As of June 30, 2022 and December 31, 2021, included in finished goods inventory was $11.4 million and $18.6 million of HEPLISAV-B inventory, respectively. The remaining balance in finished goods inventory was CpG 1018 adjuvant for our collaboration partners.

 

We recorded prepaid manufacturing costs related to prepayments made to third-party manufacturers of CpG 1018 adjuvant, of $54.5 million and $159.7 million as of June 30, 2022 and December 31, 2021, respectively. We expect these costs to be converted into inventory within the next twelve months.
