[1] The zone status represents the most recent available information for the respective MEPP, which may be from 2022 or earlier for the 2023 year and from 2021 or earlier for the 2022 year. In general, plans with a “green” zone status have a funding ratio of at least 80%, plans with an “orange” or “yellow” zone status have a funding ratio of between 65% and less than 80%, and plans with a “red” zone status are less than 65% funded or are projected to have a funding deficiency in any of the next ten years.
[2] This information was obtained from the respective plan’s Form 5500 (“Forms”) for the most current available filing. These dates may not correspond with our fiscal year contributions. The percentages of contributions are based upon disclosures contained in the plans’ Forms. Those Forms, among other things, disclose the names of individual participating employers whose annual contributions account for more than 5% of the aggregate annual amount contributed by all participating employers for a plan year. Accordingly, if the annual contribution of two or more of our subsidiaries each accounted for less than 5% of such contributions, but in the aggregate accounted for in excess of 5% of such contributions, that greater percentage is not available and therefore is not disclosed.
