Description: This paper analyzed the deficit risk that an insurer assumes when a group insurance contract is subject to a retrospective experience-rating arrangement. In this paper, a method for quantifying the deficit risk and determining explicitly an appropriate risk charge level is developed.

Description: This paper discusses the purpose and nature of the benefit ratio [otherwise known as active life] reserve in relation to the class of health insurance contracts to which it is intended to apply. From Transactions of Society of Actuaries 1988, Vol. 40, Pt. 1.

Description: This paper discusses the pricing of bond options and interest-sensitive cash flows by discrete state/time models such as binomial lattices. Current binomial models are faulty because the put-call parity relationship may not hold for all periods and there may exist negative interest rates. This paper presents a binomial model without such riskless arbitrage opportunities. This model allows the initial term structure of interest rates to be prescribed exogenously, so that the model price for each stream of fixed and certain cash flows is the market price.

Description: In this paper, methods are presented that allow the systematic graduation of multidimensional data subject to linear constraints. With these constraints the practitioner can impose limitations on the graduation that agree with prior knowledge. Discussions of this paper are included.

Description: The Society of Actuaries Research Institute is pleased to make available a report that aims to understand the cause of low annuity demand through the angle of mortality model uncertainty.

Description: This study summarizes the results of the the Society of Actuaries' Non-Mortality Decrement Task Force data collection effort of plan turnover data for years 1994-2000. Service, by itself, seems not to be a good predictor of retirement. Service and age are each good predictors for termination it is found. The report is designed to offer actuaries information about turnover as it pertains to defined benefit plans.

Description: This paper describes some of the minimum guaranteed death and maturity benefits that have been offered or proposed in conjunction with variable annuity contracts, proposes prospective reserves for these guarantees based on change factors that are somewhat analogous to interest factors used in typical life reserves, and proposes a set of change factors.

Description: This report discusses management decision making practices and the need for actuaries to build the appropriate level of variability for management actions in stochastic models to achieve a more realistic range of future experience among the stochastic scenarios.

Description: This paper examines the effects of selection procedures used in epidemiologic studies and suggests that similar procedures could be employed to select standard ordinary insurance risks at the older ages. The experience in this paper was developed from a prospective epidemiologic investigation launched by the American Cancer Society in the fall of 1959 to learn how personal characteristics, living styles, and environmental conditions influence health and longevity.

Description: The purpose of the present paper is to propose a family of sex-year-of-birth tables which may be used in place of The Annuity Table for 1940 with Projection. From Transactions of Society of Actuaries 1950, Vol. 2, No. 4.
