Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	13. Commitments and Contingencies Lease Guarantee In connection with the spin-off by the Company of Facet Biotech Corporation (“Facet”), the Company entered into amendments to the leases for the Company’s former facilities in Redwood City, California, under which Facet was added as a co-tenant, and a Co-Tenancy Agreement, under which Facet agreed to indemnify the Company for all matters related to the leases attributable to the period after the spin-off date. In April 2010, Abbott Laboratories acquired Facet and later renamed the entity AbbVie Biotherapeutics, Inc. (“AbbVie”). If AbbVie were to default under its lease obligations, the Company could be held liable by the landlord as a co-tenant and, thus, the Company has in substance guaranteed the payments under the lease agreements for the Redwood City facilities. As of March 31, 2020, the total lease payments for the duration of the guarantee, which runs through December 2021, are approximately $19.7 million. The Company prepared a discounted, probability weighted cash flow analysis to calculate the estimated fair value of the lease guarantee as of the spin-off. The Company was required to make assumptions regarding the probability of Facet’s default on the lease payment, the likelihood of a sublease being executed and the times at which these events could occur. These assumptions are based on information that the Company received from real estate brokers and the then-current economic conditions, as well as expectations of future economic conditions. The fair value of this lease guarantee was charged to Additional paid-in capital upon the spin-off and any future adjustments to the carrying value of the obligation will also be recorded in Additional paid-in capital. The Company has recorded a liability of $10.7 million on its Condensed Consolidated Balance Sheets as of March 31, 2020 and December 31, 2019, related to this guarantee. In future periods, the Company may adjust this liability for any changes in the ultimate outcome of this matter that are both probable and estimable.

In May 2019, Noden DAC and Novartis entered into an amended supply agreement pursuant to which Novartis will supply to Noden DAC a bulk tableted form of the Noden Products through 2020 and API through June 2021. The supply agreement may be terminated by either party for material breach that remains uncured for a specified time period. Under the terms of the amended supply agreement, Noden DAC is committed to purchase certain quantities of bulk product and API that would amount to approximately $55.7 million through June 2021, of which $43.1 million is committed over the next twelve months, which are guaranteed by the Company. While the supply agreement provides that the parties will agree to reasonable accommodations with respect to changes in firm orders, the Company expects that Noden DAC will meet the requirements of the supply agreement, unless otherwise negotiated. LENSAR entered into various supply agreements for the manufacture and supply of certain components. The supply agreements commit LENSAR to a minimum purchase obligation of approximately $8.0 million over the next twelve months, a portion of which is guaranteed by the Company.
