Employee Benefits

7. Employee Benefits

The Company has a defined contribution savings plan covering all regular full-time and part-time employees whereby eligible employees may elect to contribute up to 100% of their annual compensation. The Company matches 100% of an employee's contribution up to the first 4% of such employee's compensation. The Company may, at its discretion, make an additional contribution in an amount as the board of directors may determine. For the years ended December 31, 2011, 2010 and 2009, the Company charged approximately $4,801, $4,556 and $4,450, respectively, to expense for these contributions.

Further, within the defined contribution savings plan, the Company also makes an annual retirement contribution to substantially all employees of one subsidiary and certain employees of another subsidiary who have completed one year of service. The Company's contributions to the plan are determined as a percentage of employees' base and overtime pay. For the years ended December 31, 2011, 2010 and 2009, the Company charged approximately $5,234, $5,209 and $5,173, respectively, to expense for these contributions.

The Company has noncontributory defined benefit pension plans that cover certain eligible salaried and wage employees of one subsidiary. Benefits for salaried employees under these plans are based primarily on years of service and employees' pay near retirement. Benefits for wage employees are based upon years of service and a fixed amount as periodically adjusted. The Company recognizes the years of service prior to the Company's acquisition of the facilities for purposes of determining vesting, eligibility and benefit levels for certain employees of the subsidiary and for determining vesting and eligibility for certain other employees of the subsidiary. The measurement date for these plans is December 31.

The Company also provides post-retirement healthcare benefits to the employees of two subsidiaries who meet certain minimum age and service requirements. The Company has the right to modify or terminate some of these benefits.

Details of the changes in benefit obligations, plan assets and funded status of the Company's pension and post-retirement healthcare plans are as follows:

(1) For 2011, after-tax totals for pension benefits and post-retirement healthcare benefits were $12,873 and $2,270, respectively. The sum of these amounts ($15,143) is reflected in stockholders' equity as accumulated other comprehensive income. For 2010, after-tax totals for pension benefits and post-retirement healthcare benefits were $10,300 and $2,028, respectively. The sum of these amounts ($12,328) is reflected in stockholders' equity as accumulated other comprehensive income.

The Pension Protection Act of 2006 (the "Pension Protection Act") established a relationship between a qualified pension plan's funded status and the actual benefits that can be provided. Restrictions on plan benefits and additional funding and notice requirements are imposed when a plan's funded status is less than certain threshold levels. For the 2011 plan year, the funded status for the Company's pension plans are in the 61% to 80% range. Accordingly, the Company's pension plans are currently restricted from increasing plan benefits, unless the cost of the plan amendment is fully funded by the Company prior to the effective date of the benefit increase. In 2009, the Company amended the pension plan for wage employees to increase, over a three-year period, the monthly benefit multiplier used to compute plan benefits. During 2011, the Company fully funded the benefit increase for the current year prior to the effective date of the benefit increase, so the plan remains in compliance with the Pension Protection Act's benefit restriction requirements.

Pension plans with an accumulated benefit obligation in excess of plan assets at December 31 are as follows:

The estimated prior service cost and net loss for the defined benefit plans that will be amortized from other comprehensive income into net periodic benefit cost during 2012 are expected to be $297 and $1,755, respectively. The estimated prior service cost and net loss for the post-retirement healthcare benefit plans that will be amortized from other comprehensive income into net periodic benefit cost during 2012 are expected to be $84 and $176, respectively. No transition obligation for the post-retirement healthcare benefit plans will be amortized from other comprehensive income into net periodic benefit cost in 2012.

The weighted-average assumptions used to determine pension and post-retirement healthcare plan obligations and net periodic benefit costs for the plans are as follows:

	Pension Benefits									Post-retirement Healthcare
	2011			2010			2009			2011			2010			2009
Weighted average assumptions used to determine benefit obligations at December 31
Discount rate		4.5	%		5.3	%		5.5	%		4.0	%		4.5	%		5.0	%

Rate of compensation increase		4.0	%		4.0	%		4.0	%		—			—			—

The Company's return on asset assumption of 7% is based on historical asset returns, anticipated future performance of the investments and financial markets and input from the Company's third-party independent actuary and the pension fund trustee. The discount rate is determined using a benchmark pension discount curve and applying spot rates from the curve to each year of expected benefit payments to determine the appropriate discount rate for the Company.

Assumed healthcare trend rates do not have a significant effect on the amounts reported for the healthcare plans because benefits for participants are capped at a fixed amount.

The Company's overall investment strategy is to achieve a balance between moderate income generation and capital appreciation. The investment strategy includes a mix of approximately 65% of investments for long-term growth and 35% for near-term benefit payments with a diversification of asset types. The Company does not believe that there are significant concentrations of risk in the pension plan assets due to its strategy of asset diversification. The pension fund investment policy allows the pension fund trustee a 10% discretionary range in the asset allocation model, with a target of approximately 55% equity securities and 45% fixed income. The Company expects to maintain the 55/45 investment policy for the near future. Equity securities primarily include investments in large-cap and small-cap companies located in the United States and international developed market stocks. Fixed income securities are comprised of investment grade bonds, including U.S. Treasuries and corporate bonds of companies from diversified industries.

Under the accounting guidance for fair value measurements, inputs used to measure fair value are classified in one of three levels:

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that are not corroborated by market data.

The investments in the bank collective trust funds are valued using a market approach based on the net asset value of units held. The fair values of the Company's pension plans assets at December 31, by asset category, are as follows:

	2011						2010
	Level 2		Level 3		Total		Level 2		Level 3		Total
Bank collective trust funds—Equity securities:
Large-cap index funds (1)	$	17,562	$	—	$	17,562	$	15,007	$	—	$	15,007
Small-cap index funds (2)		2,324		—		2,324		3,220		—		3,220
International index funds (3)		3,367		—		3,367		3,216		—		3,216
Bank collective trust funds—Fixed income:
Bond index funds (4)		11,806		—		11,806		10,957		—		10,957
Short term investment funds		—		419		419		—		467		467
	$	35,059	$	419	$	35,478	$	32,400	$	467	$	32,867

(1) Over 90% of the assets of these funds are invested in large-cap U.S. companies. The remainder of the assets of these funds is invested in cash reserves.

(2) Over 95% of the assets of these funds are invested in small-cap U.S. companies. The remainder of the assets of these funds is invested in cash reserves.

(3) At least 90% of the assets of these funds are invested in international companies in developed markets (excluding the U.S. and Canada). The remainder of the assets of these funds is invested in cash reserves.

(4) This category represents investment grade bonds of U.S. issuers, including U.S. Treasury notes.

Because of the immaterial amount of the Company's Level 3 pension plans assets, no summary of changes in the fair value of Level 3 pension plans assets is presented.

The Company's funding policy is consistent with the minimum funding requirements of federal law and regulations, and based on preliminary estimates, the Company expects to make contributions of approximately $2,862 for the salaried pension plan and approximately $1,923 for the wage pension plan in 2012.

The following benefit payments are expected to be paid:
