Pension and Post-retirement Plans:

(7) Pension and Post-retirement Plans:  The Company has defined benefit and defined contribution pension plans that cover substantially all non-bargaining unit and certain bargaining unit employees.  The Company also has unfunded non-qualified plans that provide benefits in excess of the amounts permitted to be paid under the provisions of the tax law to participants in qualified plans.  The assumptions related to discount rates, expected long-term rates of return on invested plan assets, salary increases, age, mortality and health care cost trend rates, along with other factors, are used in determining the assets, liabilities and expenses associated with pension benefits.  Management reviews the assumptions annually with its independent actuaries, taking into consideration existing and future economic conditions and the Company’s intentions with respect to these plans.  Management believes that its assumptions and estimates for 2013 are reasonable. Different assumptions, however, could result in material changes to the assets, obligations and costs associated with benefit plans.

The components of net periodic benefit cost recorded for the first three months of 2013 and 2012 were as follows (in millions):

	Pension Benefits						Post-retirement Benefits
	2013			2012			2013		2012
Service cost	$	0.7		$	1.4		$	0.3	$	0.3
Interest cost	2.1			2.9			0.5		0.8
Expected return on plan assets	(2.7		)	(2.7		)	—		—
Amortization of net loss	2.0			0.9			0.2		0.5
Amortization of prior service cost	(0.6		)	—			—		—
Net periodic benefit cost	$	1.5		$	2.5		$	1.0	$	1.6

In 2013, the Company expects cash contributions to its defined pension plans to total approximately $3.5 million, all of which has yet to be contributed as of March 31, 2013.
