SUPPLEMENTAL SAVINGS PLAN. Through the 2020 plan year, the Supplemental Savings Plan provides certain senior officers the opportunity to defer receipt of up to 100% of their cash incentive compensation earned for a respective calendar year during which services are provided. The amounts deferred are adjusted in accordance with the hypothetical investments chosen by the officer from a list of mutual funds. Beginning with the plan's 2021 year, the maximum that certain senior officers can defer will be the lesser of 50% of their annual cash incentive earned or $2 million. Additionally, the officers can now defer amounts for a minimum of five years rather than the two years prior to the plan's 2021 year. Previous to the 2021 plan year, the officer could initially defer these amounts for a period of two to 15 years. Certain senior officers elected to defer $63.5 million in 2021, $105.8 million in 2020, and $107.5 million in 2019
