The Relevance of Accounting Data in the Measurement of Credit Risk

Abstract

Option pricing theory provides a robust and theoretically sound framework for the measurement of credit risk. Assuming perfect market conditions, information relevant to the measurement of a firm’s credit risk is reflected in its equity price, with no role for accounting data. This hypothesis is tested using UK data and credit ratings as a proxy for credit risk. It is found that Merton’s distance-to-default measure is the most significant variable in the measurement of credit risk. However, it is also found that accounting variables are incrementally informative when added to a model that contains only the distance-to-default measure. The incremental informativeness of accounting data varies across industries and depends on firm size. Although it is found that the general level of credit risk depends on the state of the economy, there is no evidence to suggest that the incremental informativeness of the accounting variables depends upon macroeconomic conditions.     

The risk relevance of International Financial Reporting Standards: Evidence from Greek banks

The main purpose of the paper is to estimate market, interest rate and exchange rate risk of Greek financial institutions and to explore the relationship between market-based measures of risk and accounting variables before and after the adoption of International Financial Reporting Standards (IFRS) in order to examine whether IFRS introduction enhances the information content of accounting data. Empirical results reveal that all banks are exposed to market risk while interest rate and exchange rate risk affect them occasionally. Moreover, the IFRS introduction reinforces the explanatory ability of accounting data, on systematic and non-systematic risks. Concerning the risk-relevance of accounting ratios, liquidity measures, credibility, earnings per share and provisions for credit loss are inversely related to systematic and non-systematic risks under IFRS. Moreover, loans to total assets ratio, interest rate spread and income diversification are directly associated with market measures of risk, while bank size is negatively related to both risk measures under IFRS. Our findings imply that the fair value orientation of IFRS is responsible for the higher risk-relevance of fundamentals as opposed to the historically oriented Greek Accounting Standards (GAS).     

Liquidity risk in derivatives valuation: an improved credit proxy method

The models used to calculate post-crisis valuation adjustments, market risk and capital measures for derivatives are subject to liquidity risk due to severe lack of available information to obtain market implied model parameters. The European Banking Authority has proposed an intersection methodology to calculate a proxy CDS or Bond spread. Due to practical issues of this method, Chourdakis et al. introduce a cross-section approach. In this paper, we extend the cross-section methodology using equity returns, and show that our methodology is significantly more accurate compared to both existing methodologies, and produces more reliable, stable and robust market risk and capital measures, and credit valuation adjustment.     

Credit default swap prices as risk indicators of listed German banks

This paper explores empirically the usefulness of credit default swap (CDS) prices as market indicators. The sample of reference entities consists of large, internationally active German banks and the observation period covers 3 years. By analysing the explanatory power of three risk sources: idiosyncratic credit risk, systematic credit risk and liquidity risk, we gain important insights into modeling the dynamics of CDS spreads. The impact of systematic risk, for example, has three components; one is related to the overall state of the economy, another related to the risk of the internationally active banking sector, and the third is an unobservable systematic factor. Default probabilities, inferred from a tractable reduced form model for CDS spreads, are compared with expected default frequencies from the Moody’s KMV model. The results lend empirical support to the hypothesis that structural models can be less informative than reduced-form models of CDS spreads in the case of banks with major investment banking activities as the leverage loses explanatory power. Although the CDS market appears to have matured over the observation period, during certain periods premiums for liquidity risk can increase substantially thus limiting the value of CDS spreads as market indicators. We conclude that equity prices and CDS premia should be considered together to fully exploit the information content of both market indicators and to mitigate their respective drawbacks.

The market for credit default swaps: new insights into investors' use of accounting information?

The market for credit default swaps has developed into a well‐functioning, global multi‐trillion dollar market, wherein investors price and transfer corporate financial instruments on the basis of credit risk. This paper first summarizes the structure and growth of the market. Next, I introduce theory and evidence on how investors price credits risk and explain how the quality of financial statement information plays a unique role in the determination of credit spread. I then review the nascent empirical accounting literature on this topic. This review sheds light on several accounting research questions that might be understood better in the setting of the credit default swap market. The final section summarizes suggestions for future work.     

中债估值识别了债券信用风险吗？——基于跳跃视角的实证分析

本文以2011—2018年中国A股上市公司发行的一般公司债为样本,探究了中债估值跳跃对债券信用利差的影响及作用机制,以此说明中债估值对债券信用风险的识别作用。研究发现:中债估值跳跃能够显著提高债券信用利差,其中,中债估值上跳降低了信用利差,下跳提高了信用利差,且相对于上跳,下跳对信用利差的作用更大。异质性分析发现:中债估值跳跃对信用利差的作用在机构投资者中较大,同时在信息不对称性较严重、流动性较差及违约风险较高的债券中也较大。进一步研究发现:中债估值跳跃不仅包含了公共信息,还含有私有信息,并能改善股票分析师预测表现。本研究说明中债估值能够识别债券信用风险,具有信息含量,对于债券市场信息环境建设和系统性金融风险防范具有重要意义。     

Good disclosure doesn't cure bad accounting—Or does it?: Evaluating the case for SFAS 158

This paper investigates whether the newly required recognition of the funded status of defined benefit (DB) plans under SFAS 158 is incrementally value relevant in its adoption year (2006) relative to the corresponding amounts which were previously disclosed from both equity investor and credit rating perspectives. In equity valuation models, we use a sample of 878 firms (1756 firm years) offering DB plans in 2005 (disclosure year) and 2006 (recognition year), and find no incrementally significant association with market prices of newly recognized amounts under SFAS 158 over the same information that was disclosed pre-SFAS 158. Our credit rating tests, using a sample of 428 DB firms (856 firm years) for 2005 and 2006 also show no differential impact of recognition over disclosure. Overall, we find that equity investors price the SFAS 158-imposed pension differential while credit rating agencies do not, regardless of whether such information is recognized or disclosed in the financial statements. Our results are consistent with efficiency in both equity and credit markets with respect to pension information and suggest that SFAS 158 has not changed the way market participants in aggregate use pension-related financial statement information.     

Price discovery of subordinated credit spreads for Japanese mega-banks: Evidence from bond and credit default swap markets

This paper investigates the determinants and dynamics of subordinated credit spreads for Japanese mega-banks using the bond and credit default swap (CDS) spreads. The main findings are as follows. Subordinated bond and CDS spreads are cointegrated in most cases, and the CDS spread plays a more dominant role in price discovery than the bond spread. In addition, there are significant volatility spillovers from the CDS to bond spread. This information leadership for the CDS spread can largely be explained by stronger reactions of the CDS spread to some financial market variables and bank-specific accounting variables than the bond spread.

Value investing in credit markets

We outline a parsimonious empirical model to assess the relative usefulness of accounting- and equity market-based information to explain corporate credit spreads. The primary determinant of corporate credit spreads is the physical default probability. We compare existing accounting-based and market-based models to forecast default. We then assess whether the credit market completely incorporates this default information into credit spreads. We find that credit spreads reflect information about forecasted default rates with a significant lag. This unique evidence suggests a role for value investing in credit markets.     

Counterparty credit risk and the credit default swap market

Counterparty credit risk has become one of the highest-profile risks facing participants in the financial markets. Despite this, relatively little is known about how counterparty credit risk is actually priced. We examine this issue using an extensive proprietary data set of contemporaneous CDS transaction prices and quotes by 14 different CDS dealers selling credit protection on the same underlying firm. This unique cross-sectional data set allows us to identify directly how dealers' credit risk affects the prices of these controversial credit derivatives. We find that counterparty credit risk is priced in the CDS market. The magnitude of the effect, however, is vanishingly small and is consistent with a market structure in which participants require collateralization of swap liabilities by counterparties.     

Proportional consolidation versus the equity method: A risk measurement perspective on reporting interests in joint ventures

Under Canadian generally accepted accounting principles (GAAP), firms are required to proportionally consolidate joint venture investments, as opposed to the United States where the equity method is used. Using a sample of Canadian firms, this study investigates the relative information content of equity method and proportionally consolidated financial statement amounts for explaining market risk. This is possible for Canadian firms where detailed footnote disclosures permit the calculation of pro forma equity method amounts. The findings are surprising in that whereas proportionally consolidated financial statements are more risk relevant than equity method statements for explaining price volatility, equity method statements are more risk relevant than proportionally consolidated ones for explaining bond ratings. The findings suggest that different market participants use financial statement information differently. The study also finds that failure to disclose disaggregated joint venture accounting amounts, as is the case under US GAAP, masks information that could help market participants assess risk.     

Systemic risk measures: The simpler the better?

This paper estimates and compares two groups of high-frequency market-based systemic risk measures using European and US interbank rates, stock prices and credit derivatives data from 2004 to 2009. Measures belonging to the macro group gauge the overall tension in the financial sector and micro group measures rely on individual institution information to extract joint distress. We rank the measures using three criteria: (i) Granger causality tests, (ii) Gonzalo and Granger metric, and (iii) correlation with an index of systemic events and policy actions. We find that the best systemic measure in the macro group is the first principal component of a portfolio of Credit Default Swap (CDS) spreads whereas the best measure in the micro group is the multivariate densities computed from CDS spreads. These results suggest that the measures based on CDSs outperform measures based on interbank rates or stock market prices.     

Credit risk interconnectedness: What does the market really know?

We analyze the relation between market-based credit risk interconnectedness among banks during the crisis and the associated balance sheet linkages via funding and securities holdings. For identification, we use a proprietary dataset that has the funding positions of banks at the bank-to-bank level for 2006–2013 in conjunction with investments of banks at the security level and the credit register from Germany. We find asymmetries both cross-sectionally and over time: when banks face difficulties to raise funding, the interbank lending affects market-based bank interconnectedness. Moreover, banks with investments in securities related to troubled classes have a higher credit risk interconnectedness. Overall, our results suggest that market-based measures of interdependence can serve well as risk monitoring tools in the absence of disaggregated high-frequency bank fundamental data.     

Credit derivatives and stock return synchronicity

The role of credit default swaps (CDS) in the 2008 financial crisis has been widely debated among regulators, investors, and researchers. While CDS were blamed for destabilizing the financial system, they remain effective tools for hedging credit risk, especially for major banks, and produce positive informational externalities to market participants. This paper examines whether the introduction of CDS enhances the amount of firm-specific information impounded in stock prices. We use stock return synchronicity to measure the amount of firm-specific information reflected in stock prices, with more firm-specific information being associated with a lower level of synchronicity. We find that a firm’s stock return synchronicity decreases after the commencement of CDS trading. This finding is robust to different model specifications, synchronicity measures, and endogeneity controlling methodologies. Furthermore, the decrease in stock return synchronicity is more pronounced for CDS firms with higher credit risk. Overall, our evidence supports the positive role of CDS in improving informativeness of stock prices.     

Game changer? The impact of the VW emission-cheating scandal on the interrelation between large automakers’ equity and credit markets

This paper investigates the change in the securities market pricing behavior of 16 large, global automakers following disclosure of the Volkswagen (VW) emission-cheating scandal on September 18, 2015, when the EPA issued a notice of violation to VW, stating that VW had intentionally circumvented the US clean air rules for diesel automobile emissions. We contend that this event unblocked an informational cascade, in that much of the information was already known to outside parties, yet no significant market response occurred until the September 18 EPA notice. We also find a significant change in the evolution of equity and credit default swap (CDS) prices in the automobile industry consistent with more-informed trading in the equity market. A test of economic significance further supports this finding by showing a decrease in the profitability of a trading rule based on a predictive relation between CDS spread changes and lagged equity returns.     

The complementary relationship between financial and non-financial information in the biotechnology industry and the degree of investor sophistication

We examine whether financial and non-financial variables, separately and in tandem, are value relevant in explaining market returns, equity values and the degree of investment by sophisticated investors for a sample of drug development companies. Patent counts, number of collaborations and probability-adjusted portfolios of drugs under development are the non-financial information metrics used in this study. Earnings are the main financial information variable. We show that news about these non-financial measures is significantly associated with abnormal returns. We also find that earnings are value relevant in explaining cumulative abnormal returns and equity prices around earnings announcement dates despite the fact that R&D expenditures are large and usually expensed as incurred. We further show that non-financial information is value relevant in explaining annual returns, equity prices and degree of investment by (long-horizon) sophisticated investors. Moreover, non-financial variables are value relevant after controlling for financial variables suggesting that the two types of variables are complements.     

Credit Derivatives and the Default Risk of Large Complex Financial Institutions

This paper proposes and implements a multivariate model of the coevolution of the first and second moments of two broad credit default swap indices and the equity prices of sixteen large complex financial institutions. We use this empirical model to build a bank default risk model, in the vein of the classic Merton-type, which utilises a multi-equation framework to model forward-looking measures of market and credit risk using the credit default swap (CDS) index market as a measure of the conditions of the global credit environment. In the first step, we estimate the dynamic correlations and volatilities describing the evolution of the CDS indices and the banks’ equity prices and then impute the implied assets and their volatilities conditional on the evolution and volatility of equity. In the second step, we show that there is a substantial ‘asset shortfall’ and that substantial capital injections and/or asset insurance are required to restore the stability of our sample institutions to an acceptable level following large shocks to the aggregate level of credit risk in financial markets.     

Sovereign asset values and implications for the credit market

Using the contingent claim approach and market data on sovereign credit default swaps we assess the drivers of a country's risk perception. Deriving market-based asset values for a set of advanced economies we gain insights into the capital markets' perspectives on sovereign creditworthiness. We find the market-based asset values to be positively influenced by debt and to be an early risk indicator for economic developments. In a cross-section analysis we identify drivers of the economic risk of countries. Clustering the countries according to their debt to asset value ratios provides further insights into the market perceptions of sovereign credit risk. For example we find that the asset values of countries with higher ratios react to changes in the global equity market. Countries with a lower ratio react more to the political stability within the country.
