Employee Benefit Plans [Abstract] |
Employee Benefit Plans |
| 8. | Employee Benefit Plans
The Company has migrated its retirement benefits from defined-benefit pension plans to defined-contribution retirement plans, utilizing its current 401(k) plan. The Company sponsored two qualified defined-benefit pension plans that covered substantially all employees. A third defined-benefit pension plan is non-qualified and covered certain executive officers of the Company. The Company also sponsors a defined-contribution 401(k) plan that covers substantially all employees. Defined-Benefit Plans In 2007, the Company amended its hourly and salaried defined-benefit pension plans so that employees no longer accrued benefits under them after December 31, 2007. This action "froze" the benefits for all employees and prevented future hires from joining the plans, effective December 31, 2007. Currently, the Company provides supplemental discretionary contributions to substantially all employees' individual 401(k) accounts. Minimum contributions of $2.6 million were required for the defined-benefit plans for 2012. The Company contributed $3 million and $2 million in 2012 and 2011, respectively. In future years, the Company may again be required to make cash contributions to the two defined-benefit pension plans. The annual contributions will be based on the amount of the unfunded plan liabilities derived from the frozen benefits and will not include liabilities for any future accrued benefits for any new or existing participants. The total amount of these future cash contributions will depend on the investment returns generated by the plans' assets and the then-applicable discount rates used to calculate the plans' liabilities. The Company plans to contribute approximately $3 million in 2013, but will increase the amount of the contribution if required to do so. The intent of these contributions is to reduce the amount of time that the Company will be required to continue to operate the frozen plans. The ongoing cost of running the plans (even if frozen) is approximately $0.4 million per year, which includes PBGC premiums, actuary and audit fees, and other expenses. The measurement dates of the assets and liabilities of all plans presented for 2012 and 2011 were December 31, 2012 and December 31, 2011, respectively. Summarized information on the Company's defined-benefit pension plans is as follows:

The estimated future benefit payments for the defined-benefit plans for each of the next five years and the total amount for years six through ten, are as follows: 2013-$3.4 million, 2014-$3.6 million, 2015-$3.8 million, 2016-$4.0 million, 2017-$4.1 million and for the five year period ending 2021-$22.7 million. The Company determines the expected return on plan assets based on the target asset allocations. In addition, the historical returns of the plan assets are also considered in arriving at the expected rate of return. The Company recorded an additional minimum pension liability adjustment, net of tax, which decreased comprehensive income by $2.1 million and $7.9 million in 2012 and 2011 and increased comprehensive income by $0.7 million in 2010, respectively. Plan Assets The current investment objective is to produce income and long-term appreciation through a target asset allocation of 35% debt securities and other fixed income investments including cash and short-term instruments, and 65% equity investments, to provide for the current and future benefit payments of the plans. The pension plans are not invested in the common stock of the Company. The Company adopted the provisions of the Financial Accounting Standard Board's Accounting Standards Codification 821.10 ("ASC 820.10") which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. The Company has determined that all financial assets of both its defined-benefit pension plans are level 2 in the fair value hierarchy established by ASC 820.10. The valuation of level 2 assets are based on inputs, other than quoted prices in active markets, that are either directly or indirectly observable for the assets. The disclosures focus on the inputs used to measure fair value. The following is a description of the valuation methodologies used to measure the plans' assets at fair value: Pooled separate accounts: Valued at the net asset value ("NAV") of units held by the plans at year end, which is determined by aggregating the quoted market values of the underlying assets. Money market funds: Valued at the NAV of shares held by the plans at year end, which is generally intended to equal one dollar per share. The following table sets forth the defined-benefit plans' assets at fair value:

Defined-Contribution Plans Prior to 2007, the Company also sponsored two qualified defined-contribution plans that covered substantially all of its hourly and salaried employees. Effective January 1, 2007, the qualified defined-contribution plans were merged into a single 401(k) plan. Under the terms of the 401(k) plan, the Company matches a certain portion of employee contributions. Expenses related to matching employee contributions to the 401(k) plan were $2.3 million, $2.0 million, and $1.8 million in 2012, 2011, and 2010, respectively. Additionally, in 2012, 2011, and 2010 the Company provided supplemental discretionary contributions to the individual 401(k) accounts of substantially all employees. Each employee received a supplemental contribution to their account based on a uniform percentage of qualifying compensation established annually. The cost of these supplemental contributions totaled $3.3 million, $2.1 million, and $1.8 million in 2012, 2011, and 2010, respectively. Non-Qualified Plan The Company also sponsors a non-qualified defined-contribution plan, the Supplemental Executive Retirement Plan, which covered certain of its salaried employees. Only one participant, who is retired, remains in this plan.
