Delegated Monitoring: the Effectiveness and Pricing of Bond Indenture Trustees Christian Andres, WHU – Otto Beisheim School of Management André Betzer, BUW – Schumpeter School of Business and Economics Peter Limbach, Karlsruhe Institute of Technology* This Draft: February 2012 Abstract: To highlight the value of delegated monitoring through bond trustees, we examine the high-yield corporate bond market where default risk is high, covenants are numerous, and market values are particularly sensitive to wealth transfers. We show that bond trustees that also act as underwriters in the low-grade bond segment, but not the market’s largest trustees, reduce firms’ at-issue bond yields by 33 to 40 basis points. Accordingly, we report significantly lower bond default and downgrade risks associated with superior monitoring by these trustees. These pricing effects remain when we control for self-selection and do not hinge on whether we solely consider trustee identity or interaction terms of trustees with covenant variables that measure necessary monitoring effort. Our results can be interpreted as evidence for informational and reputational spillover effects of banks providing several services in the high-yield market segment.

Introduction With more than 3 trillion dollars in worldwide corporate bond sales in 2009 and 2010, respectively (reported in Billings et al. 2011), the bond market is an essential source of corporate financing. The huge size and the strong growth of public debt markets in recent years may in part be explained by enhanced liquidity and diversifiability of public compared to private lending. As corporate borrowing results in agency costs due to conflicts of interest between shareholders and creditors (Jensen and Meckling 1976, Black 1976, Myers 1977, Smith and Warner 1979), monitoring becomes necessary. In this context, the alleged advantages of public debt turn out to be severe disadvantages. Dispersed ownership, investor anonymity, and bond (il)liquidity make monitoring and coordination difficult tasks (e.g. Diamond 1984). To facilitate monitoring and to mitigate collective-action problems, bond contracts contain two important ingredients: a set of covenants and an indenture trustee to monitor and enforce these covenants. The trustee generally is a large banking institution with significant revenues from business unrelated to being a trustee. According to the U.S. Trust Indenture Act (TIA) of 1939, public1 bond contracts must appoint an independent trustee that is prohibited from having any severe conflicts of interest (or in some cases “skin in the game”) such as being an obligor to the issuing firm or acting as an underwriter for the same bond issue (Johnson and Boardman 1998).2 Using a sample of U.S. non-investment-grade corporate bonds issued between January 2000 and September 2008, we provide primary empirical evidence on the effectiveness and pricing of bond trustees and the value of delegated monitoring of bond covenants. Our results suggest that bond trustees that also act as underwriters in the high-yield market, however not the market’s largest trustees, reduce firms’ at-issue bond yields by at least 33 basis points. Accordingly, we document significantly lower bond default and downgrade risks associated with superior monitoring by these trustees. We interpret our results as evidence for informational and reputational spillover effects of banks providing several services in the high-yield market segment as well as for banks’ attempts to build up relations with potential future clients whose security issues they can handle. We examine the high-yield corporate bond market to highlight the role of delegated monitoring through bond trustees. In this market segment defaults are more likely to occur, covenants are 1 Private debt issues may (and do) also have trustees (see, e.g., Smith and Warner 1979). A bank that acts as the trustee for a firm’s bonds is not precluded from being the underwriter for this firm’s future security issues. For more detailed information about trustees’ conflicts of interest, see TIA §310b, Friedman (1974). 2 1 numerous and less standardized, and issuers are more opaque. Alexander et al. (2000a) reason that due to the high default risk, the market value of these bonds is especially sensitive to wealth transfers between bondholders and shareholders. Hence, monitoring is particularly important and potentially more beneficial to investors in the low-grade segment. Furthermore, high-yield investors’ risk of default and increased losses can be considerably large if the delegated monitor shirks or accepts bribes by the firm’s stockholders to overlook covenant breaches. Issuing firms in the low-grade segment are often financially distressed and thus shareholders may have stronger incentives to bribe trustees and engage in wealth transfers. Therefore, the trustee’s capabilities of information production and monitoring as well as its reputation should particularly matter to investors in the non-investment-grade bond market. The trustee’s main duty is to represent bondholders’ interests and to act as their agent in the monitoring and enforcement of bond covenants and remedial provisions specified in the bond indenture. Other responsibilities include paying and transfer agent services, organizing bondholder meetings, the provision of monthly statements for investors, and the timely reporting of covenant breaches to investors and rating agencies. Furthermore, for its review, the trustee is provided with a draft of the indenture prior to the deal being finalized and ensures that all federal and state requirements are met. In default the trustee’s responsibilities increase within the framework given by statute and the indenture contract. Within this frame, the trust officer’s skills and expertise become essential. He must organize significant actions such as the enforcement of remedies including the acceleration of maturities, the demand for specific performance of covenants, or the suit for overdue payments.3 Although the mechanism of delegated monitoring is well founded in the economic theory, empirical research in this field is very scarce (see Beatty et al. 2010 and Datta et al. 1999 for recent evidence on cross-acceleration provisions and the cross-monitoring hypothesis). In particular, no empirical study has yet jointly analyzed the role and value of bond indenture trustees and bond covenants. This is surprising as Smith and Warner (1979) reason that the choice of the trustee is important for bondholders because reputable trustees can assure that the optimal amount of monitoring and covenant enforcement takes place. The authors hypothesize 3 For more information about the TIA and the trustee’s rights and duties, see Friedman (1974), Smith and Warner (1979), Hall (1989), Johnson and Boardman (1998), Spiotto (2008). See Schwarcz and Sergi (2008) for a recent overview of the legal literature. 2 that choosing a hard-to-bribe trustee is highly relevant for bondholders as the issuing firm’s stockholders have an incentive to bribe the trustee to overlook covenant breaches. In addition, Berlin and Loeys (1988) state that if covenants are based on imperfect information, the resulting default policies based on these covenants may be inefficient as bond contracts will tend to be either too strict or too lenient. They conclude that in this case the service of a monitoring specialist, such as a bank or trustee, may be required. Amihud et al. (2000) however call for a “supertrustee” as they argue that bond trustees are ineffective monitoring devices - a view shared by finance practitioners and scholars in the legal field (see, e.g., Schwarcz and Sergi 2008). Yet, none of these studies use data to validate their conclusions. Consequently, our paper closes this gap in the literature. We show that the trustee’s monitoring abilities and potential covenant enforcement (as captured by trustee identity and variables interacting trustee identity and covenants) are priced in corporate bond issues. Particularly, we report that when banks that also offer debt underwriting services in the high-yield bond market (denoted as ‘investment bank’ trustees) act as bond trustees, the atissue yield spreads of bonds are significantly lowered by at least 33 basis points. This effect is robust to controls for endogenous matching, covenants and reputable lead underwriters, and increases when we exclude the 10% percentile of bonds with the lowest number of covenants from our sample. Even more importantly, interaction terms of ‘investment bank’ trustees with variables for the number and diversity of bond covenants, capturing the necessary monitoring effort, also have a significantly negative impact on yield spreads. This holds for interaction terms including the total number of covenants, the number of bondholder-protective covenants, and the number of different covenant groups (following the classification in Mansi et al. 2011). These covenant variables themselves, however, do not affect initial yield spreads. Taking the average number of covenants and covenant groups into account, the overall pricing effect of delegating monitoring to a capable trustee amounts to -33 to -40 basis points. Results suggest that investors in the low-grade bond market regard ‘investment bank’ trustees as effective monitoring devices and are willing to pay for their monitoring services. Our findings are backed by results indicating that the reduction in bonds’ at-issue yield spreads reflects the ‘investment bank’ trustee’s superior monitoring abilities or potentially larger incentives to act investor-oriented that result in an above-average bond performance. Interaction terms of trustee identity and bond covenants (i.e. delegated monitoring), but not trustee identity itself (i.e. selection), significantly reduce bonds’ 3 rating downgrade and default probabilities. The number and diversity of covenants either do not affect performance or increase bonds’ rating downgrade probabilities in line with a loss of financial and operational flexibility that covenants entail. As our results further indicate that the largest, arguably most reputable (Top 3) trustees in the high-yield bond market are not priced in bond issues and have no impact on bonds’ rating performance or defaults, the following (non-exclusive) interpretations arise. First, banks that also provide underwriting services in the same market segment most probably possess more valuable information and have lower costs of information production. This can enable them to conduct more effective monitoring. This reasoning is in line with models of informational synergies and spillovers as well as the information production of banks (see, e.g., Diamond 1984, Ramakrishnan and Thakor 1984, Mester et al. 2007, Norden and Weber 2010). Second, ‘investment bank’ trustees may care for reputation spillover effects that can impact their valuable (future) underwriting business and hence act more investor-oriented. 4 These banks may have strong incentives to offer high-quality trustee services to build up relations with potential future clients demanding underwriting services and to avoid harming their overall reputation and running the risk of losing existing clients. One may argue that our results for ‘investment bank’ trustees primarily stem from the banks’ enhanced expertise in the low-grade segment that they acquired through their underwriting business. However, under the reasonable assumption that these banks incur additional costs when they act more investor-oriented and perform superior monitoring, our interpretation of reputation spillover effects appears robust. Allowing for reputational spillover effects as an alternative measure of incentives to protect reputation capital, we offer evidence in favor of Smith and Warner’s (1979) reasoning that choosing a reputable trustee can be valuable for bond investors. These spillovers to other valuable businesses may be the “skin in the game” necessary to incentivize bond trustees to act dedicated. In sum, our findings allow for the following general conclusions. First, contrary to the prevailing view among many practitioners and scholars, we show that not all bond trustees are considered ineffective monitoring devices. Second, investors in the corporate bond market are willing to pay for certain trustees as these delegated monitors positively affect bond performance. Hence, not 4 The research on reputation spillover effects is very scarce. Recently, Sialm and Tham (2011) provide evidence for spillovers of performance across different business segments of publicly traded mutual fund management companies. They show that the prior stock performance of the management company significantly affects money flows and manager turnover of the affiliated mutual funds. 4 only bondholders but also firms should care for trustee choice and monitor reputation to reduce their borrowing costs. Third, generally bond covenants need a capable surveillance and enforcement device. This result is comparable to Bhattacharya and Daouk’s (2002) finding about the enforcement of insider trading rules. The authors show that the cost of equity in a country does not respond to the introduction of insider trading laws, but significantly decreases after the first prosecution. Consequently, future research on the role of bond covenants should incorporate the bond indenture trustee and the according value of the trustee’s monitoring to bondholders to avoid an omitted variable bias and to provide a complete picture of delegated monitoring. In addition to the aforementioned analyses, this paper provides a current overview of the covenant structure of U.S. high-yield corporate bonds. Our data supports Mansi et al.’s (2011) conclusion that there is some sort of ‘herding’ in the use of bond covenants. Accordingly, we document that four groups of covenants - borrowing restrictions, payment restrictions, asset and investment restrictions, and antitakeover related covenants - are included in more than 80% (and up to 96%) of all bond indentures. Our data also suggest that the number of restrictive covenants attached to high-yield bonds has considerably increased as compared to the numbers presented in Gilson and Warner (1998) who examine high-yield bond data until 1992. The remainder of this paper is organized as follows. Section 2 presents the empirical implications and employed variables. Section 3 discusses our data and provides the reader with an overview of bond covenants in the high-yield market. Section 4 deals with the issuer-trustee matching, while sections 5 and 6 present our results found in the multivariate regressions on bond pricing and performance (i.e. defaults and rating downgrades). Conclusions follow. 2. Empirical Implications and Employed Variables A. Trustees To thoroughly motivate our research question and to interpret our results in the following, an understanding of the criticism regarding the trustee’s role and responsibilities is needed in the first place. Researchers, both in finance and in the legal field (see Amihud et al. 2000 and Schwarcz and Sergi 2008, respectively), have argued that the bond trustee is ineffective in monitoring public debt and renegotiating with investors. They blame legal frictions with regard to the trustee’s rights and liabilities as well as a too low (non performance-based) compensation for 5 this ineffectiveness. Prior to default, the trustee must only act in good faith without negligence or willful misconduct and is liable only for failure to perform in accordance with the indenture (see TIA §315a (2), Robertson 1988). Thus, trustees are not obliged by law to act as dedicated as possible. A true fiduciary standard has not generally been imposed by U.S. courts. 5 Only if default occurs, trustees must act according to the prudent man rule (see TIA §315c, Robertson 1988). However, currently there is no real guidance on what prudence means within the legal framework and as a result - but, as we believe, also due to the low compensation structure - bond trustees may on average have incentives to primarily avoid personal liability rather than to protect bondholders (see Schwarcz and Sergi 2008). With respect to trustee compensation, Johnson and Boardman (1998) document that bond indenture trustees are only paid small administration fees of less than 10,000 dollars per year.6 To our point of view, another issue is important: bond trustees are prohibited by regulation to have “skin in the game” as they are not allowed to be an obligor to the firms whose bonds they monitor. Despite this recent criticism, in their seminal paper, Smith and Warner (1979) argue that bond trustees can assure that the optimal amount of monitoring and covenant enforcement takes place. They state that after a bond has been sold, the issuing firm’s stockholders have an incentive to bribe the bond trustee to overlook covenant breaches so that they can violate the bond’s covenants and engage in wealth transfers from bondholders to stockholders. The authors suggest that bribing a trustee is expensive if the trustee is reputable and its reputation has enough value in the marketplace. Accordingly, they reason that choosing a reputable, i.e. hard-to-bribe, trustee is in the bondholders’ interest. We examine the effects of two groups of trustees that, we believe, have incentives to protect their reputation capital and are thus hard to bribe in the sense of Smith and Warner (1979). The first group we consider are the largest trustees in the high-yield bond market. For this group we measure reputation by sample market share over the study period as depicted in Table 1. The use of rankings based on study-period market share is common practice in the certification literature (e.g. Megginson and Weiss 1991), particularly in studies on bond underwriter reputation (Fang 5 Sklar (1989) concludes that: “[…] although the courts have not always imposed a true fiduciary standard, the trustee should in fact be held liable as a fiduciary” (p.42). In 2008 the New York Court of Appeals, New York’s highest court, decided that indenture trustees do not owe fiduciary duties to bondholders (Pillsbury 2011). 6 Additional up-front fees amount to another ca. 10,000 dollars (Johnson and Boardman 1998). Usually fees increase if a default has occurred. With respect to this study, the mean bond volume in our sample is 272 million dollars (see Table 4). Hence, an annual fee of 10,000 dollars is equal to less than 0.004% of the mean bond volume only. 6 2005, Livingston and Miller 2000). We examine the effect of the three largest trustees, the Bank of New York (BNY) Mellon, US Bancorp, and Wells Fargo. We call this group the Top 3 trustees. The Top 3 classification is based on the fact that the three largest trustees in the market have double-digit market shares, whereas all other trustees have considerably smaller market shares. The Top 3 trustees, accounting for a 69% market share in our sample, have incentives to protect their reputation as they have considerable market share (i.e. income) to lose.7 [Insert Table 1 about here] The second group of trustees that we are interested in are ‘investment bank’ trustees. We define ‘investment bank’ trustees as banks that offer both trustee and underwriting services in the highyield bond market. These trustees account for more than 11% market share in our sample, both by number and volume of monitored bonds. The group of ‘investment bank’ trustees consists of the following banks in our sample: Bank of America, Citigroup, Deutsche Bank, JP Morgan Chase, and Wachovia. For the sample period 2000-2008, all of these banks, except for Wachovia, were among the ten largest underwriters in the low-grade corporate bond segment (see Andres et al. 2011). 8 We consider this group because these banks may have incentives to protect their reputation as bond trustees due to potential reputation spillover effects to their valuable bond underwriting business. Hence, besides the Top 3 trustees, ‘investment bank’ trustees may also be hard to bribe as they have reputation capital at stake due to significant income generated by related business. As the provision of investment-bank services and the banking industry itself are trust based, we argue that ‘investment bank’ trustees will care for their perceived overall reputation.9 Additionally, ‘investment bank’ trustees may be more capable of monitoring high 7 This argumentation follows the basic idea of repeat business and reputation capital at stake (see, e.g., Klein and Leffler 1981, Kreps and Wilson 1982, and Booth and Smith 1986). One might argue that due to the low fees charged for trustee services, trustees may have lower incentives to protect their reputation. In their annual reports, banks frequently lump revenues from corporate trust services with those of security services (e.g. global custody). Hence, it is not possible to exactly identify banks’ revenue contributions of their corporate trust business. However, in BNY Mellon’s 2007 annual report ‘issuer services fees’ (including corporate trust services) account for 17% of total fees and other revenue. In 2005 BNY’s issuer services fees accounted for almost 14% of total fees and other revenue. 8 In our sample period, Wachovia is among the fifteen largest underwriters in the high-yield segment and even among the top ten in some of the annual league tables. We note that underwriting services are also provided by the Top 3 trustees. However, they usually do not underwrite low-grade debt. Accordingly, only Wells Fargo appears as an underwriter in a few of the annual league tables. Yet, its annual and sample period market share is negligible. 9 One might ask why some banks even offer trustee services at all given the low fee structure and the possibility of harming their reputation. We argue that banks do so for three reasons. First, offering these services yields additional stable income. Second, banks that offer underwriting services may have strong incentives to build up relations to potential future clients whose security issues they can handle. Third, banks generally learn about the issuing firms’ 7 yield bonds because they act as underwriters and corporate advisors in the low-grade segment. Providing these services, the banks most likely possess more valuable firm- and industry-specific knowledge and have lower costs of information production. This can enable them to conduct more effective monitoring. This reasoning is in line with models of informational synergies and spillovers as well as the information production of banks (see, e.g., Diamond 1984, Ramakrishnan and Thakor 1984, Bhattacharya and Thakor 1993, Mester et al. 2007, Norden and Weber 2010). Furthermore, ‘investment bank’ trustees, as a result of their underwriting business, probably have closer relations to bond investors which may facilitate coordination and probably enhance trust among bondholders and trustees. As pointed out, the literature is inconclusive regarding the question of whether bond trustees are valuable or rather ineffective monitoring devices. Employing a two-step approach in the course of this paper, we first test if the indenture trustee’s identity - capturing both its reputation and its monitoring capabilities - matters to bond investors. If so it should consequently be priced in bond issues and we would expect to find a significant pricing effect for the most reputable trustees, in line with Smith and Warner (1979). However, if trustees are generally considered ineffective monitoring devices by investors in the bond market, we should find no pricing effect of their identity, neither in connection with bond covenants nor without.10 To test the aforementioned empirical implications, we use indicator variables set to one if the indenture trustee is either one of the Top 3 trustees or if it is an ‘investment bank’ trustee.11 For robustness purposes, we also examine the effects of indicator variables for BNY and Top 5 trustees. In a second step, to assess the implications of the first analysis, we examine the trustees’ effects on bond defaults and credit rating downgrades. 12 As trustees frequently gather information about the issuing firm and monitor and enforce covenants on behalf of bondholders, this second analysis is not only borrowing behavior and have access to issuers’ inside information and industry-specific knowledge. This information may be particularly valuable for banks acting as underwriters in the high-yield market. 10 For the purpose of our study, the fact that bond trustees are not allowed to have conflicts of interest, such as being an obligor to the issuing firm or acting as an underwriter for the same bond issue, is preferable econometrically as it significantly mitigates problems of potential biases caused by lending or underwriting relationships. 11 We create a binary variable that measures reputation because a dummy variable is necessary to control for a possible self-selection bias. Moreover, using a continuous variable for reputation is not preferable econometrically as this requires the variable to measure reputation with precision and to have a constant effect on the dependent variables (see Fang 2005). Nevertheless, in some regressions we control for market share using a linear measure. 12 If certain trustees significantly affect bond performance, their identity should be priced. However, this effect may be due to selection in the acceptance of trusteeships rather than differences with regard to the trustee’s skills or reputation. We econometrically address this issue in our empirical analyses. Furthermore, we note that our focus on low-grade debt already mitigates this selection problem in the first place. 8 intuitive, but first and foremost necessary to identify the real value of delegated monitoring. To highlight the trustee’s role as a delegated monitor, we focus on the interaction of trustees and bond covenants. Therefore, we interact indicator variables capturing trustee identity with variables capturing necessary monitoring effort. These variables are the total number of covenants attached to a bond, the number of bondholder-protective covenants, and a covenant index counting the number of different groups of covenants in the bond indenture. Regarding the groups of covenants, we follow the classification in Mansi et al. (2011). We argue that if reputable bond trustees care for their reputation and perceived investor friendliness, their performance will at least not be significantly below average. In fact, banks can have strong incentives to provide above-average-quality services as trustees if they want to build up relations with potential future clients. This may particularly hold true for banks offering underwriting services. B. Control Variables We control for several variables that have been shown to significantly impact at-issue yield spreads of corporate high-yield bonds as well as bond default probability. These variables are: CALLABILITY (Livingston and Miller 2000), the issue-specific CREDIT RATING on notch level (Guedhami and Pittman 2008), FIRST-TIME ISSUERS (Gande et al. 1999), MATURITY (Helwege and Turner 1999), PUBLIC FIRMS (Livingston and Zhou 2002), RULE 144A (Fenn 2000, Livingston and Zhou 2002), SENIORITY (Fridson and Garman 1997, John et al. 2010) 13, SPLIT RATINGS (Santos 2006, Livingston and Zhou 2010), VOLUME (Alexander et al. 2000b), ZERO/STEP-UP COUPON (Fenn 2000), and the level of the BofA/ML HY Master Index over 10-year Treasuries (Fridson and Garman 1998). In addition, we control for reputable underwriters via an indicator variable set to one if at least one of the bonds’ lead underwriters is among the top 10 underwriters in the low-grade debt segment (according to annual league table data from Bloomberg). We control for underwriters for two reasons. First and foremost, we want to avoid an omitted variable bias as it has been shown that reputable underwriters significantly affect atissue bond prices (see Livingston and Miller 2000, and Fang 2005 for general evidence as well as Andres et al. 2011 for evidence on high-yield corporate bonds). Second, we want to rule out that 13 As explained in John et al. (2010), both Moody’s and Standard & Poor’s pursue a rating policy of generally notching down subordinated bonds by two (S&P) or even up to three (Moody’s) notches relative to senior bonds. As the market may disagree upon this rating practice, a correction can be reflected in the initial spread. Fridson and Garman (1997) however show that senior bonds with equal rating have higher overall default risk. 9 our results are driven by ‘tit-for-tat’ strategies among underwriting banks somehow captured by our ‘investment bank’ trustee variable.14 Table 2 contains a list of all variables used in the empirical analyses including detailed definitions; pair-wise correlations of the main variables are shown in Table 3. [Insert Tables 2 and 3 about here] 3. Data Selection, Sample Statistics, and the Covenant Structure of High-Yield Bonds Data on original U.S. high-yield corporate bonds issued by public and private firms between January 1, 2000 and September 15, 2008 (i.e. after the repeal of the Glass-Steagall Act and before the collapse of Lehman Brothers) are collected from Standard & Poor’s Capital IQ (CIQ) database.15 CIQ provides detailed issue information, including access to bond indentures in most cases. In line with the existing research on bond pricing effects (e.g. Fang 2005, Livingston and Miller 2000), we exclude convertible debt as well as bonds issued by financial institutions. We check the data using the Bloomberg database to ensure bonds are non-convertible and original speculative-grade issues. Furthermore, we exclude bond issues for which no initial issue-specific credit rating, price, or trustee information is available. We are left with a sample of 600 highyield bond issues. For the remaining bonds, variables such as the first-time issuer status, bond covenants, and the firms’ credit rating history are mainly hand-selected using CIQ and the bond indentures available therein. Despite our best efforts, we are not able to gather full information for all bonds. Data on bond covenants, for example, is available for only 586 bonds. The total number of trustees in our sample is 26. Overall, there are 352 issuing firms, i.e. each firm in our sample on average issues 1.7 bonds. Data about bond trustees and the market for bond trustee services is provided by Capital IQ and additional research on the internet. Summary statistics are provided in Table 4. [Insert Table 4 about here] 14 The correlation between the indicator variables ‘Investment Bank’ Trustee and Top 10 Underwriter is only 0.01. After the collapse of Lehman Brothers there were no high-yield bond issues for a certain period of time. Moreover, this event affected investors’ attitude towards risk and potentially their demand for covenants and monitoring. 15 10 With respect to the covenant structure of U.S. high-yield corporate bonds, Table 5 provides a detailed overview of the covenants attached to the bonds in our sample. The only study that deals with high-yield bond covenants in particular, to the best of our knowledge, is Gilson and Warner (1998). For their sample of 164 high-yield bonds issued between 1980 and 1992, the authors report that the average number of restrictive covenants is 6 (relative to 24 for bank loans). Hence, they conclude that high-yield bonds are ‘covenant-light’ debt instruments. The more recent evidence we present shows that bonds in the low-grade segment have become more restrictive in terms of covenants. Accordingly, in Panel A of Table 5 we report that the average number of restrictive covenants in our sample is 10 and the total number of covenants is 16.16 The 10% percentile of the total number of covenants is 10, indicating that there are certain types of covenants that tend to be included in almost every bond indenture. Hence, we additionally consider the distribution of certain groups of covenants in Panel B of Table 5. Following the classification in Mansi et al. (2011), we document that four groups of covenants are included in more than 80% of all bond indentures: payment restrictions, borrowing restrictions, asset and investment restrictions, and antitakeover-related covenants. We thereby corroborate Mansi et al.’s statement that there is some sort of ‘herding’ in the use of covenants. Furthermore, about 19% of all bonds include restrictions on stock issuance in their indentures. This is surprising, in particular for issuers in the low-grade segment, as these covenants may hinder firms from raising equity in bad times and hence increase their risk of bankruptcy (see Mansi et al. 2011 for further evidence). [Insert Table 5 about here] Finally, in Table 6 we analyze the bond covenant structures and issue-specific credit ratings for different groups of trustees. First, bonds monitored by one of the Top 3 trustees tend to be riskier in terms of credit ratings. The difference to bonds monitored by other trustees is almost one notch. The total number of covenants is 16.2 as compared to 15.4, i.e. bonds monitored by one of the three largest trustees on average include almost one covenant more. Also, the number of subsidiary-restrictive covenants is slightly larger. These differences are statistically significant. Second, bonds monitored by ‘investment bank’ trustees are less risky in terms of credit ratings. 16 Gilson and Warner (1998) only investigate bonds issued by firms listed on the NYSE, AMEX or NASDAQ. However, when we restrict our sample to issuers listed on the NYSE or AMEX, the average number of restrictive covenants is still 9 and the total number of covenants is 15 (detailed data for the subsample of NYSE/AMEX firms not tabulated for brevity). 11 However, the difference, though statistically significant, is only about half a notch. Regarding the covenant structure, the total number of covenants amounts to 16 for both groups of bonds. Moreover, ‘investment bank’ trustees tend to monitor bonds with a slightly larger number of bondholder-protective covenants17 (6.5 versus 6.2). The aforementioned differences suggest that bonds monitored by ‘investment bank’ and Top 3 trustees might potentially witness different atissue yield spreads. [Insert Table 6 about here] 4. Empirical Findings: The Determinants of Trustee Choice We approach the potential problem of self-selection through a Heckman (1979) two-stage procedure. Therefore, as a first step, we run probit regressions that model the trustee choice (i.e. the matching between a bond issued by a firm and the trustee that accepts to monitor it). In this context, it is not only the issuing firm that has reasons to appoint a certain trustee (e.g. a Top 3 trustee or an ‘investment bank’). As Spiotto (2008) puts it, trustees may have an incentive to review the documents prior to closing and to put bondholders’ interests first. Before accepting a trusteeship trustees should make sure that they will be able to protect bondholders and to function under the terms of the indenture (e.g. to reduce their own legal risks or minimize their effort given the low compensation for trustees). To the best of our knowledge, no study has yet examined the determinants of the indenture trustee choice. Given the observable outcomes of this matching procedure, we run four probit regressions: two for the matching of an issuer with an ‘investment bank’ trustee (specifications 1 and 2) and two for the matching of an issuer with a Top 3 trustee (specifications 3 and 4). 18 In regression specifications 2 and 4 we particularly include an indicator variable for reputable (Top 10) high-yield bond underwriters to examine 17 For the classification of bondholder-protective, issuer-restrictive, and subsidiary-restrictive covenants, we follow the classification made in the Standard and Poors’ Capital IQ database. Mansi et al. (2011) also use these categories. 18 For brevity, we do not elaborate on the variables we use in these regressions. Yet, all variables capture either the necessity for monitoring or the required effort for monitoring, or both. The values of the LR Chi-squared statistics indicate that overall the models do well in explaining the issuer-trustee matching. 12 whether they affect the probability that a reputable trustee is chosen to monitor a bond.19 Results are shown in Table 7. [Insert Table 7 about here] As our findings indicate, the significant determinants of the issuer-trustee matching are similar for both types of trustees. However, the identified driving forces turn out to inversely affect the choice of Top 3 and ‘investment bank’ trustees pointing to considerable differences between these two types of trustees. First, the coefficient of the indicator variable for public firms is statistically significant at the 1% level in both regressions. Yet, while ‘investment bank’ trustees monitor significantly larger fractions of bonds issued by stock-listed firms, Top 3 trustees, on the contrary, monitor lower fractions of bonds issued by public firms.20 Second, ‘investment bank’ trustees rather monitor lower-risk high-yield debt issues (as measured by issue-specific rating classes), while Top 3 trustees tend to monitor riskier debt issues instead. The corresponding regression coefficients for the indicator variable BB are significant at the 5% and 1% level, respectively. Third, Top 3 trustees tend to monitor considerably larger fractions of redeemable bonds and bonds issued under Rule 144A. The first-time issuer status or other bond-specific features such as volume and maturity do not have an impact on the issuer-trustee matching. Finally, reputable underwriters do not affect the probability that reputable bond trustees are chosen and, in particular, that other underwriting banks act as bond trustees (see regression specification 2). Hence, we conclude that trustee reputation is not part of the underwriting standards of reputable banks (in line with practitioners’ statements). Furthermore, employing issuer-cluster or year-cluster robust standard errors does not considerably change the results. Yet, when we use year-clustered standard errors the total number of covenants attached to a bond significantly (at the 5% level) increases the probability that an ‘investment bank’ trustee monitors the bond. 5. Empirical Findings: Trustee Identity and Initial Pricing 19 This additional check is conducted for two reasons: to examine whether the choice of a reputable trustee can be interpreted as an underwriting standard of reputable underwriters and to address the possibility of underwriter relations and ‘tit-for-tat’ strategies among underwriting banks and ‘investment bank’ trustees. 20 As public firms more frequently issue securities (such as corporate bonds), this finding is in line with our reasoning that banks that also offer underwriting services (in the high-yield segment) may want to build up relations with potential future clients whose security issues they can probably handle. 13 A. Econometric Testing This section investigates whether the bond trustee’s identity/reputation and the control variables outlined in section 2 significantly affect firms’ borrowing costs as measured by the at-issue benchmark spread. In line with other studies on bond pricing effects (Guedhami and Pittman 2008, Fang 2005), we use the bonds’ at-issue yield spreads to U.S. Treasuries with similar maturity at the same date. To address the issue of self-selection regarding bond trustee choice (comparable to the selection problem of reputable underwriters acting as certifiers in bond issues, see, e.g., Fang 2005), we use a Heckman (1979) two-stage approach as recently employed in Ross (2010) and McCahery and Schwienbacher (2010).21 We may merely measure a clientele effect for a certain group of trustees if the potential problem of self-selection is significant and not controlled for. The approach requires estimating selection equations in the first step (as reported in section 4). From these regressions (specifications 1 and 3) we obtain inverse Mills ratios for the trustee choice that are included in the following equation:22 Benchmark spreadi = c0 + c1 Trusteei + …Controls…+ ei Following McCahery and Schwienbacher (2010) and Gatti et al. (2008), we first run the regression model using the standard OLS approach to have a benchmark. If the selection problem is not significant, we can basically rely on our OLS results. In the regressions we use both White (1980) heteroscedasticity-robust and industry-cluster robust (clusters: two-digit SIC codes) standard errors. The regression coefficients of the main variables are significant on conventional levels irrespective of the choice of standard errors. Some regressions include controls for industries (first-digit SIC codes) and years. Results are summarized in Table 8. [Insert Table 8 about here] B. Trustee Variables The results in Table 8 suggest that the Top 3 trustees are not considered effective monitoring devices by high-yield bond investors and accordingly do not have an impact on the issuing firms’ 21 The Heckman two-step approach is also used in Gatti et al. (2008) and Puri (1996). A detailed description of how the Heckman model can be used to correct for the problem of selection bias is given in Briggs (2004). 22 The applied methodology, contrary to the more general switching regression approach, makes the (econometric) assumption that the pricing process is similar for all bonds in our sample irrespective of the trustee’s identity. 14 borrowing costs (specification 1).23 Also, when we use a linear measure for trustee market share, based on the number of monitored bonds, the corresponding regression coefficient is not significant on any conventional level (specifications 2-4 and 7). Hence, these findings support the prevalent view that bond trustees are ineffective. Yet, contrary to the aforementioned results, our findings for ‘investment bank’ trustees reveal a different picture. This type of trustee is significantly priced in high-yield bond issues and seemingly perceived as an effective monitoring device. In the following we present a detailed analysis of ‘investment bank’ trustees. As specifications 1 and 2 show, when ‘investment banks’ act as bond trustees, the at-issue bond yield spread is significantly reduced by about 33 basis points irrespective of whether we control for the issuer-trustee matching (specification 2) or not. Regression coefficients are significant at the 10% and 5% level, respectively. The inverse Mills ratio for the choice of an ‘investment bank’ trustee in specification 2 is insignificant (see also specification 4). When we restrict our sample to bonds that have more than 10 covenants (i.e. we exclude the 10% percentile of bonds by total number of covenants) in specification 3, ‘investment bank’ trustees even reduce borrowing costs by 41 basis points, significant at the 5% level.24 We do so because bonds with only a few covenants most probably have less need for monitoring and thus trustee choice may not be that important to bond investors. Our result is in line with this reasoning. Furthermore, in specifications 4-8, we focus on interaction terms of the indicator variable for ‘investment bank’ trustees and covenant variables that capture the necessary monitoring effort of bonds. We do so to get a more comprehensive picture on the value of delegated monitoring and the importance of choosing a capable bond trustee to monitor bond covenants. In each of the regressions, we control for the covenant variable of interest.25 We use three covenant variables: 23 Results for the Top 3 variable do not change when we use a Heckman two-step approach. Furthermore, our results do not change when we employ an indicator variable for BNY Mellon or Top 5 trustees in additional unreported regressions. When we run regressions with indicator variables for each of the three and five largest trustees in our sample, none of the corresponding regression coefficients is significant on conventional levels. Finally, all interaction terms of the Top 3 indicator variable and covenant variables are insignificant. 24 We do not find a potential indication of a linear relation between the number of covenants and the pricing effect of ‘investment bank’ trustees. When we examine only bonds with more than 17 covenants (i.e. the 50% percentile), the coefficient of the trustee variable is about -33 basis points and significant at the 10% level. 25 Additional controls for the indicator variable ‘investment bank’ trustee or interaction terms of covenant variables with a dummy for the case in which there is no ‘investment bank’ trustee are not shown in the regressions (except for specification 6 in Table 8) because the pair-wise correlations with the employed interaction terms are very high (by far exceeding 50%, see Table 3). However, additionally controlling for these variables, the interaction terms we use in Table 8 remain significant in most cases, while the control variables are either insignificant or also significant. Doing so, variance inflation factors by far exceed critical levels (also in specification 6). 15 the total number of covenants attached to a bond, the number of bondholder-protective covenants, and a covenant index for the number of different groups of covenants attached to a bond (as shown in Table 5B). Considering the interaction terms, the pricing effect per number or group of covenants is -2.5, -6.2, and -8.7 basis points, respectively. The regression coefficients of the interaction terms are significant at the 5% level in specifications 4, 5 and 8, and at the 10% level in specifications 6 and 7. Except for specification 6 where the total number of covenants has a significantly positive impact on at-issue yield spreads, the covenant variables themselves do not considerably affect firms’ borrowing costs. Taking the average number of covenants and covenant groups into account, the overall pricing effect of delegating monitoring to ‘investment bank’ trustees amounts to -33 to -40 basis points. Isolating the effect of delegated monitoring of bond covenants on yield spreads, the analysis in specification 6 documents a pricing effect for investment bank trustees acting as covenant monitors of about -52 basis points (for bonds with an average number of covenants (16)). In sum, results indicate that investors in the low-grade bond market regard ‘investment bank’ trustees as effective monitoring devices and are willing to pay for their superior monitoring services. Our findings that Top 3 trustees and trustees’ market shares measured linearly do not affect at-issue yield spreads support our reasoning that ‘investment banks’ have incentives to conduct higher-quality services and signal investor orientation to avoid negative spillovers to their underwriting business and to build up relations with potential future clients in the underwriting market. 26 Following this interpretation, reputational spillover effects can be understood as the “skin in the game” necessary to incentivize bond trustees to act dedicated (i.e. the incentives point of view). Our results are also in line with the reasoning that banks that provide several services in a market segment can benefit from informational spillovers or synergy effects enabling them to act as superior monitors (i.e. the capabilities point of view). C. Robustness For robustness purposes, we conduct the following additional analyses that are not reported for brevity. First, the significant pricing effect of ‘investment bank’ trustees remains significant when we control for the yield differential of 10-year to 3-month Treasuries (Fridson and Garman 1998) 26 One may even reason that building up a reputation as an investor-friendly bank - by acting dedicated on behalf of bondholders - can positively affect a bank’s credibility as a certifier/underwriter. 16 or for the presence of certain types of covenants (following the classification as shown in Table 5B). Second, when we include additional fundamental data (retrieved from Capital IQ) for the issuing firms (i.e. total assets, leverage, and EBITDA margin for the year prior to the bond issue) in the displayed regressions, our main variables remain significant in specifications 2-4, 6 and 8. As we examine both public and private firms, we cannot use fundamental data for all firms in our sample. Hence, regressions including firm-specific financial data are based on a maximum of 493 observations. Third, examining only bonds issued by stock-listed firms, firms listed on the NYSE or AMEX, repeated issuers, or those bonds underwritten by Top 10 underwriters, the regression coefficient of our variable for ‘investment bank’ trustee remains significant. Fourth, using yearclustered standard errors, the regression coefficients of our main variables remain statistically significant in all regressions. Finally, when we use interaction terms of ‘investment bank’ trustees with the number of issuer-restrictive or subsidiary-restrictive covenants, the coefficients of these variables are also negative and significant. D. Control Variables As expected, the regression coefficient of the variable Rating is significant at the 1% level in all regression models. The pricing effect amounts to -38 to -44 basis points. Also, the coefficient of the variable Split Rating is significant at least at the 5% level and amounts to 22-24 basis points in all full-sample regressions. We thereby corroborate the findings in Santos (2006) and Livingston and Zhou (2010) who document that split credit ratings have a significantly positive effect on bond yields. As expected and shown in the earlier literature, reputable (Top 10) underwriters significantly reduce firms’ at-issue borrowing costs by at least 50 basis points.27 In addition, results for the regression coefficients of the variables HY Index Spread, Subordinate, and Zero/Step-up Coupon are also in line with the literature. All coefficients are significant at the 1% level in all regressions. The coefficient of the variable Subordinate amounts to at least -51 basis points in the full-sample regressions. This result lends further evidence to the findings reported in John et al. (2010) and Fridson and Garman (1998, 1997). The coefficient of the Zero/Step-up Coupon dummy is considerably larger than the coefficient on the same variable in Fenn (2000) - between 167 and 186 basis points as compared to 65 basis points - providing even 27 We acknowledge that we do not use more sophisticated approaches (such as a Heckman or switching regression approach) to examine the effects of underwriters as we use the Top 10 underwriter variable only as a control variable. Employing a Top 10 variable based on sample period market share (instead of annual market share) does not significantly change our results. 17 stronger evidence for the interpretation that this premium reflects the value of the firm’s default option. Furthermore, we report that public firms have significantly lower borrowing costs of at least -52 basis points. This pricing effect is significant at the 1% level throughout all regressions and roughly 30 basis points larger than in Livingston and Zhou (2002), attributable to our focus on low-grade debt. Our findings for the first-time issuer status are in line with previous work such as Gande et al. (1999). The variable’s coefficient is positive and at least significant at the 10% level. The pricing effect amounts to 24 to 26 basis points in all full-sample regressions. With respect to the bonds’ maturity and volume, our results support the previous findings in Alexander et al. (2000b), who document a significantly negative relation between bond volume and yield spreads, and in Helwege and Turner (1999) and Guedhami and Pittman (2008) who find that maturity considerably affects initial bond prices. Particularly, Helwege and Turner (1999) document that less risky firms in the high-yield bond market issue longer-maturity debt. Finally, we present recent evidence on the empirical question of the impact of SEC’s Rule 144A on the pricing of corporate bonds. We document a positive pricing effect between 24 and 28 basis points significant at least at the 10% level when using industry-clustered standard errors. Hence, our results offer evidence in favor of Fenn’s (2000) inadequate-disclosure hypothesis. 6. Empirical Findings: The Impact of Trustees on Bond Defaults and Rating Downgrades In this section, we examine whether the significant price effect of ‘investment bank’ trustees found in the previous analysis is backed by a better performance of the bonds monitored by these trustees. To measure bond performance, we use two indicator variables. The first variable is set to one if a bond defaults within the sample period or thereafter (as reported in Capital IQ). Our control period for default ends after the first quarter of 2010. As bond defaults are quite rare, we use a second variable that is set to one if a bond’s first rating action is a downgrade (as opposed to an upgrade). As shown in several studies, such as Güttler and Wahrenburg (2007) and Lando and Skødeberg (2002), credit ratings exhibit positive serial correlation, and hence a higher default risk, when the initial rating change is a downgrade. Accordingly, the existing literature shows that rating downgrades, as opposed to upgrades (in most studies), have a significant negative effect on bond prices (Wansley et al. 1992, Hand et al. 1992, Hite and Warga 1997). We also find a strong tendency of further rating changes in the direction of the first rating change when we 18 scan our sample. To examine the role and value of delegated monitoring through bond trustees, we run probit regressions with the aforementioned indicator variables as our dependent variables. In the regressions, we focus on the effects of the interaction terms of trustee and covenant variables to highlight the role of trustees as delegated monitors. We use White-robust and industry-clustered standard errors in the regressions. The results of our main variables remain significant in all regressions irrespective of the type of standard error we use. Regression results are shown in Table 9. [Insert Table 9 about here] Regarding the impact of bond trustees on the probability of bond default, we document that neither a variable interacting the Top 3 Trustee variable with the total number of covenants (specification 1) nor our linear measure of trustee market share (specification 3) affect default probability. Furthermore, neither the total number of covenants nor the number of bondholderprotective covenants or the fraction of bondholder-protective to all covenants have a significant impact on defaults. These findings are in line with the insignificant effects that these variables have on bond pricing (as reported in section 5). We do not provide regression results for ‘investment bank’ trustees, because none of the bonds monitored by an ‘investment bank’ witnessed a default over the examined period. With respect to the number of defaulted bonds, those monitored by one of the Top 3 trustees account for 50% of all defaulted bonds in our sample. This is less than expected as the three largest trustees monitor 69% of all bonds in our sample. As the number of bonds monitored by ‘investment banks’ amounts to 11% of the sample, we would have expected the fraction of defaulted bonds monitored by ‘investment bank’ trustees to be at least larger than zero percent. When we interact the number of bondholder-protective covenants with an indicator variable set to one if the bond is not monitored by an ‘investment bank’ trustee (specification 2), the corresponding regression coefficient is positive and significant at the 5% level. The aforementioned results already point to the superior monitoring skills of ‘investment bank’ trustees. Therefore, in the following, our findings for the effect of trustee identity on the rating downgrade probabilities of the bonds in our sample (specifications 4-8) will reveal more evidence on the monitoring capabilities (or incentives) of ‘investment bank’ trustees and the effects of bond covenants on bond performance. 19 The regression coefficients of the interaction terms of ‘investment bank’ trustees with the total number of covenants (specifications 4 and 5) and the number of bondholder-protective covenants (specification 6) are negative and significant. The significance level is 5% in specification 4 and 10% in the two other regressions. Moreover, the interaction term of ‘investment bank’ trustees and the covenant index (specification 7) is negative but insignificant. Furthermore, trustee identity itself does not impact bond downgrade probability as shown in specification 8. This finding indicates that the better performance of bonds monitored by ‘investment bank’ trustees is the result of superior monitoring rather than selection in the acceptance of trusteeships. Moreover, as shown in specifications 4, 5 and 8, the total number of covenants significantly increases bonds’ downgrade probabilities at least at the 5% level. Also the number of different groups of covenants (the covenant index) has a positive impact on downgrade probability. The effect of covenants can be explained within the scope of the trade-off theory (see, e.g., Malitz 1986, Billet et al. 2007, Chava et al. 2010) and the loss of financial and operational flexibility that covenants entail. Apparently, the documented phenomenon of covenant ‘herding’ (Mansi et al. 2011), leading to a large number of covenants that are attached to a bond, on average has a negative impact on high-yield bonds’ performance and is neither in the interest of issuing firms nor of bond investors. In sum, our results suggest the following. First, delegating the monitoring and enforcement of covenants to a capable (or more incentivized) trustee is important for both firms and investors in the high-yield bond market as it can reduce the probability of bond defaults and rating downgrades. Second, the significant pricing effect of ‘investment bank’ trustees found in the previous section is backed by an enhanced performance of the bonds monitored by these trustees. With regard to the control variables used in this analysis, we find that if the first rating action of a bond is downgrade, the bond’s default probability is increased significantly at the 1% level. This result points to the importance of our rating downgrade variable and corroborates the empirical studies mentioned earlier in this section. Moreover, we document that bonds with a higher credit rating have a lower probability of default but a higher probability of witnessing a credit rating downgrade.28 The corresponding coefficient of the variable Rating is significant at the 1% level throughout all regressions. This finding lends further evidence to our conclusion that ‘investment 28 It is not in the focus of this study to interpret this finding. However, higher downgrade probabilities of better-rated bonds can be due simply to a higher downside potential of these bonds or could be the result of rating inflation. 20 bank’ trustees perform superior monitoring as we have shown in section 4 that these trustees tend to monitor bonds with better credit ratings for which the downgrade probability is even higher. The downgrade probability is also higher for bonds with shorter maturity, in line with Helwege and Turner (1999), and for bonds issued by public firms, in line with the increased financial flexibility and, on average, the larger size of these firms. Furthermore, at no surprise, we find that bond downgrades are more probable during the economic recession of the years 2000-2002. We run several robustness checks in additional unreported regressions. First, the effects of the interaction terms of ‘investment bank’ trustees and covenant variables remain significant when we control for issuing firms’ fundamental data (like in section 5, the number of observations is reduced to below 500 in this case). Second, the results of our main variables remain significant when we use year-cluster robust standard errors. Third, results also remain significant when we control for leveraged buyouts (LBOs) via an indicator variable set to one if the issuer (or parent) has been the target of an LBO in the time period of five years before to five years after the bond issue. Information about LBOs is retrieved from Capital IQ. 7. Conclusion This paper is the first to empirically investigate the effectiveness and pricing of indenture trustees acting on behalf of bondholders to monitor and enforce bond covenants. Our study is motivated by the inconclusive statements about the value of bond trustees made in the existing economic literature and the lack of studies that jointly analyze bond covenants and trustees. Examining the high-yield corporate bond market where monitoring is particularly important to investors, we contribute to the as yet very limited number of empirical studies on delegated monitoring. Our results suggest that when a bank that also offers underwriting services in the high-yield debt market acts as a bond trustee, at-issue bond yield spreads are significantly reduced by at least 33 basis points. Using variables that interact trustee identity and bond covenants, we show that investors deem these ‘investment bank’ trustees - but not the largest trustees - effective monitoring devices. Accordingly, we demonstrate that ‘investment bank’ trustees, via their superior monitoring, significantly reduce bonds’ default and particularly downgrade probabilities. We interpret our results as evidence of informational and/or reputational spillover effects of banks that provide several services in a market segment. Offering a range of services can lead to 21 informational synergies and spillovers and can enable banks to reduce their costs of information production. This may result in superior monitoring abilities of multi-product banks. Yet, also the observability of the quality of banking services provided in one market segment may increase banks’ incentives to act investor-oriented and offer high-quality services to avoid negative spillover effects on their other services. In addition, banks offering underwriting services may have incentives to act as (dedicated) bond trustees as this allows them to build up relations to firms whose subsequent security issues they may potentially handle. Therefore, although the fee level for trustee services seems to be too low to incentivize banks to offer high-quality services in general, the relatively high fees that can be earned in the future through related (debt) underwriting may provide strong incentives for ‘investment bank’ trustees to conduct aboveaverage-quality monitoring. To our understanding, related business and reputational spillovers thus may be seen as the necessary “skin in the game” that incentivizes bond trustees to act dedicated. More general, our findings indicate that investors in the high-yield bond market care and should care about the quality and reputation of the delegated monitor. The same should hold for the issuing firms because the choice of a capable (or reputable) monitor can reduce borrowing costs, in line with the predictions in Smith and Warner (1979). Furthermore, we propose that issuing firms, investors, and particularly bond underwriters should carefully select and negotiate the covenants attached to a bond indenture, because too many covenants can negatively affect bond performance. Finally, our results suggest that future research should jointly investigate the value of bond covenants and indenture trustees to avoid an omitted variable bias as we show that the surveillance and potential enforcement of covenants is highly relevant to bond investors. 22 References Alexander, G.J., A.K.

The presented classification of covenants is taken from Standard and Poor’s Capital IQ database (and is also used in Mansi et al. 2011). Percentiles refer to the total number of covenants (the corresponding standard deviation is 3.95 covenants). Covenant index is the average number of different groups of covenants (as shown in panel B) that are attached to a bond. No. of covenants total 15.9 Covenant index 3.8 No. of bondholder-protective covenants 6.3 10% Percentile 10 No. of issuer-restrictive covenants 5.7 50% Percentile 17 No. of subsidiary-restrictive covenants 4.2 90% Percentile 20 Panel B: Covenant classification according to Mansi et al. (2011) This panel displays the distribution of different groups of covenants in our sample. The presented classification and the definitions of each group of covenants follow the paper by Mansi et al. (2011). Means are reported. Borrowing restrictions 95.8% Stock issuance restrictions Asset and investment restrictions 88.4% Rating trigger covenants 1.5% Antitakeover related covenants 87.5% Profit maintenance covenants 0.7% Payment restrictions 82.6% Default related covenants 0.3% 30 18.8% Table 6: Covenants and Ratings Analyses by Trustee Identity Panel A: Covenants and Ratings Analysis by Trustee Identity (Top 3 Trustees) This table reports means of the number covenants and issue-specific ratings for bonds monitored by Top 3 trustees and bonds monitored by one of the remaining trustees. Higher values for issue-specific credit ratings mean lower default probabilities (a value of 11 is equal to a B-rating by S&P). The t-statistics for differences in means are reported.
