competition) does not exhibit a statistically significant competitors’ reaction whereas the bottom quartile (weak competition) shows a strong negative response. Again, the test for difference is significant in both cases. These results further confirm the results from the crosssectional analysis that the competitive effect is stronger in a weaker competitive environment. Dividing the sample into IPOs in industries competing in strategic substitutes and in strategic complements does not yield a statistically significant difference. Both subsamples show a significant negative response upon an IPO. As expected, the reaction in industries competing in strategic substitutes is more negative than for strategic complements. The difference is not statistically significant though. I also sort the sample according to the industry’s entry rate, for which I find mixed results in the cross-sectional analysis. The bottom quartile subsample exhibits a significant negative price reaction while the top quartile shows no significant reaction. The difference is statistically significant at the 5% level supporting the hypothesis that the entry rate influences the competitive effect. Furthermore, I construct subsamples according to the overall competitive environment as suggested by the results from the cross-sectional analysis. I identify three factors, which describe an industry’s competitive environment and are found to Intra-Industry Effects of Initial Public Offerings - 71 - Table 3.6 Abnormal Returns of the Competitor Portfolio on the Completion Date of an IPO for different Levels of Industry Competitiveness The table shows the average competitor cumulative abnormal returns ( ) in response to the completion of an IPO. Subsamples are constructed according to the industry’s concentration, degree of strategic interaction, demand uncertainty and entry rate. The “tough” subsample is constructed as IPO events with below median industry concentration and above median degree of strategic interaction and industry demand uncertainty. The “weak” subsample is constructed as IPOs with above median industry concentration and below median degree of strategic interaction and industry demand uncertainty. ***/**/* indicates statistical significance at the 1%/5%/10% level.

Using these variables I form a subsample of IPOs in a tough competitive environment and a subsample of IPOs in a weak competitive environment. The “tough” subsample consists of all IPOs that exhibit a below median industry concentration, an above median degree of strategic interaction and an above median industry demand uncertainty (see Table 3.2). The “weak” subsample consists of all IPOs that exhibit an above median industry concentration, a below median degree of strategic interaction and a below median industry demand uncertainty. As expected, the “weak” subsample exhibits a statistically significant negative return of -1.83% for the [-5; 5] window. The “tough” subsample does not exhibit a significant abnormal return. The test for the statistical significance of the difference indicates a significance level of 1%. The results provide further evidence that the IPO’s competitive effect is stronger for competitors in industries that can be characterized by a weak competitive environment. Furthermore, the results in Table 3.6 not only indicate that the competitive effect is stronger if the competitive environment is weak but also that there is no observable competitor reaction for IPOs in industries with a tough competitive environment. The competitive effect is only observable in industries with a weak competitive environment. This can have two reasons. First, IPOs in “tough” industries do not exhibit a competitive effect. This seems rather questionable. In this case I would expect a positive competitors’ reaction due to the information effect. However the returns are negative but not statistically significant. Second, the information and the competitive effect offset each other in “tough” industries. Given my previous results, this seems more reasonable. The competitive effect is weaker in “tough” industries and cancels out with the information effect. This is how Akhigbe et al. (2003) also interpret their results as they find evidence for the existence of both the competitive and the information effect in their sample but do not find a significant competitors’ reaction overall. Intra-Industry Effects of Initial Public Offerings - 73 - 3.7 Conclusion In this study, I analyzed the reaction of listed competitors in response to a filing or completion of an IPO in the same industry and test whether the IPO’s competitive effect on industry competitors is linked to the competitive environment in the industry. I find that industry competitors yield negative abnormal returns in response to a filing or completed IPO in their industry. This result indicates that the competitive effect dominates positive information externalities associated with the event. Analyzing the competitors’ abnormal returns, I find that the industry’s product market competition is affecting the IPO’s competitive effect. Industry concentration, the degree of strategic interaction and industry demand uncertainty are all found to have a significant influence on the competitors’ abnormal returns. The weaker the competitive environment, described by higher industry concentration, lower degree of strategic interaction and lower industry demand uncertainty, the stronger is the IPO’s competitive effect. For the industry’s entry rate I only find minor evidence for influencing the competitive effect. I further find that the subsample of IPOs in industries with the toughest competitive environment does not exhibit a significant response to the IPO whereas the subsample of IPOs in industries with the weakest competitive environment exhibits a significant negative response to the IPO. A possible conclusion is that in “tough” industries the positive information effect and the competitive effect offset each other. Overall, my results present evidence that the degree of the IPO’s competitive effect depends on the surrounding competitive environment. This has implications for both private and public firms as well as for investors. When a private firm considers going public, it should also include in its decision the benefits from a competitive advantage associated with going public. Going public in industries with a weak competitive environment is accompanied with larger benefits compared to going public in industries with a tough competitive environment. Therefore, firms in competitively weak industries should, ceteris paribus, have a higher incentive to go public than firms in competitively tough industries. For investors, my results provide valuable insights on assessing the risk structure of companies, especially in young industries - 74 - Intra-Industry Effects of Initial Public Offerings with a high likelihood of new IPOs. Lastly my results are also beneficial for already listed companies as the results help to better understand the dynamics associated with an IPO in their industry. An interesting topic for further research would be to see whether the observed valuation reaction reverses over time. To answer this, a considerably longer event window would be necessary. Moreover it would be interesting to analyze if withdrawn IPOs also affect the competitors’ prices. Part 4 will cover this question.

Intra-Industry Effects of withdrawn Initial Public Offerings - 79 - 4 Intra-Industry Effects of withdrawn Initial Public Offerings In this study, I analyze the valuation response of listed competitors to a withdrawn IPO in the same industry. After controlling for confounding events, the competitor portfolio does not, on average, show a significant reaction. However, a crosssectional analysis, using variables accounting for the market environment and industry, deal and company characteristics, shows that market sentiment, industry concentration and the filing firm’s financial leverage have a significant impact on the competitors’ response. Industry concentration has a negative impact, while the impact of leverage is positive. Subsamples of withdrawn IPOs with above median industry concentration and below median leverage exhibit a statistically significant negative competitor response. The finding is consistent with the theory that the ex-ante risk of withdrawal of the IPO filing affects the competitors’ reaction. These results provide evidence for an intra-industry effect of withdrawn IPOs. - 80 - Intra-Industry Effects of withdrawn Initial Public Offerings 4.1 Introduction The filing process of an Initial Public Offering (IPO) is characterized by uncertainty of a successful outcome. Throughout the IPO process, the company has the option to withdraw its IPO at any point. Going public is an important step in a firm’s life cycle and this step is accompanied by many changes and challenges for the company. During the process of going public, the company is subject to thorough due diligence by an auditor, the underwriters, the exchange supervisory authority and, most importantly, by future investors. The result of the filing process is naturally of great interest not only to the filing company, but also to industry competitors. In the case of a successful IPO within the industry, competitors are confronted with a company that is provided with fresh capital and increased public attention. Hsu, Reed and Rocholl (2010) argue that companies that successfully accomplish an IPO exhibit a competitive advantage over their competitors. Akhigbe, Borde and Whyte (2003) argue that a successful IPO in an industry is also a sign of a favorable outlook in the product market, which can also affect competitor firms. In the case of a withdrawn IPO, the reverse occurs. Competitors no longer have to face the threat of the issuing firm’s competitive advantage, while the withdrawal can also indicate a poor or declining industry outlook. The purpose of this research is to study the competitors’ response to a withdrawn IPO within the same industry. Previous studies have only focused on the intra-industry effect of an IPO filing or the successful completion of an IPO (see Hsu et al., 2010; Akhigbe et al., 2003; Cotei and Farhat, 2011; Lee, Bach and Baik, 2011; or Slovin, Sushka and Ferraro, 1995). Studying the intra-industry effect of withdrawn IPOs is an expansion of existing literature on the intra-industry effects of IPOs in general. This study has two objectives. First, I want to detect whether competitors show a valuation reaction in response to a withdrawn IPO in the same industry. This will provide a first insight on the question of whether a withdrawn IPO is merely a firm-specific event or has industry-wide implications. Second, I want to shed light on the factors that influence the competitors’ reactions to a withdrawn IPO. Intra-Industry Effects of withdrawn Initial Public Offerings - 81 - I find that there is a significant drop in the share price of competitors after a withdrawn IPO. This result seems to be driven by confounding positive IPO events (filing or completion). After controlling for these confounding events, the competitors’ reactions to a withdrawn IPO in the same industry becomes insignificant. However, I find that industry concentration, the issuing company’s financial leverage and market variables significantly influence competitors’ responses. A withdrawn IPO in a highly concentrated industry or from a filing company with low leverage yields a significant negative response in an equally weighted competitor’s portfolio around the announcement of the withdrawal. The subsamples of withdrawn IPOs in industries with above-median concentration and below-median leverage exhibit a significant negative reaction in the competitors’ valuation. The opposite subsamples of withdrawn IPOs, with below-median industry concentration and above-median leverage, do not yield a significant reaction from competitors. The results provide evidence that the withdrawal of an IPO can trigger an information effect with an industry-wide impact; these results are consistent with the assumption that more surprise regarding the withdrawal leads to a stronger information effect. After officially filing the IPO with the SEC, the underwriter and possible investors are most interested in the company’s IPO pricing. In the US, the common price discovery process is through bookbuilding. In the pre-marketing phase, the underwriter collects valuation information from key investors and sets a price range for the offered shares (the bookbuilding range) on the basis of this preliminary information. During the subsequent bookbuilding period, investors can indicate the number of shares they want to order as well as the price. After taking orders, the underwriter builds a demand curve and sets the final IPO price. If demand exceeds supply, the underwriter allocates the shares according to the bids and the preferred investor mix. However, when a company engages an underwriter to initiate the bookbuilding process, there is no commitment by the company to actually sell the shares at the resulting IPO price. The company keeps the option to withdraw the IPO at any time. In other words, if the company feels that the resulting IPO price is too low, the IPO can be withdrawn. According to Busaba (2006), this option is an - 82 - Intra-Industry Effects of withdrawn Initial Public Offerings important factor in finding the fair company valuation. Investors will reveal a fair valuation in order to not deter the IPO candidate from proceeding. The reasons why a company perceives its market valuation as being too low, and therefore decides to withdraw its IPO, can be manifold. These reasons can theoretically be classified into two categories: firm-specific factors (e.g. unfavorable corporate news) or bad market conditions. However, it is most often a combination of reasons from both categories that leads to the company’s decision to withdraw the IPO. Both Busaba, Benveniste and Guo (2001) and Dunbar and Foerster (2008) find that approximately 20% of IPOs filed with the SEC are withdrawn during the filing period and that the most often-stated reason for the withdrawal request are unfavorable market conditions. According to the sample of this study, approximately 55% of the companies state this reason in their official withdrawal letter with the SEC. The number of studies dealing with the question of why companies withdraw their IPO is rather small. Busaba et al. (2001) find that there is no significant difference in the company size, profitability or underwriter reputation between companies withdrawing and succeeding with IPOs. However, the authors find that leverage, issue size, venture backing, general market conditions and IPO market conditions do significantly affect the probability of withdrawal. In a similar study, Dunbar and Foerster (2008) find that the issue size, venture backing, the average industry book-to-market ratio and the number of IPO filings influence the probability of withdrawal. In contrast to Busaba et al., the authors find that the underwriter does influence the withdrawal probability. The studies by Busaba et al. and Dunbar and Foerster have an important implication for the current research: investors are able to assign an ex-ante risk of withdrawal to a filing company. The higher the withdrawal probability of a filed IPO, the weaker is the surprise effect. When competitors place a high probability of withdrawal on a filed IPO, the reaction to the withdrawal announcement is rather weak, as it has been anticipated, whereas the reaction to a withdrawal announcement of a filed IPO with a rather low withdrawal probability is expected to be stronger. Therefore, the degree of surprise upon a withdrawn IPO influences competitors’ reactions. Intra-Industry Effects of withdrawn Initial Public Offerings - 83 - Theoretically, there are two ways in which an IPO can have an impact on industry competitors: as a result of information externalities or by a competitive effect. The two effects oppose each other and, a priori, it is not clear which effect will dominate. This explains why different studies come to different conclusions regarding an IPO’s intra-industry effect.31 The information effect assumes that an IPO reveals private information, not only about the issuing firm, but about the entire industry (Akhigbe et al, 2003). The IPO is a sign of a positive or improved industry outlook. Companies do not perform an IPO when the industry outlook is not favorable, as this would make it more difficult to attract investors, sell the equity story and the risk of paying the costs of an unsuccessful IPO is too high. Thus, an IPO reveals private information regarding a favorable outlook for the industry. As this is a signal for the entire industry, public competitors also benefit from this information spillover. In the case of a withdrawn IPO, the reverse is true. Withdrawing an IPO is a signal of a declining industry outlook. This release of private information affects investors’ valuations of competitor companies, leading to a downward adjustment. Therefore, the impact of the information effect of a withdrawn IPO on competitors is negative. An IPO can also have a competitive effect on competitors. Hsu et al. (2010) argue that an IPO is associated with a competitive advantage of the issuing firm. This would affect the competitive balance in the industry and investors may reevaluate the relative competitiveness of the firms in the industry. This assumption is supported by Chemmanur and He (2011) and Chod and Lyandres (2011), who find that going public is associated with a significant increase in the product market share. Chemmanur and He argue that issuing firms gain an advantage over their competitors, as they are provided with fresh capital that is cheaper than debt financing. This capital allows them to increase production, employ more qualified employees or acquire related firms. Additionally, a firm enjoys greater public attention upon the filing of an IPO. In the situation when an IPO is withdrawn, there are no changes in the competitive balance in an industry. Depending on whether the 31 Hsu et al.’s (2010) study finds that competitors react negatively to an IPO in the same industry. Akhigbe et al.’s (2003) study does not find a significant response of competitors and Cotei and Farhat’s (2011) study finds a positive reaction of competitors. However, these studies are only partially comparable, as they vary substantially in the methodologies they apply. - 84 - Intra-Industry Effects of withdrawn Initial Public Offerings market has already priced the competitive effect of a successful IPO, the competitors’ reaction to the withdrawal announcement should be positive, as the withdrawal eliminates the threat of the issuing company’s competitive advantage. As the two effects oppose each other, an insignificant competitors’ response does not necessarily mean that an IPO withdrawal is merely a firm-specific event. As Akhigbe et al. (2003) indicate it is possible that an IPO or a withdrawn IPO, will trigger both effects at the same time, which leads to the two effects cancelling each other out. For positive IPO events, that is the filing or completion of an IPO, several studies have dealt with the question of whether an IPO is a firm-specific or an industry-wide event. Akhigbe et al. (2003) study a sample of IPOs in the US and confirm the hypothesis that IPOs not only convey firm-specific information but also industrywide information. The authors find that, on average, the effect of an IPO on traded competitors is insignificant. However, in their study, they find evidence for the existence of a positive information effect and a negative competitive effect and conclude that the impact of an IPO is twofold with the effects offsetting each other. Hsu et al. (2010) use a sample of large firms going public and find that rivals exhibit a negative price reaction to the announcement of an IPO and the actual IPO date and a positive price reaction to a withdrawn IPO. The authors find evidence that new firms have an advantage over incumbent firms, as they have lower leverage, recent financial intermediary certification and a higher degree of knowledge capital. Hsu et al. also consider the intra-industry effects of an IPO withdrawal and, to the best of my knowledge, theirs is the only other study to examine this particular event. The authors report a positive abnormal return of the competitor portfolio upon a withdrawn IPO in the industry. However, there is a significant distinction between Hsu et al.’s sample and the one used in this study, which can explain the opposing observations. Hsu et al.’s sample comprises only 37 withdrawn IPO events. The authors only include events that have no other event in the surrounding six years with a larger issuing volume. Their research design is intended to study the intra-industry effect of only the largest completed or withdrawn IPOs. This sample selection clearly creates a bias towards the competitive effect, since the degree of the competitive effect is positively Intra-Industry Effects of withdrawn Initial Public Offerings - 85 - correlated to the size of the IPO (Peller, 2011), whereas the signal sent to the market by a withdrawal is not necessarily stronger for larger IPOs. Hence, it is not surprising that the competitive effect dominates in their sample of withdrawn IPOs. Cotei and Farhat (2011) examine the role of venture capital in their study on an IPO’s intra-industry effect. The authors find that rivals positively respond to venture capital (VC)-backed IPOs in their industry, while there is no observable reaction to non-VC backed IPOs. The authors argue that VC-backed IPOs convey superior information regarding the industry outlook when compared to non-VC-backed IPOs, which explains the positive valuation reaction by competitors. Lee et al. (2011) focus on an IPO’s intra-industry effect in the growing computerrelated service industry. They conclude that the positive information spillover is stronger for rivals competing in the same product market than rivals competing in related product markets. They also conclude that the valuation effect is positively influenced by R&D expenses and negatively influenced by industry concentration. From the results of these studies, it is evident that an IPO possesses an industry-wide impact. Therefore, it is just a natural step to examine the possible impact of a negative IPO event, that is, a withdrawn IPO. In this regard, the closest related topic is probably the literature on the intra-industry effect of bankruptcy announcements. In a pioneering work, Lang and Stulz (1992) find a negative intra-industry price reaction to a bankruptcy announcement in the industry. However, the authors discover two different effects: a negative contagion effect, which arises from the decreased industry outlook implied by the bankruptcy; and a positive competitive effect as a result of an improved competitive situation in the industry. They find that, on average, the contagion effect is the more dominating of the two. Ferris, Jayaraman and Makhija (1997) also find a significant negative reaction around a bankruptcy announcement, concluding that the contagion effect dominates the competitive effect. In further analyses, the authors find that, after splitting their sample into a group of competitors that are prone to the competitive effect and a group of competitors that are prone to the contagion effect, the competitive effect is - 86 - Intra-Industry Effects of withdrawn Initial Public Offerings still dominated by the contagion effect. Ferris et al. conclude that the market already anticipated the firm’s bankruptcy and thus has already priced the competitive effect in the period leading to the bankruptcy announcement. Consistent with this hypothesis, the authors find a significant positive stock price reaction by the competitor portfolio for the hundred days prior to the bankruptcy announcement. Finally, Hertzel, Li, Officer and Rodgers (2008) expand the scope and also look at the reaction along the supply chain, together with the reaction of competing firms. They too find that, on average, the contagion effect dominates the competitive effect. For the current study, the insights from literature on the intra-industry effect of bankruptcy announcements provide an important input. As the competitive effect upon a bankruptcy announcement is found to be rather weak, I expect that, for an announcement of a withdrawal, the competitive effect will be dominated by the information effect as well. Therefore, in this study, I focus on the possible information effect of a withdrawn IPO. The remainder of this study is organized in the following manner. Section 4.2 develops the hypotheses for the empirical tests. Section 4.3 describes the applied dataset. Section 4.4 introduces the methodology. Section 4.5 presents the results of the empirical analysis together with robustness tests. Finally, Section 4.6 summarizes and concludes the study. 4.2 Hypothesis Development After officially filing for an IPO, the company enters a stage of great uncertainty regarding the success of the transaction. This is also true for the competitors. As long as the new shares have not yet been sold, there is general uncertainty over whether the filing company will be able to successfully place its shares in the market. However, as shown in the studies by Busaba et al. (2001) and Dunbar and Foerster (2008), the probability of withdrawal is not the same for each company filing an IPO. There exist certain characteristics that affect the probability of withdrawal. The market can evaluate a firm’s risk of withdrawal. Busaba et al. (2001) find that underpricing is lower for firms that have a higher ex-ante probability of withdrawing Intra-Industry Effects of withdrawn Initial Public Offerings - 87 - the IPO. A possible explanation for this observation is that investors are able to evaluate the probability of withdrawal of the company and therefore reduce underpricing in order not to deter the company from proceeding. This assumption builds on Benveniste and Spindt’s (1989) information revelation theory of bookbuilding. In their model, investors are rewarded, through underpricing, for revealing private information regarding the pricing of the issue. In this context, the option to withdraw the issue is an important factor, so that investors actually reveal their private information. This has certain implications for the intra-industry effect of withdrawn IPOs. When investors assign a high withdrawal risk to a company’s IPO filing, the actual withdrawal is not considered a surprise. In contrast, when an IPO that has been assigned a rather low withdrawal risk is withdrawn, the withdrawal is more of a surprise. Furthermore, the withdrawal indicates that the initial assessment of the firm’s withdrawal risk might have been flawed. This can be caused by a misjudgment of the firm’s quality or by private information regarding the industry outlook. In the second case, informed investors signal that the expected offer price is too high, given the industry outlook, leading to the withdrawal. Therefore, the withdrawal of an IPO that has been assigned a low withdrawal risk can indicate a poor or worsening industry outlook. The surprising withdrawal reveals private information from informed investors and so provides an information effect for the entire industry. For the intra-industry effect of withdrawn IPOs, this implies that more surprising withdrawals are expected to have a stronger effect. Since the withdrawal indicates negative information, the competitors’ response is expected to be negative. In order to assess the issuing company’s ex-ante risk of withdrawal, I use variables on the basis of the insights from Busaba et al. (2001) and Dunbar and Foerster (2008). Both studies use company and deal specifications, as well as variables that account for the market environment. I extend the set of variables by also examining industry specifications. In addition to the company’s ex-ante risk of withdrawal, characteristics of competitors might also have an effect on their response. This is supported by Lang and Stulz’s (1992) and Ferris et al.’s (1997) studies, who show - 88 - Intra-Industry Effects of withdrawn Initial Public Offerings that competitor characteristics do have an effect on how they react on a bankruptcy announcement in their industry. Therefore, I also include competitor characteristics in my analysis of the intra-industry effect of a withdrawn IPO. The first industry-specific variable is industry concentration. This variable accounts for the industry’s competitive environment and is a widely used measure, both in academic literature and in practice.32 According to economic theory, industries with low concentration exhibit characteristics of perfect competition, whereas industries with high concentration exhibit characteristics of an oligopoly. In other words, the more concentrated an industry, the weaker is the competitive environment in that industry. The studies by Hsu et al. (2010), Chod and Lyandres (2011) and Chemmanur and He (2011) assume that the decision to go public is a strategic move and is associated with a competitive advantage for the issuing firm. The degree to which IPO firms are able to gain a competitive advantage depends on the existing competitive environment in the product market. In industries in which product market competition is already tough, the marginal benefit of going public is smaller when compared to industries with a weak competitive environment. Firms can benefit more from the competitive advantage of going public when the competitive environment is weak. This is consistent with the results of Chemmanur, He and Nandy (2010) who research factors that influence a firm’s decision to stay private or go public. Chemmanur et al. find that industry concentration is positively related to the decision to go public. Firms in industries with a higher concentration (weaker competitive environment) are more likely to go public. With regard to the probability of withdrawal, this means that, ceteris paribus, firms operating in more concentrated industries have a lower probability of withdrawing their IPO, as the benefits of going public are higher. Therefore, a withdrawal would come as a greater surprise. This leads to the first hypothesis: H1: Industry concentration has a negative influence on the competitors’ reaction to a withdrawn IPO. 32 See, for example, Bikker and Haaf (2002), Lang and Stulz (1992), Chevalier (1995), Sundaram, John and John (1996) or Akhigbe et al. (2003). The industry concentration is also a crucial factor in decisions by the US Department of Justice or the European Commission on merger and acquisition cases. Intra-Industry Effects of withdrawn Initial Public Offerings - 89 - The second industry-specific variable is the uncertainty a company faces regarding future sales. The uncertainty about industry demand increases the volatility of future earnings and cash flows, thereby making company valuation more difficult. Further, predicting future sales becomes more challenging. This increases the probability that the company will fail to meet expectations during the intense observation period after the IPO filing and therefore increases the risk of withdrawal. As a consequence, it is less surprising when an IPO is withdrawn in an industry with a high demand uncertainty. H2: Industry demand uncertainty has a positive influence on the competitors’ reaction to a withdrawn IPO. Industry specifications do not just affect the probability of withdrawal of the issuing firm but also the manner in which industry competitors react to the news. For example, Lang and Stulz (1992) find that the industry leverage affects competitors’ responses to a bankruptcy announcement. The higher the leverage in the industry, the stronger is the fear of contagion after a bankruptcy filing, resulting in a more negative valuation response. For withdrawn IPOs, this implies that competitors in highly leveraged industries are, ceteris paribus, more concerned with regard to the signal of a withdrawn IPO. H3: Industry leverage has a negative influence on the competitors’ reaction to a withdrawn IPO. Another factor that must be included when considering industry specifications is the size of the competitors. Ferris et al. (1997) find that the size of a competitor does affect how they react to a bankruptcy announcement. Large competitors tend to only show a reaction to a bankruptcy announcement of another large firm, but small competitors show a strong reaction to a bankruptcy announcement of large and small - 90 - Intra-Industry Effects of withdrawn Initial Public Offerings firms. Therefore, I expect that the response to a withdrawn IPO is stronger when the size of competitors is smaller. H4: Competitors’ size has a positive influence on their reaction to a withdrawn IPO. With respect to company-related variables, the first factor is the company size. Dunbar and Foerster (2008) find that the filing size has a positive effect on withdrawal risk. They conclude that large issues have more options when it comes to sources of capital, which makes them more sensitive to the expected offer price. Busaba et al. (2001) also find that the expected offer size is positively related to the risk of withdrawal. Additionally, the authors find that the size of the filing company, in terms of revenue, has a negative impact on the withdrawal risk. Companies with large revenues are easier to value, which reduces the withdrawal risk. With regard to the response to a withdrawn IPO, I expect that the impact of the offer size is positive on the competitors’ reaction while the impact of the company size is negative. H5: The expected offer size has a positive influence on the competitors’ reaction to a withdrawn IPO. H6: The filing company’s size has a negative influence on the competitors’ reaction to a withdrawn IPO. Another crucial company characteristic, apart from its size, is the financial leverage of the company. The firm’s leverage is a basic measure of its bankruptcy risk. Here, higher leverage is associated with a higher bankruptcy risk (see Altman, 1986; Shumway, 2001; Hillegeist, Keating, Cram and Lundstedt, 2004). Higher leverage is also strongly associated with the survival chances of an IPO company. Demers and Joos (2007) and Peller (2012) find a strong negative relationship between leverage and the chance of survival in the aftermarket for IPO companies. Busaba et al. (2001) also use financial leverage to explain withdrawal risk. However, the authors do not Intra-Industry Effects of withdrawn Initial Public Offerings - 91 - interpret leverage as a company risk factor but that a higher debt ratio indicates better access to alternative sources of financing. Therefore, the authors expect that leverage increases the risk of withdrawal, as these companies are more sensitive to the IPO price because they have better access to alternative financing. Busaba et al. find that leverage has a significant positive influence on withdrawal risk. In this study, I interpret the company’s financial leverage as a risk factor. Studies on bankruptcy and survival prediction show that firms with low leverage are more stable. Therefore, these companies should be less sensitive to the industry outlook and current market conditions. However, both interpretations suggest a positive relation between financial leverage and the risk of withdrawal. As a consequence, the signal associated with the withdrawal of a company with low leverage should be stronger. H7: The filing company’s financial leverage has a positive influence on the competitors’ reaction to a withdrawn IPO. The time span between filing and completing the IPO depends on a variety of factors and is not foreseeable at the time of the filing. According to the Thomson Financial New Issues Database, between 1990 and 2010, the average time between filing and issue date was 100 days. It can be assumed that investors associate a higher withdrawal risk with filing companies that have passed a certain amount of time. Therefore, IPO filings that are withdrawn after a certain time span come as less of a surprise. A possible benchmark is the average time between filing and completion, plus one standard deviation. For competitors, a withdrawn IPO after this period would have a positive influence. H8: The amount of time between filing and withdrawal has a positive influence on the competitors’ reaction to a withdrawn IPO. A further deal-related factor is the issuing firm’s underwriter. It is assumed that underwriters with high reputation are able to select high-quality issues. Jain and Kini - 92 - Intra-Industry Effects of withdrawn Initial Public Offerings (1999) find evidence for the successful selection process of prestigious underwriters; they find that underwriter reputation is positively related to the post-issue performance of IPO companies. In addition, Demers and Joos (2007) find that the likelihood of survival of a new company in the market is also positively influenced by underwriter reputation. This would suggest that underwriter reputation decreases the withdrawal risk. However, findings on the influence of the underwriter on withdrawal risk are inconclusive. While Busaba et al. (2001) do not find a significant relation, Dunbar and Foerster (2008) find that the underwriter does have a significant impact on the withdrawal risk. I will test if there is a relation between the issuing firm’s underwriter and the competitors’ response and assume that more prestigious underwriters are associated with a stronger reaction. H9: The prestige of the issuing firm’s underwriter has a negative influence on the competitors’ reaction to a withdrawn IPO. According to Jain and Kini (2000), another sign of a quality company is the engagement of a private equity or venture capital company. In their study, they find that venture-backed IPO companies have better chances of survival in the aftermarket. Brav and Gompers (1997) find that venture-backed issues also outperform non-venture-backed IPOs in the long-run.33 The presence of venture capital also has an impact on the company’s withdrawal risk. Both Busaba et al. (2001) and Dunbar and Foerster (2008) find that the presence of venture capital decreases the company’s risk of withdrawal. With respect to the intra-industry effect, I expect that both the level of surprise and, therefore, the effect are stronger when the issuing firm has been backed by venture capital or by a private equity investor. H10: The presence of a private equity or venture capital investor has a negative influence on the competitors’ reaction to a withdrawn IPO. 33 However, the outperformance found in Brav and Gompers (1997) is only significant when returns are equally weighted. For value weighted returns, the outperformance is not significant. Intra-Industry Effects of withdrawn Initial Public Offerings - 93 - The third group of variables controls for the market environment. This is a very important group, as the market situation provides the overall sentiment with which the signal is interpreted by the market. The first market variable is the overall market situation, represented by the performance of the S&P 500 index. The performance after the official filing has a strong influence on whether the company can achieve an acceptable IPO price during the bookbuilding phase. Dunbar and Foerster (2008) find that the post-filing return of the NASDAQ Composite Index has a significant negative impact on withdrawal risk. Busaba et al. (2001) show similar findings. When the market sentiment is negative, it is not surprising that an IPO is withdrawn, that is, the information spillover is very low. However, when the overall market environment is positive, a withdrawn IPO sends a strong signal that indicates private information regarding the industry outlook. Thus, the intra-industry effect should be stronger when the post-filing performance has been more positive. H11: The post-filing market performance has a negative influence on the competitors’ reaction to a withdrawn IPO. A further variable used to measure the overall market sentiment is market volatility. Market volatility is represented by the VIX, which accounts for the systematic risk in the market. Whaley (2000) finds that the VIX is a good measure of investors’ overall level of fear. However, the study discovers an asymmetric behavior of the volatility index. The stock market reacts more negatively to an increase in the VIX than it reacts positively to a decrease in the VIX. Therefore, the VIX is more a measure of investors’ fear than it is of their excitement. Market volatility also plays an important role in the price finding of a new issue. Volatile markets make it more difficult for the underwriter to set an acceptable IPO price. Therefore, it is less surprising when a company withdraws its IPO in times of high volatility. In addition, high volatility already indicates a negative outlook, which reduces the marginal information gain - 94 - Intra-Industry Effects of withdrawn Initial Public Offerings from a withdrawn IPO. Therefore, I expect that the information signal of a withdrawn IPO is stronger in times of low volatility. H12: The market volatility before the withdrawal has a positive influence on the competitors’ reaction to a withdrawn IPO. Along with variables for the overall market, the new issues market can also provide valuable insight into how competitors react to a withdrawn IPO. As is true for most corporate events, IPOs occur in waves (Rau and Stouraitis, 2011). Ritter (1991) argues that, when going public, companies are able to take advantage of opportunity windows of great optimism among investors, which is a possible explanation for the wave phenomenon (Lowry, 2003). The impact of hot IPO markets on the intraindustry effect of a withdrawn IPO is attenuating. When an IPO is withdrawn while other companies are able to successfully place their new shares in the market, the withdrawal is unlikely to provide information regarding the industry outlook. Instead, the withdrawal is rather considered to be due to firm-specific factors. Therefore, the information signal of a withdrawn IPO is expected to be stronger in cold IPO markets. H13: IPO market hotness has a positive influence on the competitors’ reaction to a withdrawn IPO. Finally, the number of previously withdrawn IPOs is also expected to influence the intra-industry effect. In a period of numerous withdrawn IPOs, the information gain of a further withdrawn IPO is rather limited. It is also less surprising that an IPO is withdrawn when the market has recently witnessed many withdrawals. Hence, it is reasonable to expect that the information signal is weaker in times of numerous IPO withdrawals. H14: The number of previously withdrawn IPOs has a positive influence on the competitors’ reaction to a withdrawn IPO. Intra-Industry Effects of withdrawn Initial Public Offerings - 95 - 4.3 Data and Descriptive Statistics The dataset comprises all withdrawn IPOs between 1996 and 2011 that have been filed for the NYSE, AMEX or NASDAQ and has been obtained from the Thomson Financial New Issues database. This yields an initial sample of 1,164 withdrawn IPOs. The year 1996 is chosen because it is the first year of good coverage of filing documentation in the SEC’s EDGAR database. The initial sample excludes Depository Shares/Receipts, Unit Offerings, Spin-Offs, Financial Institutions, REITs and closed-end funds. It also excludes filings from mining (NAICS 21) and construction (NAICS 23) companies, as there is no data on industry concentration available for these industries from the US Census Bureau. Further restrictions are imposed on the sample. All events that have a confounding withdrawal event either 30 days before or 20 days after the event are exluded in order to increase the robustness of the results.34 Furthermore, the initial IPO filing and the registration withdrawal letter for the event have to be available in the SEC EDGAR database. Finally, every withdrawing company in the sample is required to have at least five listed competitors to get an adequate picture of the competitors’ reactions. Competitors are identified using their six-digit NAICS industry code. This yields a final sample of 428 withdrawn IPO filings from 107 different industries, with an accumulated total of 21,045 competitors. Table 4.1 provides an overview of the variables used to explain the intra-industry effect of a withdrawn IPO. Accounting data on industry competitors are acquired from Compustat. Stock prices of the competitors and market data are retrieved from the Center for Research in Security Prices (CRSP). Information regarding the filing company is acquired from the Thomson Financial New Issue Database and cross-checked against the filing in the SEC EDGAR database. The underwriter reputation ranking is the modified Carter-Manaster (1990) reputation ranking by Jay Ritter and is available on his website.35 The binary variable for a private equity (PE) or venture capital (VC) investor is set to one when, according to the S-1 filing, at least one PE or VC investor with a stake of 5% or more exists before the offering. The binary variable time is set 34 35 A confounding event is defined as a withdrawn IPO in the same six-digit NAICS industry. I wish to thank Jay Ritter for making his data publicly available.

I match each IPO with the closest available Economic Census. An alternative would have been to calculate the industry concentration for all firms available in Compustat, which would yield yearly observations. The drawback of this alternative is that Compustat only contains data on public firms. As a result, concentration ratios constructed using only Compustat data do not consider the effect of private firms. This effect is significant, as reported by Ali, Klasa and Yeung (2009). In their study, they find a correlation of only 13% between the concentration ratio from Compustat and from the US Census, concluding that concentration variables constructed from Compustat data are poor proxies. In addition, the benefit of having yearly observations is rather limited, as industry concentration does not vary significantly from year to year. Therefore, I decided to use data from the Economic Census in order to represent industry concentration more accurately. Demand uncertainty is constructed as the standard deviation of quarterly industry sales growth over a 20-quarter period using a rolling window. Here, I follow Chod and Lyandres (2011) and calculate seasonally adjusted sales growth. As a first step, I regress the industry sales growth on four dummy variables, set to one if the observation is from the first, second, third, or fourth quarter respectively, and zero otherwise. The industry sales growth is calculated as the sum of the sales of all companies in the same six-digit NAICS industry, available from Compustat, that have reported data available over the 20-quarter period. The residuals from these regressions are referred to as seasonally adjusted quarterly sales growth. The industry demand uncertainty is then calculated as the standard deviation of seasonally adjusted sales growth. IPO filings are matched with demand uncertainty in their six-digit NAICS industry from the quarter in which they request the withdrawal. 36 According to the Thomson Financial New Issues Database, the average time between filing and issue date is 100 days with a standard deviation of 100 days. 37 See http://www.census.gov/econ/ - 98 - Intra-Industry Effects of withdrawn Initial Public Offerings Table 4.2 Descriptive Statistics of the Sample of withdrawn IPOs Variable Mean Median Std.

Table 4.2 presents the summary statistics for the sample variables. One comparable variable between the sample of withdrawing companies and industry competitors is the financial leverage. The descriptive statistics reveal that the withdrawing companies have a higher leverage than their industry competitors. The difference is statistically significant at the 5% level (t-statistic: 2.32). Busaba et al. (2001) show similar results. In their study, they compare the debt ratio of successful IPO companies and withdrawing companies and find that withdrawing companies exhibit 38 See http://bear.warrington.ufl.edu/ritter/ipoisr.htm Intra-Industry Effects of withdrawn Initial Public Offerings - 99 - a significantly higher debt ratio. Not reported in Table 4.2 is the average number of competitors, which is 49.2 with a median of 18.5. The minimum number of competitors, as required by the sample selection, is 5 and the maximum number is 255. 4.4 Methodology In order to analyze whether a withdrawn IPO is just a firm-specific event or whether it has an intra-industry effect, I use the standard event study methodology. This is an appropriate approach for analyzing corporate events and their implications for valuation (MacKinlay, 1997). Abnormal returns are analyzed for the surrounding time of the official date of withdrawal according to the SEC filing. Here, I follow Akhigbe et al. (2003) and Hsu et al. (2010) and form equally-weighted portfolios of listed companies that share the same six-digit NAICS code as the event firm. This approach controls for potential cross-sectional correlation of returns in the industry.39 Abnormal returns for a day are calculated as the difference between the realized return of the competitor portfolio and its expected return and are expressed in the following manner: (I) Expected returns for the competitor portfolio are estimated using a one-factor market model.40 The parameters for the market model are estimated in the period [–250; –30] relative to the event date. As a benchmark market index, I use the S&P 500 index. The market model can be expressed in the following manner: (II) 39 In order to check for the robustness of my result, I also test a value-weighted competitor portfolio. MacKinlay (1997) states that “the gains from employing multifactor models for event studies are limited” (p.18). Therefore, I follow prior literature (Akhigbe et al., 2003; Lee et al., 2011; Hsu et al., 2010) and use the one-factor market model. The study by Cotei and Farhat (2011) uses a constant mean return model to estimate the expected returns for their event study. In order to check the robustness of my result, I also perform the event study using the Fama-French-Carhart four-factor model (Fama and French, 1993; Carhart, 1997). 40 - 100 - Intra-Industry Effects of withdrawn Initial Public Offerings The abnormal returns are calculated for each day in the event period [–30; 20] and are cumulated for each competitor portfolio: (III) Finally, the cumulative abnormal returns are aggregated across events by computing the equally-weighted average of CARs of the competitor portfolios: (IV) The average cumulative abnormal returns of competitor portfolios are reported for several event windows. In order to test the statistical significance of the CCARs, I follow the methodolgy of Mikkelson and Partch (1988) and compute a z-statistic involving prediction errors of the market model. 4.5 Empirical Results The purpose of this section is to provide empirical results to answer the question of whether a withdrawn IPO is merely a firm-specific event or has industry-wide implications. Therefore, as a first step, results regarding competitors’ valuation responses to a withdrawn IPO in the same industry are presented in order to ascertain whether there is a significant overall reaction to a withdrawal. As a second step, the competitors’ reactions are analyzed using a cross-sectional model in order to ascertain the influence of variables that account for the ex-ante risk of withdrawal. To explain competitors’ reactions, I use industry, firm, deal and market variables. In the third step, using the results from the cross-sectional model, I form subsamples and test the competitors’ reactions. 4.5.1 Intra-industry Effect of a withdrawn IPO Figure 4.1 depicts the development of the cumulative abnormal returns of the competitor portfolio around a withdrawn IPO. As can be seen, the competitors’ reaction is negative, which indicates that competitors are concerned about the implied information effect of a withdrawn IPO in the industry. Interestingly, the reaction already begins a couple of days before the actual event date. Hsu et al. (2010) also find that competitors’ reaction to a completed or a withdrawn IPO begins a couple of Intra-Industry Effects of withdrawn Initial Public Offerings - 101 - Figure 4.1 Competitors’ abnormal Return around withdrawn IPOs This figure shows the abnormal returns of the competitor portfolio upon a withdrawn IPO within the event window. The sample comprises all withdrawn IPOs at the NYSE, AMEX and NASDAQ between 1996 and 2011. These IPOs have no confounding withdrawal events in the same six-digit NAICS industry in the surrounding 30-day period and the prices of at least 5 listed competitors in the same industry are available. There are 428 withdrawn IPO events. The cumulated abnormal returns are shown on the y-axis and are calculated as the difference between the actual return of the equally-weighted portfolio of competitors and the expected return, estimated from a one-factor market model. The parameters for the market model are estimated in the period [–250; –30], relative to the event. The x-axis represents the timeline, in days, around the event (day 0). days before the official announcement date. The reason might be that IPO withdrawals are often preceded by bad news, either firm-specific or market-related. Furthermore, Figure 4.1 shows that, at approximately 14 days after the event date, the cumulative abnormal returns begin to rise again, which is a sign of a price reversal. This could indicate that the withdrawal is more of a sentiment shock than a release of private information. The results from Figure 4.1 provide the first evidence that competitors suffer a drop in their share price after a withdrawn IPO in the industry. In order to formally test these results, panel A in Table 4.3 provides the abnormal returns of the competitor portfolio for different event windows and tests for statistical significance. With the exception of the [–5; 5] window, all event windows exhibit significantly negative abnormal returns, which supports the graphical analysis. For the [–20; 10] window, the drop in share price is –0.64% and is highly significant. For the event windows - 102 - Intra-Industry Effects of withdrawn Initial Public Offerings Table 4.3 Abnormal Returns of the Competitor Portfolio on the Withdrawal Date of IPOs This table presents the average competitor cumulative abnormal returns ( ) in response to the withdrawal of an IPO for different event windows. The sample comprises all withdrawal events at the NYSE, AMEX and NASDAQ between 1996 and 2011. The IPOs have no confounding withdrawal event in the same six-digit NAICS industry in the surrounding 30-day period and the prices of at least 5 listed competitors in the same industry are available. Abnormal returns are calculated as the difference between the actual return of the equallyweighted portfolio of competitors and the expected return, estimated from a one-factor market model. The parameters for the market model are estimated in the period [–250; –30], relative to the event. In order to test for statistical significance, the z-statistic from Mikkelson and Partch (1988) is used. Panel A contains the results for the full sample of 428 withdrawn IPOs. Panel B includes only those withdrawn IPO events that have a confounding positive IPO event (i.e. filing or completion) in the industry 20 days before or after the withdrawal event. Panel C contains only those withdrawn IPO events that have no confounding positive IPO event in the industry 20 days before or after the withdrawal event. ***, **, and * indicate statistical significance at the 1%, 5%, and 10% levels.

In unreported results, the competitors’ reaction is also tested using the Fama-FrenchCarhart four-factor model (Fama and French, 1993; Carhart, 1997) to estimate the expected returns and also using a value-weighted competitor portfolio. Both Intra-Industry Effects of withdrawn Initial Public Offerings - 103 - specifications provide the same result of a significantly negative competitors’ response to a withdrawn IPO in the industry. The sample selection controls for IPO withdrawals that are confounding events. However, other withdrawals are not the only events that can interfere with competitors’ reactions. The opposite event, that is, an IPO filing or a successful launch of an IPO, can also interfere. Previous studies (e.g. Hsu et al., 2010; Peller, 2011) find a strong, negative response from a competitor portfolio upon the filing or completion of an IPO. It is possible that these events also interfere with competitors’ responses to a withdrawn IPO. Therefore, I examine each withdrawal event and check whether it has a confounding positive IPO event (filing or completion) in the same industry 20 days before or after the withdrawal event. This creates a subsample of withdrawn IPO events without confounding positive IPO events (a clean subsample with 291 withdrawn IPOs), and a subsample of withdrawn IPO events that include confounding positive IPO events (a contaminated subsample with 137 withdrawn IPOs). Figure 4.2 depicts the development of the cumulative abnormal returns for the two subsamples graphically. The dotted line shows competitors’ reactions in the clean sample, while the straight line indicates competitors’ responses in the contaminated subsample. The graphic clearly shows that there is a strong, negative response in the contaminated subsample, while there is barely any observable reaction in the clean subsample. This indicates that the observed negative competitor reaction in the full sample is driven by contaminated positive IPO events. Examining the cumulative abnormal returns for different event windows provides the same conclusion. As panel B in Table 4.3 shows, competitors’ reactions are significantly negative when there is a confounding positive IPO event, while the competitors’ reaction is not statistically significantly different from zero in the clean subsample (see panel C in Table 4.3). Hsu et al. (2010) also examine intra-industry effects of IPO withdrawals. The authors report a positive abnormal return of 1.35% in the [–10; 10] window. However, as already stated, the different results can be due to the study design. Their sample comprises only 37 withdrawal events, as their research design is intended to study the intra-industry effect of only the largest completed or withdrawn IPOs. - 104 - Intra-Industry Effects of withdrawn Initial Public Offerings Figure 4.2 Competitors’ abnormal Return around withdrawn IPOs (controlling for confounding positive IPO Events) This figure depicts the abnormal returns of the competitor portfolio upon a withdrawn IPO for the event window. The sample is divided into a subsample of withdrawn IPOs that have a confounding positive IPO event (filing or completion) in the same industry 20 days before or after the withdrawal event (contaminated subsample) and a subsample of withdrawn IPOs that have no confounding positive IPO event in the same industry 20 days before or after the withdrawal event (clean subsample). There are 137 contaminated withdrawn IPO events and 291 clean withdrawn IPO events. Cumulated abnormal returns are shown on the y-axis and are calculated as the difference between the actual return of the equally-weighted portfolio of competitors and the expected return, estimated from a one-factor market model. The parameters for the market model are estimated in the period [–250; –30], relative to the event. The x-axis comprises the timeline in days around the event (day 0). My results imply that withdrawn IPOs, on average, have no observable effect on competitors. As already outlined, this does not have to mean that a withdrawn IPO is merely a firm-specific event. It is possible that two opposing effects occur upon a withdrawal and that these effects offset each other (Akhigbe et al., 2003). A further possible explanation is that not all withdrawn IPOs trigger an information effect. As already outlined, I assume that a withdrawn IPO’s information effect depends on its degree of surprise. Non-surprising withdrawals provide no new information. Therefore, it is possible that the sample, which comprises both surprising and nonsurprising withdrawals, yields no significant reaction on average. In order to finally answer whether a withdrawn IPO has an industry-wide impact, I perform a crosssectional analysis in the following section. Intra-Industry Effects of withdrawn Initial Public Offerings - 105 - 4.5.2 Cross-sectional Results In order to analyze competitors’ responses to a withdrawn IPO in their industry, I use variables that account for the industry, firm and deal characteristics, as well as for the market environment. Since I am interested in the intra-industry effect of a withdrawal, I use the clean subsample of withdrawn IPOs, that is, the subsample adjusted to only include IPO withdrawals with no confounding positive IPO event. As a dependent variable, I choose the cumulative abnormal return over the [–10; 5] window. As already mentioned, both my results and previous studies have shown that a large portion of competitors’ responses occurs before the actual event date. To cover this reaction, I choose a rather long event window. However, the results are also robust to shorter event windows. Table 4.4 presents the results from the cross-sectional analysis using the clean subsample. Panel A shows the influence of industry-related variables. With the exception of industry concentration (concentration), all variables lack statistical significance. Industry concentration is significant and shows a negative influence on competitors’ reactions, as suggested by H1. Higher industry concentration means stronger adverse intra-industry effects of a withdrawn IPO. The result is also robust when the entire model is applied, as can be seen in panel D of Table 4.4. These results suggest that industry demand uncertainty (idu), competitors’ leverage (lev_ind) and size (size_ind) have no influence on competitors’ reactions. Therefore, hypotheses 2 to 4 are not accepted. Panel B in Table 4.4 shows the impact of the firm and deal characteristics. As with the industry variables, the explanatory power is rather low. Only the firm’s leverage (lev) exhibits a statistically significant correlation with competitors’ responses. As proposed by H7, the impact is positive. Here, higher financial leverage of the filing company (lev) implies more positive competitors’ reactions to a withdrawal. This is consistent with the assumption that more surprising withdrawals mean more adverse intra-industry effects. In other words, when a firm with high leverage withdraws its IPO, competitors rather interpret the withdrawal to be due to firm-specific factors than to private information regarding the industry outlook. The variable lev is also - 106 - Intra-Industry Effects of withdrawn Initial Public Offerings Table 4.4 Cross-sectional Variation in Competitors’ Valuation Effects upon a withdrawn IPO This table shows the results of estimating a cross-sectional regression on the competitors’ cumulative abnormal return ( ) upon a withdrawn IPO in their industry for the event window [–10; 5]. The sample comprises all withdrawn IPOs at the NYSE, AMEX and NASDAQ between 1996 and 2011. The IPOs have no confounding withdrawal event in the same six-digit NAICS industry in the surrounding 30-day period and the prices of at least 5 listed competitors in the same industry are available. The sample has further been adjusted to include only withdrawn IPOs that have no confounding positive IPO event (filing or completion) in the surrounding 20-day window. Abnormal returns are calculated as the difference between the actual return of the equally-weighted portfolio of competitors and the expected return, estimated from a one-factor market model. The parameters for the market model are estimated in the period [-250; -30], relative to the event. The variable constant is the cumulated market share of the 20 largest companies in a six-digit NAICS industry, idu is the industry demand uncertainty calculated as the std of sales growth, lev_ind is the median leverage of the competitor portfolio, size_ind is the median sales of the competitor portfolio, offer_size is the expected proceeds from the IPO, size is the company’s sales, lev is the company’s leverage, time is a binary variable set to one if the time between filing and withdrawal is longer than 200 days and zero otherwise, uw_rank is the Carter-Manaster (1990) underwriter reputation ranking, pe/vc is a binary variable set to one if the IPO received backing from a VC or PE investor and zero otherwise, s&p is the return of the S&P 500 index between the filing date and the withdrawal date (beginning of the event window), vix is the one-month average level of the CBOE Market Volatility Index before the withdrawal, hotness is the average IPO underpricing in the three months before the withdrawal and num_withdrawn is the number of withdrawn IPOs in the two months before the withdrawal. ***, **, and * indicate statistical significance at the 1%, 5%, and 10% level.

The offer size (offer_size), the filing company’s size (sales), the time of the withdrawal (time), underwriter reputation (uw_rank), and private equity or venture backing (pe/vc) have no significant impact. Therefore, hypotheses 5 and 6, and 8 to 10 are not accepted. The influence of the market environment is presented in panel C of Table 4.4. As expected, the market environment has a strong impact on competitors’ reactions. With the exception of the overall market (s&p) all variables are statistically significant. However, the number of withdrawn IPOs (num_withdrawn) becomes insignificant when all variables are applied (see panel D). The market volatility (vix) has a positive impact and is highly significant. As suggested by H12, this result indicates that, during times of high uncertainty, the marginal gain of information from a withdrawn IPO is rather small. H13 suggests that during a hot IPO market phase, a withdrawn IPO is less considered a bad market signal, which is supported by the results in Table 4.4. The impact of hotness is positive and statistically significant. The results are unchanged when the full set of variables is applied in panel D. The influence of the number of withdrawn IPOs (num_withdrawn) is negative, which contradicts H14. It seems as if the information effect (and with that also the adverse effect) from a withdrawn IPO increases with the number of previous IPO withdrawals. A possible explanation is that the information signal becomes more credible when more IPOs have already been withdrawn. However, the effect of num_withdrawn becomes insignificant when applying the whole set of variables (see Panel D). The return of the overall market between filing and withdrawal (s&p) has the expected negative impact but lacks statistical significance. It seems as if the other market sentiment variables already cover all the information from the overall market performance. The results from the cross-sectional analysis show that a large part of competitors’ reactions is due to the market environment. However, the cross-sectional analysis does show that industry concentration and the filing firm’s financial leverage have a significant impact even when controlling for the market environment. The results are also unchanged when controlling for year-fixed effect. Thus, the industry - 108 - Intra-Industry Effects of withdrawn Initial Public Offerings environment and firm characteristics have a significant impact on how competitors’ investors interpret a withdrawn IPO in the industry. This is evidence that a withdrawn IPO is not just a firm-specific event, but also has an intra-industry effect. 4.5.3 Results from the subsample Analysis In order to gain further insight into how competitors respond to a withdrawn IPO in the industry, I examine two particular factors, namely industry concentration and the filing firm’s leverage. These two factors exhibit a statistically significant impact on competitors’ responses. Therefore, I construct several subsamples, sorted by industry concentration and financial leverage. The sample is divided into an above-median and below-median subsample and tested for a statistically significant difference. Table 4.5 presents the results of the subsample analysis. Examining the results of the sample sorted by industry concentration shows that, for withdrawn IPOs in industries with a high concentration, competitors exhibit a significantly negative response for different event windows. For the [–15; 1] window, the abnormal return is even –1.21%. The group of withdrawn IPOs in industries with a low concentration exhibits positive abnormal returns, although without statistical significance. The test for difference is statistically significant, at least at the 10% level, with the exception of the [–1; 3] window. These results provide further confirmation for H1. As going public in high-concentration industries is associated with more benefits, a withdrawal is considered to be less likely. The opposite case, that is, a withdrawal in a low-concentration industry, does not exhibit a significant impact on competitors. The filing company’s leverage also has a significant impact on how competitors react to a withdrawn IPO. As is evident from Table 4.5, the withdrawal of a highly leveraged company does not trigger a significant competitor reaction. In contrast, the withdrawal of a company with low leverage has a significantly adverse effect on the competitor portfolio. The abnormal returns for below-median leverage withdrawals all exhibit statistical significance, except in the [–10; 5] window. As is the case with industry concentration, the drop begins a couple of days before the actual event, with a value of –0.87% for the [–15; 1] window. The differences of the below- and above- Intra-Industry Effects of withdrawn Initial Public Offerings - 109 - Table 4.5 Abnormal Returns of the Competitor Portfolio sorted by Industry Concentration and Leverage on the Withdrawal Date of IPOs This table presents the average competitor cumulative abnormal returns ( ) in response to the withdrawal of an IPO for different event windows. The total sample comprises all withdrawal events at the NYSE, AMEX and NASDAQ between 1996 and 2011. The IPOs have no confounding event in the same six-digit NAICS industry in the surrounding 30-day period and the prices of at least 5 listed competitors in the same industry are available. The sample has further been adjusted to include only withdrawn IPOs that have no confounding positive IPO event (filing or completion) in the surrounding 20-day window.

The parameters for the market model are estimated in the period [–250; –30], relative to the event. In order to test for statistical significance of the abnormal returns, the z-statistic from Mikkelson and Partch (1988) is used and presented in parentheses. The t-statistic for the test of difference is presented in brackets.

The longer windows show no significant difference. As proposed in H7, competitors’ reactions to a withdrawn IPO are stronger for companies with low leverage. Investors do not seem to derive industry-related information from a withdrawal by a highly leveraged company, but do so in the case of companies with low leverage. As shown above, the competitor portfolio experiences a statistically significant drop in the share price in highly concentrated industries and for filing companies with low leverage. For investors, it is also important to analyze the economic significance of the competitor reaction. The average market capitalization of a competitor company in the sample used in this study is $4.3 billion. Multiplying the average competitors’ - 110 - Intra-Industry Effects of withdrawn Initial Public Offerings cumulative abnormal return in the [–3; 3] window by the market capitalization yields an average value loss per competitor of $27.8 million for withdrawn IPOs in highly concentrated industries and an average value loss of $35.7 million for a withdrawn IPO for a company with low leverage. On an event basis, the cumulated loss around a withdrawn IPO for all competitors amounts to $1.36 billion in highly concentrated industries and $1.75 billion for a company with low leverage. These figures are economically significant and reveal the substantial impact of the intra-industry effect of a withdrawn IPO. These results reveal that not all withdrawn IPOs trigger an information effect but only IPOs in highly concentrated industries or with a low financial leverage. Further, it is important to notice that competitors do not show a positive reaction to a withdrawal in the below-median sample (for industry concentration) and in the above-median sample (for financial leverage), which would indicate a possible competitive effect, but rather show no significant reaction. These results suggest that withdrawn IPOs only exhibit a very weak competitive effect, if at all. The results are similar to those of Ferris et al. (1997), who find that the competitive effect of a bankruptcy announcement is weak at best. This is an interesting observation and shows that investors have different interpretations of a positive IPO event (i.e. a filing or completion) and a negative IPO event (i.e. a withdrawal). Previous studies report a dominating competitive effect to a positive IPO event (Hsu et al., 2010; Peller, 2011). The results of this study suggest that the information effect dominates for negative IPO events. Competitors’ investors are more concerned about the potential threat of the benefit to the firm going public and not about the information signal for the industry in the case of a positive IPO event. In contrast, in the case of a negative IPO event investors are more concerned about the implied information regarding the industry outlook and not the removal of the threat caused by the issuing firm’s benefit from going public. To sum up, the results from Section 4.5 provide evidence that a withdrawn IPO can exhibit an industry-wide effect. In this case, competitors experience a significant negative stock price reaction around the time of the withdrawal. While there is no Intra-Industry Effects of withdrawn Initial Public Offerings - 111 - observable competitor reaction upon a withdrawal, on average, the results from Sections 4.5.2 and 4.5.3 show that industry concentration and the filing company’s financial leverage, together with market sentiment, have a significant impact on how the competitors’ stock value reacts to a withdrawn IPO. 4.6 Conclusion In this study, I analyze competitors’ reactions to a withdrawn IPO within the same industry in order to test if a withdrawn IPO is merely a firm-specific event or has an industry-wide impact. I find that an equally-weighted competitor portfolio exhibits a significant negative valuation response to a withdrawn IPO. However, further analysis shows that this result is driven by confounding positive IPO events (i.e. a filing or a completion). After controlling for these confounding positive IPO events, the competitor portfolio does not show a significant reaction, on average. A possible explanation for this observation is that not all withdrawn IPOs trigger an information effect, which leads to an insignificant reaction on average. In order to further analyze the competitors’ reaction I apply a cross-sectional analysis using variables that account for industry, deal and company characteristics, as well as the market environment. In the cross-sectional model, I find that competitors’ responses are substantially driven by market sentiment. Furthermore, the analysis reveals that industry concentration has a significantly negative impact on competitors’ responses, which is in line with the hypothesis that IPO filings in industries with a high concentration have a lower withdrawal risk and therefore a withdrawal comes as a greater surprise. Further, the filing firm’s financial leverage is found to have a significant impact on the competitor portfolio. The lower the leverage, the stronger is the drop in valuation for competitors. This provides evidence for the hypothesis that companies with low leverage have a lower withdrawal risk, which makes a withdrawal more surprising. Finally, when I control for industry concentration and financial leverage, I find that a subsample of withdrawals in industries with abovemedian concentration exhibits a significantly negative competitor reaction, while the below-median subsample does not exhibit a significant reaction. For the subsample of withdrawing companies with below-median leverage, the competitors’ response is - 112 - Intra-Industry Effects of withdrawn Initial Public Offerings also significantly negative, while for the above-median subsample there is no significant reaction. This suggests that only these withdrawn IPOs with a low ex-ante withdrawal risk trigger an adverse information effect as they come as a greater surprise. Other withdrawn IPOs show no significant impact on competitors. These results suggest that the withdrawal of an IPO can have an industry-wide impact. When an IPO is surprisingly withdrawn, competitors are concerned about the implied private information on the industry outlook. My results further suggest that investors have different interpretations of a positive and a negative IPO event. After a positive IPO event, investors are more concerned about the filing company’s benefits of going public and a possible competitive advantage (Hsu et al., 2010; Peller, 2011), while after a negative IPO event, they are more concerned about what the withdrawal implies regarding the industry outlook. Overall, the results of this study contribute to and expand the literature on the intra-industry effect of an IPO. These results help competitor companies and their investors in understanding the dynamics of a withdrawn IPO in their industry and in the assessment of the opportunities and threats around the withdrawal in the industry. An interesting question for further research is whether the withdrawal of related capital market transactions, such as secondary offerings or dual listings, has a similar intra-industry effect.

Conclusion - 117 - 5 Conclusion This dissertation explores the interaction of Initial Public Offerings (IPOs) with the competitive environment by focusing on two topics concerning a company’s IPO: the survivability of the IPO in the aftermarket and the intra-industry effects of the IPO. The first topic examines the influence of product market competition on an important aspect of IPOs, namely survivability in the aftermarket. The second topic takes a different perspective by assessing how an IPO influences the competitive environment, to be more specific, the firm’s competitors. The first study (Part 2) shows the relationship between the firm’s product market competition and survival time in the aftermarket. While previous research on IPO survival has already found that factors related to firm, deal and market characteristics influence the survival time of a new company in the aftermarket, this is the first study to look at the influence of the company’s product market competition. Based on a sample of US IPOs, I use a log-logistic duration analysis model along with a Cox proportional hazard model to test the influence of the firm’s product market competition on the survival time in the aftermarket. I find that an IPO’s survival time increases with industry concentration, decreases with the degree of competitive interaction in the industry and decreases with the entry rate in the industry. I find no evidence that the firm’s market share or industry demand uncertainty have a statistically significant influence on the IPO’s survival time. The findings are robust after controlling for firm-, deal- and market-related variables as well as different underlying baseline hazard functions. The results are further confirmed using a logit discrete response model. These results show that product market competition is a further dimension to evaluate when explaining the survival chances of a newly listed company. Variables relating to firm characteristics, deal characteristics or the financial market form just one dimension of factors that affect firm survival. It is rather the interaction of these variables with product market competition that decides the firm’s success or failure. Investors should therefore take into account the competitive environment of a company when assessing the risk structure of a firm - 118 - Intra-Industry Effects of withdrawn Initial Public Offerings that is going public. Moreover, the results are also valuable for companies in their decision to go public. The second study (Part 3) looks at the intra-industry effects of completed IPOs by focusing on the IPO’s competitive effect on rival firms and the interaction with product market competition. I analyze the reactions of listed competitors in response to a filing or completion of an IPO in the same industry in order to test whether the IPO’s competitive effect on industry competitors is linked to the competitive environment. I find that industry competitors yield negative abnormal returns in response to a filing or completed IPO in their industry. This result indicates that the competitive effect dominates the positive information externalities associated with the event. By analyzing competitors’ abnormal returns, I find that the industry’s product market competition influences the IPO’s competitive effect. Industry concentration, the degree of strategic interaction and industry demand uncertainty are all found to significantly influence competitors’ abnormal returns. The weaker the competitive environment, denoted by a higher industry concentration, a lower degree of strategic interaction and a lower industry demand uncertainty, the stronger is the IPO’s competitive effect. For the industry’s entry rate, I only find minor evidence that it influences the competitive effect. I further find that the subsample of IPOs in industries that have the toughest competitive environment does not show a significant response to the IPO, whereas the subsample of IPOs in industries that have the weakest competitive environment shows a significant negative response to the IPO. A possible conclusion is that the positive information effect and the competitive effect offset each other in “tough” industries. The results present evidence that the degree of the IPO’s competitive effect depends on the competitive environment. These results are of particular interest for investors in industries that have a high likelihood of new IPOs. The results also help firms that are going public as well as firms that are facing an IPO in their industry to understand the implications of an IPO as a strategic move. The third study (Part 4) continues from Part 3 by exploring how a withdrawn IPO event affects competitors given that a successful IPO event such as the filing or completion has an industry-wide impact. Theoretically, competitors should display Conclusion - 119 - the opposite reaction as to a positive IPO event. To provide insights, I analyze competitors’ reactions to a withdrawn IPO within the same industry in order to test whether a withdrawn IPO is merely a firm-specific event or has an industry-wide impact. I find that the competitor portfolio exhibits a significant negative valuation response to a withdrawn IPO. However, further analysis shows that this result is driven by confounding positive IPO events (i.e., a filing or a completion). After controlling for these confounding positive IPO events, the competitor portfolio no longer shows a significant reaction on average. A possible explanation for this observation is that not all withdrawn IPOs trigger an information effect, which leads to a non-significant reaction on average. In order to analyze in depth the competitors’ reaction I apply a cross-sectional analysis using variables that account for industry, deal and company characteristics as well as for the market environment. In this crosssectional model, I find that competitors’ responses are substantially driven by market sentiment. Furthermore, the analysis reveals that industry concentration has a significantly negative impact on competitors’ responses, which is in line with the hypothesis that IPO filings in industries that have a high concentration have a lower withdrawal risk and therefore that a withdrawal comes as a greater surprise. Further, the withdrawing firm’s financial leverage is found to have a significant impact on the competitor portfolio. The lower the leverage, the stronger is the drop in valuation for competitors. This supports the hypothesis that companies that have low leverage have a lower ex-ante withdrawal risk, which makes a withdrawal more surprising. Finally, when I control for industry concentration and financial leverage, I find that a subsample of withdrawals in industries that have above-median concentration exhibits a significantly negative competitor reaction, while the below-median subsample does not exhibit a significant reaction. For the subsample of withdrawing companies that have below-median leverage, the competitors’ response is also significantly negative, while for the above-median subsample there is no significant reaction. These results suggest that both the filing and completion of an IPO as well as the withdrawal of an IPO have an industry-wide impact. When an IPO is surprisingly withdrawn, competitors are concerned about the implied private information on the industry outlook. My results further suggest that investors - 120 - Intra-Industry Effects of withdrawn Initial Public Offerings interpret positive and negative IPO events differently. After a positive IPO event, investors are more concerned about the filing company’s benefits of going public and the possible competitive advantage, while after a negative IPO event, they are more concerned about what the withdrawal implies regarding the industry outlook. To conclude, this dissertation supports the view that it is insufficient to interpret an IPO as merely a firm-specific event and emphasizes the importance of considering the interaction of the IPO with the competitive environment. Parts 3 and 4 provide empirical evidence that an IPO, either the completion, filing or withdrawal, has a significant impact on competitors. Going public can be a strategic move and the company considering going public as well as companies facing an IPO in their industry need to understand the implications of an IPO. This study demonstrates that IPOs have an impact on the competitive environment either by affecting the competitive balance in the industry (the competitive effect) or by signaling insights about the industry outlook (the information effect). At the same time, the competitive environment affects the IPO. Part 2 of this dissertation provides evidence that the competitive environment affects the survival chances in the aftermarket of a firm going public. For further research, it might be fruitful to consider the interaction with the competitive environment when analyzing further topics concerning a company’s IPO.
