Mortality Improvement Scale MP-2018

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 2016. For clarity, the updated mortality improvement scale based on this 2018 version of the model is called Scale MP-2018.

The Scale MP-2018 Report has been posted below along with an Excel version of Scale MP-2018.

Also below is a new version of the RPEC_2014 model, entitled RPEC_2014_v2018. This Excel-based implementation tool can be used to generate alternate improvement scales using the RPEC_2014 methodology.

Section 4.2 of the Scale MP-2018 Report describes a model based on “order-2” historical graduation. This new alternative model is entitled “RPEC_O2_v2018” and can be accessed below.
