(1)The most recent PPA zone status available in 2024 and 2023 is for the plan’s year-end during 2023 and 2022, respectively. The zone status is based on information that we received from the plan and is certified by the plan’s actuary. Among other factors, plans in the red zone are generally less than 65 percent funded, plans in the orange zone are less than 80 percent funded and have an Accumulated Funding Deficiency in the current year or projected into the next six years, plans in the yellow zone are less than 80 percent funded, and plans in the green zone are at least 80 percent funded. (2)The “FIP/RP Status Pending/Implemented” column indicates plans for which a financial improvement plan (“FIP”) or a rehabilitation plan (“RP”) is either pending or has been implemented. (3)Lists the expiration date(s) of the collective-bargaining agreement(s) to which the plans are subject. Pension trust funds with a range of expiration dates have various collective bargaining agreements.
