The Company is required to perform stability testing on select lots of EXPAREL. In October 2019, a single validation lot of EXPAREL manufactured at the Company’s contract manufacturing site located in the United Kingdom did not meet its required stability specification. The Company has temporarily halted production on the line while it investigates the root cause of the failure. Inventory from this line totals approximately $10.5 million. Depending on the outcome of the investigation and discussions with the FDA, it may be determined that some or all of this inventory may be unsellable. At this stage, no determination of an amount is possible.
