The formal adoption of principle-based reserving (PBR) in the U.S. is coming with a likely effective date of January 1, 2017. This paper considers sample blocks of business representative of current cohorts that are subject to the new requirements. We attempted to do the calculations prescribed by Actuarial Guideline 48, considering both level term business and universal life business with secondary challenges. The findings provide an indication as to what issues the insurance industry might need to anticipate as it prepares for the wider implementation of PBR in the coming years.
