Pension Plans and Other Postretirement Benefits
NOTE 11 - Pension Plans and Other Postretirement Benefits
 
The Company sponsors three qualified and two non-qualified retirement plans. Substantially all employees participate in the 401(k) plan and through December 31, 2014 participated in the non-contributory defined contribution plan. Both the qualified and the non-qualified defined benefit plans have been frozen since 2002. All participants in both frozen plans are 100% vested in their accrued benefit and all non-qualified defined benefit plan participants are receiving payment. 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. Effective January 1, 2015 the Company began matching each dollar of employee contributions up to a 5% maximum — in addition to maintaining the automatic 3% “safe harbor” contribution. The new matching company contribution vests after 5 years of service. The 401(k) plan is fully funded.
 
Prior to 2015, employees participated in a defined contribution plan after one year of service; contributions were made based on eligible earnings and years of service and were credited to each employee’s individual plan account. The majority of employees received a 5% contribution. Accounts vested after 3 years of service. The Company terminated this fully funded defined contribution plan on December 31, 2014 and all participant accounts became 100% vested. The majority of the plan assets were distributed to participants in 2015.
 
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 November 2014, the Company announced a cash-out election period or “window” ending in December 2014, for terminated vested participants with accrued lump sum values under $100. During the window, 385 former employees elected to receive a total of approximately $4,200 in lump sum distributions, resulting in approximately $1,600 of additional settlement expense in 2014.
 
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 all three 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 defined benefit plan were frozen in 2002 and all participants are currently in payment status. Both the non-qualified frozen defined benefit plan 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 qualified and non-qualified defined contribution, 401(k), defined benefit and supplemental retirement plans was $8,899, $11,850 and $10,295 for the years ended December 31, 2015, 2014 and 2013, respectively.

The change in the Company’s AOCI for the defined benefit plans for the year ended December 31, 2015 was primarily attributable to an increase in the discount rate, partially offset by the performance of plan assets. The change in the Company’s AOCI for the defined benefit plans for the year ended December 31, 2014 was primarily attributable to loss recognition in 2014, due to settlement accounting as well as loss amortization included in net periodic benefit cost for 2014. This loss recognition was partially offset by liability losses in 2014 due to a decrease in the discount rate as well as a change in the mortality assumption. The change in the Company’s AOCI for the defined benefit plans for the year ended December 31, 2013 was primarily attributable to the performance of the plan assets and an increase in the discount rate, which was partially offset by a change in the mortality assumption.

The discount rates at December 31, 2015 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.

(1) None of the trust fund assets for the defined benefit pension plan have been invested in shares of HMEC’s common stock.
 
There were no Level 3 assets held during the years ended December 31, 2015 and 2014.
 
In 2016, the Company expects amortization of net losses of $1,351 and $233 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
 
In addition to providing pension benefits, as further described below, prior to 2015 the Company also provided certain health care and life insurance benefits to a closed group of eligible employees (pre-age 65 and former employees). Postretirement benefits other than pensions of active and retired employees were accrued as expense over the employees' service years.
 
As of December 31, 2006, upon discontinuation of retiree medical benefits, Health Reimbursement Accounts (“HRAs”) were established for eligible participants and totaled $7,310. As of December 31, 2015, the balance of the previously established HRAs was $1,896. Funding of HRAs was $523, $252 and $181 for the years ended December 31, 2015, 2014 and 2013, respectively.
 
In December 2013, the Company announced the elimination of postretirement medical coverage for all remaining eligible participants effective March 31, 2014. As a result of this plan change, prior service cost was amortized over the average working lifetime of active eligible participants.
 
In November 2014, the Company announced it would no longer sponsor the retiree group life benefit as of December 2014 and offered a conversion option to individual policies. This was the last remaining postretirement benefit other than pensions.
 
As a result of the changes in the plan for other postretirement benefits, the Company recorded a reduction in its expenses of $2,980 and $196 for the years ended December 31, 2014 and 2013, respectively.
 
The following table presents the funded status of postretirement benefits other than pensions of active and retired employees (including employees on disability more than 2 years) as of December 31, 2014 and 2013 (the measurement dates) reconciled with amounts recognized in the Company's Consolidated Balance Sheets. The tables present postretirement expenses and liabilities only for those years in which the Company incurred expenses or accrued liabilities.
