Leases

3 Months Ended

Mar. 31, 2020

We have operating leases consisting of office space for our Emeryville, California headquarters and for our various subsidiaries. In March 2020, our operating lease for our former headquarters in San Diego, California and the co-terminus sublease arrangement with our sublessee expired in accordance with the terms of the leases. In February 2020, we entered into a lease for office space in Maidenhead, United Kingdom, for a five-year term with aggregate lease payments of approximately $1.5 million. Operating lease assets represent our right to use an underlying asset for the lease term. Operating lease liabilities represent the present value of lease payments over the lease term, discounted using an estimate of our secured incremental borrowing rate.
