The Company, through its acquisition of Aventine, has assumed a defined benefit pension plan (the “Pension Plan”) and a health care and life insurance plan (the “Postretirement Plan”).

The Pension Plan is noncontributory, and covers unionized employees at the Company’s Pekin, Illinois facility, who fulfill minimum age and service requirements. Benefits are based on a prescribed formula based upon the employee’s years of service. The Pension Plan, part of a collective bargaining agreement, covers only Union employees hired prior to November 1, 2010. The Company uses a December 31 measurement date for its Pension Plan. The Company’s funding policy is to make the minimum annual contributions that are required by applicable regulations. As of December 31, 2015, the Pension Plan’s accumulated projected benefit obligation was $16.6 million, with a fair value of plan assets of $12.6 million. The underfunded amount of $4.0 million is recorded on the Company’s consolidated balance sheet in other noncurrent liabilities. For the three months ended September 30, 2016, the Pension Plan’s net periodic expense was $29,000, comprised of $172,000 in interest cost and $56,000 in service cost, partially offset by $199,000 of expected return on plan assets. For the nine months ended September 30, 2016, the Pension Plan’s net periodic expense was $87,000, comprised of $516,000 in interest cost and $168,000 in service cost, partially offset by $597,000 of expected return on plan assets.

The Postretirement Plan provides postretirement medical benefits and life insurance to certain “grandfathered” unionized employees. Employees hired after December 31, 2000 are not eligible to participate in the Postretirement Plan. The Postretirement Plan is contributory, with contributions required at the same rate as active employees. Benefit eligibility under the plan reduces at age 65 from a defined benefit to a defined collar cap based upon years of service. As of December 31, 2015, the Postretirement Plan’s accumulated projected benefit obligation was $3.6 million and is recorded on the Company’s consolidated balance sheet in other noncurrent liabilities. The Company’s funding policy is to make the minimum annual contributions that are required by applicable regulations. For the three months ended September 30, 2016, the Postretirement Plan’s net periodic expense was $47,000, comprised of $35,000 of interest cost and $12,000 of service cost. For the nine months ended September 30, 2016, the Postretirement Plan’s net periodic expense was $141,000, comprised of $105,000 of interest cost and $36,000 of service cost.
