Improving Mortality: A Rule Of Thumb And Regulatory Tool, John H. Pollard

Journal of Actuarial Practice (1993–2006)

We develop a simple exact formula for determining cohort life expectancies under constant continuous uniform improvement in mortality using only a cross-sectional (period) Gompertz life table for the lives concerned and a simple approximation applicable to all life tables. The present values of annuities for such lives can be determined simply and accurately across the whole age span.

Modeling Size-Of-Loss Distributions For Exact Data In Winbugs, David P.M. Scollnik

Journal of Actuarial Practice (1993–2006)

This paper discusses how the statistical software WinBUGS can be used to implement a Bayesian analysis of several popular severity models applied to exact size-of-Ioss data. The particular models targeted are the gamma, inverse gamma, loggamma, lognormal, (two-parameter) Pareto, inverse (two-parameter) Pareto, Weibull, and inverse Weibull distributions. It is possible to implement additional size-of-Ioss models (including those for truncated data) using methods analogous to those described herein.

Model Risks And Surplus Management Under A Stochastic Interest Rate Process, Jennifer L. Wang, Rachel J. Huang

Journal of Actuarial Practice (1993–2006)

This paper uses simulations to explore the effects of incorrectly identifying the underlying interest rate process on assets, liabilities, and surplus levels. We show that mismodeling the interest rate (called model risk) could not only lead to a misstatement of the company's surplus, but could also cause a mismatch between the company's assets and liabilities. Our simulations demonstrate that three aspects of interest rates affect model risk: (i) volatility, (ii) level of long-term interest rate, and (iii) the speed at which the drift rate adjusts. We conclude that asset-liability managers should not ignore the impact of the model risks, regardless …

Unearned Premiums And Deferred Policy Acquisition Expenses In Automobile Extended Warranty Insurance, Joseph Cheng

Journal of Actuarial Practice (1993–2006)

A prorata formula is commonly used to calculate unearned premium reserves in property-casualty insurance. I believe, however, that an exposure-adjusted formula is more appropriate in automobile extended warranties. This paper describes the exposure-adjusted approach to calculate the unearned premium reserves of an automobile extended warranty insurance program, to test the adequacy of the calculated reserves, and to determine the allowable deferred policy acquisition expenses from an insurance company's perspective.

Can Utility-Maximization Models Assist With Retirement Planning?, Zaki Khorasanee

Journal of Actuarial Practice (1993–2006)

Utility-maximization models for optimizing portfolio choices can be subdivided into two classes: those based on maximizing the expected utility of lifetime consumption and those based on maximizing the expected utility of retirement wealth. It is argued that the first type of model, which optimizes both saving and investment decisions, is difficult to apply in practice because of inadequate (or unreliable) information about individual preferences. Although the second type of model only optimizes investment decisions, it is of greater practical value because fewer data on individual preferences are required. The second type of model is used to derive formulae for the …

Some Comments On The Pricing Of An Exotic Excess Of Loss Treaty, Jean-Francois Walhin

Journal of Actuarial Practice (1993–2006)

This paper uses a multivariate analog of Panjer's algorithm to develop a method for pricing a complex excess of loss treaty. The treaty is such that some layers inure to the benefit of other layers. The structure of this treaty is discussed. Numerical examples are provided.

Communicating Effectively With Words, Numbers, And Pictures: Drawing On Experience, Karolina Duklan, Michael A. Martin

Journal of Actuarial Practice (1993–2006)

In this paper, we discuss techniques for developing effective communication skills, focusing in particular on technical writing, the use of graphics, and presentation. The key principles of effective communication that we propose to actuaries are as follows:

• Identify your audience and consider their needs and abilities;

• Focus on substantive content;

• Choose appropriate communication tools;

• Use language that is simple, concrete, and familiar;

• Integrate text, numbers, and graphics;

• Respond to information complexity creatively.

We focus in particular on the use of graphics as a communications tool as they are an efficient and potentially highly effective …

Further Remarks On Risk Sources Measuring: The Case Of A Life Annuity Portfolio, Mariarosaria Coppola, Emilia Di Lorenzo, Marilena Sibillo

Journal of Actuarial Practice (1993–2006)

The paper considers a model that allows the actuary to measure the riskiness connected to the randomness of projected mortality tables in evaluating a portfolio of life annuities, obtaining a measure to reflect the risk associated with the randomness of the projection. The coherence of the risk parameters with the specific nature of the considered risk sources is also discussed. Numerical examples illustrate the results, showing the importance of the risk components in terms of the number of policies and comparing measure tools obtained by means of two procedures.

A Note On The Parallelogram Method For Computing The On-Level Premium, David P.M. Scollnik, Wai Man Sara Lau

Journal of Actuarial Practice (1993–2006)

This paper discusses the differences appearing in the descriptions of the parallelogram method for the determination of earned premium at current rate levels given by McClenahan (1996) and Brown and Gottlieb (2001). It observes that the former is consistent with the method of extending exposures while the latter is not. An illustration is provided. This paper also discusses two other approaches to the determination of the earned premium.

Dynamic Funding And Investment Strategy For Defined Benefit Pension Schemes: A Model Incorporating Asset-Liability Matching Criteria, Shih-Chieh Chang, Cheng-Hsien Tsai, Chia-Jung Tien, Chang-Ye Tu

Journal of Actuarial Practice (1993–2006)

This paper studies the dynamic funding policy and investment strategy for defined benefit pension plans using one of the most comprehensive dynamic pension models to date. The model includes three investable assets: one risk free and two risky. The optimal plan decisions are formulated as a stochastic control problem that is solved using dynamic programming. The objective function uses performance measures to take into account the stability and solvency of the plan. The model is then applied to a Taiwanese pension.

An Empirical Investigation Of The Relationship Between Audit Committee Effectiveness And Internal Auditors' Professional Objectivity, Sarjo Jah

Student Works (2000-2009)

The objective of this study is to empirically investigate the relationship between audit committees effectiveness and internal auditors' professional objectivity. The study attempts to determine whether or not audit committees effectiveness enhances the professional objectivity and independence of internal auditors. A mail questionnaire, which was used to collect data, was sent to internal auditors as well as audit committee chairmen. The data collected had been analysed using a parametric t-test. The findings of the study showed that there is a positive relationship between audit committee effectiveness and internal auditors professional objectivity. This study adds to existing local literature on audit …

Off-Shore Borrowing And Guarantees By Banks: Implication For Portfolio Management., C. C. Edordu

Bullion

The subject I have been asked to reflect on is important and somewhat provocative given the potential significance of foreign capital in the development process and the implied doubt the topic raises about the capacity of banks to manage their portfolios on accessing external finance. With regard to financing tenors, it is pertinent to point out that the tenor of liabilities of most banks in Nigeria and Africa is short. The paper has focused on the various discussions about the conditions for good governance, which raises questions about the structure and functioning of the state, its relationship to society and …

Fitting Loss Distributions In The Presence Of Rating Variables, Farrokh Guiahi

Journal of Actuarial Practice (1993–2006)

This paper focuses on issues and methodologies for fitting alternative statistical models-parametric probability distributions-to samples of insurance loss data. The interactions of loss distributions, deductibles, policy limits, and rating variables in the context of fitting distributions to losses are discussed. Fitted loss distributions serve an important function in pricing insurance products. The methodology developed in this paper is applied to a sample of insurance loss data that has the lognormal as the underlying loss distribution.

Linear Empirical Bayes Estimation Of Survival Probabilities With Partial Data, Mostafa Mashayekhi

Journal of Actuarial Practice (1993–2006)

In this paper we consider linear empirical Bayes estimation of survival probabilities with partial data from right-censored and possibly left-truncated observations. Such data are produced by studies in which the exact times of death are not recorded and the length of time that each subject may be under observation cannot exceed one unit of time. We obtain asymptotically optimal linear empirical Bayes estimators, with respect to the squared error loss function, under the assumption that the probability of death under observation in a unit time interval is proportional to the length of observation. This assumption is sometimes implied by Balducci's …

A Sensitivity Analysis Of The Premiums For A Permanent Health Insurance (Phi) Model, Ben D. Rickayzen

Journal of Actuarial Practice (1993–2006)

This paper presents an analysis of the parameters used in a multi-state model for permanent health insurance (PHI). The model is a simplification of that used in the United Kingdom. To avoid using duration dependent probabilities, the model splits the sick state into several sub-states to act as a proxy for duration spent in a particular state. This enables a Markov approach to be adopted. Lapses are incorporated within the model, and the net premium for a particular policy is tested for sensitivity to the various parameters used, including their interaction with the lapse rate. One of our conclusions is …

Controlling The Solvency Interaction Among A Group Of Insurance Companies, Alexandros Zimbidis, Steven Haberman

Journal of Actuarial Practice (1993–2006)

Pooling of risks is an efficient risk management technique used by large employee benefit schemes of multinational companies to self-insure their retirement and other benefit obligations. This technique forms a basis for formulating a general control theoretic model for the interaction between insurance companies within a pooling network. The objective of these insurance companies is to avoid insolvency yet maintain stable premium and surplus processes. A general control system of equations that is used as a model for the interaction of m insurance companies within the network is first analyzed. An analytic solution is provided. Questions concerning the stability and …

Exponential Bonus-Malus Systems Integrating A Priori Risk Classification, Llufs Bermudez, Michel Denuit, Jan Dhaene

Journal of Actuarial Practice (1993–2006)

This paper examines an integrated ratemaking scheme including a priori risk classification and a posteriori experience rating. In order to avoid the high penalties implied by the quadratic loss function, the symmetry between the overcharges and the undercharges is broken by introducing parametric loss functions of exponential type.

Premium Earning Patterns For Multi-Year Policies With Aggregate Deductibles, Thomas Struppeck

Journal of Actuarial Practice (1993–2006)

MUlti-year policies with large aggregate deductibles or multiple triggers raise some interesting issues about the correct amount of unearned premium reserve that a company should carry. Examples in this paper illustrate some of the difficulties that arise when trying to establish such reserves. The basic approach taken here is that the pure premium portion of the unearned premium reserve should always be adequate to cover the remaining risk. This approach, however, can lead to some unusual and controversial earning patterns; there are even situations where a negative premium is earned. In addition, the earning pattern for a particular loss scenario …

Analyzing Management Fees Of Pension Funds: A Case Study Of Mexico, Tapen Sinha

Journal of Actuarial Practice (1993–2006)

Though the rates of return for public pension funds have been high over the past two decades, one critical aspect of the financing of this type of fund is often overlooked: high management fees. As a result, the rates of return for workers who have invested in these funds have not necessarily been high. Management fees charged on pension funds in Mexico result in a leakage of funds in the order of 20-30% of the fund. That is, the amount at retirement would have been 20-30% higher had there been no fees. A model is developed that includes all the …
