Revenue from product sales is related to sales of our commercial products to our customers. For detailed discussions of our revenues from collaboration and government contracts, see “Note 4 – Sponsored Research and License Agreements and Government Contracts.”
Our product sales revenue is net of chargebacks, discounts and fees, government and other rebates and returns. Of the total discounts and allowances from gross product sales for the years ended December 31, 2024, 2023 and 2022, $64.0 million, $41.5 million and $30.9 million, respectively, was accounted for as additions to revenue reserves and refund liability, and $1.0 million, $1.3 million and $0.9 million, respectively, as reductions in accounts receivable (as it relates to allowance for prompt pay discount) and prepaid and other current assets (as it relates to certain chargebacks and other fees that were prepaid) in the balance sheet. The following tables summarize the activities in chargebacks, discounts and fees, government and other rebates and returns that were accounted for revenue reserves and refund liability, for each of the periods presented (in thousands):
