Raw materials inventory included $0.8 million of pre-launch inventory as of December 31, 2023 and 2022, which consisted of FDKP received in November 2019.

The Company analyzed its inventory levels to identify inventory that may expire or has a cost basis in excess of its estimated realizable value. The Company also performed an assessment of projected sales and evaluated the lower of cost or net realizable value and the potential excess inventory on hand as of December 31, 2023 and 2022. Inventory that was forecasted to become obsolete due to expiration as well as inventory that does not meet acceptable standards is recorded in costs of goods sold in the consolidated statements of operations and a reserve for inventory in our consolidated balance sheets. As a result of this assessment there were inventory write-offs of $4.6 million and $2.2 million for the years ended December 31, 2023 and 2022, respectively.
