Mortality Improvement Scale MP-2020

The Retirement Plans Experience Committee of the Society of Actuaries (RPEC) is pleased to present this annual update to the RPEC_2014 model and its corresponding mortality improvement scales. This new version of the model reflects historical U.S. population mortality experience through 2018. For clarity, the updated mortality improvement scale based on this 2020 version of the model is called Scale MP-2020.

The Scale MP-2020 Report has been posted below along with an Excel version of Scale MP-2020.

Also below is a new version of the RPEC_2014 model, entitled RPEC_2014_v2020. This Excel-based implementation tool can be used to generate alternate improvement scales using the RPEC_2014 methodology.

Subsection 4.3 of the Scale MP-2020 Report describes a model based on “order-2” historical graduation, which was released for the first time in 2018. This alternative model has been updated with U.S. population experience through 2018. The new version is entitled “RPEC_O2_v2020” and can be accessed below.
