Employee Benefit Plans |
| 8. | Employee Benefit Plans
In the fourth quarter of 2014, the Company completed the migration of its retirement benefits from defined-benefit pension plans to defined-contribution retirement plans, utilizing its 401(k) plan. The Company previously sponsored two qualified defined-benefit pension plans that covered substantially all employees. In 2007, the Company amended its hourly and salaried defined-benefit pension plans so that employees no longer accrued benefits under them. This action “froze” the benefits for all employees and prevented future hires from joining the plans. A third defined-benefit pension plan was non-qualified and covered certain executive officers of the Company. The Company sponsors a defined-contribution 401(k) plan that covers substantially all employees. The Company matches employee contributions to their 401(k) accounts using the “safe harbor” guidelines provided in the Internal Revenue Code. In addition, the Company provides discretionary supplemental contributions to substantially all employees' individual 401(k) accounts. Defined-Benefit Plans In December 2014 the Company terminated its defined benefit pension plans and settled all obligations to employees. As a result of the termination of the plans, the Company recognized a one-time charge to expense of $41.0 million in the fourth quarter of 2014, primarily comprised of the recognition of previously deferred actuarial losses. Active employees, all of whom were 100 percent vested in their pension benefits, were given the option of rolling the actuarially determined present value of their benefits into their 401(k) accounts, receiving deferred annuity contracts issued by an insurance carrier, or receiving a lump sum payment. The Company contributed $7.5 million to the frozen pension plans in 2014 in order to fully fund the settlement, representing the shortfall of the existing pension fund assets on the termination date to the settlement value. The Company contributed $3 million and $3 million to these frozen pension plans in 2013 and 2012, respectively, which satisfied the required minimum contribution in each year. Since the plans have been fully funded and settled, no further cash contributions will be required in future years. The measurement dates of the assets and liabilities of all plans presented for 2014 and 2013 were December 31, 2014 and December 31, 2013, respectively. Summarized information on the Company's defined-benefit pension plans is as follows:

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 $3.2 million, $3.0 million, and $2.3 million in 2014, 2013, and 2012, respectively. Additionally, in 2014, 2013, and 2012 the Company provided discretionary supplemental 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 $5.6 million, $4.9 million, and $3.3 million in 2014, 2013, and 2012, respectively.
