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: This paper by the SOA Committee on HIV research builds on past work to show three projections of the future of the AIDS epidemic. These scenarios can provide information to actuaries in considering the financial impact of AIDS for life and health insurance. The paper develops general population AIDS mortality rates related to the three scenarios. From Transactions of Society of Actuaries 1990, Vol. 42.

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: This is the second report of the study of claim frequencies, charges, and claim costs for a sample of basic Group Hospital and Surgical Expense insurance plans. This report combines data with respect to experience during 1967, 1968, and 1969. From Transactions of Society of Actuaries 1971 Reports

Description: The Joint Committee on Health Insurance appointed a subcommittee, known as Task Force 4, to study the problems of reserves for accident and health insurance. The final report of the Task Force, including basic tables of net annual claim costs for hospital and surgical expense insurance, was adopted by the NAIC at its December 1956 meeting. This article contains the Task Force's final report [included as Appendix A] and 30 Tables for use in valuing hospital and surgical expense insurance in accordance with the recommendations of Task Force 4. From Transactions of Society of Actuaries 1957, Vol. 9, No. 25.

Description: This paper presents an analysis of group weekly indemnity continuation table data contributed by seven companies. Claims costs and other data are developed for this short term disability type coverage.
