[1] | Deferred payments represent the acquisition date fair value of the $5,000 in deferred consideration to be paid to Ipsen. The Company will make payments of $2,500 on each of the first and second anniversaries of closing, which the closing date of the acquisition was December 19, 2024. The Company will accrete the $724, which represents the difference between the total deferred payments amount due of $5,000 and the acquisition date fair value of $4,276, to interest expense in its Statements of Operations over the course of the two-year period using the effective interest rate methodology.
[2] | Inventory consists of raw materials, semi-finished goods and finished goods. Finished goods, semi-finished goods and raw materials inventory were valued on the acquisition date at fair value and resulted in a $5,510 step-up in inventory value compared to a $7,500 carrying value. Determining the fair value of inventory included making estimates of costs to complete and to sell semi-finished and finished goods inventory.
