Concentration In American Property-Casualty Companies, Edward Nissan

Journal of Actuarial Practice (1993–2006)

A Theil's entropy index utilizing premiums written as units is employed to measure trends in concentration of the largest 200 property-casualty companies in the United States between 1985 and 1993 based on Best's Insurance Report data. Each of the indexes confirms that concentration trends experienced no increase for the whole period for all 200 firms, the top 20, and subsets of lower ranked companies. Significant differences are observed, however, between groups of companies for the same period.

Disclosure And Confidentiality Requirements Of Corporate Pension Plan Actuaries, Theodore Konshak

Journal of Actuarial Practice (1993–2006)

Corporate pension plan actuaries are subject to the standards of the Joint Board for the Enrollment of Actuaries. The Joint Board is empowered to establish such standards under the provisions of the Employee Retirement Income Security Act of 1974, a federal law. In consideration of these statutory standards, this article will discuss whether standards published by professional actuarial organizations have any applicability. The contrast between the disclosure requirements of federal law and the confidentiality standards of the Society of Actuaries will be highlighted.

Methodologies For Determining Reserve Liabilities In The Workers Compensation High Deductible Program, Jerome J. Siewert

Journal of Actuarial Practice (1993–2006)

In this paper I describe several approaches for estimating liabilities under a high deductible program, including a proposal for a more sophisticated approach relying upon a loss distribution model. The discussion addresses several related issues dealing with deductible size and mix, absence of longterm histories, and the determination of consistent loss development factors among deductible limits. In addition, I propose several approaches for estimating aggregate loss limit charges, if any, and the asset value for associated servicing revenue.

Annuity Choices For Pensioners, Zaki M. Khorasanee

Journal of Actuarial Practice (1993–2006)

We consider two ways for a retiree to obtain a pension from a retirement fund: through the purchase of a whole life annuity providing a level monetary income; and through the withdrawal of income from a fund invested in equities. Deterministic and stochastic models are used to assess the risks and benefits associated with each approach. In each case the projected cash flows are compared with those from a whole life annuity providing an income linked to price inflation. We conclude that, although each of the two options conSidered involves significant risks, each method may be attractive to certain groups …

A Possibilistic Linear Programming Method For Asset Allocation, Lijia Guo, Zhen Huang

Journal of Actuarial Practice (1993–2006)

The mean-variance method has been one of the popular methods used by most financial institutions in making the decision of asset allocation since the 1950s. This paper presents an alternative method for asset allocation. Instead of minimizing risk for a given expected return or maximizing expected return for a fixed level of risk, our approach considers simultaneously maximizing the rate of return of portfolio, minimizing the risk of obtaining lower return, and maximizing the possibility of reaching higher return. By using a triangular possibilistic distribution to describe the uncertainty of the return, we introduce a possibilistic linear programming model which …

An Approach To Estimating Market Value And Duration Of Interest-Sensitive Whole Life Contracts, Thomas J. Merfeld

Journal of Actuarial Practice (1993–2006)

A fixed premium interest·sensitive whole life contract is analyzed in order to estimate its market value. In addition, using various definitions of duration, we determine the duration of the contract for each definition. The results of this analysis have implications for market value accounting of life insurance liabilities and for life company portfolio management.

Participating Gics: Performance Attribution Analysis, Alec Stais, John P. Toohey Iii

Journal of Actuarial Practice (1993–2006)

The increasing popularity of participating GICs has created a need for an objective understanding of their performance. The fixed income attribution techniques are not adequate for measuring participating GIC performance because they typically restrict performance measurement to concepts such as duration management, sector rotation, and issue selection. We develop an attribution technique based on four components or effects that are helpful in explaining the changes in credited rates. They are the constant duration effect, the reinvestment effect, the cash flow effect, and the investment effect. The underlying mathematical approach to calculating these effects is presented along with examples.

Bias Of Excluding High And Low Data For Long-Tailed Distributions, Cheng-Sheng Peter Wu

Journal of Actuarial Practice (1993–2006)

Property and casualty actuaries frequently employ a technique of averaging (called high-low averages) that excludes the same amount of data at both ends. For example, (0 in selecting loss development factors, the middle three of the latest five years or the middle eight of latest 12 quarters sometimes are used, or (ii) in calculating average expense ratios, the largest expense ratios and the smallest expense ratios may be removed from the sample. Although highlow averages can reduce the impact of influential data on analyzed results, the averages will result in downward bias when they are applied to pricing or reserving …

Third Party Administrator (Tpa) Service Pricing And Incentive Contracts, Hou-Wen Jeng

Journal of Actuarial Practice (1993–2006)

This paper addresses a few of the most important pricing issues faced by a third party administrator (TPA) whose main responsibility is claims handling for self·insured employers and self·insured groups. Such pricing issues include the development of service fees using claim closure information, the selection of service durations, and the design of incentive (either activity-based or financially-based) service contracts. Formulas for pricing new and open claims are provided.

Nonmedical Limits In Individual Life Insurance, James B. Ross, Shalini E. Perumpral

Journal of Actuarial Practice (1993–2006)

This paper shows data that illustrate the substantial variation among nonmedical schedules and the dramatic increase in their amount limits from 1972 through 1992. Coefficients of variation are analyzed for several data subsets. We find that the variation of schedules in the sample of all firms has increased throughout the 1972-1992 period for issue ages up to 30, but has declined for issue ages beyond 30 during the 1982-1992 period. For the non-New York and stock companies our statistical tests indicate an increase in the variability of schedules over the full period 1972 to 1992.

Pension Funding By Normal Costs Or Amortization Of Unfunded Liabilities, Keith P. Sharp

Journal of Actuarial Practice (1993–2006)

We discuss the extent of the actuary's freedom in choosing the funding method for defined benefit pension plans. In particular, we look at funding through a combination of normal costs, amortization of an unfunded liabilities, and fund of assets. The IRS constraint on "reasonable funding methods" is considered, with particular mention of the aggregate entry age normal method. In addition, an algebraic development is performed of year-to-year changes in the status of a plan's funding.

A Proposal For Improving The System Of Financing Health Care In Singapore, Robert Keng Heong Lian, Loi Soh Loi

Journal of Actuarial Practice (1993–2006)

Like many other countries, including the United States, Singapore faces the dual problems of rising health care costs and an aging population. To cope with these problems, the Singapore government introduced the Medishield scheme in 1989 that provides low cost catastrophic medical insurance coverage. The scheme suffers from a serious deficiency, however: coverage ceases at age 70. This deficiency is exacerbated by Medishield's premium payment structure which is akin to the premium structure of a one year renewable term policy so no reserves are developed. As a result, coverage beyond age 70 requires exorbitant premiums that are beyond the reach …

Cross-Tested Defined Contribution Plans, Ho Kuen Ng

Journal of Actuarial Practice (1993–2006)

Cross-tested plans are defined contribution plans that test allocations for nondiscrimination. The test is based on a plan's actuarial equivalent annuity benefits. Cross-tested plans have become popular among small plan sponsors after the release of the nondiscrimination regulations. This paper investigates the pros and cons of cross-testing.

Discussion Of Ronald T. Kozlowski And Stuart B. Mathewson's "Measuring And Managing Catastrophe Risk", Rade T. Musulin

Journal of Actuarial Practice (1993–2006)

Mr. Kozlowski and Mr. Mathewson's paper provides a good introduction to the development and use of models in the property insurance industry. It will be a valuable addition to the regrettably sparse actuarialliterature in this area. This discussion will offer several comments on the ideas raised in the paper, focusing on how models can be used to enhance an actuary's work. The use of models has sparked major controversies between regulators and insurers in several jurisdictions, notably Florida. Controversy is not limited to the regulatory arena, however. Because models are being used by reinsurers to rate contracts and by A.M. …

Decision Making Under Conflicting Criteria In Pension Valuations: An Expected Utility Model, Lisa Lipowski Posey, Arnold F. Shapiro

Journal of Actuarial Practice (1993–2006)

Many of the criteria used by actuaries when selecting assumptions for pension plan valuations often conflict. As a result, actuaries must weigh the various costs and benefits associated with a particular set of assumptions. We use expected utility theory to model the process of chOOSing actuarial assumptions when faced with potentially conflicting criteria. The three criteria considered are prudence, best estimate, and conservatism. The actual contribution chosen by the actuary is found to depend on the contribution level that triggers a red flag with respect to tax deductibility. If this level is relatively low, the actuary chooses a high contribution …

Sensitivity Testing Of Prdperty/Casualty Cash Flows, Ralph S. Blanchard Iii, Eduardo P. Marchena

Journal of Actuarial Practice (1993–2006)

The paper outlines an approach that has evolved at Aetna through ten years of property/casualty insurance cash flow testing. Methodologies and approaches to setting parameters reflecting both default and call/prepayment risk are discussed for major invested asset categories. Modeling runoff cash flows for a base scenario (and, for some of these assets, shocked scenarios) also is examined for major non-invested asset categories. Loss reserve cash flow modeling is not addressed, except for a brief description of one approach to shocking projected flows. Finally, various alternatives are given for presenting cash flow testing results to management and non-actuarial audiences.

Surveillance Of Life Insurer Solvency: A Comparison Of Stock And The Multiple Scenario Cash Flow Financial Stress Tests, Ronald W. Spahr, Paul L. Gronewoller

Journal of Actuarial Practice (1993–2006)

The solvency of life insurance companies may be threatened by interest rate risk when the maturities of assets and liabilities are mismatched. The National Association of Insurance Commissioners' (NAIC) multiple scenario cashflow test (MSCFT) and the Office of Thrift Supervision (OTS) net portfolio value model (stock) approaches to financial stress tests are illustrated and analyzed with respect to their capacity to estimate the impact of potential changes in interest rates on life insurance company capital and surplus. Each approach is illustrated with the assets and liabilities of three hypothetical life insurance company capital levels (high, average, and below average) and …

Life Insurer Risk-Based Capital: An Option Pricing Approach, Samuel H. Cox, Arthur M.B. Hogan

Journal of Actuarial Practice (1993–2006)

This paper uses an option pricing framework to estimate life insurer risk-based capital. Stock market data and statutory asset and liability data are used to calculate the implied level of statutory risk-based capital for each of 18 insurers. We calculate the level of risk-based capital required to avoid subsidy from the guaranty fund. Our results suggest that less capital is required than that required under the New York actuarial risk-based capital formula. Firm rankings, however, are similar under both methods, although the methods are not directly comparable. We also determine the level of capital required if the subsidy provided to …

Model Year Rating For Automobile Liability And Injury Coverages, Leonard T. Guarini, Edward P. Lotkowski

Journal of Actuarial Practice (1993–2006)

This paper is intended to stimulate further research and discussion on the validity and utility of model year rating for personal automobile coverages other than physical damage. Using data from a single insurer and some elementary statistical techniques, we provide evidence supporting model year as a classification variable for automobile liability and injury coverages.
