Pension and Other Postretirement Benefits Disclosure [Text Block] | Note G – Pensions and Other Postretirement Benefits The Company sponsors a defined benefit pension plan (“Plan”) covering certain domestic employees. Benefits are based on each covered employee’s years of service and compensation. The Plan is funded in conformity with the funding requirements of applicable U.S. regulations. The Plan was closed to new participants effective January 1, 2008. Employees hired after this date, in eligible locations, participate in an enhanced 401(k) plan instead of the defined benefit pension plan. Employees hired prior to this date continue to accrue benefits. Additionally, the Company sponsors defined contribution pension plans made available to all domestic and Canadian employees. Total contributions to the plans in 2015 and 2014 were $1.6 million and were $1.3 million in 2013. The Company also sponsors a non-contributory defined benefit health care plan that provides health benefits to certain domestic and Canadian retirees and their spouses. The Company funds the cost of these benefits as incurred. For measurement purposes, and based on maximum benefits as defined by the plan, a zero percent annual rate of increase in the per capita cost of covered health care benefits for retirees age 65 and over was assumed for 2015 and is expected to remain constant going forward. A 5% rate of increase for retirees under age 65 was assumed. The Company recognizes the obligations associated with its defined benefit pension plan and defined benefit health care plan in its consolidated financial statements. The following table presents the plans’ funded status as of the measurement date reconciled with amounts recognized in the Company’s consolidated balance sheets:

During 2015 and 2013, the Company recorded settlement losses relating to retirees that received lump-sum distributions from the Company’s defined benefit pension plan totaling $3.8 million and $4.2 million, respectively. These charges were the result of lump-sum payments to retirees which exceeded the Plan’s actuarial service and interest cost thresholds in each of 2015 and 2013. The cost threshold was not exceeded in 2014. The prior service cost is amortized on a straight-line basis over the average estimated remaining service period of active participants. The unrecognized actuarial gain or loss in excess of the greater of 10% of the benefit obligation or the market value of plan assets is also amortized on a straight-line basis over the average estimated remaining service period of active participants.

To enhance the Company’s efforts to mitigate the impact of the defined benefit pension plan on its financial statements, the Company has recently moved towards a liability driven investing model to more closely align assets with liabilities based on when the liabilities are expected to come due. Currently, based on 2015 funding levels, equities may comprise between 14% and 34% of the Plan’s market value. Fixed income investments may comprise between 60% and 80% of the Plan’s market value. Alternative investments may comprise between 0% and 12% of the Plan’s market value. Cash and cash equivalents (including all senior debt securities with less than one year to maturity) may comprise between 0% and 10% of the Plan’s market value. Financial instruments included in pension plan assets are categorized into a fair value hierarchy of three levels, based on the degree of subjectivity inherent in the valuation methodology. Level 1 assets are based on unadjusted quoted prices in active markets that are accessible to the reporting entity at the measurement date for identical assets. Level 2 assets are valued at inputs other than quoted prices in active markets for identical assets that are observable either directly or indirectly for substantially the full term of the assets. Level 3 assets are valued based on unobservable inputs for the asset (i.e., supported by little or no market activity).These inputs include management’s own assessments about the assumptions that market participants would use in pricing assets (including assumptions about risk).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 measure in its entirety. All of the Plan’s assets are in level 1 or level 2 within the fair value hierarchy and the following table sets forth by asset class the Plan’s fair value of assets.

Contributions The Company may contribute $2 million to $6 million to its pension plan in 2016. Expected futu r e benefit p a yments The following benefit payments are expected to be paid as follows based on actuarial calculations:
|  | 2016 |  |  | 2017 |  |  | 2018 |  |  | 2019 |  |  | 2020 |  |  | Thereafter |
Pension |  | $ | 5,524 |  |  | $ | 7,498 |  |  | $ | 7,544 |  |  | $ | 6,055 |  |  | $ | 7,205 |  |  | $ | 29,274 |
Postretirement |  |  | 1,678 |  |  |  | 1,677 |  |  |  | 1,651 |  |  |  | 1,656 |  |  |  | 1,666 |  |  |  | 8,757 |
A one percentage point increase in the assumed health care trend rate would increase postretirement expense by approximately $274,000, changing the benefit obligation by approximately $2.1 million; while a one percentage point decrease in the assumed health care trend rate would decrease postretirement expense by approximately $232,000, changing the benefit obligation by approximately $1.8 million. The assumed trend rates for healthcare costs are a 5% increase per year for retirees prior to the age 65 and 0% for retirees post age 65. A one percentage point change in the assumed rate of return on the defined benefit pension plan assets is estimated to have an approximate $677,000 effect on pension expense. Additionally, a one percentage point increase in the discount rate is estimated to have a $1.6 million decrease in pension expense, while a one percentage point decrease in the discount rate is estimated to have a $1.9 million increase in pension expense.
