13.	Postretirement Medical Benefits

We provide certain medical and dental care benefits to eligible retired U.S. and Canadian employees. Eligibility for U.S. employees is limited to employees hired before 1995. Under the U.S. plan, a Health Reimbursement Account ("HRA") was established beginning January 1, 2009 for each qualified U.S. retiree. Monthly, a fixed amount is credited into the HRA to cover both medical and dental costs for all current and future eligible retirees. Under the Canadian plan, retiree medical and dental benefits are funded in a pay-as-you-go basis.

In the second quarter 2011, we announced that our postretirement medical benefit plans to substantially all eligible U.S. and Canadian employees will terminate on December 31, 2016. There will be no change to the eligibility or plan provided to the 64 former union employees. The remeasurement of the postretirement medical benefit plans resulting from these benefit modifications generated a $14.4 million reduction in the accumulated postretirement benefit obligation and a $3.6 million curtailment gain. The remaining unrecognized prior service cost is being amortized on a straight-line basis over the remaining term of the plan. The discount rate assumptions used to determine the remeasurement of the costs and benefit obligation related to our U.S. and Canadian postretirement plans were 1.87% and 3.75%, respectively. These rates reflect the shorter duration of our obligation as a result of the negative plan amendments. The $3.6 million curtailment gain is included in selling, general and administrative expenses in the consolidated statements of operations.

The benefit obligation, funded status, and amounts recognized in the consolidated financial statements for our postretirement medical benefit plans as of and for the years ended December 31, 2012 and 2011, were as follows (in thousands):

Actuarial assumptions used to determine costs and benefit obligations related to our U.S. postretirement plan are as follows:

	December 31,
	2012			2011			2010
Discount rate		0.55	%		1.30	%		5.35	%

Actuarial assumptions used to determine costs and benefit obligations related to our Canadian postretirement plan are as follows:

	December 31,
	2012			2011			2010
Discount rates		3.00	%		3.00	%		5.00	%
Current medical cost trend rate		8.57	%		9.29	%		10	%
Ultimate medical cost trend rate		5	%		5	%		5	%
Year trend rate declines to ultimate		2017			2017			2017

The Company's discount rates are determined by considering current yield curves representing high quality, long-term fixed income instruments. We set our discount rate for the U.S. plan based on a review of the Citigroup Pension Discount Curve and the duration of expected payments in the plan. We set our discount rate for the Canadian plan based upon similar benchmarks in Canada. The lower discount rates used in 2012 and 2011 reflect the shorter duration of our obligation as a result of the plan amendments announced in the second quarter of 2011.

The following benefit payments which reflect expected future service, as appropriate, are expected to be paid (in thousands):


2013	$	1,980
2014		1,187
2015		1,215
2016		1,268
2017		62
Years 2018 – 2022		198

Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plans. A one-percentage-point change in assumed health care cost trend rates would have the following effects for 2013 (in thousands):

	1-Percentage- Point Increase		1-Percentage- Point Decrease
Effect on total of service and interest cost components	$	1	$	(1	)
Effect on postretirement benefit obligation		37		(36	)
