Description: Interest rate modeling is discussed in this paper with special emphasis on the long and short rate model of Brennan and Schwartz. Comment is made on an unexpected aspect of the solution of the resulting partial differential equation. Also, an analysis is made of the predictive power of the term structure of interest rates. From the Actuarial Research Clearing House 1991 Vol. 1.

Description: Asset cash flow modeling and asset assumptions are growing in importance with PBR especially considering the low interest rate environment. The Academy’s Life Practice Council and Life Valuation Committee have formed a Low Interest Rate Asset Adequacy Testing Task Force which has conducted an industry survey to raise awareness and summarize the actuarial best practices for financial reporting actuaries practicing in today’s very low interest rate environment. As the scrutiny on the asset side ratchets up, actuaries must consider how best to develop the asset assumptions as well as model the reinvestment and disinvestment strategies. Coherent assumptions and modeling practices across modeling exercises are expected while respecting the purpose of each calculation.
