Pension Plan

11. PENSION PLAN

The Company’s Canadian subsidiary sponsors a defined benefit pension plan at one of its locations in which a majority of its employees are members. The subsidiary funds 100% of all contributions to the plan. The benefits, or the rate per year of credit service, are established by the Company and updated at its discretion.

The components of the expense the Company incurred under the pension plan are as follows (in thousands):

	Three Months Ended March 31,
	2016			2015
Current service cost, net of employee contributions	$	11		$	15
Interest cost on accrued benefit obligation		24			27
Expected return on plan assets		(39	)		(41	)
Amortization of transitional obligation		2			3
Amortization of past service costs		2			2
Amortization of net actuarial gain		8			10
Total cost of benefit	$	8		$	16

The Company’s policy is to fund the pension plan at or above the minimum level required by law. The Company made $22 and $24 of contributions to its defined benefit pension plan during the three months ended March 31, 2016 and 2015, respectively. Changes in the discount rate and actual investment returns that are lower than the long-term expected return on plan assets could result in the Company making additional contributions.
