Summary of Pension Fund

The Company’s participation in this plan for the annual period ended December 31, 2021 is outlined in the table below. The “EIN/Pension Plan Number” column provides the Employee Identification Number (EIN). The zone status is based on information that the Company received from the plan and is certified by the plan’s actuary. Among other factors, plans in the red zone or critical and declining zone are generally less than 65 percent funded, plans in the yellow zone are less than 80 percent funded, and plans in the green zone are at least 80 percent funded. 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. The last column lists the expiration date of the collective-bargaining agreement to which the plan is subject. Finally, the period-to-period comparability of the contributions for 2021 and 2020 was affected by a 4.0% increase in the 2021 contribution rate. There have been no other significant changes that affect the comparability of 2021 and 2020 contributions. The Company does not represent more than 5% of the contributions to this pension fund.
