Employee Benefit Plans [Abstract] |
Employee Benefit Plans | Note 14 – Employee Benefit Plans ﻿ The Company has a qualified, defined benefit pension plan that was established to provide benefits to certain employees. The plan is frozen and participants are no longer accruing benefits. Generally, contributions to the plan are not less than the minimum amounts required under the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and not more than the maximum amount that can be deducted for federal income tax purposes. The plan’s assets are held by independent trustees and consist primarily of equity and fixed income securities. ﻿ The Company also historically provided certain postretirement health care benefits for certain of its salaried and hourly retired employees. Generally, employees may become eligible for health care benefits if they retire after attaining specified age and service requirements. These benefits are subject to deductibles, co-payment provisions and other limitations. ﻿ On March 25, 2016, the Company mad e a cash settlement payment of $31,616 (including $166 of interest) to settle disputed retiree medical and life insurance benefits for hourly retirees of the Company’s Johnstown, Pennsylvania manufacturing facility. The settlement resulted in a pre-tax gain of $14,306 (net of plaintiffs’ attorneys’ fees of $1,300) and a reduction in the postretirement benefit obligation of approximately $68,806 as of March 25, 2016. Additionally, as a result of the cost reduction programs initiated in August 2016 and January 2017 (see Note 7), certain employees participating in the salaried pension and postretirement benefit plans were impacted, which triggered curtailment s of the respective plans. ﻿ As of January 1, 2017, the Company changed the method it used to estimate the service and interest components of net periodic benefit cost for postretirement benefits and the interest component for pension benefits. Historically, the Company estimated these service and interest cost components utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. The Company has elected to utilize a full yield curve approach in estimating these components by applying the specific spot rates along the yield curve used in determining the benefit obligation to the relevant projected cash flows. The Company made this change to provide a more precise measurement of service and interest costs by improving the correlation between projected benefit cash flows and the corresponding spot yield curve rates. This change did not affect the measurement of the Company’s total benefit obligation at the Company’s annual measurement date of December 31, 2017, as the refinement compared to the previous method results in a decrease in the service cost and interest components of net periodic benefit cost with an equal offset to actuarial gains (losses) with no net impact on the total benefit obligation. The refinement did not have a material impact on the consolidated balance sheet as of December 31, 2017 or the consolidated statement of operations for the year ended December 31, 2017. This change is accounted for prospectively as a change in accounting estimate. ﻿ ﻿ The changes in benefit obligation, change in plan assets and funde d status as of December 31, 2017 and 2016, are as follows:

﻿ The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid as of December 31, 2017: ﻿ ﻿

﻿ The Company is not required to make any contributions to its pension plan in 2018 to meet its minimum funding requirements. The postretirement benefits in the table above represent benefit payments for the Company’s salaried retirees. ﻿ The assumptions used to determine end of year benefit obligations are shown in the following table: ﻿
﻿ |  |  |  |  |  |  |  |
﻿ |  | Pension Benefits |  | Postretirement Benefits
﻿ |  | 2017 |  | 2016 |  | 2017 |  | 2016
﻿Discount rates |  | 3.68% |  | 4.21% |  | 3.65% |  | 4.21%
﻿ |  |  |  |  |  |  |  |
﻿ ﻿ The discount rate is determined using a yield curve model that uses yields on high quality corporate bonds (AA rated or better) to produce a single equivalent rate. The yield curve model excludes callable bonds except those with make-whole provisions, private placements and bonds with variable rates. ﻿ In October 2017, the Society of Actuaries published updated mortality improvement assumptions for U.S. plans, scale (MP-2017), which reflects additional data that the Social Security Administration has released since prior assumptions (MP-2016) were developed. Scale (MP-2017) results in lower projected mortality improvement than scale (MP-2016). The Company has historically utilized the Society of Actuaries’ published mortality data in its plan assumptions. Accordingly, the Company adopted MP-2017 for purposes of measuring its pension and postretirement obligations at December 31, 2017. ﻿ The assumptions used in the measurement of net periodic cost are shown in the following table: ﻿ ﻿ ﻿ ﻿
﻿ |  |  |  |  |  |  |  |  |  |  |  |
﻿ |  | Pension Benefits |  | Postretirement Benefits
﻿ |  | 2017 |  | 2016 | 2015 |  | 2017 |  | 2016 | 2015
﻿Discount rate for benefit obligations |  | 4.22% |  | 4.47% |  | 4.15% |  | 4.18% |  | 4.39% |  | 4.03%
﻿Expected return on plan assets |  | 5.75% |  | 6.11% |  | 6.24% |  | N/A |  | N/A |  | N/A
﻿Rate for interest on benefit obligations |  | 3.51% |  | N/A |  | N/A |  | 3.48% |  | N/A |  | N/A
﻿Discount rate for service cost |  | N/A |  | N/A |  | N/A |  | 4.55% |  | N/A |  | N/A
﻿ ﻿ As benefits under these postretirement healthcare plans have been capped, assumed health care cost trend rates have no effect on the amounts reported for the health care plans. ﻿ The Company’s pension plan’s weighted average asset allocations at December 31, 2017 and 2016, and target allocations for 2018, by asset category, are as follows: ﻿
﻿ |  |  |  |  |  |
﻿ |  | Plan Assets at December 31, |  | Target Allocation
﻿ |  | 2017 |  | 2016 |  | 2018
﻿Asset Category |  |  |  |  |  |
﻿Cash and cash equivalents |  | 1% |  | 1% |  | 0% - 5%
﻿Equity securities |  | 57% |  | 55% |  | 45% - 65%
﻿Fixed income securities |  | 37% |  | 39% |  | 30% - 50%
﻿Real estate |  | 5% |  | 5% |  | 4%-6%

The basic goal underlying the pension plan investment policy is to ensure that the assets of the plans, along with expected plan sponsor contributions, will be invested in a prudent manner to meet the obligations of the plans as those obligations come due under a broad range of potential economic and financial scenarios, maximize the long-term investment return with an acceptable level of risk based on such obligations, and broadly diversify investments across and within the capital markets to protect asset values against adverse movements in any one market. The Company’s investment strategy balances the requirement to maximize returns using potentially higher return generating assets, such as equity securities, with the need to manage the risk of such investments with less volatile assets, such as fixed-income securities. Investment practices must comply with the requirements of ERISA and any other applicable laws and regulations. The Company, in consultation with its investment advisors, has determined a targeted allocation of invested assets by category and it works with its advisors to reasonably maintain the actual allocation of assets near the target. The long term return on assets was estimated based upon historical market performance, expectations of future market performance for debt and equity securities and the related risks of various allocations between debt and equity securities. Numerous asset classes with differing expected rates of return, return volatility and correlations are utilized to reduce risk through diversification. ﻿ The Company’s pension plan assets are invested in one mutual fund for each fund classification. The following table presents the fair value of pension plan assets classified under the appropriate level of the ASC 820 fair value hierarchy (see Note 2 for a description of the fair value hierarchy) as of December 31, 2017 and 2016: ﻿ ﻿ ﻿ ﻿ ﻿ ﻿

Expenses related to these plans were $1,486, $2,062 and $2,857 for the years ended December 31, 201 7, 201 6 and 201 5, respectively.
