Post-retirement Plans

We have a post-retirement healthcare and other benefits plan that is available to certain of our employees who satisfy certain age and service requirements. The net periodic benefit credit of this plan consisted of the following components:

	Three Months Ended March 31,
	2015			2014
	(In thousands)
Service cost – benefit earned during the period	$	424		$	224
Interest cost on projected benefit obligations	205			159
Amortization of prior service credit	(871		)	(1,074		)
Amortization of net loss	46			—
Net periodic post-retirement credit	$	(196	)	$	(691	)

Additionally, we had a program that provided transition benefit payments to certain employees that participated in a previously terminated defined benefit plan. The program extended through 2014 and provided payments subsequent to year-end provided the employee was employed by us on the last day of each year. The payments are based on each employee's years of service and eligible salary. Transition benefit costs under this program were $0.3 million and $2.6 million for the three months ended March 31, 2015 and 2014, respectively. In March 2015, we paid all amounts owed to plan participants of $11.0 million.
