Lease Guarantee

In connection with the spin-off by the Company of Facet Biotech Corporation (“Facet”) (the “Spin-Off”) 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 us for all matters related to the leases attributable to the period after the Spin-Off date. As of December 31, 2017, the total lease payments for the duration of the guarantee, which runs through December 2021, are approximately $45.1 million. 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.

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 Consolidated Balance Sheets as of December 31, 2017 and 2016, 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.

Irrevocable Letters of Credit

On June 30, 2016, the Company purchased a $75.0 million certificate of deposit, which is designated as cash collateral for the $75.0 million letter of credit issued on July 1, 2016 with respect to the first anniversary payment under the Noden Purchase Agreement. In addition, the Company provided an irrevocable and unconditional guarantee to Novartis, to pay up to $14.0 million of the remaining amount of the first anniversary payment not covered by the letter of credit. The Company concluded that both guarantees are contingent obligations and shall be accounted for in accordance with ASC 450, Contingencies. Further, it was concluded that both guarantees do not meet the conditions to be accrued at June 30, 2016 and December 31, 2016. On July 3, 2017, the first anniversary payment of $89.0 million was paid pursuant to the Noden Purchase Agreement and the $14.0 million guarantee expired. On July 31, 2017, the $75.0 million certificate of deposit matured, and on August 1, 2017, the letter of credit terminated.

Purchase Commitments

In connection with the Noden Transaction, Noden entered into an unconditional purchase obligation with Novartis to acquire all local finished goods inventory in certain countries upon transfer of the applicable marketing authorization rights in such country. The purchase is payable within 60 days after the transfer of the marketing authorization rights. The agreement does not specify minimum quantities but details pricing terms.

In addition, Noden and Novartis entered into a supply agreement pursuant to which Novartis will manufacture and supply to Noden a finished form of the Noden Products and bulk drug form of the Noden Products for specified periods of time prior to the transfer of manufacturing responsibilities for the Noden Products to another manufacturer. The supply agreement commits the Noden to a minimum purchase obligation of approximately $74.2 million and $105.8 million over the next twelve and thirty-six months, respectively. The Company expects Noden to meet this requirement

In June 2016, LENSAR and Coherent, Inc. entered into an Original Equipment Manufacturer agreement pursuant to which Coherent, Inc. will manufacture and supply to LENSAR Staccato Lasers by December 31, 2018. The supply agreement commits LENSAR to a minimum purchase obligation of approximately $1.3 million over the next three months. The Company expects LENSAR to meet this requirement.
