Description: Traditional pension cost methods are based on the actuarial present value of future benefits [which is a mean value]. As a consequence, these cost methods are deficient because they cannot provide plan sponsors with certain valuable information such as the probability that the accumulation of a particular sequence of contributions will ultimately provide sufficient funds to pay benefits, or the size of fund needed to ensure that retirees' lifetime benefits are paid with a specified probability. In response to these deficiencies, a new family of cost methods, called a-percentile cost methods, is developed. These cost methods are based on the probability of adequately covering all participants' benefits. Expressions for the normal cost, the accrued liability and the gain are provided.

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 adopts the framework whereby pension benefits are allocated one exit point at a time in some fashion to the years of service of those persons expected to leave at each exit point. Of particular interest is an allocation by interest-adjusted salary. From the Transactions of Society of Actuaries 1994, Vol. 46.

Description: The purpose of this paper is to provide an introduction to mathematical principles applicable to pension funding under dynamic conditions of population growth, inflation, and automatic adjustment of benefits. From Transactions of Society of Actuaries 1976, Vol. 28.

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.
