These plans are unfunded and approved claims are paid from Company funds. Historical cash payments made under such plan have typically been less than $100 per year.

Deferred Compensation Plan

On June 1, 2018, the Company established an unfunded, nonqualified deferred compensation plan maintained for the benefit of a select group of management or highly compensated employees.  Assets of the plan are held in a rabbi trust, which are subject to additional risk of loss in the event of bankruptcy or insolvency of the Company.  The deferred compensation liability was $1,642 and $265 as of June 30, 2019 and December 31, 2018, respectively, and is included in other long-term obligations on the Company’s balance sheets. The related rabbi trust assets were $1,642 and $265 as of June 30, 2019 and December 31, 2018, respectively, and are included in other non-current assets on the Company's balance sheets.

Defined Benefit Pension Plans

On May 27, 2019, the Company acquired Chemogas, which had two defined benefit pension plans (DB plans), one of which was closed on December 31, 2018 and replaced by four individual defined contribution plans. The active pension plan is funded by means of employee and Company contributions and provide for the payment of a lump sum at retirement or payments in case of death of the covered employees. The DB plans are considered post-employment benefits. The amount recorded for these obligations on the Company's balance sheets as of June 30, 2019 is $594 and is included in other long-term obligations.
