Reinsurance and Capital Structure: Evidence From the United Kingdom Non‐Life Insurance Industry

Using a data set consisting of statutory returns of U.K. non‐life insurers from 1985 to 2002, I find that insurers with higher leverage tend to purchase more reinsurance, and insurers with higher reinsurance dependence tend to have a higher level of debt. My results are consistent with the expected bankruptcy costs argument, agency costs theory, risk‐bearing hypothesis, and renting capital hypothesis. I also find that the impact of leverage on reinsurance will be weaker for insurers that use more derivatives than those that use less. Moreover, high levels of derivative use increase the leverage gains attributable to reinsurance.     

Effects of Risk Management on Cost Efficiency and Cost Function of the U.S. Property and Liability Insurers

Abstract

This paper adopts the one-step stochastic frontier approach to investigate the impact of risk management tools of derivatives and reinsurance on cost efficiency of U.S. property-liability insurance companies. The stochastic frontier approach considers both the mean and variance of cost efficiency. The sample includes both stock and mutual insurers. Among the findings, the cost function of the entire sample carries the concavity feature, and insurers tend to use financial derivatives for firm value creation. The results also show that for the entire sample the use of derivatives enhances the mean of cost efficiency but accompanied with larger efficiency volatility. Nevertheless, the utilization of financial derivatives mitigates efficiency volatility for mutual insurers. This research provides important insights for the practice of risk management in the property-liability insurance industry.     

中国的“影子保险”:来自监管自然实验的证据

影子保险在金融稳定中扮演着重要角色,但现有文献较多关注影子银行,对影子保险关注不足。“影子保险”即保险公司通过再保险方式将保险业务转移给不受监管或者受监管较弱的关联企业的活动,这会推高其真实的杠杆水平,增加金融体系脆弱性。然而,由于影子保险的不透明性和缺少自然实验,现有研究仅基于有限数据或模型给出简单的特征事实或结构性估计,很少能从因果关系上清楚地识别影子保险活动及其机制。本文利用中国加强对中资保险公司(处理组)再保险关联交易监管的政策冲击这一自然实验,使用微观数据和双重差分方法,识别了中国金融体系中的影子保险活动。研究发现,相关监管有效降低了影子保险活动,这一效应对集团公司的影响尤为显著;在机制方面,相关监管通过影响中资保险公司资产负债表两端的结构性调整进而降低了其风险承担行为,提高了经营稳定性。本文方法对识别金融机构的监管套利和防范系统性金融风险具有一定参考意义。     

Reinsurance and corporate taxation in the United Kingdom life insurance industry

There are two main tax-related arguments regarding the use of reinsurance – the income volatility reduction and the income level enhancement arguments. The income volatility reduction argument contends that firms facing convex tax schedules have incentives to hedge in order to reduce the volatility of their annual taxable income and thereby lower expected tax liabilities [Smith, C.W., Stulz, R.M., 1985. Optimal hedging policies. Journal of Financial and Quantitative Analysis 19, 127–140]. The income level enhancement argument, advanced by Adiel [Adiel, R., 1996. Reinsurance and the management of regulatory ratios and taxes in the property–casualty insurance industry. Journal of Accounting and Economics 22, 207–240], is more specific to hedging via reinsurance. This perspective holds that reinsurance enhances current reported earnings via the receipt of reinsurance commissions and so increases tax liabilities. Consequently, insurance firms with high marginal tax rates should use less reinsurance than those with low marginal tax rates if tax matters. Prior studies using data on financial derivatives have produced mixed results on the validity of the first argument, while Adiel (1996) finds the second argument insignificant in his study of the use of reinsurance by a sample of United States (US) property–liability insurance firms. This study tests the two tax-related arguments using 1992–2001 data for a sample of United Kingdom (UK) life insurance firms. We find that UK life insurers with low before-planning marginal tax rates tend to use more reinsurance; in contrast, tax convexity is found to have no significant impact on the purchase of reinsurance and so the volatility-reduction argument is not supported.     

Leverage and reinsurance effects on loss reserves in the United Kingdom’s property–casualty insurance industry

We examine the relation between loss reserving errors, leverage and reinsurance in the UK’s property–casualty insurance industry. We find that financially weak insurers under-estimate reserves to reduce leverage, and so pre-empt costly regulatory scrutiny. However, at very high leverage, insurers over-reserve, suggesting a non-linear relation between leverage and reserving policy. We also investigate whether monitoring by reinsurers reduces reserving errors, and find that highly reinsured insurers are less likely to make loss reserve errors. However, the use of proportional reinsurance does not affect loss reserve accuracy.     

Systemic Risk in the Insurance Sector: A Review and Directions for Future Research

This article reviews the extant research on systemic risk in the insurance sector and outlines new areas of research in this field. We summarize and classify 48 theoretical and empirical research papers from both academia and practitioner organizations. The survey reveals that traditional insurance activity in the life, nonlife, and reinsurance sectors neither contributes to systemic risk nor increases insurers’ vulnerability to impairments of the financial system. However, nontraditional activities (e.g., credit default swap underwriting) might increase vulnerability, and life insurers might be more vulnerable than nonlife insurers due to higher leverage. Whether nontraditional activities also contribute to systemic risk is not entirely clear; however, the activities with the potential to contribute to systemic risk include underwriting financial derivatives and providing financial guarantees. This article is not only likely of interest to academics but also highly relevant for the industry, regulators, and policymakers.     

A Reexamination of the Corporate Demand for Reinsurance

This study examines the effect of the state of the international reinsurance market on the demand for reinsurance by U.S. insurers using data from the years 1993 through 2000. Both the overall demand for reinsurance and the utilization of foreign reinsurance by U.S. insurers are explored. In addition to supporting the findings of prior literature related to the traditional motives for the corporate demand for insurance, evidence indicates that the state of the U.S. reinsurance industry impacts the amount of reinsurance demanded by U.S. insurers. The study also investigates reasons why U.S. insurers utilize a reinsurance program composed of both U.S. and foreign reinsurers. The results indicate that the decision to utilize some percentage of foreign reinsurance is driven primarily by the financial and operational characteristics of the ceding company such as firm size, group affiliation, and organizational form. However, no support is found for the hypothesis that possible differences between the foreign and U.S. reinsurance markets impact the decision to utilize foreign reinsurance.     

THE REINSURANCE DECISION IN LIFE INSURANCE FIRMS: AN EMPIRICAL TEST OF THE RISK-BEARING HYPOTHESIS

Several explanations have been advanced in the financial economics literature to explain the reinsurance decision in insurance firms. Prominent amongst these is the risk-bearing hypothesis which holds that reinsurance is motivated by the ability of residual claimants to effectively hedge against operational risk. Since the efficiency of risk-bearing is influenced by organisational factors, such as ownership structure and firm size, the amount of reinsurance should also vary according to the characteristics of insurance firms. This study tests empirically the hypothesis that reinsurance is related to firm-specific factors. Using 1988–1993 data gathered from New Zealand's life insurance industry, a fixed-effects covariance regression model is estimated. Consistent with expectations, the results indicate that reinsurance is associated with smaller and more highly leveraged life insurance entities, and companies with greater underwriting risk. However, contrary to predictions, it also appears that it is stocks and companies with diversified production that tend to reinsure. The risk-bearing hypothesis thus receives only partial support.     

Actuarial Surplus Management in United Kingdom Life Insurance Firms

This study uses 1991–99 data gathered from the United Kingdom's life insurance industry to test empirically the notion that the reported annual surplus of a life insurer may be influenced by four firm‐specific characteristics: namely, reinsurance, output mix, organizational form and firm size. Consistent with expectations, the results indicate that the annual reported surplus is positively related to reinsurance and firm size and negatively related to the degree of product diversification. Contrary to our expectations, however, we find no evidence that proprietary (stock) life insurers tend to report higher annual surpluses than mutual life insurers.     

Systemic risk of insurers around the globe

We study the exposure and contribution of 253 international life and non-life insurers to systemic risk between 2000 and 2012. For our full sample period, we find systemic risk in the international insurance sector to be small. In contrast, the contribution of insurers to the fragility of the financial system peaked during the recent financial crisis. In our panel regressions, we find the interconnectedness of large insurers with the insurance sector to be a significant driver of the insurers’ exposure to systemic risk. In contrast, the contribution of insurers to systemic risk appears to be primarily driven by the insurers’ leverage.     

Auditor quality,audit fees,organizational structure,and risk taking in the US life insurance industry

Using a system of simultaneous equations, this study examines the relation among external audit monitoring, in the US life insurance industry. We find insurers with higher leverage risk and surplus risk are more likely to use Big‐4 auditors and to pay higher fees. In return, insurers hiring Big‐4 auditors and paying higher audit fees have lower leverage risk and surplus risk. Second, the results suggest that mutual life insurers have a higher leverage risk and surplus risk than stock life insurers. This evidence is in contrast to that for property–liability insurance companies. Third, we find insurers are less likely to hire Big‐4 auditors and to pay higher audit fees after implementation of the Sarbanes–Oxley Act (SOX). Finally, life insurers with Big‐4 auditors or paying higher audit fees are more likely to take lower risks after the implementation of SOX.     

Derivatives use and financial instrument disclosure in the extractives industry

This article documents the use and disclosure of derivatives in the Australian extractives industry. We find that derivatives are used by 23 per cent of our sample, with mitigation of commodity risk and foreign exchange risk being the most common purposes for which derivatives are used. The most common types of derivatives used in the sector for hedging purposes are forward rate agreements and options. Results indicate that derivative use is positively associated with financial risk and firm size. We also examine the relation between firm characteristics and the extent of financial instrument disclosure, using a disclosure index based on the additional requirements in IFRS 7 Financial Instruments: Disclosures. Empirical results reveal that large firms with higher leverage, which use derivatives, and are audited by a Big 4 auditor provide more extensive disclosure of financial instruments.     

Foreign exchange exposure: Evidence from the U.S. insurance industry

We study the foreign exchange exposure of U.S. insurers. The evidence shows that no systematic difference exists in the currency risk profiles of life and non-life segments within the insurance industry. This suggests that life and non-life insurers have similar risk exposure management strategies arising from similar risk pooling and financial intermediary functions. The empirical results reveal that a sizable proportion of U.S. insurers are exposed to foreign exchange movements against the seven largest U.S. trade partners in insurance services (U.K., Japan, Switzerland, Netherlands, France, Germany and Canada). Significant operational and size effects are also documented and we find that the frequency of foreign exchange exposure increases with time horizon.     

Does Reinsurance Need Reinsurers?

The reinsurance market is the secondary market for insurance risks. It has a very specific organization. Direct insurers rarely trade risks with each other. Rather, they cede part of their primary risks to specialized professional reinsurers who have no primary business. This article offers a model of equilibrium in reinsurance and capital markets in which professional reinsurers arise endogenously. Their role is to monitor primary insurers credibly, so that insurers can raise capital more easily. In equilibrium, the financial structure of primary insurers consists of a mix of reinsurance and outside capital. The comparative statics yield empirical predictions which are broadly in line with a number of stylized facts from the reinsurance market.     

Internal Versus External Capital Markets in the Insurance Industry: The Role of Reinsurance

This study compares internal and external sources of capital in the insurance industry by analyzing reinsurance activity between affiliated and unaffiliated insurers. Tests are performed using data from a large sample of property-liability insurers that are affiliated with at least one other property-liability insurer. Results indicate that while demands for internal and external reinsurance have some factors in common, there are cost-based differences in internal and external capital, as well as structural differences in the use of internal and external reinsurance. Results are consistent with previous theories related to internal versus external capital markets.     

CEO EXTRAVERSION AND CAPITAL STRUCTURE DECISIONS: THE ROLE OF FIRM DYNAMICS,PRODUCT MARKET COMPETITION,AND FINANCIAL CRISIS

Using panel data of U.S. firms, we focus on an important yet understudied facet of the chief executive officer's (CEO) personality—extraversion—and how it affects corporate capital structure decisions. We examine how this relation is moderated by financing (tax) benefits, financial crisis, firm size, growth opportunities, and collateralization. The results show that firms managed by extraverted CEOs use greater financial leverage, adjusting toward target leverage levels at a faster speed, with about half-life within a year for book and market leverage. In addition, the positive extraversion–leverage relation is enhanced for firms that are large, have greater collateralizable assets, and are more vulnerable to external shocks (financial crisis). Last, although the positive extraversion–leverage relation holds particularly when product market competition is high, the effect is attenuated for high-growth opportunity firms.     

Organizational Structure and Performance: Evidence From the Nonlife Insurance Industry in Japan

This study examines the impact of organizational structure on firm performance, incentive problems, and financial decisions in the Japanese nonlife (property‐casualty) insurance industry. Stock companies that belong to one of six horizontal keiretsu groups have lower expenses and lower levels of free cash flow than independent stock and mutual insurance companies. Keiretsu insurers also have higher profitability and higher loss ratios than independent insurers. With a limited sample size, there is some evidence that mutual insurers have higher levels of free cash flows, higher investment incomes, and lower financial leverage than their stock counterparts. Overall, empirical evidence suggests that each structure has its own comparative advantage.

Adverse Selection in Reinsurance Markets

This paper looks for evidence of adverse selection in the relationship between primary insurers and reinsurers. We test the implications of a model in which informational asymmetry—and therefore, its negative consequences—decline over time. Our tests involve a data panel consisting of U.S. property-liability insurance firms that reported to the National Association of Insurance Commissioners during the period 1993–2012. We find that the amount of reinsurance, insurer profitability, and insurer credit quality all increase with the tenure of the insurer–reinsurer relationship.     

Financial Distress in Australian General Insurers

We develop and test a statistical model to identify Australian general insurers experiencing financial distress over the 1999–2001 period. Using a logit model and two measures of financial distress we are able to predict, with reasonable confidence, the insurers more likely to be distressed. They are generally small and have low return on assets and cession ratios. Relative to holdings of liquid assets they have high levels of property and reinsurance assets, and low levels of equity holdings. They also write more overseas business, and less motor insurance and long‐tailed insurance lines, relative to fire and household insurance.
