Principle-Based Reserving

Background

Last Updated: 8/1/2025
IssueAll accredited states have revised their Standard Valuation Law (#820) and the Standard Nonforfeiture Law for Life Insurance (#808) to implement principle-based reserving (PBR) which became an accreditation standard Jan. 1, 2020. Effective Jan. 1, 2017, the Valuation Manual became operative. PBR was a significant change in underlying laws and regulations to solve a problem created by past regulatory frameworks. The issue lies with laws and guidance on how a life insurer is required to calculate reserves. Life insurers set aside funds, known as reserves, to pay insurance claims when they become due. Prior to PBR, static formulas and assumptions were used to determine these reserves as prescribed by state laws and regulations. However, sometimes this rules-based approach left a life insurer with excessive reserves for certain insurance products and inadequate reserves for others. The solution was to "right-size" reserve calculations by replacing a rules-based approach with a principle-based approach. Under PBR, life insurers are required to hold the higher of (a) a minimum reserve using prescribed assumptions or (b) reserves which consider a wide range of future economic conditions, computed using credible insurer experience factors specific to an insurer, such as mortality, policyholder behavior and expenses.

Actions

The Life Actuarial (A) Task Force (LATF) is continuing to oversee edits to, and publication of, the Valuation Manual. Recent initiatives include:

  • Reviews of life insurance companies’ PBR valuations are being conducted annually by the Valuation Analysis (E) Working Group (VAWG). 

  • LATF made revisions to VM-50 and VM-51 to enhance the quality and relevance of the life insurance mortality experience data collected.

  • LATF also adopted VM-21, Requirements for Principle-Based Reserves.  

  • An amendment to the Valuation Manual to implement VM-22, Requirements for Principle-Based Reserves for Non-Variable Annuities, was adopted by LATF and is expected to be effective January 2026 with a three-year implementation period before becoming mandatory for all new issues in January 2029.

  • A new generator of economic scenarios (GOES) will be effective for  January 2026 in all PBR reserve frameworks.
