We recorded approximately $1.3 billion of acquired inventory, which includes measurement period adjustments, related to SKYCLARYS as a result of our acquisition of Reata in September 2023. The fair value was determined based on the estimated selling price of the inventory, less the remaining manufacturing and selling costs and a normal profit margin on those manufacturing and selling efforts. This fair value step-up adjustment is being amortized to cost of sales within our condensed consolidated statements of income when the inventory is sold, which is expected to be within approximately 3 years from the acquisition date. For the three months ended March 31, 2024, amortization from the fair value step-up adjustment as a result of inventory sold was approximately $44.1 million. For additional information on our acquisition of Reata, please read Note 2, Acquisitions, to these condensed consolidated financial statements.
