Description: In an increasing population the number of persons falls off from age to age more rapidly than does the stationary population of the life table. This can introduce a systematic bias into life table calculations. The first part of the paper describes an iterative procedure to correct for the bias, extends the method to multiple decrement and associated single decrement life tables, and demonstrates the magnitude of the bias involved. The second part of the paper summarizes the results of applying iterative life table techniques to 165 populations which encompass over a century's experience and include countries from all parts of the world.

Description: This paper presents mortality rates by sex at ages 90 and above for persons who received retired worker benefits from the social security program for the first month that such benefits were paid. Followed by a discussion paper

Description: This is the digest from the informal discussion reviewing the 1951 Impairment study. It is the latest in a series of studies covering mortality of impaired risks. It covers the experience under Ordinary insurance issued from 1935 to 1949 traced to the anniversaries in 1950. Standard and substandard policies were studied separately.

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: The actuarial profession is faced with a problem of determining delta-ized reserves on a basis which will include appropriate provision for adverse deviations in mortality, lapses, interest rates, and expense rates. This paper describes briefly a method which could be used to solve this Followed by papers submitted by 2 authors problem in a flexible manner.

Description: This paper develops a new method of determining long-range interest rate assumptions. Followed by discussion papers submitted by 2 authors

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: This paper illustrates a procedure for analyzing the sources of profit under FAS 97 and suggests an analytical procedure for reflecting actual experience and revised future assumptions in the recalculation of the estimated gross profit defined by FAS 97.

Description: The report begins with Tan's paper Source-of-Earnings Analysis under FAS97 Universal Life Accounting that defines a procedure for analyzing the sources of profit. This paper extends the analysis to consider the effect of actual experience varying from expected and the effect of those variances on assumptions for the future. Also the paper illustrates examples of the effect of changing future assumptions or unlocking on the magnitude and incidence of profits and amortization. A discussion of the paper follows. From Transactions of Society of Actuaries 1990, Vol. 42.

Description: This report presents a new set of select and ultimate expected individual life insurance lapse tables, based on inter-company experience of standard ordinary business between 1971-1972 policy anniversaries. Discussion includes overview of how the data was collected and how the tables were constructed and how they should be applied in practice.
