Work-in-process and finished goods as of September 30, 2017 and December 31, 2016 primarily include conversion costs because the materials used in its production were previously written off. During the three and nine months ended September 30, 2017, the Company recorded a write-down of inventory of approximately $0.3 million and $1.8 million, respectively, for inventory that was forecasted to become obsolete due to expiration which is recorded in costs of goods sold in the accompanying condensed consolidated statements of operations.
