Description: The primary purpose of this paper is to set forth one method of evaluating vested pension costs and to suggest a simple way for the actuary to make provision in his pension cost calculations for specific vesting schedules.

Description: This paper presents a theoretical treatment of the determination of the cost of vesting by a method not hitherto demonstrated to the Society. From Transactions of Society of Actuaries 1966, Vol. 18, Pt. 1, No. 52.

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: This paper uses a Bayesian approach to persistency to explore retirement cost projection variability. The analysis is divided into two parts. In the first part a subjective population projection model is developed, based on a beta-binomial distribution for the number of participants persisting through a given age. Probability statements regarding such items as the number of participants at a given age and the distribution of retirees are developed. The second part shows how the model might be used to generate confidence intervals for retirement cost projections. Both the single-entry-age case and the multiple-entry-age case are considered.

Description: This paper addresses how to explain yearly fluctuations and computed pension cost in terms of deviations of actual from expected experience. It presents a method for deriving gain-an-loss analysis formulas directly from the valuation formulas and shows that the analysis is implicitly defined by the valuation formulas, rather than something which can be considered apart from them. This method can be used to attack both individual and aggregate cost methods and the development of exact analysis formulas provides not only the basis for computation but also valuable insight into the mechanisms by which cost methods adjust computed costs to reflect actual experience.

Description: This paper examines some of the methods used to determine the value of the assets held by a pension fund and used in actuarial valuations to determine the required contributions for a pension plan. From Transactions of Society of Actuaries 1968, Vol. 20, Pt. 1, No. 58.

Description: This paper deals with the selection of appropriate interest and inflation assumptions, which is one of the most important considerations in the valuation of a defined benefit pension plan. The paper begins by describing a simplified model in which the only important consideration is the selection of an appropriate differential between interest and inflation assumptions. The discussion then considers some situations that might lead the actuary to attempt to select a realistic level of interest and inflation assumptions, in addition to an appropriate differential. The author's conclusion is that in some situations the absolute level of the interest and inflation assumptions can be all but meaningless, and the differential between the two assumptions is the important factor. In other situations the use of this technique will produce serious inaccuracies in the valuation results. As always, the actuary must analyze each situation in order to determine which of the available techniques will produce the best results with the least effort, given the degree of accuracy required.

Description: This paper describes the actuarial valuation method for pension plans, the formulas and assumptions used, and the way these assumptions might be chosen. A case study is presented. Followed by several discussion papers submitted

Description: This paper surveys the actuarial techniques connected with salary scale mathematics for the valuation of defined benefit pension plans. Followed by several discussion papers submitted

Description: The objective of this paper, prepared by the Society of Actuaries Committee on Pension Principles and Related Research, is to examine the advantages and disadvantages of using select and ultimate interest and salary scale assumptions in the valuation of defined benefit pension plans. The technical issues involved and the effect of such assumptions on the incidence of plan cost are also studied. From Transactions of Society of Actuaries 1985, Vol. 37.
