The Company is eligible to receive a mid-single digit percentage of all IXINITY quarterly net sales from January 1, 2023 until the first quarter of 2035, and will be entitled to milestone payments of up to $5.3 million.
At the inception of the Aptevo CPPA, the Company recorded $9.7 million as long-term royalty receivables in its consolidated balance sheet which included a $9.6 million upfront payment and a $50,000 one-time payment, which would be due if XOMA received more than $0.5 million in receipts for first quarter 2023 sales of IXINITY. At inception of the agreement, the Company concluded the one-time payment of $50,000 was probable and reasonably estimable. Therefore, the payment was recorded as a contingent liability under ASC 450 in the consolidated balance sheet at inception. The Company paid the one-time payment of $50,000 in June 2023 when related receipts exceeded $0.5 million.
During the year ended December 31, 2023, the Company received total commercial payments pursuant to the Aptevo CPPA of $1.7 million.
During the nine months ended September 30, 2024, the Company received commercial payments pursuant to the Aptevo CPPA of $0.8 million. In accordance with the cost recovery method, the cash received was recorded as a direct reduction of the long-term royalty and commercial payment receivables balance.
Though the Company is unable to reliably estimate its commercial payment stream from sales of future net sales and the commercial payments to be received under the agreement, it estimates the short-term portion of the receivables balance based on the past 12 months’ receipts. As such, as of September 30, 2024 and December 31, 2023, the Company recorded $2.2 million and $2.0 million, respectively, as short-term royalty and commercial payment receivables.
Under the cost recovery method, the Company does not expect to recognize any income related to milestones and commercial payments received until the purchase price has been fully collected. The Company performed its impairment assessment and no allowance for credit losses was recorded as of September 30, 2024 and December 31, 2023.

At the inception of the agreement, the Company recorded $10.0 million as long-term royalty receivables in its consolidated balance sheet.
As of September 30, 2024, no payments were probable to be received under the Palo RPA in the near term. Under the cost recovery method, the Company does not expect to recognize any income related to royalties received until the purchase price has been fully collected. The Company performed its impairment assessment and no allowance for credit losses was recorded as of September 30, 2024 and December 31, 2023.
