Restructuring and Related Activities [Abstract] |
Restructuring Charges | Restructuring Charges At each reporting date, we evaluate our restructuring liabilities, which consist primarily of termination benefits, to ensure that our accruals are still appropriate. In the fourth quarter of 2020, we recognized $38 million of employee severance costs in our restructuring liabilities, which was primarily related to specific targeted actions. During 2019 and 2018, there were no new significant restructuring programs. The following table presents the changes in the position of restructuring liabilities in 2020:

The total restructuring liability as of December 31, 2020 of $74 million is classified in the Consolidated Balance Sheets under current liabilities ($60 million) and non-current liabilities ($14 million).
