In 2015, the Society of Actuaries updated the mortality tables to be used in calculating defined pension plans’ benefit obligations. At that time, the IRS did not make a change in the mortality tables to be used for funding purposes. Many plan sponsors and administrators were expecting the IRS to follow suit for plan valuation dates occurring during 2017. On September 2, 2016, the IRS issued Notice 2016-50, which announced the new mortality tables to be used for that period. The tables continue to be based on expected mortality as of 2000, meaning that there were no significant changes. The deferral of implementing any major modifications allows plan sponsors to continue to prepare for the adjustments that will likely come in 2018. Plan sponsors will be able to prepare for the future increase in cash flow requirements and look at other possible strategies before the implementation, such as a terminated vested buyout amendment.
