[1] The amount of share-based compensation recognized in 2021 associated with liability awards includes 0.2 million of performance share units held by five employees that are scheduled to vest in 2022 that were reclassified from equity awards to liability awards during 2021 as a result of a modification to settle the awards in cash in lieu of shares. We recognized approximately $18 million in incremental expense as a result of the modification.
