Commitments and Contingencies [Abstract] |
Commitments and Contingencies | Commitments and Contingencies Lease Commitments We lease facilities under various operating lease agreements in Basking Ridge, NJ, New York, NY, Irvine, CA, and Mountain View, CA, of which certain have escalation clauses and renewal options. We also lease equipment under certain noncancelable operating leases. Our leases expire from time to time through 2021. A summary of future minimum rental payments required under operating leases that have initial or remaining terms in excess of one year as of December 31, 2016 are as follows (in thousands):
Years ended |  | Operating Leases
2017 |  | 2,216.3 |
2018 |  | 1,723.5 |
2019 |  | 1,332.7 |
2020 |  | 792.1 |
2020 and thereafter |  | 168.1 |
Total minimum lease payments |  | $ | 6,232.7 |
Expense incurred under operating leases were approximately $2.1 million and $1.7 million for the years ended December 31, 2016 and 2015, respectively. Contingencies We have entered into a strategic collaboration with Sanford Research with the goal of developing a therapy for the treatment of T1D. The initial focus of the collaboration will be the execution of a prospective, randomized, placebo-controlled, double-blind clinical trial (The Sanford Project: T-Rex Study) to evaluate the safety and efficacy of the Company’s T regulatory cell product candidate, CLBS03, in adolescents with recent onset T1D. The Phase 2 study has an open and active IND in place and subject enrollment commenced in the first quarter of 2016. We were initially responsible for the supply of all study drug to the first 19 enrolled patients while Sanford assumed all patient and clinical site costs for subjects enrolled in their two centers as well as the expense associated with general clinical monitoring services. For the remaining 92 patients in the study, we will continue to be responsible for the supply of all study drug and the costs of study enrollment for sites outside of the Sanford centers. Under license agreements with third parties the Company is typically required to pay maintenance fees, make milestone payments and/or pay other fees and expenses and pay royalties upon commercialization of products. The Company also sponsors research at various academic institutions, which research agreements generally provide us with an option to license new technology discovered during the course of the sponsored research. Under the Hitachi Transaction, Hitachi may require the Company to purchase all of its ownership in PCT if a Change of Control has occurred (as defined in the Amended and Restated Operating Agreement of PCT), and if such Change of Control can reasonably be expected to have a material adverse effect on PCT’s ability to conduct its business in the ordinary course consistent with its past practice and its then current annual budget, at a price to be agreed upon by mutual agreement, provided, however, if mutual agreement is not obtained, the price will be determined by independent valuation firms. From time to time, the Company is subject to legal proceedings and claims, either asserted or unasserted, that arise in the ordinary course of business. While the outcome of pending claims cannot be predicted with certainty, the Company does not believe that the outcome of any pending claims will have a material adverse effect on the Company's financial condition or operating results.
