Description: Series of letters discussing the controversial Gershenson formula for calculating exposures for mortality tables at the end of the observation period.

Description: Without relying on formulas, this paper presents the important concepts underlying the theory of arbitrage-free pricing of interest-rate-contingent cash flows: absence of opportunities for riskless arbitrage, completeness of markets, relative prices that do not depend on individual investors' subjective views or risk preferences, and expected-value pricing in the risk-neutral world. Using these concepts, the paper then describes the steps required to build continuous stochastic models of interest rates, including models that are either partially or fully arbitrage free.

Description: This report compares health care utilization and expenditures between individuals with Crohn’s disease who had used infliximab and those who had not. Claims data from the 1999-2003 Thomson Reuters MarketScan commercial claims and encounters databases and inpatient, outpatient, and prescription drug claims data of individuals older than 18 years of age with a diagnosis of Crohn’s were included.

Description: An extension of a paper published in the 1952 Transactions by the same author, describing and classifying various funding methods for defined benefit pension plans. Followed by discussion papers submitted by several authors.

Description: In this paper a model of term insurance experience is constructed on the basis of mortality classes theory and utility theory. The model generates a complete set of mortality, withdrawal, and conversion rates on term insurance and of mortality rates on converted policies . The resulting decrement rates can be used in a Jenkins-type formula to calculate gross premiums.

Description: This paper discusses an example showing how simulation has been used to develop financial projections for variable life insurance with a guaranteed minimum death benefit and how recourse to mathematical analysis based on risk-theoretic considerations can enable us to see the impact of stock price changes more clearly. These projections reveal the effects of stock price fluctuations interacting with the more common elements, such as mortality and persistency, on the financial results of a variable life insurance operation.

Description: The purpose of this study is to provide the actuarial profession with a review of the actuarial aspects of cash balance retirement plans and original actuarial research regarding the design and valuation of such plans. This report discusses cash balance plan features and methods to measure the associated risks.

Description: A new approach to computing annual pension costs, based on an open-group projection of the participant population for a number of years, was described in detail in a paper published in the 1975 Transactions, entitled 'The Forecast Valuation Method for Pension Plans.' That paper described the operation of such a cost method at the initial valuation date. This paper discusses several alternative approaches to projection valuation methods and also describes how costs should be computed at valuation dates after the first one. In addition, the author illustrates projected contributions and asset buildups under both traditional [closed-group] cost methods and projected [open-group] cost methods, for a number of years under a variety of assumptions as to the growth rate of the participant group. Projection valuation methods have not been described heretofore in sufficient detail to make it possible for actuaries to use them on a recurring basis or for the Internal Revenue Service to make a determination as to the acceptability of such approaches for computing tax-deductible pension plan contributions. It is the hope of the author that this paper will fill both of those gaps. From Transactions of Society of Actuaries 1977, Vol. 29.

Description: This paper indicates the historical development of equity-based insurance products in the United Kingdom, describes the types of equity-based life insurance products now being sold, presents the actuarial bases underlying these products including the treatment of asset value guarantees, and considers the application of United Kingdom product concepts in the United States and Canadian environment.

Description: Public Law 93-445 provided for a complete restructuring of the railroad retirement system. This paper discusses 2 of the issues/problems underlying the need for the restructuring. These were 1 concurrent social security benefits paid to railroad annuitants 2 the approach used to increase benefits to keep up with inflation. Also a discussion of the basic achievement of the new law, which was to create a two-tiered benefit structure. Followed by 2 discussion papers submitted
