16.  Employee Benefit Plans

 

Defined Benefit Pension and Other Postretirement Benefit Plans

 

The Company provides funded and unfunded non-contributory defined benefit pension plans covering certain of its salaried and hourly employees. Benefits are generally based on the employee's age and compensation. The Company funds the plans in an amount not less than the minimum statutory funding requirements or more than the maximum amount that can be deducted for U.S. federal income tax purposes.

 

The Company also currently provides certain postretirement medical and life insurance coverage for eligible employees. Generally, covered employees who terminate employment after meeting eligibility requirements are eligible for postretirement coverage for themselves and their dependents. The salaried employee postretirement benefit plans are contributory, with retiree contributions adjusted annually, and contain other cost-sharing features such as deductibles and coinsurance. The Company's current funding policy is to fund the cost of all postretirement benefits as they are paid.

 

Employees acquired with the ICG acquisition were brought over in their existing plan. Subsequently, the terms of the plan were amended to change vesting periods, coverage caps, and eligible ages, resulting in a reduction of the benefit obligation of $55.5 million.

 

During 2009, the Company notified participants of the retiree medical plan of a plan change increasing the retirees' responsibility for medical costs. This change resulted in a remeasurement of the postretirement benefit obligation, which included a decrease in the discount rate from 6.85% to 5.68%. The remeasurement resulted in a decrease in the liability of $21.0 million, with a corresponding increase to other comprehensive income, and will result in future reductions in costs under the plan.

Pension Benefits

 

The accumulated benefit obligation for all pension plans was $314.7 million and $280.4 million at December 31, 2011 and 2010, respectively. The accumulated benefit obligation differs from the benefit obligation in that it includes no assumption about future compensation levels.

 

The benefit obligation and the accumulated benefit obligation for the Company's unfunded pension plan were $8.2 million and $7.1 million, respectively, at December 31, 2011.

 

The prior service credit and net loss that will be amortized from accumulated other comprehensive income into net periodic benefit cost in 2012 are $0.1 million and $14.3 million, respectively.

 

Other Postretirement Benefits

 

The prior service credit and net gain that will be amortized from accumulated other comprehensive income into net periodic benefit cost in 2012 is $12.0 million and $0.4 million, respectively.

 

 

Components of Net Periodic Benefit Cost.  The following table details the components of pension and other postretirement benefit costs.

The Company establishes the expected long-term rate of return at the beginning of each fiscal year based upon historical returns and projected returns on the underlying mix of invested assets. The Company utilizes modern portfolio theory modeling techniques in the development of its return assumptions. This technique projects rates of return that can be generated through various asset allocations that lie within the risk tolerance set forth by members of the Company's pension committee (the "Pension Committee"). The risk assessment provides a link between a pension's risk capacity, management's willingness to accept investment risk and the asset allocation process, which ultimately leads to the return generated by the invested assets.

 

The health care cost trend rate assumed for 2012 is 7.7% and is expected to reach an ultimate trend rate of 4.5% by 2028. A one-percentage-point increase in the health care cost trend rate would have increased the postretirement benefit obligation at December 31, 2011 by $0.5 million. A one-percentage-point decrease in the health care cost trend rate would have decreased the postretirement benefit obligation at December 31, 2011 by $0.4 million. The effect of these changes would have had an insignificant impact on the net periodic postretirement benefit costs.

 

Plan Assets

 

The Pension Committee is responsible for overseeing the investment of pension plan assets. The Pension Committee is responsible for determining and monitoring appropriate asset allocations and for selecting or replacing investment managers, trustees and custodians. The pension plan's current investment targets are 65% equity, 30% fixed income securities and 5% cash. The Pension Committee reviews the actual asset allocation in light of these targets on a periodic basis and rebalances among investments as necessary. The Pension Committee evaluates the performance of investment managers as compared to the performance of specified benchmarks and peers and monitors the investment managers to ensure adherence to their stated investment style and to the plan's investment guidelines.

 

The Company's pension plan assets at December 31, 2011 and 2010, respectively, are categorized below according to the fair value hierarchy as defined in Note 13, "Fair Values of Financial Instruments":

 

Cash Flows.  In order to achieve a desired funded status, the Company expects to make contributions of $24.5 million to the pension plans in 2012.
