Long-term care first principles modeling: Advantages and enhancements in modeling

This article by Milliman actuaries is the fourth in a series on long-term care (LTC) first principles modeling. The first article in the series, released in March 2016, introduced the topic and set the stage for the series of case study discussions that would follow. The second and third articles in the series, released in June 2016 and November 2016, examined the development of mortality and lapse assumptions, respectively, for use in an LTC first principles model. The latest article builds on these discussions with a look into how a first principles model, using these assumptions, can enhance and simplify the modeling of LTC projections. Once the groundwork of developing the key assumptions is completed, first principles models provide an improved platform for modeling by automating many processes and making refinements both easier to implement and more varied.

Long-term care first principles modeling: Lapse assumptions

In this article, Milliman consultants discuss issues related to developing healthy life lapse rates using a long-term care (LTC) first principles model. As noted throughout the article, the common assumption that the ultimate total life lapse rate reaches a constant level produces an increasing healthy life lapse rate by duration. Alternatively, if the healthy life lapse rate remains constant once it reaches an ultimate level, that would imply that the total life lapse rate continues to decrease over time. The article also examines how mortality and lapse assumptions interact and the importance that developing an appropriate mortality assumption can have on setting lapse rate assumptions.

Developing mortality assumptions for LTC first principles modeling

The development of separate mortality assumptions for healthy and disabled lives creates challenges for insurers using a long-term care (LTC) first principles model. In this article, Milliman actuaries discuss those challenges as well as their experience working with companies to overcome them. They also explore the advantages and opportunities of an enhanced approach to modeling mortality in a first principles context.
