Commitments and Contingencies Disclosure [Abstract]

Operating Leases

The Company leases manufacturing, office and laboratory space in Rockville, Maryland under five leases that have terms that expire between 2018 and 2027 unless renewed. During the three months ended September 30, 2017, the Company entered into an agreement to sublease a portion of the space it leases. Under the terms of the sublease, the Company will receive a total of $2.4 million over the 30 month term.

The Rockville leases include a lease executed in July 2015 for space that the Company uses as its headquarters with office and laboratory space and manufacturing space currently under construction. Under the terms of the lease, which commenced on January 1, 2016, the Company received an assignment fee from the former tenant and a tenant improvement allowance from the landlord totaling $5.1 million. In July 2017, the Company executed a lease amendment for its headquarters building which extends the term of the lease to August 2027, restructures the rent due under the lease, and provides for an additional tenant improvement allowance from the landlord of $7.5 million, which was received during the third quarter. The assignment fee and tenant improvement allowances have been recorded as deferred rent and are being recognized over the new lease term.

The Company also leases office and laboratory space in South San Francisco under a lease that expires on February 28, 2018. During the year ended December 31, 2016, the Company entered into a sublease agreement for a portion of the South San Francisco space (see Note 4). As of September 30, 2017, future payments to be received by the Company under this sublease total approximately $0.3 million. In April 2017, the Company entered into a 72-month lease commencing in December 2017 for office and laboratory space which will replace our current South San Francisco location.

All of the leases contain rent escalation clauses and certain leases contain rent abatements. For financial reporting purposes, rent expense is charged to operations on a straight-line basis over the term of the lease.
