*Not applicable

(1) To determine individually significant plans, we evaluated several factors, including our total contributions to the plan, our significance to the plan in terms of participating employees and contributions, and the funded status of the plan.

(2) The “EIN/PN” column provides the Employer Identification Number and the three-digit plan number assigned to the plan by the IRS.

(3) The Pension Protection Act Zone Status columns provide the two most recently available Pension Protection Act zone statuses from each plan. The zone status is based on information provided to us and other participating employers and is certified by each plan’s actuary. Among other factors, plans in the red zone are generally less than 65% funded, plans in the yellow zone are less than 80% funded, and plans in the green zone are at least 80% funded.

(4) Indicates whether a Financial Improvement Plan (“FIP”) for yellow zone plans or a Rehabilitation Plan (“RP”) for red zone plans is pending or implemented.

(5) Indicates whether our contribution in 2022 included an amount as imposed by a plan in the red zone in addition to the contribution rate specified in the applicable collective bargaining agreement.
