Retirement Benefits [Text Block] | 18. Pension and Postretirement Benefits: We have a frozen qualified defined benefit pension plan for certain of our employees through membership in the Pension Plan for Insurance Organizations (the “Pension Plan”), a multiple-employer trust. Prior to the freeze, we applied a cash balance formula to determine future benefits. Under the cash balance formula, each participant has an account, which was credited annually based on salary rates determined by years of service, as well as the interest earned on the previous year-end cash balance. We also have a non-qualified frozen supplemental cash balance plan (“SERP”) for certain employees. Our SERP is funded from our general assets. Our Pension Plan’s funding policy is to contribute annually at an amount between the minimum funding requirements set forth in the Employee Retirement Income Security Act of 1974 and the maximum amount that can be deducted for federal income tax purposes. The minimum contribution requirement was and is expected to be $0 in 2020 and 2021, respectively. We contributed $0.7 million to our SERP in 2020 and 2019, and expect to contribute $1.0 million in 2021. We also provide certain healthcare and life insurance benefits for both active and retired employees. The Postretirement Health and Life Insurance Plan (the “Postretirement Plan”), which has been frozen, is contributory, requiring participants to pay a stated percentage of the premium for coverage. We do not expect to contribute to our Postretirement Plan in 2021. The following table sets forth the changes in the benefit obligations and the plan assets, the funded status of the Pension Plan, SERP and Postretirement Plan, and the amounts recognized in our consolidated balance sheets at December 31:

The healthcare cost trend rate for 2021 was 8.00% gradually decreasing to 4.50% in 2035. Assumed healthcare cost trend rates have a significant effect on the amounts reported for the healthcare plan. However, a 1.00% change in assumed healthcare cost trend rates would have an immaterial effect to our postretirement benefit obligation. The subsidy benefit from the Medicare Prescription Drug, Improvement and Modernization Act of 2003 reduced our accumulated postretirement benefit assets by approximately $0.8 million as of December 31, 2020 and 2019. The subsidy cost increased the net periodic benefit cost by approximately $58.2 thousand, $48.5 thousand and $51.0 thousand in fiscal 2020, 2019 and 2018, respectively. The expected return on our Pension Plan assets as of December 31, 2020 and 2019 was 6.50% and 6.75%, respectively, which was determined by taking into consideration our analysis of our actual historical investment returns to a broader long-term forecast after adjusting for the target investment allocation and reflecting the current economic environment. During the first quarter of 2020, we changed the investment guidelines on our Pension Plan assets to target investment allocation of 55% to equity securities and 45% to debt securities from our previous target allocation of 60% to equity securities and 40% to debt securities as of December 31, 2019. Our Pension Plan assets consist primarily of investments in various fixed income and equity funds. Investment guidelines are established with each investment manager. These guidelines provide the parameters within which the investment managers agree to operate, including criteria that determine eligible and ineligible securities, diversification requirements and credit quality standards, where applicable. Investment managers are prohibited from entering into any speculative hedging transactions. The investment objective is to achieve a maximum total return with strong emphasis on preservation of capital in real terms. As of December 31, 2020 and 2019, the domestic equity portion of the total portfolio ranged between 40% and 60%. The international equity portion of the total portfolio ranged between 10% and 20%. The fixed income portion of the total portfolio ranged between 20% and 40%. The asset allocation at December 31, 2020 and 2019, and target allocation by asset category are as follows:
|  | Target |  |  | Percentage of Plan Assets |
Asset Category |  | Allocation |  |  | 2020 |  |  | 2019 |
Equity securities |  |  | 55.0 | % |  |  | 52.5 | % |  |  | 53.7 | %
Debt securities |  |  | 45.0 | % |  |  | 40.0 | % |  |  | 37.9 | %
Other |  |  | — | % |  |  | 7.5 | % |  |  | 8.4 | %
Total |  |  | 100.0 | % |  |  | 100.0 | % |  |  | 100.0 | %
We have used the target investment allocation to derive the expected return as we believe this allocation will be retained on an ongoing basis that will be commensurate with the projected cash flows of the plan. The expected return for each investment category within the target investment allocation is developed using average historical rates of return for each targeted investment category, considering the projected cash flow of our Pension Plan. The difference between this expected return and the actual return on plan assets is generally deferred and recognized over subsequent periods through future net periodic benefit costs. We believe that the use of the average historical rates of returns is consistent with the timing and amounts of expected contributions to the plans and benefit payments to plan participants. These considerations provide the basis for reasonable assumptions with respect to the expected long-term rate of return on plan assets. We also maintain a voluntary employees beneficiary association plan (the “VEBA Plan”) under Section 501(c)(9) of the Internal Revenue Code to fund the Postretirement Plan. The asset allocation for our VEBA Plan at December 31, 2020 and 2019 was 100% in debt securities. There were no transfers among Levels 1, 2 or 3 for the years ended December 31, 2020 and 2019. Refer to Note 7. Fair Value Measurements for further discussion with respect to fair value hierarchy. The following table summarizes the fair value measurements by level of our Pension Plan and Postretirement Plan assets:

(2) | The pooled separate accounts invest in domestic and foreign stocks, bonds and mutual funds. The fair values of these stocks, bonds and mutual funds are publicly quoted and are used in determining the NAV of the pooled separate account, which is not publicly quoted.
(3) | Investments for which readily determinable prices do not exist are valued by the General Partner using either the market or income approach. In establishing the estimated fair value of investments, including those without readily determinable values, the General Partner assumes a reasonable period of time for liquidation of the investment, and takes into consideration the financial condition and operating results of the underlying portfolio company, nature of investment, restrictions on marketability, holding period, market conditions, foreign currency exposures, and other factors the General Partner deems appropriate.
