Pension Plans
Employee Benefit Plans:

The Company has a pension plan (the Plan) covering a portion of its work force. The Plan is a defined benefit plan pursuant to which pension payments are based primarily on years of service and employee compensation near retirement. The Plan is closed to new participants and benefits were frozen as of December 31, 2013. As a result, eligible employees retain all of the vested rights as of the effective date of the freeze, while additional benefits no longer accrue. Plan assets are comprised principally of fixed maturity securities, common stocks and short-term investments. No cash contributions were made to the pension plan in the first quarters of 2017 or 2016. Additional cash contributions of $2.8 are expected to be made in the remaining portion of calendar year 2017.
