Empirical Evidence on the Value of Group‐Level Financial Information in Insurer Solvency Surveillance

The existing empirical research on insurer insolvency relies almost exclusively upon individual insurance company financial data, even though the insurance industry is dominated by group‐affiliated firms. This is the first study to evaluate the benefit of using group‐level data to predict insurer insolvencies for group‐affiliated insurers. The study uses financial ratios from the NAIC FAST scoring system, measured at both the company level and group level, as potential predictor variables. The results indicate that group‐level financial information substantially improves the predictive power of an insolvency prediction model relative to a model that uses only the analogous company‐level variables. In fact, the group‐level variables are found to often be substantially more powerful than company‐level variables in predicting individual insurer insolvencies. These results suggest that future insolvency analysis should, whenever feasible, include group‐level information to obtain higher predictive accuracy.     

Sub-debt Yield Spreads as Bank Risk Measures

Several recent studies have recommended greater reliance on subordinated debt as a tool to discipline bank risk taking. Some of these proposals recommend using sub-debt yield spreads as triggers for supervisory discipline under prompt corrective action (PCA). Currently such action is prompted by capital adequacy measures. This paper provides the first empirical analysis of the relative accuracy of various capital ratios and sub-debt spreads in predicting bank condition: measured as subsequent CAMEL or BOPEC ratings. The results suggest that some of the capital ratios, including the summary measure used to trigger PCA, have almost no predictive power. Sub-debt yield spreads performed slightly better than the best capital measure, the Tier-1 leverage ratio, albeit the difference is not significant. The performance of sub-debt yields satisfies an important pre-requisite for using sub-debt as a PCA trigger. However, the prediction errors are relatively high and further work to refine the measures would be desirable.     

Cost of capital and valuation in the public and private sectors: Tax,risk and debt capacity

Cost of capital and valuation differ in the private and public sectors, because taxes are a cost to the private sector but are only a transfer to the public sector. We show how to transform the after-tax private sector cost of capital into its pre-tax equivalent, for comparison with the public sector cost of capital. We establish the existence of a tax induced wedge between these two costs of capital. The wedge introduces a preference on the part of the private sector for assets with rapid tax depreciation, high debt capacity and low risk. We show that, in circumstances where an asset has identical public and private sector valuation in the absence of taxes, the tax induced difference in valuation is identical to the change in government tax receipts that results from having the asset owned by the private rather than the public sector. We provide some examples of distortions that result from failure to adjust for changes in tax revenues, and show how to effect such adjustment.     

The Role of RBC,Hurricane Exposure,Bond Portfolio Duration,and Macroeconomic and Industry‐wide Factors in Property–Liability Insolvency Prediction

This research analyzes the performance of the risk‐based capital (RBC) ratio and other variables in predicting insolvencies in the property–liability insurance industry during the period 1994–2008. The results indicate that the accuracy of the RBC ratio in predicting insolvencies is inconsistent over time and that some previously tested financial ratios that are part of the FAST system do not always reliably predict insurer insolvency. In addition, the insolvency propensity is found to be significantly related to an insurer's hurricane prone area exposure, changes in interest rates, the industry‐wide combined ratio, and the industry‐wide Herfindahl index of premiums written.     

Private sector share of external debt and financial stability: Evidence from bank loans

In the last two decades, the private sector has contracted a substantially larger share in the total amount of foreign-currency international debt (private sector share of external debt), especially in developing countries. In this paper, I empirically examine the effect of this phenomenon on bank loan prices. I find that the private sector share of external debt negatively and significantly impacts the price of bank loans. This result supports the hypothesis that private sector debt contributes to international financial stability to a greater degree than sovereign debt. Nevertheless, this impact is canceled out in the presence of fixed exchange regimes that are unsuitable with respect to fundamentals. In such circumstances, the private sector may take advantage of capital market distortions that are maintained by official authorities and thus exposes the country to further financial instability. Additional results corroborate the observation that the gain in financial stability stems from more efficient use of funds and reduced monitoring costs.     

A DISCRETE-VALUED RISK FUNCTION FOR MODELLING FINANCIAL DISTRESS IN PRIVATE AUSTRALIAN COMPANIES

This paper emphasises the inappropriateness of continuous measure predictors for both the logit and MDA models when dealing with the measurement errors that exist in much of the private company data used to model financial distress in that sector. Also, it is argued that the step function logit model that we get as a consequence of the necessity to categorise the predictors, may be more appropriate in explaining underlying nonlinear behaviour of firms at risk than the usual continuous response linear function. Within this context, the two models are compared using data from 140 private Australian companies. A logit model based on only three discrete-valued ratios gave an overall accuracy rate comparable to that of an existing continuous-valued multiple discriminant analysis (MDA) model based on six ratios. Of interest is the very different order of significance of the predictor ratios in the two models although neither model remains trustworthy for predictive purposes.     

Private Equity,Buy‐outs and Insolvency Risk

Private equity restructuring using debt has been criticized for increasing financial distress and bankruptcy especially following the financial crisis. We build a unique dataset comprising the population of over 9 million firm‐year observations and 153,000 insolvencies during the period 1995–2010. We compare the insolvency hazard of the spectrum of buy‐out types within the corporate population over time and investigate the risk profile of the companies pre‐buy‐out. Controlling for size, age, sector and macro‐economic conditions, private‐equity backed buy‐outs are no more prone to insolvency than non‐buy‐outs or other types of management buy‐ins. Moreover, leverage is not the characteristic that distinguishes failed buy‐outs from those surviving.     

Government investment and the stock market

High rates of government investment in public sector capital forecast high risk premiums both at the aggregate and firm-level. This result is in sharp contrast with the well-documented negative relationship between the private sector investment rate and risk premiums. To explain the empirical findings, we extend the neoclassical q-theory model of investment and specify public sector capital as an additional input in the firm's technology. We show that the model can quantitatively replicate the empirical facts with reasonable parameter values if public sector capital increases the marginal productivity of private inputs.     

Risk in Banking and Capital Regulation

This paper investigates the role of bank capital regulation in risk control. It is known that banks choose portfolios of higher risk because of inefficiently priced deposit insurance. Bank capital regulation is a way to redress this bias toward risk. Utilizing the mean-variance model, the following results are shown: (a) the use of simple capital ratios in regulation is an ineffective means to bound the insolvency risk of banks; (b) as a solution to problems of the capital ratio regulation, the “theoretically correct” risk weights under the risk-based capital plan are explicitly derived; and (c) the “theoretically correct” risk weights are restrictions on asset composition, which alters the optimal portfolio choice of banking firms.     

Risk-based capital requirements for mortgage loans

We contribute to the debate over the reform of the Basel Accord by developing risk-based capital requirements for mortgage loans held in portfolio by financial intermediaries. Our approach employs simulation of both economic variables that affect default incidence and conditional loss probability distributions. Results indicate that appropriate capital charges for credit risk vary substantially with loan characteristics and portfolio geographic diversification. Hence, rules that offer little risk differentiation, including the current Basel I regime and “standardized” approach proposed in Basel II result in significant divergence between regulatory and economic capital. These results highlight the incentive problems inherent in simplified methods of capital regulation.     

Application of Coherent Risk Measures to Capital Requirements in Insurance

Risk measurements go hand in hand with setting of capital minima by companies as well as by regulators. We review the properties of coherent risk measures and examine their implications for capital requirement in insurance. We also comment on the specific risk-based capital computations.     

ACCOUNTING DETERMINED AND MARKET DETERMNED RISK MEASURES: SOME TESTS OF ASSOCIATION AND PREDICTIVE ABILITY

This paper examines the degree of association between certain measures of risk that commonly feature in the accounting literature, and the β coefficient, the risk measure given by the capital asset pricing model. Tests were applied to a subset of New Zealand listed public company securities. A weak association was found. Tests of the predictive ability of an accounting based regression model showed that its performance was inferior to other commonly assumed predictive models.     

The typology of partial credit guarantee funds around the world

This paper presents data on 76 partial credit guarantee schemes across 46 developed and developing countries. Based on theory, we discuss different organizational features of credit guarantee schemes and their variation across countries. We focus on the respective role of government and private sector and different pricing and risk reduction tools and how they are correlated across countries. We find that government has an important role to play in funding and management, but less so in risk assessment and recovery. There is a surprisingly low use of risk-based pricing and limited use of risk management mechanisms.     

Syndicated loan spreads and the composition of the syndicate

During the past decade, non-bank institutional investors are increasingly taking larger roles in the corporate lending than they historically have played. These non-bank institutional lenders typically have higher required rates of return than banks, but invest in the same loan facilities. In a sample of 20,031 leveraged loan facilities originated between 1997 and 2007, facilities including a non-bank institution in their syndicates have higher spreads than otherwise identical bank-only facilities. Contrary to risk-based explanations of this finding, non-bank facilities are priced with premiums relative to bank-only facilities in the same loan package. These non-bank premiums are substantially larger when a hedge or private equity fund is one of the syndicate members. Consistent with the notion that firms are willing to pay a premium when loan facilities are particularly important to them, the non-bank premiums are larger when borrowing firms face financial constraints and when capital is less available from banks.     

Capital requirements under the credit risk-based framework

This work aims to study the hypothesis of lower capitalization of banks under the risk-based rules introduced in Basel II. In this sense, an assessment of the impact of these rules on the capital requirements for non-financial firms’ credit risk is performed. A comparison with Basel I is presented and intervals of variation for the risk drivers such that capital requirements exceed the ones under Basel I are established. Data for a European country supports the hypothesis of a smaller capitalization of banks under the risk-based framework, as far as credit risk in concerned.     

Keeping up with the Joneses: Changing Rating Standards and the Buildup of Capital by U.S. Property-Liability Insurers

There has been a net propensity over the last decade for the dominant rating agency of the U.S. insurance industry, A.M. Best, to downgrade property-liability insurers. This could reflect a general deteriorating credit worthiness of the industry or an increase in the performance thresholds Best's has deemed necessary to achieve a given rating class. Consistent with a recent study of corporate bond ratings, we find evidence there has been an increase in rating stringency. Specifically, we show pressure for insurers to maintain their existing ratings provides a plausible explanation of the dramatic buildup of capital in the industry during the 1990s. In addition, our analysis suggests Best's raised the bar in terms of the capital required to maintain the highest ratings differentially relative to the increase in standards they required for lower rated categories. The actual pattern of capital buildup across firms in different rating categories is consistent with an attempt by high quality firms to defend these ratings.     

Are non-risk based capital requirements for insurance companies binding?

We investigate whether insurers base their solvency margins on risk factors even when operating under a supervisory regime where minimum solvency requirements do not fully take such risk factors into account. To do this, we use a dataset of about 350 Dutch insurers from all major lines of business during the pre-Solvency II period 1995–2005. We find that the levels of insurers’ actual solvency margins are related to their risk characteristics and not to regulatory solvency requirements. Consequently, the vast majority of insurers hold much more capital than required, i.e. non-risk based capital requirements generally are not binding. Requirements are found to affect solvency adjustment behaviour, though. More specifically, below-target capital ratios are raised most rapidly by those insurers whose targets are relatively close to the regulatory minimum. One implication from our results is that, because insurers already follow a risk-based approach, the transition to the new European regulatory framework, Solvency II, is likely to be smooth.     

Risk-based capital standards, deposit insurance, and procyclicality

This article shows that risk-based deposit insurance premiums generate smaller procyclical effects than do risk-based capital requirements. Thus, Basel II's procyclical impact can be reduced by integrating risk-based deposit insurance. If deposit insurance is structured as a moving average of contracts, its procyclical effects can be decreased further. Empirical illustrations of this are presented for 42 banks over the period 1987 to 1996. The results confirm that lengthening the contracts' maturities intertemporally smooths premiums but raises the average premium level needed to compensate the insurer for greater systematic risk. The distribution of risk-based premiums across banks is skewed.     

The impact of prompt corrective action on the default risk of the U.S. commercial banking sector

As the Basel III reforms, which come into effect from 2012, place emphasis on default risk, assessing the impact of Prompt Corrective Action (PCA) on default risk is of practical relevance. We provide strong evidence that both the dynamic and the contemporaneous impact of the PCA-defined tier 1 risk-based capital ratio and the tier 1 leverage ratio on default risk is reduced following PCA’s introduction. We interpret this as evidence that PCA is effective in managing the default risk of the U.S. commercial banking sector.     

The two faces of social capital in private flood mitigation: opposing effects on risk perception,self-efficacy and coping capacity

Impacts of flooding are expected to increase, most notably in residential areas. As a consequence, private households are increasingly encouraged to engage in private flood mitigation complementary to public measures. Despite the growing literature on private flood mitigation, little is known about how social capital influences households’ perception of and coping with flood risks. This study draws on survey data of 226 flood-prone households in two Austrian Alpine municipalities, both recently affected by riverine flooding. We show that social capital cuts both ways: on the positive side, social capital increases perceived self-efficacy and provides critical support during and most notably after flood events. On the negative side, social capital reduces flood risk perceptions of private households. While social ties are effective when responding to and recovering from floods, the expectation of social support downplays risk, making precautionary action by households less likely. The results also show that flood-affected households receive more social support than they provide to others. In the long-run, this can lead to a problematic reciprocity imbalance, challenging the long-term stability of the interpersonal exchanges underlying social capital. Among the various sources of social support, informal social networks (neighbours, friends and relatives) provide the most important workforce in the response and recovery phase of a flood event. It is therefore crucial for flood risk management to recognise and promote the protective quality of social capital alongside conventional structural and non-structural measures.
