[1] ROU asset amounts are a component of “Other assets” on our Consolidated Balance Sheet.

[2] At December 31, 2023, lease liabilities of $75 million and $323 million were included within “Other current liabilities” and “Other long-term liabilities,” respectively.

[3] The discount rate for each category of assets represents the weighted average incremental borrowing rate adjusted for collateralization (if the implicit rate is not determinable).  In general, the discount rates are based on either (i) information available at the lease commencement date or (ii) January 1, 2019 for leases existing at the adoption date for ASC 842.
