Pension Plans and Other Postretirement Benefits | The Company sponsors two qualified and three non-qualified retirement plans. Substantially all employees participate in the 401(k) plan. Both the qualified defined benefit plan and the two non-qualified supplemental defined benefit plans have been frozen since 2002. All participants in the frozen plans are 100% vested in their accrued benefit and all non-qualified supplemental defined benefit plan participants are receiving payments. Certain employees participate in a non-qualified defined contribution plan. Qualified Plans All employees participate in the 401(k) plan and receive a 100% vested 3% "safe harbor" company contribution based on employees' eligible earnings. The Company matches each dollar of employee contributions up to a 5% maximum — in addition to maintaining the automatic 3% "safe harbor" contribution. The matching company contribution vests after 5 years of service. The 401(k) plan is fully funded. In 2002, participants ceased accruing benefits for earnings and years of service in the frozen defined benefit plan. A substantial number of those participants are former employees of the Company who are not eligible to receive an immediate annuity benefit until age 65 and/or are not eligible for a lump sum distribution. In August of 2016, the Company announced a cash-out election "window" ending in September 2016 for all vested terminated participants. During this window, 52 former employees elected to receive a total of approximately $1,400 thousand in lump sum distributions. The Company's policy for the frozen defined benefit plan is to contribute to the plan amounts which are actuarially determined to provide sufficient funding to meet future benefit payments as defined by federal laws and regulations. For the two qualified plans, all assets are held in their respective plan trusts. Non-qualified Plans The non-qualified plans were established for specific employees whose otherwise eligible earnings exceeded the statutory limits under the qualified plans. Benefit accruals under the non-qualified supplemental defined benefit plans were frozen in 2002 and all participants are currently in payment status. Both the non-qualified frozen supplemental defined benefit plans and the non-qualified contribution plan are unfunded plans with the Company's contributions made at the time payments are made to participants. Total Expense and Contribution Plans' Information Total expense recorded for the non-qualified defined contribution, 401(k), defined benefit and supplemental retirement plans was $8,851 thousand, $9,114 thousand and $8,527 thousand for the years ended December 31, 2018, 2017 and 2016, respectively. Contributions to employees' accounts under the 401(k) plan and the non-qualified defined contribution plan, as well as total assets of the plans, were as follows:
Defined Benefit Plan and Supplemental Retirement Plans The following tables summarize the funded status of the defined benefit and supplemental retirement pension plans as of December 31, 2018, 2017 and 2016 (the measurement dates) and identify (1) the assumptions used to determine the projected benefit obligation and (2) the components of net pension cost for the defined benefit plan and supplemental retirement plans for the following periods:
The change in the Company's AOCI for the defined benefit plans for the year ended December 31, 2018 was primarily attributable to lower than expected asset returns and updates to mortality assumptions and an increase in the discount rate. The change in the Company's AOCI for the defined benefit plans for the year ended December 31, 2017 was primarily attributable to better than expected asset returns and updates to mortality assumptions partially offset by a decrease in the discount rate. The change in the Company's AOCI for the defined benefit plans for the year ended December 31, 2016 was primarily attributable to a decrease in the discount rate, partially offset by the performance of plan assets.
____________________ * Not applicable. The discount rates at December 31, 2018 were based on the average yield for long-term, high-grade securities available during the benefit payout period. To set its discount rate, the Company looks to leading indicators, including the Mercer Above Mean Yield Curve. The assumption for the long-term rate of return on plan assets was determined by considering actual investment experience during the lifetime of the plan, balanced with reasonable expectations of future growth considering the various classes of assets and percentage allocation for each asset class. The Company has an investment policy for the defined benefit pension plan that aligns the assets within the plan's trust to an approximate allocation of 50% equity and 50% fixed income funds. Management believes this allocation will produce the targeted long-term rate of return on assets necessary for payment of future benefit obligations, while providing adequate liquidity for payments to current beneficiaries. Assets are reviewed against the defined benefit pension plan's investment policy and the trustee has been directed to adjust invested assets at least quarterly to maintain the target allocation percentages. Fair values of the equity security funds and fixed income funds have been determined from public quotations. The following table presents the fair value hierarchy for the Company's defined benefit pension plan assets, excluding cash held.
____________________
There were no Level 3 assets held during the years ended December 31, 2018 and 2017. In 2019, the Company expects amortization of net losses of $310 thousand and $256 thousand for the defined benefit plan and the supplemental retirement plans, respectively, and expects no amortization of prior service cost for the supplemental retirement plans to be included in net periodic pension expense. Postretirement Benefits Other than Pensions As of December 31, 2006, upon discontinuation of retiree medical benefits, Health Reimbursement Accounts (HRAs) were established for eligible participants and totaled $7,310 thousand. As of December 31, 2018, the balance of the previously established HRAs was $1,438 thousand. Funding of HRAs was $88 thousand, $133 thousand and $218 thousand for the years ended December 31, 2018, 2017 and 2016, respectively. 2019 Contributions In 2019, there is no minimum funding requirement for the Company's defined benefit plan. The following table discloses that minimum funding requirement and the expected full year contributions for the Company's plans.

Estimated Future Benefit Payments The Company's defined benefit plan may be subject to settlement accounting.

Therefore, actual results could vary from the estimates shown. Estimated future benefit payments as of December 31, 2018 were as follows:
