Commitments and Contingencies	Note 9. Commitments and Contingencies Operating leases We leased various real properties under operating leases that generally require us to pay taxes, insurance, maintenance, and minimum lease payments. Some of our leases had options to renew. Operating Leases — California In December 2010, we entered into a commercial lease agreement with BMR-Gateway Boulevard LLC (“BMR”), as landlord, for office and research space at BMR’s Pacific Research Center in Newark, California. The initial term of the lease was approximately eleven and one-half years and included escalating rent payments which we recognized as lease operating expense on a straight-line basis. We were expected to pay approximately $17,869,000 in aggregate as rent over the term of the lease to BMR. In May 30, 2016, our Board of Directors approved a plan to wind down our current operations, having considered the decision to terminate the Pathway Study, our available strategic alternatives and our current cash position. On June 30, 2016, BMR filed a civil complaint for damages against us in Alameda County Superior Court. In its suit, BMR alleged that we had breached our lease agreement by winding down operations in our Newark facility. We disputed BMR’s allegations and opposed the litigation. However, on July 29, 2016, in order to avoid the costs and uncertainties inherent in any litigation, the parties to the BMR Suit agreed to settle the case. As part of the settlement agreement with BMR, in August 2016, we made a one-time settlement payment of $800,000 to BMR and forfeited our security deposit of $333,000 with BMR. The suit was dismissed and we exited the Newark facility as of August 1, 2016. In March 2013, we entered into a commercial lease agreement with Prologis, L.P. (“Prologis”), as landlord, for office and research space in Sunnyvale, California. The facility was for operations that supported our clinical development activities. The initial term of the lease was ten years and included escalating rent payments which we recognized as lease operating expense on a straight-line basis. We were expected to pay approximately $3,497,000 in aggregate rent over the term of the lease. As part of the lease, Prologis had agreed to provide us financial allowances to build initial tenant improvements, subject to customary terms and conditions relating to landlord-funded tenant improvements. The tenant improvements were recorded as leasehold improvement assets and amortized over the term of the lease. In May 30, 2016, our Board of Directors approved a plan to wind down our current operations, having considered the decision to terminate the Pathway Study, our available strategic alternatives and our current cash position. As part of the wind down of our operations, we terminated our lease agreement by entering into a series of agreements with both Miltenyi Biotec, Inc., a California subsidiary of a German research tools company (“Miltenyi”), and the company’s landlord that provided for an early exit from the Sunnyvale facility. As part of these transactions, we assigned our existing real property lease to the Sunnyvale facility to Miltenyi, sold certain equipment in this facility to Miltenyi for $650,000, and received $40,000 as refund of our security deposit from Prologis. No lease termination fee was paid to exit this facility. As of August 1, 2016, the Company has exited its previously leased facilities in both Newark and Sunnyvale, California. No further lease payments are owed for either facility. With the exception of the operating leases discussed above, we have not entered into any significant off balance sheet financial arrangements and have not established any special purpose entities. We have not guaranteed any debts or commitments of other entities or entered into any options on non-financial assets.
