Compensation and Retirement Disclosure [Abstract] |
Schedule of Assumptions Used to Determine Benefit Obligations | Assumptions used to determine benefit obligations as of the periods presented were as follows:
|  | Canadian Pension Benefits |  | VEBA Benefits
|  | December 31, 2014 |  | December 31, 2013 |  | December 31, 2014 |  | December 31, 2013

Rate of compensation increase |  | 3.00 | % |  | 3.00 | % |  | — |  |  | — |  |  | — |  |  | — |
Initial medical trend rate 1 |  | — |  |  | — |  |  | 7.00 | % |  | — |  |  | 7.50 | % |  | — |
Ultimate medical trend rate 1 |  | — |  |  | — |  |  | 5.00 | % |  | — |  |  | 5.00 | % |  | — |
_____________________
1 | The medical trend rate assumptions used for the Union VEBA were provided by the Union VEBA and certain industry data were provided by the Company's actuaries. The trend rate is assumed to decline to 5% by 2019 at each of December 31, 2014 and December 31, 2013. A one-percentage-point increase in the assumed medical trend rates would increase the accumulated postretirement benefit obligation of the Union VEBA by $37.7 and $27.8 at December 31, 2014 and December 31, 2013, respectively. A one-percentage-point decrease in the assumed medical trend rates would decrease the accumulated postretirement benefit obligation of the Union VEBA by $29.9 and $22.7 at December 31, 2014 and December 31, 2013, respectively.
Schedule of Assumptions Used to Determine Net Periodic Benefit Cost (Income) | Assumptions used to determine net periodic benefit cost (income) for the years ended December 31 were:
|  | Canadian Pension Benefits |  | VEBA Benefits
|  | 2014 |  | 2013 |  | 2012 |  | 2014 |  | 2013 |  | 2012
|  |  |  |  |  |  |  | Union VEBA |  | Salaried VEBA |  | Union VEBA |  | Salaried VEBA |  | Union VEBA |  | Salaried VEBA
Discount rate |  | 4.90 | % |  | 4.40 | % |  | 5.60 | % |  | 4.70 | % |  | 4.20 | % |  | 4.00 | % |  | 3.40 | % |  | 4.20 | % |  | 3.75 | %
Expected long-term return on plan assets 1 |  | 4.75 | % |  | 4.50 | % |  | 4.60 | % |  | 6.75 | % |  | 7.75 | % |  | 6.25 | % |  | 7.25 | % |  | 7.25 | % |  | 7.25 | %
Rate of compensation increase |  | 3.00 | % |  | 3.00 | % |  | 3.00 | % |  | — |  |  | — |  |  | — |  |  | — |  |  | — |  |  | — |
Initial medical trend rate 2 |  | — |  |  | — |  |  | — |  |  | 7.50 | % |  | — |  |  | 8.00 | % |  | — |  |  | 8.50 | % |  | — |
Ultimate medical trend rate 2 |  | — |  |  | — |  |  | — |  |  | 5.00 | % |  | — |  |  | 5.00 | % |  | — |  |  | 5.00 | % |  | — |
_____________________
1 | The expected long-term rate of return assumption is based on the targeted investment portfolios provided to the Company by the VEBAs’ trustees.
2 | The medical trend rate assumptions used for the Union VEBA, which is currently paying certain prescription drug benefits, were provided by the Union VEBA and certain industry data were provided by the Company's actuaries. The trend rate is assumed to decline to 5% by 2019 for each of 2014, 2013 and 2012. A one-percentage-point increase in the assumed medical trend rates would increase the aggregate of the service and interest cost components of net periodic benefit costs by $2.6, $2.0 and $2.5 for 2014, 2013 and 2012, respectively. A one-percentage-point decrease in the assumed medical trend rates would decrease the aggregate of the service and interest cost components of net periodic benefit costs by $2.0, $1.5 and $2.0 for 2014, 2013 and 2012, respectively.

_____________________________
1 | The prior service cost relating to the VEBAs in 2014 was primarily comprised of (i) a loss of $60.5 due to an increase in the healthcare premium reimbursement benefit in the Union VEBA; (ii) a loss of $15.9 resulting from the addition of a new death benefit starting in 2015 for plan participants in the Union VEBA; and (iii) a loss of $14.0 due to an increase in the annual healthcare reimbursement benefit starting in 2015 for plan participants in the Salaried VEBA.
The prior service cost relating to the VEBAs in 2013 was primarily comprised of a loss of $63.8 due to the addition of a new healthcare premium reimbursement benefit starting in 2014 in the Union VEBA and a loss of $20.8 resulting from an increase in the existing benefits reimbursement rates starting in 2014 for plan participants in both VEBAs.
2 | The actuarial gain relating to the VEBAs in 2014 was primarily comprised of (i) a gain of $53.6 due to projected lower benefit utilization; (ii) a gain of $18.0 due to projected lower drug claim cost in the future because of lower than expected drug claim costs in 2014 in the Union VEBA; (iii) a gain of $0.4 due primarily to a reduction in administrative cost in the Union VEBA; partially offset by (iv) a loss of $45.0 due primarily to reductions in the discount rates; and (v) a loss of $37.2 due primarily to updated actuarial mortality rates in both VEBAs.
The actuarial gain relating to the VEBAs in 2013 was primarily comprised of (i) a gain of $54.9 due to projected lower drug claim cost in the future because of lower than expected drug claim costs in 2013 in the Union VEBA; (ii) a gain of $30.5 due to a decrease in discount rates used to determine benefit obligations for both VEBAs; (iii) a gain of $8.0 due primarily to a higher than expected mortality rate in the Union VEBA; partially offset by (iv) a loss of $2.7 due primarily to an increase in administrative cost in the Union VEBA.
3 | The Union VEBA is eligible for the retiree drug subsidy of the Medicare Modernization Act that went into effect January 1, 2006. As a result, the Company has measured the Union VEBA’s obligations and costs to take into account this subsidy.
4 | Prepaid benefits of $322.9 at December 31, 2014 was comprised of $340.1 presented as Net asset of VEBAs on the Consolidated Balance Sheet related to the Union VEBA, offset by $17.2 presented as Net liability in respect of VEBA related to the Salaried VEBA. Prepaid benefits of $406.0 relating to both VEBAs at December 31, 2013 were presented as Net asset of VEBAs on the Consolidated Balance Sheet.
5 | The Company accrued a liability for a variable cash contribution of $13.7 to the VEBAs with respect to calendar year 2014, which will be paid in the first quarter of 2015. The Company accrued a liability for a variable cash contribution of $16.0 to the VEBAs with respect to calendar year 2013, which was paid in the first quarter of 2014.
6 | The presentation of Change in benefit obligation in the table above has been revised from the prior year presentation to reflect separate amounts for actuarial gains and losses and prior service costs related to plan amendments. This information was presented in a footnote to the table in the prior year. The 2013 balances shown above were adjusted to reflect this reclassification. The impacts to the prospective amortization of Prior service cost and Actuarial loss (gain) were not material.
