OTHER EMPLOYEE BENEFIT PLANS:

UMWA Benefit Trusts

The Coal Act created two multi-employer benefit plans: (1) the United Mine Workers of America Combined Benefit Fund (the “Combined Fund”) into which the former UMWA Benefit Trusts were merged, and (2) the United Mine Workers of America 1992 Benefit Plan (the “1992 Benefit Plan”). CONSOL Energy accounts for required contributions to these multi-employer trusts as expense when incurred.

The Combined Fund provides medical and death benefits for all beneficiaries of the former UMWA Benefit Trusts who were actually receiving benefits as of July 20, 1992. The 1992 Benefit Plan provides medical and death benefits to orphan UMWA-represented members eligible for retirement on February 1, 1993, and for those who retired between July 20, 1992 and September 30, 1994. The Coal Act provides for the assignment of beneficiaries to former employers and the allocation of unassigned beneficiaries (referred to as orphans) to companies using a formula set forth in the Coal Act. The Coal Act requires that responsibility for funding the benefits to be paid to beneficiaries be assigned to their former signatory employers or related companies. This cost is recognized when contributions are assessed. CONSOL Energy's total contributions under the Coal Act were $7,647, $8,455 and $9,239 for the years ended December 31, 2017, 2016 and 2015, respectively. Based on available information at December 31, 2017, CONSOL Energy's obligation for the Combined Fund and 1992 Benefit Plans is estimated to be approximately $82,501.

Pursuant to the provisions of the Tax Relief and Healthcare Act of 2006 (the “2006 Act”) and the 1992 Benefit Plan, CONSOL Energy is required to provide security in an amount based on the annual cost of providing health care benefits for all individuals receiving benefits from the 1992 Benefit Plan who are attributable to CONSOL Energy, plus all individuals receiving benefits from an individual employer plan maintained by CONSOL Energy who are entitled to receive such benefits. In accordance with the terms of the 2006 Act and the 1992 Benefit Plan, CONSOL Energy must secure its obligations by posting letters of credit, which were $20,983, $19,170 and $21,473 at December 31, 2017, 2016 and 2015, respectively. The 2017, 2016 and 2015 security amounts were based on the annual cost of providing health care benefits and included a reduction in the number of eligible employees.

Investment Plan

CONSOL Energy has an investment plan available to most non-represented employees. Eligible employees of Consol Pennsylvania Coal Company began participation in the Consol Pennsylvania Coal Company Investment Plan (the “CPCC 401(k) plan”) on September 1, 2017, which was the inception date of the CPCC 401(k) plan. Remaining eligible employees of CONSOL Energy began participation in the CPCC 401(k) plan on November 1, 2017. Prior to participating in the CPCC 401(k) plan, eligible employees of CONSOL Energy participated in CONSOL Energy’s, now known as CNX Resources Corporation, 401(k) plan. Both the CNX and the CPCC 401(k) plans include Company matching of 6% of eligible compensation contributed by eligible employees of CONSOL Energy. In conjunction with the qualified pension plan changes in 2015, the Company contributed an additional 3% of eligible compensation into the 401(k) plan accounts for employees hired or rehired on or after October 1, 2014 or who were under age 40 or had less than 10 years of service with the Company as of September 30, 2014. This additional contribution was eliminated on January 1, 2016. The Company may also make discretionary contributions to the Plan ranging from 1% to 6% (1% to 4% prior to January 1, 2016) of eligible compensation for eligible employees (as defined by the Plan). There were no such discretionary contributions made by the Company for the years ended December 31, 2017 and 2015. Discretionary contributions made by the Company were $9,499 for the year ended December 31, 2016. Total payments and costs were $9,888, $17,687 and $13,729 for the years ended December 31, 2017, 2016 and 2015, respectively.
