Notes to Financial Statements |
Pension and Other Postretirement Benefits Disclosure [Text Block] | Note 7 – 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 were $1.9 million for 2017 and $1.6 million in each of the years 2016 and 2015. The Company also sponsors a non-contributory defined benefit postretirement 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 domestic retirees age 65 and over was assumed for 2017 and is expected to remain constant going forward. A 5% rate of increase for all employees under age 65 and Canadian retirees over age 65 was assumed. Plan changes made during 2017 related to prescription drug coverage, spousal coverage and premiums being charged for retirees under age 65 resulted in a decrease in the Accumulated Postretirement Benefit Obligation at year-end. The Company recognizes the obligations associated with its defined benefit pension plan and defined benefit postretirement 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 2017 and 2015, the Company recorded a settlement loss relating to retirees that received lump-sum distributions from the Company’s defined benefit pension plan totaling $4.0 million and $3.8 million, respectively. These charges were the result of lump-sum payments to retirees which exceeded the Plan’s actuarial service and interest cost thresholds. No settlement loss was incurred in 2016. The prior service cost is amortized on a straight-line basis over the average estimated remaining service p eriod 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, in 2014 the Company 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 2017 funding levels, equities may comprise between 7% and 27% of the Plan’s market value. Fixed income investments may comprise between 70% and 90% of the Plan’s market value. Alternative investments may comprise between 0% and 6% 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 a ctive 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 in the following table sets forth by asset class the Plan’s fair value of assets. Plan fair value asset allocation by category:

Contributions The Company expects to contribute $2 million to its defined benefit pension plan in 2018. Expected future benefit payments The following benefit payments are expected to be paid as follows based on actu arial calculations:
|  | 201 8 |  |  | 201 9 |  |  | 20 20 |  |  | 202 1 |  |  | 202 2 |  |  | Thereafter |
Pension |  | $ | 4,274 |  |  | $ | 4,251 |  |  | $ | 5,427 |  |  | $ | 5,046 |  |  | $ | 5,964 |  |  | $ | 26,953 |
Postretirement |  |  | 1,657 |  |  |  | 1,519 |  |  |  | 1,373 |  |  |  | 1,215 |  |  |  | 1,157 |  |  |  | 5,960 |
A one percentage point increase in the assumed health care trend rate would increase postretirement expense by approximately $ 271,000, changing the benefit obligation by approximately $1.6 million; while a one percentage point decrease in the assumed health care trend rate would decrease postretirement health care expense by approximately $233,000, changing the benefit obligation by approximately $1.4 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 5% rate of increase for all employees under age 65 and Canadian retirees over age 65 was assumed. A one percentage point change in the assumed rate of return on the defined benefit pension plan assets is estimated to have an approximate $783,000 effect on pension expense. Additionally, a one percentage point increase in the discount rate is estimated to have a $1.2 million decrease in pension expense, while a one percentage point decrease in the discount rate is estimated to have a $1.4 million increase in pension expense.
