Schedule of Health Care Cost Trend Rates [Table Text Block] | The assumed health care cost trend rate for other postretirement benefits for pre-age 65 benefits as of December 31 was as follows:
| Pre-age 65 Benefits
| 2019 |  | 2018
Health care cost trend rate for next year | 5.4 | % |  | 5.5 | %
Rate to which the cost trend rate is assumed to decline (the ultimate trend rate) | 4.5 | % |  | 4.5 | %
Year rate reaches the ultimate trend rate | 2037 |  |  | 2037 |
Effect of One-Percentage-Point Change in Assumed Health Care Cost Trend Rates | A one percent change in the assumed health care trend rate at December 31, 2019 would not have a material impact on the accumulated postretirement benefit obligation.
Weighted-Average Assumptions Used to Determine Benefit Obligations and Net Pension and Other Postretirement Benefit Costs | Weighted average assumptions used to determine pension and other postretirement benefit obligations at December 31 were as follows:
| Pension Benefits |  | Other Postretirement Benefits
| 2019 |  | 2018 |  | 2019 |  | 2018
Discount rate | 2.96 | % |  | 4.13 | % |  | 3.07 | % |  | 4.20 | %
Weighted average assumptions used to determine net pension and other postretirement benefit costs for the years ended December 31 were as follows:
| 2019 |  | 2018 |  | 2017
Discount rate for pension benefits (A) (B) | 4.13% |  | 3.27% |  | 3.40%
Discount rate for other postretirement benefits (A) (B) | 3.85% |  | 3.08% |  | 3.17%
Long-term rate of return on plan assets (C) | NA |  | 4.25% |  | 4.75%
(A) The Company utilizes a yield curve analysis to calculate the discount rates used to determine pension and other postretirement benefit obligations. The yield curve analysis matches the cash flows of the Company's benefit obligations. The yield curve consisted of spot interest rates at half year increments for each of the next 30 years and was developed based on pricing and yield information for high quality corporate bonds rated Aa by either Moody's or Standard & Poor's, private placement bonds that are traded in reliance with Rule 144A and are at least two years from date of issuance, bonds with make-whole provisions and bonds issued by foreign corporations that are denominated in U.S. dollars, excluding callable bonds and bonds less than a minimum size and other filtering criteria. Additionally, the Company's yield curve methodology includes bonds having a yield that is greater than the regression mean yield curve as the Company believes this methodology represents an appropriate estimate of the rates at which the Company could effectively settle its pension obligations. For the Company's Salaried and Bargaining plans which were terminated during 2018, the discount rate was a blend of the December 31, 2018 yield curve rate associated with those participants electing annuity contracts to cover future benefit payments, and a lump-sum segment rate for those participants electing lump-sum benefit payments. (B) The Company uses a "spot rate approach" in the calculation of pension and postretirement interest costs to provide a more accurate measurement of interest costs. The spot rate approach applies separate discount rates for each projected benefit payment in the calculation of pension and postretirement interest costs. (C) The Company evaluates its assumption regarding the estimated long-term rate of return on plan assets based on historical experience, future expectations of investment returns, asset allocations, investment strategies and views of investment professionals.

(A) | See Note 7 – Fair Value Measurements for a description of levels within the fair value hierarchy. The level in the fair value hierarchy within which the fair value measurement is classified is determined based on the lowest level input that is significant to the fair value measurement in its entirety. A description of the valuation methodologies is provided following these tables. There were no transfers in and/or out of Level 1 and Level 2 in 2018.
(B) | The equity assets are invested in two indexed funds based on the Russell 3000 Index (U.S.) and the MSCI EAFE Equity Index (International). The Trust did not directly own any of the Company's common stock as of December 31, 2018.
