Description: This paper gives a mathematical proof of the frequently expressed concept that under the entry age normal method of valuing a retirement plan, the salary scale applies retroactively. That is, it demonstrates that the valuation of a plan assumes that all past contributions to the plan were based on salaries which, when projected by the salary scale, reproduce the present level of income. The concept of retroactivity is also applied to a situation where there is a constant offset such as the social security benefit. In addition, the paper discusses the effect on this liability resulting from an increase in salary in excess of the increase provided by the salary scale and the effect on the liability of certain types of salary-scale changes.

Description: A review of the actuarial aspects of Cash Balance Retirement Plans and original actuarial research regarding the design and valuation of such plans.

Description: This paper presents a history of traditional topics like actuarial cost methods and assumptions, the history of past inquiries into the dynamic and stochastic nature of pension costs, and the perceptions and concerns of pension actuaries of the past. From The Future of Pension Plan Funding and Disclosure Monograph, M-RS05-1.

Description: This article uses a Bayesian approach to persistency to explore pension cost projection variability. The analysis includes the specifications of the model and how the model might be used to generate confidence intervals for pension cost projections.

Description: A mathematical model is described which facilitates the comparison of different pension funding methods. Rates of return are assumed firstly to be random and then to be represented by an autoregressive model for the corresponding force of interest. From Actuarial Research Clearing House 1990, Vol. 1.

Description: The purpose of this paper is to discuss modified cost methods that have been proposed for small-plan valuations, The first portion of the paper deals with criteria for choosing a cost method. The next portions deal with small-plan characteristics and the potential shortcomings of conventional cost methods when applied to these plans. The final portion discusses two classes of modified cost methods that have been proposed for circumventing these shortcomings. From Transactions of Society of Actuaries 1983, Vol. 35.

Description: This summary is intended to provide the pension actuary with guidance in interpreting and using the termination and retirement information in the 2003 SOA Pension Plan Termination and Retirement Study. The tables in the study were developed based on 1.7 million life years of data from 112 plans collected primarily from actuarial consulting firms for the period 1995 – 2000.

Description: Panelists at this session of the SOA 1998 Maui II Spring Meeting discuss details of the turnover assumption for the valuation of pension plans. A recently released SOA Turnover Study is discussed.

Description: Financing a defined benefit pension plan can be accomplished in various ways. With the help of a one-life example, this paper gives an elementary actuarial perspective of the problems that arise when a new defined benefit pension plan is initiated, and of the various actuarial concepts and methods developed to ascertain the cost of these pension benefits. The paper shows the range of the cost alternatives conceptually available upon creation of the pension plan. Actuarial formulas are provided in footnotes. The paper is intended as an introduction to defined benefit pension cost determination as well as an elementary example which may be of value in explaining cost alternatives to an actuary's client.

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.
