Schedule of Assumptions Used [Table Text Block]

The Plans’ weighted-average assumptions used to determine the benefit obligation and net benefit cost are as follows: we base our discount rate used to compute future benefit obligations using an analysis of expected future benefit payments. The reasonableness of our discount rate is verified by comparing the rate to the rate earned on high-quality fixed income investments, such as the Moody’s Aa index, plus 50 basis points. The assumed rate of return on plan assets was not applicable as we pay plan benefits as they come due. As all Plans are curtailed, the assumed rate of compensation increase is zero.

	2012		2011		2010
Weighted average discount rate used to determine obligations	2.90	%	4.05	%	4.45	%
Weighted average discount rate used to determine net periodic pension cost	4.05	%	4.41	%	4.80	%
