Principles And Application Of Credibility Theory, Vincent Goulet

Journal of Actuarial Practice (1993–2006)

We review the history of the practical development of credibility theory. Emphasis is placed on the two main approaches to credibility theory: limited fluctuation credibility and greatest accuracy credibility. We explain when each approach should and should not be used. The presentation of greatest accuracy credibility theory starts with a review of (exact) Bayesian credibility and then moves to the Buhlmann-Straub model. Estimators of the structure parameters are discussed. Examples are presented to illustrate the concepts. Finally, the hierarchical credibility and crossed classification credibility models are presented.

Actuarial Techniques In Risk Pricing And Cash Flow Analysis For U.K. Bank Loans, Philip Booth, Duncan E.P. Walsh

Journal of Actuarial Practice (1993–2006)

A cash flow model is developed to set the price for a loan to a borrower with known risks. Similarities are noted between this model and those used for profit testing in life insurance. We emphasize aspects that reasonably can be treated in several ways and also indicate where the cash flow model differs from the pricing methods usually employed in bank lending. The sensitivity of interest rates to various parameters of the model such as the length of loan and the expected default rate is examined. Also, we examine how features of loans, including cash back and early repayments, …

A Frailty Model For Projection Of Human Mortality Improvements, Shaun S. Wang, Robert L. Brown

Journal of Actuarial Practice (1993–2006)

Based on the everyday observations that individual human beings vary significantly in their capacity to combat death, we adopt a so-called frailty model of human mortality. This frailty model assumes that each individual in a given population is endowed with his or her own frailty index, r, which remains constant for life. In addition, we assume that the individual's force of mortality (hazard rate function) at age x, Ux(r), satisfies Ux(r) = rUx where Ux is the population's base force of mortality at age x. Given the probability distribution of the frailty index among the newborns in the population, an …

Auditor Judgment Confidence: Direct Evidence For The Process View, Marshall A. Geiger, A.C. Lloyd Spurrell

Accounting Faculty Publications

Although there has been considerable research on audit judgment processes and structures, one area that has received little attention is auditor judgment confidence. Determining the nature of confidence attainment has direct implications for audit practice, particularly regarding the timing of evidence evaluation leading to final judgments. The present study extends the early work of Pincus (1991) and is the first to provide direct evidence in support of the process view of audit judgment confidence.

Raising Capital Overseas, John D. Gould, John P. Mcallister, Larry L. Orsini

Faculty Articles

The article states that more and more companies are trying to raise capital by listing their securities for sale on foreign exchanges.More and more companies are trying to raise capital by listing their securities for sale on foreign exchanges. However, the way financial statements are prepared varies from one country to the next. U.S. companies looking to raise capital abroad must consider the myriad rules regarding financial statement presentation just as foreign companies listing stock in the United States must adhere to the rules and regulations of the Securities and Exchange Commission. Similarly, the costs of reconciling U.S. accounting standards …

A New Approach For Determining Claim Expense Reserves In Workers Compensation, Kay Rahardjo

Journal of Actuarial Practice (1993–2006)

This paper describes a new approach for determining a reserve for claim expenses. While the discussion focuses on workers compensation claims, the methodology is equally applicable to other lines of business. The approach also can be applied to the calculation of the reserve for all claims (including IBNR claims) and the reserve for claims reported to date (excluding IBNR claims). In addition, a methodology for pricing claims-handling services is discussed. The implications of pricing claims-handling services on a handle-to- conclusion basis versus pricing claims-handling services on a limited time handling basis are examined. Finally, the paper discusses a methodology for …

Providing Pensions For U.K. Employees With Varied Working Lives, Deborah R. Cooper

Journal of Actuarial Practice (1993–2006)

Several different working lives are investigated, including employees with breaks in employment, part-time employment, and temporary employment. The pensions that could be provided to the different employees by final salary, revalued career average, or money purchase pension schemes (plans) are calculated and compared. Some of the weaknesses in a final salary pension scheme (the treatment of deferred pensioners and cross subsidies between different groups of member) are considered. Possible alternative benefit structures are considered to address the problems.

Seeking The Profitability-Risk-Competitiveness Frontier Using A Genetic Algorithm, Ronnie Tan

Journal of Actuarial Practice (1993–2006)

Monte Carlo simulation is used to develop a flexible framework to measure the profitability, risk, and competitiveness of any insurance product. A genetic algorithm is then used to seek the optimum asset allocations that form the profitability-risk-competitiveness frontier and to examine the profitability, risk, and competitiveness trade-off's. We also show how to select the appropriate asset allocation and crediting strategy in order to position the product at the DeSired location on the profitability-risk-competitiveness spectrum.

Comments On Some Parametric Models For Mortality Tables, Kam C. Yuen

Journal of Actuarial Practice (1993–2006)

Parametric models for the entire age pattern of mortality have been suggested by Heligman and Pollard (1980) and Carriere (1992). The former is designed to fit the classical mortality pattern while the latter is supported by a statistical theory. Insights into their papers motivate us to consider a variation of the Heligman-Pollard model. We also apply these models to the 1993 Hong Kong Assured Lives Mortality Tables as well as the 1991 Hong Kong Female Life Table. This paper is not intended to construct a better parametric model for mortality tables; the main purpose is simply to provide insights into …

Accelerated Death Benefits, Viatical Settlements, And Viatical Loans: Options For The Terminally Iii, Paula Schmidt

Journal of Actuarial Practice (1993–2006)

There are three options available for terminally ill insureds who are interested in accessing all or part of the face value of their life insurance policies: through the life insurance company (accelerated death benefits), through a viatical company (a via tical settlement), or through a via tical loan company (a via tical loan). This paper explores the definitions and tax regulations, calculations, and the claims process associated with accelerated death benefits and via tical settlements and loans.

Pricing Earthquake Exposure Using Modeling, Debra L. Werland, Joseph W. Pitts

Journal of Actuarial Practice (1993–2006)

This paper demonstrates a practical methodology for determining a statewide rate level indication for the earthquake insurance and for determining more equitable territorial relativities within a state. The methodology is based on the output from a certain commercially available earthquake modeling software package. The methodology addresses some of the complex issues involved in pricing earthquake insurance exposure and potential regulatory acceptance. The paper also features a section dealing with the net cost of reinsurance in the proposed direct rates. A final consideration is the treatment of a model's output when it is believed the modeled results art' less than fully …

Dynamic Immunization And Transaction Costs With Different Term Structure Models, Eliseo Navarro, Juan M. Nave

Journal of Actuarial Practice (1993–2006)

A bond portfolio selection model is developed in a dynamic framework using different term structures, but without transactions costs. We show that the optimal portfolios are consistent with Khang's dynamic immunization theorem, i.e., the optimal path consists of making portfolio duration equal to the investor's horizon planning period. The model is then extended to include transaction costs. The resulting optimal portfolios are no longer consistent with Khang's dynamic immunization theorem. In fact, the strategy for constructing the optimal portfolio consists of initially choosing a portfolio with a duration that is smaller than the horizon planning period.

Discussion Of T.A. Moultrie And R.G. Thomas's ''The Right To Underwrite? An Actuarial Perspective With A Difference", Charles L. Trowbridge

Journal of Actuarial Practice (1993–2006)

This interesting but controversial paper studies a subject I too have seriously considered. Nearly a decade ago I was commissioned to prepare a monograph that appeared in 1989 under the auspices of the Actuarial Education and Research Fund under the title Fundamental Concepts of Actuarial Science. 1 Chapter VII of this work, "Classification, Selection, and Antiselection," claims that the cluster of ideas surrounding these three words form a fundamental actuarial concept. I have recently reviewed this monograph (hereinafter FCAS) and am struck by the dissimilarities between the two treatments. The authors of "The Right to Underwrite?" (RTU) were unaware of …

Fuzzy Underwriting: An Application Of Fuzzy Logic To Medical Underwriting, Per-Johan Horgby, Ralf Lohse, Nicola-Alexander Sittaro

Journal of Actuarial Practice (1993–2006)

One of the most difficult issues in the medical underwriting of life insurance applicants is diabetes mellitus. Compiling the prognosticating parameters for diabetic applicants results in a complex system of mutually interacting factors. In addition, neither the prognosticating factors themselves nor their impact on the mortality risk is clear cut. We show how a fuzzy inference system can be used in underwriting diabetes mellitus. A fuzzy inference system can cope with the imprecise nature of medical parameters by converting them into fuzzy sets and aggregating them using mathematical techniques. The fuzzy underwriting system presented goes further than previous applications of …

The Right To Underwrite? An Actuarial Perspective With A Difference, Thomas A. Moultrie, Guy R. Thomas

Journal of Actuarial Practice (1993–2006)

For a long time underwriting has been a part of the actuarial canon. With increasing frequency, however, challenges are being issued against the right of insurance companies to underwrite applications for new bUSiness, arguing that certain aspects of the practice are undesirably discriminatory. We explore the role of the actuary in the underwriting process and the challenges that are being set for the profession (as opposed to the life insurance industry) as a result of this role. As the distinction between the interests of the actuarial profession and the interests of the life insurance companies has become increasingly blurred, we …

Actuarial Model Assumptions For Australian Inflation, Equity Returns, And Interest Rates, Michael Sherris

Journal of Actuarial Practice (1993–2006)

Though actuaries have developed several types of stochastic investment models for inflation, stock market returns, and interest rates, there are two commonly used in practice: autoregressive time series models with normally distributed errors, and autoregressive conditional heteroscedasticity (ARCH) models. ARCH models are particularly suited when there is heteroscedasticity in inflation and interest rate series. In such cases nonnormal residuals are found in the empirical data. This paper examines whether Australian univariate inflation and interest rate data are consistent with autoregressive time series and ARCH model assumptions.

Finance: A Management Guide For Managing Company Funds And Profits By M Pandey. Prentice-Hall Of India, 1995., V G Sridharan

IIMB Management Review

This book throws light on all the three well-established segments of finance: accounting, costing and funds management, especially for those business executives uninitiated in its basic tenets. Starting with the primary appreciation of the contents of financial statements, it introduces the reader to the techniques of comparative analysis of such statements, like accounting ratios and fund flows.

Asset Allocation In Investing To Meet Liabilities, Anthony Dardis, Vinh Loi Huynh

Journal of Actuarial Practice (1993–2006)

We present some rudimentary concepts on asset/liability management and describe an approach to asset allocation modeling for institutions that invest to meet liabilities. The traditional risk/reward framework of financial economics is used as a starting pOint. The definitions of risk and reward are then refined with regard to the institution under consideration. A simple model of a U.S. life office is examined. We assume that the only investments available are domestic stocks and long-dated government bonds. Stochastic simulation is used to create a large number of future investment scenarios using historical total return data for these asset classes. The ability …

Constrained Forecasting Of The Number Of Ibnr Claims, Louis G. Doray

Journal of Actuarial Practice (1993–2006)

We consider the problem of forecasting the number of claims incurred. After subtracting the number of claims reported to date, the number of claims incurred but not reported (IBNR) can be forecasted. The basic model assumes that the number of claims per accident period follows an autoregressive moving average time series process. Instead of assuming the data are available in the usual claim run-off triangle format, we assume that the only data available are the number of claims reported at the valuation date for each accident interval of an observation period. Box-Jenkins methods are used to forecast the ultimate number …

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.

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.
