Co Promotion [Abstract] |
Avinza Co-Promotion | Avinza Co-Promotion In 2003, the Company and Organon Pharmaceuticals USA Inc. (Organon) entered into an agreement for the co-promotion of Avinza. Subsequently in 2006, the Company signed an agreement with Organon that terminated the Avinza co-promotion agreement between the two companies and returned Avinza co-promotion rights to the Company. In consideration of the early termination, the Company agreed to make quarterly royalty payments to Organon equal to 6.5% of Avinza net sales through December 31, 2013 and thereafter 6% through patent expiration, currently anticipated to be November 2017. In February 2007, Ligand and King Pharmaceuticals, Inc. ("King"), now a subsidiary of Pfizer, executed an agreement pursuant to which Pfizer acquired all of the Company’s rights in and to Avinza. Pfizer also assumed the Company’s co-promote termination obligation to make royalty payments to Organon based on net sales of Avinza. In connection with Pfizer's assumption of this obligation, Organon did not consent to the legal assignment of the co-promote termination obligation to Pfizer. Accordingly, Ligand remains liable to Organon in the event of Pfizer's default of the obligation. Therefore, Ligand recorded an asset as of February 26, 2007 to recognize Pfizer's assumption of the obligation, while continuing to carry the co-promote termination liability in the Company's consolidated financial statements to recognize Ligand’s legal obligation as primary obligor to Organon. This asset represents a non-interest bearing receivable for future payments to be made by Pfizer and is recorded at its fair value. The receivable and liability will remain equal and adjusted each quarter for changes in the fair value of the obligation including for any changes in the estimate of future net Avinza product sales. This receivable will be assessed on a quarterly basis for impairment (e.g. in the event Pfizer defaults on the assumed obligation to pay Organon). On a quarterly basis, management reviews the carrying value of the co-promote termination liability. In February 2014, Actavis launched a generic form of Avinza which resulted in a significant decrease in estimates of future net sales used to value the co-promote termination asset and liability. Due to assumptions and judgments inherent in determining the estimates of future net Avinza sales through November 2017, the actual amount of net Avinza sales used to determine the current fair value of the Company’s co-promote termination asset and liability may be materially different from current estimates. A summary of the co-promote termination liability as of December 31, 2014 and 2013 is as follows (in thousands):
Net present value of payments based on estimated future net Avinza product sales as of December 31, 2012 | $ | 12,534 |
Assumed payments made by Pfizer or assignee | (3,310 | )
Fair value adjustments due to passage of time | 2,522 |
Net present value of payments based on estimated future net Avinza product sales as of December 31, 2013 | 11,746 |
Assumed payments made by Pfizer or assignee | (1,243 | )
Fair value adjustments due to passage of time | (10,181 | )
Total co-promote termination liability as of December 31, 2014 | $ | 322 |
