Efficiency and Demutualization: Evidence From the U.S. Life Insurance Industry in the 1980s and 1990s

This article examines the efficiency changes of U.S. life insurers before and after demutualization in the 1980s and 1990s. We use two frontier approaches (the value‐added approach and the financial intermediary approach) to measure the efficiency changes. In addition, we use Malmquist indices to investigate the efficiency and productivity change of converted life insurers over time. The results using the value‐added approach indicate that demutualized life insurers improve their efficiency before demutualization. On the other hand, the evidence using the financial intermediary approach shows the efficiency of the demutualized life insurers relative to mutual control insurers deteriorates before demutualization and improves after conversion. The difference in the results between the two approaches is due to the fact that the financial intermediary approach considers financial conditions. The results of both approaches suggest that there is no efficiency improvement after demutualization relative to stock control insurers. There is, however, efficiency improvement relative to mutual control insurers when the financial intermediary approach is used.     

On the Lack of Participating Policy Usage by Stock Insurance Companies

Stock insurers can reduce or eliminate agency conflicts between policyholders and stockholders by issuing participating insurance. Despite this benefit, most stock companies don't offer participating contracts. This study explains why. We study an equilibrium with both stock and mutual insurers in which stockholders set premiums to provide a fair expected return on their investment, and with a policyholder who chooses the insurance contract that maximizes her expected utility. We demonstrate that stockholders cannot profitably offer fully participating contracts, but can profitably offer partially participating insurance. However, when the policyholder participation fraction is high, the fair‐return premium is so large that the policyholder always prefers fully participating insurance from the mutual company. Policies with lower levels of policyholder participation are optimal for policyholders with relatively high risk aversion, though such policies are usually prohibited by insurance legislation. Thus, the reason stock insurers rarely issue participating contracts isn't because the potential benefits are small or unimportant. Rather, profitability or regulatory constraints simply prevent stock insurers from exercising those benefits in equilibrium.     

Capital Structure Decisions in the Insurance Industry: Stocks versus Mutuals

Mutual insurers generally face higher costs of raising new capital than stock insurers. Other things being equal, the higher costs of raising capital should cause mutual insurers to have higher ex ante target capital to liability ratios than stock insurers. Mutual insurers' capital ratios also should be more sensitive to income than capital ratios for stock insurers and therefore adjust more slowly toward their long-run targets. We provide evidence concerning these issues using aggregate time series data for stock and mutual insurers during 1984–1999 and a large panel data set during 1991–1998. Our regressions provide strong evidence that annual changes in capital to liability ratios are more sensitive to income for mutual insurers than for stock insurers. We also provide evidence that mutual insurers' capital ratios are on average higher than those for stock insurers after controlling for several factors that could influence capital ratios.     

Efficiency in the UK life insurance industry: Mutual firms versus proprietary firms

The paper discusses the main tenets of stakeholder theory and agency theory and goes on to analyse the relative performance of a sample of 100 mutual and proprietary life insurance companies in the UK during the period 1992–1996. The paper concludes that there is weak evidence to support the contention that mutual life insurers are relatively more cost efficient than proprietary insurers. Mutual companies in the sample perform well relative to proprietary companies in terms of annual surpluses and expenses ratios. There is also evidence that fund managers in mutual companies perform at least as well on average as those in proprietary companies.     

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.     

The Demise of the Mutual Organizational Form: An Investigation of the Life Insurance Industry

We investigate the role of organizational structure in financial services markets by examining the U.S. life insurance industry. Traditionally, stock and mutual life insurers were equally represented, but now the industry is mainly composed of stock firms. We find operational efficiency, access to capital, and tax savings are important determinants for this shift. The incentive to demutualize differs by the type of conversion: full demutualization is chosen for efficiency and access to capital reasons and partial conversion, using a mutual holding company, is chosen for tax savings. Firm operational efficiency improves after conversion. We also find the efficiency of the stock organizational form dominates that of the mutual structure during our sample period, 1995 to 2004.     

The Determinants of Financial Derivatives Use in the United Kingdom Life Insurance Industry

This paper examines the determinants of financial derivatives use in the United Kingdom life insurance industry. We estimate a probit regression model and a Heckman two-stage sample selection regression model using a sample of eighty-eight U.K. life insurers in 1995. Our results indicate that the propensity to use derivative instruments is positively related to a firm's size, leverage and international links, and negatively related to the extent of reinsurance. We also find that mutual life insurance firms have a greater propensity than stock firms to use derivatives. The positive relation with leverage and the negative relation with reinsurance support the hypothesis that U.K. life insurers use derivatives to offset risk, rather than as a speculative means of income generation. Firm size and organizational form are the main influences on the extent of financial derivatives use.     

Conversion and Efficiency Performance Changes: Evidence from the U.S. Property-Liability Insurance Industry

This study investigates whether the conversion of U.S. property-liability insurers improves their efficiency performance before and after the conversion. We estimate relative efficiency of converting insurers and control insurers using data envelopment analysis. The Malmquist analysis is also used to measure changes in efficiency pre- and post-conversion. The evidence shows that converting insurers experience larger gains in cost efficiency and total productivity change than mutual control insurers before conversion. In addition, the empirical results indicate that converting insurers improve efficiency after conversion. These results are robust with respect to both the value-added and the financial intermediary approaches. The overall results support the efficiency hypothesis proposed by Mayers and Smith (1986).     

Organizational structure,risk-based capital requirements,and the sales of downgraded bonds

Using bond downgrades as external shocks to life insurers’ asset risk, we document several findings of the impact of organizational structure and risk factors on investment risk taking. First, we find that mutual insurers and widely-held stock insurers are more likely to sell downgraded bonds than are closely-held stock insurers. Second, we find evidence that insurers are less likely to sell downgraded bonds that remain in the same rating class than bonds downgraded to a lower rating class. The result implies that insurers sell downgraded bonds mainly because of additional capital charge is imposed, not because of downgrade itself. In other words, risk factors in risk-based capital regulation do matter on life insurers’ investment risk taking. Finally, we find that life insurers might be reluctant to sell downgraded bonds at fire-sale prices during the 2008–2009 financial crisis.     

Effizienz und Eigentümerstruktur: Eine empirische Analyse des deutschen Lebensversicherungsmarktes

We provide new insights into the effect of ownership on efficiency by analyzing the German life insurance market over the period 2002–2005. Previous research on alternative organizational forms in the life insurance industry has focused on stock and mutual ownership only. Due to the uniqueness of the German insurance market, where privately-owned companies face competition by public insurers, we add to the recent literature the well known debate on public versus private ownership, by investigating stock, mutual and public ownership forms. Using traditional DEA, we calculate technical efficiency and cost efficiency scores to test the efficient structure hypothesis as well as the expense preference hypothesis. Our results give strong support to the latter, while we find no evidence that public ownership is an efficient corporate structure for life insurers. The group of stock firms dominates both, mutual and public insurers, although differences between stock and mutual companies are smaller than differences between stock and public firms. Analyzing within-group results, our findings suggest that high efficiency scores can be associated with certain firm characteristics which are publicly available: high returns on assets, low cancellation rates and low costs.     

The Determinants of Private Debt Holdings: Evidence From the Life Insurance Industry

Life insurers hold the majority of private debt. Lenders in the private debt market must have the ability to evaluate the credit quality of borrowers and to perform ongoing risk monitoring. The purpose of this study is to examine the determinants of private debt holdings in the life insurance industry. The results suggest that larger insurers, insurers with higher financial quality, mutual insurers, publicly traded insurers, insurers facing stringent regulation, and insurers with greater cash holdings are more prevalent lenders in the private debt market.     

Insurers' Demutualization Decisions

ABSTRACT: Several explanations of why mutual insurers choose to demutualize their businesses are examined with a recent survey of mutual insurers. This study adds to the literature by surveying mutual insurers' executives on those factors that would lead them to demutualize their companies. Both univariate and multivariate techniques are applied to analyze those responses. Demutualization is most strongly influenced by access to capital markets, increased organizational flexibility, and the chance for company officers to increase their pay, as prior literature has suggested.     

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.     

CEO Turnover and Ownership Structure: Evidence From the U.S. Property–Liability Insurance Industry

This article examines the impact of ownership structure on the relation between firm performance and chief executive officer (CEO) turnover in the U.S. property–liability insurance industry. Theoretical implications of stock versus mutual ownership structures on the performance–turnover relation are ambiguous. Our empirical results indicate that CEO turnover is less responsive to firm underwriting performance in mutual insurers compared to stock insurers. In fact, we find that while CEO turnover for stock firms is negatively related to prior performance, no such relationship is found for mutual insurers. These results hold while controlling for board structure and other relevant factors.     

Prudent man or agency problem? On the performance of insurance mutual funds

Active equity mutual funds managed by insurance companies underperform peer funds by over 1% per year. There is no evidence that insurance funds make less risky investments; instead they have lower risk-adjusted returns and their fund flows are less sensitive to performance when they perform poorly. Across insurance funds, those with heavy advertising, directly established by insurers or using parent firms' brandnames, and those whose managers simultaneously manage substantial non-mutual-fund assets, are more likely to underperform. We conclude that insurers' efforts to cross-sell mutual funds aggravate agency problems that erode fund performance.     

Cash holdings between public and private insurers ‒ a partial adjustment approach

Cash holdings of financial institutions, especially private firms, have been understudied in existing literature. This paper fills that gap by examining the cash holdings of US property-liability insurers in order to analyze the difference in cash holdings and cash adjustments between public and private stock insurers and between mutual and stock insurers within the private insurer category. We find that public insurers hold much less cash than private stock insurers, which differs from the findings for non-financial firms. Additionally, we find that mutual insurers hold less cash than private stock insurers. Public insurers adjust their cash holdings much faster toward their target cash levels than private stock insurers do when facing an extreme cash shortfall, but their adjustment speed is indifferent from that of private stock insurers when both having excess cash. Mutual insurers are able to adjust cash holdings slightly faster than private stock insurers when there is an extreme cash shortfall but are indifferent in adjustment speed from private stock insurers when having excess cash in hand. Overall, our results are more consistent with the financing frictions hypothesis of cash holdings and are inconsistent with the owner-manager agency problems of free cash flow.

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.     

Determinants of Corporate Diversification: Evidence From the Property–Liability Insurance Industry

This article analyzes variations in line‐of‐business diversification status and extent among property–liability insurers. Our results show that the extent of diversification is not driven by risk pooling considerations; insurers operating in more volatile business lines do not diversify more. Diversification can rather be explained by the benefits of internal capital markets and barriers to business growth like market size and concentration. In our analysis, we distinguish between related and unrelated diversification. Using a measure of unrelated line‐of‐business diversification we find the first support for the diversification prediction of the managerial discretion hypothesis that mutual insurers should be less diversified than stock insurers. While mutual insurers tend to exhibit higher levels of total diversification, they engage in significantly less unrelated diversification than do stock insurers.
