Finished goods manufactured by the Company have a shelf life of approximately 24 months from the date of manufacture.

The Company reduces its inventory to net realizable value for potentially excess, dated or obsolete inventory based on an analysis of forecasted demand compared to quantities on hand and any firm purchase orders, as well as product shelf life. During the three and nine months ended September 30, 2019, the Company expensed $0.9 million to cost of sales for unabsorbed manufacturing overhead costs related to the operations of the United Kingdom facility at Patheon U.K. Limited, compared to $1.4 million and $5.0 million in the comparable periods in the prior year. The Company determined that no write-downs to finished goods inventory for potentially excess, dated or obsolete inventory were required.
