The return on the marginal surplus committed to support the variability of a proposed reinsurance contract is used to derive an appropriate risk load for reinsurers.

The conditional efficiency of an unspecified portfolio of a value-weighted stock index and a long-term government bond index is rejected in a framework that allows the factor risk-premia, asset betas, and residual variances to vary with the levels of observable state variables.

This paper considers the rates of return appropriate for use in the discounting of loss reserves. The author reviews some of the modern theory of term structure of bond interest rates. Discount factors for fixed term single payment future liabilities are developed for the case in which those liabilities are supported by a bond portfolio, and the factors are interpreted within the term structure theory.

The common theme which appears to have evolved in the actuarial methodology for determining self-insurance funding contributions can be described in basic terms as a two-step process: (a) estimating expected retained losses for the self-insured entity and (b) estimating a safety margin or risk loading to maintain funding at a selected high level of confidence. Variations on this general theme abound.

Many criteria for choosing optimal reinsurance treaties have the common property that a treaty is considered preferable to another if it is lower in stop-loss order, which means that it generates uniformly lower stop-loss premiums. Such criteria include maximizing utility of wealth, minimizing ruin probability and many others.

The meaning of consistency of increased limit factors is considered and a new consistency condition is proposed It is shown that the three major measures of risk satisfy the new consistency condition with no restrictions. the problems of specifying unique risk loaded rates for high limits are discussed. A revised subtraction formula is given. Risk "Profile" curves are suggested as a method to convey the subjective aspect of risk load.

This paper values a contingent claim to discrete stochastic cash flows generated by a Poisson arrival process with a randomly varying intensity parameter. In the most general case, both the size and the arrival intensity of cash flows may correlate with state variables in a continuous time economy.

Two ways of estimating ultimate incurred losses are loss based and exposure based. The former uses a factor applied to losses emerged to date; the latter bases the loss estimate on the exposure, and ignores emerged losses. A hybrid is the Bornheutter–Ferguson method, which adds the emerged losses to an appropriate percentage of the exposure based estimate. This paper considers a weighting of these three estimators using credibility concepts.

The purpose of this paper is to develop a simple model for determining distributions of present value estimates of aggregate losses. Three random components of the model that will be described are aggregate losses, payout patterns, and interest rates.
In addition, this paper addresses the impact of timing and investment variability on risk margin/solvency requirements.

In his insightful and ground-breaking essay entitled The Structure of Scientific Revolutions, Thomas S. Kuhn discussed the notion of scientific advancement. In particular, he introduces the idea of a paradigm, a body of knowledge and beliefs which provides direction for research.

Current accounting techniques for P&C Insurance companies do not represent the real values for assets and liabilities. Discounting is now a major issue, which has been brought more to the fore with the Tax' Reform Act of 1986. Apart from some special situations* unpaid liabilities are represented at their undiscounted value.
Cash flow techniques are becoming recognized as realistic methods of valuation.

This report has been prepared by the Long Range Planning Subcommittee of the Syllabus Committee at the request of the Board of Directors of the CAS. The purpose is to evaluate the educational content of the syllabus from the standpoint of the educational needs of future actuaries. The subcommittee has been reviewing Syllabus content for several years in terms of a long range comprehensive plan for educating actuaries.

Insurers typically earn greater profits on policies that have been with the insurer for a number of renewal cycles than on new business. This tendency is known as the aging phenomenon and is believed to occur on all lines of business. Although the aging phenomenon is common knowledge, no mathematical methods for incorporating this phenomenon into pricing decisions have been documented.

The subject of the effect of trend on excess of loss coverages has been addressed quite frequently in the Proceedings over the years. Several authors have made the point that with a fixed retention and uniform trend by size of loss, expected excess losses increase proportionally much more than indicated by the general rate of inflation.

Reinsurance treaties defined as generalizations of the classical largest claims reinsurance covers are investigated with respect to the associated risk, defined as the variance of the insurer’s retaining total claims amount. Instead of the unhandy variance corresponding handier asymptotic expressions are used. With these an asymptotic efficiency measure for comparing two such reinsurance covers is defined.

Arjas presents a stochastic model of the casualty insurance mechanism that makes use of martingales and "point processes." This differs from the collective risk approaches (frequency and severity) and also from the more ad hoc forecast models that are based solely on the development triangles. There appear to be significant practical questions regarding the underlying distributions that must be answered before this can be used in practice.

The intent of this paper is to provide some basic tools for the measurement and management of interest rate risk. Interest rate risk has been present in the P/C industry since inception of the first insurance policy. Recent (1980’s) results of the P/C industry have heightened the awareness of the importance of investment income and its associated risk. Proper management of this risk is a key to the economic success of a P/C company.

The purpose of the paper is to develop a method of calculating the aggregate loss distribution of excess claims based on a formula described in the book Risk Theory by Beard, Pentikainenen, and Pesonen. This formula requires that the claim frequency distribution satisfy a certain recursive relationship.
