9. BENEFIT AND RETIREMENT PLANS

Defined Contribution and Retirement Plans

The Company sponsors various defined contribution retirement plans, which cover substantially all employees, other than employees covered by multi-employer pension plans under collective bargaining agreements. Total retirement plan expense was $2.3 million, $1.8 million and $2.0 million in fiscal years 2017, 2016 and 2015, respectively. The amounts include $0.8 million, $0.5 million and $0.5 million in fiscal years 2017, 2016 and 2015, for the Company’s matching contribution to retirement savings plans.

Multi-employer Pension Plans

The Company contributes to three multi-employer defined benefit pension plans under the terms of collective-bargaining agreements that cover its union-represented employees. The risks of participating in these multi-employer plans are different from single-employer plans in the following aspects:

Assets contributed to the multi-employer plan by one employer may be used to provide benefits to employees of other participating employers.

If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be shared by the remaining participating employers.

If a participating employer chooses to stop participating in some of its multi-employer plans, the employer may be required to pay those plans an amount based on the underfunded status of the plan, referred to as a withdrawal liability.

The Company’s participation in these plans for the annual period ended June 30, 2017, is outlined in the following table. Unless otherwise noted, the most recent Pension Protection Act zone status available in 2017 and 2016 is for the plan’s year-end at December 31, 2016 and 2015, respectively. The zone status is based on information that the Company received from the plan and is certified by the plan’s actuary. Among other factors, plans in the red zone are generally less than 65 percent funded, plans in the yellow zone are between 65 percent and 80 percent funded, and plans in the green zone are at least 80 percent funded.

The estimated cumulative cost to exit the Company’s multi-employer plans was approximately $12.3 million on June 30, 2017.

Defined Benefit Plan

The Company’s defined benefit pension plan is frozen. There are a total of 379 participants in the plan. Retirement benefits are based on years of credited service multiplied by a dollar amount negotiated under collective bargaining agreements. The Company’s policy is to fund normal costs and amortization of prior service costs at a level that is equal to or greater than the minimum required under the Employee Retirement Income Security Act of 1974 (ERISA). As of June 30, 2017 and 2016, the Company recorded an accrued benefit liability related to the funded status of the defined benefit pension plan recognized on the Company’s consolidated balance sheets in other long-term liabilities of $0.2 million and $1.6 million, respectively. The accumulated benefit obligation was $8.5 million and $8.9 million at fiscal years ended June 30, 2017 and 2016, respectively. The Company recorded expense of $0.2 million, $0.1 million and $0.1 million during fiscal years 2017, 2016 and 2015, respectively, related to the plan.
