Do managers withhold bad news from credit rating agencies?

Research documents that managers, on average, withhold bad news and emphasize good news in their public disclosures. We ask whether the same is true in their private communications with credit rating agencies. We study how rating agencies anticipate and react to public information events as a function of their access to rated firms’ private information. We show that, in terms of ratings downgrades, rating agencies exhibit relatively more anticipation and less reaction to negative (compared to positive) public information events when they have more access to private information. Our results are strongest when firms are most optimistic in their public disclosures and are not due to rating agencies focusing their efforts on downside risk. Overall, we find consistent evidence that rated firms provide less optimistic information to rating agencies in their private communications and that this information is reflected in credit ratings.

     

The Effect of Business and Financial Market Cycles on Credit Ratings: Evidence from the Last Two Decades

We analyze the effect of business and financial market cycles on credit ratings using a sample of firms from the Russell 3000 index that are rated by Standard and Poor's over the period 1986–2012. We also examine investor reaction to credit rating actions in different stages of business and financial market cycles. We document that credit rating agencies are influenced by business and financial market cycles; they assign lower credit ratings during downturns of business and financial market cycles and higher ratings during upturns. Our study is the first to find strong evidence of pro‐cyclicality in credit ratings using a long window. We also document stronger investor reaction to negative credit rating actions during downturns. Our results confirm theoretical predictions and inform regulators.     

Corporate use of derivatives and excess value of diversification

We provide a link between diversification discount and corporate use of financial derivatives. We show that diversified firms benefit from financial risk management. Our findings are consistent with the notion that derivative usage lowers information asymmetry and thereby reduces the negative valuation effects of diversification. Our evidence complements the earlier findings of both the risk management literature and diversification discount literature and is robust to controls for endogeneity and information asymmetry levels.     

Corporate financing and anticipated credit rating changes

Firm circumstances change but rating agencies may not make timely revisions to their ratings, thereby increasing information asymmetry between firms and the market. We examine whether firms time the securities market before a credit rating agency publicly reveals its decision to change a firm’s credit rating. Using quarterly data, we show that firms adjust their financing structures before credit rating downgrades are publicly revealed. Specifically, firms on average increase their debt financing by 1.29 % before the disclosure of a rating downgrade, and this increase is due to the issuance of debt rather than the repurchase of equity. In contrast, firms do not take significant financing actions before credit rating upgrades.     

Credit ratings and IPO pricing

We examine the effects of credit ratings on IPO pricing. The evidence from U.S. common share IPOs during 1986–2004 shows that when firms go public, those with credit ratings are underpriced significantly less than firms without credit ratings. Credit rating levels, however, do not have a significant effect on IPO underpricing. The existence of credit rating reduces uncertainty about firm value. It is the value certainty that matters, not the value per se. Credit ratings also reduce the degree of price revision during the bookbuilding process and the aftermarket volatility in the post-IPO period. The evidence suggests that credit ratings convey useful information in reducing value uncertainty of the issuing firms as well as information asymmetry in the IPO markets.     

Directors’ and Officers’ liability insurance and bond credit spreads: Evidence from China

Using hand-collected data on purchases of D&O insurance by Chinese listed firms for the period from 2008 to 2019, we empirically find that D&O insurance negatively associates with credit spreads. The negative relationship still holds after conducting a series of robustness tests and is not driven by the eyeball effect. We also show that D&O insurance can reduce credit spreads via the channels of internal controls, external monitoring, information asymmetry and default risk. Moreover, the negative effect of D&O insurance on credit spreads is more pronounced for non-state-owned firms, those located in regions with a low level of marketization or that employ rating agencies with a bad reputation. Our study complements the literature on the credit spreads and corporate governance.     

Is There a Difference Between Solicited and Unsolicited Bank Ratings and, If So, Why?

This paper analyses the effect of soliciting a rating on the actual outcome of bank ratings. Using two sample banks (one rated by Fitch and one rated by S&P), I find evidence that unsolicited ratings tend to be lower than solicited ones, after accounting for differences in observable bank characteristics. This downward bias does not seem to be explained by the fact that better-quality banks self-select into the solicited group. Rather, unsolicited ratings appear to be lower because they are based on public information and are therefore dependent on the quantity of public information disclosed by the banks. As a result, unsolicited ratings tend to be more conservative than solicited ratings, which incorporate both public and non-public information. While the latter result is also consistent with the fact that credit rating agencies may blackmail low-disclosure firms, the findings suggest that blackmailing—if it is actually used—is ineffective in making these firms start to pay for a rating.     

Does Information Asymmetry Explain The Diversification Discount?

We examine the diversification discount while controlling for differences in information asymmetry between diversified and nondiversified firms. We show that both diversified and nondiversified firms with higher levels of information asymmetry have discounted firm values relative to firms with lower levels of information asymmetry, although a diversification discount remains at all levels of information asymmetry. Fixed‐effect Fama‐MacBeth regressions confirm the existence of a statistically significant relation between information asymmetry proxies and excess value, but they also show that a significant diversification discount remains after controlling for differences in information asymmetry and other firm characteristics discussed in earlier studies (e.g., size, profitability, leverage, and capital constraint).     

On syndicate composition, corporate structure and the certification effect of credit ratings

We assess the relative importance of ratings versus stock exchange listings in reducing information asymmetry using a dataset of syndicated loans to public and private firms in the UK. We find that the certification effect of ratings is largest for private firms and that syndicates are smallest if firms are privately held or unrated. Moreover, we find that the marginal effect of being stock exchange listed is insignificant once these firms are rated. Exploiting the heterogeneity among lenders, we find that especially foreign bank and non-bank investors do not provide capital if firms are unrated. Our paper highlights the information produced by rating agencies as an important mechanism by which ratings improve access to capital. Our results also emphasize the importance of syndicate moral hazard on the supply of uninformed capital: bank-borrower relationships significantly increase the loan share syndicated to investors particularly if firms are not listed and unrated.     

The role of credit ratings on capital structure and its speed of adjustment: an international study

Using an international dataset, we examine the role of issuers’ credit ratings in explaining corporate leverage and the speed with which firms adjust toward their optimal level of leverage. We find that, in countries with a more market-oriented financial system, the impact of credit ratings on firms’ capital structure is more significant and that firms with a poorer credit rating adjust more rapidly. Furthermore, our results show some striking differences in the speed of adjusting capital structure between firms rated as speculative and investment grade, with the former adjusting much more rapidly. As hypothesized, those differences are statistically significant only for firms based in a more market-oriented economy.     

Market Implied Ratings and Financing Constraints: Evidence from US Firms

Financing constraints have been found to play an important role in several aspects of firm behavior, but no attention has been given to their effects on credit ratings. In this paper we analyze a unique and comprehensive data set for US firms rated by Fitch over the period 2001–07. We employ Fitch's market implied ratings derived from bond and equity prices. The analysis finds evidence that financial variables are more important in predicting credit ratings for firms likely to face financing constraints. We conclude that the financing constraint is an important dimension in the market implied ratings process. Our findings are of relevance to managers, investors and rating agencies seeking to understand the mechanism through which financing constraints affect credit ratings.     

Firstborn CEOs and credit ratings

Our study examines whether CEOs’ birth order can predict firms’ credit ratings. Consistent with studies that document a positive relationship in the general population between being firstborn and being conservative, our study finds that firms managed by firstborn CEOs tend to have higher credit ratings than those managed by later-born CEOs. Our results are robust to controlling for additional personal CEO traits, such as political identity, and to using a propensity score matching sample. A change analysis supports the causality of the firstborn effect. We suggest that return on assets and free cash flow are possible channels through which firstborn status affects credit ratings. Cross-sectional analyses show that the positive association is less (more) pronounced for firstborn CEOs who have a pilot license (run firms in less competitive industries). These results suggest that managerial conservatism may be an important factor in credit rating agencies’ credit risk assessments.     

Unsolicited Versus Solicited: Credit Ratings and Bond Yields

This paper is the first attempt to analyze Standard & Poor’s unsolicited and solicited ratings by using bond-yield data in Japan. Our findings show that there are differences in firm characteristics between firms seeking solicited ratings and those that receive unsolicited ratings. Firms with solicited ratings have less information asymmetry and are more likely to be owned by foreign investors, generate more revenue from exports, be cross-listed in the US, and have higher firm quality. But, firms with unsolicited ratings pay higher costs for debt, and their bond prices react more strongly to credit-rating changes. Yield spreads for new bonds with unsolicited ratings are higher than those with solicited ratings, because unsolicited ratings have higher information asymmetry, and investors therefore demand higher yields. We find that bond-price reactions to the announcements of unsolicited rating downgrades (upgrades) are negative (positive) and significant, while bond prices do not react significantly to solicited rating downgrades or upgrades.     

信用评级变动能反映企业真实财务信息吗?——基于财务重述的视角

本文以2007-2018年拥有主体信用评级的A股上市公司为研究对象,利用企业财务错报在未来被重述这一场景,检验主体信用评级变动能否反映企业真实财务信息。研究发现,评级机构在发债企业财务错报年显著下调了主体信用评级,而在重述公告发布年没有上述现象,这表明主体信用评级下调反映了企业的真实财务信息。在控制内生性影响后,结论仍然成立。进一步研究发现,发债企业当期财务错报涉及盈余时,主体信用评级被下调的幅度更大,说明评级机构更加关注与盈余相关的财务信息。机制分析表明,评级机构维护自身声誉是主体信用评级变动能够反映企业真实财务信息的主要机制。此外,主体信用评级被下调还导致了资本市场投资者的负面反应。本文的研究结果为主体信用评级变动反映企业真实财务信息提供了直接的证据支持,揭示了主体信用评级的信息含量,也对理解中国情境下评级机构调整主体信用评级的行为动机提供参考。     

Characteristics and Information Value of Credit Watches

We analyze credit watch and rating actions to better understand the role of credit watches in the credit rating process. We find that watch actions are more frequently prompted by specific, publicly known events than are rating actions. The likelihood that a watch action precedes a rating action varies systematically with proxies for investor demand for credit quality information and the adverse consequences of issuing a rating change prematurely. Credit watches occur more often in response to deterioration in credit quality, and issuers make concerted efforts to address the concerns that prompted down watches. Down watches are less likely than up watches to indicate the direction of the subsequent rating change. Watch announcements are associated with abnormal stock returns, indicating that credit watch actions are significant information events. Our results suggest that credit watches are informative and facilitate the stability of ratings by allowing firms to correct deficiencies and prevent downgrades.     

Initial credit ratings and earnings management

Credit rating agencies assert that they rely on financial information provided by issuers and that they value rating stability as well as accuracy. In an environment where rating agencies depend on issuer-reported information and are reluctant to adjust ratings promptly, managers of issuing firms can utilize the discretion afforded by GAAP to obtain the most favorable credit ratings. Consistent with our expectations, we find that current accruals are unusually positive and high around initial credit ratings. The increase in abnormally high accruals leading up to the initial credit rating year is followed by a reversal in the subsequent years. Multivariate regression analyses suggest that accounting accruals, abnormal current accruals in particular, are significantly positively related to initial credit ratings after controlling for several issue- and issuer-related characteristics indicative of default risk. Our results are robust to additional tests that account for endogeneity between credit ratings and earnings management, adjust for performance, and account for firms issuing debt and equity simultaneously.     

Is less information better information? Evidence from the credit rating withdrawal

This paper examines the stock market reaction to two different types of credit rating withdrawals by Moody’s. The first type of withdrawal occurs when a firm stops being rated. This happens, for example, when firms choose to no longer pay for a rating. We find that the stock market reaction depends on the information which remains available. The second type of withdrawal is due to Moody’s policy of removing the issuer rating and keeping the corporate family rating for the same firm. The corporate family rating is usually more favorable than the issuer rating. The paper shows that the removal of the issuer rating leads to positive stock market reaction. We conclude that lower disclosure of rating information is not necessarily associated with higher cost of equity. Instead, our findings emphasize the incentive for firms to engage in ratings shopping by publishing only the most favourable ratings.     

Credit ratings and the choice of payment method in mergers and acquisitions

This paper establishes that credit ratings affect the choice of payment method in mergers and acquisitions. We find that bidders holding a high rating level are more likely to use cash financing in a takeover. We attribute this finding to lower financial constraints and enhanced capability of highly rated firms to access public debt markets as implied by their higher credit quality. Our results are economically significant and robust to several firm- and deal-specific characteristics and are not sensitive to the method used to measure the likelihood of the payment choice or after controlling for potential endogeneity bias.     

Credit Ratings and Earnings Management around IPOs

This study examines the impact of having a credit rating on earnings management (EM) through accruals and real activities manipulation by initial public offering (IPO) firms. We find that firms going public with a credit rating are less likely to engage in income‐enhancing accrual‐based and real EM in the offering year. The monitoring by a credit rating agency (CRA) and the reduced information asymmetry due to the provision of a credit rating disincentivise rated issuers from managing earnings. We also suggest that the participation of a reputable auditing firm is crucial for CRAs to effectively restrain EM. Moreover, we document that for unrated issuers, at‐issue income‐increasing EM is not linked to future earnings and is negatively related to post‐issue long‐run stock performance. However, for rated issuers, at‐issue income‐increasing EM is positively associated with subsequent accounting performance and is unrelated to long‐run stock performance following the offering. The evidence indicates that managers in unrated firms generally manipulate earnings to mislead investors, while managers in rated firms tend to exercise their accounting and operating discretion for informative purposes.     

Political similarities in credit ratings

We investigate whether political similarities between credit rating agencies (CRAs) and bond issuers impact credit rating quality. We find that a higher degree of similarity of political affiliation leads to a decrease in timeliness and accuracy of downgrades prior to default events. Our finding supports the notion that CRAs tend to maintain/assign preferential ratings to politically similar firms via delaying negative signals as favourable rating activities. We further show that these politically similar firms tend to increase the proportion of donations to their favoured party following favourable credit ratings. Interestingly, this result is confined to Republican-leaning firms. The results indicate that CRAs successfully use biased credit ratings as an indirect channel of political party support. Our findings support the political similarities in credit ratings hypothesis.
