The benefits for the Defined Contribution Restoration Plan were frozen effective July 1, 2018. Employees hired after this date are not eligible for this benefit plan. In addition, current participants receive no further compensation credits after that date, with the last award year being 2017. Annual interest credits will continue to be made in accordance with the terms of the plan. This freezing of the plan triggered a curtailment gain of $416. The curtailment resulted in a plan remeasurement, decreasing the plan liabilities by $2,235 at June 30, 2018.
