Description: This paper, part of the Society of Actuaries [SOA} ‘Research Projects – Finance/Investment,’ presented by the SOA’s Committee on Finance Research, describes the results of a survey of industry practices on the mechanics and implementation of hedging programs used by life insurance companies to minimize risk for product guarantees on variable annuities.

Description: The purpose of this paper is to provide a unified theory for the evaluation of underwriting requirements where this evaluation is based on the measurement of the levels of mortality costs associated with such requirements. A discussion of this paper is included.

Description: In this paper, a general multivariate duration analysis is introduced that does not depend on a mathematical formulation of the way in which a yield curve moves. A discussion of the paper follows. From Transactions of Society of Actuaries 1991, Vol. 43.

Description: With this paper, a new theory of immunization is introduced in which the approach is multivariate, and the goal is stochastic in the sense of minimizing stochastic risk. Discussions of this paper are included.

Description: This paper presents a new insight into the mathematical structure of asset share-type calculations. Asset shares are interpreted as accumulations of insurance cash flows, which along with their related investment income, are treated as Stieltjes integrals. From Transactions of Society of Actuaries 1978, Vol. 30.

Description: The goal of this paper is to develop best possible estimates for the higher moments of a distribution of a positive bounded random variable, such as claim amounts, where these estimates are given in terms of the mean.

Description: In this paper, the relationship of convexity to the assumption of parallel shifts is explored, and new convexity measures are developed to reflect nonparallel shifts. These new measures can differ dramatically from the traditional values, providing insight into when convexity does not have to be good and when it does.

Description: This paper discusses extending the general nonparallel shift approach to duration analysis developed previously and explores the immunization model within the multivariate context. A discussion of the paper follows. From Transactions of Society of Actuaries 1991, Vol. 43.

Description: The author previously wrote about extending the general nonparallel shlft approach to duration analysis. This paper explores the immunization properties of that model. In addition, applications to asset-liability management are explored. From Actuarial Research Clearing House 1990 VOL. 2.
