Gross-to-Net Sales Adjustments

To date our only source of product revenue has been from the U.S. sales of UKONIQ, which we began shipping to our customers in February 2021. We record our best estimate for sales discounts and allowances to which customers are likely to be entitled. The reconciliation of gross product sales to net product sales by each significant category of gross-to-net adjustments was as follows for the year ended December 31, 2021:

	Year ended

Gross-to-net adjustments:
Chargebacks and administrative fees		(840)
