Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On May 4, 2020, we entered into a lease agreement, or Lease Agreement, with Wateridge Property Owner, LP, with respect to facilities in the building at 10770 Wateridge Circle, San Diego, California 92121. Under the Lease Agreement, we agreed to lease approximately 45,000 square feet of space in the 10770 Wateridge Circle Building for a term of 124 months, beginning on March 1, 2021 (or on such later date as described in the Lease Agreement). The terms of the Lease Agreement provide us with an option to extend the term of the lease for an additional five years, as well as a one-time option we have to terminate the lease after seven years with the payment of a termination fee. The monthly base rent will be $4.20 per rentable square foot, and will be increased by 3% annually.
