A Comparative Study Of The Performance Of Loss Reserving Methods Through Simulation, Prakash Narayan, Thomas Warthen

Journal of Actuarial Practice (1993–2006)

Actuaries are often asked to provide a range or confidence level for the loss reserve along with a point estimate. Traditional methods of loss reserving do not provide an estimate of the variance of the estimated reserve, and actuaries use various ad hoc methods to derive a range for the indicated reserve. We use a Monte Carlo simulation method to compare various loss reserve estimation methods, including traditional methods and regression-based methods of loss reserving.

Safe-Side Requirements In Life Insurance: A Corporate Perspective, Annamaria Olivieri, Ermanno Pitacco

Journal of Actuarial Practice (1993–2006)

Safe-side requirements concern the assumptions used to calculate premiums in relation to a set of more realistic assumptions. Roughly, safe-side requirements express the capability of premiums to generate positive margins. In a strictly actuarial framework, safe-side requirements are given in terms of some notion of expected profit, calling for assumptions that let such profit be non-negative. An expected profit of zero, however, is not a realistic aim for the insurer. We investigate the notion of conservative assumptions by adopting a unconventional approach. Our focus is the management of the financial resources coming both from premiums and from shareholders' capital. This …

Realistic Pension Funding: A Stochastic Approach, Shih-Chieh Chang

Journal of Actuarial Practice (1993–2006)

The process funding pension plans is viewed as a dynamic control process. Two performance measures are introduced to evaluate the effectiveness of plan contributions: the cost-induced performance measure (CIPM) and the ratio-induced performance measure (RIPM). A dynamic programming approach is used to determining the optimal contributions with the objective of minimizing the performance measure. The methodology developed is applied to a sample of members of Taiwan's Public Employees Pension Plan (Tai-PERS). We show that RIPM produces more stable results than those using CIPM.

This report is divided into five chapters. Chapter 1 discusses the fundamental principles and mode of operations of both conventional and Islamic banks. Chapter 2 reviews the literature pertaining to the performance of Islamic banks in …

Relationship Between Risks And Return In The Kuala Lumpur Stock Exchange, Keat Chye Khoo

Student Works (2000-2009)

Results of empirical tests on the relationship between stock returns and arious risk factors of sixty stocks in the Kuala Lumpur Stock Exchange over the eriod 1979-1998 are presented in this study. Overall the applicability of the capital sset pricing model in Kuala Lumpur Stock Exchange using monthly data is absent. 1arket risk alone or with another risk factors are unable to explain the variation in verage returns. However, there is a significant non-linear relationship between verage returns of individual stocks and market risk in two test periods 1983-86 and 995-98. This study also finds that other risk factors are …

Seasonality Effects Of Finance Stocks On The Kuala Lumpur Exchange, Foon Lee Ng

Student Works (2000-2009)

The primary objective of this study is to investigate the seasonality effect or calendar anomalies of Finance stocks on the Kuala Lumpur Stock Exchange (KLSE) over the period of January 1992 to June 1999. Among the calendar anomalies investigated in this study are the day-of-the-week effect, the pre-holiday effect, the end-of-the-month effect and the firm size effect. Empirical results reveal that there is an existence of the day-of-the-week effect in the financial stocks for the entire sample period. The results are consistent with those previous studies in which Monday's returns are significantly negative whilst Friday's returns are positive. In particular, …

A Study Of Stock Market Efficiency In Malaysia, Shook Chern Lee

Student Works (2000-2009)

This study examines the behaviour of the stock market in Malaysia and its implication on the weak form efficiency of the Efficient Market Hypothesis. Daily data of the number of stocks advancing, declining or remaining unchanged in price and the closing levels of the stock market indices of the Main Board, seven main sectors of the Main Board and the Second Board of the KLSE were used in this study. The period covered was from January 1994 to December 1998, a total of 1233 trading days. The results using the Theil-Leenders test indicates that there is some dependence in successive …

Independent Claim Report Lags And Bias In Forecasts Using Age-To-Age Factor Methodology, Stewart Gleason

Journal of Actuarial Practice (1993–2006)

This paper finds that when report lags are assumed to be independent, the age-to-age factor method produces biased estimates when applied to claim count development data. Two distributions are considered as models for the ultimate number of claims for an accident period: (0 a Poisson distribution, and (ii) a negative binomial distribution. In the Poisson case, the assumption of independent report lags implies the independence of the total number of claims reported in any two periods. In the negative binomial case, however, assuming that report lags are independent does not imply that increments are independent, and a somewhat different argument …

Actuarial Analysis Of Retirement Income Replacement Ratios, Robert Keng Heong Lian, Emiliano A. Valdez, Chan Kee Low

Journal of Actuarial Practice (1993–2006)

A measure of level of post-retirement standard of living is the replacement ratio, i.e., percentage of final salary received as annual retirement income derived from savings. The replacement ratio depends on many factors including salary, salary increases, investment returns, and post-retirement mortality. Elementary life contingencies techniques are used to develop a replacement ratio formula and analyze its sensitivity to these factors.

A Study Note On The Actuarial Evaluation Of Premium Liabilities, Claudette Cantin, Philippe Trahan

Journal of Actuarial Practice (1993–2006)

Several approaches have been used to estimate premium liabilities. The emphasis of these approaches has been on unearned premium and deferred policy acquisition expenses (DPAE), as such items represent the largest components of premium liabilities. The purpose of this paper is to provide a framework for the evaluation of premium liabilities and to augment the actuarial literature. We define and review the individual components of premium liabilities as well as the regulatory requirements and Canadian Institute of Actuaries recommendations and standards of practices related to premium liabilities. We also present an actuarial approach for estimating equity in the unearned premium, …

Commissioners Annuity Reserve Valuation Method (Carvm), Keith P. Sharp

Journal of Actuarial Practice (1993–2006)

This paper describes the commissioners annuity reserve valuation method (CARVM) and highlights the fundamental contrast with insurance valuation. Numerical examples illustrate methods of applying CARVM to particular annuity designs. The application of NAIC Actuarial Guideline 13 on bailouts is given particular attention.

Determination Of Optimal Premiums As A Constrained Optimization Problem, Farrokh Guiahi

Journal of Actuarial Practice (1993–2006)

A simple stochastic model of an insurer's underwriting and related investment operations is used to determine the optimal amounts of written premiums for one period for the insurer's book of business. The written premium for each class is determined by the solution of a constrained optimization problem. The insurer's objective function is the expected profit on a book of business over the period. The insurer has a safety constraint where a certain portion of capital and surplus can be depleted with a small probability. This paper provides an explicit solution for optimum expected profit and corresponding written premiums by classes. …

A Fuzzy Approach To Grouping By Policyholder Age In General Insurance, Richard J. Verrall, Yakoub H. Yakoubov

Journal of Actuarial Practice (1993–2006)

In general insurance, policyholder age is often treated as a factor with the number of levels requiring that the individual ages of the policyholders be grouped. Although the groups are usually defined by the existing underwriting structure, it should be investigated as part of any premium rating exercise that uses a model to assess past claims experience. It is possible that an incorrect grouping by policyholder age could bias the results of the risk premium estimation. On the other hand, it may not be computationally feasible to use separate ages in the premium model, making some form of grouping necessary. …

Multilife Premium Calculation With Dependent Future Lifetimes, Michel Denuit, Anne Cornet

Journal of Actuarial Practice (1993–2006)

Actuaries traditionally have calculated multi-life (joint life) premiums by assuming the independence of the future lifetimes of insured persons. Recent studies, however, demonstrate dependence of the future lifetimes of couples (such as husbands and wives). This dependence materially affects the values of multi-life annuities and insurances. Using the Frechet-Hoeffding bounds and Norberg's Markov model, we determine the effect of this dependence in lifetimes on the actuarial present values of a widow's pension benefit.

Recognizing Actuarial Assumptions, Victoria Stachowski, Alice Underwood

Journal of Actuarial Practice (1993–2006)

As assumptions underlie every aspect of actuarial calculations, actuaries must be aware of the assumptions they are using and understand their importance and the possible effects of changing assumptions on the results of their calculations. This paper explores the nature of assumptions in: (i) mathematical models, (ii) data selection, (iii) actuarial methods, and (iv) the business environment. We examine reasons for making assumptions such as convenience, tradition, indications in the data, or lack of data. In addition, we discuss (i) how actuaries can judge whether these reasons are sufficient; (ii) methods that can help actuaries quantify the impact of their …

Carvm And Naic Actuarial Guidelines 33 & 34, Keith P. Sharp

Journal of Actuarial Practice (1993–2006)

Annuity valuation under the NAIC Standard Valuation Law is determined according to methods different from those methods used for life insurance. The CARVM assumption of efficient policyholder selection is clarified under NAIC Actuarial Guidelines 33 and 34 to allow for non-elective (e.g., death) benefits. In particular, Actuarial Guideline 34 is oriented toward variable annuities and prescribes methods to be used in the presence of a minimum guaranteed death benefit. In this paper these methods are examined and illustrated with examples.

Credibility Calculations Using Analysis Of Variance Computer Routines, Dennis H. Tolley, Michael D. Nielsen, Robert Bachler

Journal of Actuarial Practice (1993–2006)

In this paper we present a method of calculating Buhlmann-Straub credibility factors using standard statistical techniques developed for the analysis of variance. Emphasis is placed on using readily available statistical packages such as SAS and SPSS. Additionally many other computational tools such as EXCEL can be programmed to make such calculations. An example and some sample SAS programs are provided.

Towards Relevancy In Financial Reporting: Mark-To-Market Accounting, Eunsup Daniel Shim, Joseph M. Larkin

WCBT Faculty Publications

The objectives of this paper are to: discuss the relevancy vs. reliability of current financial reporting practices, survey the literature that describes the impact of mark-to-market accounting, critically examine current GAAP financial statements by comparing them to market value financial statements. With theoretical discussions and a case study, this paper shows that the mark-to-market accounting could present better about the economic reality of transactions and, therefore, tends to provide more useful and relevant information than does historical cost financial reporting. This study suggests that if the objective of financial reporting is to provide "useful" information to the users, existing GAAP …

Qualitative Materiality In Government Audit Planning, Sridhar Ramamoorti, Andrea Lee Hoey

Accounting Faculty Publications

The political sensitivity of the area under audit to adverse media exposure and litigation concerns the nature rather than the size of an amount, such as illegal acts, bribery and corruption, related party transactions, snowballing patterns of error and other risks that grow over time. Qualitative materiality considerations should not be ignored-they can and frequently do influence the nature and scope of governmental audits. Financial Accounting Standards Board Concepts Statement No. 2 defines materiality as the magnitude of an omission or misstatement that would influence the decisions of a user of financial statements. Audit planning needs to incorporate considerations of …

Using Parametric Statistical Models To Estimate Mortality Structure: The Case Of Taiwan, Shih-Chieh Chang

Journal of Actuarial Practice (1993–2006)

A mixture parametric model is used to analyze the changing pattern of Taiwanese mortality from 1926 to 1991. Three different age ranges are modeled as mixtures of extreme value distributions, namely the Weibull, inverse Weibull, and Gompertz distributions. The results show a significant improvement of mortality over the years.

Outlier Analysis Of Annual Retail Price Inflation: A Cross-Country Study, Wai-Sum Chan

Journal of Actuarial Practice (1993–2006)

Wilkie's stochastic investment model and its variants have been increasingly applied by actuaries around the world to actuarial modeling and simulation. This paper performs time series outlier analysis on retail price inflation, which is the driving force of Wilkie's composite model. The data come from four developed countries: the United Kingdom, the United States, Canada, and Australia. The fit of the model is significantly improved after the adjustment of outliers. The analysis also identifies exogenous events that have intervened in the inflation dynamics. An example is given to demonstrate the importance of outlier analysis on stochastic simulation. Finally, inflation trends …

Stability Of Representative Crediting Rate Scenarios Under Monte Carlo Simulations, Sarah L.M. Christiansen, Kelley Buchacker

Journal of Actuarial Practice (1993–2006)

We develop a methodology to ensure that a Monte Carlo simulation of the distribution of the primary rates, used for determining an interest crediting rate, is stable regardless of the initial random number seed. We consider the implications of the use of antithetic random normal deviates upon the scenario process and modifications to the candidate list and the choice function within the representative process. It is shown that the use of antithetic random deviates alone does not have a statistically significant effect on our results. The other two modifications (candidate selection algorithm and choice function) are statistically significant. Furthermore, the …

An Analysis Of Australian Pensioner Mortality By Pre-Retirement Income, David Knox, Andrew Tomlin

Journal of Actuarial Practice (1993–2006)

The existence of a relationship between an individual's socioeconomic status and his or her mortality is often accepted, but it is difficult to measure this relationship objectively. This study analyses the relationship between an individual's final salary immediately prior to retirement and mortality rates during retirement. The data used are taken from a large Australian public sector pension plan. A strong inverse relationship is found, which decreases with age. Some of the implications of these results for individual annuity markets and public pension policy are discussed.

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, …
