The employer contributions for the years ended December 31, 2012 and 2011, were $1.1 million and $1.2 million, respectively.  The expected contribution for 2013 is $0.6 million which is expected to satisfy plan funding requirements.

The health care cost trend rate assumption affects the amounts reported.  For measurement purposes, the assumed annual rate of increase in the per capita cost of covered health care benefits was 7.5 percent for 2012 and was 8.0 percent for 2011; each year’s estimated rate was assumed to decrease gradually to 5.0 percent and remain at that level thereafter.  The annual incremental decrease was assumed to be one-half percent for both 2012 and 2011.  A one-percentage point change in assumed health care trends would have the following effects:

(in millions)	One Percentage Point Increase		One Percentage Point Decrease
Effect on total of service and interest cost components for 2012	$	2.8	$	(2.6	)
Effect on postretirement benefit obligation at December 31, 2012	48.4		(44.8		)

The Company’s actuarial valuation date is December 31.  The weighted-average discount rates used to determine the actuarial present value of the net postretirement projected benefit obligation for the years ended December 31, 2012 and 2011 were 4.00 percent and 4.25 percent, respectively.  The weighted-average discount rates used to determine the net postretirement benefit cost was 4.25 percent, 5.25 percent, and 5.75 percent for the years ended December 31, 2012, 2011, and 2010, respectively.
