Pension benefits for all salaried employees are frozen, resulting in an assumption for the rate of compensation increase of zero. In addition to the salaried benefits being frozen, there are currently no scheduled increases in pension benefit rates applicable to past service covering the minimal number of hourly employees who continue to accrue benefits.
[4] Prior to the remeasurements of our qualified defined benefit pension plan on April 25, 2018, and August 10, 2018, the discount rates were 3.40% and 4.05%, respectively, and the expected rates of return on plan assets were 4.75% and 4.50%, respectively. The discount rate and expected rate of return on plan assets after the August 10, 2018 remeasurement were 3.95% and 3.85%, respectively.
