Operating Leases

On February 9, 2016, the Company entered into a non-cancelable facilities operating sublease (the “2016 Sublease”). On March 15, 2019, the Company amended and restated the 2016 Sublease (as amended, the “Amended 2016 Sublease”) to include additional square footage to be used for office space, which the Company took possession of upon entering into the Amended 2016 Sublease. The Amended 2016 Sublease expires in August 2025. The base rent under the Amended 2016 Sublease is currently $32,254 per month plus the Company’s prorated share of the sublandlord’s operating expense and is subject to annual rent increases of 3%.

On January 30, 2019, the Company entered into a new lease to be used for office and laboratory space (the “New Premises”), which the Company took possession of on June 1, 2019 (the “2019 Lease”). On August 2, 2019, the Company amended the 2019 Lease (as, the “Amended 2019 Lease”) to include additional space to be used for office and laboratory space (the “Expansion Premises”), which the Company expects to take possession of on April 1, 2020. The Amended 2019 Lease expires in March 2030. Upon expiration of the Amended 2016 Sublease, the Amended 2019 Lease will also cover the space the Company is currently subleasing under the Amended 2016 Sublease. Base rent is abated until April 1, 2020 for the New Premises and until seven months after delivery of the Expansion Premises for the Expansion Premises, after which the base rent will be $19,646 per month for the New Premises and $18,178 per month for the Expansion Premises, each subject to annual rent increases of 3%. In connection with this lease, the Company executed a $39,000 letter of credit, which has not been drawn down on. Additionally, there is a base rate adjustment of 8.5% per annum multiplied by the outstanding balance of amounts paid for tenant improvements. The budgeted amounts of tenant improvements are approximately $1,477,000 for the New Premises and $1,517,000 for the Expansion Premises, which are to be fully reimbursed by the landlord.

The future minimum payments for the operating leases are as follows (in thousands):

Legal Proceedings

The Company, from time to time, may be party to litigation arising in the ordinary course of business. The Company is not a party to any litigation or legal proceedings, nor is management aware of any pending or threatened litigation that, in the opinion of the Company’s management, are likely to have a material adverse effect on the Company’s business. At each reporting date, the Company evaluates whether a potential loss amount or a potential range of loss is probable and reasonably estimable under the provisions of the authoritative guidance that addresses accounting for contingencies. The Company expenses the costs related to its legal proceedings as incurred.
