Operating leases

The Company is obligated under certain non-cancellable operating leases for its facilities, which expire on various dates through 2027. Certain facility leases contain predetermined fixed escalation of minimum rents.

The deferred rent liability was $0.4 million as of December 31, 2020 and 2019. Total rental expense amounted to $0.7 million, $0.5 million, and $0.4 million for the years ended December 31, 2020, 2019, and 2018, respectively, and is recorded in operating expenses in the consolidated statements of operations.

Litigation

The Company is subject to certain legal proceedings and claims that arise in the normal course of business. In the opinion of management, the Company does not believe that the amount of liability, if any, as a result of these proceedings and claims will have a materially adverse effect on the Company’s consolidated financial position, results of operations, and cash flows. As of December 31, 2020, and 2019, the Company does not have any contingency reserves established for any litigation liabilities.
