Mortality Improvement Scale MP-2017

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 2015. For clarity, the updated mortality improvement scale based on this 2017 version of the model is called Scale MP-2017.

The Scale MP-2017 Report has been posted below along with an Excel version of Scale MP-2017.

Also below is a new version of the RPEC_2014 model, entitled RPEC_2014_v2017. This Excel-based implementation tool can be used to generate alternate improvement scales using the RPEC_2014 methodology.

Similar to previous years, this publication also includes a set of factors that can be used to adjust the RP-2014 values to base year 2006. These factors can be found below.

The final items listed below are links to the home pages for Scale MP-2016 (the most recently published scale prior to MP-2017), the original Scale MP-2014, and the RP-2014 Mortality Tables.
