Mortality Improvement Scale MP-2014 Exposure Draft

Experience Studies – Pension

The Society of Actuaries' Retirement Plans Experience Committee (RPEC) has released an exposure draft of the Mortality Improvement Scale MP-2014. This report, along with its companion document, the Society of Actuaries’ (SOA’s) RP-2014 Mortality Tables Report (see Related Links), establishes a new basis for mortality assumptions for retirement programs in the United States. These two reports represent the culmination of a comprehensive study of uninsured retirement plan mortality experience begun by the RPEC in late 2009. For pension-related purposes, the mortality projection scale presented in this report, denoted MP-2014, replaces both Scale AA, which was released in 1995, and the interim Scale BB, which was released in 2012.

The mortality improvement rates referred to in Appendix A of the exposure draft have also been provided in a spreadsheet.

The SOA solicits comments on this exposure draft. Comments should be sent to Erika Schulty, at by May 31, 2014. Please include “MP-2014 Comments” in the subject line.

Note - Errata (updated as of March 7, 2014) to the MP-2014 Exposure Draft can be found under the Related Links section on the right side of this page.
