The change in accrued salaries, benefits and payroll taxes in 2015 and 2014 was attributable to TXI-related severance accrual of $11,444,000 during 2014 and payments of $9,682,000 in 2015. The change in accrued pension, postretirement, and postemployment benefits in 2015 was attributable to higher pension plan funding, which increased $28,270,000. The change in accrued income taxes was primarily attributable to a reduction in the Corporation’s tax liability due to the utilization of net operating loss carryforwards, and the receipt of the federal tax refunds attributable to the settlement of the U.S. Advanced Pricing Agreement.
