Description: In physics and engineering education, Fermi problems require solutions based on good approximate calculations with little or no actual data, involving making justified guesses and deducing bounds without using sophisticated tools. The idea of Fermi problems are of particular relevance to today's actuaries, as pricing, reserving, and financial reporting involve more and more complex stochastic components. The paper discusses some approximate solutions developed in academia in the spirit of Fermi problems.

Description: Read the March 2017 issue of Health Watch, published by the Health Section. Practical information for actuaries, articles impact sections, section activities.

Description: Given a financial transaction we are often interested in the number of internal rates of return [yield rates] and their location. From an actuarial point of view, the fundamental question is to identify those transactions with a single yield rate, or a single rate in some interval such as the positive reals. In this paper we are concerned with this counting problem. We survey various results concerning this problem, and provide a unifying approach together with some new insights.

Description: This panel discussion session looked at recent and proposed regulation of life insurance underwriting. Specific topics included: i. Problems with traditional underwriting classifications: privacy, disclosure, anti-discrimination, etc. 2. New and acceptable classifications: smoking, lifestyle, build, blood pressure, finances, etc. 3. Possible transition problems: existing policies, persistency, coordination of previous data with newer classes, etc.

Description: Explores the open vs. closed systems debate with regards to actuarial modeling and exposes the over-simplification. Valuable for anyone who uses models.

Description: This paper discusses the principles found in the Academy of Actuaries Committee on Financial Reporting Principles' Recommendation 4, Reinsurance Ceded by Life Insurance Companies and proposes solutions to certain problems of implementation, and identifies items where there might be differences of opinion. Followed by discussion papers submitted by 2 authors

Description: The paper o ers a simple framework for ranking the common reinsurance struc- tures in practice with the theory of stochastic orders. The basic idea is to slice the space of reinsurance structures into groups by expected loss cost to facilitate the comparisons within the group and between groups. Given the standard risk aversion assumption in economics, a spectrum of reinsurance structures with the same expected loss cost can be compared analytically with one another and sequenced based on their risk coverages under the convex order. The paper then expands the dimension of the comparison to groups of reinsurance structures with di erent expected loss costs, which can be ranked under the increasing convex order and the usual stochastic order. As such, the paper maps out the ordering for the entire space of reinsurance structures and presents it in a ma- trix format for quick reference. The implication of this stochastic ordering to reinsurance pricing is also investigated.

Description: This panel discussion, which occurred at the May 1982 Society of Actuaries meeting in Colorado Springs, led a discussion related to employer's accounting for pensions and other post-employment benefits. Topics included: 1. Present accounting rules and background in connection with pension plans 2. The purposes for pension accounting rules in general 3. The nature of pension arrangements and the implication of their character for: a. Corporate liabilities and net worth h. Periodic charges to corporate income on account of pensions 4. Effect of actuarial gains and losses and the relationship of non-penslon post-retirement benefits to pensions, from an accounting viewpoint

Description: This article delves into a new line of statistical thinking of the author, that may be useful for product development actuaries. The key concept is how product design can produce products that diversify quickly, meaning that the company can be confident of a profitable product line, based on fewer sales than might be true for other designs.

Description: This paper presents an approach to analyzing continuing care retirement community [CCRC] data, and demonstrates the methods using data from a large CCRC. It is assumed that residents make transitions among a number of states that represent the levels of care required by residents. There is randomness associated with both the transition times and the states entered at these times. The model is conveniently characterized in terms of transition intensity functions, which represent the instantaneous rates of transition between pairs of states.
