[1] The increase from December 31, 2023 reflects higher inventory levels for certain products mainly due to changes in net market demand, supply recovery and network strategy.

[2] Included in Other noncurrent assets. The decrease from December 31, 2023 is primarily driven by a reduction in acquired Seagen inventory, inclusive of the acquisition accounting fair value step up. See Note 2A. Based on our current estimates and assumptions, there are no recoverability issues for these amounts.
