Benefit obligations assumptions: |  |  |  |  |  |  |  |  |  |  |  |
Discount rate |  | 4.40 | % |  | 5.60 | % |  | 4.00 | % |  | 3.40 | % |  | 4.20 | % |  | 3.75 | %
Rate of compensation increase |  | 3.00 | % |  | 3.00 | % |  | — |  |  | — |  |  | — |  |  | — |
Initial medical trend rate 1 |  | — |  |  | — |  |  | 8.00 | % |  | — |  |  | 8.50 | % |  | — |
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 December 31, 2012 and December 31, 2011. A one-percentage-point increase in the assumed medical trend rates would increase the accumulated postretirement benefit obligation of the Union VEBA by $41.1 and $50.5 at December 31, 2012 and December 31, 2011, respectively. A one-percentage-point decrease in the assumed medical trend rates would decrease the accumulated postretirement benefit obligation of the Union VEBA by $33.4 and $40.8 at December 31, 2012 and December 31, 2011, 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 are:
|  | Canadian Pension Benefits |  | VEBA Benefits
|  | 2012 |  | 2011 |  | 2010 |  | 2012 |  | 2011 |  | 2010
|  |  |  |  |  |  |  | Union VEBA |  | Salaried VEBA |  | Union VEBA |  | Salaried VEBA |  | Union VEBA |  | Salaried VEBA
Net periodic benefit cost assumptions: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Discount rate |  | 5.60 | % |  | 5.70 | % |  | 6.70 | % |  | 4.20 | % |  | 3.75 | % |  | 5.25 | % |  | 4.70 | % |  | 5.80 | % |  | 5.40 | %
Expected long-term return on plan assets 1 |  | 4.60 | % |  | 5.40 | % |  | 5.40 | % |  | 7.25 | % |  | 7.25 | % |  | 6.00 | % |  | 7.25 | % |  | 4.75 | % |  | 7.25 | %
Rate of compensation increase |  | 3.00 | % |  | 3.50 | % |  | 3.50 | % |  | — |  |  | — |  |  | — |  |  | — |  |  | — |  |  | — |

_____________________
1 | The expected long-term rate of return assumption is based on the historical 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, 5% by 2019 and 5% by 2019 for 2012, 2011 and 2010, respectively. 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 $2.5, $2.7 and $2.7 for 2012, 2011 and 2010, 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, $2.1, and $2.2 for 2012, 2011 and 2010, respectively.

_____________________________
1 | The actuarial gain relating to the VEBA plans in 2012 was primarily comprised of (i) a gain of $42.2 due to lower actual prescription drug claim cost and a change in Retiree Drug Subsidy assumption in 2012 in the Union VEBA, (ii) a gain of $16.2 due to changes in census data for both VEBA plans, (iii) a gain of $9.6 relating to a change in the participant marital status assumption in the Union VEBA and (iv) a gain of $11.0 relating to a change in the assumption for annual benefit utilization per participant in the Salaried VEBA, partially offset by a loss of $9.7 due to decrease in discount rates used to determine benefit obligations for both VEBA plans. The actuarial loss relating to the VEBA plans in 2011 was comprised of (i) a loss of $31.4 resulting from an increase in benefit cost for plan participants, (ii) a loss of $53.5 resulting from a decrease in discount rates used to determine benefit obligations for both VEBA plans and (iii) a loss of $11.9 resulting from change in actuarial assumptions.
2 | In January 2005, the Department of Health and Human Services’ Centers for Medicare and Medicaid Services (CMS) released final regulations governing the Medicare prescription drug benefit and other key elements of the Medicare Modernization Act that went into effect January 1, 2006. The Union VEBA is eligible for the Retiree Drug Subsidy because the plan meets the definition of actuarial equivalence and therefore qualifies for federal subsidies equal to 28% of allowable drug costs. As a result, the Company has measured the Union VEBA’s obligations and costs to take into account this subsidy.
3 | With respect to the Prepaid benefit of $360.6 relating to the VEBAs at December 31, 2012, $365.9 was included in Net asset in respect of VEBA and $5.3 was included in Net liability in respect of VEBA on the Consolidated Balance Sheet. With respect to the Prepaid benefit of $124.1 relating to the VEBAs at December 31, 2011, $144.7 was included in Net asset in respect of VEBA and $20.6 was included in Net liability in respect of VEBA on the Consolidated Balance Sheets.
