(1) The Pension Protection Act of 2006 ranks the funded status of multi-employer pension plans depending upon a plan's current and projected funding. A plan is in the Red Zone (Critical) if it has a current funded percentage of less than 65.0%. A plan is in the Yellow Zone (Endangered) if it has a current funded percentage of less than 80.0%, or projects a credit balance deficit within seven years. A plan is in the Green Zone (Healthy) if it has a current funded percentage greater than 80.0% and does not have a projected credit balance deficit within seven years. The zone status is based on the plan’s year end rather than the Company's. The zone status listed for each plan is based on information that the Company received from that plan and is certified by that plan’s actuary for the most recent year available. (2) Funding Improvement Plan or Rehabilitation Plan as defined in the Employee Retirement Income Security Act of 1974 has been implemented or is pending. (3) Indicates whether the Company paid a surcharge to the plan in the most current year due to funding shortfalls and the amount of the surcharge. (4) The Company represented more than 5.0% of the total contributions for the most recent plan year available. For year ended December 31, 2018, the Company contributed $0.7 million to the plan.
