On October 3, 2017 the Department of Treasury and IRS released final regulations on the mortality tables plan sponsors must use beginning in 2018 for defined benefit plans, per the Pension Protection Act of 2006. These tables are to be used to determine funding requirements, lump sum calculations and other acceleration of benefit calculations. On October of 2014, the tables were released in two reports released by the Society of Actuaries (SOA), the RP-2014 Mortality Tables Report and the Mortality Improvement Scale MP-2014 Report. Each of these reports contained new mortality assumptions recommended for valuing private-sector pension liabilities.
