Restructuring

21. Restructuring

During the years ended December 31, 2021, 2020 and 2019, the Company incurred restructuring (income) expense of $(1.1) million, $7.0 million and $9.8 million, respectively. Restructuring income for 2021 primarily related to adjustments of previously recorded costs associated with a lease write-off in the Americas and headcount reductions in Europe. In addition, the Company recorded income on the sale of previously expensed Brazilian tax credits. Expenses for 2020 related primarily to costs associated with headcount reductions in Europe and North America, partially offset by $2.5 million of income primarily related to the forfeiture of equity compensation awards associated with employee separation agreements. The costs for 2019 related primarily to severance costs for headcount reductions in Europe, North America and India. Restructuring expense for the years ended December 31, 2021, 2020 and 2019 included zero, $2.2 million, and zero, respectively, of expense related to executive severance.

The following is a summary of the Company's restructuring activities for the years ended December 31, 2021, 2020 and 2019:
