Note 10: Benefit Plans

We sponsor three funded, noncontributory defined benefit pension plans. These plans cover substantially all employees hired prior to July 15, 2007, other than those covered by union-administered plans. Benefits for the Salaried Plan are generally based on salaries or wages and years of service; the Construction Materials Hourly Plan and the Chemicals Hourly Plan provide benefits equal to a flat dollar amount for each year of service. In addition to these qualified plans, we sponsor three unfunded, nonqualified pension plans. Effective July 15, 2007, we amended our defined benefit pension plans to no longer accept new participants. In May 2013, we announced that future accruals for salaried pension participants will cease effective December 31, 2013. This change included a special transition provision which will allow salaries or wages through December 31, 2015 to be considered in the participants’ benefit calculations. The announcement resulted in a curtailment and remeasurement of the salaried and nonqualified pension plans as of May 31, 2013 that will reduce our 2013 pension expense by approximately $7,600,000 (net of the one-time curtailment loss noted below) of which $800,000 relates to discontinued operations. See Note 11 for the impact of this remeasurement to our pension plan funded status. The following table sets forth the components of net periodic pension benefit cost:

In addition to pension benefits, we provide certain healthcare and life insurance benefits for some retired employees. In the fourth quarter of 2012, we amended our postretirement healthcare plan to cap our portion of the medical coverage cost at the 2015 level. Effective July 15, 2007, we amended our salaried postretirement healthcare coverage to increase the eligibility age for early retirement coverage to age 62, unless certain grandfathering provisions were met. Substantially all our salaried employees and where applicable, hourly employees may become eligible for these benefits if they reach a qualifying age and meet certain service requirements. Generally, Company-provided healthcare benefits terminate when covered individuals become eligible for Medicare benefits, become eligible for other group insurance coverage or reach age 65, whichever occurs first. The following table sets forth the components of net periodic postretirement benefit cost:



OTHER POSTRETIREMENT BENEFITS	Three Months Ended		Six Months Ended

The reclassifications from AOCI noted in the tables above are related to curtailment losses, amortization of prior service costs or credits and actuarial losses as shown in Note 11.

Prior contributions, along with the existing funding credits, are sufficient to cover required contributions to the qualified plans through 2013.
