Postretirement Benefits

A. Pension and postretirement benefit costs

In February 2012, we announced the closure of the Electro-Motive Diesel facility located in London, Ontario. As a result of the closure, we recognized a $37 million other postretirement benefits curtailment gain in the first quarter. This excludes a $21 million loss of a third party receivable for other postretirement benefits that was eliminated due to the closure. In addition, a $10 million special termination benefit expense was recognized related to statutory pension benefits required to be paid to certain affected employees.

Weighted-average assumptions used to determine net cost:

Expected return on plan assets	8.0		%	8.5		%	7.1		%	7.1		%	8.0		%	8.5		%
Rate of compensation increase	4.5		%	4.5		%	3.9		%	4.2		%	4.4		%	4.4		%

¹ Prior service cost (credit) and net actuarial loss (gain) for both pension and other postretirement benefits are generally amortized using the straight-line method over the average remaining service period to the full retirement eligibility date of employees expected to receive benefits from the plan. For other postretirement benefit plans in which all or almost all of the plan's participants are fully eligible for benefits under the plan, prior service cost (credit) and net actuarial loss (gain) are amortized using the straight-line method over the remaining life expectancy of those participants.

² Curtailments, settlements and special termination benefits were recognized in Other operating (income) expenses in the Consolidated Statement of Results of Operations.

We made $119 million and $293 million of contributions to our pension plans during the three and six months ended June 30, 2012, respectively. We currently anticipate full-year 2012 contributions of approximately $1 billion, of which $570 million are required contributions. We made $104 million and $235 million of contributions to our pension plans during the three and six months ended June 30, 2011, respectively.

B. Defined contribution benefit costs

On January 1, 2011, matching contributions to our U.S. 401(k) plan changed for certain employees that are still accruing benefits under a defined benefit pension plan. Matching contributions changed from 100 percent of employee contributions to the plan up to six percent of their compensation to 50 percent of employee contributions up to six percent of compensation. For U.S. employees whose defined benefit pension accruals were frozen as of December 31, 2010, we began providing a new annual employer contribution in 2011, which ranges from three to five percent of compensation, depending on years of service and age.

Total company costs related to our defined contribution plans were as follows:
