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.     

The Information Content of Australian Managed Fund Ratings

Abstract:  We examine the information content of managed fund ratings for Australian retail investors. Because fund ratings, premised on a quantitative-qualitative model, are highly transitory, we question whether investors formulate their investment decisions with respect to changes in ratings and whether ratings, in turn, react to fund flows. We find that information regarding fund flows can be obtained from ratings, and that rating changes can have far-reaching effects. Investors flock to newly upgraded funds while they penalize those that have been downgraded by withdrawing funds. Investors are constantly anticipating ratings revisions, particularly downgrades, and we attribute this phenomenon to the role of qualitative factors in the ratings.     

Expert reports in Australian takeovers: fees and quality

Target firms in Australian takeovers are required to commission the preparation of an independent expert report in circumstances where there is a perceived conflict of interest with the bidder. As approximately half of these reports are prepared by firms with which the target has other business dealings, concern has been expressed over the quality of these reports due to the suggestion that such reports are provided at lower fees. We examine the 191 independent expert reports provided in all 649 Australian takeover bids initiated in the period 1990 to 2000 inclusive. Using an expert-fee model, we find that the fees for reports by experts with other business dealings with the target are not lower than those of unrelated experts. In addition, the results indicate that experts with other dealings with the target provide reports with a significantly smaller valuation range, consistent with these reports being of higher, rather than lower, quality. Our findings are inconsistent with the U.S. and New Zealand experience of prohibiting audit firms from providing valuation advice in takeovers.     

The Information Content of Ratings: An Analysis of Australian Credit Default Swap Spreads

We examine the information content of Australian credit rating announcements by measuring the abnormal changes in credit default swap (CDS) spreads. CDS spreads provide a direct view of credit quality and thus should impound information quickly when investors receive new credit risk related information via a rating event. Using an event study methodology, we show that watch downs and rating upgrades contain valuable information even after controlling for sources of contamination. We find that watch downs elicit statistically significant market reactions, while subsequent downgrades are anticipated. Upgrades are associated with a significant but small abnormal reduction in CDS spreads, whereas watch ups appear to contain no new information.     

Biometric Solvency Risk for Portfolios of General Life Contracts. I. The Single-Life Multiple Decrement Case

Abstract

Solvency II splits life insurance risk into seven risk classes consisting of three biometric risks (mortality risk, longevity risk, and disability/morbidity risk) and four nonbiometric risks (lapse risk, expense risk, revision risk, and catastrophe risk). The best estimate liabilities for the biometric risks are valued with biometric life tables (mortality and disability tables), while those of the nonbiometric risks require alternative valuation methods. The present study is restricted to biometric risks encountered in traditional single-life insurance contracts with multiple causes of decrement. Based on the results of quantitative impact studies, process risk was deemed to be not significant enough to warrant an explicit calculation. It was therefore assumed to be implicitly included in the systematic/parameter risk, resulting in a less complex standard formula. For the purpose of internal models and improved risk management, it appears important to capture separately or simultaneously all risk components of biometric risks. Besides its being of interest for its own sake, this leads to a better understanding of the standard approach and its application extent. Based on a total balance sheet approach we express the liability risk solvency capital of an insurance portfolio as value-at-risk and conditional value-at-risk of the prospective liability risk understood as random present value of future cash flows at a given time. The proposed approach is then applied to determine the biometric solvency capital for a portfolio of general life contracts. Using the conditional mean and variance of a portfolio’s prospective liability risk and a gamma distribution approximation we obtain simple solvency capital formulas as well as corresponding solvency capital ratios. To account for the possibility of systematic/parameter risk, we propose either to shift the biometric life tables or to apply a stochastic biometric model, which allows for random biometric rates. A numerical illustration for a cohort of immediate life annuities in arrears reveals the importance of process risk in the assessment of longevity risk solvency capital.     

Adverse Selection and the Opaqueness of Insurers

While adverse selection problems between insureds and insurers are well known to insurance researchers, few explore adverse selection in the insurance industry from a capital markets perspective. This study examines adverse selection in the quoted prices of insurers' common stocks with a particular focus on the opacity of both asset portfolios and underwriting liabilities. We find that more opaque underwriting lines result in greater adverse selection costs for property-casualty (P-C) insurers. A similar effect is not apparent for life-health (L-H) insurers and we find no effect of asset opaqueness on adverse selection for either L-H or P-C insurers.     

寿险公司的业务同质化与风险联动性

单家机构之间的业务趋同是否是金融业系统性风险的一个来源？近些年中国单家寿险公司的产品分布和地理分布均更加分散,但是公司之间的产品分布和地理分布均有“同质化”趋势,且公司之间在赔付风险、投资风险和破产风险上的联动性均提高。对此,本文分析了寿险公司业务同质化引起风险联动性的机理,探讨了几种可能的效应。基于公司配对样本,并从时间上和地理上引入工具变量处理业务同质度的内生性,发现:(1)当两家寿险公司的产品分布从完全差别到完全相同时,它们的投资风险联动性和破产风险联动性均将提高十几个百分点;(2)产品同质度对赔付风险联动性没有显著影响;(3)地理同质化对3种风险联动性均没有显著影响。     

Disclosing Physician Ratings: Performance Effects and the Difficulty of Altering Ratings Consensus

I examine effects of a health care system's policy to publicly disclose patient ratings of its physicians. I find evidence that this policy leads to performance improvement by the disclosed, subjective ratings and also by undisclosed, objective measures of quality. These effects are consistent with multitasking theory, in that physicians respond to the disclosure by providing more of a shared input—time with patients—that benefits performance by ratings and underlying quality. I also find, as predicted by information cascade theory, that the ratings become jammed to some degree near initially disclosed values. Specifically, raters observe the pattern of initial ratings and follow suit by providing similar ratings. Finally, I find evidence that physicians anticipate rating jamming and so concentrate their effort on earlier performance in order to set a pattern of high ratings that later ratings follow. These results demonstrate that the disclosure of subjective ratings can benefit performance broadly but can also shift effort toward earlier performance.     

中国家庭偿债能力:衡量与影响因素

居民部门债务的快速增长和过度累积可能导致经济体系产生潜在的金融风险。本文以2011-2017年中国家庭金融调查(CHFS)数据为研究样本,选取了综合衡量家庭偿债能力的指标,并根据宏观层面的不良贷款率对该指标进行校准。进一步地,本文基于衡量结果分析了我国家庭偿债能力的影响因素。研究发现:第一,2011-2017年期间我国金融脆弱性家庭占比呈逐年上升趋势,且现阶段我国金融脆弱性家庭变动状况存在明显的人群异质性和地区异质性。应警惕居民部门杠杆率过快上升的透支效应和潜在风险,关注低收入家庭的偿债风险。第二,购房预期收益上升使家庭产生加杠杆行为,导致家庭过度负债从而使家庭偿债能力进一步恶化。本研究对我国居民部门的金融风险监测、评估和预警有一定启示。     

Through-the-Cycle Ratings Versus Point-in-Time Ratings and Implications of the Mapping Between Both Rating Types

The two philosophies of ratings, one that includes cyclical effects and the other that doesn't, are mirrored by the two different rating types commonly known as point-in-time (pit) and through-the-cycle (ttc). Point-in-time ratings try to evaluate the current situation of a customer by taking into account both cyclical and permanent effects. In contrast, through the-cycle ratings focus mainly on the permanent component of default risk and are nearly independent from cyclical changes in the creditworthiness of a customer. In this paper we give a review of the characteristics of both rating types and examine whether these properties can actually be observed in practice. In this context we present the results of an analysis of Standard& Poor's rating data, which show that the ratings, though being through-the-cycle, still vary in accordance with the business cycle. Another concern of this paper is the wide spread practice to map 'external' through-the-cycle ratings to 'internal' point-in-time ratings, with the purpose to enrich or validate a financial institution's internal rating database. We show that in doing so financial institutions severely misspecify customers' risk profiles and under- or overestimate costs in connection with credit pricing or capitalization. We confirm our theoretical considerations by calculating pricing quantities when using one or the other rating information.     

保险公司董事会治理、公司绩效与偿付能力

随着金融业的深入发展,金融机构的公司治理问题受到越来越多的关注。本文利用127家保险公司的公开数据,以因子分析法构建的公司绩效为中介变量,探究董事会治理对偿付能力的作用以及公司绩效的中介效应。研究发现,董事金融背景比例、董事精算背景比例和董事硕博学历比例直接对偿付能力产生影响,董事金融和精算背景比例对偿付能力有正向作用,而董事硕博学历比例对偿付能力有负向作用;董事会独立性通过公司绩效间接对偿付能力产生影响,董事会独立性对偿付能力有负向作用。

The Characteristics and Valuation of Loss Reserves of Property Casualty Insurers

This study examines characteristics and valuation of claim loss reserves of property casualty insurers. Using SEC disclosures of revisions (development) in loss reserve estimates, we document substantial serial correlation in loss reserve development, indicating that reported loss reserves do not fully reflect available information, consistent with management exercising discretion over reported loss reserves. We find that loss reserve development reported one year after the balance sheet date has significant explanatory power for firm value incremental to book value of equity and earnings, suggesting investors at least partially identify management's influence on reported loss reserves, and adjust firm values accordingly.     

The Interaction of Solvency with Liquidity and its Association with Bankruptcy Emergence

Prior research has shown that accounting information available prior to a bankruptcy is associated with the likelihood of bankruptcy. We show that additionally, the accounting information available prior to bankruptcy is associated with whether or not a firm will emerge from bankruptcy. We predict that firms that exhibit low solvency risk and high liquidity risk are most likely to emerge from bankruptcy. Firms that exhibit high solvency risk and high liquidity risk are predicted to be least likely to emerge from bankruptcy. Cross–sectionally, our results support these predictions, but our findings differ across large and small firms.     

Risk Taking and Performance of Public Insurers: An International Comparison

We investigate how investor protection, government quality, and contract enforcement affect risk taking and performance of insurance companies from around the world. We find that better investor protection results in less risk taking, as do higher quality government and greater contract enforceability. However, we find only limited evidence that these factors influence firm performance. We conclude that better overall operating environments result in less risk taking by insurers without the concomitant decline in performance. These results imply that better investor protection environments benefit policyholders and outside stockholders by preventing corporate insiders from expropriating wealth from policyholders and outside stockholders.     

The Timing and Persistence of CRA Compliance Ratings

We evaluate supervisory practices in enforcing the Community Reinvestment Act (CRA) by examining whether or not supervisors consider observable, bank-specific characteristics in (1) scheduling CRA compliance examinations and (2) determining whether, and for how long, a given CRA rating persists. Failure to confirm such a relationship would be consistent with criticism that the evaluation criteria are so vague that supervisors can essentially assign any rating they want for compliance purposes. Analysis of a sample of several thousand commercial banks, observed over a relatively stable regulatory regime, indicates that both examination scheduling and the persistence of examination ratings are associated with residential loan levels, a presumed cornerstone of the CRA, as well as other financial, regulatory and market factors. We conclude that CRA enforcement during this period reflected, at least in part, objective evaluation criteria.     

Star Ratings and the Incentives of Mutual Funds

We propose a theory of reputation to explain how investors rationally respond to mutual fund star ratings. A fund's performance is determined by its information advantage, which can be acquired but decays stochastically. Investors form beliefs about whether the fund is informed based on its past performance. We refer to such beliefs as fund reputation, which determines fund flows. As performance changes continuously, equilibrium fund reputation may take discrete values only and thus can be labeled with stars. Star upgrades thus imply reputation jumps, leading to discrete increases in flows and expected performance, although stars do not provide new information.
