Multiemployer Pension Plans The Company contributes to three multiemployer pension plans. In June 2017, a union contract covering certain of our employees under a multiemployer pension plan expired resulting in a partial withdrawal from one of the multiemployer plans.

Once the multiemployer pension plan's administrators finalize the partial withdrawal liability, it will be paid in equal installments over a twenty year period.
