Description: Discussion of the proportion of the increase in life expectancy at a given age that can be attributed to the change in mortality rates at and over some higher age and methods as to how this proportion can be measured. Followed by several discussion papers submitted

Description: This is a discussion of the paper, On Computing the Probability that Exactly k of n Independent Events will Occur by Robert P. White and T. N. E. Greville. From Transactions of Society of Actuaries 1959, Vol. 11, No. 29 AB.

Description: This paper presents discrete interpolation formulas, specifically a new method of deriving some existing formulas. The paper uses graduation theory in the interpolation method. Also include is a discussion of the paper. From Transactions of Society of Actuaries 1949, Vol. 1, No. 1.

Description: In this paper two theorems concerning the optimality of the perfect-fit and perfect-smoothness graduations are proved. Two examples are presented and some difficulties with regard to computational feasibility are reviewed. A discussion of the paper follows. From Transactions of Society of Actuaries 1978, Vol. 30.

Description: This paper presents formulas for the L-Function and shows this function has applications in computing survival rates free from the influence of a given cause of death.

Description: In general, a complete annuity of one per annum may be defined as a curtate annuity of one per annum with an additional final payment, made a fraction of a year after the last payment of one, representing the accrued portion of the succeeding payment not yet due. This paper explores the relationships which occur if compound interest is used instead of simple interest to calculate the final partial payment.

Description: This paper explains a method of computation for the probability of survival which may often be more expeditious than the methods in common use, particularly when the number of lives is large. From Transactions of Society of Actuaries 1959, Vol. 11, No. 29 AB.

Description: This section contains book reviews and summaries of recently published works on subjects including demography, savings in the U.S., life company state examinations, private pensions, Industrial insurance, medical care, and union welfare plans.

Description: This section presents book reviews and summarizes recent publications on subjects that include U.K. social insurance, financing of hospital care, state examinations of life companies, approximate valuation of life and health insurance, mortality forecasting, and valuing estate tax.

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.
