Description: This paper explores available disability experience data in order to shed some light on the character and extent of the subjective influences which affect the frequency and duration of disability. A mathematical model for computing disability income premiums and reserves is also presented.

Description: This paper considers the distribution of aggregate claims of an insurer. The general form of the distribution is considered initially, and, after a few mild restrictions are imposed, it is characterized as being a compound distribution. Followed by one submitted discussion paper.

Description: This paper presents formulas for the L-Function and shows this function has applications in computing survival rates free from the influence of a given cause of death.

Description: The life annuity mortality risk is the variation in actual financial experience of a group of annuitants from that expected, attributable to the mortality experience of the group. This paper investigated the mortality risk present in a single life annuity and determine the effect of age, sex, assumed interest rate, mortality table, and form of annuity on this risk. Then, it investigated the mortality risk in various portfolios of annuities. Followed by several discussion papers submitted

Description: In this paper a new method of adjusting probabilities of death for short age interval, based on the assumption of a modification in one of the forces of decrement, is developed.

Description: In this paper, the authors created a mathematical model which reflects typical relativities by age, duration of disablement, and deferment period for disability risk. The paper is followed by discussions submitted by various reviewers.

Description: The purpose of this paper is to describe the application of the Monte Carlo technique to a practical situation in a company, group term rate making. It included a discussion of some of the problems encountered and the solution to these problems. Followed by several discussion papers submitted

Description: A presentation of a mathematics/statistics based approach for determining credibility factors for possible use in group health insurance premium rate setting and experience refund setting. Includes supporting mathematical proofs of approach. Followed by discussions submitted by several people

Description: This paper describes risk-factor-dependent multiple decrements and actuarial cost functions as a general compartment model, a discrete time and discrete state stochastic model of morbidity and mortality processes. For large numbers of risk factors, the model is extended to its natural continuous time and state form. From Transactions of Society of Actuaries 1991, Vol. 43.

Description: In this paper, a mathematical model is constructed to study the deviations of claims, investment performance, operating expenses, and lapse expenses as random stochastic processes. Discussions of the paper submitted by 2 readers follows
